Moreover, the sendmail log wouldn't claim that the mail had been delivered successfully in this case. You can return any message by printing to stdout or stderr. b) "rejection reason: Not enough disk space" is not a permanent, but a temporary failure. error = mail_storage_get_last_error(storage, &syntax, &temporary_error); in src/deliver/deliver.c near line 700 should set temporary_error. c) If Deliver cannot send the bounce - for whatever reason -, it had not saved the message either, hence, it must not simply ignore the fact, but at least should tempfail the mail. So I do interprete the "return smtp_client_close(smtp_client);" near line 121 of src/deliver/mail-sent.c as well for the case that the rejection is attempted. You have been right, sendmail does not put Return-Path into the mail, but a From only, when using the .forward mechanism. When using Deliver as mailer, there is the Return-Path.

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=<[EMAIL PROTECTED]>:
save failed to INBOX
May 8 09:49:53 ux-2s11-9 deliver(dvtest):
msgid=<[EMAIL PROTECTED]>:
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".
