Exim.conf reverting back to default
Hi,I'm new here

Ok, I'll get straight to the point. I'm managing a server that handle lots of emails every hour using Exim. This creates a very long mail queue whenever mails get refused, timeout or whatever reason that it can't send out. I tried to modify exim.conf and played with the retry configuration to shorten the lifespan of an email.
The default is
* * F,2h,15m; G,16h,1h,1.5; F,4d,8h
I changed it to
* * F,2h,15m;
and added
* refused F,30m,10m;
among few others. Restarted exim. It works fine for a while. But before I know it, those retry configs that I added disappeared from exim.conf and reverted back to
* * F,2h,15m; G,16h,1h,1.5; F,4d,8h
So, what went wrong?

Thanks!
