This is do-able with sendmail. Just about anything is do-able with
sendmail. [Write a ruleset that implements a Turing machine and take
it from there...]

Gosh, you really are misinformed. sendmail's been routing mail on the
internet for around 20 years now. The software is at the forefront of
new standards and functionality. Because of its installed base, a mail
standard won't happen on the Internet unless it gets implemented by
sendmail.

That's because the protection model on UNIX systems makes it much
harder to write and deploy a virus.

I doubt it. AFAIK there have been no documented instances of a UNIX
virus. [Well the folk at Bell Labs played with them ~10 years ago and
then there was the Internet worm in 1998, but that wan't a virus.]
This doesn't mean these things couldn't exist. It's just nobody's come
across a real example of one yet.

    Paul> Does it still ring true " You get what you pay for"????.

I have no idea what you mean by this or what you're getting at. Are
you saying that the only worthwhile software is the stuff you pay for?
FYI, most of the critical networking software on the internet is Open
Source and free: BIND (DNS), sendmail (mail), Apache (www). The
internet wouldn't be what it is without those things.
