Many mail servers, even those with an external IP address, route mail through a firewall or proxy server. From the perspective of AOL's servers, the firewall or proxy IP address is connecting to AOL, not the other mail server. If you are unsure whether you are sending through a firewall or proxy server, the following test will show the path of any mail that leaves your system.
Automatic Process:
Send an email to ipconfirm@postmaster.aol.com. You will receive a response from ipconfirm-response@postmaster.aol.com. The response will contain the IP address that connects to America Online. Manual Process:
- Send an e-mail to an account outside your own domain.
- View the full header of the e-mail as received by the external account. You will see a series of lines beginning with the word Received: For example,
Received: from 123.123.123.123 (EHLO mail2.sammy.com) (123.123.123.123) 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 123.123.123.123 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 have 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.
