E-mail solutions for a secure and efficient customer approach
Protect yourself from blacklisting with the Secure Mail Gateway
If you send large volumes of emails to customers, anti-spam databases may blacklist you from unwanted senders. The Secure Mail Gateway prevents this and guarantees that your mails are delivered securely and reliably.
If you want to operate your own mail server in the Open Telekom Cloud, you need certain open ports to send through the firewall. Mail BGP makes these available to you.
