Being the filty perl programmer that I am, I would just make an admin
IMAP connection to the server, LIST all mailboxes, regex match the ones
I wanted, select them and process them.

We do this by setting our own special flag (in addition to the regular
\Deleted flag) and then SEARCH for those messages only and UIDEXPUNGE
them.

But if you're deleting ALL messages, then it doesn't really matter does
it?  Unless you're doing some sort of age based thing, in which case
like I said - UIDEXPUNGE.  The flag just lets us persist the action
across dropped connections.
