"Asymmetrical" mail processing with RT

RT Users

Sorry, I couldn’t think of a better Subject: line.

Here’s the situation. Due to limitations on the way mail is set up around
here, I need to set up RT as follows:

  • Outgoing mail is sent to an external SMTP server for delivery
  • Incoming mail is retrieved via POP3 from an Exchange Server 5.5 mailbox

Is this possible? I’ve been through the wiki docs, but it’s awfully sparse
on mail configuration. I’m using exim4 as the MTA and probably fetchmail to
grab the incoming mail.

totally acceptable… Just forget the POP3 bit… you want to use
Fetchmail to retrieve the mail for RT from the POP3 box and then
redistribute it into the mailgate program.

So your setup is all cool… just you need to look up the Fetchmail stuff…

You’ll need to set that up in Exim. Can’t help you there, as I use postfix.

I do this with an ISP account used as a maildrop. Fetchmail grabs it
from the ISP, then dumps it to local users.

Take a lookie at a Quick how-to I posted on docs.opengroupware.org.
http://docs.opengroupware.org/Members/mkbrown/SOHO/UsingISPmail/document_view

Basically, you’ll need to use the real RT set-up instructions, then get
fetchmail to pull the various e-mail accounts and dump them to your MTA.

Now, if you have any spam filtering set-up, AND you use +addressing for
spam delivery (johndoe+spam@domain.ca), then you might want to go beyond
just putting the RT aliases in the aliases file.

Here’s what I did to do that:
/etc/aliases

spam catching for rt

info+spam: spam
general+spam: spam
training+spam: spam
support+spam: spam
business+spam: spam
sales+spam: spam
consulting+spam: spam

spam: realadminuser

info: “|/usr/bin/rt-mailgate --queue General --action correspond --url
http://localhost/rt/”

and so on… It helps keep out some of the spam.

I’m on Debian sarge, RT 3.2 and Apache 2 with Postfix, Fetchmail and
Cyrus IMAP

Hope it helps!
