 FACE=3D"Arial" SIZE=3D3>Hm ... Well, I looked at both. RFC822=
 (whoever came up with this </FONT><FONT FACE=3D"Arial"=
 SIZE=3D3>elegant naming scheme? :)) says that "message-id" is=
 indeed a unique, machine-readable identification for an email.=
 Unfortunately, it says that this tag is *optional*! I have=
 myself noticed, that some messages don't have one. Nothing else=
 in 822 or 1939 (POP3) jumps out at me as having the needed=
 qualities. So, I guess the only option remaining is a=
 combination of name, subject and date, and keeping my fingers=
 crossed that important emails don't arrive too close to each=
 other. ;)</FONT></div>
