it sometimes funny, i'm working with mutt since about 10 years, (the 5 years before i was using elm) and just found out how i can view pure text/html-Mails without fiddeling with piping and things.
in .muttrc does the trick.
but now mutt also prefers the text/html-part of multipart/alternative-mails, this is going to far for me. i want the text/plain-part if available. mutt has also a solution here:
alternative_order text/plain text/html
and done. no more piping to html2text. One day i'll read through the whole manual again...
