I am using Exchange 5.5 sp4 and I am trying to forward email to an Internet email account. I created a hidden Custom Account for an Internet email account. I set the delivery options in the exchange account to send to this internet account and keep the messages here. It worked for about two months and now I am getting a message stating that the delivery was not made. I used a hotmail account and sent in email straight to the account and it went through. The account I am sending to is a palm.net account.
