Message contains invalid header

no, it is not just at mails from Notes clients. I also get this error on 
messages with correct Message-ID. We cannot simply refuse mails because 
some clients don't implement the standards 100% correctly. Our users 
still need the mails and every mailclient can handle it even with errors.

And even Cyrus does handle it if I'm putting such a message in the 
mailbox and do a reconstruct!

So why is it refused at lmtp time? How can I disable this? It is really 
important for me!
