Our sites stopped sending our pre-formatted XML emails to our Call Center yesterday. We recently moved all of our sites to new Web Servers that are defaulted to .net 2.0 settings. We have a number of sites that are still 1.1. Since the move, our 1.1 sites have stopped sending emails to our call center but our 2.0 site has not stopped sending emails. If I change our call center email to our COMPANY EMAIL domain and recompile on a 1.1 site, i receive the email as it should go through. If I change it to a Hotmail account or some other email, it does not go through.

 This sounds like an ISA problem but our SYS team does not believe so. Maybe it was the network Gnomes?

 Any help is greatly appreciated!
