My server is server.workgroup.domain.local. My website is
domin.com. Public external DNS servers host my www record
that point to my external web host's site and a MX record
that points to my SBS Exchange server. My users tell me
that certain people from certain domains can't send them
emails successfully. How do my DNS records and zones need
to be configured to allow external email servers to find
and resolve my mail server? Currently I have a forward
lookup zone, workgroup.domain.local that has the SOA and
host records for that zone. There is also a reverse lookup
zone for my subnet. Do I need to add a forward lookup zone
for domain.com and add host and MX records for my mail
(SBS) server?
Thanks :)
