Archiving mail automatically

Hi there,

I’m really new in the Mac OSX world and I have a little question…
We have a Mac OSX server (10.5.5, going to run 10.5.6 very soon) running postfix and cyrus to deliver mails.
My boss is asking me to find a way to manage archive automatically.

I thought about using procmail to copy anything received by postfix into archives-mailboxes.
After this “archive copy”, procmail should send the mail to cyrus which is going to deliver the mail.

So I’d have : postfix > procmail > cyrus

I also thought about using Sieve but it doesn’t seem as complete as procmail.

I’ll then run archivemail (http://archivemail.sourceforge.net/) on a daily basis to purge the old mail from the users mailboxes.

Allright, now, the questions 🙂

– What do you think about that solution ? Have you ever done something similar ? Do you have another solution ?
– Is there something I should know before starting this ? I’ve read some doc but they are all a bit old (2003-2005) so I don’t know if things have changed since those dates…?
– If you have any useful link, that would be really great.

Thanks in advance for any comment/thought/remark/idea/whatever 🙂
