[fetchmail]delete messages after x days?

fetchmail-friends,

hi, i just looked through all of the archives for fetchmail-friends
and noticed that some people had the same question i have: can
fetchmail be set to delete messages older than x days? The idea is
that when the mail is checked, it doesn't delete what it just
downloaded, but rather it deletes the messages that are of a certain
age.

perhaps you replied to them, but the answer didn't appear on
fetchmail-friends, afaik.

So, _can_ fetchmail do that?

Thanks,
-andrew
