TW Blueyonder Gets Tough On SPAM
By: MarkJ - 13 November, 2003 (9:15 AM)

The UK dialup and broadband ISP wing of cable operator Telewest, blueyonder, has issued a new announcement regarding stronger action against junk e-mail (SPAM). Measures will include the blocking of hosts that allow large quantities of junk through their servers:

We have in recent times seen a significant increase in the number of reports into our abuse team of spam, mostly consisting of open relay spam -- which is due to poorly configured customer PCs that are being used by spammers to send their spam.

Accordingly, we have decided to step up our measures to deal with the customers whose PCs that are generating the most reports.

From Wednesday 12th November 2003 we are enforcing SMTP blocking for hosts that are generating large volumes of spam. In short, the hosts generating the "top 100" reports of open relay spam on a daily basis will not be able to send mail via the blueyonder SMTP servers until they have closed that open relay. We are setting a threshold of 300 daily reports for qualification for the "top 100" list initially, but will be reviewing this on an ongoing basis.

We have been researching our findings over a couple of weeks and believe that most of the spam being sent from PCs on the blueyonder network is being generated by open relays , open proxies and specific Trojans that are acting as gateways for spammers.

What does this mean for our users?

- Initially, in excess of 300 daily reports into abuse@blueyonder.co.uk originating at a particular IP address will make a host eligible to be blocked

- Once the block is in operation a email will be sent to the primary mailbox for that user explaining what has been done and methods for the customer to check your systems for anything suspicious.

- A contact telephone number for assistance in removing the block once the user has resolved their issues that are resulting in the spam reports

All customers who are affected by the block will have full use of their email for sending via Webmail and POP3 and IMAP4 will not be infected.
