I apologize for not expressing my problem in clear enough terms.

My e-mail server will put sent e-mail to the ~/.Maildir/.Sent 
(which is also a Maildir directory); naturally, the e-mail is 
first written into ~/.Maildir/.Sent/tmp, and then it's moved to 
~/.Maildir/.Sent/new.

After this has happened, I would like Dovecot to run a Sieve 
program that will discover that the e-mail is in the "Sent" 
folder, and mark it as seen.

To explain what I'm imagining with code:

if folder :is "Sent" {
    setflag "\\Seen";
}

So I don't use subaddressing. I always know the target mailbox, 
but it's always "Sent" (this is configured in the MTA).

I guess knowing the name of the mailbox that implicit keep stores 
the message in would solve my problem.

I'm assuming you are referring to this:

https://raw.githubusercontent.com/dovecot/pigeonhole/master/doc/rfc/spec-bosch-sieve-dovecot-environment.txt

And in particular this:

   "vnd.dovecot.default-mailbox"
         The default mailbox that is used by the (implicit) keep 
         action.
         Normally, this will always yield "INBOX", unless this is
         changed in the configuration.

It says that this normally will yield "INBOX". Do you, given my 
explanation above, think that it would yield "Sent" in my case? If 
not, how would I be able to use this?

Thanks a million!
