Topic: SMTP Authentication failed
==== Required information ====
- iRedMail version: 0.8.5
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP
- Linux/BSD distribution name and version: Ubuntu 12.04
- Related log if you're reporting an issue: roundcube: SMTP Error: SMTP error: Authentication failure: SMTP server does not support authentication (Code: ) in /usr/share/apache2/roundcubemail-0.9.2/program/include/rcmail.php on line 1014 (POST /mail/?_unlock=loading1382550291714&_lang=undefined?_task=mail&_action=send)
I have set up postfix to use port 587 because I don't want to use 25.
I have changed "$rcmail_config['smtp_port'] = 587;" in main.inc.php and in /etc/postfix/master.cf enabled "submission" and disables smtp.
When I try to send from roundcube I get "SMTP Error (250): Authentication failed."
