While Ofcom regulates snail mail it does not regulate email system provision..
This means that if you have a dispute with your provider you have no ombudsman protection and Ofcom claim they have no authority to investigate email disputes. As most ISPs treat their Email service as a free addon it is difficult to sue them. There is also no mechanism to compel them to fix problems or compensate the user. For example the BT Yahoo Email system appears to have been affected by the recent massive Yahoo hack but BT, despite frequent requests, have not confirmed this. The poor security and implementation of BT Yahoo mail has meant the frequent non delivery of emails and BT are reluctant or incapable of fixing this issue. The UK Government should compel Ofcom to recognise that Email is a means of communication that is vital to UK economy and that needs regulation. This problem is exacerbated by the fact the IT industry does not recognise the problem because they are shielded by their in-house systems.
