As a baseline, we get about 2Mill email attempts per month.
I implemented months ago and slowly increased the pause up to
1250 ms. I wanted to avoid any false positives (I have had none) and
found that any further increase in the pause doesn't substantially
increase the amount of rejections.
We hit about 125,000-150,000 rejections due to the pause, per month.
It can be controlled in the access DB as such:
The above two lines provide no pause for localhost or anything on 10/8.
