No activation mail received

Hello Warmane, Merry Christmas !

A friend of mine tried to create an account on Warmane, but did not receive any activation mail. He did check his spam folder and everything, so he tried the "Retrieve" option at login. None of the 4 options (password reset, account name retrieval, activation mail & TFA) let the captcha box appear, so the form can't be submitted. As a result, his mail can't be sent again, and he can't validate his account.
Is there something you can do ?

Thanks
E.
