during some investigation we found, that there is currently different behavior in logging and writing IPv6 addresses in SMTP.
RFC2821 tells to use a token like [IPv6:3ffe:ffff::1] instead of widly used [3ffe:ffff::1]
Currently following different behaviours are known:
Prefix token "IPv6:" used by
Header Log
Sendmail 8.12 yes yes Sendmail 8.11 no no Current IPv6 patch for postfix no no exim ? ? zmailer ? ? IPv6 patch for qmail ? ? courier-smtp ? ? courier-imap - no
Sure there some on the list who can replace the "?".
BTW: what should be preferred in log?
