We've received the following email for a developer script exception:

"Subject: Undeliverable: Developer script exception from Tripp Lite : Case_Product_Filler : Case_Product_Filler: execution of BeforeUpdate caused by: System.DmlException: Update failed. First exception on row 0 with id 5003800000hQp5vAAC; first error: FIELD_CUS...

The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk."

The email referenced in the error message (nvajor@tripplite.com) is no longer an active user/employee.  We're trying to figure out where this can be changed/removed so that the emails don't persist.

It doesn't seem to be included in the trigger.  Where would we go to modify this information?

Thank you.
