I've got a task of migrating one mail server from one box to another and so far I have configured Postfix and it's working. But, Courier pop3d server fails without exception.
So, I have Courier pop3d server which needs to authenticate user agains MySQL database.

Oct 20 03:40:22 vps-1161420-22112 pop3d: authentication error: Input/output error
The last two lines of don't say much on what could the IO error actually be.
I have configured mysql connection within file: /etc/authlib/authmysqlrc:
MYSQL_SERVER localhost
MYSQL_USERNAME postfix
MYSQL_PASSWORD some-password
....
other mysql settings
I have verified that I can connect to MySQL itself using there credentials.
So, is there some way to increace verbosity of pop3d or authmysql? I have set DEBUG_LOGIN=2 in authdaemonrc file.
Thank a lot!
