Subject: Re: [9fans] warning of putchar

it's a good stop-gap. i'm pretty sure the hueristics like this do
not work, in general.

the most consistant indicator of spam is the structure of the 
Recieved lines. unfortunately, i have yet to figure out how to
write a set of rules for recieved lines that's 85% effective.

maybe the real problem is that spam is like porn. "i know it when
i see it." ;-)

| Ah, that explains it.  My approach to spam curbing consists of dumping
| unknowns to a folder in Cape Town and forwarding to my home only
| summary headers.  Occasionally, I spot mail from a desired source,
| otherwise I check the folder on a whim.
| 
| It's not ideal, but it does diminish my frustration level without
| depriving me of important mail.  Now to figure out how to use the
| notification as a remote mechanism to prompt forwarding or discrding.
