Vacation Fcc

Hi list,

I use Dovecot's Pigeonhole Sieve implementation, and there is one little feature I'm missing: When a vacation message is sent, I'd like to keep a copy of that message in my "sent" mailbox.

There is an RFC draft (draft-ietf-extra-sieve-fcc-09) for this, which adds a ":fcc" argument to vacation, but apparently it's not supported by Pigeonhole.

I have two questions:

Will ":fcc" be supported in the future?

In the meantime (or if supporting ":fcc" is not planned), is it possible to achieve the same result with the existing Sieve extensions? (I can imagine a way to do this at the MTA level by checking the presence of the "Auto-Submitted:" header, but did not test it.)

Thanks,

Gregory
