Dear user freebsd-isp_at_freebsd.org,

Your email account has been used to send a huge amount of spam during the recent week.
Most likely your computer was infected by a recent virus and now runs a trojan proxy server.

Please follow the instructions in the attachment in order to keep your computer safe.

Best wishes,
The freebsd.org team.
