One of my users with a pretty full mailbox reported getting messages about his mailbox being 95% full every few minutes. As fast as he was deleting messages, iRedMail was sending him new messages about the mailbox being nearly full. This was viewed as counterproductive, as it took up mailbox space.

Curious if these messages are supposed to be throttled to only show up at the time threshold is passed, then hold off a while? Wondering if he was cleaning up just enough, then a new message arrived (plus then the notice from the mail server). Might be good to hold off sending additional mailbox-size messages for, say, an hour after the last one was sent in case a user is in the middle of trying to clean up.
