People who use default Linux installations (at least RedHat) and DHCP will also get a domain part of "localhost.localdomain". # emacs -q -batch -eval '(princ (concat (system-name) "\n"))' localhost.localdomain # hostname -f sjosefsson-lap So the only "random" part that make Message-Id unique are time. Not good, I think. (XEmacs 21.2 is the only emacsen on my system that report correct hostname.)
