<html><head></head><body bgcolor="#FFFFFF"><div>Wes,</div><div><br></div><div>I would let your current outside accessible mail server stay that way and do the configuration to move mail from your sendmail to RT and from RT to sendmail. There are a lot of reasons:</div><div><br></div><div>1. Simplifies the management of your firewall rules and forensic analysis of something happens. </div><div><br></div><div>2. Simplifies your patch management on Internet accessible mail servers. </div><div><br></div><div>3. If you stop managing the mail environment it is still very easy to manage. I.e. you won't have the new mail administrator messing with your RY server. </div><div><br></div><div>4. It's relatively easy and it is documented how to setup a mailgate alias on your sendmail server for getting emails into RT. so you are only really worrying about outbound mail using a local sendmail on your RT server. </div><div><br></div><div>Honestly the list goes on. After using RT for a very long time and sendmail for a good 10 years and managing security for many enterprises, it's the only way I would go. </div><div><br></div><div>Mike<br><br>Sent from my iPhone</div><div><br>On Oct 25, 2011, at 2:59 PM, Wes Modes <<a href="mailto:wmodes@ucsc.edu">wmodes@ucsc.edu</a>> wrote:<br><br></div><div></div><blockquote type="cite"><div>

I'm pretty sure this has been hashed and rehashed on this list, but
a google search this morning turned up nothing definitive, so I will
ask:<br>
<br>
I am reconfiguring a twisted RT installation (3.6, but moving toward
4.0). We already have a mail server (sendmail) running on another
server. <br>
<p>For incoming and outgoing email I thought of three differrent
options:</p>
<ul>
<li><strong>OPTION A: Re-addressed</strong><br>
Incoming mail comes into the mail server and is readdressed to
RT server and forwarded<br>
Outgoing mail coming from the RT server goes to the mail server
and is readdressed before going out to the world<br>
Pro: one mail server to admin; Con: pain to set up, <br>
</li>
<li><strong>OPTION B: Redirect</strong><br>
Incoming mail comes into the mail server and is redirected to
the RT server<br>
Outgoing mail coming from the RT server goes to the mail server
and is redirected to the rest of the world<br>
Pro: one mail server, simpler to set up; Con: less of a setup
pain, but still<br>
</li>
<li><strong>OPTION C: Direct</strong><br>
Incoming mail goes straight to the RT server<br>
Outgoing mail coming from the RT server goes out to the world
directly<br>
Pro: Simple to set up; Con: two mail servers to deal with<br>
</li>
</ul>
What is the best practice (or failing that, Most Common Practice)
among RT administrators?<br>
