As I understand it some MUAs (I believe in the Microsoft camp, which is
not normally a shining beacon of standards compliance or privacy), do
not generate Message-Id because the host part of the ID can leak
security/privacy sensitive information. Instead they rely on their
upstream to produce the header... which means the upstream needs to do
the right thing...
