Using DNS to route email
John
Hi
What do I need to use DNS to route email apart form running the Inter
Connection Wizard? In the past I have always forwarded emails to a named
smtp server so am not aware how using DNS works in this scenario.
Thanks

You aren't routing mail via DNS - what's happening is your server is
communicating directly with the recieving servers - DNS comes in
because it has to look up the recipient domain's server info via DNS.
Really, you don't need to do anything at all - if you have a static
public IP and it has a valid PTR (reverse lookup record...ask your ISP
to do this) it just works.

You run the wizard and it just works.
However Make sure you have a PTR Record first.
(Reverse DNS Record.)
You can see here!
http://iptools.com/
Put in your IP in the Reverse DNS look up
If you don't see a Reverse DNS name you will need one.
(Example you can't send anything to AOL with no Reverse DNS record (PTR))
If you do not have a PTR Record call your ISP and Ask for one
If the person on the phone doesn't know what one is
tell them to hand the phone to someone who knows what one is.
(you should not have to tell them what a PTR Record is.)
Have them Create mail.yourdomain.com (or what ever your current MX Record
is.)
(To find out your MX Record MXToolbox.com )
Also you should check if you are on any BLACK Lists There.
If you are, on a Black list
IMO it's just best to stick with using the SMTP from your ISP or where you
host
then they have to deal with getting off the black list not you.

Thank you for letting us know it helped, but this newsgroup has been
abandoned by Microsoft and only a few people still keep an eye on it.
These days the action is at:
http://social.technet.microsoft.com/Forums/en-US/smallbusinessserver/threads
Russ still posts there and will be pleased to know this, as I don't
think he's one of those who read this newsgroup.
