Messaging Gateway

Issue/Introduction

Some messages that pass through the Symantec Messaging Gateway may end up garbled with high ASCII (eight-bit) characters, or with some extra lines added to the body of the message, when delivered to the recipient mail box.

Cause

The message corruption is being caused by a misplaced MIME header which can cause a conflict in the structure meant for rendering the message. This is most often seen with the addition of the SPF check header, which is likely to be pushed into the body of the message when this issue occurs, but it can occur with other headers as well.

Environment

Messaging Gateway 10.6
