Hi, we are having problems getting mail delivered from our Zoho Mail account to wowway.com addresses. The error message received on the returned mail is:
Error, ERROR_CODE :554, ERROR_CODE :5.7.1 [P4] Message blocked due to spam content in the message.
Wowway support is blaming zoho mail.....
I can provide the full email headers / message (the message content is only a single line) in a private message.
Thanks!
