https://emkei.cz is site for sending fake mails. You can put in field "from" whatever you like - and Zoho mail pass  it directly into your inbox - DKIM, SPF, DMARC and DNSBL are activated but no use of that... Is there a way to block these fake mails, in mesage header it says that mail did not pass (mx.zohomail.com; spf=softfail (zohomail.com: transitioning domain) but it comes into inbox anyway....
