Description
Hi
Registration confirmation email triggers the following rspamd symbol:
Symbol: MV_CASE(0.50)
code for this check is:
rspamd_config.MV_CASE = {
callback = function (task)
return task:has_header('Mime-Version', true)
end,
description = 'Mime-Version .vs. MIME-Version',
score = 0.5,
group = 'headers'
}
i.e. (at least AFAIU) it checks whether the exact (i.e. case-sensitive) header name given is 'Mime-Version'.
https://datatracker.ietf.org/doc/html/rfc1521#section-3 states
Messages composed in accordance with this document MUST include such a header field, with the following verbatim text: MIME-Version: 1.0
i.e. the case of 'MIME' needs to be all uppercase.

this has been fixed by https://github.com/mikel/mail/pull/1503 but it isn't released in any version yet. Anyway, it's something that should be discussed there rather than here.
