Thanks Witsie,

Could the use of an IMAP client program (workstation-based or web-based, like Squirrelmail) to access the incoming ("new/" Maildir) mailbox, somehow override the directive?

Or, what other, common tools could cause such an override?

Our users are virtual, and don't have shell or other access to the mail server, apart from POP/IMAP to their mailboxes (we are using Dovecot 1.2).

It's not an "override". Postfix is simply not involved, when, say, a user copies messages using a desktop IMAP MUA from a remote mailbox into the IMAP store. No postfix process runs whatsoever relating to all those IMAP transactions. Look into, for example, the dovecot quota module. Personally, I find it irritatingly complex and rely on the law of averages for my total mailbox store to be a reasonable size. Someday I'll work it out.
