Welcome Email not being sent

Hello,

No welcome emails are being sent upon user activation.  All other emails seem to be sending no problem.  I haven’t had any welcome emails since configuring the email server and didn’t know users were supposed to get them until I read other posts.

I have tried to resolve the issue 2 ways.

1) I clicked the emails tab and checked to see if there are any welcome emails configured there and there are none.  I tried to create my own but there is no “upon user activation” situation.

2)  I have added this function to functions.php

//send a welcome email when a user account is activated
add_action(‘bp_core_activated_user’,’kleo_welcome_user_notification’,10,3);
function kleo_welcome_user_notification($user_id,$key=false,$user=false) {
if(is_multisite())
return ;// we don’t need it for multisite
//send the welcome mail to user
//welcome message
$welcome_email = __( ‘Dear USER_DISPLAY_NAME,

Your new account is set up.

You can log in with the following information:
Username: USERNAME
LOGINLINK

Thanks!

SITE_NAME’ );
//get user details
$user = get_userdata( $user_id );
//get site name
$site_name = get_bloginfo(‘name’);
//update the details in the welcome email
$welcome_email = str_replace( ‘USER_DISPLAY_NAME’, $user->first_name, $welcome_email );
$welcome_email = str_replace( ‘SITE_NAME’, $site_name, $welcome_email );
$welcome_email = str_replace( ‘USERNAME’, $user->user_login, $welcome_email );
$welcome_email = str_replace( ‘LOGINLINK’, wp_login_url(), $welcome_email );

//from email
$admin_email = get_site_option( ‘admin_email’ );

if ( empty($admin_email) )
$admin_email = ‘support@’ . $_SERVER[‘SERVER_NAME’];

$from_name = $site_name;//from
$message_headers = “From: \”{$from_name}\” \n” . “Content-Type: text/plain; charset=\”” . get_option(‘blog_charset’) . “\”\n”;

//EMAIL SUBJECT
$subject = sprintf(__(‘Welcome to %1$s ‘), $site_name) ;
//SEND THE EMAIL
wp_mail($user->user_email, $subject, $welcome_email, $message_headers);

return true;
}

The above function didn’t result in any welcome emails either.

Does anyone have any other suggestions?
