another odd problem with reverse lookup's.  we are able to send mail to [].  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   when i do an nslookup i get nothing.
when i do a dig -x it reports that 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?
