V9.0.1 Bug - Site Registration - Using - Validate eMail

Validate eMail - Does not work with my - gmail email

Manually - Activate Member - Does send - Membership Approved - email to my - gmail email

Validate eMail - Does work with my - Local Server email address
I receive and validate - OK

I only have one NON local server email account - my gmail email
So I am NOT sure if is just - gmail
Local sever email - vs - Non Local sever email
