I do not need a solution (just sharing information)
In version 9.4.45 and 9.5.3, the X-Brightmail-Tracker message header was chunked into nice short pieces (i.e., less than 80 characters).
In version 9.9.13, the X-Brightmail-Tracker message header is no longer broken up into short pieces.
X-Brightmail-Tracker: H4sIAAAAAAAAA+NgFmpjkeJIr... and so on for 802 characters.
This is causing us some grief.
Can you confirm that this was a deliberate change and tell us in what version the change occurred?
Jack
