Check if the Username and Password you specified in >smtpd.conf is correct. MySQL is running and username and password are correct, because I can login to PHPmyAdmin using them. Verbose is on in MySQL, but there are no entries corresponding to SASL login attempts in the log. The port thing may be interesting. How can I determine on which port mysql listens. nmap [IP] does not show any entry with "mysql". Does that mean MySQL is not listening on 3306? How dies PHPmyAdmin connect to mysql? I may be wrong, but I think Debian installs postfix chrooted. Maybe that is the point (postfix blocked by chroot)? By the way, when talking about Inet-Ports: Is that something different to the usual Ports when talking about Internet applications? -- Herbert
