My Service provider have just made some changes to the server and since doing so the admin copy emails are not sending out html.

They replaced their sendmail binary with a wrapper programme to help prevent spam. I assume something in that doesn't like the admin copies section of the zen script, however html is still being received for customer orders, new signups etc.

I take their point that html is clearly still available from the server so I'm trying to hunt down anything in the files that would make copy emails not html.

Hope that makes sense. Clues anyone?

thanks,
