Receiving email in Parse via Mailgun


So I'm new to Mailgun. I'm trying to use it to receive emails and forward them onto Parse so that I can save the information in them to a Parse database. I have a route set up correctly between Mailgun and Parse. Using the 'Send a sample POST' feature from Mailgun, data is added to my database in Parse. So my route is configured correctly from Mailgun to Parse.


Sending an email to [email protected] gives me a bounced email back, with an 550-Please turn on SMTP Authentication in your mail client error. It also says that it's not permitted to relay 550 through this server without authentication. Seems like it's a problem with Mailgun not correctly configuring the mailserver. Maybe?

Things I've Tried

  • Checking all MX records, CNAME, TXT records - all are set up according to Mailgun's specs
  • Not using a MX record - no change
  • Using a different [email protected], or a catchall forwarder from Mailgun - no change in status

Anyone know what's up? It's a weird error that I can't figure out how to debug. Any tips on debugging this would be highly appreciated.


I think your mail client is not allowing mailgun to post data ,,You can lower down the security parameters in ur mail client settings,allowing less trusted systems to post .
