Hi guys,

Mail is not delivering on my server. I keep seeing the following in mail.log - any suggestions?

This only started happening this morning for no reason!

Re: Issues with mail delivery (ClamAV)

To temporarily get mail flow back working, I've commented out content_filter = smtp-amavis:[127.0.0.1]:10024 in /etc/postfix/main.cf

It's slow now, but it's working at least!

Re: Issues with mail delivery (ClamAV)

I am also having this issue, seems to be related to fail2ban also.

When either fail2ban or clamav are running the CPU usage hits 100% and  brings mail delivery to a stop.

Stopping both services does allow mail to be delivered.

Re: Issues with mail delivery (ClamAV)

Re: Issues with mail delivery (ClamAV)

Try to run clamd service manually like this:

clamd -c /etc/clamav/clamd.conf --debug

I expect it will print some unsupported parameter names. If it does, comment out or remove these parameters from clamd.conf.

Re: Issues with mail delivery (ClamAV)

Hey,

This is what it returned:

$ clamd -c /etc/clamav/clamd.conf --debug
ERROR: Parse error at line 79: Unknown option StatsEnabled
ERROR: Can't open/parse the config file /etc/clamav/clamd.conf

The last one is concerning?

Cheers,
Dara

This is the point, remove 'StatsEnabled' parameter from clamd.conf and restart clamav.

Re: Issues with mail delivery (ClamAV)

Same issue here. Ended up removing several lines in order to be able to run the service manually ...

...
MaxIconsPE 100
PCREMatchLimit 10000
PCRERecMatchLimit 5000
PCREMaxFileSize 25M
ScanXMLDOCS true
ScanHWP3 true
MaxRecHWP3 16
#StatsEnabled false
#StatsPEDisabled true
#StatsHostID auto
#StatsTimeout 10
StreamMaxLength 25M
#LogFile /var/log/clamav/clamav.log
LogTime true
LogFileUnlock false
LogFileMaxSize 0

Things seem to be working now smile
