Adjusting the Primary Environment Settings

Under Primary Environment Settings, you can adjust the settings for receiving and sending emails.

You have activated Spam and Malware Protection.

Spam and Malware Protection requires several primary environment settings related to receiving and sending emails. For more information about the functions, see chapter Primary Environment Settings.

  1. Log in to the Control Panel with your administrative credentials.
  2. From the scope selection, select the domain for which you would like to adjust the primary environment settings.
  3. Navigate to Security Settings > Spam and Malware Protection.
  4. Under Domain, select the domain for which you would like to adjust the primary environment settings.
  5. Optional: If you have selected an alias domain that inherits the settings from the primary domain, toggle the Inherit from primary domain switch.
    The switch is grayed out. The settings in the module are enabled.
  6. Under Destination, set the destination server of incoming emails. You have two options:
    • If you have your own email server, tick the IP/Hostname checkbox and enter the IP address or the hostname of the destination server in the field. Enter at least one IP address or hostname. Optionally, you can also enter the port number and the priority. Follow the input format IP/Hostname:Port#Priority and use a semicolon to separate several entries from each other.

    • If you use the email service Hornet.email, tick the checkbox Hornet.email. Select the size of the mailboxes. For Spam and Malware Protection, no other primary environment settings are required.

    • If Hornetsecurity is your email provider, tick the checkbox POP3/IMAP. Under Mailbox size, enter the size of your POP3/IMAP mailbox (allowed values: 100-1024 MB).

    Note:

    This destination server is called the primary environment in the Control Panel. By default, the inbound email traffic of the mailboxes of the domain is routed to the primary environment. To route the inbound email traffic of an individual mailbox to a different server instead, the mailbox can be assigned a a secondary environment (see Secondary Environments) instead of the primary environment (see Changing an Environment).

  7. Optional:
    Note:

    This step is not required for 365 Total Protection customers.

    For other customers, this step is optional but strongly recommended. The relay IP addresses specified under Relay IP addresses for outgoing emails are also required for signing and encrypting emails with the services Signature and Disclaimer and Email Encryption. If no addresses are specified, none of both services will be able to process any emails.

    If you want to enter the IP addresses of your relay mail servers manually, toggle the switch Relay IP addresses for outgoing emails.

    An input field for IP addresses is displayed.

    Figure 1: Define relay IP addresses for outgoing emails
  8. Optional: Enter the IP addresses of your relay mail servers in the field under the switch Relay IP addresses for outgoing emails. If the switch is on, this field may not remain empty.
    Note:

    Here, you can enter several relay IP addresses with suffixes not larger than /24, separated from each other by commas. The field may only contain up to 65,535 characters.

  9. Optional: If you want to activate bounce management to prevent incorrect bounce messages, tick the checkbox Bounce management (recommended).
  10. Set up the user check under the section User check. You have four options:
    Figure 2: Set up user check
    • Control Panel: If you tick this checkbox, Spam and Malware Protection checks whether the recipient address is listed in the user list of the Control Panel.

    • LDAP: If you tick this checkbox, Spam and Malware Protection checks whether the recipient address is listed in your directory service.

    • SMTP: If you tick this checkbox, Spam and Malware Protection checks the recipient address using an SMTP callback. To do so, Spam and Malware Protection asks the destination server of the recipient address whether the recipient address valid. Usually, the destination server is determined on the basis of the domain part. If you want to use other destination servers for the user check with SMTP, toggle the switch Alternative IP address for user check and enter the IP address in the input field.

  11. Click on Save.
