Hello All, I've installed ISPConfig 2.2.5 no problem, but after struggling with the DNS not working, i decided to use an external DNS server. Now that I have that working, I am unable to login to the mail server from a client, e.g. Outlook Express, using either POP3 or IMAP, says "Password Rejected". I removed the username prefix as I am only using one domain, I tried testing using [email protected], with username postmaster and I can't login to the server. This is what the logs look like: mail.log- Sep 16 09:24:43 ispconfig courierpop3login: Connection, ip=[::ffff:192.168.123.1] Sep 16 09:24:48 ispconfig courierpop3login: LOGIN FAILED, ip=[::ffff:192.168.123.1] Anyone have any ideas on how to solve this problem? Any help is appreciated.
