Problem: infradead.org corrupts email subjects by changing:

I found an old thread on mailman-users which appears to be claiming
that it's just standard folding as described in RFC2822 §2.2.3.

https://mail.python.org/pipermail/mailman-users/2007-May/057119.html

2.2.3. Long Header Fields

   Each header field is logically a single line of characters comprising
   the field name, the colon, and the field body.  For convenience
   however, and to deal with the 998/78 character limitations per line,
   the field body portion of a header field can be split into a multiple
   line representation; this is called "folding".  The general rule is
   that wherever this standard allows for folding white space (not
   simply WSP characters), a CRLF may be inserted before any WSP.  For
   example, the header field:

           Subject: This is a test

   can be represented as:

           Subject: This
            is a test

But this is folding at a *comma*, not at whitespace. The original
subject line was (in a single line):

Subject: [PATCH v2] dt-bindings: mtd: jedec,spi-nor: remove unneeded properties

... and Mailman 'folded' it in the wrong place to:

Subject: [PATCH v2] dt-bindings: mtd: jedec,
 spi-nor: remove unneeded properties

That *isn't* proper folding because it didn't happen at a whitespace.

I do need to upgrade to Mailman 3 at some point; I've been
procrastinating on the basis that it "ain't broke". For the time being
I've just disabled folding in MM2 with a trivial hack:

Yay!!! I should have asked years ago...

Any chance the appending of footers can be stopped as it causes lore
to report duplicates and b4 dmarc attestation to fail?
