As described in bug 30013, some outgoing SMTP services ( such as Gmail ) do not like Koha's current behavior of initiating a new connection for each email sent. If we switch from Email::Sender::Transport::SMTP to Email::Sender::Transport::SMTP::Persistent and store the object for the duration of the message queue processing, this should solve that issue.
