Statistics of viruses caught by Frontfree Mail System yesterday

Gibe is still the first place, and MyDoom(here, it was called Worm.SCO.A) drastically dropped down.

beastie# bzcat maillog.0.bz2 | grep INFECT | awk ‘{print $8;}’ | sort | uniq -c | sort -rn
181 (Worm.Gibe.F),
86 (Worm.SCO.A),
2 (Worm.Dumaru.Y),
1 (Worm.Sobig.F),

Top virus receivers:

You see, because that I am splitted into delphij at frontfree.net and delphij.net, so I should get the second place, here:
beastie# bzcat maillog.0.bz2 | grep INFECT | awk ‘{print $11;}’ | sort | uniq -c | sort -rn
119 onefi@frontfree.net,
68 null@frontfree.net,
66 delphij@frontfree.net,
11 junsu@frontfree.net,
4 delphij@delphij.net,
2 webmaster@frontfree.net,
