What are the common errors and warnings related to mail() function in PHP, especially when running in safe mode, and how can they be resolved?

When using the mail() function in PHP, common errors and warnings can occur when running in safe mode. These errors may include restrictions on the sender's email address, limitations on the number of recipients, or issues with the mail server configuration. To resolve these errors, it is recommended to check the PHP configuration settings, ensure that the sender's email address is valid, and verify that the mail server is properly configured. 

// Example of setting additional parameters for the mail() function to bypass safe mode restrictions
$to = 'recipient@example.com';
$subject = 'Test Email';
$message = 'This is a test email';
$headers = 'From: sender@example.com';

// Additional parameters to bypass safe mode restrictions
ini_set('sendmail_from', 'sender@example.com');

// Send email using mail() function with additional parameters
$mail_sent = mail($to, $subject, $message, $headers);
if($mail_sent) {
    echo 'Email sent successfully';
} else {
    echo 'Error sending email';
}
