So thanks Kyle you're right.

I've tried both the copiousoutput solution (mutt will wait for the
user to press a key while displaying an empty pager until the user
will press the exit key, mutt will delete the temporary file and the
browser won't be able to display it anymore), and this (somehow
circonvoluted, but more closed to what I want since I don't want to
change the usual mailcap behaviour) scripting solution.

Now I have in my mailcap:
text/html; ~/bin/web-browse %s

and in ~/bin/web-browse:

#! /bin/bash
file=$1

# textual session
if [ -z "display" ]; then
    links $file
    exit $?
fi

# graphical session
# if this script is run by mutt (the parent process is mutt)
if  ps -u $USER -o pid,command | grep -q "$PPID *mutt"; then
    tmp_file=~/tmp/mutt-$$-$(date +%s)
    mv $file $tmp_file
    file=$tmp_file
fi

if ps -u $USER -o command | grep -q "sawfish"; then
    sawfish-client -q -e "(select-workspace web-workspace-num)"
    epiphany --new-tab $file
else
    epiphany --new-tab $file
fi

In this way the script will mv the HTML file in a temporary file
with a unique name and exit, while epiphany will continue to see the
file (mutt will try to delete the original file which doesn't exist
anymore, but it seems without complaining).

The temporary file will be then automatically cleaned by a periodic
cron script.

Cheers
