如何使用Java中的套接字验证SMTP服务器是否正常工作

Question

I want to check if the given SMTP server is working fine by just getting connection and send a hello message and then verify the response code. I don't want to test it by sending email to some address.

I am using java 1.6.

Please help

Answer 1

Create a socket Socket s = new Socket("addres_of_smtp_server", stmp_port);
and then check if the server is alive. Here is the same question in stackoverflow How to check status of an SMTP server from Java? . Hope it helps.
