I have Dreamhost hosting ($119 per year) and have for more than a decade.
I have my own domain and use Dreamhost’s mail hosting. It’s used for my daily email. No bulk emailing.
A few months a few emails got bounced back to me, saying the IP of the mail server was on a block list. I mentioned this to Dreamhost support and got a canned reply. I also went to the block list site, as directed in the bounced email message, and complained to them.
However, my emails are STILL being automatically marked as spam. I setup a new Outlook.com address for my wife, for example, and tested it by sending her a message. It was marked instantly as spam. People have told me they missed my mail because it was filtered as spam, and I’m not getting replies to some emails I send – which implies they’re being filtered and therefore missed by their recipients.
What’s going on? How can I avoid this happening? I’ve a feeling the answer is going to be “it’s a fact of life on shared hosting” but surely that isn’t acceptable?
If I fix this by moving my mail hosting elsewhere, will my domain still be marked as being spam because it’s associated with that Dreamhost IP address?
