Alright, since this came up , it has prompted me to look at our
Content-MD5 header support again.
Here's what I believe to be true:
- We are the only MUA to have ever implemented the Content-MD5 header.
- Currently we will only output it if you include the -check flag.
- Currently we only calculate it correctly if your CTE is quoted-printable
(we may calculate it correctly for some other content types, but that
is debatable).
- We only VERIFY it for content that is encoded with a CTE of
quoted-printable or base64.
This state of affairs strikes me as ... crazy? Anyway, since we don't
get it right in a lot of cases, this suggests to me that we really
shouldn't implement it at all. If someone wants to keep this support,
please make your case; otherwise I propose it be removed and for the
next release the -check/-nocheck flags are turned into NOPs and removed
some point later.
