http://tools.ietf.org/search/rfc5617 Section 3.3 All messages from this domain are signed with an Author Domain Signature and are discardable, i.e., if a message arrives without a valid Author Domain Signature, the domain encourages the recipient(s) to discard it. 4.2.1. Record Syntax discardable All mail from the domain is signed with an Author Domain Signature. Furthermore, if a message arrives without a valid Author Domain Signature due to modification in transit, submission via a path without access to a signing key, or any other reason, the domain encourages the recipient(s) to discard it. Help me out here John, where exactly is that "silently drop" section? I see the discarding part but the "drop silently" part seems to be a bit silent. Other than the "encourages recipient(s) to discard it" phrase, the document gives no other guidance as to what the receiver might or might not do. > >For all you know the ISP may choose to automatically send a notice to > >the intended recipient indicating that they dropped mail from > >example.com based on the published request from example.com and that > >if the enduser has any questions they should contact > >postmas...@example.com. > > Ooh, "we're sending you this useless notification instead of what might > have been spam".
