Hopefully some kind soul can help as I cannot seem to fix this. --- I am using PHP to send email to the website users at they request (reminders etc). Apache runs as user nobody. Server is la.mylocalnet.com on 12.158.234.68 - DNS is on this server. I am getting bounces from bunch of ISPs with an error header like this ----- The following addresses had permanent fatal errors ----- (reason: 550 rejected: cannot route to sender ) I am assuming that the bounce is happening due to an incorrect reverse DNS - Am I correct? This is what I get if I do an nslookup for reverse on my server: la# nslookup Default Server: localhost.mylocalnet.com Address: 127.0.0.1 > set type=PTR > 12.158.234.68 Server: localhost.mylocalnet.com Address: 127.0.0.1 68.234.158.12.in-addr.arpa name = mylocalnet.com 234.158.12.in-addr.arpa nameserver = la.mylocalnet.com > And if I do alookup from another server on another network: oak:~$ nslookup Default Server: monitor.he.net Address: 216.218.130.50 > set type=PTR > 12.158.234.68 Server: monitor.he.net Address: 216.218.130.50 Non-authoritative answer: 68.234.158.12.in-addr.arpa name = dewnay.com Authoritative answers can be found from: 234.158.12.in-addr.arpa nameserver = ctmsq2ns2.cotennet.com 234.158.12.in-addr.arpa nameserver = ctmsq1ns1.cotennet.com ctmsq1ns1.cotennet.com internet address = 206.169.62.212 > It appears my bandwidth provider is causing the problem with an incorrect reverse entry to "dewnay.com". Again, am I correct? If so, should I just get them to delete the entry and let my DNS do its thing? Any help, ideas or suggestions gratefully received. I have a lot of mail stacking up!
