The email arrives correctly when I send it directly to myself, so I
assume the ML is mangling things. Didn't something similar happen to
James recently?

Yeah. Maybe it's only happening with non base64 encoded emails.

yes, is this a new issue with the servers mail setup or did we just not
have so long lines previously ?

the length seems truncated around 1000 and smtp_line_length_limit has a
default of around that. RFC 5321 also doesnt allow longer lines so iam
not sure if bumping that limit up is the correct thing to do (if its that
what truncates it)

Iam not a mail expert, but naively to me this looks like the
sender should use base64 or some other encoding if a long line is
encountered

Thanks

It may be the latter. Commit 461d04d956 by Andreas added new disposition 
entries to this kind of output, which is a good 100 extra characters per 
such line. But many of them were already longer than 1000 before it, so 
i can't say.

Can git send-email be configured for this?

The original mail was sent as 'quoted-printable' with "soft" line breaks
([1], section 6.7 (5)) with the actual "physical" lines in the file
wrapped to 76 characters as per RFC.

The mail that arrived from the list was '7bit', where the line length is
indeed limited to 998 characters ([2], section 2.1.1). So it seems
likely that the code that adds the mailing list footer is responsible.
IMO it should be configured to always add the footer as a separate MIME
part rather than mangling the original message body (if it's possible).

Yes, see --transfer-encoding

I dont see an option in the mailman web interface to change the way the footer
is added. But i would be very happy if someone replies and tells me that
i missed something or any other fix. I imagine FFmpeg is not the first or
only project that hit this issue ...

thx
