Archived-At is from RFC 5064. https://tools.ietf.org/html/rfc5064
The weird "=?UTF-8?B?" is an "Encoded Word", per RFC 2047. Email headers are defined to be 7-bit ASCII (yes, still); 2047 provides a way to encode other characters in email headers. Mind you, it looks like all the actual Archived-At links Topicbox would fit in 7-bit ASCII anyway and it'd be nice if they reserved the Encoded Word for when they needed it, but whatever; email is a mess and this is nice to have. https://tools.ietf.org/html/rfc2047 Anthony > On Oct 23, 2019, at 10:45 , Calvin Morrison <cal...@fastmailteam.com> wrote: > > On Wed, Oct 23, 2019, at 8:03 AM, hiro wrote: >> this is the case on any other mailing lists or only a topicbox-internal >> standard... > > Quite right.
