[SA-exim] Side-effect involving mailing lists

Clearly, I should have spent more time reading
/usr/share/doc/sa-exim/README.gz (where you warn about all this), but
was in a hurry because my Exim3 & SA setup was collapsing under spam
load, so I converted it under rather stressed conditions.

Off the top of my head, I'm not sure how to write an exim parseable
statement that equates to "if Received line has .grp.scd.yahoo.com in there", 
but that's my problem.  Hmm, probably: 
{!eq {$h_Received:}{^.*grp\.scd\.yahoo.\com.*\$}}

I wouldn't want to whitelist everything whose Received headers claim it
to have originated at Yahoo, I think.

Oh, and I wanted to say _thank you_ for sa-exim.
