[mod-security-users] Help: How to configure modsecurity2 to allow webmail programs such as SquirrelMail, Roundcube?

[H.Kim <hk...@gm...>]

I have a VPS/Debian and have just installed modsecurity2. Everything seems
to work, but now I can not access the webmail programs installed on the
server. When trying to to that from the DirectAdmin control panel, following
error is logged:
[Sat Jan 26 21:52:34 2008] [error] [client IP_ADDRESS] ModSecurity: Warning.
Match of "rx ModSecurity" against "WEBSERVER_ERROR_LOG" required. [id
"960913"] [msg "Invalid request"] [severity "CRITICAL"] [hostname
"IP_ADDRESS"] [uri "/squirrelmail"] [unique_id "xxx"]

How do I correct this "false positive"?
