Out of curiosity, why does Exim's default behaviour (using a vanilla
config file) accept a message without Date and Message-ID headers and
relay it without adding them? Does adding "control = submission" have
any other, possibly undesirable, effects?
(As I understand RFC2822, these headers are not strictly obligatory,
but Section 3.6.4 that 'Though optional, every message SHOULD have a
"Message-ID:" field.' and the canonical examples in Appendix A all
have Date and Message-ID headers. I think a reasonable definition of
a "sensible message" would include both of these.)
