How can I achieve that with hg, sorry I am not that familiar with hg. First "hg pull -u" and then?

During my recent testing most if not all postfix user checks failed. I can't remember how many, sorry, because I also had to clean-up my postfix configuration as well.

It had been status=undeliverable, thus mails didn't become delivered in my case. Only after adding "warn_if_reject reject_unverified_recipient" in smtpd_recipient_restrictions they became delivered.
