Thanks. So message-id's are indeed optional and therfore NOT a good 
reason for bouncing a message!

Not really. PMMail's companion newsreader, PMINews (which is only 
available for OS/2 and is no longer developed) and which was written 
by the same people (Southside) does generate Message-IDs - there are 
many well known algorithms for generating such IDs which are very 
likely to be globaly unique.
