maybe add a 'translation' of your log. There are hundreds of different
formats. I should post the template again that we are using for our
messages. But ask Wayne, our cvtwin maintainer, how hard it can be to
make sense of some of these logs. Portsentry is not bad (IMHO). But
still, think about the poor abuse desk guy and give them some hints ;-)

(e.g. say 
Target IP Address:
Source IP Address:
Targetport: 80
Time: Jan 13th 21:54:56 (UTC)

one note about time: spell out the month (something I have to fix in our
notices I think). Different countries use different conventions...

e.g. 01/02/03 could be: Jan 2nd 2003, Feb. 3rd 2001, Feb. 1st. 2003

I think the three letter English abbreviation for the month will work

And one more: Keep it brief. A couple lines of logs (10 maybe.. not
100), and no whois info or things that are 'obvious'. The strategic use
of the words 'Please' and 'Thank you' can help as well.
