I found that the postfix /etc/postfix/access file allows you to specify
domains that can't send you email (for instance, I reject anything from
*.com.cn), but it also prevents you from sending email to those domains.
So it's possible that a locally created email would not trigger any
incoming mail filter but would trigger those same filters on the outbound.
