My feelings on the matter are: I sure hope that there is not an IMAP5! I hope to see the completion of IMAP within my lifetime... :-) Although SELECT with a bogus name is a hack that will workaround this limitation in the IMAP protocol, it is not something that we should document or recommend in any way. An UNSELECT type command is outside of the scope of the base specification. However, an extension to IMAP to add UNSELECT type functionality *is* within the scope of the IMAPEXT working group. I recommend that you bring it up there. I will support a proposal for such an extension. For what it's worth, my preference is to add an argument to CLOSE that supresses the expunge rather than adding Yet Another Command, but it's not a big deal in either case.
