sudo creates a mail if there is some problem with the authentication,
which explains the initial error mesage. Perhaps more things in startup
use sendmail, and thus they all fail because of this?
I guess it's questionable in the first place why you installed postfix
on a desktop box if you don't use/configure it, but I guess it was
installed as a dependency of something.
I'm not sure whether it would make sense to fix postfix to gracefully
fall back if main.cf doesn't exist. I guess it wouldn't; my advice for
you is to boot rescue mode, apt-get purge postfix (if you don't need
it), and restart again.
** Changed in: postfix (Ubuntu)
Sourcepackagename: sudo = postfix
