Mailing list cleanup

[aos101]

As part of today's maintenance on our mailing list, we've removed a number of subscribers whose addresses have been bouncing back our email. We've removed a number of addresses which returned bounces saying "invalid user" or similar (in response to our "Traffic Management Profile Change" mailing on March 15th), and also removed any addresses whose domains do not resolve (so it is impossible to email them). We removed any addresses whose domains do not resolve an MX, A or CNAME DNS record.

Hopefully we haven't removed any currently active addresses. If we have it would be because the address temporarily had problems when we received the bounce message or the domain wasn't resolving the necessary DNS records for email to be delivered.

We've had to remove some addresses because some people forget or don't bother to remove themselves from our mailing list when their email address is shut down (e.g. when they move ISP). We don't like using resources to email non-existent accounts, so please if you are moving ISP/shutting down an email address and no longer want to be on our mailing list, use our mailing list page to unsubscribe.
