perl newbie question

[Youn Gonzales]

Actually, the mrtg.cfg file provided by Julian calls sendmail.logs.pl. I
just changed my configuration to run mrtg for the mail statistics on an
hourly basis instead of every 5 minutes. I don't yet have confidence in the
information graphed by mrtg for the mail traffic, and as soon as I resolve
another issue that I am having with SpamAssassin I am going to look into it.

There is an Interval option for mrtg that I found on their web site
(http://people.ee.ethz.ch/~oetiker/webtools/mrtg/reference.html) which
controls part of how the information is segmented. Hopefully I will get more
time to play with it soon!
