Postfix user@domain ?

[cryptic]

I was able to get user@domain email login for dovecot working due to this post:

change the line in the /etc/dovecot.conf file

auth_username_format="%Ld_%Ln"

Is there a way to have outgoing email (postfix) work the same with it's authentication?

As far as I know, there is no easy solution for postfix. Maybe you can do this by authenticationg against the sasl user database instead of /etc/passwd, but you will have to write a script that adds all email users and passwords to the sasl database.

With Postfix 2.3 or later:

postfix/main.cf:
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth

dovecot/dovecot.conf:
auth default {
# Space separated list of wanted authentication mechanisms:
# plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi
mechanisms = plain login
passdb pam {
}
userdb passwd {
}
socket listen {
client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
}
}

(From http://www.postfix.org/SASL_README.html#server_dovecot)

That worked!

Here is my new dovecot.conf file for other interested parties:

-----------------------------------------------

protocols = imap imaps pop3 pop3s

protocol pop3 {
}

protocol lda {
# Address to use when sending rejection mails.
postmaster_address = postmaster@example.com
}

auth_username_format ="%Ld_%Ln"

auth default {
mechanisms = plain login

passdb pam {
}

userdb passwd {
}

socket listen {
client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
}
}

dict {
}

plugin {
}

That's a really cool solution I move the thread to the Tipps & Tricks forum.

This solution is simply GREAT!

But since i chaged config acording this post, i cannot log into roundcube webmail. Does anyone has idea what to change in RoundCube config?

log:
IMAP Error: Authentication for mydomain.cz_test failed (LOGIN): "a001 NO Authentication failed." in on line 0

Do you use a roundcube version that is patched to lookup the username, in your case "mydomain.cz_test" from the virtusertable? if yes, you must deactivate the lookup.

[radim_h]

eh, all what was needed is

change
// Path to a virtuser table file to resolve user names and e-mail addresses
$rcmail_config['virtuser_file'] = '/etc/postfix/virtusertable';

to
// Path to a virtuser table file to resolve user names and e-mail addresses
$rcmail_config['virtuser_file'] = '';

hello,

I try this parameters in dovecote.conf and when I restart service I have this error :
Restarting mail server: dovecotError: Error in configuration file /etc/dovecot/dovecot.conf line 11: Unknown setting: username_format

I make copy/paste this parameters directly on my dovecot.conf file.

Where is my error ?

Regards,
Olivier

What version of dovecot are you running?
