What task should be done to send email from the server?
I am new at linux configuration. My problem is: I do not what tasks should be done to enable sending email from the server. Normally we use contact form where we use php mail() function. I want when I use this function, I would be able to send email. So, please could you guide me anyone as how to configure or which package should be installed.
Moreover, I tried something reading this link https://www.digitalocean.com/community/questions/php-mail-script-does-not-work and use the following command:
sudo apt-get install sendmail
And then applied this command:
sudo netstat -plutn | grep 25
And find the result:
$ sudo netstat -plutn | grep 25 tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1293/sendmail: MTA:
However, please help what I should do in this circumstance.
Thanks in advance,
