@hazlin >is just getting the big corpos to receive your mail.
The way they screw over non-botnet mailing servers is to refuse to accept email unless you setup DMARC, SPF and rDNS (DKIM for now usually is optional), but even then they'll randomly drop emails that certainly aren't spam or arbitrarily blacklist your domain with no legitimate reason given.

What's even worse is spam blacklists, which add domains on entirely arbitrary grounds, some of which even add blacklisted IPs to ROUTING TABLES, leading to hard to debug issues with network connections if such censoring routers are on the routing path, which refuse to remove blocks without payment.


The best workaround is to never to have to email to botnet mail servers, which has worked fine for me so far.


It's more of an email replacement idea, where everything is encrypted and signed by default, transmitted via tor .onions or GNUnet addresses (so excellent deliver-ability, anonymously), so nice things can take place.
