I have webmin installed on my server, along with virtualmin. While Virtualmin emails are correctly authenticated with configured SPF and DKIM settings.... All of my emails from webmin and/or root are being sent straight to trash because their authentication is as follows:
Authentication-Results: mx26; spf=none smtp.mail=webmin@admin.example.com; dkim=permerror header.i=@admin.example.com
Bit of noob at running email servers. How might I troubleshoot this?
