[Mailman-Users] Mailman not posting after antivirus installation

[Krishna Rao SN]

Hi Lists,

I was using mailman on my server (RH Linux) without any problems.

Recently installed Sophos antivirus software on the mail server along with mailmonitor (virus scanner) to combat virus/worms from the incoming mails.

Now after installing virus scanner, mailman is not functioning i.e., mail is not sending/ditributing to list members?

It is also not queued up in /var/spool/mqueue

Any suggestions
