An account that: Reverse DNS lookup for your IP address is failing. AOL does require that all connecting Mail Transfer Agents have established reverse DNS. After that message I went to reverse DNS research tool where I entered the IP address of the braoadband provider and the result is: Quote Success! It appears you have Reverse DNS. Please note the following points: * If the sender's domain is the only domain sending mail from a specific IP address, we recommend that the reverse DNS entry (PTR Record) match the domain name (A Record), but we do not require it. * AOL does require that all connecting Mail Transfer Agents have established reverse DNS, regardless of whether it matches the domain. * Reverse DNS must be in the form of a fully-qualified domain name -reverse DNSes containing in-addr.arpa are not acceptable, as these are merely placeholders for a valid PTR record. Reverse DNSes consisting only of IP addresses are also not acceptable, as they do not correctly establish the relationship between domain and IP address. Unquote I do not have an e-mail address with the broadband provider instead continue using the same current address of my ISP when I had only a modem connection. On the web page http://postmaster.info.aol.com/errors/421dnsnr.html it says among others: Quote If you are on a dynamic IP address, please call your ISP and request a static IP address with proper rDNS before attempting to send mail to AOL through that server. Unquote The problem is I have no telephone nor my neighbors for the past 2 months. The telephone company apparently blew-up a connection box and has been so far unable to repair it. Any suggestions how to go about it and where do I put the reverse DNS of my e-mail provider if I ever will get it. In the meantime I am sending mail to @aol via operamail.
