Messaging Gateway

Issue/Introduction

Messaging Gateway (SMG) marks all messages as being Unscannable for Disarm after it runs uninterrupted for an extended period of time. The issue that is described in 'All messages receive "Unscannable for other" verdict' is similar. But it has an underlying cause that is not addressed in version 10.6.3.

Resolution

This issue is addressed in SMG v10.6.5.

Workaround

Restart the MTA process from the command. The restart causes Messaging Gateway to recreate the temporary space that is allocated for Antivirus (AV) scanning. Alternately, the SMG system can be restarted.

smg> service mta restart
