I installed the forum, let's say in http://www.example.com/forum/
I set up the new user registrations to "Administrators".
The admin was registered with firstname.lastname@example.org
, and he didn't receive the email with his login data.
When an user registers also, he doesn't receive the notification email, but other admins who registered with @gmail.com emails or other email domains, they do receive the emails normally.
My question is, could there be a problem when the forum is installed in example.com and the emails must be sent to an <address>@example.com ? Otherwise I don't see the reason why he doesn't receive the emails, maybe an anti-spam filter on the mail server?
Thanks for any help
edit: he has the "user management" permissions, since he can log in in the ACP and access the "user and groups" tab
