12 Yup. If you've got mail DNS records pointing at your home server,
13 incoming mail shouldn't be a problem and your vps admin can't snoop :-)

22 Can't you tell your server to forward all outgoing mail to your ISP's
23 SMTP server? That way, you don't have to worry about all the spam

27 outbound requires a dedicated eavesdropping solution and if they're
28 going to do that they can always snoop ANY outgoing SMTP.
