Thank You for the Replies!

I just updated the code to reflect these changes. Alas, I received the same result.

The MIME section of the message has the following information:

----boundary_0_a3691d3d-2344-4a85-be2b-f56c7108c983
Content-Type: application/octet-stream;
 name="settings.ace.2015-06-29.181909.(Error).log.7z"
Content-Transfer-Encoding: base64
Content-Disposition: attachment
[download]

Is there something I need to tell MIME::Tools specifically for Content-Transfer-Encoding?

Thank You!
