Thanks for the openspf mention. I think you have guided me there before. The Iphone I think I am going to make them log in OMA/OWA and get there mail that way I know the routing in from behind my firewall. I just need to get it up and running.... But not until I have the rest of yesterday's list up and running correctly.

(from http://www.openspf.org/SPF_Record_Syntax) So rather than specifying your mail exchanger's name or IP address in the SPF record, you can just specify "mx". Reason it's a good idea to be explict during your migration is that your MX records will be in flux. On Tue, Mar 30, 2010 at 1:28 PM, David W.

It's not a question of the iPhone, but how mail is routed. Can the iPhone be configured to relay mail through your systems? If so, do that, problem solved. If not, you're SOL. -- Ben
