Who is allowed to send mail as you
v=spf1 include:zoho.com.au ~all
Your SPF record doesn't authorize Google to send mail. Even though FrostSender connects via Gmail, your SPF check will fail — recipients will treat your mail as suspicious.
Cryptographic signature on every send
No DKIM record found on your domain. DKIM cryptographically signs your outgoing mail so receivers can prove it really came from you. Without it, Gmail and Outlook will mark most of your mail as suspicious or send it straight to spam.
What receivers do when SPF or DKIM fail
No DMARC record exists for your domain. DMARC tells receivers what to do with mail that fails SPF or DKIM. Without it, inbox providers default to being more suspicious of your mail — and you have no visibility into spoofing attempts.
Where your inbound mail is delivered
mx.zoho.com.au, mx2.zoho.com.au, mx3.zoho.com.au
Your MX records point to mail servers other than Google's. Because FrostSender connects through Gmail OAuth, Gmail and other inbox providers will treat mail you send as spoofing — outgoing delivery will fail.
