Am I right in assuming this mod doesn't send email using the Multipart/Alternative MIME format? - there's no facility to include a plain-text alternative version of the email.

More on this format:
"You need to send HTML email from your server in “Multipart-Alternative MIME format.” Basically, that means your mail transfer agent bundles your HTML code, PLUS a plain-text version of the message, together into one email. That way, if a recipient can’t view your beautiful HTML email, the good-oldfashioned plain-text version of your message is auto-magically displayed. It’s kind of a nerdy gobbledy-geek thing, which is why a lot of people mess things up when they try to send HTML email themselves. You either need to program a script to send email in multipart/alternative MIME format, or just use an outside vendor to deliver things for you."
