    Table 1. Advanced Transfer Controls options



    Ignore message priority

    Choose one:

    • Enabled - The Router sends all messages as Normal priority.
    • Disabled - (default) The Router honors message priority settings assigned by the sender or another server process.
    Note: Do not enable this setting if you restricted Domino® to routing messages of a specified size as low priority and want to confine routing of large messages to the specified low priority routing time.

    Dynamic cost reset interval

    The time, in minutes, after which the Router resets the costs for the various connections. For example, if the cost reset interval is 15 minutes and a network failure caused the Router to increase a connection cost from 1 to 2, the Router resets the connection cost to 1 after the 15-minute cost reset interval.

  7. Complete these fields in the Additional Controls section, and then click Save & Close:
    Table 2. Additional controls



    Restrict name lookups to primary directory only

    Choose one:

    • Enabled - The router can only look up names and groups in the Domino® Directory for the server's Domino® domain. The router cannot look up names and groups in other directories that are available through Directory Assistance or Directory Catalog.
    • Disabled - (default) The router can look up names and groups in any directories available from the server.

    Cluster failover

    Choose one:

    • Disabled - If a recipient's server is unavailable, the Router does not automatically route mail through a clustered server.
    • Enabled for last hop only - (default) When the Router detects that a recipient's mail server (the last hop in the routing path) is unavailable, it attempts to locate a clustered server and transfer the message to that server.
    • Enabled for all transfers in this domain - When the Router detects that a server for any hop in the routing path is unavailable, it attempts to locate a server clustered with that hop server. If the Router can find another clustered server, it transfers the message to that server.

    Hold undeliverable mail

    • Enabled - When the Router cannot transfer or deliver a message, it leaves the message in MAIL.BOX rather than generate a delivery failure report. Select this option if you want to be able to examine messages with failures. You can then access these messages and either release them, forward them, or delete them
    • Disabled - (default) When the Router cannot deliver a message, it generates a delivery failure report.
    Note: If you configure MAIL.BOX to hold undeliverable messages, examine the database frequently to check for accumulated messages.


The change takes effect after the next Router configuration update. To put the new setting into effect immediately, reload the routing configuration.
