MIME header error

I loaded the recent 0.1b release to give RoundCube a try.  I have to  

say that I'm impressed for such a young project to have gotten so far.

One of the things that I've found in my tests is this:

X-Amavis-Alert: BAD HEADER Improper use of control character (char 0D
hex) in message header 'MIME-Version': MIME-Version: 1.0\r\n

That is an SMTP header that my virus/spam checker inserted when I  

sent a test message to myself. I thought that the info might help
the developers. It looks like an easy enough one line edit to fix
it. Hope it helps.
