Hi
I'm still trying to get Postfix to use deliverquota to deliver the mails to my
Maildirs.
The only thing I could find on the net was a comment from Magnus
http://www.irbs.net/internet/postfix/0412/1673.html that I had to make my own
pipe.
So this is my attempt:
deliverquota unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/bin/deliverquota $domain/$recipient
One concern - vmail is not a user on my system (and since I copied this from
the maildrop pipe, I'm now wondering how mail is delivered at all.
Not via maildrop, since the user does not exist.
The first message postfix tries to deliver to the maildrop transport
will crash it with a fatal error.
For basic information on how (local) mail is delivered, read
http://www.postfix.org/OVERVIEW.html#delivering
My first question is, is $domain/$recipient the way to deliver a Maildir
structure that is always domain.tld/user where user is the portion before the @
- this is the way I've understood man pipe, but I'd like to be sure.
Do I need it to be unpriv or not?
The choice of mailstore is unrelated to any other postfix configuration
options; it's just a choice.
If you want mail to be stored in /var/mail/domain.tld/username then the
above will accomplish that.
I'm unsure what you mean by "unpriv" - postfix does not execute setuid
root programs, so in that sense, everything is unprivileged.
My second question is what happens when deliverquota refuses to deliver the
mail because the Maildir is over quota? Does postfix try to deliver a DNS?
That depends on the status deliverquota returns to postfix.
If it's a temporary error, the message will be deferred and retried later.
If it's a permanent error, the message will be rejected and postfix will
generate a DSN back to the originator.
