How do I send my email certificate to someone else so that they can encrypt emails they send to me?

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
After this they can then decide to encrypt each email that is sent to you by setting the 'Security Options'.

Why can I not encrypt an email using my email certificate and send it to someone else?

You can only encrypt emails to someone else using their email certificate (public key).
And, to do this their certificate must be stored in your address book.

Why can some people reply to my digitally signed emails and some not?

The ones that can reply will already have your certificate (public key) stored in their address book.
