well, any client that sent large but slightly differing messages
to different recipients, over slow links.  you could optimize bcc 
handling, for instance, by sending the message to the primary
recipients and the bcc recipients in a single DATA command.

but yes, it seems like the sort of thing that would mostly benefit
spammers.
