(In reply to Jeremy Harris from comment #1)
> 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

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

Ok, maybe on outgoing message.
Why "validation error" on incoming message?
Message not signed on sender side.

P.S. Maybe this very low priority bug ... but it happens as once a week only
from one host randomly.
