Thanks for your fast reply!
Probably my mail was not clear: I agree, there is now error due to
Postfix. It probably behaves as it is configured and as it should (but:
not as I would like it to behave in this situation ;-))
Let's assume, I have a $HOME/.forward which forwards mails for "abf" to
the external Mail-adress "axel-freyn@gmx.de", and keeps a local copy in
/var/mail/abf.
Then I would like to have the behaviour:
a) If the mailbox_size_limit for /var/mail/abf is NOT reached:
- a copy of the mail is stored locally in /var/mail/abf
(that is done by Procmail, I think?)
- a copy of the mail is forwarded to axel-freyn@gmx.de (with a new ID
(here: B4E2015C0FA).
(that is done by postfix/local?)
b) If the mailbox_size_limit for /var/mail/abf IS reached:
- local delivery to /var/mail/abf fails, (maybe creating a
SOFTBOUNCE)
- nevertheless, a copy of the mail is forwarded to axel-freyn@gmx.de.
However, I did not succeed to obtain the second case. As my Postfix is
configured now, it first tries to do the local delivery using procmail,
and it stops the complete delivery process if procmail fails. So, if the
mailbox_size_limit IS reached, postfix does NOT forward the mail to
axel-freyn@gmx.de.
So maybe my question could be reformulated as:
Can I tell Postfix: "FIRST do all forwarding ($HOME/.forward and
/etc/aliases), and THEN pass the mail to procmail"?
That would result in my desired effect:
- Mails are ALWAYS forwarded -- even when the local mailbox is full
- Mails are locally delivered if the local mailbox_limit is not reached
If the local mailbox is full, this "local copy" of the mail is
returned with a Softbounce.
