We have configured two dedicated mailboxes in ServiceNow to handle inbound email actions:
IT Support
This mailbox was configured first and is restricted to only accept emails from domains explicitly defined in the Inbound Email Actions.
If no specific inbound action is triggered, a catch-all inbound action is executed. This action sends a notification back to the sender, directing them to submit a ticket through the IT Service Portal.
HR Support
This mailbox was implemented later and is configured to accept emails from all domains, including external senders such as retirees and former employees.
We enabled the email property that allows emails from any domain.
Objective:
We want to maintain domain restrictions for IT (only allow emails from specified domains) while allowing all domains for HR. The IT mailbox should continue using the catch-all inbound action to notify users directing them to submit a ticket through the IT Service Portal.
