0000122: Office 2007 files get caught by amavisd as multipart with binary attachments

Description

See the forum threads for details

you can also prevent this by removing the block for binary extensions but this opens up a bit of a security hole so opted to pass extensions with xlsx, docx and pptx (formats which don't contain macros)

Additional Information

Work around is

Create a file called /etc/amavisd/override.conf containing:-

$banned_filename_re = new_RE(
[ qr'(\.xlsx|\.docx|\.pptx)$' => 0 ], # allow MS Office 2007 plain files
);

Then run 'service amavisd restart'
