我正在创建一个脚本来测试HELO的电子邮件..
直接在telnet控制台中,命令运行正常,但在脚本中,我无法获得输出.
在bash中:
$ telnet alt1.aspmx.l.google.com 25
HELO verify-email.org
MAIL FROM: <check@verify-email.org>
RCPT TO: <test@gmail.com>
quit
结果是:
root@san [~]# telnet alt1.aspmx.l.google.com 25
Trying 2a00:1450:4010:c09::1a...
Connected to alt1.aspmx.l.google.com.
Escape character is '^]'.
