Thks for the info. Yeah, I was sure there was going to be a
performance penalty, I was just trying to estimate the figures.

Our msg traffic will be _very_ light compared to what you guys have been
posting here -- we're talking about our laboratory only, which means a
couple of hundreds of people. So, I guess performance shouldn't be an
issue.

Yes, when it comes to complexity, sendmail is The King of Kings ;)
(I had to deal with it a couple of years ago) Thks for your input on
exim, we might give it a try on our test server to compare it with
postfix.

So far my _personal_ experience with postfix has been ok (nice docs,
simple configuration), although I cannot make any statement about its
performance under high loads. Also, we did have some (minor) issues
while trying to configure it to play with MailScanner. We still have a
showstopper issue, but we still haven't pinpointed the exact culprit
(check the post from Fabio Sobral on this ML a couple of days ago).

Best,

Andre
