Subject: Cannot send email thought server via PHP
I face a problem since I migrate my website on Aliyun plaform.
I developed on my personal web-server a website base on Worpress. This
website need to send email to my customers. I used the PHP function from
Worpress to send email. Unfortunately since I migrate my website on
Aliyun I cannot send email anymore. Is there any restriction on Aliyun
to send email thought your server from PHP function?
Thanks for your answer

Hello,
When you migrate a WordPress website to Alibaba Cloud, it's important to note that there might be restrictions or configurations needed to ensure email functionality works as expected. Alibaba Cloud does not impose direct restrictions on sending emails through PHP functions like wp_mail() used by WordPress; however, the default mail server settings may not be configured for outgoing mail, which could lead to issues with sending emails.
Here are a few steps and recommendations to troubleshoot and resolve your issue:
-
Check Email Service: Ensure that your Alibaba Cloud server has an SMTP server set up or is allowed to send emails. By default, most cloud servers do not come with a pre-configured SMTP service for sending emails.
-
Use SMTP Plugin: Instead of relying on the server's default mail function, consider using a WordPress plugin that supports SMTP for sending emails. Popular choices include WP Mail SMTP, Easy WP SMTP, or Mailgun for WordPress. These plugins allow you to use external SMTP services (like Gmail, SendGrid, or Aliyun Mail Service) for more reliable email delivery.
-
Configure Security Groups: If your server is behind security groups, make sure port 25 (or the alternative SMTP port you're using) is open for outbound traffic if you're using an external SMTP server.
-
Aliyun Mail Service: Consider using Alibaba Cloud's own email service, Aliyun Mail Service (AMS), which provides a professional and stable email solution. You can integrate AMS with your WordPress site via an SMTP plugin.
-
Check Server IP Reputation: Sometimes, the server's IP might be flagged due to previous misuse by others, affecting email deliverability. You can check your IP's reputation using services like MXToolbox.
-
Review PHP Settings: Make sure your PHP settings (
php.ini) allow sending emails and have the correct settings for mail sending (e.g.,sendmail_path). -
Log Analysis: Enable and review PHP and/or web server logs to identify any specific error messages related to failed email sending attempts.
By following these steps, you should be able to diagnose and resolve the issue with sending emails from your WordPress site hosted on Alibaba Cloud.
