mail != files.

In order to deliver the messages, you don't want to look at the headers, you
want to look at the envelope address. The same applies to the return
address; it comes from the envelope, not the headers.

It is perfectly legal to have a message with no To: header and an empty Bcc:
header.

If you must deal with the message as a stream of characters (or a disk
file), I'd recommend using an SMTP-formatted message, where the envelope
addresses are contained in the SMTP MAIL FROM (or SAML/SOML/SEND FROM) and
RCPT TO commands. This is sometimes called batched SMTP. RFC821 (as amended
by RFC1123) is the SMTP specification.
