Hello, im testing out your service with a free account. this week i was able to verify my domain, setup my MX records and receive emails for 2 days, then it stopped working.
I checked my DNS settings and they are the same, no change was made since we added the zoho MX records.
Im able to send, but incoming emails are nowhere to be found. I dont even get an error message stating that the address is invalid, nothing.
Is there a way to troubleshoot?
