So you're using multiple IP addresses on your main server? What method are you using to do this (OT's IP Secondary Addresses file, IPNetRouter, or one of Vicomsoft's products)? I ask because the current shipping version of QuickDNS Pro doesn't have support for multiple addresses. However, it is obviously working with your current setup. Actually, according to your DNS, all of the above names except ns2 resolve to 206.117.128.36. >Local smtp testing shows no problems finding the mail server but mail that >bounces back looks like so: I've had DNS Expert run a thorough analysis of usconnect.com. It turned up a few interesting errors, but nothing that explains why mail would bounce. What version of QuickDNS Pro are you using? I ask because both your servers failed the spoofing test. [snip] > ----- Transcript of session follows ----- >451 <ek@usconnect.com>... usconnect.com: Name server timeout This line indicates that the problem lies somewhere in the domain name system. However, there's nothing wrong with your zone file that I can see. There is no indication in the delay notification as to why the DNS lookup failed, though I just queried the server in question; it was able to show me your MX record and the address of mail.usconnect.com. In other words, I can't see any reason for the problem, unless it was caused by a transient network failure. ____________________________________________________________________ Chris Buxton Men & Mice cbuxton@menandmice.com http://www.menandmice.com
