This attachment cannot be sent. Allowed are PDF, PNG, JPG, GIF and WebP,
plus calendar (.ics), text (.txt) and CSV (.csv) files as UTF-8 text. The
type is checked on the first bytes of the file, not only on its name, so the
extension must match what the file really is. Never allowed: anything that runs
or renders as a page (exe, js, html, svg, zip and the like), and a PDF with
scripts, launch actions or embedded files. index says which attachment;
allowed lists the extensions.
