One thing I'm not clear on is whether any tests look at intermediate stages of decoding. That is, if a message has a base64'd HTML body, I think "rawbody" sees the base64 and "body" sees the rendered content, but nothing sees the un-rendered HTML. I'd be glad to learn I'm wrong about that. > 2. specifically check for those nasty "workarounds" since they are a spam > indicator per se. That's already done in many cases.

Yes, SA does this. The problem in this instance was that the message contained <frame><noframes>garbage</noframes></frame> which (I suspect) SA's HTML renderer reduces to "garbage" whereas (e.g.) IE's discards the entire thing as nonsensical. ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
