This ought to work; I use something very similar:
To every transport listed in /etc/smail/transports, add
"shadow=keepit".  That is, one of the transports might look like:

local:  driver=appendfile, from, local, inet, return_path,
	unix_from_hack, shadow=keepit;
        append_as_user, check_user, file=/var/spool/mail/${lc:strip:user},
        group=mail, mode=0660, notify_comsat, suffix="\n"

Then, add this to the end:
keepit:	driver=pipe, from, local, inet, return_path, unix_from_hack;
        cmd="/usr/local/bin/keepitmail 0", umask=0077, user=root,
	group=mail, parent_env, -ignore_status

Now, make /usr/local/bin/keepitmail the following script:
#!/bin/sh
LOGDIR="/var/log/mailstorage";
MAILLOGPREFIX="mailstorage";
STOREFILE="$MAILLOGPREFIX.`date +%Y%m%d`";
cat >> $LOGDIR/$STOREFILE
echo >> $LOGDIR/$STOREFILE
exit $1;

Note that this only logs mail that is successfully passed on to the
outside world or delivered locally.  You could add "error=errorkeepitmail"
to each transport and then add:
errorkeepit:	driver=pipe, from, local, inet, return_path, unix_from_hack;
        cmd="/usr/local/bin/keepitmail 1", umask=0077, user=root,
	group=mail, parent_env, -ignore_status

To the end to log mail with errors as well.  However, this might make
mail bounced for errors not have the correct error message.
