• Applicability

  • Canít get around DNS UDP packet size restrictions with multiple IP addresses per name

    • If connection refused, skip to next name
    • Iff connection timed-out, go to next IP address for same name
  • At ~2 min. TCP timeout per IP address, 45 IP addresses = 90 minutes to timeout

    • If you have a queue runner fired off every 60 minutes, you ultimately wind up with all memory taken up and no mail flow
