No.
I've seen a lot of other invalid hacks, too. The only one I've seen
that's syntactically legal is From: ""@[], which may have syntax going
for it, but I do find it somewhat lacking in charm.
It seems to me they are not valid, as from RFC5322 I get the impression
that a From address at least should contain an "@" and a localpart and a
domainname, and even if localpart and domainname would be allowed to be
empty, there's still the "@" sign...
The localpart can be empty (IMO that's highly inadvisable, but it is legal).
