Undelivered Mail question

[Adrian Simpkins]

Hi All,

On the 12th I was checking our 3 mailboxes as part of my daily nosing around routine, and noticed that a number of Undelivered Mail Returned to Sender emails. However, when looking into the email I am unable to work out any details around the originating email / request. The text shows as below. I have checked the additional info tab and it just shows the mailbox address. All these emails seemed to have generated overnight, so I was just trying to work out what email was actually not delivered - any ideas welcome

Many thanks
