Why the external cannot receive the “Reset password instructions” mail

Problem to solve

Somehow the external cannot receive the “Reset password instructions” mail.
But our employees can receive the “Reset password instructions” mail.

Steps to reproduce

The external user try to retrieve his password at https://xxx.yyy.com/users/password/new, but he didn’t receive the “Reset password instructions” mail.

But if using an email with the same domain of the GitLab website, and then the email can receive the “Reset password instructions” mail.
