Hi all, We run an imail server with several hundred virt servers on a shared ip address. These are hosting customers and today there smtp server is: mail.theirdomain.com in most cases. Ficticious Examples: mail.roy.com, mail.orange.com
In my imail admin, I have a host name of arriba1.net I want to prepare for the time when most mail systems require a reverse dns pointer record. Will it be sufficient to set up a reverse pointer record for arriba1.net OR will I ALSO need to ask my hosting customers to change their smtp to something like mail.arriba1.net Today, when sending mail from roy.com to say..hotmail, the ip address in play is their hosting ip address. For example, when sending from arriba.net (not arriba1.net), some systems try to do a look up on 216.147.198.2 which is a shared host header ip address that many sites uses. That ip address is not the arriba1.net ip address. I don't see how i could set up reverse records for each mail domain when they are sharing an ip address. So, the alternative i see is to ask my my customers to change their smtp servers in their mail client to mail.arriba1.net and then put in a host alias of mail.arriba1.net in each of their imail configurations.. Oh, and also change their dns record mx records to reflect mail.arriba1.net. Am I thinking about this in the right way? Thanks for your support.
