There is an error message that attempts to send to firstname.lastname@example.org. The subject line is "Error while performing clean up archive logs and data". I also need to determine the cause of the error, but first I would like to track down where this destination address is coming from.
I checked the mail server parameters and all the Maintenance properties on the Administer > Setup > Application Settings and I don't see that email address anywhere. I searched the server-configure.properies file for "admin" and didn't find the email address.
I looked through the system mail notifications and targets and didn't find it there either. Other mail notifications are sent successfully so I don't believe the mail server set-up is an issue.
