OT NHS Firewall

Hi, Apologies for OT but is anyone on the list behind the UK NHS firewall? Nick are you there. Since the wall was relaunched the other day have been unable to pull down pop3 mail from outside. If anyone has any suggestions _please_ would they mail me at francesco.scaglioni@millbrook.cornwall.nhs.uk with any suggestions as to what has been altered so that I can ty and find a workaround. TIA Francesco
