Why did I receive a delivery failure notification for an unrecognized email user after replying to an email?

Question

I recently responded to an email (reply all) that listed 4 friends as recipients. I then received a delivery notification that my response could not be delivered to a fifth address which I do not recognize. Is there someone monitoring my email or does anyone know the cause of this?

Answer 1

Nothing to worry about. Delivery failure notifications are sent back to the sender if and when the email recipient email address is not valid.

Answer 2

While delivery failure notifications are commonplace, having one extra address which is unrecognizable by you is uncommon. There are several causes for this:

1) The mail server hiccupped and added random junk which caused the delivery failure
2) Your e-mail is being routed through that e-mail address
3) One of your friend's e-mail addresses are being routed there.

Suggestion:
Do a search on the e-mail address and determine who or what company owns it. Also, see if it's a single occurrence or if it happens again.

Answer 3

Delivery notification will ocurr if the recipient has a limit with their email and it is full, as well.
Check your address book and ensure that address never existed.
It could also be a mail server error..if it ocurrs again, contact your mail server and tell them to fix it.

Answer 4

Delivery failure is shown because that email address doesnt exist.... nothing other than that

Answer 5

The main advantage is you get to read at least some of the replies and see who answered - after your question is removed for being in violation Happens to me a lot anyway

It's a default settig of E-mail. So, always it will send u this massage if it can't recognize any address.
