Hallo Wilfred!

 WvV> But how are you going to find out if that happens in some corner
 WvV> of fidonet.

I cannot.  The best I can do is to put the node back online which is served
'locally' or another point(s) in different parts of the world and then see
where they show up ... or not as the case might be.  When I did this in the
past a number of messages did go missing but it had nothing to do with
MSGID's ... except in one case where there was no MSGID and it didn't go
missing but created a bunch of actual dupes to be spit out of questionable
setups.  That is why I always put a MSGID in my messages.

 WvV> You can hardley check every node in fidonet...

Nor am I planning to.  I am satisfied that if nothing else at least it
found it's way back to BC despite the wrong date(s) and a non-compliant
MSGID that actually contains very useful information beyond just being
unique.

Het leven is goed,
Maurice
