The Messaging Gateway (SMG) Disarm feature may be configured to strip various types of content from PDF attachments including fonts. In some cases, SMG 10.6.3 is stripping fonts from PDF attachments during Disarm processing even though font stripping is not enabled in the configuration. This results in PDF text content appearing as a series of variably sized dots rather than the expected text.

Disarm processing is stripping fonts from PDF attachments even though configuration shows font stripping as disabled.
This issue may be addressed by applying patch 268 to SMG 10.6.3 or by updating to SMG 10.6.4.
