What is the postal relay on request?
Mail Relay On request is the configuration of the email server that does not have a continuous Internet connection, also known as a dynamic protocol. E -mail server with constant internet connection has a static internet protocol or IP address. This service uses the SMTP ESMTP profile on port 366. With this setting, all the new post office for the e -mail server is held by the Internet protocol service provider (IP). When the e -mail server connects, the messages received are sent and delivered all new messages.
When there is a dynamic IP address, the IP address changes with each connection. In order to reliably send/receive e-mail messages, a postal relay service is required on request. Mail Relay on request is also known as a ate, proven turn or atrne.
In the E -mail server software, the E -mail administrator defines the rules and logs of mailing. Documentation or user manual may refer to the client at Atrn, take note,Because this is as it is as a client. More download and distribution of messages can be organized to meet your user communities' requirements within this function.
A good illustration of this concept and different between the postal relay on request and a continuous relay is the post office. If you have a postal relay on request, your mail is held at the post office until you request it. Then all the mail that has been addressed to you is delivered, and all the mail you want to send to others in pick up and distribution. Customers with a continuous relay have a courier to come to the door with each mail received and take another item to take each mail item for delivery.
The efficiency of computer resources is used by setting a suitable frequency for this type of service. The postal relay on request provides the best balance to control the needs of users and system resources for the vast majorityEmail users.
For sending and receiving an e-mail, the server is programmed to connect in standard, pre-configured intervals. The e -mail server connects to the IP service provider using a specific port and IP address. The verification process is adhered to; Usually, the replacement of security certificates is and then mail is required. In this scenario, the e -mail server is a client and the IP provider is a server. After receiving mail and sending all outgoing mail, the connection closes and the client e -mail server becomes a primary server and distributes the mail received by the e -mail account of the end users.
6 Costs are lower than the static IP address and the uncomfortable for the end user is minimal.
