• how to stop deferred emails

  - by Will K

  I have a postfix mail gateway. At the same time, every other host is set to use this gateway as the relay. We have some automated outgoing emails sent from some hosts. I believe the gateway trys to send a deferred status back to the system started this. But that system is a null client, which sends but not receive any email Is there anyway to stop sending the deferred status? e.g. postfix/smtp[35725]: 2F6A155C256: to=, relay=none, delay=260862, delays=260862/0.01/0/0, dsn=4.4.1, status=deferred (connect to orange.mydom.com[192.168.1.5]:25: Connection refused) Thanks

• WPF - Overlapping Custom Tabs in a TabControl and ZIndex

  - by Rachel

  Problem I have a custom tab control using Chrome-shaped tabs that binds to a ViewModel. Because of the shape, the edges overlap a bit. I have a function that sets the tabItem's ZIndex on TabControl_SelectionChanged which works fine for selecting tabs, and dragging/dropping tabs, however when I Add or Close a tab via a Relay Command I am getting unusual results. Does anyone have any ideas? Default View http://i193.photobucket.com/albums/z197/Lady53461/tabs_default.jpg Removing Tabs http:/i193.photobucket.com/albums/z197/Lady53461/tabs_removing.jpg Adding 2 or more Tabs in a row http:/i193.photobucket.com/albums/z197/Lady53461/tabs_adding.jpg Code to set ZIndex private void PrimaryTabControl_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (e.Source is TabControl) { TabControl tabControl = sender as TabControl; ItemContainerGenerator icg = tabControl.ItemContainerGenerator; if (icg.Status == System.Windows.Controls.Primitives.GeneratorStatus.ContainersGenerated) { foreach (object o in tabControl.Items) { UIElement tabItem = icg.ContainerFromItem(o) as UIElement; Panel.SetZIndex(tabItem, (o == tabControl.SelectedItem ? 100 : 90 - tabControl.Items.IndexOf(o))); } } } } By using breakpoints I can see that it is correctly setting the ZIndex to what I want it to, however the layout is not displaying the changes. I know some of the changes are in effect because if none of them were working then the tab edges would be reversed (the right tabs would be drawn on top of the left ones). Clicking a tab will correctly set the zindex of all tabs (including the one that should be drawn on top) and dragging/dropping them to rearrange them also renders correctly (which removes and reinserts the tab item). The only difference I can think of is I am using the MVVM design pattern and the buttons that Add/Close tabs are relay commands. Does anyone have any idea why this is happening and how I can fix it?? p.s. I did try setting a ZIndex in my ViewModel and binding to it, however the same thing happens when adding/removing tabs via the relay command. EDIT: Being a new user I couldn't post images and could only post 1 link. Images just show a picture of what the tags render as after each scenario. Adding more then 1 at a time will not reset the zindex of other recently-added tabs so they go behind the tab on the Right, and closing tabs does not correctly render the ZIndex of the SelectedTab that replaces it and it shows up behind the tab on its right.

• Setting up Elgg SMTP

  - by dde

  I am new to Elgg. I installed v1.7/ Right now, our newly registered users are not receiving activation email. I need to change SMTP settings and have Elgg use a relay server and not our company email server. The hosting company authorized me to use such relay. Now, I guess I have to edit some php file, somewhere, and type email server address. Can someone tell me how to change SMTP settings (and, perhaps those other settings you find in the initial setup page) ?

• CodeIgniter - Disallowed Key Characters via $_GET

  - by rkj

  I am getting echoed "Disallowed Key Characters." in my CodeIgniter when I have a http_cookie sent via GET from a SSL relay site (a payment gateway) to my application. My question is if there's any way that I can get this http_cookie through this "_clean_input_keys" method that cause this Disallowed-message and exits? The parameter contains a getenv("HTTP_COOKIE") set into a hidden input and needs to be used to keep the session alive even though it will be sent to the relay site and back again. The HTTP_COOKIE string looks like: &HTTP_COOKIE=PHPSESSID=775572c8c3b161bc957281aa901eb09c;%20ci_session=a%3A4%3A{s%3A10%3A%22session_id%22%3Bs%3A32%3A%229666689e0c8e4f26fb38889351765304%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A14%3A%2127.0.0.1%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A50%3A%22Mozilla%2F5.0+%28Macintosh%3B+U%3B+Intel+Mac+OS+X+10.6%3B+da%22%3Bs%3A13%3A%22last_activity%22%3Bs%3A10%3A%221271145332%22%3B}d9b9df5d8a0b51f303cbe6bb4bbe497e

• Access is denied trying to access a sMetabasePath on a SMTP Server from a different Web Server

  - by RJ

  I have written a C# dot net application that updates the SMTP relay restriction list in IIS 6. Running the application locally works great and I can add/remove IPs/DNS from the relay restriction list without any problem. Now I need to do the same for a SMTP server that is not running on the same webserver that I have the application running. So I have the web application on webserver A and the SMTP server on webserver/smtp server B. My app pool is running under a domain user and I have given the same user rights to the SMTP server under the security tab in the SMTP Virtual Server property window. I thought I could simply change the sMetabasePath from "IIS://localhost/smtpsvc/1" to "IIS://10.171.243.134/smtpsvc/1" and everything would just work but I get an "Access is denied" error. So I must have to do something else to get this to work. I even gave the domain user full admin rights on the SMTP server to no avail. Any ideas

• Postfix - am I sending spam?

  - by olrehm

  today I received like 30 messages within 5 minutes telling me that some mail I send could not be delivered, mostly to *.ru email addresses which I did not send any mail to. I have my own webserver (postfix/dovecot) set up using this guide (http://workaround.org/ispmail/lenny) but adjusted a little bit for Ubuntu. I tested whether I am an Open Relay which I am apparently not. Now there are two possible reasons for the above mentioned emails: Either I am sending out spam, or somebody wants me to think that, correct? How can I check this? I selected one particular address that I supposedly send spam to. Then I searched my mail.log for this entry. I found two blocks that record that somebody from the server connected to my server and delivered some message to two different users. I cannot find an entry reporting that anyone from my server send an email to that server. Does this mean its just some mail to scare me or could it still have been send by me in the first place? Here is one such block from the log (I replaced some confidential stuff): Jun 26 23:23:28 mycustomernumber postfix/smtpd[29970]: connect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: 044991528995: client=mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/cleanup[29974]: 044991528995: message-id=<[email protected]> Jun 26 23:23:29 mycustomernumber postfix/qmgr[3369]: 044991528995: from=<>, size=2198, nrcpt=1 (queue active) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) ESMTP::10024 /var/lib/amavis/tmp/amavis-20110626T223137-28598: <> -> <[email protected]> SIZE=2198 Received: from mycustomernumber.stratoserver.net ([127.0.0.1]) by localhost (rehmsen.de [127.0.0.1]) (amavisd-new, port 10024) with ESMTP for <[email protected]>; Sun, 26 Jun 2011 23:23:29 +0200 (CEST) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) Checking: YakjkrdFq6A8 [195.144.251.97] <> -> <[email protected]> Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: disconnect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) lookup_sql_field(id) (WARN: no such field in the SQL table), "[email protected]" result=undef Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: connect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: 0A1FA1528A21: client=localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/cleanup[29974]: 0A1FA1528A21: message-id=<[email protected]> Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: from=<>, size=2841, nrcpt=1 (queue active) Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: disconnect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) FWD via SMTP: <> -> <[email protected]>,BODY=7BIT 250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21 Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) Passed CLEAN, [195.144.251.97] [195.144.251.97] <> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: YakjkrdFq6A8, Hits: 2.249, size: 2197, queued_as: 0A1FA1528A21, 2882 ms Jun 26 23:23:32 mycustomernumber postfix/smtp[29975]: 044991528995: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=3.3, delays=0.39/0.01/0.01/2.9, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21) Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 044991528995: removed Jun 26 23:23:33 mycustomernumber postfix/smtp[29980]: 0A1FA1528A21: to=<[email protected]>, orig_to=<[email protected]>, relay=mx3.hotmail.com[65.54.188.110]:25, delay=1.2, delays=0.15/0.02/0.51/0.55, dsn=2.0.0, status=sent (250 <[email protected]> Queued mail for delivery) Jun 26 23:23:33 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: removed Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection rate 1/60s for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection count 1 for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max cache size 1 at Jun 26 23:23:28 I can provide more info if you tell me what you need to know.

• Securing smtp with login

  - by Paul Peelen

  I have a ispconfig server, and it seems that someone is using it to send spam. I got about 130 "Mail Delivery System" email about declined send email. This spammer uses my email address as sent from adress, so I get all these email adresses to my mail. I am using Postfix and Courier. I installed my server according to this guide: http://www.howtoforge.com/perfect-server-debian-lenny-ispconfig3-p3 I did this a few months ago. My question: Can I secure my server to require login to be able to send email, and if so... how? Thanks!

  Hello I have a problem with maildrop. I have read dozens of webs/howto/emails but couldnt solve it. My objective is moving automatically spam messages to a spam folder. My email server is working perfectly. It marks spam in subject and headers using spamassasin. My box has: Ubuntu 9.04 Web: Apache2 + Php5 + MySQL MTA: Postfix 2.5.5 + SpamAssasin + virtual users using mysql IMAP: Courier 0.61.2 + Courier AuthLib WebMail: SquirrelMail I have read that I could use Squirrelmail directly (not a good idea), procmail or maildrop.

• Send email from postfix server to outside email client

• authorize.net SIM PCI compliance

  - by David

  Does anyone know if authorize.net's SIM rids you of having to be PCI compliant? The payment form is hosted on authorize.net's site and they're processing the payment. I know you can do a relay response which basically puts some of the transaction details in a url that goes back to your website(to display a receipt). I'm not sure what all information gets put into the url though. I'm wondering if that makes you have to become PCI compliant?

• Benchmarking MySQL Replication with Multi-Threaded Slaves

  - by Mat Keep

  0 0 1 1145 6530 Homework 54 15 7660 14.0 Normal 0 false false false EN-US JA X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:Cambria; mso-ascii-font-family:Cambria; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Cambria; mso-hansi-theme-font:minor-latin; mso-ansi-language:EN-US;} The objective of this benchmark is to measure the performance improvement achieved when enabling the Multi-Threaded Slave enhancement delivered as a part MySQL 5.6. As the results demonstrate, Multi-Threaded Slaves delivers 5x higher replication performance based on a configuration with 10 databases/schemas. For real-world deployments, higher replication performance directly translates to: · Improved consistency of reads from slaves (i.e. reduced risk of reading "stale" data) · Reduced risk of data loss should the master fail before replicating all events in its binary log (binlog) The multi-threaded slave splits processing between worker threads based on schema, allowing updates to be applied in parallel, rather than sequentially. This delivers benefits to those workloads that isolate application data using databases - e.g. multi-tenant systems deployed in cloud environments. Multi-Threaded Slaves are just one of many enhancements to replication previewed as part of the MySQL 5.6 Development Release, which include: · Global Transaction Identifiers coupled with MySQL utilities for automatic failover / switchover and slave promotion · Crash Safe Slaves and Binlog · Optimized Row Based Replication · Replication Event Checksums · Time Delayed Replication These and many more are discussed in the “MySQL 5.6 Replication: Enabling the Next Generation of Web & Cloud Services” Developer Zone article  Back to the benchmark - details are as follows. Environment The test environment consisted of two Linux servers: · one running the replication master · one running the replication slave. Only the slave was involved in the actual measurements, and was based on the following configuration: - Hardware: Oracle Sun Fire X4170 M2 Server - CPU: 2 sockets, 6 cores with hyper-threading, 2930 MHz. - OS: 64-bit Oracle Enterprise Linux 6.1 - Memory: 48 GB Test Procedure Initial Setup: Two MySQL servers were started on two different hosts, configured as replication master and slave. 10 sysbench schemas were created, each with a single table: CREATE TABLE `sbtest` (    `id` int(10) unsigned NOT NULL AUTO_INCREMENT,    `k` int(10) unsigned NOT NULL DEFAULT '0',    `c` char(120) NOT NULL DEFAULT '',    `pad` char(60) NOT NULL DEFAULT '',    PRIMARY KEY (`id`),    KEY `k` (`k`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 10,000 rows were inserted in each of the 10 tables, for a total of 100,000 rows. When the inserts had replicated to the slave, the slave threads were stopped. The slave data directory was copied to a backup location and the slave threads position in the master binlog noted. 10 sysbench clients, each configured with 10 threads, were spawned at the same time to generate a random schema load against each of the 10 schemas on the master. Each sysbench client executed 10,000 "update key" statements: UPDATE sbtest set k=k+1 WHERE id = <random row> In total, this generated 100,000 update statements to later replicate during the test itself. Test Methodology: The number of slave workers to test with was configured using: SET GLOBAL slave_parallel_workers=<workers> Then the slave IO thread was started and the test waited for all the update queries to be copied over to the relay log on the slave. The benchmark clock was started and then the slave SQL thread was started. The test waited for the slave SQL thread to finish executing the 100k update queries, doing "select master_pos_wait()". When master_pos_wait() returned, the benchmark clock was stopped and the duration calculated. The calculated duration from the benchmark clock should be close to the time it took for the SQL thread to execute the 100,000 update queries. The 100k queries divided by this duration gave the benchmark metric, reported as Queries Per Second (QPS). Test Reset: The test-reset cycle was implemented as follows: · the slave was stopped · the slave data directory replaced with the previous backup · the slave restarted with the slave threads replication pointer repositioned to the point before the update queries in the binlog. The test could then be repeated with identical set of queries but a different number of slave worker threads, enabling a fair comparison. The Test-Reset cycle was repeated 3 times for 0-24 number of workers and the QPS metric calculated and averaged for each worker count. MySQL Configuration The relevant configuration settings used for MySQL are as follows: binlog-format=STATEMENT relay-log-info-repository=TABLE master-info-repository=TABLE As described in the test procedure, the slave_parallel_workers setting was modified as part of the test logic. The consequence of changing this setting is: 0 worker threads:    - current (i.e. single threaded) sequential mode    - 1 x IO thread and 1 x SQL thread    - SQL thread both reads and executes the events 1 worker thread:    - sequential mode    - 1 x IO thread, 1 x Coordinator SQL thread and 1 x Worker thread    - coordinator reads the event and hands it to the worker who executes 2+ worker threads:    - parallel execution    - 1 x IO thread, 1 x Coordinator SQL thread and 2+ Worker threads    - coordinator reads events and hands them to the workers who execute them Results Figure 1 below shows that Multi-Threaded Slaves deliver ~5x higher replication performance when configured with 10 worker threads, with the load evenly distributed across our 10 x schemas. This result is compared to the current replication implementation which is based on a single SQL thread only (i.e. zero worker threads). Figure 1: 5x Higher Performance with Multi-Threaded Slaves The following figure shows more detailed results, with QPS sampled and reported as the worker threads are incremented. The raw numbers behind this graph are reported in the Appendix section of this post. Figure 2: Detailed Results As the results above show, the configuration does not scale noticably from 5 to 9 worker threads. When configured with 10 worker threads however, scalability increases significantly. The conclusion therefore is that it is desirable to configure the same number of worker threads as schemas. Other conclusions from the results: · Running with 1 worker compared to zero workers just introduces overhead without the benefit of parallel execution. · As expected, having more workers than schemas adds no visible benefit. Aside from what is shown in the results above, testing also demonstrated that the following settings had a very positive effect on slave performance: relay-log-info-repository=TABLE master-info-repository=TABLE For 5+ workers, it was up to 2.3 times as fast to run with TABLE compared to FILE. Conclusion As the results demonstrate, Multi-Threaded Slaves deliver significant performance increases to MySQL replication when handling multiple schemas. This, and the other replication enhancements introduced in MySQL 5.6 are fully available for you to download and evaluate now from the MySQL Developer site (select Development Release tab). You can learn more about MySQL 5.6 from the documentation  Please don’t hesitate to comment on this or other replication blogs with feedback and questions. Appendix – Detailed Results

• email dropbox between two mutually untrusted sites

  - by user52874

  I've an interesting problem that I thought was straightforward, but turns out I think I'm whistling down the wrong path. It has to do with (shudder) email. I thought I was done with needing to know about email guts ten years ago; I was wrong. Anyway. Simply put, I need to figure out how to relay outgoing email that is not targetted in our domain from our domain into a 'dropbox' in a DMZ, and the Other Guys can retrieve that email from their side of the DMZ and distribute it accordingly, even out to the public internet if need be. There will be no [un-established] traffic coming back to Our side from anywhere; any attempts to do so are dropped with malicious prejudice. Our side is postfix running on scilinux6.1. The DMZ boxes are redhat5.4. The Other Guys are M$ Exchange. The firewalls are set up such that data can go from Our Side downsec to the DMZ, but not upsec from the DMZ into Our Side. Same for the Other Guys. My first thinking was simply to set up postfix on a box in the DMZ and tell them to set up fetchmail or whatever the M$ equivalent is, but then I started remembering that postfix wants to actively relay email onwards, rather than hold it and wait for someone to 'reach in' and retrieve it. I'm not sure I've explained this well, but hopefully it's clear enough that someone can point me in the right direction. I seem to remember having done this before, but it was a looong time ago. thanks!

• Openfire on EC2 with Jingle

  - by Bjorn Roche

  I would like to run Openfire (or another XMPP server) on EC2. At the moment this is just for testing, so easy setup and configuration are important, as is low cost. At some point, however, if things go well, it will be important to scale this. Ideally, it would be nice to not have to switch software when the scaling happens, but if a switch needs to happen later it certainly can. My requirements are: basic XMPP services, including muc and pubsub. Logins controlled from an external API. Preferably, when a user attempts to connect, the XMPP server checks with the api to see if their username and password are correct, but I can also have the API keep the XMPP server up to date on new users, deleted users, pasword changes and so on. I see Openfire has a "user service" API. Not ideal, but it looks workable. Jingle, including relay and STUN. It's not at all clear to me if the Jingle Nodes plugin takes care of this. I'm a bit confused about what's required to set this up, and I'd rather know in advance than be confused along the way :). eg It seems like STUN servers require more than one IP address. Can Openfire do all this for me, including stun and media relay on a single machine? Is this hard to configure on EC2 with Openfire? What are the basic steps? Would this be easier with something else like, say Tigase? What about database? Should I use amazon's database service, or run a db on the same machine? Would the server be compatible with a service like http://www.siteuptime.com/ Thanks!
