When you first receive your email certificate you will need to distribute the 'Public Key' to those people who you want to send encrypted emails to you.
To do this
- send them an email and digitally sign it, this attaches the Public Key certificate to the email.
- They must store your email address with the certificate in their address book.
- After this they can then decide to encrypt each email that is sent to you by setting the 'Security Options'.
