Okay, that makes sense, and is the behavior I'd expect.  A POP3 account
is just a local folder to which mail is downloaded (POP'd) when mail is
checked.  For an IMAP copy-to-local-folder a download-to-local-folder
and mark-delete seems correct.

Whatever you do to the local/POP mailbox after you download the message
has nothing to do with the server.  That just means you left the
messages on the server when you downloaded them;  it doesn't [and can't]
have any correlation to what you do to the message after you download
it.
