SKYMARKET LTD CO-LOCATED USAGE POLICY (AUP)

1. You must not use your Internet connection for any illegal purpose.
You should be aware that some material is illegal to possess or transmit. You should also note that unauthorised access to computer systems can be an offence; although many machines connected to the Internet are placed there so that you may access them, it does not follow that you may access any computer you come across.

2. Your traffic over the Internet may traverse other networks, or use other services, which are not owned or operated by Skymarket Ltd. You must abide by the AUPs and other terms and conditions imposed by the operators of those networks and services.

3. Whilst connected to the Internet your system must conform to all relevant IETF standards. The IETF (Internet Engineering Task Force) standards are a subset of the RFC (Request for Comments) collection and can be requested by sending an email to ietf@skymarket.co.uk at any time.

4. You must not send packets onto the Internet which have forged addresses or which are deliberately constructed so as to adversely affect remote machines.

5. Your machine or network must not be configured in such a way that others can exploit it to disrupt the Internet.
This includes but is not limited to ensuring that your network cannot be exploited as a "smurf amplifier". Note that traffic from simple dialup accounts is already filtered by Skymarket Ltd to prevent this. For more information about "smurf" attacks see: http://users.quadrunner.com/chuegen/smurf.cgi and http://netscan.org

6. You may not run "scanning" software which accesses remote machines or networks, except with the explicit permission of those remote machines or networks.

7. You must ensure that you do not further the sending of unsolicited bulk email or any other form of email or Usenet "abuse". This applies to both material which originates on your system and also third party material which passes through it.

8. You must not run an "open mail relay", viz a machine which accepts mail from unauthorised or unknown senders and forwards it onward to a destination outside of your machine or network. If your machine does relay mail, on an authorized basis, then it must record its passing through your system by means of an appropriate "received" line.
Users of "WinGate" should take special note that this software is capable of providing a wide range of relaying services. Default configurations can cause a problem, so that special care must be taken to configure it to prevent unauthorised use. More information is currently available at: http://www.cert.org/vul_notes/VN-98.03.WinGate.html
As an exception to the ban on relaying, you may run an "anonymous" relay service provided that you monitor it in such a way as to detect unauthorised or excessive use. However, you may not relay traffic from such an anonymous system via Skymarket Ltd’s servers, ie: you can only pass email from such a system to Skymarket Ltd where this is the correct destination for final delivery.

9. All customers are required to accept email addressed to postmaster@yourdomain Customers will be deemed to have read any and all such email. Skymarket Ltd may take action on the basis of this assumption.

10. Skymarket Ltd, at its discretion, may run manual or automatic systems to determine compliance with this AUP (eg scanning for open mail relays or smurf amplifiers). Customers are deemed to have granted permission for this limited intrusion onto their networks or machines.
This includes but is not limited to ensuring that your network cannot be exploited as a "smurf amplifier".

13. Any decision Skymarket Ltd makes in relation to its services will be final on all matters
