Yes, the new Sieve implementation supports this behavior. This is a 
typical case of the new variables extension to the rescue. The following 
script shows a tested example of how this would be achieved:

--------------------------------------------------------------------

require "variables";
require "vacation";

set "subject" "";
if header :matches "subject" "*" {
   set "subject" "${1}";
}

vacation :subject "Auto-Reply msg: ${subject}" text:
Hello,

I am currently on vacation. I'll be gone for six weeks and during that 
time I am conveniently unreachable.

Cheers,

Stephan Bosch
