A blackhole email address is as an e-mail address that when emails are sent to, they are immediately discarded.
This is particularly useful for sub-production instances where you want emails to be sent/processed, but do not want them to leave the ServiceNow mail servers.
| IMPORTANT: This will ONLY work if your instance is configured to use ServiceNow's mail server for SMTP. |
Most of the time, this is configured on SMTP mail servers by specifying a certain email addresses or a domain.
ServiceNow has the following configured on the SMTP mail servers.
# blackhole domains example.com discard: .example.com discard: test.com discard: .test.com discard: nobody.com discard: .nobody.com discard: dummy.com discard: .dummy.com discard: yourcompany.com discard: .yourcompany.com discard:
Aslong as the email address ends with any of the above mentioned domains, it will be discarded by ServiceNow's SMTP mail server.
ie. nobody@example.com; john.smith@dev.example.com; blackhole@acme.yourcompany.com;
