Wanted to get involved in your community and noticed my emails from your systems keep getting sent to spam Might be helpful to set up for future users who might give up setting up an account due to never seeing the email. After further digging it looks like your forum mail server isn't added in the spf record along with appropriate DKIM's. These have both been set up on both your main site and the mailing list. Please could you raise a ticket with the wizards

larian.com. 12944 IN TXT "v=spf1 include:prezlymail.com include:_spf.google.com include:amazonses.com ip4:184.108.40.206 ~all" <--- Suggested
As for DKIM this is outside something i can suggest, also there's no need to have multiple "v=spf1" set up it's irrelevant, they can just be one long list of includes.
