When addressing the first project, Internet mail sent to receive their e-mail system, you are very quick to point out the need for a published MX record in the public domain in the DNS zone. It is this document that tells all the other mail servers on the planet where route e-mail for your domain.

What say the most is the importance of procurement in both the forward (a record) and reverse (PTR record) right DNS entries for the server which the Send connector. In some cases the same server as the connection received, but it need not be. It is very important that every server that is configured as a connector to send Internet have both forward (record) and reverse (PTR record) registered in DNS, and that these documents are accurate that you entered in the FQDN on the General tab of the Send connector. If this server host to send and receive ports, should the MX record on the same name point. If your organization accepts mail for more than one area, you just point the MX record in every area at the same FQDN. It is not necessary that the MX record to a server in the same DNS domain as the MX record point.

You may be thinking, “Why is it so important that all these names correspond ?”… The reason is that the inputs do not match and the lack of a reverse DNS entry is used by most anti-spam services as a signal that the messages are considered must be used by the host as spam. Some organizations, such as AOL and Comcast go so far as to simply block mail from hosts that do not have a reverse DNS entry. If e-mail to get delivered by your organization, you have all you want to reduce the suspicion of the anti-spam services.

projection (a folder) Text entered in the DNS is no different from the publication of a different address. Only with your hosting provider’s DNS work to publish the name that you configured for your Send connector, as you have if you added your MX record or publish the web address for your domain with the full name and IP address visible. It is the entry or reverse PTR record is a bit difficult. Since you can not publish your own PTR record, you will probably not own the IP block in your organization and your ISP. You just have to work with your ISP to the rear entrance to publish. It is “the action of a joint application, and many large ISPs have this functionality for its customer self-help portals. This approach only works if you have a static IP address and range of your

ISP. If your Internet Service

was a dynamic address, the above approach will not work. Provided that you have to make sure that your e-mail is delivered, you have to make a choice. You can change your Internet service provider to a service with a static IP range and follow the instructions above, or use a smart host. A smart host is simply a different server or servers on the Internet, the “Trust”. This is normally a paid service where they give you a username / password to your mail server uses, regardless of the IP address it to authenticate both. These are servers, which then deliver your messages to their final destination. your ISP often offer this service, so start with them first.
