Surfeit of Security?

I wonder if anyone else is suffering a rash of returned/refused mail messages from cambourne.comm.coll.cornwall.sch.uk because I have now had in excess of 50 messages saying delivery of (an unknown) e-mail has been refused because of its nature! I think that includes the request to them to stop sending the refusal messages! I guess that's the ultimate in anti-bullying, anti-spamming, anti-communicative e-mail filters. I can't find a 'phone number to ring them, either. Anyone able to help? -- Best wishes, Derek Harding derek@lagham.zetnet.co.uk
