Of course it's true. Most servers will accept any email sent to a valid
domain name, then silently discard all messages that don't have valid
user names, expecting that set to be mostly SPAM. This created a new
problem where the legitimate senders no longer know when their mail
didn't get delivered due to a typo in the address.
