OT: Sendmail related...

[Alex Neuman]

Hi list,

I've been googling around and haven't been able to figure out *how* to look
for the following two things. Feel free to reply off-list if you think it's
not list-worthy material.

1. How do I change the "try to deliver for four days and then bounce back to
the sender" to, say, two days, when using sendmail?
2. Can I tell sendmail *not* to accept e-mail for domains that have no MX (I
know, "bad") or "no MX *and* no A" (not so bad) records in DNS? How about
with a milter?

The basic premise is that I've recently detected a surge in users that don't
seem to care about typos or that don't believe in address books. Mail gets
queued up and they don't have a clue until hours (or days) later that they
mistyped the domain name.
