   As you say, used by the ISP. 

   This my message comes from my own domain, and only my PMMail is 
accessing its mailboxes. 

   But for my mailboxes at T-Online or GMX, it is them who are setting 
the rules, and I would have to implement them in my PMMail, after 
asking.

   I would need a local ID to differenciate against any other algorithm 
used by any other user within that ISP. 

   As I said, such a mechanism is provided in ZCONNECT, but not RFC. 

   But using the own email address, which has to be unique, as a basis 
for numbering, should be OK in most cases. But a sphere of insecurity is 
left, because of the deficiencies of the Internet architecture itself, 
in my view.
