This has been hypothesised but I can't think of a reliable way to test
it. Given that the Gmail server side would need to check messages for
duplicates to detect this, it may not be true.

Are you sure? I deleted and expunged a test message using Evo and the
Gmail web interface removed it from All Mail.

Not sure I understand what you mean by this.

I suspect the [Imap]/Sent folder is used when the user specifies it,
but of course the builtin Sent folder is always there, as you say.

It's worth noting that Gmail's use of labels means that the same
message may appear in multiple IMAP folders. There is still only one
copy of the message. Deleting such a message from one folder simply
removes the corresponding label and doesn't remove the message from
other folders. A bit like filenames on Unix in fact. Is that what you
meant by the above comment regarding [Gmail]/Trash?
