OT: Sendmail related...

[Rick Cooper]

I have done this for years and believe it or not there are still users that
don't get it and keep trying. To be fair however, outlook(express) doesn't
always return the actual error text from the MTA so they often end up
calling me and I look at the log and tell them to fix or verify the address.
The place you get into trouble is when the misspelled domain exists, but
doesn't accept mail, in which case you still end of with mail in a retry
status. Of course I have a process that checks for mail in a retry state
every 15 min and send me an email when there is something waiting.

Talking to myself here, just found one of the two things I was talking
about.

There's a milter called milter-chkrcpt (found using milter.org) that does a
"call ahead" and rejects the e-mail if there are no valid recipients. I'll
give it a shot.

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.
