How to use "mime" in vacation or vacation-seconds

I'm using "Pigeonhole Sieve Interpreter" in dovecot(http://wiki2.dovecot.org/Pigeonhole/Sieve), but there is a problem for me!

I want to use html code in vacation, I find the mime params. But there is no example about it! I only find a example in https://www.rfc-editor.org/rfc/rfc5230 in 4.4, but it is not work! Maybe,I have some mistake？ Who can give some more detail ? Thanks!

Solution 
  • vacation :subject "AutoReply${subjwas}"
         :seconds 10
         :handle "auto-resp" :mime "MIME-Version: 1.0
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding:base64
