Receiving that error when I try to send from my site using woocommerce only but using webmail in the cPanel is working fine. Any idea I'm on a shared hosting
The antispam software being used is flagging the email coming from the PHP script as spam. Is that associated with your service or is it coming from the remote server? Either way, it'd need to be investigated with the server flagging your mail as spam to identify what is causing it.
