<p class="MsoNormal">Note: I am NOT asking about aliasing of
INBOUND emails. I am asking about emails being sent OUTBOUND.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a need to send emails via different
internal email relay servers based on the return sender
associated with the email. Previously I did this in HP-UX
using sendmail’s “smarttable” facility.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We now need to replicate the setup on RHEL5
which also uses sendmail. I haven’t really had a chance to
look into it myself as I’m tasked with other priorities but
the co-worker that tried to do this last year and the new one
trying to do it now don’t seem to be getting anywhere in
replicating this.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The idea would be if I send an email and
set the return sender as say
<a moz-do-not-send="true" href="mailto:billybob@mydomain1.com">billybob@mydomain1.com</a>
it would relay through our MS Exchange server. On the other
hand if I set the return sender as
<a moz-do-not-send="true"
href="mailto:billybob@otherdomain.com">billybob@otherdomain.com</a>
it would relay through a separate Sendmail server I have for
that purpose. The difference here is that the Exchange
server and Sendmail both send their email via different
internet facing IPs.<o:p></o:p></p>

Sure, use Postfix instead<br>

Oh man, that's not fair ;-)<br>
<br>
look at the sender_dependent_relayhost_maps option in Postfix<br>
<br>
For a simple example, you could have something like<br>
<br>
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay_map<br>
<br>
in main.cf, and then in /etc/postfix/sender_relay_map you have
something like<br>
<br>
<a class="moz-txt-link-abbreviated" href="mailto:billybob@mydomain1.com">billybob@mydomain1.com</a> [exchange.server.com]:25<br>
<a class="moz-txt-link-abbreviated" href="mailto:billybob@otherdomain.com">billybob@otherdomain.com</a> [real.server.com]:25<br>
@mydomain2.com [other.server.com]:587<br>
<br>
(so <a class="moz-txt-link-abbreviated" href="mailto:billybob@mydomain1.com">billybob@mydomain1.com</a> relays through exchange.server.com port
25 and <a class="moz-txt-link-abbreviated" href="mailto:billybob@otherdomain.com">billybob@otherdomain.com</a> relays through real.server.com port
25, and all users @mydomain2.com relay through other.server.com port
587)<br>
