So I've setup a windows 2003 server with exchange server 2007 and set zoneedit.com to act as my dns servers. I setup a subdomain under godaddy as mail.mydomain.com and created an mx record of mail.mydomain.com and (a) record to mail.mydomain.com Now i'm trying to access it through the iphone and when it asks for server I put in mail.mydomain.com and it doesn't work. I believe it can find the server because it asks to verify ssl certificates but I just can't figure it out. // EDIT: Got this part to work. Now if someone can help me get the sending and receiving email part of it to work... I opened all ports on my router just to eliminate port configuration problems. If anyone can help me with this it would be very appreciated.
