We are the email provider for the commercial brands affected. They are retail brands sending to their customers, in this case BT users. The block means they cannot send any emails, not even critical ones such as receipts, order updates, shipping information etc. As a result they now have many upset customers.
Given there is no information available about the cause of the block or what the brands themselves can do from their side, if anything, to resolve this it is critical we hear back from the Postmasters soon. As mentioned in the past where the BT Postmasters have been slow to respond moderators in this forum have kindly helped by raising this to the Postmasters.
