My contacts are getting spam message from a bogus email

This just means that a spammer has gotten hold of your email address and is sending out spam impersonating you. Unfortunately, there is nothing you can do about it. It's not originating from you. Often or usually the "From:" address shows your real name but a patently wrong address. Of course, many recipients just see your name and gloss over the address. Nothing you can do about that either, except to alert your contacts to be skeptical about such messages and to not respond to them or click any links in them. Once you learn to recognize the obvious signs they're pretty easy to recognize. I get similar messages almost every day that purport to be from my family, usually saying something like, "I forgot to send you these pictures" and providing a link to a probably malware site. I just mark them as Spam and move on.
