From: Jake Ballamis on

I have a handful of users (included the CEO) who are experiencing a very weird issue with Entourage 2008 (All on varying patch levels) and Leopard/Snow Leopard with Exch 2K3 SP2.

In a nutshell, these users are having an issue in which they will receive an email from a sender that will prevent the user from sending or receiving email.

I can't tell you anything that's common between the senders, as they're all pretty random. We're even seeing this issue with senders that have been fine in the past.

The only commonalities that I see between the recipients is that they have the same SMTP address, they are all using Entourage 2003 and they are all connected to the same Exchange server.

Occasionally we'll see an error message, but it's never the same error message. Sometimes the errors will be related to the Calender, other times the will be related to non-roman characters. (We did apply a hotfix to the Exchange server for this.)

The only thing I can think of is that there is something with the message header?

I am posting the header from one message that was a culprit to this issue to see if anyone has ideas or suggestions (the domain names and public facing IP addresses have all been altered):

I was advised on the Mactopia site to try posting here to see if anyone had suggestions.

Any help is appreciated.
