I created once a quick and dirty mapping, that would limit the view to
all the mails from the author of the mail which was selected.  Since I
tend to remember mails by the name of the author which sent it.

,----[ $ grep -m1 -B3 .mutt/macros.conf ]-
| macro index A "<enter-command>unset wait_key<enter><pipe-message>\
| ~/bin/mutt_address.sh ~/temp/mutt_source.txt<enter><enter-command>\
| set wait_key<enter><enter-command>source ~/temp/mutt_source.txt<enter>" 
"limit message view by selected author"
`----

And mutt_address.sh looks like this:

#!/bin/sh

FORM=`which formail`
ARGS="`cat`"

# The sed statement will cut out only the relevant part from
# the e-mail address between <> (e.g. for "Foo" <foo.bar@xxxxxxxxxx> it 
# will only print foo\.bar@foobar\.xyz) and will also translate
# allowed characters like "." or "+" by escaping them
OUTPUT=`echo "${ARGS}"|"${FORM}" -tzx "From:" | sed 
's/.*<//;s/>//;s/\./\\\\\\\\&/g;s/+/\\\\\\\\\\\\\\\\&/g'`  
if [ -n "$1" ]; then
    TEMP="$1"
    exec >"${TEMP}" || { echo "Could not output to $1, exiting..." &&  exit 1; }

    cat <<EOF
    push "<limit>~f \"${OUTPUT}\"<enter>"'
EOF
else
    echo "You must supply a filename in which to store the result!" && exit 2
fi

This is probably pretty ugly, especially the escaping was hard to
figure out. But so far, I have not had any problems.
