Problems with Email and other issues....

My Account Reference: [MOD EDIT: Personal details]

Hi, I contacted the VM customer help desk last Tuesday evening concerning an issue I'm experiencing with our Apple mobile devices. The mail app stopped receiving emails and returned the following error relating to online status: Temporarily blacklisted IP Address - try again later. I believe the supervisor on duty noted the issue for forward resolution but I have no record of that. It's now 2 days later and the problem is continuing. This morning I had a call with Apple to see if they could help and to get their opinion on the likely cause. We tried isolating the network by switching Wi-Fi off and on and uninstalling and reinstalling two internet accounts plus changing passwords via the VM website all without success. Mobile data is working okay. I should add that I had already rebooted the VM 5 Hub without any change. Despite the 'blacklisting' Apple felt there was an unlikely conflict with my IP address. Their conclusion is that the problem is a VM network issue and not an Apple one (maybe a result of Router upgrade?) as everything was working fine before. I'm really head scratching now for answers as although we are able to access the email accounts through the VM web page portal users will appreciate this is totally unacceptable for any length of time.

Please is anyone out there able to resolve this in quick time?

Best regards
