OOPS, As I stated above, I now have Saved Sent Mail DISABLED By DEFAULT. I had it that way for DAYS before I was actually able to get it to be DEFAULT for ALL of my Valued Users.
I see some progress here...
As stated above, I currently want to know how to get the Email Messages Footer (Global Signature) to NOT show up in ALL CAP letters when Plain Text Email Users view Emails sent from my web mail services. It shows up GREAT for HTML Email Users. :--)
So, you'll get a response, but keep working on not using upper-case everywhere
Back to your question. I suppose you're using <strong> or <b> in HTML signature. So, the content of these tags is converted to upper-case by html2text class. To change this behaviour you'll need to modify html2text class (program/lib/html2text.php file). See method _preg_callback().
