Googlespell and mod_security?

Hi,

I am wondering if anyone uses Roundcube with mod_security on Apache? I got some 406's from logwatch this morning.

Requests with error response codes 406 Not Acceptable snip< /?_task=mail&_action=spell〈=en: 3 Time(s)

The previous day while writing some emails I ran the spell checker to get an error message indicating a problem with the server. The relating error logs point to IP's in South East Asia.

Mod_security seems to be doing its job but I wondering if anyone with more experience that myself has noticed this as well? And if it's a problem? Could just be a problem with the Google servers?

All seems fine today. Spell check runs fine.

Regards,

Robert.
