HI folks,
I've an up-to-date CentOS 5.x box on a small intranet (<20 users).
We did a reboot over the weekend and all appears well except that
clients on the LAN can no longer send email. Just hangs/times out.
No clear identifiers in the /var/log/maillog or /var/log/messages.
inserted update:
It does appear there's something in /var/log/maillog. I found this
entry, repeated a few times for users (now that they're here and using
the system).
Jun 9 09:10:49 gungho sendmail[13074]: m59D9b47013074: lost input
channel from [172.16.0.155] to smtp after mail
We're not setup for ESMTP as it's a closed network and I'm really
hoping for a kickstart as to where to look to get this going.
In case it helps, my sendmail.cf file is below.
Thanks in advance.
