No html in emails?

From what i can see from this thread this seems to be a very common problem!

What languages is your store running in? - English
What's the default language? - i think english how do i check?
What language is active when you're trying to send those emails? - English
Do you have any email templates set up for your specific language? - No

I also have MIME HTML set to true.

My emails show up as plain text even on preview, also even on a html allowing email address it still shows up as text.

Any ideas or any other information needing to be known before i can be helped?

Many thanks in advance

Ive tried playing around with settings, reading other threads and have still not found a solution.

:frusty: still unable to make any progress.

Maybe it's getting stripped off by your webserver.
Maybe the receiving email server is stripping the HTML off for their own reasons.

Are you sure it's sending in HTML format? ie: turn on email archiving and view the archived content that was sent.

What are all your settings in Admin->Configuration->Email Options?

What version of Zen Cart? What addons? What patches? Ever upgraded? From what version(s)? When?

Are you sending to "free" email services like yahoo/hotmail? If so, what happens if you send to a real traditional email account?

I've got two hotmail accounts. One of them get HTML emails. I have no idea why. Somebody knows about this problem with some hotmail accounts?
