3.07
In 3.7.x, if an email is processed which has an attachment, and the attachment's filename contains invalid characters that can't be represented on the JIRA filesystem, then JIRA will renames the file:

The problem here is that neither JIRA nor the user can now infer the type of the file. It could be a PDF, an image.. anything.
Rather than rename the whole file, JIRA should break filenames into name + extension, and sanitize each individually. Typically this will result in the extension being unharmed, yielding filenames like renamedFile~1.pdf.
