Hi I can’t find anywhere more appropriate that I can post this but your links from emails are currently blocked by mail.com - I suggest you contact them to ask them why they are blocking you. It is saying its a dangerous site that can harm your computer so they clearly are getting wrong info from somewhere. Screenshot attached.
Thanks for the information. Unfortunately, I don’t think there is a lot we can do about it.
The forum URLs don’t show up in any public blacklists, so this must be an internal Mail.com block. And on the warning page, I don’t see any option to submit a false positive.
