Hi friend, Thankyou for your mail. External Setup: External mail server Linux (www.mail.abc.com) If anybody is sending mail to abc.com it will reach the E mail server (mail.abc.com) Internal org Mail server setup : Exchange server and using pop con connector downloading all the mails from external mail server and then it will disrtibute to the mailboxes. Now when I want to send a mail I will be using my exchange server smtp ...and here the domain name is abc.com (internal domain AD) so this server also having private ip (192.168.1.1.) when smtp wants to send mail out it will be using isp ip address (202.X.X.X) and sending the mail. Now the ISP Ip was in the spam list (which ip doesnot have reverse dns)...and Yahoo & Aol or rejecting due to this problem ....... If I will register my IP (isp ip ) with abc.com domain ...this exchange will become a external mail server for the Org .which i dont want to. pls suggest friends ..how to do ?
