[Dovecot] Dovecot deliver discards emails (mail loss)
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello,
Dovecot deliver used with filesystem quota, sendmail v8.13 via
.forward-mechanism causes mail loess:
May 8 09:49:53 ux-2s11-9 deliver(dvtest):
msgid=<200705080749.l487nclf029596 at
ux-2s11-9.inf.fh-bonn-rhein-sieg.de>:

May 8 09:49:53 ux-2s11-9 deliver(dvtest):
msgid=<200705080749.l487nclf029596 at
ux-2s11-9.inf.fh-bonn-rhein-sieg.de>:
Return-Path missing, rejection reason: Not enough disk space

/etc/mail/runde", ctladdr=dvtest (31045/102), delay=00:00:15,

"/etc/mail/runde" is a shell script to capture various status of the
delivery attempt, incl. a strace log.
Below are the last lines of the strace.
Actually, I expected deliver to _tempfail_ the delivery attempt with "out
of quota". However, the mail is lost, I guess, because sendmail received a
return code "0".

Can you show the entire log history for message id l487nclf029596? Of course, if there was no return-path, then no bounce would be generated.
