Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-isp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi All, This isn't strictly FreeBSD relates, but it is very ISP related... I've just checked through my morning security logs, and suprise, suprise our entire address space was scanned again lastnight for SMTP relays... Theres loads of firewall logs for SMTP connects to machines we don't allow SMTP to, and on the machines we do allow SMTP to - in the logs are loads of sendmail catches for 'Relaying Unavailable' (the message we send to people trying to relay)... My question is - I have the IP address these came from, they are a Spamming Company by the look of it, and to be honest I'm sick of this sort of thing... Is it worth me mailing the people? - Or should I just be grateful we weren't used as a relay and let them be? I'm just annoyed a company that obviously has set out to specialise in spam/electronic mailing lists doesn't even use it's own servers to send the damned stuff out... Annoyed...
