man newsyslog

Newsyslog allows you to configure automatic rotation of log files.  It's
run automatically from cron every few minutes.  For my Exim logs, I have
the following in /etc/newsyslog.conf:

/var/log/exim/mainlog   mailnull:mail   640  7     *    $D0   Z
/var/log/exim/rejectlog mailnull:mail   640  7     *    $D0   Z

This means that the mainlog and rejectlog will be rotated every day at
midnight ($D0), the old logs will be compressed (Z), and 7 older versions
of each log will be kept.  Although I notice that it actually seems to be
keeping 8... Anyway, you can also set the permissions and ownership of the
logs as I've done here.  It's also possible to send a signal to a process
to tell it to re-open its logs, but this isn't necessary with Exim.
