vacation 5.4 From:

[Dilyan Palauzov <Dilyan.Palauzov@xxxxxxxxx>]

Hello,
draft-ietf-sieve-vacation-07 sais:

* 5.4. From
*
*   Unless explicitly overridden with a :from parameter, the From field
*   SHOULD be set to the address of the owner of the Sieve script.

I would suggest here another approach: the From is by default the
(first) address, where the mail was sent. E.g. mails to
root@xxxxxxxxx, mail@xxxxxxxxx, and dilyan.palauzov@xxxxxxxxx go all
to the same mailbox, have the same sieve script (not on a duplica of
the script, but opearate on the same script). However when one writes
a mail To: you, her, CC: mail@xxxxxxxxx, then the autoreply shall be
Fron: mail@xxxxxxxxx (instead From: Your-unknown-uncle@xxxxxxxxx). In
a similar way, when one writes To: him, them, CC: root@xxxxxxxxx, the
autoreply shall come From: root@xxxxxxxxx, even if the same script is
executed.

I suggest we use in 5.4 From something like

*   Unless explicitly overridden with a :from parameter, the From field
*   SHOULD be set to the address of recipient's first mentioned address,
*   whose Sieve script is executes.

Moreover, it shall be stated, that the script is executed once per
incoming mail and mailbox (if it is not clear from somewhereelse): if
a mail is To: mail@xxxxxxxxx, root@xxxxxxxxx , then there shall be one
autoreply generatated, not two (as this is the same mailbox). But I
have no idea how the user will be informed about both addresses.

   Greetings,
