Reject emails to nonexistent addresses?

[nats]

I agreed to Steve Swaney, milters for sendmail are very handy tools. I have
it running for a year now, and it works like a charm together with
MailScanner and Sendmail.

Milter-ahead checks to see if the email can be delivered to the recipient
before sendmail accepts the message for delivery. Not normally needed on a
mailhub but very useful on a pass-through gateway.

Milter-sender attempts to verify that the sender's email address is in good
standing by performing an SMTP callback to the MX server responsible for the
sender's domain.

Both are handy tools.

There are many more useful milters available at

Another one I'm about to test is

milter-limit limits the number of messages by connecting client IP, from a
sender, or to a recipient over a given time period.
