Issue



There are spam submissions in the SESC spam submission folder.  The spam submissions stay in the submission folder and are not processed by SESC. The SESC console shows the Failed counter increasing.  This counter is displayed at the top of the SESC console.

Conditions

  • The To or From field of the email has an underscore (_) in the domain name of the email address.

The following is an example:
