Policies - Delivery Failure Retry Count Policy

This article contains information on configuring a Delivery Failure Retry Count policy in Mimecast, including steps to define retry attempts, policy settings, and customization options for email delivery management.

Configuring a Delivery Failure Retry Count Policy

You can configure a Delivery Failure Retry Count policy, by using the following steps:

1. Log in to the Mimecast Administration Console.
2. Navigate to Policies | Gateway Policies.
3. Select Delivery Failure Retry Count.
4. Either select the:

• • Policy to be changed.
  • New Policy button to create a policy.

5. Complete the Options section as required:

Field / Option	Description
Policy Narrative	Provide a description for the policy to allow you to easily identify it in the future.
Delivery Attempts Before Bounce	Specify the number of attempts Mimecast should make before issuing a bounce to the sender. A value of "0" means the policy doesn't apply. The value specified overrides the default retry count for your account, but we recommend a value no bigger than 30.

6. Complete the Emails From and Emails To sections as required:

Field / Option	Description
Addresses Based On	Specify the email address characteristics the policy is based on. This option is only available in the "Emails From" section. The options are: Return Address (Mail Envelope From): This default setting applies the policy to the SMTP address match, based on the message's envelope or true address (i.e. the address used during SMTP transmission). Message From Address (Message Header From): Applies the policy based on the masked address used in the message's header. Both: Applies the policy based on either the Mail Envelope From or the Message Header From whichever matches. If both match the specified value the Message Header From is used.
Applies From / To	Specify the Sender characteristics that the policy is based on. For multiple policies, you should apply them from the most to the least specific. The options are: Everyone: Includes all email users (i.e., internal and external). This option is only available in the "Emails From" section. Internal Address: Includes only internal organization addresses. External Address: Includes only external organization addresses. This option is only available in the "Emails From" section. Email Domain: Enables you to specify a domain name to which this policy is applied. The domain name is entered in the Specifically field. Address Groups: Enables you to specify a directory or local group. If this option is selected, click on the Lookup button to select a group from the Profile Group field. Once a group has been selected, you can click on the Show Location field to display the group's path. Address Attributes: Enables you to specify a predefined Attribute. The attribute is selected from the Where Attribute drop-down list. Once the Attribute is specified, an attribute value must be entered in the Is Equal To field. This can only be used if attributes have been configured for user accounts. Individual Email Address: Enables you to specify an SMTP address. The email address is entered in the Specifically field.

7. Complete the Validity section as required:

Field / Option	Description
Enable / Disable	Use this to enable (default) or disable a policy. If a date range has been specified, the policy will automatically be disabled when the end of the configured date range is reached.
Set Policy as Perpetual	If the policy's date range has no end date, this field displays "Always On" meaning that the policy never expires.
Date Range	Use this field to specify a start and / or end date for the policy. If the Eternal option is selected, no date is required.
Policy Override	This overrides the default order in which policies are applied. If there are multiple applicable policies, this policy is applied first unless more specific policies of the same type are configured with an override.
Bi-Directional	If selected, the policy is applied when the policy's recipient is the sender, and the sender is the recipient.
Source IP Ranges (n.n.n.n/x)	Enter any required Source IP Ranges for the policy. These only apply if the source IP address used to transmit the message data, falls inside or matches the range(s) configured. IP ranges should be entered in CIDR notation.

8. Click on Save and Exit.
