Quoth Nate Williams on Thu, 24 July: : That's irrelevant. Most machines which send mail send via a machine : that *DOES* have valid hostnames, and the envelope uses that address. : That's the way email has always worked. Quite so. I had not correctly understood that the 'valid hostname' criterion was being limited to the MAIL FROM: field. I suppose (not having messed with sendmail.cf extensively for quite some time and not being familiar with the practices of those who do this filtering) that the checking can be easily deferred until after suitable extraction of the address have been performed, so that the DNS resolvable part is used.
