sieve vacation script exclude based on sender email address

[Harondel J. Sibble]

I thought I'd asked this question a few years ago but can't seem to find any eveidence of that so 
here goes.

I've been looking at the sieve docs and recipes, done a lot of googling but no joy so far.

Using stanard vacation script and that works great, however I want to exclude certain sender 
email addressess from ever receiving a vacation autoresponse, how do I go about adding that to 
my existing vacation recipe.

I suspect my search terminology is what is causing me not to find anything as I typically am using 
exclude and similar search terms.
