HI If a DNS has 2 MX record, when exactly the 2nd (higher cost) one will be used ? When the first one do not respond to a SMTP session or when the 1st one does not existe (respond to a ping request )
Basically I'm moving my customer mail to a new ADSL link, and I was wondering if today I ask the DNSMaster to put a new mx record (lower cost) for the new IP link, will; this cause a problem because that new IP address respond (some kind of router / firewall doing Nat) but there is not server yet behind the router. I will install tomorrow the mail server begind that link, but was concerned about the actual NAT Public Address responding JF _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
