Strange Mailer-daemon message
I've had several mysterious messages from the Mailer Daemon lately, but none as strange as the one I just received:<'username@...'>:
Sorry, I couldn't find any host named yahoo.com'. (#5.1.2)
Sorry, I couldn't find any host named verizon.net'. (#5.1.2)
(I've replaced the username with the generic "username".)
Any idea what this means?
