I also think graphing make it easier to visualize what actually happen 
with your email system instead of
looking at bunch of text & numbers.

I am  using following combination of following software to create my 
graph :
- nrpe
- nagios
- n2rrd
- cacti
- modified updatemailstats.pl ( available from 
http://taz.net.au/postfix/mrtg/)

How I set it up :
- Nagios does monitoring and at the same time it collect performance 
data. So basically it combine 2 jobs into one : monitoring & reporting.
- n2rrd convert the performance data and convert it to rrd which can be 
used by cacti
- cacti provide web interface for graph management which allows you to 
easily zoom in and out of the graph, go to specific dates etc ...

Graph sample :

I have more graph but currently too lazy to upload.  You can modify 
updatemailstats.pl quite easily to suit sendmail.
Another useful reporting tool that I use is splunk ( splunk.com ) & 
mailwatch for mailscanner ( http://mailwatch.sourceforge.net/doku.php ) . 
The latest version of splunk allow you to search logs easily and you can 
create graph with ease.
