Wrong.

As Dave have told you, if the server says in the PERMANENTFLAGS response 
that it accepts \*, it means that you can create arbitrary flags. Yes, this 
means that you can create a flag named "$Forwarded".

Of course if the PERMANENTFLAGS already contains $Forwarded, you can create 
that flag even when the server does not say that you can create arbitrary 
flags. You can also asume the same when there is no PERMANENTFLAGS 
response, btw.

Hope this helps. It's also described in 
http://tools.ietf.org/html/rfc3501#page-64 . Have you read that? Do you 
understand the textual description of the PERMANENTFLAGS response code?

With kind regards,
Jan
