My problem is this;

I need to send 1500 emails via EE, but my provider only allows 500 emails per 5 min’s.

EE can restrict the number of emails sent at once, but from what I see, I cant set it to send this batch of emails every 5 min’s or so.

Is there something I can do to solve this?

From what I understand, you can solve this in EE by changing the

$DSP->ref_rate = 4;

in system/cp/cp.communicate.php to 400 or somthing.

Is there somthing similar in pmachine that I can change? And where?
