  Mail transport job for SMTP.
  Internally, all jobs for a specific transport are queued to use the same
  KIO::Slave. This avoids multiple simultaneous connections to the server,
  which is not always allowed. Also, re-using an already existing connection
  avoids the login overhead and can improve performance.

  Precommands are automatically executed, once per opening a connection to the
  server (not necessarily once per message).
