E-Mails Sent to a HCI Data Mail Server

This includes e-mails sent to HCI Data's E-mail server for forwarding onto other servers.

HCI Data Ltd reserves the right to block any e-mail sent to HCI Data Ltd or its clients which may be unsolicited. We (HCI Data Ltd) further reserve the right to block any e-mail that may contain a virus. Furthermore, we may block all e-mail from a specific IP address that has been seen to be a source of unsolicited e-mail or viruses or is relaying such e-mails. The block will be released when we are satisfied that the source or relay has stopped sending such e-mail and is not likely to restart.

E-Mails Originating from HCI Data's Servers

These e-mails will be generated by HCI Data Ltd or one of its clients.

E-Mails from HCI Data Ltd (hcidata.com and hcidata.co.uk)

HCI Data Ltd does not send out unsolicited bulk e-mails - also known as spam. It only sends e-mails to clients, suppliers or those who have requested information from HCI Data Ltd.

Any unsolicited e-mails apparently from HCI Data Ltd are probably forgeries. These forgeries are known as Joe-Job. Joe-Job is jargon for a spam run forged to appear as though it came from an innocent party, who is then generally flooded by the bounces; or, the act of performing such a run. The original incident is described here. HCI Data has frequently been the victim of a Joe-Job forgery.

E-mail from Clients of HCI Data Ltd

HCI Data Ltd does not tolerate the sending of unsolicited bulk e-mail. Clients of HCI Data ("the client") who use HCI Data's servers must ensure that any mailing list conform to ALL the following standards when sending bulk e-mail:

• Every e-mail's "From" address must be owned by the client.
• Every e-mail's "From" address must accept e-mail from anyone on the mailing list.
• Every address in the mailing list must have been positively subscribed to the mailing list. That is, the person who uses an e-mail address must have requested to be added to a specific mailing list - e-mail addresses harvested from address books or other e-mails do not classify as "positive subscription"
• When a user positively subscribes to a mailing list, the client that uses the mailing list must be clearly identified before the user subscribes.
• Use of mailing lists supplied by other companies or organisations are expressly forbidden.
• Every e-mail must carry details on how to unsubscribe and the method of unsubscribing must be an e-mail address to send the unsubscribe request to or a web URL that accepts unsubscribe requests.
• Every unsubscribe request must be actioned within 3 working days of receipt.
• No message can contain avoidance techniques to get around any anti-spam software that the message may pass through before being delivered to the subscriber.

Should any of the above standards not be met, HCI Data Ltd reserve the right to remove the e-mail facility from the client without notice.
