There are four solutions that have been proposed:
1. Omit the From field entirely
2. Use some invalid domain, e.g. @blah.invalid.
3. Use some invalid IP, e.g. @[] or @[0,0,0,0]
4. Introduce some new syntax, e.g. From: "Mickey Mouse" <>
5. Don't make any change because pseudonymity is enough.
Some systems reject messages that have no valid originator address in the
message header, so if there is no From: there would have to be a Sender:
In addition to that, this kind of checking would also cause them to reject
foo(_at_)blah(_dot_)invalid From: addresses, or those using bogon IP addresses
in
domain literals.
