Re: [Dovecot] Posfix and Dovecot (dovecot like LDA) and no space left on the disk
Here is the logs:
May 8 06:00:36 mailserver dovecot: deliver(sazima@vendys.net): msgid=<3DEF56667E754F24B163C9767422C9A9@dlllk.local>: save failed to INBOX: Not enough disk space May 8 06:00:36 mailserver dovecot: deliver(sazima@vendys.net): msgid=<3DEF56667E754F24B163C9767422C9A9@dlllk.local>: rejected: Not enough disk space May 8 06:00:36 mailserver postfix/pickup[27640]: D8B242F9E1: uid=150 from=<> May 8 06:00:36 mailserver postfix/pipe[27978]: 4B3A72F8C0: to=<sazima@vendys.net>, relay=dovecot, delay=11, delays=11/0.02/0/0.04, dsn=2.0.0, status=sent (delivered via dovecot service) May 8 06:00:36 mailserver postfix/qmgr[18807]: 4B3A72F8C0: removed
Problem is, that:
- spool HAVE ENOUGH space (so postfix has no problem keeps the message in the spool)
- postfix forward message to dovecot
- dovecot accept message, but can not deliver to /home/vmail, because there is no space :-)
- so dovecot lost/delete/refuse message and tells postfix - everything is Ok ?
- postfix cleans qmgr (bacause message has been forward to LDA succesfully I suppose :-) )
Thanks Peter

Oh, it's a rejection.. I guess it's because it's handled the same way as "out of quota". Two things you can do:
a) give -e parameter to deliver, so it exits with the proper code instead of sending a new "rejected" message via sendmail. (I think I should have made this the default in v2.0.. Maybe I could change it in v2.1.)
b) quota_full_tempfail = yes to have it exit with tempfail rather than a permanent failure

Do you intent any time soon to provide some hook to alow MTA reject in reply to "RCPT TO:" (in SMTP session) messages to over quota mailboxes?
Exit code of "deliver -e" can only be used to reject message in reply to "the final dot" *for single recipient messages*.

Can you give specifics of what I'd need to do for that? I remember there is some sendmail protocol that is also supported by Postfix (I think), but I can't remember specifics (and a bit lazy to google for it). v2.0 would finally allow easily implementing such service. Hmm. I guess such service would both have to check if the user exists and also the quota value, and give errors about both of them.

Both sendmail and postfix support milter protocol/API. Unlike API provided by library the protocol is "not officially" documented. Sendmail/sendmail.cf could also use trivial "socket map" protocol (query->response) [sample Perl scripts implementing it are in contrib directory of sendmail distribution].
IMHO the best honeypot for developers (especially without dovecot expertise) would be simple library providing two functions email_address -> state( does_not_exist, under_quota, over_quota) email_address, message_size -> ( does_not_exist, ....).
