As you can see, this function uses a number of the IMAP functions.The new ones are
imap_delete() and imap_expunge(). Note that imap_delete() only marks messages
for deletion.You can mark as many messages as you like.The call to imap_expunge()
actually deletes the messages.
Sending Mail
Finally, we come to sending mail.You can do this in a few ways from this script:The user
can send a new message, reply to, or forward mail. Let’s see how these actions work.
Sending a New Message
The user can choose to send a new message by clicking the New Message button.
Doing so activates the ‘new-message’ action, which executes the following code in
index.php/case 'new-message':
display_new_message_form($_SESSION['auth_user'],
$to, $cc, $subject, $body);
break;
The new message form is just a form for sending mail.You can see what it looks like in
Figure 29.8.This figure actually shows a mail reply rather than new mail, but the form is
the same.We look at forwarding and replies next.
Figure 29.8
You can reply to the message or forward it on to someone else.
