This pull request changes the SMTP transport to only ping the server if the last message was sent more than a specified number of seconds ago (instead of pinging the server before every message). By default, it will ping the server if 100 or more seconds since the last message have passed.
This should make sending emails with the SMTP transport more robust with many emails, as SMTP servers will often drop the connection if too many non-mail commands are sent (like pinging the server with NOOP commands).
