Ok, if it's not serious and will still work then that's fine, as we have the
box 192.168.1.203 popping of of this mailserver.
Thank you, you have just put my mind at ease :-)

This is not serious. It just means that the pop daemon you are using 
cannot reverse resolve the client's IP to a hostname.

Do you have local DNS set up? If so have you set up a reverse resolution 
zone for that IP range?

Generally it would be a zone 1.168.192.in-addr.arpa. with PTR records for 
each IP in the zone pointing to the host name.
