Why would the script be looking at the contents of the messages at all? <uch css having to "deal" with the subject? If you are using maildir, you have the timestamp in the filename, and you can easily sort a message into yyyy.mm folders from there. You can also, considering the size of the mail isn't in the multi terabyte range, just use filtering to do this for you (filtering of tour choice, I'd guess most any filtering could handle it).

But the question is, why do you have to archive this 180GB of mail?

Do you simple have to preserve it? In that case, tax cjf works great! After all, sorting mail that no one is ever going to look at is unlikely to be worth the effort, is it?

If you need to have constant access to it, then you should probably get those emails into a fast DB of some sort.
