Have a Ubuntu 14.04.2 LTS, Exim 4.82-3ubuntu2, dovecot 1:2.2.9-1ubuntu2.1
running. Also have a quota option in append file transport with 300M value
for virtual users.
I received next log records:
...(-22): mailbox is full (MTA-imposed quota exceeded while writing to
tmp/1433399682.H314842P28479...
When I verified the size of maildir it was only 1K, but I start receive
messages about quota exceeded.
