Hi there,

I am running UBUNTU+DirectAdmin+Installatron+CSF Firewall/BSF Monitor via dual-VPS with NVMe SSD in a data center in Siauliai, Lithuania.

I am trying to setup zoho emails to my domain and have successfully verified the domain on zoho with Mail Hosting and MX records, but having issues with SPF and DKIM, as hours have passed and still no verification, even though domain and mx records were verified in under an hour. I found on zoho.com that there might be some latency because of TTL value, as it is currently set to 14400 and they recommend changing it to 300.

What kind of impact does that have on the server and is it recommended?

Also since SPF and DKIM isn't verified is there even point starting setting up DMARC? Zoho says not to do this while SPF and DKIM is not setup correctly.(Check out here under Before publishing DMARC section)
