Hi;
        I use checkvpw from vmailmgr package for pop3 authorization.
        But it treat all login name correctuser@incorrectdomain as system-account
user.
        
        How to configure the vmailmgr to give an error for such a situation?
        
        Thanks inadvance.

Regards;
Michael
