BES 220.127.116.11 for Exchange. Using Exchange 2003 SP1 with Intelligent Mail Filter & Outlook 2003 SP1 clients. IMF and client side spam filter are the current versions.
When I wirelessly activate a BlackBerry from BES, several encrypted e-mail messages from
(where ?? is a 2-digit number between 01 and 08) arrive in the user's mailbox. All are placed in the Junk E-mail folder by IMF, which means (based on our IMF settings) that IMF is assigning them an SCL of 3 or 4.
The messages all begin with "This message is used to carry data between the BlackBerry Handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server," so I gather it's IT Policies or Service Books or something destined for the BlackBerry.
Once the BB is activated, I don't see the messages in the Inbox or Junk E-mail folder any more, but examining the logs, I can see they continue to be received, so after activation, they evidently then have an SCL <3.
We're whitelisting etp??.etp.na.blackberry.net to work around it, but not satisfied with that solution as RIM could change it without notice.
Anyone else seeing this?
