Parses a string resembling an RFC 822 date. This is meant to be leinent in its parsing of dates. Hence, this will parse a wider range of dates than apr_date_parse_http.<p>
The prominent mailer (or poster, if mailer is unknown) that has been seen in the wild is included for the unknown formats. <pre>
