I have a question about spam. I have been de-Goolefing my life as much as possible. I've shifted my email from gmail to my personal domain email hosted at HostGator. My domain registrar is Hover. I'm using Thunderbird, in plain text mode, on a Linux box. An email, containing no links, sent to a Yahoo address ended up marked as spam. Any thoughts on why? I've never used my domain to send emails, therefore, I assume, it can't be listed in any spam filters as a spamming domain, right?

@elaterite I wouldn't run it on host gator. Your likely on a ton of black/block lists.

I personally use proton mail. And if you like Thunderbird you can use the proton bridge.

@elaterite to expand upon further. Most cloud or cheap hosting is blocked, because they have been abused for years as cheap and easy spam sources. It's an IP/subnet block so you can't easily get around it

@bhhaskin Even if HostGator is doing DKIM and SPF validation as one commenter suggested? What if I used email originating from my domain registrar, Hover?

@elaterite yep! It's all about the sending server IP address. You can check mxtool box.

@elaterite If your mail server isn't using DMARC authentication, that can result in it getting marked as spam. Is it doing DKIM and SPF validation? All things to research & check.

@zolachrome Thanks so much, I'll check into all of that!
