There are two problems in section 3.6.4. The first is that it states
up front that Message-ID is optional. The second is that the second
paragraph fails to use MUST when defining the field. Put these two
faults together and you can justify putting anything you want in the
Message-ID field or entirely omit it without breaking spec. Doing so is
annoying, obnoxious, and downright unfriendly but it isn't technically
wrong according to the RFC.
