Frequently Asked Questions
Common questions about Mailgun for WordPress
Your web server may not allow outbound HTTP connections. Set Use HTTP API to "No", and fill out the configuration options to SMTP and test again.
Testing the configuration fails when using SMTP
Your web server may not allow outbound SMTP connections on port 465 for secure connections or 587 for unsecured connections. Try changing Use Secure SMTP to "No" or "Yes" depending on your current configuration and testing again. If both fail, try setting Use HTTP API to "Yes" and testing again.
If you have to use SMTP and something is still going horribly wrong, enable debug mode in WordPress and also add the MG_DEBUG_SMTP constant to your wp-config.php, like so:
define( 'MG_DEBUG_SMTP', true );
