Security Fix has an interesting article on the owner of the domain donotreply.com
When businesses want to communicate with their customers via e-mail, many send messages with a bogus return address, e.g. “somethinghere@donotreply.com.” The practice is meant to communicate to recipients that any replies will go unread.But when those messages are sent to an inactive e-mail address or the recipient ignores the instruction and replies anyway, the missives don’t just disappear into the digital ether.
Instead, they land in Chet Faliszek’s e-mail box.
