Error on send email test

Hi, I’m trying to send email from my site using Node.Js (to recover password and other things), but it’s doesn’t work. I found on Digital Ocean forum that this thing is because “Digital Ocean rules”, that we must to use postfix to send a simple email…

So… I followed this tutorial and, when I did send the email test I received the message: mail: cannot send message: Process exited with a non-zero status . This process is complicated you are complicating the simple things here…

Hi @pointdapescaesportiva,

DigitalOcean denies emails being sent on port 25 as they are most often than not spam. With that being said that’s why you’ll need to use postfix and port 465 for sending out e-mails.

On to the problem itself, the most common issues that occur with the error message you’ve provided are :

Reconfigure Postfix

sudo dpkg-reconfigure postfix

Hostname Differs

hostname in /etc/hostname and the name for in /etc/hosts differed.

If the above doesn’t help, I’ll recommend checking out the mail error log in your /var/log folder for further information on the exact issues that are stoping the e-mails from being sent.
