And the first pre-proxy feature could be for handling mails with a local destination - and I'm thinking specifically about my old feature request for the 'submission_server' feature so that emails sent would automatically have a copy added to the sent folder, so that clients could disable the 'Copy to sent folder' feature and avoid the overhead of uploading the email twice. Maybe even be able to detect somehow (not sure if this is possible to be done reliably) if a client is configured to save a copy to sent folder to prevent duplicates of sent messages - and best would be to be able to detect this and refuse the copy with an informative message to disable the Save to sent feature in the MUA…
This is more about the SMTP submission server, which is already more or less implemented, although without the auto-bcc-feature: http://hg.rename-it.nl/dovecot-2.2-patches/file/9d3dd00ecc31/submission.patc...
