When I first went onto the internet from home in the 1990s I used a small local ISP. The guy came along to set it up - and installed the Pegasus email application. Several ISPs later it still does everything I want - including the facility for a "raw" view of the headers and contents. It also doesn't render HTML picture content by default.
