I am getting the following error message when I try to send mail out to alsmost any domain Final-Recipient: rfc822; [email protected] Action: failed Status: 5.0.0 Diagnostic-Code: X-Postfix; Host or domain name not found. Name service error for name=aol.com type=AAAA: Host found but no data record of requested type Sometimes mail goes out other times it does not. Local mail seems to work fine (menaing as long as the user is on my mail server mail is deleivered). This just started this afternoon. I am not sure where to check or look. This mail server has been up for a couple of years with not a single problem. All inbound mail seems to work fine-it looks like outbound is only affected

outbound mail following again After pulling the files requested I decided to test outbound/inbound mail again and it alll seeems to be working again. My question is how do I determine that it was the ISP in the future as I suspected that to begin with but was not sure
