First Cox blocks my e-mail forwarding from the 757 account because someone complained that email@example.com was in the "From" address. It tooks weeks of arguing with the helpdesk and the abuse desk to get it unblocked.
Then they reblock it by turning on their spam filters, which I had expressly asked that they not do. This caused me to have to set up encrypted mail on two sites and I have no option on a third.
This on top of the near-constant ARP storms and the period loss of carrier on the cable modem. How much do I pay for this?
