html in e-mail / NeXT stuff

I don't suppose exchange has any sort of built-in SMTP autoresponder (or anyone know of an autoresponder address anywhere?) - be nice to be able to send emails out to an SMTP-only site and get a reply back just so's I can check that I *don't* have any stupid formatting in my outgoing mail... it bugs the hell out of me that I'm forced to use exchange here at work; I'd rather not use all the 'extensions' that exchange gives you - all of them being unnecessary - but the software's very good at not making it clear what a sent message is going to look like at the other end of the wire... (give me standard SMTP and uuencode any day! :) (apologies in advance if this comes out with strange indentation, formatting and useless attachments... at least I don't think I'll have squeezed any HTML in there... :*) oh well, rant mode off... sorry for the off-topic!!
