This axes out literally insane overly restrictive regex-based
Message-ID check and replaces it with clean and simple conditions
specified in RFC 3977.
Old check wasn't compliant with any email or netnews internet
standard I know of, and was causing propagation issues.
Even old RFC 822 (email) and RFC 850 (usenet) specifications
don't have so restrictive specifications.
