Migrating to a new server and decided I would switch to postfix. On my old
qmail server, I used validrcptto to drop emails not destines for the
virtual accts on our site.
I've read tutorials and the backscatter/local recipient pages and my
postfix is still sending out bounce message instead of just dropping the
connections. I want to be a good netizen so want to nip this in the bud.
Here's my main.cf. Please let me know if there's more info you need.
