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.
