I'm using the same ~/.muttrc I've been using and lately I've reinstalled my debian and used 2.2r0 (apt-get to the latest) and kernel 2.4.1 (no ReiserFS support yet). The funny thing I noticed is that the "From:" line in mutt doesn't show my address although I've tested it and receivers do see my email addy. The mutt version I have now is 1.2.5-4.
Anyone else experienced this?
