Put something like this in /etc/logrotate.conf 

# Newslog
/var/log/newslog  {
    missingok
    compress
    size 2M
    rotate 3
    create 0660 root news
}

or the individual files such as

[root www root]# cat /etc/logrotate.d/amavis.log
# Restart amavisd when rotating amavis.log
/var/amavis/amavis.log {
    rotate 4
    compress
    size 4M
    postrotate
        /sbin/service amavisd restart 2> /dev/null || true
    endscript
}

I rotate both on time and size. This forces a rotation monthly:

[root www root]# cat /etc/cron.monthly/logrotate
#!/bin/sh
 
/usr/sbin/logrotate -f /etc/logrotate.conf

This checks it daily for size:

[root www root]# cat /etc/cron.daily/logrotate
#!/bin/sh
 
/usr/sbin/logrotate /etc/logrotate.conf

The size overrides the date unless the -f option is used. Hence, I always
rotate at the first of the month or whenever the size reaches the set size.

HTHs.
