That's a good point though it has evolved to be more of a binary
choice, good or bad.

Spamassassin tries to divine that via various methods, including
optionally such lists, but by default just features of the email
itself such as does it contain "invisible" text (white text on white
background) probably intended to deceive Bayes filters or similar,

Amazed? Maybe I'm more cynical.

Many probably view this as potentially rendering their precious email
pitches undeliverable to many.

Barely on topic but I will continue my prediction that "Spam-II The
Next Generation" will involve sources you have had some legitimate
contact with but now you're being inundated from them and hundreds
like them.

For example I just got a legitimate email from my landline provider
(yeah yeah) that I Must Pay My Bill Today Or Else! Some inspection
revealed it's not due for about 3 weeks...but hey, why not?, email is
just about free, dialing for dollars!, prey on the easily frightened.

I'm just thankful they don't send a message like that hourly tho there
are some vendors I've bought from who do send some sort of pitch
nearly hourly, certainly several times per day, every day.

Yes they're more easily automatically filtered than bad actors but is
one really going to filter out their utility companies? Or how much
work should one do to separate their wheat from their chaff?
