[ale] Relaying email OUT based on return sender domain

[Lightner, Jeff]

Note:  I am NOT asking about aliasing of INBOUND emails.  I am asking about emails being sent OUTBOUND.

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.

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.

The idea would be if I send an email and set the return sender as say billybob at mydomain1.com<mailto:billybob at mydomain1.com> it would relay through our MS Exchange server.  On the other hand if I set the return sender as billybob at otherdomain.com<mailto:billybob at otherdomain.com> 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.

Does anyone know how to do this in Linux Sendmail successfully?   Is there a better way to do it these days in sendmail?   I setup the UNIX stuff around 2006 and its been working ever since.   Maybe by use of a milter?

Please don’t suggest we move to Postfix unless you know how to accomplish the task described above in Postfix.
