How do I delete entries from the Recipient Access Table (RAT)?
The RAT defines which recipients will be accepted by a public listener. The table specifies the address (which may be a partial address or hostname) and whether to accept or reject it. You can optionally include the SMTP response to the RCPT TO command for that recipient. The RAT typically contains your local domains.
Connect to the GUI
Select the Mail Flow Policies
Select Recipient Access Table (RAT)
Select the entry you like to delete
In the menu for this entry select delete
You can also delete the RAT entry from the CLI.
To delete an entry from the RAT, follow these steps:
Login to the Email Security Appliance command line interface (CLI).
Type "listenerconfig". The list of currently configured listeners are displayed.
Type "edit" and then enter the number or name of the listener you wish to change. Information about that listener is displayed followed by a list of options.
Type "rcptaccess". The system displays how many entries are in the RAT and the default access setting (e.g. REJECT). A list of command options is also displayed.
Type "print". All currently configured RAT entries are displayed followed by a list of command options. Examine this list and identify which entries you wish to delete.
Type "delete". The system prompts you for the entry you wish to delete.
Type the address to delete.
To delete additional entries, repeat Steps 6-7.
Return back to the CLI top-level prompt, and then type "commit" to commit your changes.
