    I was lightly probing this function's behavoir.

    It handles rfc882 fields:

    date
    subject
    message_id
    to
    from
    reply-to
    sender - will generate using 'from' field if not in
    header
    references
    in-reply-to
    cc

    doesn't handle rfc882 fields:
    return-path
    received
    resent- I think this field may be obsolete
    keywords

    If there are other rfc822 fields or behavoirs for the function, then I can't speak of them as they weren't in my test.
    As it is relevent to what I'm currently doing I may add more about this function from time to time.

    This function will cause a PHP Fatal Error if the text you're passing to it overflows a 16 KB buffer internally (SENDBUFLEN in the source).

    I haven't looked into it in depth yet, but limiting the input text to less than 16,384 characters still produced this in one error case on our servers, but reducing the boundary to 12,000 fixed it.

    Most real-world mail headers are well under 4 KB.

    This function is marked as internal function by the c-client library and should not be used by php directly.

    Please be aware that the result will always contain fields that have not been set in the message. For example reply_to and sender will always be set even if there is no Reply-To and Sender header fields are defined in the message.

    The object you get from imap_rfc822_parse_headers differs from the object you get from imap_headerinfo/imap_header in the following points. You won't get the:
    * flags
    * msgno
    * size
    * Maildate
    * udate
    * fetchfrom
    * fetchsubject

    udate can be simulated with
    $headerobj=imap_rfc822_parse_headers ($header);
    $udate=strtotime($headerobj->date);
