I'd disagree with both your assessment of sendmail. It took about an hour to configure 4 OpenBSD systems to route mail for about 12 domains, and include both whitelist and blacklist entries for addresses and servers. Its also easy to set to run in a protected shell environment.
Qmail isn't all that much easier to configure. Either way, if you don't understand DNS, and I mean REALLY understand DNS with respect to mail flow, neither will work correctly. -------------------------------------------------------------- Roger D.
