Big thanks for idea!
I don't really like it, but I have not found anything better...

I made
10025     inet  n       -       n       -       -       smtpd
  -o cleanup_service_name=clup_ar
clup_ar   unix  n       -       n       -       0       cleanup
  -o header_checks=regexp:/etc/postfix/header_checks
in postfix for auto-reply
submission_host = 10.10.10.10:10025
in dovecot
and this really work

Best Regards
Dmitry
