Mailgun domain not found: example.com - digital-ocean

Question

I am trying to setup emails with my own website. Let's say the domain name is example.com.
The name server in use is digital ocean and I also have a gmail account linked to the same (say using contact#example.com).
While setting up things with mailgun, I used mg.example.com (as they said it would also let me email using the root domain). The verification step is done and I can send email using contact#mg.example.com.
However, trying to use the root domain (contact#example.com) gives the following error:
AnymailRequestsAPIError: Sending a message to me#gmail.com from contact#example.com
ESP API response 404:
{
"message": "Domain not found: example.com"
}
How do I resolve this issue?

Answer 1

I got the same error when I copy-pasted the curl example from Mailgun help page.
My domain was set to EU region, and I had to set the api domain to api.eu.mailgun.net instead of api.mailgun.net.
Boom! Working! :)

Answer 2

I am using the EU region with Mailgun and have run into this problem myself. My implementation is a Node.js application with the mailgun-js NPM package.
EU Region Implementation:
const mailgun = require("mailgun-js");
const API_KEY = "MY_API_KEY"; // Add your API key here
const DOMAIN = "my-domain.example"; // Add your domain here
const mg = mailgun({
apiKey: API_KEY,
domain: DOMAIN,
host: "api.eu.mailgun.net" // -> Add this line for EU region domains
});
const data = {
from: "Support <support#my-domain.example>",
to: "recipient#example.com",
subject: "Hello",
text: "Testing some Mailgun awesomness!"
};
mg.messages().send(data, function(error, body) {
if (error) {
console.log(error);
} else {
console.log(body);
}
});
Further options for the mailgun() constructor can be found here.
Thought I'd share a full answer for anybody that's still confused. Additionally, Mailgun Support was kind enough to supply the following table as a reference guide:

Answer 3

IF:
your domain is an EU domain AND
you're using django-anymail as in Rob's answer above
THEN the ANYMAIL setting (in your Django project settings) should specify the API_URL to be the EU one, example:
ANYMAIL = {
'MAILGUN_API_KEY': '<MAILGUN_API_KEY>',
'MAILGUN_SENDER_DOMAIN': 'example.eu',
'MAILGUN_API_URL': 'https://api.eu.mailgun.net/v3' # this line saved me!
}
Before adding the MAILGUN_API_URL I was getting this error:
AnymailRequestsAPIError: Sending a message to xxx#example.com from noreply#example.eu <noreply#example.eu>
Mailgun API response 404 (NOT FOUND):
{
"message": "Domain not found: mailgun.example.eu"
}

Update 8/22/16:
Anymail has been updated to take a new MAILGUN_SENDER_DOMAIN in settings.py. See version .5+ docs.

Original Answer
You did not post your code for how you're sending your email, but you are probably trying to send using the simple send_mail() function:
from django.core.mail import send_mail
send_mail("Subject", "text body", "contact#abc.example",
["to#example.com"],)
When you use this method, Anymail pulls the domain out of your From address and tries to use this with Mailgun. Since your From address (abc.example) doesn't include the subdomain mg., Mailgun is confused.
Instead, you need to send the email using the EmailMultiAlternatives object and specify the Email Sender Domain like so:
from django.core.mail import EmailMultiAlternatives
msg = EmailMultiAlternatives("Subject", "text body",
"contact#abc.example", ["to#example.com"])
msg.esp_extra = {"sender_domain": "mg.abc.example"}
msg.send()
Don't forget the brackets in your To field, as this needs to be a tuple or list even if you're only sending it to one recipient.
For more information, see Anymail docs on esp_extra.

Struggled for days with correct DNS settings and finally found as #wiktor said, i needed to add "eu" to api endpoint to make it work. Its actually also documented here: https://documentation.mailgun.com/en/latest/api-intro.html#mailgun-regions
Sorry for replying as an answer, dont have enough rep to add comment :(

Answer 6

I had the same problem: 404 error, domain not found.
The cause
The EU region selection for the domain on Mailgun
The solution
Change the region from EU back to the default of US.
Since I had not used the domain at all up to this point, I simply deleted it, re-added it, then changed my TXT, MX and CNAME records (for example, mailgun.org instead of eu.mailgun.org) at the domain registrar (which was GoDaddy in my case).

Answer 7

I found my fix with this change:
ANYMAIL = {
...
'MAILGUN_SENDER_DOMAIN': 'example.com', # Using the sending domain in Mailgun
}
