Exceptions to regex rules in BCC maps are best made via conditinal
patterns, not by creating BCC to discarded recipients.
foo.pcre:
if !/exception/
/rule/ recipient
endif
If one does want to discard a recipient, go with:
transport:
discard.invalid discard:silently
Tnen any recipient i @discard.invalid is dropped much more efficiently
than doing a delivery to "/dev/null" via local aliases(5).
