使用gmail端口587的openssl客户端SMTP，< crlf>后的无响应（250 OK）。< crlf> [英] openssl client SMTP with gmail port 587, no response (250 OK) from after <crlf>.<crlf>

问题描述

我一直试图使用openssl与smtp.gmail.com端口587或465建立连接：
openssl s_client -host smtp.gmail.com -port 587 -starttls smtp

以及认证，邮件发送，rcpt和数据都是成功的。但我的问题是，在我写之后。在新行中，服务器没有250 OK响应。

这里是过程：

解决方案

也许在命令行中添加'-crlf'选项：

  openssl s_client -host smtp.gmail.com -port 587 -starttls smtp -crlf 
  

I've been trying to use openssl to establish a connection with smtp.gmail.com port 587 or 465 with: openssl s_client -host smtp.gmail.com -port 587 -starttls smtp

and the authentication, mail from, rcpt to, and data were all successful. but my problem is, after i write . in a new line, no 250 OK response from the server.

here is the process:

Maybe add the '-crlf' option to the comand line :

openssl s_client -host smtp.gmail.com -port 587 -starttls smtp -crlf
