Refinement of the dispatch table - how many hours?

There is such a module [file]13964[/file] There is information in the mail [file]13965[/file] And you can make it so that when you click, a regular format table opens 1. date of dispatch 2. Post 3. Status (read, delivered, sent, error, not delivered) - that is, those statuses that we can receive from the mailer? It is important for the client to simply see the list of mails to which we have already sent and the status of the letter and the list of others to which we are still sending How many hours is this?
