I just realized that I started having problems with the Contact section. Now two things that I have done recently is I updated Mambo to version 4.5.1.0.9 and I added a recommend us section. In order to make the recommend section work I had to go into recommend and change a 1 to a 0. So that users could send to other users. (However I don't think this is the problem since I have now uninstalled this and still having my problem.) Now if I go into contacts and change the email address to lets say my hotmail account I do get email that way but if I use email address with our domain name which is erniewilliamsltd.com I do not receive any mail at all.

If there is now problem with the Mambo or the coding in Contacts then I think it might me a problem with our exchange server or a problem with the company that we use to catch a lot of our spam?

Please HELP!
Thanks Zirby
