I am considering starting greylisting to combat spam. I provide for a wide range of domains so need to have things flexible. I realize there can be global exclusions to greylisting, say for ebay, Amazon, etc.
However, I seem to find conflicting answers as whether a specific users (or domains) general whitelist/trusted senders for ignoring spam checks does or does not bypass greylisting. IE: If email@example.com
is in my own trusted sender list and when that sender sends is his mail subject to greylisting procedures or not -- is the first mail delayed or does it come right through? I know that "trusted" bypasses spam checking, but unclear about this same list for greylisting.
Appreciate any clarification. Thanks
