I recently “Transitioned” to Exchange 2007 on a Windows 2003 server and everything works fine with the exception of my MAC users using Apple Mail. I’m using IMAP and they seem to connect just fine during setup and it also allows them to receive email just fine. The problem seems to arrive when they attempt to send emails to individuals outside of our windows domain. I don’t have this problem with any of my Outlook or OWA clients, this is only happening with the Apple Mail clients. I’m also using ISA 2006 but i don’t believe i have any issues there. Any help would be appreciated and thank you in advance.
The following are the two messages clients are receiving when attempting to send email from the Apple Mail client: “The server “xxx.xxx.xxx.xxx” rejected the address “email@anotherdomain.com”. The other message states: “Sending the message content to the server failed”. Once again thanks in advnace.
