Re: Having some problems with a FreeBSD mail server (SMTP)

They can all log in and receive e-mail POP3. I'm using TLS and SMTP AUTH with sendmail - all my users are on Microsoft Outlook 2003 (bar one on Thunderbird and me on KMail). Outlook didn't do TLS properly until Outlook 2003 Service Pack 2 or 3 - the symptom was repeated timeouts on trying to send mail. Even after upgrading all the users to SP3, we still occasionally have a similar problem. A user will try to send mail, the TLS negotiation will time out, and from that point on mail will just accumulate in the outbox. Outlook has to be closed down and restarted before it will correctly try the TLS connection again. We also encountered another issue, which may or may not be related to using a Windows AD domain, which was that Outlook will reuse message-IDs - generally by copying the message-ID of an original message and using it as the message-ID for the reply. This one bit me twice: once when a user (quite correctly) complained that she was losing email. On investigation, it turned out that her manager had sent three or four different messages in reply to messages of hers, and Cyrus imapd had binned them all as duplicates based on the copied message-ID. I had to switch off duplicate suppression in imapd. The second time - which I haven't found a solution for - is in Mailman. The HTML pages for archives are built using the assumption that message-IDs are unique: the result is that when two messages have the same message-ID, only one of them will appear in the archive. (Which one is random, so I suspect Mailman is using the message ID as a hash key internally). I get the feeling that Microsoft pay lip-service to the standards, but don't really carry out proper testing against anything other than Microsoft Exchange (after all, why would you use anything else?!). Outlook doesn't support IMAP well. Worst, from my point of view, I have regular complaints that people using POP3 are losing email. By using telemetry in Cyrus imapd, I've been able to establish that there's no problem server-side: Outlook is downloading the mail, and then throwing it away. Try telling a user that Microsoft stuffed up, though. (Sorry - this turned into an Outlook rant. I hope you find some benefit in the early paragraphs, before I started frothing at the mouth and throwing my toys).

Have you even tried to get them to telnet to port 25, 465(for tls/ssl) to see what happens? If their ISP is blocking port 25 then you can get them to send their mail using port 465 (with TLS/SSL) or using the SMTP submission port which is on port 587.

RE: Having some problems with a FreeBSD mail server (SMTP)
-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Falanga I run a mail server for my church. Today I was called that folks are able to receive, but not send their mail. They are all currently configured for POP3 (I use dovecot). At home I tried to send mail to two different e-mail accounts of mine using the church e-mail server and was successful. I used KMail for this. As I look through /var/log/maillog I do not even see authid=their_user_ids in the mail log (I'm using TLS with sendmail). One of the pastor's told me the error he's seeing is timeout. They are using Outlook, I'm not sure of the version. What problems do people here usually encounter with Outlook mail clients and their SMTP servers? [EMAIL PROTECTED] Andrew: I've seen a similar problem from time to time with Outlook 2003 clients. For seemingly no reason whatsoever, they give a timeout sending mail. Googling the error code throws up many with the same error and no solution that I've found. Telneting to port 25 or even running the Outlook test mail account feature still work, while Outlook comlains it can't send. The workaround is to quit Outlook and start again. By quitting Outlook, the user must choose 'exit' from the 'file' menu. Simply closing the close box still leaves Outlook in memory and the problem remains. The problem seems to happen perhaps once or twice a month for some users.

A couple of you replied that they've seen issues with this and resolved them by closing down Outlook, by the File -- Exit method rather than the X in the upper right. I'm really beginning to suspect this because the pastor I was working with told me that our senior pastor explained to him that he could send from a particular coffee shop in town when he couldn't from church. Though I can't personally see a down side to having an office in a Starbucks (I don't know the name of the actual shop they were in), I think that the Outlook client get's some bad stuff in the cache that is flushed out when they shutdown their computers to go make the journey. The pastor I was dealing with said he went there and all of this mail sent without a hitch. The other possibility is that the ISP is blocking some particular port. We did just change ISP's within the last 2 weeks and according to this pastor, these sending problems originated at that time. We'll see.

They can all log in and receive e-mail POP3. Thanks, Andy Andy, These errors can be some of the hardest to track down. I would go to one of the problem users and try sending email with their client as you watch the maillog from a ssh window. Outlook and Outlook express send mail a bit differently so you will need to know which client they are using. Also, if sending mail was working, and just stopped, I'd suspect some microsoft patch as the culprit. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
