I was looking for a (current) RFC section that says SMTP servers MUST accept messages sent by the null sender "<>", but almost all I found were references that say notifications MUST be sent as null sender.
That in turn might mean a server must accept such senders, but I'd rather see that written down. I did find one reference though on <http://www.rfc-ignorant.org/policy-dsn.php>: "An empty reverse path MUST be supported." (5.2.9 of RFC1123). It that still valid? Does anybody have a newer reference?
