Hi Bastiaan, Other data centres have the same challenge as you. Hosting providers have historically had a bad reputation because a spammer can use a stolen or pre-paid card to sign up and start sending emails in less than an hour. If you offer shared hosting, a customer can upload an in-secure script and turn the server into a snow shoe spam relay. The list just goes on. I think it understandable that some mailbox providers choose not to automatically trust unallocated and unassigned IP ranges from hosting providers.
But, I'm wondering if it's actually a problem for you? You're not providing ready to run email servers. If people want to send email then they should know how to set up an Internet email server and get their specific IP address white-listed. Couldn't this be solved with a knowledge base article? Because users will also have to create SPF records etc. if they expect any type of reasonable deliverability. I say this because we're customers of Hetzner. And we run a mail server on a dedicated server in your data centre. When we commissioned that server, one of the steps we took was to get the IP white-listed by Microsoft. The process took under one hour. Now, perhaps if we didn't know what we were doing it might have taken longer. We have had zero deliverability problems with them since then. Probably because we don't relay spam or engage in opt-out marketing etc. Ken. -- Ken O'Driscoll / We Monitor Email t: +353 1 254 9400 | w: www.wemonitoremail.com _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
