Not specifically. And you need to tell us how you plan to unequivocally
identify the user in question via SMTP. The protocol has no sure-fire
authentication mechanism.

Now? As opposed to previously?
But yes. There has been obscure threads on this matter over time. Richard
Letts (sp?) along with others such as myself have discussed strategies for
evenly sharing resources across various characteristics, such as envelope
info, submittor uid, submittor IP address and so on. There are interesting
issues associated with this that make a general tool a dang tricky thing.
