If you're not going to serve email and your not going to use email addresses in
the linuxlighthouse.com domain then you don't want to define MX records.
MX records are "Mail eXchange" records and are specific to email.
Normally email addresses are "domain" addresses as opposed to "host"
addreses.
So, you'd normally want your email address to be e.g. "j...@linuxlighthouse.com
<mailto:j...@linuxlighthouse.com>".
But you don't have an MX record for your domain. You have it for a host.
I actually have a host to serve this IP number so this error too must go
You do want an IP address for the "domain host" since you do want to service
http://linuxlighthouse.com
what's 'not clear to me is how I can expose that host/ip through my firewall
configuration but in either case I want to get this MX configuration correct
Again, not using @linuxlighthouse.com email addresses.....no MX records should
be
defined.
This recursion option has been turned off right now , thank you for that
See another post in the thread about this.
It's definitely misconfiguration. in this case there's nothing on this side of
the firewall that any attacker would want :(
That may not be "true". If, for example, your web server is badly configured
or otherwise lax in security it could be
used as part of a phishing expedition.
