Hello, I have a new director ring I am setting up on centos 7 with dovecot 2.3.1. I haven't been able to replecate this in testing, but as soon as I start pushing production traffic to the new ring I see dozens of these in the logs: Apr 18 00:34:00 d.director.imapd.sonic.net kernel: imap-login[163107]: segfault at 10 ip 00007ff625698dd5sp 00007ffe4b77bb28 error 4 in

Hello, given a small organization. There are *personal* mailboxes (mailbox per user, incl. subfolders et cetera).

They are not associated with a specific account,

This appears to be breaking dsync at the moment and is caused by something committed in the last week or so. This is with the current -git of dovecot-2.2 (eaf276b33).
