Multipart e-mail customization

I use the e-mailing capabilities of ISY to send myself an e-mail to ##########@tmomail.net. This gives me an SMS notification. A problem with T-Mobile's SMS is that the message comes from a random number making the messages impossible to organize. I have read on the internet (including on this forum) that T-Mobile switches the message to MMS after 160 characters which gives a much better experience on the phone -- I see sender, subject, etc. However I think this must have changed because through trial and error I found T-Mobile switches to MMS at around 400 characters now. Basically my e-mail customizations are padded with ". . . . . ." and this is a terrible phone experience. Using HTML-only or XML-only is not an option for me because tmomail.net only reads text/plain messages, and anything else appears to my phone as an SMS with no content.

I have noticed, however, if sending from GMail, even a very short message appears great on the phone. I have been able to determine the reason for this is because the Content-Type of the e-mail from GMail is multipart/alternative with a boundary. As soon as T-Mobile encounters this, they switch to MMS and deliver the text portion (even if the entire e-mail request is less than 160 chars). I was able to prove this using .NET's SmtpClient class.

So my (selfish) request is that ISY e-mail customizations support multipart/alternative (basically a combined template of Text and HTML). Even if the HTML portion of the customization is empty, as long as boundaries exist in the body of the message everything works great with tmomail.net.

Thanks
