I am switching one of my small Virtualmin boxes' mail needs over to free Google Apps' mail. No virtual server will need local mail. I just wonder if it is ok to completely turn off, ideally to delete the following services:
ClamAV Virus Scanning Server
SpamAssassin Filter Server
Postfix Mail Server
Dovecot IMAP / POP3 Server
What other mail related services and scripts I could remove from my Ubuntu 10.04 server not to break anything on Virtualmin?
