but unfortunately, I'm not enough of a programmer, so I have to ask here: Should I be able to delete mails from a maildir, and expect the quota plugin to notice the change?
I think it should notice most times, but not necessarily always. Can you reproduce this with simple steps? Meaning that if maildirsize file is either older than 15 minutes or longer than two lines, does Dovecot not recalculate the quota when user is over quota?
Yes, I can. However, the user is, strictly speaking, not over quota, since there are still a few bytes free. The new message would push it over quota, though. Does this make a difference?
These are the steps I took, starting from a "fresh" account (one whose home directory I deleted), and using swaks[0] to generate the mails. We use Postfix to pipe the messages to deliver, and have set quota_full_tempfail = yes.
Delete the user's home directory
Deliver 3 messages to the user, using
swaks -f ulrich@topfen.net -t grmpfl@example.net -s localhost
- maildirsize now shows:
cat Maildir/maildirsize
2000S 0 0 510 1 510 1 510 1
- Try to deliver a fourth message (also 510 bytes). As expected, it fails.
tail -n 2 /var/log/mail.log
