Mutt (0.99.1) and Elm 2.4

[rg pobox1015 freeserve co uk]

Just downloaded and compiled pine 4.05 - great!

Just downloaded Mutt 0.99.1 also and found that it too (as elm 2.4) sends
out X-BadReturnPath: ...using from: etc...etc... It's embarrasing sending
mail with that sort of crud on it.
Anyone know how to fix it? The rest of it is just great, message sorting
and colors etc..

Happy new year to all.
