Re: [lamps] [Technical Errata Reported] RFC8398 (5418)

[Wei Chuang <[e-mail]>]

Hi all,

I agree with the errata report.  Background is that I've already been
discussing with Dmitry the bug, and suggested he file the errata so we can
make the change.  The bug is in the SmtpUTF8Mailbox OID
<https://www.iana.org/assignments/smi-numbers/smi-numbers.xhtml#smi-numbers-1.3.6.1.5.5.7.8>
in the example <https://tools.ietf.org/html/rfc8398#appendix-B> found in
the Appendix.  I also agree with him that we can update the email address
to be consistent with the earlier example on page 6 in case the original is
confusing.
