Some other features of the Mail server

A configured mail server should have other features other than basic functionality:

* Anti-spam capability. Check connections or content to block certain connections and letters that are considered undesirable.

* Anti-virus capability. Block attachments with a virus

* DELIVERY WARNING. When a message in a certain period of time has not been sent away (such as 5 hours), first to the sender warning, rather than wait until the final failure, a few days later know that the letter was not delivered.

* Get a report of failure immediately. Can experiment: For example a letter sends two user user1@aaabc.com;user_none@yahoo.com.cn

See if the failure can be immediately obtained.

* Queue priority. For example, for the rebound letter, automatic response and other letters to give a lower than the limited level of delivery.

* Support SSL/TLS Transceiver. Very useful, especially for cross-border Dispatch.

* Support multiple, that is, an SMTP outgoing connection should be able to send to multiple recipients if they are in a domain. Otherwise the efficiency is too low

* SMART ROUTING. The sender can specify all messages sent to todomain.com to go first 1.2.3.4, if there is no pass, then go the original path is very useful. When there is a dedicated line, you must have this feature in order to expedite the sending of todomain.com messages.

* Edge to delete function. If not, a slow-speed connection in a foreign user, his mailbox has 100 letters, he received 98 times the network broke, it is very troublesome.

* Transceiver monitoring tap function. You can set all messages sent from A to B anonymously forward one to C

* Map user function, all sent to a letter, automatically changed address for A1, MAP domain function, the same for the domain.

* User Mailbox limit

* Number of users to send a quantity limit. Sometimes the user's machine makes a virus, and the user sends thousands of normal messages in a validated manner. To stop this behavior.

* Local Users (selectively) need to verify before they can send a piece. For example, the local domain user1@aaa.com issued to user2@aaa.com also need to verify.

* Check the recipient's legality. You can refuse to accept unowned messages.

* Broadcast function. You can set up a broadcast user so that he has the power to send a letter and broadcast it to everyone.

* User message size control. Is QMail's databytes. However, you can set a different size for a particular user, rather than a global variable. please contact the site, timely note your name. Contact Email: edu#chinaz.com (change # to @).
