Yes, but if a ODMR client did that (rejected after telling the server

No, of course not. What language in RFC 2645 leads you to that
None that I can quickly see/read offhand. It wasn't a conclusion.
Perhaps a deny is too much but using a "454 Keep Mail On Server" most
likely won't be tolerated in the same way the POP3 client doesn't have
any control of backend Mail Storage Policies (see RFC1939 section 8).
I agree it would be a loophole to any current mail pickup controls
Also, since server will be driven by reply codes and not the response
text, he is can't be a mind reader. If 45x is deemed wasting the
server's time of repeating sending old mail the ATRN client already
has, I could see a denial of using ATRN for this client:

P: 550 Sorry, Use POP3
