RTFM! From man 8 popper:
... The popper pro-
gram initializes and verifies that the peer IP address is
registered in the local domain, logging a warning message
when a connection is made to a client whose IP address
does not have a canonical name. For systems using BSD 4.3
bind, it also checks to see if a cannonical name lookup
for the client returns the same peer IP address, logging a
warning message if it does not. ....
