  Martin:

  Thanks for the suggestions.  I think the only new perl module
  requirement is Net-CIDR.  I did add this via CPAN (MailScanner won't
  start without it).

  I just tried setting Debug=yes and logging the speed.  I get the
  output that follows this message.  It looks as if it spends the
  greatest amount of time creating attachment dirs for the 30
  messages.  Would you agree that this might be a place to look in the
  code for potential bottlenecks?

  Thanks,
  Mike
