• Block by file type, but just file extension using MDaemon

  - by Arjun Rajagopalan

  I've had users sending copyrighted files (songs, videos) to each other over email. I blocked the file extensions .mp3 etc. What some users have done is to rename files to .doc etc. I cant block .doc etc filetypes because they are needed for day-to-day work. I'm using MDaemon 12 mailserver, Does anyone know how to make it block these attachments? I've been working on some content scanning for filetype code, but was wondering if there is a already made solution?

• Windows doesn't get access to internet though linux easily does

  - by flashnik

  We have a very interesting problem. The network is configured in this way: internet is connected to Trendnet switch TS DHCP server at 192.168.0.1 running on Ubuntu (S) is connected to internet switch DNS is also configured on 192.168.0.1 on S D-Link Wi-Fi boosters are connected to switch TS PCs use D-Link PCI-E Wi-Fi cards to get access to network PCs have both Ubuntu and Windows 7 There are about 40 PCs. When PC is booted to Ubuntu it easily gets access to internet. But when it's booted to Windows 7, it gets a valid IP-address, but doesn't get access to internet. The address, mask, DNS, GW-address are totally the same as when it's booted under Ubuntu. The S is reacheble and pingable. Sometimes when we are lucky the PC gets access to Internet, but after rebooting it can lose it. When PC under Windows has access, it has totally the same settings as when it doesn't. What can be done? UPDATE I shared a dropbox with 2 captures of traffic. Ping.pcap is a capture of pinging 8.8.8.8. And google-browser.pcap is a capture of opening a google.com in a browser, both of them are in tcpdump formats and made by Wireshark on Win PC. The MAC of Win PC ends on b7:63 and IP is 192.168.0.130. UPDATE2 This is ifconfig output from Ubuntu Server eth0 Link encap:Ethernet HWaddr 00:1e:67:13:d5:8d inet addr:193.200.211.74 Bcast:193.200.211.78 Mask:255.255.255.0 inet6 addr: fe80::21e:67ff:fe13:d58d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:196284 errors:0 dropped:44 overruns:0 frame:0 TX packets:190682 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:158032255 (158.0 MB) TX bytes:156441225 (156.4 MB) Interrupt:19 Memory:c1400000-c1420000 eth0:2 Link encap:Ethernet HWaddr 00:1e:67:13:d5:8d inet addr:192.168.0.1 Bcast:192.168.0.254 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:19 Memory:c1400000-c1420000 eth1 Link encap:Ethernet HWaddr 00:1e:67:13:d5:8c UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:16 Memory:c1300000-c1320000 nslookup from Win results in DNS request timeout, nbtstat in 'not found'.

• Postfix sending mail back to itself? (Ubuntu 9.10)

  - by webo

  I setup Dovecot and Postfix using the "Dovecot-Postfix" package with SASL and all that. The Dovecot part seems to be working fine but I'm having issues with Postfix. Whenever I send a message to another address through the postfix server, two things happen. the message never gets to the other address (even when I request a delivery notification, it says that it's been delivered but it's not in the spam box in the other inbox or anything) The message comes back to my inbox through Dovecot as though I sent it to myself internally. e.g. I send an email through my postfix server to my gmail account, 10 minutes later nothing shows up in my gmail account but the message comes back to me as though I was sending it to my internal address (with no errors) Any ideas?

• Clipboard app that automatically saves to Web share folder ?

  - by cyberpine

  I currently use SnagIt and have used Windows 7 Snipping tools. These tools allow you to copy a piece of your screen the clipboard and then paste it into other applications on your desktop. They work with Outlook and it's really useful as you don't have to save the image to do a write-up or send an email. Problem is - you can't paste clipboard images into webforms. Gmail web does have image insert feature, but it only works on web images that you copied as it extracts the full url from your copy and uses that. It does not work on with images in your local clipboard. Does anybody know of an application that would allow to clip and save directly to a web folder, maybe something that replaces your clipboard with the URL of the save image location? It would be awesome if the picasa web client or evernote allowed actual clipboard pasting. Instead they ask for a file to upload.

• Blocked port 25 on Windows 7 64 bit

  - by Michal Gow

  Strange problem. I have 2 computers connected to Wifi router. One with Windows Vista & second with 2 operating systems: SUSe Linux and Windows 7 64bit on it. Computer with Vista can connect to SMTP server of my email provider (and any other) using port 25, and can connect to a mail server using telnet mail.server.com 25 if this port is open. Computer with dual operating system can (using Linux) do the same. The same computer, with the same hardware (Wifi card etc.), and using the same WiFi router, cannot however use Port 25 and cannot Telnet into any smtp server. So the problem is in Windows 7. I did uninstall all antivirus software and disabled the firewall. The problem is still here. Is there way how find out which software is blocking this port?

• Cannot view dates of emails(no date field), in my CSV file exported from MS Outlook

  - by barlop

  I am using Outlook 2010 - I have my emails showing in there. and exported my emails, into a csv file. (file..options..advanced...export..export to a file.. I have opened that csv file in excel Here is a list of the fields it shows. I see "Date" doesn't appear among them. Subject Body From: (Name) From: (Address) From: (Type) To: (Name) To: (Address) To: (Type) CC: (Name) CC: (Address) CC: (Type) BCC: (Name) BCC: (Address) BCC: (Type) Billing Information Categories Importance Mileage Sensitivity Any idea why "Date" isn't included, and how to include it? Also, (and less importantly, and as a very secondary issue) is there a convenient way to read the csv file? reading an email with a long body, in excel, is not convenient, I need to select all of the body from the cell and copy/paste it into notepad.

• Enter / Return key stops working

  - by andygrunt

  I have a Dell Latitude E5400 laptop running Windows 7. Everything runs fine on it for days then I suddenly notice the enter/return key is no longer working e.g. I could be writing an email, press enter for a new line but it doesn’t ‘register’ – so no new line. I thought it might be some dirt under the key perhaps so I tried running the Windows onscreen keyboard but the Enter key on that doesn’t work either. A reboot always fixes the problem but it’s a pain. Any ideas a) how to fix it and b) out of interest, is there some other key combination that I can use as an alternative to using the Enter key when I need to? UPDATE: Thanks to CarlF's suggestion, I tried exiting running programmes and found it seems to be a problem with PhraseExpress.

• Configuring sendmail to use one outbound MTA exclusively

  - by Charlie Martin

  I have a sendmail problem, and I'm anything but a sendmail guru -- I could use some help. My problem is that I have a system intended to be more or less an "appliance" -- it's not intended to have an admin. Because of this, it needs to be able to "call home" by sending email. As we have configured it, this works fine -- using sendmail, it finds the appropriate relay by looking up an MX record and everything works fine. Now, however, because of security concerns, we want to limit it to using exactly one relay, so for example relay.corp.example.com. Should the user configure it to use, say, fubar.example.com, the mail sending should fail or be deferred. I thought that by configuring sendmail with a /etc/mail/server.switch file containing hosts files without dns, I'd get that effect. This doesn't work -- instead, if it gets mail addressed to [email protected], it tries to talk directly to example.com, and ignores the configured server. Any ideas?

• Drag and drop to attachments feature only working intermittently in Outlook 2010

  - by Jared275

  I've been trying to troubleshoot a problem with my Outlook 2010 install where the ability to drag and drop an attachment into a new email will stop working from time to time. It seems to be fairly moonphase-y in that I can't seem to find a correlation in what causes it to stop working. Some searching online lead me to try running this command through the windows run dialogue: Regsvr32 ole32.dll, which apparently re-registers that particular dll as a command component in the registry. It didn't work, but I was curious as to why it was a suggested fix, and if there was something similar to try that would work, or another known solution.

• How to reliably run a batch job every 5 seconds?

  - by Benjamin

  I'm building an application where the sending of all notifications (email, SMS, fax) will be asynchronous. The application will write the notifications to the database, and a batch job will read these notifications and send them with the appropriate transport. I was first reading at ways to run cron faster than the minute, and realized this was a bad idea. The batch scripts are written in PHP, and I guess that writing a proper daemon would be quite an overhead (though I'm open to any suggestion, as PHP car run indefinitely as well). What I have in mind is a solution that would: Run the PHP script every 5 seconds Check that the previous run has finished, or abort (never 2 concurrent batches running) Kill the script if live for more than x minutes (a security in case it hangs) Start with the system (if a reboot occurs) Any idea how to do this?

• Blackberry Access to Powered Down Exchange

  - by Sam Cogan

  I work with a company (it's more of a charity really) who have a single Exchange Server, with a few Blackberry users, who download emails via POP3 or IMAP. They are in a developing country and so every night they turn off the Exchange server to save power. However, they now want the Blackberry users to be able to get mail at night. They have a Linux server (a rented VPS), so they are considering having the mail delivered here and then pulling this mail via a POP connector into Exchange. Therefore at night, the BES users (who will now be pulling their POP email from the Linux server) can still get their mail. Can anyone think of a better solution to this problem that I may have missed? Unfortunately there is no convincing the company to leave the machine on overnight.

• Will USMT 4.0 in MDT 2010 Move/Migrate the .NK2 File for Outlook?

  - by Mitch

  We're about to begin a refresh project for about 100 XP Pro laptops and have a concern with regards to the .NK2 file which holds cached email addresses(?). If possible we'd like to have USMT move/migrate this but I can't find anything that confirms that this happens automatically or has been done before. I see lots of manual processes but at this point I'm not sure that we can use that. Has anyone done this or seen this done? Perhaps you can point me to a resource that can give me an idea how its done? Any information would be appreciated. USMT seems to get a lot of the details but missing this part seems odd. Thanks in advance for any responses.

• Bind is updating DNS with wrong resolver info after rndc flush expires

  - by RussH

  I'm running Bind 9 on a small office server (Centos 5) with a local mailserver. There's a domain we need to email - it shows wrong DNS info for the MX servers using the local bind, so an RNDC flush updates this correctly - but then, after some time - it reverts back to the wrong resolver. I would have thought that 'rndc flush' just clears the local cache and pulls all the authoritative info down - so why is it being overwritten (by what seems like the next update)? where do I need to look? Presumably there's some named logging(?) to determine where it's getting the [new or cached] updates from?

• How to calculate required switch speed based on network usage?

  - by tobefound

  I have a 48 port HP Procurve Switch 2610 (J9088A) that can handle 13.0 million PPS (packets per second) and features wire speed switching capacity at 17.6Gbps. First off, what does that REALLY mean? Where do I start when trying to figure out if my office (with 70 employees) will be well setup with this switch? How to calculate through-put based on a user average load of X MB per day? 90% of the folks will only be sending email, access random websites, etc... the other 10% will be conducting heavier tasks like moving image files (10 MB) across network shares, constant external FTP streams through the switch to a server etc... Is this switch good enough?

• BES 5.x issues when connecting to Exchange 2010 SP2 RU4

  - by makerofthings7

  Ever since we updated from SP1 RU4 to SP2 RU4 we have noticed that our BES devices will simply stop receiving email. This has occurred at least 5 times in the past few weeks. Today, while speaking with RIM support (a T3 contract), they said that they have reports of sporadic connectivity issues from some BES users. This has been occurring with Exchange 2010 SP2 RU4, and have no public information to give us. We were able to temporarily get things running by doing any or all of the following Restart the BES server Recreate the MAPI profile (deleted the keys in the registry) Restart the CAS servers Wait it out (2 hours) What other options should I take to resolve this issue?

• Microsoft Outlook 2007 - General Failure. The URL was: "<http:/something.com>". The parameter is incorrect

  - by Simon Peverett

  For the last two days, Outlook has decided it doesn't like URL's. Any email message that comes in containing an URL will show the following in an error dialogue message box when I click on the link: General Failure. The URL was: "http:/something.com/somewhere/". The parameter is incorrect If I copy the link into a browser, it works correctly. OS is Windows XP SP 3, Microsoft Office 2007 (Outlook), Internet Explorer 8 (also Chrome). I have, of course, Googled this and the two most popular solutions are: Solution 1: Add/Remove programs Set Program Access and Defaults Custom tab Make sure a default browser is selected Solution 2: Add/Remove Programs Select the MS Office 2007 item Click Change Click Repair I have tried both of these and I still get the problem. Has anyone else had this problem and solved it with a solution other than those listed above?

• china and gmail attachs -

  - by doug

  "We have evidence to suggest that a primary goal of the attackers was accessing the Gmail accounts of Chinese human rights activists. Based on our investigation to date we believe their attack did not achieve that objective. Only two Gmail accounts appear to have been accessed, and that activity was limited to account information (such as the date the account was created) and subject line, rather than the content of emails themselves.” [source] I don't know much about how internet works, but as long the chines gov has access to the chines internet providers servers, why do they need to hack gmail accounts? I assume that i don't understand how submitting/writing a message(from user to gmail servers) works, in order to be sent later to the other email address. Who can tell me how submitting a message to a web form works?

• postfix: force server to send mail outside of localhost

  - by LoneWolfPR

  I have a php file that sends mail using the mail() function. The problem is one of the forms sends to a domain that is registerred on my server while having the mail handled on a different server. Postfix looks locally only. When it doesn't find the email address is rejects the message. How can I configure postfix to send mail to all domains through the internet and not locally? Update Ok. So it wasn't a postfix issue at all. I simply needed to turn off mail to that domain from the command line. For anyone that needs that command it is (at least on my system): /usr/local/psa/bin/domain --update example.com -mail_service false

• Is there an easily configurable way to inject data into IIS 6 SMTP logs?

  - by Lorcan O'Neill

  I am using IIS 6 SMTP server to send out some mail on our behalf. I am also storing each message we send in a SQL table - with a UUID representing each message. I would like to be able to inject additional data into the SMTP logs located in SMTPSVC1 - an additional field which would contain this UUID in the event of a RCPT cs-method call. This is so that I can check a one-to-one relationship between messages sent in SQL and messages actually sent through SMTP. If possible, I would like to avoid writing a C++ custom logger as some sites I've viewed have suggested. Is there an easily configurable way to inject this data into IIS 6 logs? Even if it was only the ability to perform a regex on the data/headers of the outgoing email, that would be enough. Thanks!

• Long lag and errors clicking gmail links in google chrome

  - by Doug T.

  I recently downloaded Google Chrome with Ubuntu 9.04 and love it. Ironically one site I consistently have issues with is gmail. When I enter gmail I will click a link, say an email or the inbox link. After a very long wait (on the order of 30 seconds to a couple of minutes) my page will load with an error such as: Some Gmail features have failed to load due to an Internet connectivity problem. If this problem persists, try reloading the page, using the older version, or using basic HTML mode. Learn More. Googling the symptoms has not helped. Has anyone else had any similar issues? Has anything helped?

• Windows script to create directories of 3,000 files

  - by uhpl1

  We have some email archiving that is dumping all the emails into a directory. Because of some performance reasons with the server, I want to setup an automated task that will run a script once a day and if there is more than 3,000 (or whatever number) of files in the main directory, create a new directory with the date and move all the main directory files into it. I'm sure someone has already written something similar, so if anyone could point me at it that would be great. Batch file or Powershell would both be fine.

• Lost support for Web Access on Verizon BlackBerry World Edition

  - by Jimsmithkka

  Hello all, I believe that some silliness has occurred with my blackberry after a OS upgrade. I have 2010 Blackberry world edition phone, purchased off a friend who went iPhone, that at first worked with web on the Verizon network. When i connected it to my PC to transfer contacts, it prompted for an OS upgrade, which I performed. Post-Upgrade I have found that i can no longer access any of the web services: eg. AppWorld, Email, Twitter, Browser. And they all state that i need to upgrade my account to gain access. I had a Storm previous to this that worked fine, and at the VZ store they told me this device is no longer supported (new in 2010 though), and they got me a free "upgrade" to the Blackberry flip. What i could use help with is finding a source stating it is discontinued or a guide that will help me re-enable the web features. I can provide further info later if needed (currently at work with the flip, the WorldEdition is at home).

• Mail sent from local Postfix marked as "possible phishing" in Outlook

  - by leo grrr

  Hi folks, Sorry for the newbie question--this is not my area of expertise by a long shot. I work at a small development shop and we finally got around to doing code reviews. (Yay!) I set up an instance of Review Board -- an open-source code review tool -- on one of our local servers but it doesn't seem to like talking to our hosted Exchange server to send notification emails. I decided to just install Postfix on that same box and send mail from localhost, which is working much more reliably, but Outlook disables all links in the email announcements and marks it as possible phishing. What is making these emails look suspicious and what can I change? Would the best thing be to figure out how to relay to Exchange from Postfix? Thanks!

• Multiple SMTP servers in Thunderbird3

  - by ldigas

  Situation: 2 mail accounts - each with its own pop3 and smtp servers, accesed normally. Except, when using Vodafone mobile network (you know, those usb or pcmcia cards ...) in which case mails are send using Vodafone's SMTP server. I configured both accounts in thunderbird for their default servers, and then added under multiple identities, another called Name of User (mobile) for each account. And it works. Except, I don't like the fact that when I send mail using mobile smtp server it sends them under Name of User (mobile) <-- the mobile part being important. I could of course, delete that part, but then when sending mail, I'd have no way of differenting between the two. They'd both look as Name of User email@address_of_user.com. So, what would be the easiest way to solve this ? It is not a major problem, but it is annoying.

• How do I start Chrome using a specified "user profile"?

  - by Danny Tuppeny

  I use the new built-in "Users" feature of Chrome to switch between Home/Work accounts easily. However, Chrome remembers the "last" user profile you had selected when launching new windows. This is a problem if I close down my "Home" profile last, because when I then click the Email shortcut on my taskbar, because it goes to mail.mycompany.com using my Home profile, and I'm not logged in. I'd like to change the shortcut to the company webmail to pass a switch that tells Chrome to always start as the "Default" user, regardless of the last one used. Note: I have tried user-data-dir, and this seems to do something very different, completely isolated from the Users functionality built in to Chrome. It's possible I'm using it wrong, but please test this before assuming it does the same thing and posting an answer ;-)
