Email Cc'd to the user does not necessarily arrive in the Sent folder (it does for Gmail users, but Gmail's "folders" have annoying quirks when used with IMAP). Also, IMAP offers bandwidth efficient cut/paste message composition mechanisms for suitably inter-operable low-bandwidth devices. The client does not need to move all the message data back and forth. > That saves no bandwidth - instead it reverses a single MTA->IMAP > mail flow into IMAP->MTA, at the cost of another protocol. The end-to-end story is bit more complex, because the user may be responding to a large message, by e.g. forwarding a large attachment, ... so the data is already on the IMAP server. > There are smarter ways to do this: teach the IMAP server how talk > authenticated SMTP (it can proxy the user's credentials, just like > the MTA can proxy them with BURL).

Marshall Rose did something like this in the late 80's with the pop server in MH toolkit. That POP server supported a message submission command, so that POP clients did not need a separate SMTP server. I too would have expected a new IMAP extension that would allow the IMAP client to ask the IMAP server to post the message. I don't know why this route was not taken. -- Viktor. P.S.

There is no IMAP client that I'm aware of that can 'save' a message to to the Sent folder. What makes the most sense to me is for the IMAP server to have a 'submission service' that can be used by the client *instead* of defining/using an smtp server directly - then the IMAP server could take care of both sending the message and saving the copy to the Sent folder. -- Best regards, Charles

They all do it, that's how messages end up in the Sent folder, you are confused. -- Viktor. P.S.

On the IMAP server nothing gets saved. But you are right. All the other clients that I know save the message on the server or at least are able to save the message on the server. I never managed to do that with Outlook without fancy macros/rules. > -- > Viktor. > // Steve -- GRATIS f�r alle GMX-Mitglieder: Die maxdome Movie-FLAT!
