[Exim] A script to delete old message?

Hi all,

Basically what I want to do is to set up a cron job that will delete old (>
2 weeks) tagged spam suspect from
the spam folder(mailbox) of each individual account.

Does anybody here have an example that I can use as a reference? If not, any
suggestion will be appreciated.

I am using exim 4.24 on RH8.0

Thank you.
