We have a mass emailing tool (.net based) that we developed in house. html editor. and sends via html and text formats.
within the body we have an absolute URL path to a PDF on our server. some of our subscribers are stating that when they click on the link they get a message box that the file is an executable file and whether they should run it or not…
why would that happen… and only to a certain group?
To resolve your problem, you need to indicate MIME type of content. In this case: application/pdf
