Email::Sender::Transport::SMTP::Persistent − an SMTP client that stays online
The stock Email::Sender::Transport::SMTP reconnects each time it sends a message. This transport only reconnects when the existing connection fails.
This method sends an SMTP QUIT command and destroys the SMTP client, if on exists and is connected.
