please help: trouble logging into pop3 with postfix & dovecot
I am doing a project for a linux class in college. My goal is to build a linux email server, and I am using postfix and dovecot. Everything seems to be going well, but I have run across a problem. I am trying to log into my pop3 on dovecot with outlook express. I have my user and pw typed in correctly, and it keeps asking me for my user and password.
This is the error outlook express gives me:
There was a problem logging onto your mail server. Your User Name was rejected. Account: 'postfix.cita430.com', Server: 'postfix.cita430.com', Protocol: POP3, Server Response: '-ERR Plaintext authentication disabled.', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC91
I picked out the "-ERR Plaintext authentication disabled." error because I figured it had something to do with that. I went into my /etc/dovecot/dovecot.conf file and found where it said "#disable_plaintext_auth = yes", I uncommented it and changed the yes to no so it read "disable_plaintext_auth = no", and tried again to log into pop3 with outlook express.
Now there is a new error and it says:
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'postfix.cita430.com', Server: 'postfix.cita430.com', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC0F
I have since changed it back the way it was since I seemed to be getting better results with it, well atleast A RESULT (where it would ask me for my user name and password repeatedly). I am pretty lost. I have been researching this for hours on the web and haven't had much luck, so I figured I'd make an account on this forum and ask here.
I would appreciate any and all help that anyone would be willing to throw my way. I don't think this is something too terribly complex, I am just new to this and haven't quite got it figured out yet.
