Assumpte: [exim-dev] [Bug 2730] EAI trace information doesn't log domains as U-labels
https://bugs.exim.org/show_bug.cgi?id=2730

--- Comment #4 from John Levine <exim@???> ---
Please see RFC 6531, section 3.7.3.

When an SMTPUTF8-aware SMTP server adds a trace field to a message
that was or will be transmitted with the SMTPUTF8 parameter included
in the MAIL commands, that server SHOULD use the U-label form for
internationalized domain names in the new trace field.

All of the domain names in a Received header should be U-labels in an EAI
message. That would include the EHLO name in the FROM clause and the local
hostname in BY, even though I know that EHLO has to send A-labels.

Like I said, it's not a big deal, but if you want to follow the spec, that's
what it says.
