Hi guys, 

I am a beginner of learning erlang. My problem is whenever I call
gen_tcp:recv, I got {error, closed} all the time. 

The procedure is as following: 

1> Opts = [list, {packet, 0}, {active, false}, {reuseaddr, true}]. 
2> {ok, Sock} = gen_tcp:connect("pop.gmail.com", 995, Opts). 
3> Res = gen_tcp:recv(Sock, 0). 
{error, closed} 

Is the problem about my code or about the pop server? 

Thanks so much for your reply.
