problem with mail()/html/outlook

I'm trying to send an html email via a php script, but I'm running into a rather bizarre problem. I can get it to send the email just fine, but when it is read on windows Outlook (macintosh outlook express are unaffected) clients, it strips two characters after any '=' signs, so it plays havoc on the html it tries to send: <div align="center"> <table width="570" border="0" cellspacing="0" cellpadding="0"> becomes: <div align=enter"> <table width=70" border=" cellspacing=" cellpadding="> Now, I'm sending all the right headers, I think: $headers .= "Content-Type: text/html; charset=iso-8859-1\n"; I've read up on this as much as I can and it works for every other client other than MS Outlook under Windows. Unfortuantely, that's a rather large percentage of people that are going to get a foo'd message of mine. I know that there are certain mime characters like '=2D' that mean certain things, could it be that i'm not sending the right header and Outlook is interpreting a differnt mime type, therefore munching lines as it parses them?
