stopping "connect" attacks in apache

[Bob]

Every time my apache server slows down or has denial of service the access
log is full this

61.228.122.220 -  "CONNECT 66.196.97.250:25 HTTP/1.0" 200 7034 "-" "-"
61.228.122.220 -  "CONNECT 216.39.53.3:25 HTTP/1.0" 200 7034 "-" "-"
61.228.122.220 -  "CONNECT 216.39.53.1:25 HTTP/1.0" 200 7034 "-" "-"
61.228.122.220 -  "CONNECT 168.95.5.155:25 HTTP/1.0" 200 7034 "-" "-"
61.228.122.220 -  "CONNECT 168.95.5.157:25 HTTP/1.0" 200 7034 "-" "-"
61.228.122.220 -  "CONNECT 168.95.5.159:25 HTTP/1.0" 200 7034 "-" "-"


I think I can stop this by adding this to my httpd-config

SetEnvIf  THE_REQUEST CONNECT* drop
<Directory "/usr/local/www/data">
order allow,deny
allow from all
deny from env=drop
</Directory>


Am I on the correct solutions here?
