Hi,

I upgraded from Dovecot v2.0.16 to v2.1.7 over night and I noticed this morning that one of my daily reports which lists summarised mailbox sizes per user has started listing nonsense for vsizes.

The reporting script at its core calls :

doveadm -f flow mailbox status -A -t 'messages vsize' '*'

It appears that Dovecot 2.1.7 is not resetting the vsize after collating the sum total of mailboxes sizes for each user, so that vsize just constantly increases as it iterates over each user.

Eg:

# doveadm -f flow mailbox status -A -t 'messages vsize' '*'

accounts@example.com messages=1 vsize=759 adam@example.com messages=0 vsize=759 amy@example.com messages=24 vsize=51699697 andy@example.com messages=5446 vsize=3220940815 anna@example.com messages=50 vsize=3224035563 careers@example.com messages=1 vsize=3224036311 craig@example.com messages=2471 vsize=4421343199 creative@example.com messages=189 vsize=4426884182 david@example.com messages=8 vsize=4440729729 davidw@example.com messages=0 vsize=4440729729 enquiries@example.com messages=1 vsize=4440730491 gemma@example.com messages=4109 vsize=6349098844 gin@example.com messages=86 vsize=6392599904 holly@example.com messages=2000 vsize=7200342663 ian@example.com messages=0 vsize=7200342663 info@example.com messages=4 vsize=7200558689 jackie@example.com messages=2 vsize=7200721146 jade@example.com messages=137 vsize=7210548548 jake@example.com messages=16667 vsize=15260532446 katie@example.com messages=1 vsize=15260533375 mark@example.com messages=0 vsize=15260533375 mike.a@example.com messages=9 vsize=15261474205 mike.s@example.com messages=296 vsize=15314352543 mike@example.com messages=6357 vsize=20631446344 nick@example.com messages=1184 vsize=21038046728 social@example.com messages=65 vsize=21038935461 will@example.com messages=85 vsize=21057572390 [SNIP]

The same occurs with -u '*@example.com' in place of -A, and also for 'all' in place of 'messages vsize'.

Is this expected behaviour in 2.1.x compared to 2.0.x, or have I stumbled upon a bug?
