Hi,

This hook is useful to use different names/addresses depending on the
destination address, subject, etc. of the message. Example:

  if header["To"] and header["To"] =~ /^sup-(.*)@rubyforge\.org$/
    Person.from_address "Michael Stapelberg <michael+sup@stapelberg.de>"
  end


Best regards,
Michael
