If you are able to weed out illegitimate recipients, this may go a long
way to reduce spam, or at least it did for us. Looking the email
address up in LDAP is *much* cheaper than doing a call-out to the
backend server(s). Greylisting helps us, too, but seems to cost mail
from broken servers
Hello,
We are putting together an OpenBSD-based border email server to replace
an aging Linux box. On the current system, Postfix performs a call
ahead to two internal boxes for recipient validation. I'm interested in
recommendations on how to perform validation with the base sendmail.
