Re: My email address no longer exists some of the time!
To be honest the problems with the VM email system will probably never be fixed. There are many posts on this forum which highlight the failings, of which there are many, of the current VM email offering.
VM have recently started suggesting that VM email is an "added value" and free service (although their Terms and Conditions do not seem to support this stance as yet), and as such is unsupported is a warning sign in itself. (VM's current Fair Usage Policy seems to contradict this as it states:
3.4. Users are expected and required to review email messages in their primary Virgin Media mailbox provided as part of the services or the preferred email address registered with Virgin Media on a regular basis. This is to enable us to advise you of any significant issues that may affect your use of the services. We recommend that you check your primary Virgin Media mailbox or preferred email address at least every 3 days. We normally notify customers of AUP-related issues prior to suspension/disconnection of services and it is important that you read these emails.
