HowtoForge Forums | HowtoForge - Linux Howtos and Tutorials - Configuring Postfix (virtual

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

local_recipient_maps =

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain                                                            

myhostname = mail.bk1.server

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. :-)
