Hi John,
I wanted to share the update from our support ticket for anyone else who may be experiencing this problem.
The Proc folder is available for third-party programs to intercept the messages and handle them. It essentially acts as a replacement for the SmarterMail spool. Therefore, any handling that the SmarterMail spool would manage is now the responsibility of the program that's handling the Proc folder.
When the email delivery fails during the SMTP session, we write "Failed" into the HDR file as an indicator to our spool that the message is bad or incomplete, so the SmarterMail spool knows to immediately remove it. Our spool also has code that will clean up any other orphaned files. When the Proc folder is enabled, those files will be sent to the Proc folder, and it is the responsibility of the corresponding program to handle them accordingly. In short, whatever program is looking for mail in the Proc folder would be responsible for clearing out any failed or orphaned files.
You mentioned that you are seeing this problem when using Declude Reboot. Therefore, I would encourage you to contact Mail's Best Friend and request their assistance in resolving this.
Kind regards,
