Receiving Mailer Daemon messages on emails I never sent

[SWFloridaJoy]

In the past 10 days or so, I've been receiving all kinds of returned mail
messages -- some from Mailer Daemon, some from other "supposed" post offices.
Each references an address that I have never sent to. I never open any,
just delete them, but I'm wondering if anyone is having the same troubles?
I've scanned my entire system and found nothing but the usual tracking
cookies, etc. I don't know how to stop them. Any thoughts would be greatly
appreciated -- it's making me nervous!

for use. So don't be nervous and just realize that email isn't secure or
trustworthy because anyone can pretend to be anyone else.

It's probably someone sending messages using your email address. Some
