PHP's mail function

Just be sure to validate the input. Make sure that your form can't be used to send spam.

Here are a few points

1- Use method="POST" instead of GET in your <form> for sending large data like an email.

2- Do not put actual email addresses inside <option>'s value that will reveal those emails to SPAM email crawlers, just put member's id or the name itself in there:

foreach($list as $member) {
    echo '<option value="'.$member->id.'">'.$member->name.'</option>';
}

then when you receive the data find that member and get its email:

$selectedMember = null;
foreach($list as $member) {
    if( $member->id == $_POST['select'] ) {
         $selectedMember = $member;
    }
}
if( $selectedMember === null ) die( 'invalid member' );

and to send the email:

if(!@mail($selectedMember->email1, $subject, $body,
          "Return-Path: <$replyEmail>\nFrom: $name <$replyEmail>") )
{
    echo 'error';
} else {
    echo 'message sent successfully';
}
