I'm working on data-retention for my employer and I was wondering about
this. The wording is a bit vague in the manual page (we are now using
deleted to mean multiple things...). I have assumed that "-X 7" means
purge-the-message-seven-days-AFTER-IT-WAS-"EXPUNGED". Is this correct?
I believe the manual page could also be read to mean
"OLDER-THAN-SEVEN-DAYS" meaning it was received more than seven days
ago [equivalent to "ipurge -d 7 -X"].

I'd do it in python. :) I've done some similar things for walking the
entire mailstore and building statistics, etc... but it is REALLY slow!
A server side API for making tools like cyr_expire would be really nice.
