sendmail - reverse lookup problems

another odd problem with reverse lookup's. we are able to send mail to
na.bestfoods.com [188.8.131.52]. They cannot send mail to us. They can do
an nslookup and get our mx record. Sendmail, on our end, I think is timing
out trying to reverse lookup their outbound mail server. They tell me the
server is 184.108.40.206. when i do an nslookup 220.127.116.11 i get nothing.
when i do a dig -x 18.104.22.168 it reports that att.net is authoritative for
their domain, and the PTR record is aliased? i think.
why is nslookup showing nothing
why is sendmail choking on an aliased PTR record? Should it be choking?
