directions to control delivery. Specifics are left to the
implementation, but there are a few common keys:
* envelope_sender - the email address of the RFC 2821 envelope sender;
* decorated - a flag indicating whether the message has been decorated
with headers and footers yet;
* recipients - the set of all recipients who should receive this
message, as a set of email addresses;
