It's a bit tricky because you're trying to find the email address in the
address file, rather than match one of many patterns in the address file to the
email.  If you use the latter approach you should be able to put whatever
patterns you want, including just the domain.

  patterns = File.readlines "/path/to/my/addressfile"
  patterns.each do |pattern|
    if message.from.email =~ /#{pattern}/
      message.add_label :somelabel
    end
  end

If you take this approach then you should be able to have lines in your
addressfile like ‘foo.com’ (sans quotes).  This will actually match a little
more than what you probably intend (e.g. it would match emails from
foo.com@bar.com or even joe@foodcom.net), but is likely good enough and saves
you from having to learn regular expressions.
