ERROR: Connection dropped by IMAP server
It really WAS mailadmin (not mail_admin). However, I have now installed everything afresh. When trying to log-in, I now get the "Unknown user or password incorrect." message (I enter "info@localhost", which is defined this way in the users table of the mail database of Mysql).
In addition, there are various errors in "mail.info" and "mail.log" respectively.
"mail.err" is empty. I suppose there are errors in my definitions. In any case I enclose the pertinent snippets of the two files. I would very much appreciate your help - I consider myself a newbie in this complex matter. Thanks in advance - and greetings from Salzburg
