[Dovecot] Postfix - deliver problem.

I  really could use some help.

I have been using dovecot and qmail on Debian for years with no problems.

I just replaced qmail with Postfix and have not been able to get  messages
to dovecot via deliver.

I have tried to set it up as a virtual mailbox only "no lookup necessary"
system following the vaious help pages. I am using just a single user
vmail:mail to execute postfix and deliver.

My Dovecot.conf is:

# 1.2.16: /etc/dovecot/dovecot.conf

I have the dovecot deliver line in postfix's master.cf according to the
dovecot unix    -       n       n       -       -      pipe
  flags=DRhu user=vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d

Incoming emails are being saved to the Postfix queue but then delivery is
unsuccessful with an error message of:

2010-12-26 23:11:09 deliver(mark at bronsteinlaw.com): Error: userdb lookup:
connect(var/run/dovecot/auth-master) failed: No such file or directory

Any help would be appreciated.
