After migrating Postfixadmin in our system with slight changes to current system. It was the basic of http://www.howtoforge.com/virtual_postfix_mysql_quota_courier. Trying to connect with telnet I get generic failure when using AUTH LOGIN and the log returns: I've also had errors like 'Permssion denied' and 'No such file or directory', but after removing the line 'saslauthd_path' these errors dissapeard and now gave me 'authentication failure'. I've been searching the whole internet last couple of days, checked group permissions and stuff, but nothing seems to work. Hopefully you can help me out.
