[Mimedefang] Connection refused by ... /mimedefang.sock on Debian Squeeze

[jm130794]

Hello,

We have a problem with MIMEDefang on Debian Squeeze distribution. The
versions of software are :

- Sendmail 8.14.3
- MimeDefang 2.71

All works fine during few hours and suddenly, we get this error in logs :

Milter (mimedefang): error connecting to filter: Connection refused by
/var/spool/MIMEDefang/mimedefang.sock

Is there a bug in Sendmail or the Milter library ?

The content of our filter is very simple. We only check if the
connected user is in a list of valid users. No Spamassassin or other
filter.

We must restart the MIMEDefang daemon for send or receive emails.

Is a problem linked to Debian distribution ?

For now, is there a solution to restart automatiquement the MIMEDefang
daemon when we receive this error ?

Thank,

Jean-Michel
