I just moved from FC2 to FC3 and I think I have my mail sendmail config

just as it was for FC2. Sendmail receives mail for local delivery just fine, but outgoing mail does not send.

I use my ISPs SMTP server as a smart host. In sendmail.mc:


define(`SMART_HOST',`relay.plus.net')


'mailq' shows a bunch of mail not being sent due to host name lookup failures:



iACC9XnN003813* 6874 Fri Nov 12 12:14 MAILER-DAEMON
(Deferred: Name server: relay.plus.net: host name lookup fail)
<accounts@xxxxxxxxxxxxxxxx>
iACB9XVo003702 8287 Fri Nov 12 11:12 MAILER-DAEMON
(Deferred: Name server: relay.plus.net: host name lookup fail)



It might also be worth trying:

define(`SMART_HOST',`relay:[relay.plus.net]')

Paul.


It works! Thanks so much.

why does it work though? what does the relay:[] thing do?
