Plesk 12.5.30 on CentOS 7.2 64-Bit
Outgoing mail control is logging almost exactly 2800 mail send attempts per hour, but the subscription is not sending mail or much less. The number "2800" started out as "100", a few days later 300, then 500, 800 and so on. It seems that the statistics of outgoing mail control are miscalculated for that subscription as the number increases by a few hundred every other day (or so), then remains at the same level for a few days, then rises again.

Outgoing mail control incorrect count of send attempts
