Hey Team,

I'm using Zoho Mail with my own domain, and from some of the recipients I'm receiving following error message:

ERROR CODE :550 - Your message to <xx@xxxx.xx> was classified as SPAM. Please add more
            content, cut down on HTML links, use fewer naughty words etc. Also, ask
            your IT dept to make sure your mailserver has REVERSEDNS, SPF, DKIM, and is
            not on any black lists. Your score: 160

I have this problem with two email address now.
My SPF and DKIM is configured, no links in message, just regular business email. Any suggestion how to solve this?
