Secure Mail Gateway
Avoid unwanted entries in spam blacklists
For customers who do not want to operate their own mail server in the Open Telekom Cloud, we offer free anti-virus and anti-spam functionalities for your outgoing email traffic with the Secure Mail Gateway. The service thus prevents your sender IP from being put on a blacklist of unwanted senders by anti-spam databases and from getting blocked. In this way, the Secure Mail Gateway protects your reputation and ensures secure delivery of your customer mailings.
Three good reasons for the Open Telekom Cloud Secure Mail Gateway
How Secure Mail Gateway prevents entries in spam blocking lists
Good / Bad Gateway / Anti-spam
Good/Bad routing prevents you as the sender from permanently ending up on block lists of anti-spam providers. It first checks the email to be sent and assesses how likely it is to be considered spam. If the message is inconspicuous, it is sent via one of the "good" gateways. In the case of suspected spam, on the other hand, this suspicious email is sent via the "bad" gateway. Then there is a higher chance that the gateway will be put on a block list. Should this occur, the Support will check whether this can be remedied. However, there is no guarantee of this.
Secure Mail Gateways check all outgoing mails for viruses. Messages that contain a virus are rejected. The sender of the mail receives a Non Delivery Report (NDR).
The automated blacklist monitoring checks the entries of ip blacklist service providers and informs you if your IP address has been included in a blacklist. For this purpose, a script is executed daily at 5 am. If it finds an entry, it informs the T-Systems service, which immediately, if possible, submits a deletion request to the respective blacklist provider.
Sender Domain Check
This function protects against misuse by checking whether the sender address is a valid domain before sending a mail. This means that the domain has a public MX record or at least a public A record that assigns an IP address to the address. Mails with sender addresses that do not meet these criteria are discarded.
