Realtime Whitelists (Server Level)

How to get here

Realtime Whitelists are whitelist databases that store IP addresses and domain names of trusted sources. E-mail messages that find a Realtime Whitelist match will be considered trusted and further validation checks as set by the IMail Administrator will be bypassed.

Trusted Realtime Whitelist

A match made with a trusted realtime whitelist will bypass the following validations.

• DomainKeys will be bypassed if enabled.
• IP Reputation (if Premium Anti-spam is installed) if enabled.
• Realtime Blacklists will not be checked.
• Content Filtering checks will be skipped.
• Premium Content Filtering (if installed) will be bypassed if enabled.
• Attachment Blocking is skipped (checkbox is set by default). This check box can overridden by the IMail Administrator.

Important: Updates made to the Realtime Whitelist will not successfully update until the "Save" or "Apply" button has been clicked.

Note: Be sure that the SMTP and Queue Manager services have been restarted after updates have been applied.

Realtime Whitelist

Important: Fields cannot be left blank or contain spaces.

• Realtime Whitelist Name. Enter a name in the text box to identify a new whitelist. This can be any name that you want, and will be used in log lines to identify the realtime whitelist entry.
• Type. Select the type of lookup that the realtime whitelist performs from the list box.
  • ADDR (ADDRESS). This type of whitelist uses a message's "FROM" address to determine whether the message is whitelisted.
  • DNS. (Set by Default) This type of whitelist checks the IP address of the connecting SMTP server against spam databases to determine whether the message is whitelisted.

    Tip: Be sure that the IP address of your DNS Server matches the DNS Server as set in Queue Manager > Service Properties.

  • HELO. This type of whitelist checks the domain supplied in the HELO or EHLO command to determine whether to accept the message. The domain name that is given in the HELO/EHLO command must match the IP address.
  • RHS (RIGHT-HAND SIDE). This type of whitelist checks the information following the @ symbol supplied in the "MAIL FROM" command to determine whether the message is whitelisted.
• Server. Enter the domain name or IP address of the DNS server to contact for whitelist queries, where it will relay the DNS Query to the DNS server for the whitelist. By default this text box contains an asterisk (*), to indicate use of the default IMail DNS Server (as set in Queue Manager > Service Properties) for whitelist queries.

  Note: Use of an asterisk eliminates the need to enter the IMail DNS Server address.

• Query Domain. In the text box, enter the domain to query in the zone file. This name usually matches the server domain name. However, sometimes a whitelist will contain multiple zones to query on the same server. When this happens, the server name and the query domain will be different. The only way to know this is to read the documentation for the whitelist being used.
• Enable. Select the check box to enable the whitelist.
• Add. Click this button to Add to Realtime Whitelist page.
• Edit. Select an item and click this button to Edit the Realtime Whitelist to the Realtime Whitelist.
• Delete. Select an item to delete and click the Delete button.

Important: Updates made to the Realtime Whitelist will not successfully update until the "Save" button has been clicked, and the message "Your changes have been saved" is displayed at the top.

Save. Click to save your settings. An "Update Successful" message and the time of the update appear.
