[rt-users] Loop prevention between two rt systems

[Wozz]

Hello,

  We just had an incident where our rt system and another groups rt system
  got into a loop with auto-responding.  I may be mistaken, but I thought
  there were mechanisms in place to prevent this, as I'm pretty sure our
  system has interacted with other rt systems in the past without any
  problem.  We're running rt v1.0.4 with qmail as the mailer.  Not sure what
  they're running on the other system.  Any idea what might have caused
  this?  Thanks!
