A minimal example for sending emails with gmail in go
- Clone repo to
$GOPATH/src/github.com/octohedron - Install dependencies
go get- Set env variables
export [email protected]
export email_password=hunter2
export [email protected]- Build & run program
$ go build && ./gomailer &
Serving email server in port 5555- Test it with curl
$ curl -X POST \
-F '[email protected]' \
-F 'name=example' \
-F 'subject=ExampleSubject' \
-F 'message=HelloWorld' \
http://127.0.0.1:5555/sendemail
sentNow you got the email server working, might need to add an nginx proxy, add your basic nginx configuration, then install and run certbot for SSL support
- Install certbot with
apt-get install python-certbot-nginx - Run certbot with
certbot --nginx
Your new site.conf file should look like this
server {
server_name email.example.com;
location / {
proxy_pass http://127.0.0.1:5555;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/email.example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/email.example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = email.example.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
server_name email.example.com;
return 404; # managed by Certbot
}Reload nginx with service nginx restart
Now you can send emails through gmail, for example, with javascript
var formData = new FormData();
formData.append("name", "example name");
formData.append("email", "example email");
formData.append("subject", "example subject");
formData.append("message", "Hello World");
// make the request, change the server address
fetch("https://email.example.com/sendemail", {
method: "POST",
body: formData
}).then(result => {
result.text().then(result => {
if (result == 'sent') {
alert("Email sent successfully :)")
} else {
alert("There was a problem :)")
}
});
});
