CR or LF will improperly terminate SMTP command

           Summary: CR or LF will improperly terminate SMTP command
           Product: James
           Version: 2.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: SMTPServer
        AssignedTo: james-dev@jakarta.apache.org
        ReportedBy: rohammer@earthlink.net


RFC 2821 section 2.3.7 tells that lines which contain SMTP commands should end
with CRLF, and servers must not recognize any other character sequence as a line
terminator.

In James 2.1.2, james.smptserver.SMTPHandler uses the BufferedReader readLine()
method to read envelope command lines from the input stream.  According to the
JavaDoc, this method terminates a line upon receiving any one of: a line feed
('\n'); a carriage return ('\r'); or a carriage return followed immediately by a
linefeed.  I have confirmed this with tests: James accepts either a line feed or
carriage return alone as a line terminator for envelope command lines.
