When I use the editable email plugin to attach a zip file, the plugin attachs the email TWICE, with the same name, and slightly different file size. 

I am 100% sure that the zip file is complete prior to the email plugin sending it out, and even used a sync shell command.  I have tried HTML and plain text and 2 different charactersets.   No matter what I do, every zip file that's attached comes through TWICE through jenkins plugin. 

The issue seems to be with attaching a ZIP (or GZIP) file with any other type of file.  If all files are non-zipped/gzipped, it works fine... but the moment you have a mixture of  at least 1 zip/gzip file, the email is corrupted by the plugin. 

I do not know if picked the right component above, sorry.
