How do I notify SMX of a misclassified email?

In order for SMX to investigate an email problem the help desk requires a copy of the misclassified email. This means that the original email must be sent to emailsupport@smxemail.com. The SMX help desk will automatically issue you with a case number to be included in all future correspondence related to this case.

These are the steps to follow when sending the misclassified email to the SMX support desk with most common mail clients and webmail clients:

  1. Launch your email client
  2. Create a new message and address it to emailsupport@smxemail.com
  3. Drag and drop the misclassified email into the newly created message, it will now appear as an attachment

N.B. In Mac OS X Mail, use the "Forward as Attachment" option in the Message menu or via right-click.
