Well shucks (expletive replacement), I have tried about every combination possible. I must say my hosting is quite tolerant of just about all of the settings I have tried. Sends emails out just fine, just not in HTML. This is certainly not a crisis, as long as emails are sent, confirmations, orders, etc. I just believe HTML emails look more professional. Thank you Chuckl for all of your help. If someone stumbles across this thread with another idea, please post.
