Re: [Evolution] Mails moved to another folder by filter also end up in trash folder

I am mostly guessing what is going on for you here, but this may be
what's happening:

Not all IMAP servers support the MOVE operation (RFC 6851).
In that case, when moving a message evolution has no alternative than
COPYing the message to the new folder and deleting the old one.
It's possible that your IMAP server implements a Trash folder containing
all messages marked for deletion but not expunged yet.

That would explain why moving a message makes a copy appear on Trash.

IMHO the best solution would be to update the IMAP server to support
MOVE, so that COPY+DELETE isn't needed. Do you happen to know which IMAP
server is it?
