问题

回答1:

so you want to check mail() is supporting into client's server?

if(function_exists('mail'))
{

}

But, i'm sure this method is not recommended, the best way to check, send an empty message to your self:

<?php
if(mail($to,$subject,$message) != false)
{
   echo 'You can send email';
}
?>

回答2:

You can only check whether mail is sent or not:

$message = "Line 1\nLine 2\nLine 3";

// Send
if(mail('YOUR_EMAIL_HERE@example.com', 'My Subject', $message)) {
  echo "Sent";
}
else {
  echo "Not Sent";
}

Try below code.

if(mail('TEST_ACCOUNT@gmail.com','test','content') != false)
{
   echo 'You can send email from this server';
}else{
    print_r(error_get_last());
}
