If your software is not listed above, you should consult the guide for Mozilla Thunderbird—most email software works the same way.
If there is a manual for the device or software you are using, you should consult it. Look in the table of contents or in the index for key words like “S/MIME”, “certificate”, “PKCS#12”, “sign”, “signature”, „encrypt“.
(Unfortunately the word “signature“ has two completely different meanings in the email context: It can mean both the footer lines usually containing contact information and the cryptographic signature replacing a handwritten signature.)
