Mail server ptr record
Posted on 2007-04-05
i have a mail server in my company, i'm using linux, sendmail and bind i have it installed on the same server. i have 2 domains on the same server x.com and y.com, i have my isp ptr record pointing to mail.x.com and mail.y.com, for some reason i can't send emails from mail.x.com to some domains that check ptr records, but i can with mail.y.com. my question is how do i need to setup my mail exchanger because i think is the order of my ptr records and those servers are pulling the first record, i did some read about it, and it is recommended to have just one ptr record, but how do i setup my 2 email domains over the same server and same ip? please help!!!
