The value that you are storing in the RRD is a number that represents a '5
minute average expressed as units per second' which means that you need to
multiply the stored value by 300 (secs) in order to display something that
makes sense.

Using your example - 

   rrdtool graph spam-day.png --start -86400 \
            DEF:rss=spam.rrd:RSS:AVERAGE \
            DEF:dul=spam.rrd:DUL:AVERAGE \
            DEF:spews=spam.rrd:SPEWS:AVERAGE \
            DEF:spamhaus=spam.rrd:SPAMHAUS:AVERAGE \
            DEF:socks=spam.rrd:SOCKS:AVERAGE \
            DEF:sendmail_misc=spam.rrd:SENDMAIL_MISC:AVERAGE \
new>        CDEF:5minrss=rss,300,* \

new>        CDEF:5minsendmail=sendmail,300,* \
new>        LINE2:5minrss#FF0000:"Legend for rss"\
new>        LINE2:5mindul#FF0000:"Legend for dul"\
new>        ...etc
