Re: your followup.

You have several choices, but adding ^[^@]+@(.*\.)?nyc\.gov$ to acceptable
aliases isn't one of them.

The post was held because it wasn't explicitly addressed To: (or Cc:) the
list. I.e. the canonical list posting address, say <email address hidden>,
was not in To: or Cc:. Maybe it was a Bcc: to the list. Maybe the post was
addressed to <email address hidden>.

If the former, and you can't convince to poster to explicitly address the
list, then you have to turn off require_explicit_destination. If the
latter, you can add <email address hidden> to acceptable aliases.
