From terminal log:

newaliases: warning: valid_hostname: numeric hostname: 04.3
newaliases: fatal: file /etc/postfix/main.cf: mydomain parameter: bad parameter value: 04.3
dpkg: postfix package processing error (--configure):

Thank you for taking the time to file a bug report.

Looks to me like it died trying to read the hostname of "04.3", which
is all numeric.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'.

However, if you believe that this is really a bug in Ubuntu, then we would
be grateful if you would provide a more complete description of the problem
with steps to reproduce, explain why you believe this is a bug in Ubuntu
rather than a problem specific to your system, and then change the bug
status back to "New".
