  14. Yes, they iterate, but your problem is that on the second and successive
  15. iterations they are case-sensitive.  The patch is simple; in the alias
  16. lookup subroutine, use newstring to make a copy of the alias being
  17. searched for and downcase it before the search.  As far as I can see,
  18. that bug is present in all versions of vanilla sendmail through 5.67.
  19.  
  20. I seem to recall that it's done correctly in IDA-sendmail.
