18.7 Legacy Series / S/MIME Certificates with OPNsense
« on: October 22, 2018, 06:08:00 pm »
Hi everybody,
since around half a year I use OPNsense as firewall and VPN endpoint at home. I’m quite happy, as the installation is easy and everything I need is included – and of course it’s free
I also use the System:Trust part of OPNsense as CA for all my devices. As I, of course, trust my own CA, everything works fine.
The only issue I currently have is that I would also like to use the certificated for E-Mail encryption and signing. I’m not sure if I do something wrong, but whatever I try I’m not able to use the generated certificated for mail encryption in outlook. I already searched the web and the forum here, but I wasn’t able to find any helpful information. Does anyone ever tried to create certificates for S/MIME encryption for outlook with OPNsense and can give support or a short tutorial here?
