I had to setup a new email client on my laptop tonight and that required I send some emails from one account to another to test the settings (colors, fonts, signatures, etc.). I would basically send an email from one account in a web browser, and reply from the other account in the email client. The below is cut and pasted from that thread. Keep in mind I was EMAILING WITH MYSELF.

Account #1: Testing Apple Mail
Account #2: Looks good, loser
Account #1: No way bugga. Whachu talkin’ about. Crazy emailin’ foo.
Account #2: Oh, no you dinnit! MMMhhmm look at all those pretty colors!
