Short answer: you can't. Also, HTML Email is incredibly annoying. And you know what's even *more* annoying? HTML Email that is sent with a text/plain MIME type, indicating it's not HTML. Fix your mail client, it's very rude. --=20 | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
