Search Again: Reverse DNS problems From: Larry Newman Date: Saturday, February 7, 2004 Time: 11:37:59 am I have 32 IP addresses (less than a Class C) with a Birch Telecom-provided T1 and haven't been able to run a mail server on it (I currently host e-mail for virutual domains, but I do this on a different T1 at a colocation site). I recently had Birch (T1 provider) add reverse DNS records on their DNS servers to correctly handle the reverse lookups for three systems that I eventually want to handle mail, but I am still unable to send mail from my one mail server (jetson.world2you.net) that I currently have on the Birch T1. When I try to send mail from an account on the server, it tried to send, but quickly rejects with the following message: -------------------------- The original message was received at Sat, 7 Feb 2004 10:11:20 -0600 from host71-250.discord.birch.net [65.16.71.250] ----- The following addresses had permanent fatal errors ----- <newman@world2you.com> (reason: 550 5.1.1 user not known) ----- Transcript of session follows ----- ... while talking to mail.world2you.com.: >>> MAIL From:<larrynewman@globalmegatrends.com> SIZE=392 <<< 550 5.1.1 user not known 554 5.0.0 Service unavailable Reporting-MTA: dns; jetson.world2you.net Received-From-MTA: DNS; host71-250.discord.birch.net Arrival-Date: Sat, 7 Feb 2004 10:11:20 -0600 Final-Recipient: RFC822; newman@world2you.com Action: failed Status: 5.1.1 Diagnostic-Code: SMTP; 550 5.1.1 user not known Last-Attempt-Date: Sat, 7 Feb 2004 10:11:20 -0600 From: Larry Newman <larrynewman@globalmegatrends.com> Date: February 7, 2004 10:19:54 AM CST To: Larry Newman <newman@world2you.com> Subject: test test ------------------------------------------ I'm sure that I just don't understand enough about how to set up my DNS to make this work. I run 2 DNS servers on the Birch T1 using QuickDNS. Anyone willing to check out my setup and recommend a solution? Here's my current configuration. Mail server on 65.16.71.232. This is jetson.world2you.net DNS servers: ns1.world2you.net on 65.16.71.230 and ns2.world2you.net on 65.16.71.234 The virtual domain I'm needing to get working is: globalmegatrends.com Current DNS setup: WORLD2YOU.NET world2you.net NS ns1.world2you.net world2you.net NS ns2.world2you.net www.world2you.net A 65.16.71.230 ftp.world2you.net A 65.16.71.230 ns1.world2you.net A 65.16.71.230 ns2.world2you.net A 65.16.71.234 cf1.world2you.net A 65.16.71.238 xserve1.world2you.net A 65.16.71.234 xserve.world2you.net A 65.16.71.234 jetson.world2you.net A 65.16.71.232 world2you.net MX 10 jetson.world2you.net GLOBALMEGATRENDS.COM globalmegatrends.com NS ns1.world2you.net globalmegatrends.com NS ns2.world2you.net globalmegatrends.com MX 10 jetson.world2you.net globalmegatrends.com A 65.16.71.232 ftp.globalmegatrends.com A 65.16.71.232 mail.globalmegatrends.com A 65.16.71.232 www.globalmegatrends.com A 65.16.71.232 webmail.globalmegatrends.com A 65.16.71.232 *.globalmegatrends.com A 65.16.71.232 Doing a reverse lookup on mail.globalmegatrends.com returns: jetson.world2you.net I just ordered a $99 support phone contact with Men and Mice yesterday (and certainly willing to pay it for a fix), but I'm not sure when I'll hear from them and would like to get this working quickly if possible. Thanks in advance if anyone sees anything I can do to make this work. --Apple-Mail-1--908936099
