Glad to know.

I'll double check, but we never discussed setting up something like
this.

I checked several files and the pattern I see is that *INCOMING* mails
have this boundary set, while locally stored copies of outgoing emails
usually have something like 
fdj2RfSjLxBAspz7
set as boundary.

So yes, somewhere some MTA (probably ours, I'll check with my admin)
must "silently" rewrite the boundary. 

Please keep this bug open for the moment, I'll reassign it to the MTA
if we can verify that later (so that the bug trail does not get lost).

Thanks & Greetings
