Disable 'domain of sender address does not resolve"

[dpuryear]

I would like to disable the mail_check "Disable 'domain of sender address does not resolve". I've done this in /etc/mail/sendmail.cf (actually, via sendmail.mc then I compiled via m4 and ran omsendin, and restarted). This has no effect. Also, as far as I can tell, SMTP Relay accepts mail on public-ip:25, so do I need to change SMTP Relay?

This is really causing a major problem for us as we MUST be able to accept mail from any address. We use SA to work on spam, so that's not our issue (fortunately).

Any ideas?

The

FEATURE(`accept_unresolvable_domains')dnl

line needs to be in submit.mc

Then you run cd /etc/mail ; make submit.cf and restart sendmail.

That's it! My mistake was thinking this went into sendmail.mc.

Thanks!
