They tell me I'm posting too much.  Is the quality suffering?

In article <24782@uunet.UU.NET> dsc@izimbra.CSS.GOV (where was george?) writes:
# ah, the old what's a poor internet host that handles pathalias output

# server for.

That's one option.  I do this in my IDA-style sendmail.cf by resolving to
SMTP if and only if an MX or A record is found with $[...$].  I search a
database of UUCP exceptions just prior to this, so people I have a local or
Telebit UUCP connection to are gone before $[...$] is run.

If $[...$] doesn't work, I check the pathalias database.

All in sendmail.  No extra forks.
