Managing the white list

You can add trusted hosts to a white list and configure the spam checks you want to bypass for each entry in the list. This ensures that trusted mail (such as newsletters or bulk mail from your whitelisted senders) is not blocked. The White List tab on the SpamLogic Settings page displays which senders have been whitelisted and which spam checks are bypassed for each entry.

Tell me about...

• What can I add to the white list?

  You can add Mail Servers or Email addresses to the white list. You can specify:

  Type	Example
  IP addresses	192.168.1.125
  IP address ranges	192.168.1.0-192.168.1.255
  CIDR notation networks	192.168.5.0/24
  Mail server hostnames	hostname.company.com
  Email addresses	user@company.com
  Email domains	company.com
  Sub-domains	mail.company.com

  Add Comments to whitelist entries to identify them more easily. You can enter comments of up to 128 characters in length.

  Use wildcards (*) to specify a range of entries. Show me

  White list entry	Type	Includes...
  192.168.1.125	Mail Server	192.168.1.125
  192.168.*	Mail Server	any IP address in the range 192.168.xx.xx
  192.168.1.*	Mail Server	any IP address in the range 192.168.1.*
  hostname.company.com	Mail Server	hostname.company.com
  *.company.com	Mail Server	anyserver.company.com
  fred@company.com	Email	fred@company.com
  *red@company.com	Email	fred@company.com filtered@company.com code.red@company.com
  company.com	Email	everyone@company.com
  mail.company.com	Email	everyone@mail.company.com
  *.company.com	Email	everyone@mail.company.com everyone@users.company.com everyone@company.com
  *	Mail Server/Email	not supported.

• What happens if there is a conflict between two entries?

  Example 1: I want to add *.company.com to the white list and select spam checks for all sub-domains. However, I also want to add company.com with no spam methods selected. What happens?

  • A message from mail.company.com will be whitelisted.

  • A message from company.com will not be whitelisted.

  The Gateway always applies the most specific match first. If entries are equally specific, the selected spam checks are bypassed if defined by either entry.

  Example 2: I want to add IP range of ... .124 - .255 to the white list and select certain spam checks for all IP addresses in this range. However, I also want to add range .164 - .192 with other spam methods selected. These IP address ranges have overlapping entries between .164 and .192 What happens?

  • All spam checks that you select for both IP address ranges will apply to the overlapping entries.

  If there are overlapping IP address ranges, the Gateway is additive when applying spam checks. All spam checks selected for IP address ranges apply if there are any overlapping entries in the ranges.

• Which spam checks can be bypassed?

  You can configure each whitelisted sender to bypass a combination of any of the following spam checks:

  • Junk Email: Messages will be accepted from the specified host without being subject to trust scoring. The option applies to Confirmed Junk Email and Suspected Junk Email.
  • Greylisting: Messages from the specified host will not be greylisted.
  • DKIM: Messages will be accepted from the specified host, even if they fail DKIMDomainKeys Identified Mail validation checks.
  • SPF: Messages will be accepted from the specified host, even if they fail Sender Policy Framework (SPFSender Policy Framework) validation checks.
  • DMARC: Messages will be accepted from the specified host, even if they fail Domain-based Message Authentication, Reporting & Conformance (DMARCDomain-based Message Authentication, Reporting & Conformance) verification checks.
  • Spoof Detection: Messages will be accepted from the specified host, even if they are identified as being spoofed.
  • Real-time IP Blocklists: Messages will be accepted from the specified host, even if they appear in an RBL.
  • If Reputation Bad: Messages will be accepted from the specified host, even if TRUSTmanager returns a reputation of Bad. For more information, see TRUSTmanager Reputations.

To import a white list:

You can import a text file of white list items. The file must contain each white list item on a separate line. The file can be a maximum of 2 Mb in size or 100,000 valid entries.

1. From the Policy Center Home page, click SpamLogic Settings. The SpamLogic Settings page appears.
2. Click the White List tab.
3. Click Import white list.

4. In the Import SpamLogic White List dialog box, click Browse... and select the file containing the white list items you want to import.

   Select the Replace existing matching entries? check box to replace the existing list with the contents of your new import file. If you leave this check box clear, the Gateway merges the new and the existing lists. Duplicate items are ignored and appear once in the white list.

5. Select the type of list you are importing: Mail Server or Email.

   When importing a text file of white list items, your file should contain either Mail Server or Email items as the Gateway does not support both types in the one import file.

6. Select the spam checks you want the sender to bypass.

7. Click Import.

   The new entries are displayed in the White List.

8. Apply configuration.
