just use json log format and rsyslog.

In amavis config:

$logline_maxlen = ( 32*1024 ) - 50; # 32k max message size, keep 50 bytes for syslog
$log_templ = <<'EOD';

You may want to increase the maximum message size in rsyslog:

$MaxMessageSize 32k

The default is afair 2k.

Then use a reliable logging to forward your log to a central log server:


On the central log server you can easily extract the data from your
logs with a log processor like logstash:


If you want to build some kind of log statistic web site then elasticsearch
and kibana may be of intresst for you. Google for "ELK stack"
