Email Regex Validation Issue in Signup Process

[moemoequte]

I have encountered an issue with email validation in the signup process when using Casdoor. Specifically, I have set the regex for the email option under 'Account items' in organizations to ^\d+@qq.com$, and I also applied the same regex ^\d+@qq.com$ for the email option under 'Signup items' in applications.

Despite this configuration, during the registration test, emails are still being sent to addresses that do not match this regex pattern. I believe that the regex validation should trigger at the point of sending the email verification, preventing emails from being sent to non-matching addresses. Instead, the current behavior sends the email first and only informs users about the invalid email during the final submission of registration, which is not efficient or user-friendly. This issue needs attention to ensure that emails are not sent to unintended recipients, improving both performance and user experience.
