Re: IPv6 address literals probably aren't SMTP either
In article 5333970a.6070...@direcpath.com you write: On 3/26/2014 10:16 PM, Franck Martin wrote: and user@2001:db8::1.25 with user@192.0.2.1:25. Who had the good idea to use : for IPv6 addresses while this is the separator for the port in IPv4? A few MTA are confused by it. At the network level the IPv6 address is just a big number. No confusion there. At the plaintext level the naked IPv6 address should be wrapped in square brackets. From: http://tools.ietf.org/html/rfc3986#section-3.2.2 It's messier than that. See RFC 5321 section 4.1.3. I have no idea whether anyone has actually implemented IPv6 address literals and if so, how closely they followed the somewhat peculiar spec. R's, John

R's, John I'm not sure why the SMTP RFC defines IPv6-addr so thoroughly and in an incompatible way with the other RFCs. It would make more sense to refer back to another RFC with authoritative definitions. They're completely missing the fun that's happening with Zone Identifiers in RFC6874 and the hacks to support them some have been doing with the IPvFuture definition. I'm not saying John Klensin shouldn't have a say in how the IPv6 address is defined, but I do think it would be best for everyone to work it out in an official place somewhere so that email software isn't doing the complete opposite of everyone else.
