Role required: email_account_admin

About this task

You can specify two types of email address filters:
  • Allow List: A list of allowed domains and email addresses
  • Deny List: A list of disallowed domains and email addresses
You can also specify exceptions to the allowed or disallowed domains and email addresses.

Procedure

  1. Navigate to System Mailboxes > Administration > Email Address Filters, and then select New.
  2. Enter the Name of the address filter.
  3. Select the filter Type:
    • Allow List: Allow all specified domains. All other domains are disallowed.
    • Deny List: Disallow all specified domains. All domains that don’t match the denied list domains are allowed.
  4. In the Domains field:
    1. Select the lock icon to unlock it and access the domains controlled by this filter.
    2. Select an existing domain or enter a new domain:
      • If the filter Type is Allow List, select the Search icon. Select the domains for which all email addresses are allowed. To add a new domain, select New, enter the Domain, and select Submit.
      • If the filter Type is Deny List, select the Search icon. Select the domains for which all email addresses are disallowed. To add a new domain, select New, enter the Domain, and select Submit.
      Note: You can specify a wildcard (*) in the domain name, for example*.com. If you create an email configuration that has multiple email address filters, all the filters evaluate the given email addresses. The filters determine whether the addresses are valid and the message can be sent as outbound email.

      By default, the maximum number of domains that you can associate with an email address filter is 100. You can reconfigure this limit by setting the glide.email_address_filter.max_domains property.

    3. Select the lock icon to lock the Domains field.
  5. Specify any email addresses that are Exceptions to the domains specified in Step 4.
    1. Select the lock icon to open the Email Address Filter Exceptions [sys_email_address_filt_except] table.
    2. Click the search icon to choose an existing email address.
    3. To add a new email address, select New, enter the email address exception, and select Submit.
      Note: You can specify a wildcard (*) in an email address exception.

      By default, the maximum number of exceptions that you can associate with an email address filter is 1000. You can reconfigure this limit by setting the glide.email_address_filter.max_exceptions property.

    4. Select the lock icon to lock the Exceptions field.
      The exception is added to the Email Address Filter Exceptions [sys_email_address_filt_except] table.
  6. Select Submit.
    The email address filter is added to the Email Address Filters [sys_email_address_filter] table.
