I hear ya.  MSGID is defined as node # and 8-char hex. There is plenty of uniqueness right there. But in the case of a reinstall within 3 years, unless the gate software knows where it left off the last time, the new messages after the reinstall may end up being treated as dupes by other systems?

A random number segment in the 8-char string (even if it was as short as 3 hex chars)  would significantly reduce that headache.

(BTW.. this message also serves as test to see if the Subj from your fido message is inherited in my Reply.)
