Don't waste your time, they don't care. I've blocked all of the blocks I was aware of for a long time and haven't seen it affect any real mail at all. I would encourage people to block their corporate mail servers except that they don't have any. Mail for digitalocean.com is outsourced to Google. They could save themselves a lot of pain by just blocking port 25 across their entire network, and saying if you want to send mail, send it through a submission server somewhere else, and you can get your VPS port 25 unblocked after you've been a paying customer for three months. Other cloud providers do roughly that and it works pretty well. Some of them even monetize it by referring users to freemium service at Sendgrid. _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
