Sure thing.
In yer' RCPT ACL:
discard senders = :
# if you don't want to be rude, detect if the recipient is a catchall.
# if catchall has a separate router, add sumthin' like:
# "address_data = catchall" (and "address_data =" in other routers)
# in yer' catchall router.
domains = +local_domains
verify = recipient
condition = ${if
eq{catchall}{$address_data}}
message = Yummy!
Not tested, though.
