This is all best summed up by section 5.2.9 of RFC1123, which says: The syntax shown in RFC-821 for the MAIL FROM: command omits the case of an empty path: "MAIL FROM:<>" (see RFC-821 Page 15). An empty reverse path MUST be supported. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de
