I got vpopmail and mysql to work togeather, it rights to the database and 
all. But its not accepting my password, i try my login with the @domain.com 
at the end, and nothing works, i know I have it right, I run linux, newest 
vpopmail and mysql. Anyone have similar probs. I also connect fine to the 
pop3 server
