I'm testing my filters on both servers (easy install 7.86 and debs v7.83)
Until now only the first char if is a space is eaten in the first line, I can't remember if I see something more, because I can't write my sieve filters like I do at first, now I use many lines and spaces to read more easily and my first test were more dirty writen. Sorry... I
Even this "ugly" one works.
require "fileinto";
require "reject";
if header :contains "Subject" ["1234567A-B-CZAP"]{discard;stop;}
keep;
I think that was the sample filter from the web that I use before that give me more "errors" :
require ["fileinto","reject"];
