* After running MTA Engine debug using "`fw debug in.emaild.mta on TDERROR_ALL_ALL=5`", the logs in `$FWDIR/log/mtad.elg` show that the function "`runPostProcessing`" is called properly.  

  ```
  [mtad 6668 4027499008]@HOSTNAME[DATETIME] �[EMAIL_MTA (INFO)] shouldRunPostProcessing() - 4b66MD5fklz8FgpJ :Found malicious attachment.

  ```

* This error appears in `$FWDIR/log/mta_custom_post_processing.elg`:  

  ```
