Creation of Message-ID

[lst_hoe02]

Hello

as far as i know Postfix does not alter a Message-ID beside when it  
creates a missing one. Is there some way one could find out later in  
the logfile if Postfix has created one? Is it sufficient if the  
Message-ID looks like "<some-long-numbar>@<my-mailrelay-hostname>" or  
is there some other thing to check?

Many Thanks

Andreas
