Note : The Fix is applicable only for Webuzo installed on CentOS 6.x as it install Exim 7.2 which handles the fix.

The following changes are required so as to get away with the “550 relay not permitted“:

1) Dovecot Configuration
/etc/dovecot/conf.d/10-auth.conf says:

auth_mechanisms = plain

Change it to:

auth_mechanisms = plain login

2) Exim Configuration

Add to /etc/exim/exim.conf in “AUTHENTICATION CONFIGURATION”:


dovecot_login:
driver = dovecot
public_name = LOGIN
server_socket = /var/run/dovecot/auth-userdb
server_set_id = $auth1

dovecot_plain:
driver = dovecot
public_name = PLAIN
server_socket = /var/run/dovecot/auth-userdb
server_set_id = $auth1


auth_advertise_hosts = *

Restart the Exim and Dovecot Service

ROOT > service exim restart
ROOT > service dovecot restart

Done !!!

Hope that was a Quick Trick.
