Quoth Jim Shankland on Thu, 24 July: : > I have to warn you that several mail server products of which I'm : > aware actualy verify via getpeername/gethostbyaddr (RARP), and : > will reject your host anyway. : : RARP? Or was that just a belch in mid-sentence :-)? : : Seems like it would be nice for those implementing such a policy to : allow chopping of subdomain prefixes; e.g., if getpeername/gethostbyaddr : return foo.bar.acme.com, and the envelope sender is joebob@acme.com, : then it's OK. Or is that too loose? And multiple names. MAIL FROM: jimbob@client.domain.com will often come from isp.domain.net. And non-Internet paths. What about networks that do not use symbolic host names?
