I recommend the following for MTA gateway duties based on the SMTP protocol:

MTA: Postfix (
OS: FreeBSD ( or
Log analyzer:
Hardware: Pentium 100 or greater 64MB of RAM, at least 2GB of free
space, could EASILY handle your loads.

The ultimate SMTP gateway, in my mind. Did I mention it was all "free".

Let me know if you are considering this configuration, and I can offer
some tips.
