RFC5322.From might contain no DNS domain to begin with.
So a From: field address with no domain name has never been valid for

Well, except http://tools.ietf.org/html/rfc6854

You seem to be saying that that doc counters my assertion.

This is a classic example of the problem with such a generic pointer: it leaves the reader to search through the document to find the essential bit of text. And alas in my case, I failed.

I do not see anything in that doc that makes it valid to have a From field with no domain name.

Sorry for being obscure. 6854 says:

   from = "From:" (mailbox-list / address-list) CRLF

And from 5322:

   address-list    =   (address *("," address)) / obs-addr-list
   mailbox-list    =   (mailbox *("," mailbox)) / obs-mbox-list
   address         =   mailbox / group
   mailbox         =   name-addr / addr-spec
   name-addr       =   [display-name] angle-addr
   angle-addr      =   [CFWS] "<" addr-spec ">" [CFWS] /
                       obs-angle-addr
   group           =   display-name ":" [group-list] ";" [CFWS]
   display-name    =   phrase

Which makes the following legal (from the examples in 6854):

      From: Nightly Monitor Robot:;
