Yes.

Try this, if your /bin/sh understands the ${parameter#word} and
${parameter%word} syntax (it works fine for me with bash, but is
broken with my version of /bin/ash):
--------------- snip ---------------
#! /bin/sh
#lxmutt.sh called by lynx external for mailto:'s receives
#'mailto:address@hidden' as it's argument, chops off the
#'mailto:' and subject if present, and passes the address and subject
#to an email program (here, mutt).
MAIL_PRG=mutt

#Note: URL-escaped characters in mailto-URLs are NOT handled correctly.
#
URL="$1"
RECIPIENT="${URL#mailto:}";
STRIPPED_RECIPIENT="${RECIPIENT%%[?]subject=*}"
if [ "$STRIPPED_RECIPIENT" = "$RECIPIENT" ]; then

    $MAIL_PRG "$RECIPIENT"

else    # "$STRIPPED_RECIPIENT" != "$RECIPIENT"
    SUBJECT="${RECIPIENT#*[?]subject=}"

    $MAIL_PRG -s "$SUBJECT" "$STRIPPED_RECIPIENT"

fi

Not perfection, since %XX isn't unescaped and other xxx=yyy pairs
aren't handled.

Also it doesn't handle a subject given by
<A HREF="mailto:..."; TITLE=subject>.

None of that seems to apply for EXTERN.
