Unable to send mail via Mailgun over api or smtp

Question

I have setup a new account and not verified my domain. I would like to test and confirm mail-send before proceeding with verification and adding payment information.

I have tried curl using the sandbox method and api key (including smtp). I have also tried to use my domain using the top account mail-address as recipient. But each time the send command (both curl and smtp) I get "Mailgun Magnificent API" response - but no mail is delivered. So far the Mailgun API does not look so Magnificent... I have gone through the documentation multiple times and cannot find what I might be doing wrong..

Any help is much appreciated.

Answer 1

Faced the same issue while sending emails via api by php curl. I solved it by changing API Base URL https://api.mailgun.net/v3/YOUR_DOMAIN_NAME to https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages. It's because their api is not only for sending. Hope this helps.

Answer 2

For anyone else trying to figure out what "Mailgun Magnificent API" means in a Mailgun HTTP 200-OK API response, it occurs when posting to https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/some/api/endpoint when /some/api/endpoint is not a valid Mailgun API endpoint.

There are several ways you could accidentally see this. Say your sender domain is "mg.example.com". All of these will respond with "Mailgun Magnificent API":

• Omitting the API endpoint: https://api.mailgun.net/v3/mg.example.com (as noted in another response)
• Misspelling the endpoint: https://api.mailgun.net/v3/mg.example.com/massages (that should be messages with an e)
• Including a # after your domain: https://api.mailgun.net/v3/mg.example.com #/messages (perhaps you tried to add a # comment to your config file, but your config format doesn't support inline comments?)
• Including an extra path after your domain: https://api.mailgun.net/v3/mg.example.com/myapp/messages (maybe you're using a Mailgun client library and set MAILGUN_DOMAIN_NAME='mg.example.com/myapp'—the /myapp part doesn't belong in your domain name)

Note that you won't see "Mailgun Magnificent API" if YOUR_DOMAIN_NAME is not a valid sending domain you've registered with Mailgun. (In that case, Mailgun instead responds 404-Not Found).
