URL modification fails and message stored in bad message queue

Products

• Messaging Gateway

Issue/Introduction

Messaging Gateway (SMG) has been configured to take the Modify URL action on some messages but is generating alert emails indicating that one or email messages has been stored in the Bad Message Queue.

Message Audit Logs show the message status as "Processing".

Reviewing the Brightmail Client logs shows the following errors:

2022-07-06T17:27:32-07:00 (INFO:12826.713750272): [46022] Transforming message with MTE action Clicker.
2022-07-06T17:27:32-07:00 (WARNING:12826.713750272): [46037] The message body could not be decoded from quoted-printable format.
2022-07-06T17:27:32-07:00 (ERROR:12826.713750272): [46039] Could not copy the message body.
2022-07-06T17:27:32-07:00 (ERROR:12826.713750272): [46059] Unable to modify URL's in message body: Error 46039.

Cause

The email message data contains quoted-printable encoded data which cannot be properly decoded for URL modification

Resolution

This issue is addressed in SMG 10.8.1 by defaulting to a less strict decoding of the quoted-printable encoded message data.
