[PYTHON] Put postfix 2.11 in source with ansible

Task

According to postfix's Official Release Notes

Postfix stable release 2.11.0 is available. This release ends support for Postfix 2.7.

I see

Let's check the default and remi packages.

CentOS 6.4 default package

$ postconf  | grep mail_version
mail_version = 2.6.6

remi

remi

$ yum install postfix --enablerepo=remi

Package         Arch                   Version                         Repository       Size
=========================================================================================================
Updating:
postfix        x86_64                   2:2.6.6-6.el6_5                updates          2.0 M

It's 2.6.6 so install 2.11.0 in source

What you want to do

1. Install dependent packages
2. Since ansible is used, copy the source wget in advance to the server to maintain idempotency.
3. Make the source [Remaining issues: See below]
4. Create a postfix user
5. Place the config file
6. Placement of startup script
7. Start postfix

The remaining challenges

Most of them are finished by doing make and make install after extracting the source, but when make install with postfix, the console asks the installation directory etc. with CUI.

Therefore, if you try to do it with the above ansible, the processing will not proceed endlessly while waiting for input. I want to know what to do in such a case (because it seems to be usable in another case). .. ..

Summary

Since the mail server is not so clustered, for now, I made install on each server, but I want to enjoy it too.
