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.
Actually, it is RFC already: https://tools.ietf.org/html/rfc8580 .
I have two questions:
Will ":fcc" be supported in the future?
I'd say yes, but it is not simple to implement, nor is it high up in our list of priorities.
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.)
I can't think of any means to do that within the Sieve language.
Regards,
Stephan.
