If this were me, I'd set up a mailserver on the web machine and send
mail to it instead of using phpmailer to connect directly to a distant
mailserver. The authentication between phpmailer and the local
mailserver should be near instantaneous, and you can let the local
mailserver deal with transferring mails in its own sweet time. I don't
know if there's a mailserver included in XAMPP installations, but if so,
I'd do that. In fact, if you're just sending simple emails, you could
use PHP's built-in mail() function, which will connect directly to the
local mailserver without further configuration.
