From the Message manual: ,---- | `Message-ID' | This required header will be generated by Message. A unique ID | will be created based on the date, time, user name and system | name. Message will use `system-name' to determine the name of the | system. If this isn't a fully qualified domain name (FQDN), | Message will use `mail-host-address' as the FQDN of the machine. `---- So you don't _need_ to have a FQDN. What are the chances of the first part of the ID being the same? What's the worst that can happen when the ID's of two different messages are the same?
