after deploying SMG to the company last week, we've discovered a few emails that open blank after being processed by SMG. The culprit appears to be the signature-on-top code which somehow misinterprets the HTML email as text-only, and puts the text version of the signature in the html with incorrect tags. This renders the entire email undisplayable and it shows up blank.
Here's the beginning of such an email:

See where the on-top signature is added? that is the TEXT version of the signature; the HTML version is different.
This might be an issue if the email doesn't have a TEXT portion?
No, I've not opened a case yet, just discovered it a few minutes ago and wanted to see if anyone else is seeing this. I'm too busy with other tasks this morning to open a case, but will get to it this afternoon.
