[otrs] Rejecting e-mails from non registered customers

[Stein Erik Berget]

Hi all!
I'm sorry if this question have been asked 2 mill. times before, but I was  
not able to find anything when searching the archive  
(http://www.mail-archive.com/search?l=otrs%40otrs.org&q=mail).

My question goes like this:

I would like all my support customers to be registered. But I still want  
them to be able to initiate a request from the normal e-mail interface. I  
would like to set the X-OTRS-Queue header to 'not-registered' for every  
e-mail where the 'from' header do not contain a valid registered customer  
e-mail adress. By setting the queue header I'm able to create a  
autoresponse to them, saying something like: "please visit http://... to  
get an valid customer account. This e-mail have been rejected'...

Is there some examples on how this can be done? Thanks for your time!
