Implement postfix email gateway on a CentOS 7 server

This task is to convert our current main outgoing email server, to a fully functional email gateway. To make this happen you need following things in this server.

1. We need a working installation of postfix. Our server already has postfix installed in working condition. We are using postfix because postfix has better inbox delivery rate than PowerMTA. If you can proof PowerMTA is better then we can use that also.

2. You have to install IP rotation script in the server. As an email server administrator, you should know that sending email from a particular IP address has a limit. There are general rate of email sending is 200 email per hour per IP address. You have to create a configuration that after sending N numbers of email host name and default interface IP address will be changed. The IP address will be iterated from server1 to server6.

3. You have to create outgoing email limitations for users. Postfix doesn’t have this feature I guess. You have to take help or install other service like [login to view URL] Each user will access their account using their following SMTP details.

a. HOSTNAME

b. USERNAME

c. PASSWORD

d. PORT

4. If you don’t get success in point 3.

5. You have to implement authentication methods that mentioned in the tutorial at [login to view URL] for higher inbox delivery.

6. Some times if any user sends spam emails to large number of users IP addresses are backlisted or blocked by some spam filtering authority. You need to learn how to remove domain or IP black list removal as well.

7. You have to learn the warmup process and implement in our email servers for better inbox rate deliverability.

8. Mail gateway should have valid SSL certificate installed.

9. At the end of completing all these things, you have to write a good tutorial for using in future.
