At least in the sense that they are re­al­ly full of peo­ple with bad in­ten­tion­s...

• The red stripe are con­nec­­tions blocked be­­cause the sender is list­ed in spam­­cop.

• The blue stripe is con­nec­­tions blocked be­­cause the sender is in NJABL.

• The dark­­er green stripe is con­nec­­tions that are rate-lim­it­ed be­­cause they look like a DOS or ad­­dress spam (client con­nec­t­ing too quick­­­ly)

The top green line is SMTP con­nec­tion­s.

The thin white stripe is re­al con­nec­tions that we al­low to send email.

Of course when you look at those...

• 42% are spam (yes, the fil­ter is quite ef­­fi­­cien­t).

So, about 1 in 5 con­nec­tion at­tempts ac­tu­al­ly in­tends to send a re­al, good, valid email.

I am amazed this email thinga­ma­jig still work­s.
