I got to experimenting with the $RECIP thingy and I'm at a loss.
$RECIP seems to work and RECIP seems to fail for me
You're not using the same test that the ISP is using.
The parse of
* $RECIP ?? pattern
is approximately
* Begin a condition
$ The pattern part of this condition will contain variable expansions
RECIP Token -- might be part of the pattern, might be a variable name
?? Preceding token is a variable name, rest of line is the pattern
Note in particular that $ is not part of a token "$RECIP", it's an
introducer like "!" (for a negated test) or "?" (for a test against an
external process result). When you used it in
* $RECIP ?? ^^perl(_at_)$DOMAIN
you need it, because you have a reference to $DOMAIN in the pattern
(and I presume you are not trying to match "perl@" end-of-line
"DOMAIN"). The ISP did not have any such reference in the pattern
part, and therefore didn't need it. The fact that both you and the
ISP wrote this as
* $RECIP ?? ...
(no space after the $) rather than the clearer
* $ RECIP ?? ...
merely points out that neither of you really understands what you
wrote, which worries me in the case of an ISP. They might later
insert a $ into the pattern expecting it to mean end-of-line, and
instead it would be taken as part of a variable reference.
