Why is there a Postfix?

This is an interesting question: Why?PostfixWhat about it? Is sendmail okay? ! ! Speaking of this, we need to talk about the origins of postfix!

Postfix was developed by Mr. Wietse Zweitze Venema (http://www.porcupine.org/wietse. Early mail servers were all set up using sendmail. They were really the only one. There was no semicolon! However, Dr. Venema thinks that although sendmail is easy to use, it is not safe enough, especially the performance is not ideal. The biggest problem is .... the configuration file sendmail. cf is really hard to understand! For network administrators, setting the file sendmail. cf is not a human task.

To solve these problems, Dr. Venema planned to use his boss's first vacation year at IBM in 1998 to design a software suite that could replace sendmail, the website administrator can provide a mail server software that is faster, safer, and "completely compatible" with sendmail! To improve these problems, this plan is really successful! It is also successfully used within IBM. It can be said that it completely replaces the sendmail email server! After the success of the project, Dr. Venema released the self-developed email server for the first time in 1998 and named it VMailer. However, IBM lawyers found that the name of VMailer is similar to that of other registered trademarks, which may cause problems in the previous example. To avoid this problem, Dr. Venema changed the name to Postfix! To avoid this problem, Dr. Venema changed the name to Postfix! What does this Postfix mean after it is fixed. What does this Postfix mean after it is fixed. I personally think that Mr. Venema's earliest idea was not to create a new Mail server software, but to create a software that is completely compatible with sendmail, mr. Venema thinks that the software he developed should be a lack of improved sendmail, so he called it Postfix! Take it as intended: improved mail server software after sendmail!

Therefore, the concept of Postfix is mainly aimed at a completely novel email server software designed to be completely compatible with sendmail. Because of this idea, Postfix improves the security of sendmail, improves the efficiency of the mail server, and makes the configuration file completely ASCII code, and the set content is what humans understand! Because of this idea, you can easily upgrade sendmail to Postfix! This is the original idea of Dr. Venema! Based on this idea, Postfix sets the file support level externally, which is almost the same as sendmail, SASL's SMTP mail authentication function is also supported! It is based on this idea, so, haha! Hurry up and learn how to set up the Postfix, which is an excellent email server!

We have learned from the above that sendmail is incomplete and Postfix is required. I hope this will help you.
