Note that any mailer that does this violates the MIME specifications, which specifically warn against the presentation of content-types not known to be safe, against a mail reader implementing the ability to present arbitrary content via a content-type parameter (e.g. "filename"), and recommends that the most that should be done with unknown content-types is to offer to save the content to a file. The working group that produced MIME went to a lot of effort to research the hazards associated with transmission of arbitrary content by email, and to craft a series of recommendations that would minimize the harm done. One vendor in particular deliberately ignored those recommendations. It also produced mail readers that didn't properly label content on outgoing mail and ignored the content-type parameter on incoming mail, instead looking at the suffix of a nonstandard "filename" parameter (which was only intended for use with application/octet-stream). When I was on IESG, a program manager with that company (in charge of an email product) assured me that this decision was deliberate, as it was thought that it would maximize their company's penetration in the market. Obviously, it did serve that end, and other vendors of mail readers for that platform were forced to emulate (to some degree) the nonstandard and dangerous behavior of the market leader's products. This decision has cost the network billions of dollars, including significant costs to people who do not use that company's software products (and who therefore aren't bound by its EULAs). Words that come to mind to describe this include: Willful, Criminal, and Negligence. Another word that comes to mind: Prison. As in "some people need to spend a lot of time there".
