logrotate problem (maybe)

Hi
Do any of you guys have a logrotate config file other than the default?
I have a Hardy server, with postfix/dovecot on it, and I just noticed
that despite me having set 'monthly' in /etc/logrotate.conf (as the
global default), the /var/log/mail.* logfiles are still rotated daily.
One of my very first steps when installing a Linux server (centos,
fedora, and now ubuntu) is to tweak the logrotate config so it rotates
the logs monthly (when on low traffic server), compresses them and keeps
1-3 years of logs. This is MY default tweak and never had a problem
with it so far (AFAIK ayways).
I was pretty upset when i wanted to install mailgraph to create some
graph of older logs (I installed this server a couple of months ago) to
see some mail stats, and found out that I have only a week worth of
logfiles.
I looked at it for a while, didn't find anything wrong with the config,
there is no other config in /etc/logrotate.d/ which would mess with
/var/log/mail.* files, I didn't find any other crontab entry with other
logrotate scripts, the default logrotate uses /etc/logrotate.conf, the
machine is pretty much up 24/7, ntp is running, clock is always syncronized.
Logrotate does work, because logs get rotated, for example the apache
logs are just fine, they get rotated once a month (but then again, there
is a separate /etc/logrotate.d/apache2 config for them, which I also
tweaked for monthly rotation).
/var/log/syslog files are also rotated daily and not monthly.
Here is my logrotate.conf file
http://pastebin.ubuntu.com/167652/
Maybe it's just some hidden default setting I don't know about, but it
bothers me that my maillogs are gone and I can't even set it up right.
It looks to me as if the global default isn't being used, or it's
overwritten somewhere.
Thanks.
