Define how email address filters apply to inbound and outbound email.

## Before you begin

Complete the steps in [Set email address filters](https://servicenow-prod.fluidtopics.net/vJ4~2EvwsRMaOL6aRo2mow "Specify which domains and email addresses are allowed or disallowed.").

Role required: email_account_admin

## About this task

You can use a combination of allowed list and denied
list email address filters in a system address filter.  
A system address filter blocks a domain or address that appears only on denied lists and never on allowed lists. To ensure that a system address filter effectively blocks a certain domain or address, check for the following:

* The domain or address is included in at least one denied list
* The domain or address is not included in any allowed list
{#create-system-address-filter__ul_lm2_jlz_llb}

## Procedure

1. Navigate to AllSystem MailboxesAdministrationSystem Address Filters, and then click New.
2. On the form, fill in the fields.  
   {#create-system-address-filter__table_plg_jv2_jlb__entry__2}

   | Field | Description |
   |-|-|
   | Name | Name of the system address filter. |
   | Active | Option to activate the system address filter. |
   | Type | Type of system address filter. Select one of the following: Outbound :   Control which domains and email addresses can receive email from your instance. Select this option if you plan to use the system address filter for an SMTP server. Inbound :   Control which domains and email addresses can send email to your instance. Select this option if you plan to use the system address filter for an IMAP or POP3 server. |
   | Application | Application scope of the system address filter. |
   | Default | Option to use this system address filter as the default inbound or outbound filter. To control senders and recipients for a specific email account, leave this field cleared. |
   | Short description | Description of the system address filter. |
   | Email Address Filters | Email address filters to apply to the system address filter. By default, the maximum number of email address filters that you can associate with a single system address filter is 100. You can reconfigure this limit by setting the glide.email_system_address_filter.max_address_filters property. |
   [ ]

   {#create-system-address-filter__table_plg_jv2_jlb}
3. Click Submit.

## Result

A default outbound filter applies to all active SMTP email accounts automatically. A default inbound filter applies to all active IMAP or POP3 email accounts automatically.

For a non-default filter, the next step is to apply the filter to an email account
manually. For more information on applying a filter to an email account, see [Create an email account](https://servicenow-prod.fluidtopics.net/niaNGg06_trUabzBrJFu7Q "You can create email accounts in addition to the accounts provisioned for you.").
