nc works as well as telnet Postfix is hanging upon connecting to port 25 I narrowed down the problem to this config value: smtpd_sasl_auth_enable = yes When that value is enabled, connections to port 25 get no answer. Actually the first one is closed quickly, and the second connection hangs indefinitely. > >Here is the WORKING "postconf -n" (sasl_auth disabled), > > next time, show 'postconf -n' for the non working setup.
