SPAM: where do I control the logging from ZMD ?

The logging from zmd is a little atypical - any chance of bringing it under control of logrotate etc.? I don't really want all these tiny files piling up in /var/log/. /etc/zmd/zmd.conf does not seem to offer many options. /Per Jessen, Zürich -- http://www.spamchek.com/ - managed email security.
