I created a certificate with OpenSSL and following commands:
openssl req -x509 -nodes -days 365 -subj '/C=DE/ST=state/L=city/CN=hostname' -newkey rsa:1024 -keyout mycert.pem -out mycert.pem openssl pkcs12 -export -out mycert.pfx -in mycert.pem -name "My Certificate"
And installed it with my Windows 7 machine. Then I tried to send an encrypted email and I got a message that there is no certificate matching my email address
What am I missing?
Thank you for those insights, Thomas. I added the email address but the message still pops up :-( I also read about a root certificate, do I need such thing?
