I am a mailserver-newbie trying to change the default 10MB size limit in courier smtp on my server.

I think I have to create a file
Code:
/etc/courier/sizelimit
I did (in my case it only contains the string "52428800"), but the changes don't get picked up. What am I missing?

In case it helps, here are my versions:
