My answer would be "yes". Some automated RBL removal procedures require
you to receive mail for postmaster@[BLOCKED_IP]. Also, it is required
for RFC compliance and it should do no harm.

I have this is RCPT ACL:
# Always accept mail to postmaster, for
# both our domains and the systems IP literals.
accept local_parts = postmaster
domains = +relay_to_domains : +domain_literals
And a router:
# route postmaster@[IPLITERAL] to postmaster
postmaster_ipliteral:
driver = redirect
data = postmaster
local_parts = postmaster
domains = +domain_literals
/tom
