How do I find the sender hostname used to send emails from ServiceNow?

[Heather9]

Our security team is needing to add a specific rule for ServiceNow emails to our spam filter and is needing the sender hostname to do so.  I've tried looking through the email properties in my instance but I am not finding anything.  Any help would be appreciated.

Should be found under:

System Mailboxes > Email Accounts > ServiceNow SMTP

This appears to be showing the From Address but not the sender hostname.

The Sender IS the From...

Whatever you put in the From address there will be reflected in the From SMTP header of the email itself.  Emails from the ServiceNow instance ALL originate from the configured email address.

If you want to actually know "who" sent the email, you'd have to embed fields in the email notification itself and then parse those out.

Apologies, I just noticed you said "hostname".

The hostname should always be your instance name.
