BTW you don't need all that header shit on an email. You need To, Subject, Message, From. For example this is probably enough to test with (obviously with real email addresses), after or before your "records added successfully" line:

mail("me@myhouse","Hello","How are you","From: you@yourhouse");

Edit: since newlines may be necessary, even with one line of headers (from): mail("me@myhouse","Hello","How are you","From: you@yourhouse\r\n");
