通过Windows命令行连接到gmail pop服务器

Question

I'm using command line on Windows 7 or Windows Command Processor. I'm trying to connect to gmail pop server (pop.gmail.com) on port 995 because that is what I have seen on other Web sites. I want at least to get an "+OK Hello there" message. This is the command I wrote:

telnet pop.gmail.com 995

I'm not getting any answer. What am I doing wrong?

Answer 1

Port 995 is for SSL connection. You cannot do it with telnet. You could probably try OpenSSL and to test it that way.

openssl s_client -connect pop.gmail.com:995 -quiet

More info on OpenSSL for Windows is here: OpenSSL for Windows

I have just tested with openssl command I gave you above. It works like a charm:

user@localhost$ openssl s_client -connect pop.gmail.com:995 -quiet

verify return:0
