<CRLF>.<CRLF> is the end of mail data indicator. See RFC 821. <Newline><Newline> is a new line and then another new line. But I am having trouble picking the grammar rule to handle it. If it were under the DATA command, it would just be another empty line. But I can't tell what it is when part of the MAIL command. See RFC 821 and RFC 822 (for the grammar). Jeff
