In the last 7 days I have received 1442 junk emails to the ‘postmaster’ inbox for my domain – the inbox that holds all the misaddressed mail. In this case, almost all of them were of the ‘Undeliverable Mail’ type.
To put this into perspective, that’s one junk email every 7 minutes, and is roughly a tenfold increase on the amount I received in the previous week.
