From log:

Setting up postfix (2.9.1-4) ...

Postfix configuration was not changed. If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed. To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

This looks like a local configuration problem, rather than a bug in Ubuntu. As such, I'm marking this bug as Invalid.

Specifically, it looks like you have a problem with your /etc/postfix/main.cf or aliases files.

You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, and then change the bug status back to New.

Thanks!
