dovecot - Jun 2006 - postmaster alias

I have dovecot configured to use an LDAP database for mail delivery with
dovecot-lda. All of of my user accounts and aliases work fine except for
postmaster@ which consistantly bounces. I have compared the entry for
postmaster with another working alias and see no difference. When I send
mail to postmaster I get the following in the logs:

Jun 11 02:11:13 server1 postfix/pipe[12083]: 6D6CF33444:
to=<postmaster@mydomain.com>, orig_to=<postmaster>, relay=dovecot,
delay=3, status=bounced (user unknown)Jun 11 02:11:13 server1
deliver(treed@mydomain.com): saved mail to INBOX
Jun 11 02:11:13 server1 postfix/pipe[12193]: 6D6CF33444:

status=sent (mydomain.com)
Jun 11 02:11:13 server1 postfix/cleanup[12055]: 49F1F33431:

Jun 11 02:11:13 server1 postfix/pipe[12193]: 49F1F33431:
to=<treed@mydomain.com>, orig_to=<root@mydomain.com>, relay=dovecot,
delay=0, status=sent (mydomain.com)
Jun 11 02:11:13 server1 postfix/pipe[12083]: 49F1F33431:
to=<myboss@mydomain.com>, orig_to=<root@mydomain.com>,
relay=dovecot,
delay=0, status=sent (mydomain.com)

Then I get a bounce email back saying:

<postmaster@drjays.com> (expanded from <postmaster>): user unknown

The strange thing is that first I get the bounce and then the mail goes on to be
delivered to the two users (me and my boss) specified in the alias as it should
be. How is this possible that the user is unknown and then it goes on to deliver
to the alias?


I am running 1.0.beta8 pulled from CVS May 23 16:46 (PDT) with
openldap-2.2.13-4 on CentOS 4.3

Thanks for any clues you can provide!

The postmaster is just an alias, not a real account? In that case it
should never have even gotten to dovecot-lda. So that's a Postfix
configuration problem, but I'm not too good with Postfix myself so can't
help you there.
