Since there isn’t a lot of documentation around email setup for Ghost, I’m sharing the steps I took to solve my issue.

1 - Logging Mailgun’s response

First, I decided to log mailgun’s response by editing the core/server/services/mail/GhostMailer.js file. In the handleDirectransportResponse function, I added this snippet at the top to log the response directly to a file.

const fs = require('fs');
fs.writeFile("/var/www/ghost/test.log", JSON.stringify(response), function(err) {
    if(err) {
        return console.log(err);
    }
});

• Note that I’m writing to a file called test.log but you can choose your own. Just remember to allow the “ghost” user to write to that file using chown ghost [filename].

• I then restarted Ghost and reattempted the procedure.

2 - Analyzing the logs

With the logs in the test.log, I could finally start working on a solution. Here are the logs I got:

{"accepted":[],"rejected":[],"pending":[{"domain":"quaero.world","exchange":"••••••••••••••••••","recipients":["contact@quaero.world"],"response":"450 4.7.1 Client host rejected: cannot find your reverse hostname, [159.65.193.143]"}],"errors":[],"envelope":{"from":"noreply@quaero.world","to":["contact@quaero.world"]}}

• In my case, I had a reverse domain lookup issue.

3 - The fix

I’m hosting my blog on a DigitalOcean droplet. It turns out, DigitalOcean will properly set the reverse domain lookup only if your droplet’s name is your domain name. By simply changing my droplet’s name, I was able to set custom email addresses.
