A while back I had a similar problem. The problem went away, but I don't know how/why. It started when I switched from my 8703e to my 8830. I would be using the browser searching for sale items on Craigslist. I would click the link to send an email. My default email would be sent using my Gmail account. Randomly someone would respond back saying the couldn't read my email. In their reply I would see a bunch of gibberish in my email. When I would look on the Internet at my sent mail in my Gmail account, it would look fine.
