	Sendmail cannot resolve the IP address. While this can be a
DNS configuration issue (an error in or a missing in-addr.arpa
zone file), it is commonly the result of one's upstream not
delegating authority for the in-addr.arpa zone for the IP addresses
they assign to their downstream. The result is that while the domain
will resolve to an IP address, the IP address will not resolve to a
domain name (reverse lookups will not work).

	There are some issues that primarily apply to email (some
servers may refuse email - in violation of the applicable RFCs
I might add) and thus the situation should be corrected however, for
the most part, this error isn't worth loosing any sleep over.  

	Peace be with you,
