So now I suppose my follow-up question is what's more likely to keep the big MTAs happier? Delays between individual deliveries or limited concurrency? > The documentation also has a warning concerning per-destination > recipient limit (the concept of destination depends on the recipient > limit).

I know that setting destination recipient limit to anything above one defines a "destination" as a domain, so by setting it to 2 we're saying "wait 1s between every delivery to a Yahoo domain," right? And if every message sent is unique, would that mean there'd be no difference between a setting of 2 and the default of 50 in this case?
