You've said "cable" twice now, plus once in the subject. Postfix doesn't know what "cable" is. "We" don't know what "cable" is. Do you actually mean to say "dynamic IP address" here? Likewise, when you say "backbone" do you simply mean "static IP address"? This is a technical mailing list. We can't help you if you don't provide technically accurate information. If the backup MX indeed has a dynamic IP address then Wietse's suggestion obviously won't work for you and a different solution is needed. -- Stan
