Setting the file name of the attached safe report

[Namespro.ca]

Hi there,

Currently, when report_safe is set as 1, the original message is included
as an attachment with the following headers:

Content-Type: message/rfc822; x-spam-type=original;
Content-Description: original message before SpamAssassin
Content-Disposition: attachment
Content-Transfer-Encoding: 8bit

I am wondering if it is possible to explicitly define a file name for this
attachment, such as:

Content-Type: message/rfc822; x-spam-type=original; *name="original.eml";*
Content-Description: original message before SpamAssassin
Content-Disposition: attachment
Content-Transfer-Encoding: 8bit

Thanks!
