Why can't you sort on the "To" headers?  E.g.:

(setq nnmail-split-methods 'nnmail-split-fancy)
   (setq nnmail-split-fancy
     '(| ("to" "your-e-mail-address@yahoo" "mail.yahoo")
         ("to" "your-e-mail-address@lycos" "mail.lycos")))

That won't snare e-mail not addressed to you, or if it has a
suppressed recipient list; I suppose you could substitute some kind
of regexp for your e-mail address, or let them go to mail.misc.  Or I
suppose you could do some sort of matching on the "Received by"
header, which ought to be specific to the ISP.

That's exactly why. I'm trying to keep track of which account spam
comes from (so that I can dump the throwaway accounts when they become
too full of spam). And spam regularly has mangled "To" headers.

Might look into received by. I'm not sure about this one.

I already use spambayes if I want to filter spam. The problem here is
a little different. I've set up a throwaway mail account, and I want
*all* mail from that account in the same group - both spam and
non-spam. I'll then monitor that account, to see how fast the ham:spam
ratio gets silly. (I want to see what particular acts generate spam -
using the address in a mailing list, using it on Usenet, posting it on
a website, etc etc)

That was what I was hoping might be possible, but I also have no idea
if it could work. There certainly isn't a "mail-source" header I could
use...

Thanks,
