Hi,

I was wondering if I could get some help here. Recently, I decided I want to move from Windows XP Pro OS to a Linux OS such as Ubuntu. I am new to Linux OS but willing to learn. I have installed Ubuntu Server 10.04, Apache2, MySQL5, PHPMyAdmin, Postfix, DoveCot and Squirrelmail on my server. I have checked them all and they are all up and running at the moment. Now, what I am trying to do here is to add a couple of users and see whether they can login to squirrelmail. The result is none of those two users are able to login. I went to check the mail.log and the error message is as follows Ubuntu-MailServer dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured

My silly question is I do not quite understand what the above error means. How do i enable users to login and test to see if they can send and receive emails. Users can login via squirrelmail.

Any help would be greatly appreciated.
