Undeliverable Email Notifications
 

In the last few days I have been getting a great deal of emails telling me that the email I sent was undeliverable. However, I never sent the email in question. Also I am getting emails supposedly from firewalls like Barracuda saying my emails were blocked - but I never sent them. There are no bogus emails in my Sent folders. Is this just spam of phishing? Anyone else start getting these recently?

Sounds like someone has hijacked your domain. The bad news is there is probably nothing you can do about it. The good news is that they generally move on in a few days.

In the meantime, you can probably set up an e-mail filter to send these bad address responses to your junk mail. I would guess you will find that they are all coming back to a limited number of addresses.

Yes to both. On Jan 1, I clicked on one - not a link inside, but just the email itself in Outlook - I don't use the preview pane btw - and my O/S dumped. Just delete them.
