Yes. The output of
makemap -u hash access.db >access_dump
18.104.22.168 OK # xsmtp02.mail2web.com
It is there.
After a lot of research I realized I am using two features that muck
with the check_relay ruleset. The DCC hackmc script to make DCC
understand about whitelisting from the access database and
FEATURE(`require_rdns2',`forgedignore')dnl which requires the relay to
have a rDNS. This changes the usual check_relay code albeit I haven't
figured out how it can generate a 553 error code along with an OK.
