Seeing emails like the following in your Inbox, especially after being away from the office?

This is an excellent case of “computers are stupid”.

Chances are a newsletter was sent to you from generic@ts02.somewhere.com while you were away from the office.

The auto-responder you set to kindly inform people of your absence didn’t know that it was an automated newsletter message, so it did its job and auto-responded.

Unfortunately, the sending address, generic@ts02.somewhere.com, likely doesn’t exist, or is set up to reject emails to it.

Your mail server of course doesn’t know that, and is stubborn, so the “Message will be retried for 2 more day(s)”.

Just ignore it. You’ll likely get several more of these over the next few days as computers senselessly assault each other with unnecessary and unwanted responses.
