Exchange 2000, cant send mail to aol users
Posted on 2006-07-10
Hi, all mail that we send from our company is blocked by AOL. I am working to fix this problem but am having a tough time. Hoping someone has had this same issue and can provide some insight. At this point I feel the problem is because when performing a reverse DNS lookup of our IP, it fails. This is why I think we cannot send mail to AOL users. Our system is setup like this. I am going to use fake info but hopefully you can understand:
mail.test.com = x.x.x.30
x.x.x.30 is nat'd to an internal ip that is our spam filter. its then forwarded to our exchange server.
now the exchange server is nat'd to x.x.x.2
I am not too familiar with all of this so my terms maybe used incorrectly and I apologize ahead of time for that. I can provide any additional info that is needed, Thanks
