Question : Maillog Connection refused Over and Over and Over

Hi All,

I have a new install of Linux 9 as a mail server using sendmail 8.12.8.
My maillog file is gigantic for only 10 users (120mb.) a week and growing. Can someone explain what is going on?

The maillog seems to repeating the same line over and over, basically: stat=Deferred: Connection refused by [127.0.0.1]

I've clip a portion of the maillog and attached it.

Thanks in advance!

Answer : Maillog Connection refused Over and Over and Over

Ahh, well that makes sense. What you'd done by specifiying an IP is to limit Sendmail to only listening on a single IP. Sendmail 8.12.x requires that it listen on at least 127.0.0.1 and the IP of the machine.
