try this handy little perl script i wrote.  It calcualtes what the date was seven days ago, reads in the mail file specified on the command line.  searches for the first message from 7 days ago and writes from there on back into the mail box.  PLEASE BACK UP YOUR MAILBOX UNTIL YOU ARE SURE IT IS WORKING CORRECTLY, THIS WILL OVERWRITE THE MAIL FILE.  for you case you would need to run it as root or oracle.  command line execution is

perl purgemb.pl oracle

could be any user ID and you could hard code it to oracle to eliminate the need for command line arguement.

$is_found = 0;
my($day, $month, $year, $wday)=(localtime(time() - (86400*7)))[3,4,5,6];
my @mabbr = qw( Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec );
my @wabbr = qw( Sun Mon Tue Wed Thu Fri Sat );
$year = $year+1900;
open MAIL_FILE, "</var/mail/$ARGV[0]" or die $!;
@mail_data=<MAIL_FILE>;
close(MAIL_FILE);
foreach $line (@mail_data)
{
        if ($is_found != 1 && $line =~ /^From .*$wabbr[$day].*$mabbr[$month].*$day .*$year.*$/)
        {
                #Matched First Message from 7 days ago
                open MAIL_FILE, ">/var/mail/$ARGV[0]" or die $!;
                $is_found = 1;
        }
        if ($is_found == 1)
        {
                print MAIL_FILE $line;
        }
}
close(MAIL_FILE);
