原因

The error message "550 5.2.0 from address is not allowed" generally means that the email server has rejected the message because the "From" address is not permitted to send messages through the server. In this case, the issue occurred with users who had special characters in their email addresses or usernames, as the mail server does not support UTF-8 headers.

ソリューション

To resolve this issue, you can update the user's email addresses or usernames to remove any special characters, ensuring compatibility with the mail server. Alternatively, the SMTP server administrator can review and update the server configurations to allow the use of special characters by enabling UTF-8 support.
