I'm trying to offer my Cpanel email users a service like hotmail... but the only problem is that I can figure out how to prevent them from checking their email accounts through POP. I only want them to be able to use Horde.
best thing is that you block the dmoan port in a firewall
so anyy request comeing to pop3 port for that domain will be blocked.
it may help if you assign a saperet ip for that domain so you can have multi rules for it with out effecting your other domains.
