However, plaintext authenication was most definitely not disabled. Using www.untaken.net/mail/ which is hosted on the same box as dovecot I could get this plaintext failure constantly using cara.untaken.net, but switching to 'localhost' instead would work fine, despite being the same physical machine.
I'm baffled at what could cause this, I put my currently conf over at www.untaken.net/dovecot/ just for reference, I've modified various bits now from the default in a desperate attempt to get it working. Has anyone else seen anything like it?
Hello.
I just took a look at your configuration file, and it appears as though plaintext authentication is disabled. The default setting for disable_plaintext_auth is yes (search for in dovecot.conf - it's there). Try adding disable_plaintext_auth = no and see if this fixes your problem. I believe that plaintext connections to localhost are always allowed despite this setting.
