[exim] graphs? stats?

Hello all,

Is there something that will make pretty graphs for non smtp-speak
people to see and understand for exim?

I see the latest mailgraph says it has exim support, but

$ /usr/local/sbin/mailgraph.pl -v --logfile /var/log/exim/mainlog -c

everyline just comes up with this:

WARNING: line not in syslog format:

Thanks in advance..
