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-3.2.2Two errors, actually… As an RFC-821 address, it should be user@[IP]:port in both cases (user@[192.0.2.1]:25 and user@[2001:db8::1]:25).
indeed, but MTAs are know to accept any kind of non RFC compliant emails and trying to make some sense out of it… :P see http://tools.ietf.org/html/rfc7103 which tries to address some of it in a more deterministic way.
