 * Hi,
 * I’m having problems setting up SMTP.
 * I’ve verified my domain with Mailgun and got my SMTP credentials as explained
   in this article:
    [https://tribulant.com/docs/wordpress-mailing-list-plugin/9810/newsletters-mailgun/](https://tribulant.com/docs/wordpress-mailing-list-plugin/9810/newsletters-mailgun/)
 * I’ve added the information in General Mail Settings:

 * When I tested the settings I got an error:
    [https://snag.gy/fMCsFm.jpg](https://snag.gy/fMCsFm.jpg)
 * I’ve tried this with all 3 port/protocol combinations.
 * I went to the troubleshooting web page mentioned in the error message, but I 
   don’t really understand it:

 * Can you help?
 * Cheers
 * Mark

 * Please see our documentation on the SMTP Connect() failed error message: [https://tribulant.com/docs/wordpress-mailing-list-plugin/11049/smtp-connect-failed/](https://tribulant.com/docs/wordpress-mailing-list-plugin/11049/smtp-connect-failed/)
 * Basically the hosting provider is blocking the outgoing PHP socket connection
   and that’s why. Either the port or the protocol is blocked or outgoing connections
   all together. Can you please contact your hosting provider to allow/unblock for
   you?
 * We have the MailGun API integrated in the Pro version of the plugin and that 
   will work using HTTP connections and will resolve the problem. You’ll be able
   to simply fill in an API key under Newsletters > Configuration for MailGun and
   start sending.
 * Let me know if you managed with it?
