Signing mails is not a solution against spam.
Spammers have more processing power available than any anti-spam
measure. Signing would only help against spam if you agree to accept
only mails from certain senders (i.e. signed by certain keys). This is
not much different from plain white listing and thus you won't be able
to get mail from anyone you don't know. And no, the WoT won't help: The
spammers have more nodes at their hands than anyone else and are able to
build up WoTs as they like. Further, the WoT - like any PKI - does only
work in smallish groups.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
