You can relax. What you are experiencing is likely a case of email address spoofing.
Simply put, that is when spammers use your address to make it appear as though it came from you.
Because the spammer is using your address, the failed delivery notifications come back to you when the address it was sent to doesn't exist anymore.
Spammers rarely use the same address for long-all you can do is wait it out. I know it's annoying to have those notices in your inbox.
Spoofing an email address equivalent to me writing a letter and using your home address in the top left corner.
If you don't want to see them in your inbox, create a rule/rules based on the subject line in OE to have the notices sent to your deleted items folder.
That way you can delete them all at one time instead of one by one.
Just in case-click on File when you open OE. Choose Empty Deleted Items Folder, confirm you want to delete.
As a precaution, update and run your virus and malware scanners.
