![在 Ubuntu 中,telnet 命令无法验证 sendmail](https://linux22.com/image/691535/%E5%9C%A8%20Ubuntu%20%E4%B8%AD%EF%BC%8Ctelnet%20%E5%91%BD%E4%BB%A4%E6%97%A0%E6%B3%95%E9%AA%8C%E8%AF%81%20sendmail.png)
我已经在 ubuntu 中安装了 sendmail,并尝试使用 telnet 命令进行身份验证。请参阅我的资料
产生用户名和密码
perl -MMIME::Base64 -e 'print encode_base64("username");'
perl -MMIME::Base64 -e 'print encode_base64("password");'
使用 telnet 命令测试

它没有登录,它显示身份验证失败错误,我100%确定用户名和密码是正确的。

我毫不怀疑用户名和密码生成,有人能指出这里出了什么问题吗?为什么没有得到身份验证。
