Message contains invalid header

[Marten Lehmann]

Hello,

sorry, but I'm not looking for a way to change anything in an email, I 
am looking for a way so that Cyrus doesn't check for such errors and 
simply ignores them.

Even if I would remove the according message ids in new messages, I 
still have to migrate the old mailboxes and IMAP is giving me the same 
error on APPEND. So what should I do with all those existing messages? 
Why does cyrus have a problem with an empty message-id header? Or there 
other cases in which cyrus throws this error (like 8bit in headers)?

Regards
Marten
