Thanks - I'd actually caught that one before reading your post (slight
hiccup with TB and news being slow getting through :-( ).
What I currently have is
# read in aliases that always mean spam
F{spamrx} /etc/mail/spamrx
LOCAL_RULE_0
# Divert known spam recipient address to a common mailbox.
# match fixed stuff
R$={spamrx} < @ $=w . > $: spam-rx < @ $2 . >
# match stuf with variable part, special-cased
R$+.ln1 < @ $=w . > $: spam-rx < @ $2 . >
R$+.ntl.com < @ $=w . > $: spam-rx < @ $2 . >
which actually does seem to do the right things, rather to my surprise.
I know the $: isn't strictly needed.

..... then finally
parse returns: $# local $: spam-rx
while
echo '3,0 x.ln1@remotelhost' | sendmail -bt -d21.12
gives
...
parse returns: $# relay $@ XXXX . XXXX . co . uk $: x . ln1 <

Ta muchly.

To answer my own question after a bit of trial and error, $$ seems to
mean a literal $. Weird it doesn't seem to be documented anywhere.
