Sending emails from VPS

Glombersik

Tested on Ubuntu / Debian 7,8
To send a email from VPS need to install Postfix and mailutils package:

Step 1 — Install packages:
As you are logged into the root you do not need to use the command sudo example:

root: apt-get
user: sudo apt-get

apt-get update && apt-get upgrade
apt-get install postfix
apt-get install mailutils

Step 2 — Configure Postfix

sudo nano /etc/postfix/main.cf

search lines
inet_interfaces = loopback-only
change to:
inet_interfaces = localhost

Step 3 -- Restart postfix and test

sudo service postfix restart
echo "This is the body of the email" | mail -s "This is the subject line" user@example.com

We send a test mail to our post office check to see if he means that everything is OK

Flarum should automatically email test if it works thank

This doesn't cover installing a dkim key, or setting up mail records. Without these extra steps you shouldn't try to use a mail-server in production. Much of your outgoing mail will be either sent to spam, or outright rejected.

Glombersik

you're wrong has just sent a message goes only to the inbox never to spam. I invite you to read the documentation: http://www.postfix.org/documentation.html

Well, if you would like to believe so that's to your peril. You've been warned ?

That would be you.

DKIM is required by most mail systems to properly authenticate. Furthermore, you need to create SPF records:

https://en.wikipedia.org/wiki/Sender_Policy_Framework

You will need to generate a key for DKIM on your server. You will need to transmit the DKIM, & SPF records with your domain hosting company. If you fail to take these required steps, most mail services will flag the mail and not send it to a mailbox.

If you were to setup mail 15-20 years ago, doing what you suggest would suffice, but spam mail is a huge deal for a lot of providers, and in order to take action against it, policies are put in place to auto-drop or spambox mail.

I would suggest you send your test mail to a box generated from this site:

https://www.mail.tester.com

Let us all know what score you receive for your oversimplified setup. I call you out to inform others, and yourself that this is not a good idea to try and setup mail without the proper records and key installed. The last thing you want is to be self-assured, and wind up with a lot of unsatisfied users who are unable to register due to email not going through properly.

cool but is used on my forum on nodebb 3 years and does not go to spam so I do not understand what you mean ...

Glombersik what @webeindustry means is when you do not configure your email dns records properly and for instance do not have SPF records set up that indicate the server is allowed to send e-mail on behalf of the domain it won't be delivered on generally all big email providers including gmail and yahoo (to name a few).

Although sounding stern, @webeindustry actually makes a valid point.

Glombersik Please just stop arguing, @webeindustry is completely right and you are wrong. Most of your mails will certainly be filtered by any modern spam filter.

Instead of setting up a Mail server yourself, I would advise people to use a SMTP service. All of the annoying hassle will be taken care of, and for low amounts of mail they are free (and still very cheap when passing that threshold).

Glombersik

Kakifrucht I showed you how you can send mails from their own VPS. So it is right and what? Do you have something to add to give us your solution. Once it is postfix and mailutils to send emails. If we use forum hosting and domain other than the VPS how Mymy send an email?

Wish this was noob friendly. Installed it all... aaaaandddd. No confirmation email.

You wrote and I quote "Flarum should automatically email test if it works thank".

I assume I do not have to configure a thing and everything will automatically send from Flarum? Errrr, nope.

Help? Please?

Or you can have fully managed email server with IRedMail ;-)
