Mutt is completely behaving itself and I'm very happy with that. An additional tweak I've made is to pipe Mailtos to a fine script by Martin Krafft http://svn.madduck.net/pub/bin/mail/mailto-mutt. There's a few scripts out there to handle mailtos but Martins' works splendidly with the browser I'm using, Iceweasel. The only things I modified in his script were to route the /path/to/handler to the mailto-mutt script and to respecify the xterminal to aterm, the terminal emulator I use. And don't forget to make the script executable.

I've given some thought to using a text browser to replace Iceweasel, but generally my websurfing is pretty image dependant. I also think that, as a visual media, that's not a bad thing.
