Thanks for submitting this bug.
The log shows
newaliases: warning: valid_hostname: numeric hostname: 04 newaliases: fatal: file /etc/postfix/main.cf: parameter mydomain: bad parameter value: 04
Is your hostname in fact '04', or did postfix manage to pick up the wrong name? What does running 'hostname' show?
