  • postfix smtp relay script

    - by Peter Sander
    I have a Postfix server and using it with Outlook (POP/SMTP). I have different sender addresses for an account. Now I want to configure a relay for a specific sender address. For example I have postfix for my main domain domain1.com. Now I have a sender address that is domain2.com. For that sender address I want that postfix to relay mail to a second SMTP server. I think that should be possible without problems. But the problem is that I have to create a SSH tunnel to the second server to connect to the SMTP server. But I cant use a persistent SSH connection so I want to know if it is possible that postfix executes some script before relaying the mail to the second SMTP server. I already found some information for executing a script when incomming emails but I only want to establish the SSH tunnel before postfix relays the mail to the second SMTP server.

  • Tomcat 6 HTTPS connector: keep alive timeout not being respected

    - by sehugg
    I'm using Tomcat 6.0.24 on Ubuntu (JDK 1.6) with an app that does Comet-style requests on an HTTPS connector (directly against Tomcat, not using APR). I'd like to set the keep-alive to 5 minutes so I don't have to refresh my long-polling connections. Here is my config: <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="1000" keepAliveTimeout="330000" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" /> Unfortunately it seems that the server closes the connection after 65 seconds. The pcap from a sample session goes something like this: T=0 Client sends SYN to server, handshake etc. T=65 Server sends FIN to client T=307 Client sends FIN to server (I'm guessing the 5 minute timeout on the client is due to the HTTP lib not detecting the socket close on the server end, but in any case -- the server shouldn't be closing the connection that early) (edit: this works as expected when using the standard HTTP connector)

  • DKIM for email through Google Apps domain with external outbound relay

    - by David Gardiner
    I'd like to enable the new Domain Keys DKIM email authentication feature for a domain hosted in Google Apps. Some of my users use an external SMTP gateway (such that when they send email, it doesn't go through smtp.gmail.com). I have an SPF record configured for the domain, and this allows the external SMTP gateways as valid SMTP hosts. (I realise SPF is different to DKIM) Will enabling DKIM adversely affect the external gateway email? eg. Are the externally sent emails at risk of being marked as spam because they would not have the DKIM signature, or will DKIM only positively benefit emails sent through Google's SMTP server?

  • SMTP mailbox unavailable - intermittent and self-inflicted

    - by user134451
    I have an app that runs daily, sending confirmation emails to dozens of customers. Emails are sent using SMTP with authentication. The app also has some error handling, and occasionally anonymous SMTP is used to notify the webmaster that an e-mail issue has been encountered (a malformed email address, usually). Whenever these warning notifications are sent, the customer notifications that follow throw an error: "Mailbox unavailable. The server response was: 5.7.1 Unable to relay". The customer notification emails are sent, but my app drops into the exception handler. And all subsequent customer notification emails have this problem. Everything is fine next time the programs run, until a webmaster warning email is sent. Anyone have an ideas what would cause this? My first thought was that the client didn't like being switched back and forth between anonymous to authenticated modes. I created a separate client for each mode, but that didn't help.

  • Could Python's logging SMTP Handler be freezing my thread for 2 minutes?

    - by Oddthinking
    A rather confusing sequence of events happened, according to my log-file, and I am about to put a lot of the blame on the Python logger, which is a bold claim. I thought I should get some second opinions about whether what I am saying could be true. I am trying to explain why there is are several large gaps in my log file (around two minutes at a time) during stressful periods for my application when it is missing deadlines. I am using Python's logging module on a remote server, and have set-up, with a configuration file, for all logs of severity of ERROR or higher to be emailed to me. Typically, only one error will be sent at a time, but during periods of sustained problems, I might get a dozen in a minute - annoying, but nothing that should stress SMTP. I believe that, after a short spurt of such messages, the Python logging system (or perhaps the SMTP system it is sitting on) is encountering errors or congestion. The call to Python's log is then BLOCKING for two minutes, causing my thread to miss its deadlines. (I was smart enough to move the logging until after the critical path of the application - so I don't care if logging takes me a few seconds, but two minutes is far too long.) This seems like a rather awkward architecture (for both a logging system that can freeze up, and for an SMTP system (Ubuntu, sendmail) that cannot handle dozens of emails in a minute**), so this surprises me, but it exactly fits the symptoms. Has anyone had any experience with this? Can anyone describe how to stop it from blocking? ** EDIT: I actually counted. A little under 4000 short emails in two hours. So far more than I suggested, sorry. But enough to over-fill a Sendmail's buffers?

  • Postfix connects to wrong relay?

    - by Eric
    I am trying to set up postfix on my ubuntu server in order to send emails via my isp's smtp server. I seem to have missed something because the mail.log tells me: Jan 19 11:23:11 mediaserver postfix/smtp[5722]: CD73EA05B7: to=<[email protected]>, relay=new.mailia.net[85.183.240.20]:25, delay=6.2, delays=5.7/0.02/0.5/0, dsn=4.7.0, status=deferred (SASL authentication failed; server new.mailia.net[85.183.240.20] said: 535 5.7.0 Error: authentication failed: ) The relay "new.mailia.net[85.183.240.20]:25" was not set up by me.

  • LinkedIn Woopsie with the Outlook 2010 Social Media Connector

    - by Martin Hinshelwood
    I have always used the LinkedIn toolbar for Outlook to sort out, upload and sync my contacts. Because of this I have over 2000 contacts in my contacts list that I sync with my phone, Plaxo, live, Google and others. I got a surprise the other day when my LinkedIn account was suspended and I was unable to login.   Figure: Bad, account suspended   So I contacted LinkedIn customer services to find out what the problem is, and here is the response: Dear Martin, We have recently noticed a large number of page searches and profile views through your LinkedIn account. We are aware that you may be using an automated or manual process to systematically view LinkedIn web pages. The information within LinkedIn is provided by our users for usage on the site only. In order to protect user privacy, our User Agreement prohibits using: 1. Automated or manual means to view an excessively high number of profiles or mini-profiles. 2.

We have placed a restriction on your account until you agree to stop using these or similar methods to view pages on LinkedIn. We look forward to your reply to discuss this further. Sincerely, LinkedIn Privacy Team It looks like LinkedIn has suspended my account because of something that their component is doing! I do not know if this is an isolated case, or if it will happen more as more users get on Outlook 2010 and update to the new software, but watch out. Has anyone else been suspended who has installed the Office 2010 RTM and the LinkedIn Add-On? Technorati Tags: Fail,LinkedIn,Outlook 2010

  • Mic not working when vga connector removed

    - by yygyt
    I have a computer that should run continuously without any connection to a monitor. For developmental purposes I have been keeping the vga connection with the monitor and experienced no problem until now. When I start the machine removing the vga connection beforehand, external microphone does not work. At first I didn't know anywhere to look and see the problem, but after a google search I saw that there is a command as alsamixer I ssh the machine end type alsamixer when it is connected to the monitor, here is the result If I remove monitor connection and reboot again, and then type alsamixer, I see the error, $ alsamixer cannot open mixer: No such file or directory I suspect that this error is related to X somehow. I really don't know anything about what goes beyond. This machine needs to work without any connection to a monitor. I would deeply appreciate any suggestions.

  • Has this server been compromised?

    - by Griffo
    A friend is running a VPS (CentOS) His business partner was the sysadmin but has left him high and dry to look after the system. So, I've been asked to help out in fixing an apparent spam problem. His IP address got blacklisted for unsolicited mail. I'm not sure where to look for a problem, but I started with netstat to see what open connections were running. It looks to me like he has remote hosts connected to his SMTP server. Here's the output: Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 78.153.208.195:imap 86-40-60-183-dynamic.:10029 ESTABLISHED tcp 0 0 78.153.208.195:imap 86-40-60-183-dynamic.:10010 ESTABLISHED tcp 0 1 78.153.208.195:35563 news.avanport.pt:smtp SYN_SENT tcp 0 0 78.153.208.195:35559 vip-us-br-mx.terra.com:smtp TIME_WAIT tcp 0 0 78.153.208.195:35560 vip-us-br-mx.terra.com:smtp TIME_WAIT tcp 1 1 78.153.208.195:imaps 86-40-60-183-dynamic.:11647 CLOSING tcp 1 1 78.153.208.195:imaps 86-40-60-183-dynamic.:11645 CLOSING tcp 0 0 78.153.208.195:35562 mx.a.locaweb.com.br:smtp TIME_WAIT tcp 0 0 78.153.208.195:35561 mx.a.locaweb.com.br:smtp TIME_WAIT tcp 0 0 78.153.208.195:imap 86-41-8-64-dynamic.b-:49446 ESTABLISHED Does this indicate that his server may be acting as an open relay? Mail should only be outgoing from localhost. Apologies for my lack of knowledge but I don't work on linux in my day job. EDIT: Here's some output from /var/log/maillog which looks like it may be the result of spam. If it appears to be the case to others, where should I look next to investigate a root cause? I put the server IP through www.checkor.com and it came back clean.

  • postfix 5.7.1 Relay access denied when sending mail with cron

    - by zensys
    Reluctant to ask because there is so much here about 'postfix relay access denied' but I cannot find my case: I use php (Zend Framework) to send emails outside my network using the Google mail server because I could not send mail outside my server (user: web). However when I sent out an email via cron (user: root, I believe), still using ZF, using the same mail config/credentials, I get the message: '5.7.1 Relay access denied' I guess I need to know one of two things: 1. How can I use the google smtp server from cron 2. What do I need to change in my config to send mail using my own server instead of google Though the answer to 2. is the more structural solution I assume, I am quite happy with an answer to 1. as well because I think Google is better at server maintaince (security/spam) than I am.

  • Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?!

    - by Ahmed
    Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?! As, I'm working on a website, which uses SAP .NET connector. I already added a reference for connector ddl, and while referencing its namespace "using namespace_name", or set class namespace to another one rather than connector namespace, I got error regarding connector classes with that error message "The type or namespace couldn't be found, are you missing a using directive or an assembly reference?". But while changing namespace name to connector namespace, everything is going well?! // Set namespace to be IDestinationConfiguration interface namespace. namespace SAP.Middleware.Connector { public class ConnectorConfiguration : IDestinationConfiguration { } } So, connector types forced me to set namespace of class to their namespace! Is this possible? If so, how?

  • how to protect telnet access to smtp port 25?

    - by Michael Mao
    Hi all: Please consider the following: 192-168-1-106:~ michael$ telnet <remote_server_ip> 25 Trying <remote_server_ip>... Connected to li*****.linode.com. Escape character is '^]'. 220 mindinscription.net ESMTP Postfix (Ubuntu) quit 221 2.0.0 Bye Connection closed by foreign host. Is this very bad? how to protect port 25 from malicious attackers? I've already set up a firewall, but not very sure what to do in this case. Basically I'd like to use this server to only send emails as alert messages, not receiving any external emails. Many thanks to the help in advance.

  • HTTP, HTTPS and FTP is not working but SMTP and IMAP are working.

    - by nWorx
    Yesterday on a computer of a friend a strange thing happened. after booting the ports fo http, https and ftp are closed but e-mail is still working. in the control panel the windows firewall seems active even if he tries to deactivate it. I have a suspision that it is the faul of norton internet security 2010, we have tried to uninstall it, but the uninstallation did not work. when using the removal tool from symantec it just goes to 23% and then it crashes. the process ccSvcHst.exe is still running. How can I safely remove the rest of Norton Internet Security? Edit: Norton Internet Security 2010 is sucesfully removed, but still no connectivity...

  • iRedMail home setup - use different SMTP relay for different destination domains

    - by John
    Hello helpful server folks, I'm messing with iRedMail. I've mostly been successful, I think I have an SMTP problem. I have changed RoundCube (webmail) to use BrightHouse's, my ISP's, SMTP server for outgoing. It works fine, I click send and poof, I have gmail. I can reply from gmail to my email server, and it works. It took 10 hours for the email to show up, which is a different problem, I think, but it does work. But when I send from my server TO my own server, my ISP's Postmaster account sends me a cryptic blurb. I just got off the phone with them, and they say it "should work", and that they can't reach my pop3 server. (pop3, pop3s, imap, and imaps are all open on my router and forwarded to the server, I'm not sure what I need, I'm just covering my bases...) pop3 and/or imap as external interfaces are just formalities, I really just want webmail to work. Roundcube only takes one SMTP server in its configs. How can I configure Postfix to relay / forward emails to my ISP's SMTP, while taking messages bound for my own domain and processing them? Since my ISP won't let me "bounce" my emails off of it. Maybe I'm vastly misunderstanding how e-mail works in general: To receive mail, I should only need port 25, SMTP, open to the internet, correct? Should I be concerned about some authentication failure from the outside to my relay? (My relay requires user/pass to use, my ISP's requires none.)

  • Postix transport smtp failover

    - by SimonJGreen
    We have a multi-tenant email relay set up that has a transport map file that looks like this: domain1.com smtp:mail.domain1.com domain2.com smtp:mail.domain2.com domain3.com smtp:mail.domain3.com [etc] In the event mail.domain1.com is down, email for domain1.com will be held by the postfix server until mail.domain1.com starts responding again. However we have a customer who has a backup DSL line on their site, an their email server is also available over this. How can I tell the transport to failover to a different host if the first is unavailable?
