How i can hide customer emails from managers?

I do not want my managers contact customers from emails, bypassing me.

They must not see customers Emails.

Make backup of your files BEFORE any changes!

Open file osTicketRoot\include\staff\viewticket.inc.php

line ~67

FIND:

<th>Email:</th>

<td><?php

echo $ticket->getEmail();

if(($related=$ticket->getRelatedTicketsCount())) {

echo sprintf('  <a href="tickets.php?a=search&query=%s" title="Related Tickets">(<b>%d</b>)</a>',

$ticket->getEmail(),$related);

}

?>

</td>

REPLACE BY:

<th>Email:</th>

<td><?php

echo "Helpdesk@MyDomain.com";

//echo $ticket->getEmail();

//if(($related=$ticket->getRelatedTicketsCount())) {

// echo sprintf('  <a href="tickets.php?a=search&query=%s" title="Related Tickets">(<b>%d</b>)</a>',

// $ticket->getEmail(),$related);

//}

?>

</td>

Thank you!
