Dovecot autoresponder with vmail

Question

I have server with postfix and dovecot. E-Mails are delivered with dovecot. /etc/postfix/master.cf looks like this:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/bin/spamc -e /usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop}

I have address that is not valid.

If someone write email there, I want so send autoresponce there and to forward the email to someone else.

I did forwarding with /etc/postfix/virtual:

vess@trabels.net    vess@trabels.net, ticket@trabels.net

However I don't know how to use autoresponder sieve:

require ["fileinto", "vacation"];

vacation
    # Reply at most once a day to a same sender
    :days 1
    :subject "Out of office reply"
    # List of additional recipient addresses which are included in the auto replying.
    # If a mail's recipient is not the envelope recipient and it's not on this list,
    # no vacation reply is sent for it.
    :addresses []
"
Hello,
I will be out of the office till Monday, 29 January with no access to the e-mail.
Please write to ticket@trabels.net.
";

Using /etc/postfix/virtual somehow will be best, e.g. something like:

vess@trabels.net    vess@trabels.net, ticket@trabels.net, autorespond

Responding to non-existent email addresses is not a good idea, spammers will try random addresses (with fake sender addresses) and these are all answered. — wurtel, Jan 24 '18 at 12:24

Actually, it was very easy as soon as I realized that sieve commands are like functions in programming language, except there are no brackets.

I come up with this:

require ["fileinto", "vacation"];

if header :contains "X-Spam-Flag" "YES" {
    fileinto "Junk";

}elsif address :is "to" "vess@trabels.net" {
    vacation "I will be out of the office till Monday.";

}
