$@ is explained in doc/op/op.*
If you refer to check_* rulesets then see the same document.
5.1.4. Ruleset hooks
A few extra rulesets are defined as "hooks"
that can be defined to get special features. They
are all named rulesets. The "check_*" forms all
give accept/reject status; falling off the end or
returning normally is an accept, and resolving to
$#error is a reject. Many of these can also
resolve to the special mailer name $#discard; this
accepts the message as though it were successful
but then discards it without delivery. Note, this
mailer cannot be chosen as a mailer in ruleset 0.
-> It doesn't matter what's after $@, I could as well have
used "42", "Kilroy was here", or "It's a kind of magic",
but "OK", "OKSOFAR", "RELAY", etc seem to make more sense
:-)
