Good, glad to hear it. The following is WRONG and BAD advice from multiple perspectives, but it's my own little opinion and I am sticking with it. :) I am not in any hurry to move my email into IPv6 land. For now I am satisfied to have IPv4-only MX records for my domains. My server is IPv4-only, for that matter. Why? Well, in IPv4 the spam problem, while not solved, is well under control. But when spammers move into IPv6, and they *will* when it is in more widespread use, spam is going to be a huge mess. The tools which work so well in IPv4, namely DNSBL services, won't cope with IPv6. I think the only thing which will work for IPv6 would be a new paradigm of default-deny and whitelisting, rather than the IPv4 way of default-allow and blacklisting. Yes, I do acknowledge the necessity to move toward IPv6, but it's a long way off before there are any significant IPv6-only email sites. Right now if you're unable to do mail on IPv4, you're going to be cut off from large parts of the Internet. I don't want to be a pioneer before then. :) -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
