I've setup dovecot to use user/password files to store username and passwords and I'm able to login via roundcube successfully, which makes use of those files via dovecot. I have setup Postfix to use virtual_transport = dovecot so since dovecot is now able to see my maildirs, usernames and their associated passwords, I would expect Postfix to have all that it needs to authenticate users sending mail and to deliver incoming mail to their maildirs. That doesn't seem to be the case though and I wonder if someone can give me some pointers? I didn't use the following directives in the /etc/postfix/main.cf virtual_mailbox_domains virtual_mailbox_base virtual_mailbox_maps virtual_uid_maps virtual_gid_maps because dovecot already knows all those things and since we're using "virtual_transport = dovecot" I guess they are not needed? Here is my postconf -n output Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 default_destination_concurrency_limit = 5 home_mailbox = Maildir/ html_directory = no in_flow_delay = 1s inet_protocols = all local_recipient_maps = mail_owner = postfix mail_spool_directory = /var/mail mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain myhostname = mail.bk1.server mynetworks_style = host myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot unknown_local_recipient_reject_code = 550 virtual_transport = dovecot here is my dovecot -n Code: # OS: Linux 2.6.32-279.2.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) ext4 auth_mechanisms = plain login disable_plaintext_auth = no last_valid_gid = 1000 mail_gid = 502 mail_location = maildir:/var/mail/%d/%n/Maildir mail_uid = 501 passdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } ssl = no userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } verbose_proctitle = yes The server will be host to a few virtual domains. Thanks, I really appreciate your attention. Peter
You need to tell postfix that dovecot is going to be your LDA (local delivery agent), so you need to edit the postfix/master.cf file and put something like this in it: Code: dovecot unix - n n - - pipe flags=DRhu user=vmail:mail argv=/usr/libexec/dovecot/dovecot-lda -f {sender} -d ${recipient} You will also need to disable SELinux or find some way to make it work with dovecot as the LDA, i tried for ages and couldnt, so gave up.
