[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 # OS: Linux 2.6.18-194.17.1.el5.028stab070.7 i686 Debian 5.0.7 simfs log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot_info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 112 last_valid_uid: 112 first_valid_gid: 8 last_valid_gid: 8 mail_location: maildir:/var/mail/domains/%d/%n/Maildir mail_debug: yes mail_full_filesystem_access: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: postmaster_address: mark@bronsteinlaw.com mail_plugins: sieve log_path: /var/log/dovecot/dovecot-local-deliver.log auth_socket_path: var/run/dovecot/auth-master auth default: user: vmail verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=vmail gid=mail home=/var/mail/domains/%d/%n allow_all_users=yes socket: type: connect master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: mail plugin: sieve_global_dir: /etc/dovecot/sieve/global/

I have the dovecot deliver line in postfix's master.cf according to the docs:

dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient}

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@bronsteinlaw.com): Error: userdb lookup: connect(var/run/dovecot/auth-master) failed: No such file or directory

Any help would be appreciated.

Thanks,
