silly question: how does mail get in the sent folder?

[Jochen Staerk]

Hi,

I know that POP&IMAP are used for fetching mail, and SMTP is used for 
sending mail, what bothers me is the question: what protocol is used for 
moving mail, like from folder A to folder B? I suppose that is still IMAP?

Another thing, how do "sent" folders work? When I send mail, that goes 
to my postfix. I understand there is something called LMTP in postfix 
for local delivery, that hooks up with cyrus. When I send a mail, does 
LMTP inform cyrus that this mail also belongs in my "sent" folder?

I've used UW IMAP before, and there was no such thing as LMTP, was SMTP 
used for this situation, then? How does mail get delivered to cyrus, is 
cyrus listening to a SMTP-port (a LMTP-Port?) for Postfix to connect to, 
does Postfix connect with some special IMAP commands or does postfix 
just place some files in some folders?

How comes theses files can have a different format from that used with 
UW IMAP (standard Unix MBOX), then?

Sorry these questions relate to my basic understanding of IMAP and 
Cyrus, I've read Managing IMAP (and "das Postfix-Buch") but they do not 
really cover these kind of basics. If you know a good book, particularly 
about Cyrus, please let me know.

Grateful for any clarifications,
Jochen
