Hi Massimo,

It depends on what you mean by visible. If you block incoming 587 traffic
from the WAN with Injoy, that traffic will not reach the LAN. However,
clients running on the LAN can generate traffic and 587 and this traffic
will be visible to anything listening to 587.

This depends on your stunnel config which you have not shown. What are
your stunnel accept and connect settings for the smtps service?
