Invalid IMAP sessions being used?

[Uday Reddy]

The following trace shows an IMAP session created for "save" being used for fetching. Is the validity of IMAP session ensured?

VM OK Fetch completed.
VM UID COPY 39939 "vm"
VM OK Copy completed.
VM NOOP
VM OK NOOP completed.
VM UID FETCH 39935:39935 (RFC822.SIZE)
* 4160 FETCH (RFC822.SIZE 134089 UID 39935)
VM OK Fetch completed.
VM UID FETCH 39935:39935 (BODY.PEEK[])
* 4160 FETCH (UID 39935 BODY[] {134089}
)
VM OK Fetch completed.
VM NOOP
VM OK NOOP completed.
VM UID COPY 39935 "vm"
VM OK Copy completed.

There session created for 'save' is also retrieving the entire message map, which is wasteful.

[Uday Reddy (reddyuday)]

This is ok because FETCH and COPY both use UID commands.

[Uday Reddy (reddyuday)]

The message map is being retrieved to get the message flags, which need to be updated before copying messages.

So, this is needed even though it is not the most efficient way of doing it.
