           Summary: SUBJ_HAS_UNIQ_ID false positive
           Product: Spamassassin
           Version: 2.61
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Rules (Eval Tests)
        AssignedTo: spamassassin-dev@incubator.apache.org
        ReportedBy: steveb@nebcoinc.com


One of our users received an e-mail that contained the following subject:

 Re: BryanLGH-Fallbrook

This triggered the SUBJ_HAS_UNIQ_ID rule which added enough points (2.677) to
reach the SPAM threshold.  I tracked it down to the following regex in the
check_for_uniq_subject_id() function:

        # 9095IPZK7-095wsvp8715rJgY8-286-28 and similar
        || /\b(\w{7,}-\w{7,}(-\w+)*)\s*$/

I won't pretend to know the original intent of the regex, but based on the
comment above it, I added a number check to the beginning so the regex is now:

        || /\b([0-9]+\w{7,}-\w{7,}(-\w+)*)\s*$/

This prevents it from flagging the subject I reported above.  However, I'm not
sure it's the proper way to fix the problem.  I checked 2.63, and the regex
hasn't changed any since 2.61.  Can this be fixed for 2.64?  

Thanks,
Steve
