Strongly Suspect Feature in Symantec 11.07 is the Culprit

HCL Notes/Domino 8.5 Forum (includes Notes Traveler)

Subject:

After considerable searching I've concluded a new feature in Symantec 11.07 is the culprit. A feature was added in Notes Auto-Protect to cache scanning results on attachments, so that emails with unaltered attachments could be sent without redundant scanning. The fields create no problems in the Notes client, but some (not all) emails with these fields cannot be read in iNotes. What clinched it for me was a test done with a co-worker, who sent the same message twice, with and without Notes Auto-Protect enabled. The errant fields were only found on the message where Auto-Protect was on. We are shutting down Auto-Protect, as the iNotes issues are a serious problem for us.
