gtk-gnutella is very slow on my linux machine. It tries and fails to resolve the local machine: on startup I get error messages saying:

03/07/17 20:43:52 (WARNING): cannot resolve "phrenia": Unknown host

I know I could add "127.0.0.0 phrenia" to
/etc/hosts, and this helps. However, this confuses sendmail, so that sending a mail takes 3 minutes.

Is there a solution to this dilemma?
