[TriLUG] Sendmail error: SYSERR: putoutmsg

[Andrew Perrin]

Jeff, I don't know sendmail at all, but this line:

> tcp        0      0 127.0.0.1:25            0.0.0.0:*          LISTEN

shows that it's listening on the loopback port (127.0.0.1) but NOT on any
external port. That's your problem -- somewhere or other sendmail is
deciding to listen only on localhost. Is there an option for making it an
SMTP server for outside requests?
