           Summary: Spamassassin does case-sensitive check to identify
                    Received line, should be case-insensitive, so it does
                    not recognize "received:" with lower-case "R"
           Product: Spamassassin
           Version: 2.61
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: spamassassin
        AssignedTo: spamassassin-dev@incubator.apache.org
        ReportedBy: dave230@burtonsys.com

According to the RFCs, the keywords in an email header (such as "Received:") are
supposed to be case-insensitive.  However, when I configured my mailserver to
add a "received: ..." header (i.e., with a lower-case "R"), spamassassin ignored
those received header lines.  The result was lots of erroneous RCVD_IN_...
triggers, because spamassassin was finding the previous (that is, further down)
Received line.

This is a minor bug, because few mailservers generate header lines with
unconventional capitalization.  But it is, nevertheless, a bug.
