How long does it take to build a web server on postfix?

Question

linux

Good day.
I have a task to build a Mail Server on Postfix at work
. The problem is that I have never done this before.
Approximately how long will it take a beginner in all these anti-spam and configurations to collect all the goodness and quality?

Answer 1

I would say this:
1. set up postfix in a simple way, so that it accepts and sends
1.1 we store users in the mysql database, you can start system users, but it’s better in the database (you need to understand mysql a little)
1.2 be sure to check that the server is not open relay 'eat, otherwise the address will quickly fly into blacklists
1.3 to be sure that all cars on the network are "clean" from viruses, this is important until smtp authorization is configured so that spam does not come from infected cars
2. fasten smtp authorization. This gives protection against spamming from your network and protection against unauthorized mailings under the name of another user
3. turn on antispam (from free amavis, it will pull spamassassin, from paid ones I like to look at drweb)
4. configure tls
5. fasten the web face, if necessary,
get mail to work at stage 1 *. the rest of the steps can be done (even in production, if carefully)
-before implementing each item, study the topic
-explain to the authorities that you need time: a week, two, a month,
I would not advise a beginner to take a ready-made constructor like iRedMail. First, all the same, you need to get an idea of ​​\u200b\u200bhow mail works
on the topic postfix setup, it will be useful to read and remember this material

Answer 2

The initial setup can be done in a couple of days, then gradually finished.
Here's what worked for me during the setup process. For the concept of the essence, it will be enough:

Answer 3

To make everything sensible - it's better to take iRedMail, then you will always have time to adjust it. This can be set up in an hour, and then look according to your needs.
