I ahve tried to install postfix on my server but i wasn't available to put it to work

root@ns3041266:~# service postfix start
* Starting Postfix Mail Transport Agent postfix postfix: Postfix is running with backwards-compatible default settings
postfix: See http://www.postfix.org/COMPATIBILITY_README.html for details
postfix: To disable backwards compatibility use "postconf compatibility_level=2" and "postfix reload"
[ OK ]
root@ns3041266:~# service postfix status
* postfix is not running

I couldn't make the postfix server start

Also tried

Several things here:

• You tell us nothing about your system (version/distro of Linux, etc.)
• Configuring Postfix is *NOT* trivial as a mail server...what tutorials did you follow?
• Did you READ the very clear messages, that tell you point-blank what to check?
• Did you try running the postfix configuration checker?

Most importantly, this seems to tie in with your other thread:

...where your 'friend' is trying to literally steal an entire website from someone else, and email addresses are specifically mentioned. So not only do you want help stealing a website and all the contacts, but now you want help spamming them?

I think i have a bad fame but i wasn't tried to steal or spam websites my job at that moment was to get the emails of the clients of sports business and contact with them in order to offer clients to them.

now i am in a team trying yo develop a OCR to traduce images to text, and their ask me if i can configure a service mail on the server.

Well the server is a ubuntu server 16.04 it has a couple of website hosting inside of him using nginx.

I have been following this tutorial https://www.youtube.com/watch?v=SPu4tW_Zo0Y

Getting instructions from YouTube and posting vague questions here...I think the answer to their questions is "No, I can't configure email on the server."

Sorry, but what you just said makes ZERO sense. Using a program to harvest all the emails and configurations from a website, so you can build ANOTHER website to get those customers **IS STEALING**, period. Saying "Oh, it was my JOB to steal these names/website", doesn't make it anything less than stealing.
What, exactly, does OCR have to do with a mail server???? Nothing...however, it DOES have a lot to do with stealing customers from another website.
Youtube isn't a good place for tutorials. You can find actual tutorials by putting "how to configure postfix on ubuntu" into Google and/or reading the postfix documentation.

Sorry, just not going to help someone who wanted to steal an entire website, and now wants help spamming those people he stole.

I hadn't steal a website in fact the scaript i wrote can only take html text code from a website as wget command can do and after with grep browse the email word in the text i don't have to be a malicious hacker to do that silly script, your are having a panic attack shill down man. If they post the email in their website to contact with them i suppose i can used to contact with them and i wass't doing spam because i was contacting with them in the same subject of their business.

Yes lack of details of configuring postfix is my fault i should reformulate my question.

We are using the server to hosting the git repository and we want to recieve and email when a commit was done, that's why i am trying to configure postfix. I will browse more carefully
