yes, i got that now. I had not gotten that impression when i read the documentation the first few times and even when i observed the behaviour. Partly because i dont see a good reason why the delay cant be combined with the slow start. Now if this is so i dont see a good way to not create peeks in my mail delivery from my high bandwidth connection to other such places, still dynamically ramp up the delivery volume as volume increases and still not be branded as a spammer (who tend to send email in bursts). when looking at the recipent domains of our site, gmail and hotmail take up a big percentage of our mail volume. Whenever i send with default_destination_rate_delay = 0s, in order to be able to use dynamicly increasing volume, I get these steep peeks as mail delivery is virtually instantanious between hotmail, gmail and our box. With default_destination_rate_delay set to a non-zero value however i cant respond to increased mail volume anymore. Therefor i ask to make both features combineable or create a way to otherwise have dynamic slow delivery (with the option to become faster over time). /andreas
