We're using Google Apps to handle all e-mail for the domain, so we have no need for POP and IMAP services running on our server (and I'm always getting e-mails from LFD that show bots are trying to connect with random passwords and such) so I want to disable them, but keep SMTP active since some scripts running on our server use it and I don't feel like rewriting them right now.

I unchecked IMAP and POP in the WHM service manager to disable them, but it's still enabled and I'm able to connect and everything. How can I completely disable these 2 services? Thanks
