Email Protections

[prune]

I did some test with the KH Rainloop client. I sent mail using a domain (in KH also) with no SPF, and it still appeared in Inbox of rainloop. It wasnt marked as Spam either. Some mailbox dont even accept mail from sending domain without SPF.

But I had both checked under Protections. Pls see attached image. Why is the Virus box checked but greyed?

Rainloop doesnt show the Spam score also. Where do you check it?

Is there a way to check sending result/status of mail you sent similar to Cpanel > roundcube?

Is there a way to add Mailschannel to KH? Is it via postfix?
