.invalid is specified in RFC 2606 for exactly that purpose. If you
don't notice that the address is invalid a server very close to you,
probably your SMTP server, will tell you. In contrast, your valid
email address will become the target of many spam emails even if you
manage to block them. It will also be used as the source of spam so
somebody at vex.net may be fooled into believing that they are
receiving a proper email.
