This is done by the imap client. so yes, your iPad is the one that
handles messages differently and instead of sending messages to the
"Trash" it sends them to "Deleted Messages".
imap clients often regionalise the names of folders. So it is poossible
that the iPad software uses different set of standard folder names.
