Hi All,
After moving a site to a new server I am having an email/DNS problem.
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 -----
<example-emailaddress@examplehost.com>
(reason: 550 rejected: cannot route to sender <nobody@la.mylocalnet.com>)
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!
Steve
