The company has been on Sorbs for 3 years and until how done nothing.
I know a rDNS or smarthost is required.
The company has an exchange server on their server as well as some sub domains. The main page has been outsourced too a webmaster so THAT ip is different then our server.
Telus has customer registration screen that allows you too input information about your IP.
The IP and mac are obviously correct, but they have for hostname the ip as sxxx-xx-xx-xxx and the Domain as ab.hsia.telus.net. He told me to change the domain to get the rDNS working, but my questions is should I just put the IP address as our main domain company.com is now outsourced too a webmaster?
I know I had too change all the VPNs too the IP, because company.com no longer worked after the change.
Please let me know if more information is needed.
