RE: SMTP addresses in <>

his arguments is "even hotmail does not keep up the standards" and if we ignore them as

It sounds like he's admitting that the RFC is correct, but since Hotmail will accept "malformed" messages, so should everyone else. He basically wants you to adjust your server to be more lax so he doesn't have to adjust his to get in line with the RFC. Depending on your business and how important mail is you may or may not be able to tell him to fix his MTA. Personally, if his mail isn't spam I'd lean more toward the "let it through" side of the argument for the sake of cooperation, though if he followed the standards there wouldn't be a problem to begin with. That may be worth pointing out. -Justin Scott
