Mail isn't being sent

I have been unsuccessful in the email test. I do not get an error, and there isn’t anything in the log files.

I also tried adding an author, and sending the invite, also no email received.

Ghost 3.2.0
mail is setup as direct (from the default install)
https://thepmdude.com
Installed on a Digital Ocean droplet (I followed the instructions on ghost.org for installing on ubuntu 18.04 LTS)
There are no errors reported in the console.

Hello @gander2112

i am facing the same issue, i just create my blog on digital ocean and i am unable to invite authors, did you solve your issue?

You have to setup mail from Direct to SMTP

where i should do this?

Under your ghost installation directory you will get a file called config.production.json

Replace the "mail": {"transport:direct"}, part with following

"mail": {
    "from": "yourname<eg@example.com>",
    "transport": "SMTP",
    "options": {
        "host": "yoursmtphost.com",
        "port": 587,
        "auth": {
            "user": "user@domain.com",
            "pass": "password"
        }
    }
},

Adjust the code block with your smtp credentials then Save & then restart ghost.

Your mail should be working

Thanks
