I have been reading on how to configure sendmail as a smtps server. I have a personal rule through that I never enter anything into a configuration file unless I understand what it does. While for many aspects of what I've been reading I've been able to look up it's function I've found one that I cannot find any documentation for.
Many tutorials have a line similar to this line in their
DAEMON_OPTIONS(`Family=inet, Name=SMTPS-v4, Port=smtps, Modifiers=Eas)dnl
I would guess based on how this documentation defines
S that the lowercase
s forces TLS to be enabled but not with enough confidence that I am ready to try it.
