I checked my email yesterday and there were five emails that were undeliverable. I didn't send them. They went to different email addresses but looked the same (ex: tom1@, tom2@, tom3@, etc.). There was a .txt file that was attached to each one. I didn't open it. I've deleted the emails and scanned my computer with MSE and Malwarebytes. Neither one found any issues.

Most likely that a spammer spoofed your address. Not much you can do in that situation.

The other option would be your email account was hacked. You'd need to check the headers or server logs to verify.

The owner of a company I worked for about 6 years ago sent me pic's of his private parts ( I'm male and don't swing that way ) with a link to more, I replied why did you send me a pic of your d*** his reply was what are you talking about then a day or so later seemed his sister or someone needed money cause she was desperately ill, I copied and pasted the last email because I deleted the first one back to him and that was over a week ago and so far have had no response

How would I go about doing that?

You can check the email headers to see if you can find the IP address and HELO name of the machine sending the message. If you've deleted the mail you won't be able to.

You won't have access to the server logs and I don't think a few bounce messages justify bothering your ISP with.

If you think your account was hacked, or just for the heck of it, log into your account from a known clean machine and change your password to a strong one.

From your description my bet is it was just a spoofed email.

My email password was reset due to unauthorized usage. So I guess my account was hacked.

Sorry to hear that. Surprised you only received a few bounces. We usually see a bunch when the account is compromised. You should scan your machines to make sure they are clean and then use a strong password on the account.
