POP3 Class help please

Hi, I am having trouble with a pop3 class that I use from the php class website written by Manuel Lemos. I have used this script in the past and its worked fine. I have now changed my webhost and I have the following problems : I can issue the fsokopen against the server and port (110) and get back what appears to be a valid pointer. When I try and read from the pointer I get eof condition immediately. i.e. no server greeting - I can manually telnet to port 110 and I can see the greeting, so I know the pop server is responding OK. I have tried the set_socket_blocking($fp,-1) and then tried retrying 5000 times - still nothing returned from fgets. BTW when I try against my old host (I still have an account there) it works perfectly - any ideas anyone? Can my host be blocking requests from http on their pop3 server? Thanks Jamie > ************
