Hello

My colleague emailed me to say he changed the main cpanel password. Would that mess up the automated emails going out?

You are you talking about the cPanel web hosting admin tool? If yes, then no. change of the password for this tool should not cause the failed sending of e-mails.

Yes the password to login to the cpanel.

Are you able to send an e-mail with the PHP mail-function at all with the following script?

<?php
 
$subject  = "Pipapo";
$content  = "This e-mail if for testing.";
$sender   = ""; // add the e-mail-address of the sender
$receiver = ""; // add the e-mail-address of the receiver
$headers  = "From: " . $sender . "\r\n";
$headers .= "Content-Type: text/plain; charset=UTF-8\r\n";
 
$returnValue = mail($receiver, $subject, $content);
 
if ($returnValue === false) {
echo "E-mail could not be passed to the mail server program.";
} else {
echo "E-mail was passed to the mail server program.";
}
 
?>

Tschö, Auge

Not sure how to do this, is that within the cpanel?
