sendmail blues

Hi all, I've an unusual (for me) problem:

- I'm running RHEL release 3 (taroon). I know, I know. Nothing I can do - it's the application 
vendor's requirement.
- This application also MUST have some Sun MTA installed and running, even if we don't use it - and 
we don't. This MTA sits on ports SMTP, SSMTP, IMAP and POP, HTTP and HTTPS and provides services to 
the application only, NOT TO THE OS.
- We still need to be able to mail admin stuff such as logwatch and others. RedHat comes with 
sendmail and we are trying to keep this box as close as possible to default configuration.
- The sendmail queue runner by itself is not enough because I can't find a way to make it expand 
aliases - root messages end up going to [email protected], which is not where I want them to go.
- Sendmail won't start because the silly Sun app is squatting on port 25.
- If I use DaemonPortOptions to tell sendmail to listen on a different port then I get sendmail to 
start but I haven't found a way to make the queue runner send to that port on localhost. The runner 
ends up connecting to port 25, which is the Sun MTA, who proceeds to deny the connection.

Does anybody know how to do one of the following:

- make the sendmail queue runner expand aliases
- make the queue runner send to a port other than 25
- make sendmail behave like in the good old days and forgo the need for the queue runner

Some options that have crossed my mind but which I'm trying to avoid:

- redirect port 25 using iptables
- modify sendmail's source and recompile (ugh)
- give up on sendmail and install exim or postfix or something that can be understood by someone who 
hasn't read the Bat Book in the last 6 years and who is not particularly inclined to read it again.

Any other ideas?

TIA

Yuri
