[Mimedefang] DNS and MX records

[netguy]

Hi all

Please tell me that I am NOT weird?

Receintly I updated DNS for a few domains.  My registrar gives the 
option of assigning an IP addy for domain.tld without having an alias: 
mail.domain.tld  Ok, says I, lets give it a go.  Bam!  Slam, Spam 
started invading my privacy.  This leads me to believe either:
    1. Mail ( spam ) in this case is being sent to domain names without 
doing MX lookups.
    2. I screwed something up.

So I went in and unassigned that IP from domain.tld and that Spam stopped.

Will look into this further to make sure that I have the domain setup 
proper.
