Maybe a postfix newbie question.
Our linux server is properly set up with an SPF record, and we don't send mass email at the moment.
But, is there a simple way to configure the postfix mail queue, when it recieves a request to send 1000s of emails to send at 1 or 2 a second?

You need to tune
default_destination_concurrency_limit
and, possibly, per-transport concurrency limits, although defaults should work fine.See documentation for details.
