Problem with supposedly bounced emails I've never sent.

13. Spam filters

It's useful to send out spam with an actual email addresses in the From field. E.g. if they use their own address, they would get quickly added to block lists.

They're (most likely) not attacking you, it's just a way to try and get their spam delivered instead of rejected.

Unfortunately, there's not a lot for you to do to do other than just delete the junk from the various mail servers that reject the spam.

After a few days they'll get tired of faking email from you and move on to a different address.

I've had it happen to me more than once. After a little while the reject emails disappear.

I've also had it happen to me with phone calls! Spammers will fake Caller ID and make it look like I am the caller. I've gotten a couple of confused calls from people that claim that I had just called them. I had to explain that Caller ID is not secure and that some crook had just faked my phone number to try and get them to answer ... since people are much more likely to "pick up" if caller id shows a number close to theirs (same area code, same prefix).
