Someone else using my e mail address

[#1]

A spammer is using my email address for their multifarious reasons. Their address is lindbladx@striker.ottawa.on.ca   Anyone know how to stop this?

Incidentally I noticed that one other person has posted a similar comment yesterday. Maybe the bad guys concentrating on Plusnet this week?

Sending emails we could all pretend to be someone we're not. It's down to the receiving email system to sort out the genuine from the false addresses. Inconvenient as it can be you cannot stop it.

Im suffering the same, but the headers appear to show mail originating from my account at plusnet.  Passwords changed as a security measure.

@chesterfield  Where did you get the header record from ? Was it an undeliverable message or did someone reply to the original email as this would contain your email address as a “return to” detail.

@Champnet It was an email sent to me, appearing to be from my own plusnet account.

Header:  (XXXXXXX.plus.com is my plusnet ID, chris000 is not an address I use)

Received: from [102.89.0.204] Is a Mail server somewhere in Nigeria, no surprise there….
Using the same email address for send to & reply to is a common trick used by spammers trying to avoid detection. As you’ve changed your password there’s not a lot more you can do.. 
For info only check here to see if, or how, your email address has been harvested https://haveibeenpwned.com/
