Vb & pop3

Hi all,
I'm trying to get my emails through winsock control. My account is in gmail server i.e. pop.gmail.com. I also know its pop port - 995. Socket is connecting the server fine but the server not throwing any initial greeting, neither +OK nor -Err. But the pop server for mail.com sending me the response immediately as soon as I connect. Is this for ssl security of gmail.com, rediffmail.com or yahoo.com or what? Do I need to send any certificate to the server in advance after I get connected? The code -

Button Code --------------------------
WS.protocol = sckTCPProtocol
WS.RemoteHost = "pop.gmail.com"
WS.RemotePort = 995
WS.Connect
DataArrival Code ----------------------
Dim sData As String
WS.GetData sData
Debug.Print sData

I'm not being able to send my UID/PWD because no greeting is sent through DataArrival.

But in case of mail.com the immediate window shows the following text -
(pop1.mail.com/110 here)

+OK OBMail POP3 server ready <[email protected]>

My local IIS POP3 also responding well with -

+OK Microsoft Windows POP3 Service Version 1.0 <7052984@pradip-w2k3s> ready.

Please help
