Every time I have posted to this list today I have also received an email from Randomail with this text that I have listed below. I have a bad feeling about this as it seems that somehow mail going into the list is being intercepted along the line. It's only to this list that it's happening does any body know anything about it? Sorry to posting directly to the latest but I can't seem to find an admin address.
