On the mutt home page there is a link to my:- http://lacebark.ntu.edu.au/mutt.html under a heading of "Additional MIME types patches" and "Mutt for chemists patches". These originally refered to version 95.6i. I have now updated these to refer to version 1.2.5. The main details are actually at:- http://lacebark.ntu.edu.au/mutt/chemutt.html but there is a link from mutt.html. The pages now refer only to the addition to mutt of the MIME type chemical. The problems discussed earlier for MIME types models and visual have been fixed somewhere between 95.6 and 1.2.5. Chemists have been using the MIME type chemical, particularly for web pages, since 1994. Although it has never been officially accepted, this has not deterred the chemistry community. In web pages it is used particularly to send data for molecules that are then displayed with the Chime pluggin for Netscape or Internet Explorer. However there are many different subtypes. The chemistry MIME type can be used with other mailers such as pine or elm without change to the code. mutt is stricter so it has to be specifically added to mime.h, globals.h and parse.c. My page may be useful for anyone who wishes to add any other MIME type, as well as of course to chemists using mutt.
