If anyone wants an invalid address, use (e-mail address removed).
Certainly not.
The technical aspect is:
It is a violation of Internet standards, particularly RFC 1036 (Standard
for interchange of USENET messages), and RFC 2822 (Internet Message
Format), to which it refers. The `.invalid' top-level domain (TLD) is
not to be used for e-mail in public (RFC 2606: Reserved Top Level DNS
Names). Bottom line: "A mailbox receives mail." (RFC 2822, 3.4.)
See <
http://www.rfc-editor.org/>.
The social aspect is:
Social thinking, reasonable people manage to handle the spam that they
are receiving (by filters); and fight spammers actively (by complaints,
e.g. to admins of open relays) instead of burdening others (i.e. those
who seek to use e-mail as intended, as an important means of non-public
communication, and mail server administrators, of course) with the
consequences of their own (the spam-receivers') incompetence.
Bottom line: Forging addresses helps spammers.
