I thought I had posted earlier about this, but do not see this message anywhere. I'm still seeing,
"Unable to connect SMTP server:smtpout.mail.zoho.com Reason:Authentication failed:554 5.1.8 Sender Address Blocked"
When sending to any address. I've not seen any bounce messages come back, so I'm not sure what I did to trigger this condition.
Can you please unblock me?
Thanks,
Duca
