Internet Security Threat Report 2014

It's been a frustrating week for users of uk2.net whose email messages were bounced after one of the hosting firm's domains was blacklisted for spamming.

A Web site hosted on one of uk2.net's servers is selling software which could be used by spammers. Result: a blacklisting of the site spamsites.org and its IP address by relays.osirusoft.com.

uk2.net subscribes to the open relay list supplied by relays.osirusoft.com so from Wednesday this week it began automatically blocking email sent to many of its own legitimate users.

This is because relays.osirusoft.com provides a list of IP addresses to block - not domain names of offending site - so "innocent" uk2.net users whose sites share the same server/IP address for mail forwarding as the spam software sales site were also blocked.

The issue has affected a substantial minority of uk2.net's small business and home users, and many have expressed their frustration and anger over the problem in the company's forum. There are concerns that blocked emails from potential customers may be lost because of uk2.net's largely self-inflicted problems.

Promoting spamming software is contrary to uk2.net's usage policy but the company, which promotes itself as Britain's leading hosts, has been slow to act on the issue. Some members of the forum report they are once again receiving email, but others report continuing problems. ®
