* A parenthesized list that describes the envelope structure of a

* fields as necessary.
*
* The fields of the envelope structure are in the following
* order: date, subject, from, sender, reply-to, to, cc, bcc,
* in-reply-to, and message-id. The date, subject, in-reply-to,
* and message-id fields are strings. The from, sender, reply-to,
* to, cc, and bcc fields are parenthesized lists of address
* structures.
*
* An address structure is a parenthesized list that describes an
* electronic mail address. The fields of an address structure
* are in the following order: personal name, [SMTP]
* at-domain-list (source route), mailbox name, and host name.
*
* [RFC-2822] group syntax is indicated by a special form of
* address structure in which the host name field is NIL. If the
* mailbox name field is also NIL, this is an end of group marker
* (semi-colon in RFC 822 syntax). If the mailbox name field is
* non-NIL, this is a start of group marker, and the mailbox name
* field holds the group name phrase.
*
* If the Date, Subject, In-Reply-To, and Message-ID header lines
* are absent in the [RFC-2822] header, the corresponding member
* of the envelope is NIL; if these header lines are present but
* empty the corresponding member of the envelope is the empty
