On a single domain VPS where I don’t manage any mail server or mailboxes (I just need the usual sendmail so my CMS is able to send notifications). During the Virtual server creation I unchecked(disabled):
- Mail for domain enabled
- Spam filtering enabled
- Virus filtering enabled
Still I see some mail servers running:
- Postfix Mail Server
- Dovecot IMAP / POP3 Server
- SpamAssassin Filter Server
Do I really need them and is it dafe to turn them off ?
Can it be “permanent” so they stay off if the server restart ?
