Okay. So, other than debuging - why do we want it (UPNEXPAND)?

With SMTP's EXPN, I think it is only used for debugging. I don't
think  MUA's use EXPN. The reason that I think that, is that
may MTA's do not allow VRFY or EXPN, they return unimplemented.
I would suspect the same for UPNEXPAND. Many will NOT want
to give out membership lists to spammers. And I do not see
any benifit for UPNEXPAND - other than debugging. And
it would not be used from a CUA, or at least it would not
be reliable from a CUA as it can be turned off at the CS.

If I am correct, I would make a motion to remove UPNEXPAND.
