Sendmail is unable to resolve the domain. This also happens when trying to send to a problem domain. The mail simply sits in the queue unable to resolve.
[root@smtp01 root]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 smtp01.gvl-priv.sys.nuvox.net ESMTP Sendmail 8.12.8/8.12.8; Thu, 2 Oct 2003 13:55:03 -0400
helo localhost
250 smtp01.gvl-priv.sys.nuvox.net Hello localhost [127.0.0.1], pleased to meet you
mail from: test@xxxxxxxxx
451 4.1.8 Domain of sender address test@xxxxxxxxx does not resolve
I am running the following versions:
bind-9.2.1-16 sendmail-8.12.8-9.90
Any ideas? This is causing problems for our customers and I am beating my head against the wall trying to figure out what is wrong. I recently switched to rh9 from rh7.3 and this issue didn't happen on the old servers.
Thanks, Wiley
