Muhammed Rafi moved quickly and expertly to fix our ailing Zoho Mail system that was seeing about 30% to 40% of good emails constantly going to the spam folder, even when the email addresses and domains were added to our "Safe" senders and "Trusted" domains list in the spam filter. After his fixes the rate of good emails still going to spam was reduced to around 10%. This, apparently, is due to a different issue (dmarc error) we're now addressing with Zoho.
