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>: 
save failed to INBOX
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
May  8 09:49:53 ux-2s11-9 sendmail[29618]: l487nclf029596: to="| 
/etc/mail/runde", ctladdr=dvtest (31045/102), delay=00:00:15, 
xdelay=00:00:00, mailer=prog, pri=120033, dsn=2.0.0, stat=Sent

"/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".
