Q：好的 謝謝

Q：該網站做最后的校對后就正式解析域名上線發布了，但配置好“WP Mail SMTP”后發測試郵件時提示如下錯誤：
Send a Test Email
There was a problem while sending the test email.
Misconfigured server certificate.
This means OpenSSL on your server isn\’t able to verify the host certificate.
There are a few reasons why this is happening. It could be that the host certificate is misconfigured, or this server\’s OpenSSL is using an outdated CA bundle.
Recommended next steps:
Verify that the host\’s SSL certificate is valid.
Contact your hosting support, show them the \”full Error Log for debugging\” below and share this link with them.
但同樣的配置方式，在其他虛擬主機上都能正常發郵件，請問這是該虛擬主機關閉了相應的函數所致？比如fsockopen函數，麻煩將該虛擬主機配置為能正常通過SMTP發郵件的環境，謝謝！
