Thanks Leon I changed my SQL to the following after trying a few combinations:
user_query = SELECT maildir, 5000 as uid, 5000 as gid,concat('maildir:bytes=',quota) as quota FROM virtual_mailbox WHERE username = '%u' It seems that Dovecot didn't understand the * backend for some reason (even though it's mentioned in the documentation) and my logs now seem to picking up on this May 09 22:29:09 IMAP(t...@example.com): Info: Effective uid=mailuser, gid=mailgroup, home=(none) May 09 22:29:09 IMAP(t...@example.com): Info: Quota root: name=bytes=1 backend=maildir args= But the address in question is still receiving mail - should I be doing something additional to cease mail delivery? Thanks in advance!
