      While sending to imh.rsys4.net Postfix discovered a PIX with smtp
      protocol fixup and worked around it's brokenness:

      # telnet imh.rsys4.net 25
      Trying 12.130.135.43...
      Connected to imh.rsys4.net.
      Escape character is '^]'.

      Yep, imh.rsys4.net is protected by a PIX.
