Can't send mail with attachements from wordpress

Frustrating!

There are a few common reasons why you might not be able to send mail with attachments from WordPress. Let's troubleshoot together:

1. Check your WordPress configuration:
   • Make sure you have the wp_mail function enabled in your WordPress configuration file (wp-config.php). You can do this by adding the following line: define('WP_USE_THEMES', false);
   • Verify that your WordPress installation is configured to use a mail transport agent (MTA) or a mail server. You can do this by checking the wp_mail function in your WordPress code.
2. Check your PHP configuration:
   • Ensure that your PHP installation is configured to allow file uploads. You can do this by checking the upload_max_filesize and post_max_size settings in your PHP configuration file (php.ini).
   • Verify that your PHP installation is configured to allow sending emails with attachments. You can do this by checking the mail.add_x_header and mail.force_extra_parameters settings in your PHP configuration file (php.ini).
3. Check your WordPress plugin configuration:
   • If you're using a plugin to send mail with attachments, such as wp_mail_smtp or SwiftMailer, ensure that it's configured correctly.
   • Check the plugin's settings and documentation to ensure that it's set up to send mail with attachments.
4. Check your server configuration:
   • Verify that your server is configured to allow sending emails with attachments. You can do this by checking the server's mail configuration files (e.g., sendmail.cf or postfix.cf).
   • Check the server's logs to see if there are any errors related to sending emails with attachments.
5. Check the attachment file:
   • Ensure that the attachment file is not too large (exceeding the upload_max_filesize or post_max_size settings).
   • Verify that the attachment file is not corrupted or invalid.
6. Check the mail function:
   • Use a debugging tool like wp_debug or Xdebug to inspect the wp_mail function and see if it's throwing any errors.
   • Check the mail function's return value to see if it's successful or not.
