--- Comment #1 from Jeremy Harris <jgh146exb@???> ---
The DKIM signing implementation supports a maximum body line length of 16kB.

MTAs in general should handle lines up to 1000 characters (per RFC 5321
section 4.5.3.1.6.):

The maximum total length of a text line including the <CRLF> is 1000
octets (not counting the leading dot duplicated for transparency).

I don't think it's really a bug that one with over 16,000 cannot be
DKIM-signed.
Possibly an enhancement-request, but I've not looked into the coding complexity
and that could make it too dangerous.
