I started by using telnet to send a local message (i.e., `telnet localhost 25`) and then checked Postfix's log file (i.e.,/usr/local/psa/var/log/maillog) to verify that the message was delivered: Nice :)
As I can see currently the site is up and running. Did you fix it already? As for the "reconfigurator crashing", could you please send the error of this crashing?
