Hello together,
i am new :)

Since some time, i get more and more spam.

The only anti-spam tool i use, is grossd.

I think, i get more "trust" than i should:

Is there any way to reduce trust of a sender, recipient or client?


I cannot find any documentation - if you could point me to something?
That would be very nice ;-)
