Local domain name ,same as web domain

[domi1]

I have a strange problem sending emails to our local user on the lan(using outlook), if I send an email to lets just say to tom@web.com, that user will not receive the email and I think it has to do with a DNS domain issue?

our website lets just say is "web.com" wich is hosted by our ISP not internally and it has an ip address of "209.250.112.123"
(Also we're not hosting our own mail server)

and our local domain name server, for our network has the same name for its domain "web.com" its IP is
"192.168.0.1"

i tried a ping to "web.com" from the local workstation and its pinging the local server, I feel this is the reason why we're not able to send emails to anyone in our company?
also the emails aren't bouncing back, wich is weird

any help would be appreciated! thanks

Need to know more about your outlook config to answer question.

in your case you may need to add a new level of distinction to the email domain...such as mail.web.com....right now all internal users will always connect to the local DC/DNS servers because it has teh same name as your domain name....the reason it does this is because nothing would work internally without being able to toll web.com and have it resolve back to local resources...no logons could occur, group policy application will fail, etc.

if you add this extra extension on...or tie it in to your existing addresses anyway, than you could set up a HOST record in your current DNS zone for "mail" and set the IP to the external IP of your mail server....(the euqivalent call for the created host record would be mail.web.com which would resolve to an external IP and bypass your problem....this is your eaisiest route out with not hosting your own mail apps.
