Can't get notifications using Exchange

[ayende@…]

I can't configure trac to use exchange as a server.

Well, I would say that as for any installation issue, you'd better first to ask for help in the MailingList or over #IRC.

Anyway, can you provide more information, as it's hard to help you with so few pieces of information.

• Does your Exchange server support SMTP inbound connections?
  • Did you try to connect to this server using a telnet connection on port SMTP (25)?
• Did you try to use TLS?
• What kind of error did you get (enable "debug" trace level in trac.ini file)

The error I get in trac.log using Exchange is:

2006-12-06 14:07:59,736 Trac[web_ui] ERROR: Failure sending notification on change to ticket #26: Connection unexpectedly closed
Traceback (most recent call last):

  File "C:\Python24\lib\smtplib.py", line 351, in getreply
    raise SMTPServerDisconnected("Connection unexpectedly closed")
SMTPServerDisconnected: Connection unexpectedly closed

I get it whether I set a username and password or not, whether I use TLS or not, whether I have the default domain set or not.

When I telnet to the exchange server and proper port, it seems that a connection is established, and then when you hit any key, it is dropped. The telnet log file has no data. Telnetting to port 80 on the server and hitting a bunch of keys results in an HTTP/1.1 bad request. (I'm sophisticated ;) )

I'll check with the Exchange admin to see if it accepts SMTP inbound connections. I don't know about TLS, but turning it in trac.ini on doesn't fix the issue.

Replying to anonymous:

I assume you meant port 25?

If you cannot at least type 'HELO' (or 'EHLO') and get a valid reply from the server, Trac will not be able to use this server. Maybe the connection is encrypted (SSL), in such a case the usual port is 465 (ssmtp), not 25. Be aware that Trac does not support SSL connections for now - whatever the port number.

Yeah it was connecting to port 25, not using an SSL connection, and the issue was resolved when the sysadmin adjusted some Exchange settings, though he didn't let me know what he did. Basically, Exchange was refusing my connection and he configured it to allow it then the Trac bits worked just fine. Prior to and after his adjustments my Outlook connected just fine, which made me unsure about the source of the problem. Thanks for your quick reply.
