[SPAM] Vpopmail & end of headers

We are having some issues with Vpopmail , vdelivermail more precisely  
- in the function is_spam()

There is this code that is charged with finding out when the headers end:

switch(spambuf[k]) {
              /* skip blank spaces and new lines */
              case ' ':
              case '\n':
              case '\t':
              case '\r':
                break;


Basically it assumes that if it finds spaces or \n or \t or \r that  
it's a 'blank' character which means the headers are over and it can  
append the Spamassassin tags.

I think this is a problem because there are messages which have for  
example white spaces(WS) followed by newlines in the header:

         \n

That code assumes that line is the end of the headers, but shouldn't  
the end be a new line that contains only \n ( or \r\n ) ?

Thank you!
