After numerous posts on the Apple Discussions site and spending 4 hours one afternoon with the "geniuses" I still can't send email from the SMTP setting for my Exchange account. I've literally tried everything, IMAP is turned on on the office server, we use MXLogic for upstream/downstream filtering but the IP address is the same as it is for our network. I'm beyond frustrated. Is anyone else having issues with SENDING mail via their Exchange server settings? Hotmail and my .mac account send and receive just fine. I've had to "send on behalf of" with every email that I respond to viw the work Exchange server and it's pretty ridiculous. At the apple store, I used the same exact settings in their Entourage account that I use in Mail and it IMMEDIATELY connected and allowed me to send. I'm just not real fired up over spending $150 for bloated MS software when I've been operating just fine without it. PLEASE LEND A HAND! Thanks!
