Email sent to DigitalChalk Support rejected as spam
Some of our customers have reported that they are unable to send email to DigitalChalk Support (email@example.com) because the email is being rejected as spam and returned to them. If this is happening to you, it is possible that your email server IP address has been flagged by one or more blacklists for sending suspected spam content. Your email server IP address can be flagged as blacklisted for one of the following reasons:
- A compromised email account
- An Open Relay
- Your organization is sending mass emails from that email address. Mass emailing is the most likely cause of blacklisting.
