Situation
All html messages to and from the internet when read, have a message body that shows blank. Plain text messages show fine.
Resolution
The issue apparently was caused by a corrupted "preamble.txt" file in the GW-Domain\wpgate\gwia\ directory. It had garbage in the file, and once the file was restored from backup from before the problem started, the problem went away.
Cause
The customer had a spam blocker process or appliance that fronted the GroupWise Internet Agent (GWIA),
apparently once the spam blocker saw the garbage in this file it put it spam tags in the mime that was contributing to the issue. This is an example of the portion of a problem messages mime that when removed, resulted in the problem going away:
Content-Type: multipart/mixed; boundary="=__PartC7F2A1CF.2__="
X-DLP-ENABLED: 11.111.111.1/11
