I got annoyed by my postfix inbox being full of spam. The spamhaus
dnsbl blocklist seems to be utterly useless in the age of mailchimp,
sendgrid etc.

This is my attempt to map their ASNs, and to block all their failover
IP ranges.

I am surprised that you are getting so much spam from these big email
senders (mailgun, sendgrid, etc). They usually have zero tolerance on
spam.
