Installed the package in a VM, with default 'Internet site' configuration, it installed without problems. Sent email through it, email got delivered to local mailbox (/var/spool/mail/<user>).

Removed package, installed the last one from updates/security (2.8.2-1ubuntu2.1), then did an update to 2.8.5-2~build0.11.04 from -proposed, seems to update OK. Not sure why it's stopping twice, but I guess that's normal.

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'.
