Currently if user is 1MB under quota and someone tries to deliver mail that is over 1MB, Dovecot rejects the mail. But smaller mails aren't rejected probably for days. So user might not even realize that they didn't receive one of the mails. Also having a user "almost over quota" is a rather strange state I think.
So what do you think about v2.2 allowing delivery of one last mail even if it brings the user over quota? Except add a limit that if the message size is as much as the user's entire quota limit it wouldn't be added (or 50% or ..?). Also IMAP wouldn't allow this, since user would get an error anyway. I could make this also optional, but if nobody really wants to keep the old behavior there's really no point in adding the option.
How about this, added to hg:
plugin { # LDA/LMTP allows saving the last mail to bring user from under quota to # over quota, if the quota doesn't grow too high. Default is to allow as # long as quota will stay under 10% above the limit. Also allowed e.g. 10M. #quota_last_extra = 10%% }
Each quota root has its own limit, so if using multiple quota roots (pretty rare) you'd have to set also quota2_last_extra, etc.
I wonder if there's a better name for this than "last_extra"..
