What I'm going to do in my case with a back to back is to implement both
Linux with SendMail and UNIX with Postfix.
I'll have each of them forward for different domains. Since I'm hosting
different sites.  Just want to experiment.
I'm a developer so it doesn't matter what I program with!  I have Sun's,
SGI's and of course I386 type of machines and
I want to learn how to configure them all to work together in a secure
situation.  So, I'm always trying something new with
The configurations etc.

Thanks everyone for the answers.  I'll use an ULTRA 5 with a SUN PCI
card in it for my filters in the DMZ.  I just got snort running on an
old ultra sparc 5 and that was fun.  Different systems can work
together.

Joseph

If using Windows is preferred, then it's also worth to try out MS IIS
SMTP service as mail forwarders. The one shipped with W2K & W2K3 should
be enough I think, since even MS-Exchange 2k/2k3 uses them for SMTP. It
also had well-defined interface for filtering, adding disclaimer, that
can easily be implemented in a .vbs script ( I wrote one free VB COM dll
filter for IIS SMTP service).

If it's to be a Unix box, then I'll choose Postfix for security, out of
the box features, and much else. The OS might better to be one of the
BSD (instead of .. you know ..). Sendmail will always be my last choice,
again, for security reason.
