Thanks for those replies from Jor-el, Gregory and Martin. But the solutions Jor-el and Gregory had proposed did not work for me, so I has to the some RTFM.
THE PROBLEM I installed netscape and was trying to configure mail. I have exim installed and configured for internet site, uses SMTP. I tried to configure localhost as the outgoing smtp server. Exim kept refusing connection requests to the SMTP port from netscape, as if mail relay requests from clients on the localhost was not allowed. THE SOLUTION I decided I must allow mail relaying for localhost. Checked /etc/exim.conf and found: # The setting below locks out the use of your host as a mail relay by any # other host. See the section of the manual entitled "Control of relaying" # for more info. sender_host_reject_relay = * So this means mail relaying is disabled, even for the localhost ?!? So after doing some RTFM, I decided I will add the following line to /etc/exim.conf sender_host_reject_relay_except = localhost And now, finally everthing is working fine. Just wondered, is there any gain from disabling mail relaying for the localhost by default?
