[Mimedefang] HUGE problem with mimedefang

[Lisa Casey]

Hi,

I've been using Mimedefang together with Spamassassin for some time now with 
no real problems. But last night, shortly after midnight mimedefang had a 
big problem which prevented e-mail from working until I got into the office 
shortly before 9 AM, discovered the problem and fixed it. I fixed it by 
stopping the Sendmail daemon in /etc/init.d (I got the error that there was 
no PID for Mimedefang) then restarting Sendmail (Sendmail and Mimedefang 
started successfully and e-mail began working properly). Since I work at an 
ISP, I've had customers complaining all morning.

In my maillog I see errors such as these:

Apr 21 00:52:15 Raydeus-Dee sendmail[23854]: j3L4jOGx023854: Milter

When I got Mimedefang going again, I see this in the log (don't know if this 
is normal or abnormal):

Does anyone have ANY idea what might have caused this to happen?

Thanks,
