[TriLUG] Re: DNS Issues

[Jeffrey A. Groves]

Brian:

If sendmail can't find oifis2.bdmcc-us.com in DNS, then it aint gonna accept
the mail.

You can try adding this to /etc/mail/access:

oifis2.bdmcc-us.com             OK


and see if that allows the message through.  If it still does not, you may
have to add this to your sendmail.mc and regenerate your sendmail.cf:

FEATURE(`delay_checks')dnl



Thanks,

Jeff G.
