Newbie Alert (Mail settings)


#1

I have rt on a test server right now. I’d rather learn it and mess it up
there before it goes prime time. One thing I noticed is due to my paranoid
way of running the servers. (ISP) I only allow 2 of our 24 servers to run a
mail server. One is sendmail running as a Daemon and handles a few thousand
users, and the others is NT based. When one of the servers needs to send
something via email (like logcheck reports of portsentry etc) it just
executes sendmail sends it’s stuff and unloads. (Sendmail is a bear to make
relay proof, and one is enough to keep on eye on) I realize (I think!) that
RT will actually need to receive email, not just send it. This occurred to
me when one of the guys testing it asked why he kept getting a 'server
unavailable will keep retrying every 4 hours for the next 5 days in his
mailbox every 4 hours from some dude named ‘rt.’ ;–)
I still won’t run sendmail as a daemon, but have considered setting up
either a semaphore or just running sendmail ever 155 minutes as a cronjob to
send and receive anything waiting on it. Is that a problem, or what does
anyone else do, who is not allowing sendmail (or some other email software0
to run as a full time daemon?
I guess I am referring specifically to people whose servers are live on the
internet 24 hours a day and have to deal with RBL, orbs etc and keep the
spammers away from there machines.

Thanks, and please excuse me if I sound like I am clueless. (See subject)

Could you just run fetchmail on your RT server every N minutes?On Fri, Dec 01, 2000 at 08:44:14PM -0500, Bruce D. Meyer wrote:

Actually, newer versions of sendmail are relay proof by default.
But I agree that machines which don't need to be running an SMTP
listener should not be doing so; my usual method of dealing with
this is to run it without the -bd flag, so that it will still
flush the queue periodically.

Another option is to configure your firewall so that port 25
connections from the outside are only allowed to the machines
that you want to receive mail on.  All depends on whether you
trust your sysadmins or your firewall admin more.  *grin*

I think the RT FAQ includes info on how to use fetchmail to
pull mail in from a POP or IMAP account on another box.  Should
work pretty well.
