Ever since I deployed this on my server https://l1cafe.blog/2018/06/14/defeat-spammers, I have banned quite a few incoming addresses... And it's been barely a year.
So apparently I can make good-looking handwritten notes. Who would’ve known.
I’m helping scientists understand AIDS, cancer, and Zika. I donate my idle computing time so they can take advantage of my CPU and GPU. It costs me a few cents in electricity, and I help scientific efforts that take mankind forward. Care to join me? https://join.worldcommunitygrid.org?recruiterId=1012755
Hey @Tutanota, that’s a great way to avoid spam! Is this system developed in-house? I would love to learn how it works. Do you use Postfix?
