Kinda.  It won't train a message with the same id twice, but that id is
generated when mail travels through the proxy.  So if you download the same
message (through the proxy) twice, then you'll have two messages identical
apart from the ids.  If you used the web interface to find a message after
you had already trained it, training it again will have no effect (unless
the classification is different, then it'll be fixed).

FWIW, the imap filter does the same thing, except that since mail isn't
downloaded (it's a filter not a proxy) mail does get given a permanent
unique id.

If you wanted to train a message twice and not download it twice, you could
simply duplicate the one sitting in the "Unknown" cache and give it a
different name (fitting the scheme).
