But I would like the user before entering your account PowerStore send an email to (verify user account) to your mail until the user does not check the link sent to your email will not be able to access your account PowerStore.
this your problem WebAssist
if ($serverName != "") ini_set("SMTP", $serverName);
if ($serverName != "") ini_set("smtp", $serverName);
The SMTP mail server is correct hosting the problem is with programming as it does not send registration confirmation email users.
Another is that when a user registers for the first time what you should do your PowerStore 4 is not to directly access the user profile, if not first I should send a confirmation email with a url for confirmation of new user account, you do not make your PowerStore 4.
