Webmail login not working
 

I am running CentOS on a dedicated server, and webmail was working fine up until this morning. Now when I try to access squirrelmail or horde, it just keeps prompting me over and over for my username and password. It never says its wrong, and I know its not. It will not transfer me though. I'm stumped. What gives?

I don't have an answer, but are your logs showing authentication attempts? Is your mail server properly up and running?
