Beautifying Logwatch for mail servers

A couple of tips I come up customizing the Logwatch setup of a couple of mail servers at work.
First off, make a copu of the file:

/usr/share/logwatch/default.conf/services/sendmail.conf

then fire up your text editor, and uncomment the line:

$Sendmail_PrettyHost

So the information on the daily report email will be separated by tabs, really useful.
Also, if you have a somehow heavy duty mail server, take a minute to edit the values for provided with the 'Sendmail Threshold values', most of those are setup to report whit a very low threshold, so you end up getting a huge email report everyday.
