Beyond translating configuration, there's one important part of Postfix that has no Sendmail equivalent: the postscreen front-line SMTP screener program. Postscreen implements a greeting pause, weighted parallel DNSBL checking, and optionally a few other spambot-detection tactics. Because it is a unique tool, some distributions do not enable it by default. Make sure you have it set up, because it is an extremely effective and lightweight tool.
Bill: Can you please explain that tool? TIA, -Ramon
