Hello Simone, I've been trying for the past days to replicate the problem...
Since we're on a production environment, I can't put dovecot in debug mode and leave it in debug for an entire day, so I've been checking the queue every half an hour and as soon as a mail got stuck, I'd change mail_debug to yes and reload dovecot's config. Well, everytime I've done this, the mail got delivered except once. Just one time. On the back end I got this log: Jun 23 12:17:00 dovecot: lmtp(10680): Connect from a.b.c.d Jun 23 12:17:00 dovecot: lmtp(10680): Debug: auth input: u...@domain.it quota_rule=*:backend=104857600S home=/mnt/mbox1/mailusers/u...@domain.it/ Jun 23 12:17:00 dovecot: lmtp(10680): Debug: Added userdb setting: plugin/quota_rule=*:backend=104857600S Jun 23 12:18:00 dovecot: lmtp(10680): Disconnect from a.b.c.d: Connection closed I compared the log of the stuck mail with a mail that gets delivered, and I noticed that there are a few more lines of debug... in fact, after the "Debug: Added userdb setting" I see: Debug: Effective uid Debug: Quota root Debug: Quota rule Debug: maildir++ saved mail to INBOX Connection closed I hope this info can help.
