I'll recycle the dnscache and post my internal DNS records here to make sure I am doing it correctly.
New Primary Zone IMCU.COM imcu.com A 12.145.145.177.176 imcu.com MX mail.imcu.com mail.imcu.com A 10.0.50.4 (((((internal address)))))) www.imcu.com A 12.145.177.176 (((((external address for managed website)))))) board.imcu.com A 10.0.10.21 (((((internal address)))))) Should that be all that I need? I have vpn.imcu.com, ftp.imcu.com but they are programmatically only accessible through the firewall so outside in only. After the recycle of dnscache I should be able to do an nslookup for mail.imcu.com and get the ip 10.0.50.4 just like in my hosts file(Which I have commented out until after this experiment works or fails) Thanks From: Kennedy, Jim [mailto:[email protected]] Posted At: Monday, October 29, 2012 8:18 AM Posted To: [email protected] Conversation: DNS? Subject: RE: DNS? Did you also add an MX record for that domain pointing at mail.imcu.com? Most MTA's will fall back to the A record for the domain, so you could also put up an A record for imcu.com. But I wouldn't count on that. Exchange didn't until 2007 or so. From: [email protected] [mailto:[email protected]] Sent: Sunday, October 28, 2012 1:50 PM To: NT System Admin Issues Subject: DNS? I have added a new Forward lookup zone for IMCU.COM on my local active Directory. I have added an 'a' record for 10.0.50.4 for mail.imcu.com in that zone. I do not resolve the mail to the ip. If I add that record in my hosts file I can browse it easily. What is wrong in my DNS set up?
