Is it permissible to abort data transfer before the end of data, say
after you have received all headers, and you know the DKIM sig is bad?
RFC-5321 section 3.3 says:
If the verb is initially accepted and the 354 reply issued, the DATA
command should fail only if the mail transaction was incomplete (for
example, no recipients), if resources were unavailable (including, of
course, the server unexpectedly becoming unavailable), or if the
server determines that the message should be rejected for policy or
other reasons.
Failed DKIM would be a policy reason.
