I have used the Sent Confirmation plugin of Squirrelmail (http://www.squirrelmail.org/plugin_view.php?id=192) in my project. Eventhough it is working fine in normal cases, it fails to reliably show the message under the two scenarios.
1) If the server is down at the moment at which it is sending. This the author have mentioned in the README of the package.
2) If I give an invalid ID, say abc@... (such an user does not exist), and if I click send, the error will be shown saying it is an invalid ID. Then if I click on any other link, like Inbox, drafts etc, or if I refresh the page, it will say that the mail has been sent to abc. Is this a known limitation, or is it something I'm doing wrong ? How to overcome this fault ? Any suggestions ? (I'm using compatability package).
