This 'Send to Me' link shows a different address than the MailGate server on mouse hover.

1. Check the "Host Name:" field under Admin UI > Administration > Network Settings > Appliance. The entry is reflected in the 'Send to Me' link on the Spam report.
3. Modify the value to reflect the MailGate server name if the link shows incorrect address.

NOTE:   In cluster setup, the link will take the address of the primary box.
