And yet, Al, it is fairly regularly done. And yahoo.com addresses are even more common -- a usage that, at least at one time, Yahoo actively encouraged for those who were maintaining stores there. I also see mac.com and gmail.com email addresses on business cards fairly regularly. Now, if people ask me for advice, I tell them that they are better off with their own domains and with associated Whois info that points directly to their businesses (no anonymous or hidden registration stuff). But only a tiny percentage ask me. Assuming one of these professional has decided, even by default, to do that, where is it written that they have problems sufficiently severe that you get to decide that they really are not entitled to reliable email? You should also be aware, in case you are not, that in many parts of the world (and even the US) the choice of ISPs for a residential customer is essentially limited to one. And that ISP, based on how they have interpreted advice from the antispam community, has tried to block outbound SMTP connections that go anywhere but to their servers. john _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
