Send an email to firstname.lastname@example.org. You will receive a response from "email@example.com". The response will contain the IP address that connects to AOL.
Please perform this test if you are opening a support request.
Many mail servers, even those with an external IP address, route mail out through a firewall or proxy server. From the perspective of AOL's servers, the firewall or proxy IP address is the one connecting to AOL, not the internal mail server. If you’re unsure whether you’re sending through a firewall or proxy server, the following test will show the path of any mail that leaves your system.
Send an email to an account outside your own domain.
View the full header of the email as received by the external account. You will see a series of lines beginning with the word Received. For example:
Received: from 22.214.171.124 (EHLO mail2.sammy.com) (126.96.36.199) by server.outsideEmailServer.com with SMTP; Sat, 23 Aug 2003 12:43:16 -0700 Received: (from send@localhost) by server2.sammy.com (8.8.5/8.8.5) id MAA14276; Sat, 23 Aug 2003 12:43:19 -0700
In this example 188.8.131.52 is the IP address of the server that connected to the external mail server, even though the mail originated elsewhere. Should you find out that you’ve been connecting through a firewall or proxy server, please run the RDNS and Manual telnet tests again using the IP address of the firewall or proxy connecting to AOL's mail servers.
