G DATA 365 | Mail Protection

Instructions for setting up the connector and the rule. What must be observed?

By creating the rule, you intervene in the message flow. It is important that when you set up this e-mail does not run into the void.

The rule recognizes from the domain you have entered that an e-mail is to be sent via the outbound connector to the G DATA 365 | Mail Protection. As soon as the e-mail has been transferred to the connector, it is delivered to your Microsoft Exchange Online. Microsoft Exchange Online no longer asks whether the e-mail has been accepted by G DATA 365 | Mail Protection.

Therefore, the rule may only be enabled if the mail server exists in the G DATA 365 | Mail Protection and your domain has been verified.

Otherwise, the incoming e-mails will be lost.

If your MX record points to Microsoft Exchange Online, please be aware of the following factors

  • When setting up the product for the first time, always proceed in the order described under Flowchart for the product launch G DATA 365 | Mail Protection.

  • Always check that new domains are displayed correctly and verified in G DATA Web-Portal before adding the domain to the rule.

  • Do not delete a server from the G DATA Web-Portal as long as a rule is still active in the Microsoft Exchange Online.

  • Domains that are not included in the rule but are active in G DATA 365 | Mail Protection do not have a scan of incoming e-mails. However, the e-mails are checked in the mailboxes as part of the rescan.

  • Domains that are included in the rule but are not verified in G DATA 365 | Mail Protection will result in the loss of incoming emails for them.

If compliance with the above points is ensured, it is not necessary to change the MX record. If you cannot ensure that this procedure is always followed, changing the MX record directly to G DATA 365 | Mail Protection can minimize the risk of e-mail losses.
But beware! Incorrectly configured DNS can also lead to loss of e-mails!
