Starting from today RealSender offers a new security setting: “limit messages number”.
It lets you define a maximum number of daily emails per sender,
so that any excess quantities will be blocked before going on the internet.
It’s not something new, I had already tested it on 2012.
The setup process for RealSender had already been documented.
I just had to use the last version and update the documentation,
with a few changes to make it work smoothly within RealSender.
