OK. Will look into this, but I suspect that because there is no header 
section in the message and that either

a) sendmail is treating this as a message with an "http:" header and an 
empty message body, so passes the milter a header split into name/value 
parts, ie. "name=http:" value="//test.com", which doesn't as one
in filterHeader(). I would also suspect such messages do not display
in Thunderbird or Outlook Depress, so I don't see the utility by the 
spammer in this sort of message, so it might be a bug in their code.

b) or sendmail passes the single line as a message body without headers 
and that there is a state transition problem in the milter.

I suspect it is more likely a) rather than b). I will look at it this week.
