我想从我的Ubuntu服务器的命令行发送电子邮件。 所以我开始configurationpostfix到我的本地机器而不是在服务器上。 所以基本上这些是我遵循的步骤：
sudo apt-get install postfix mailutils libsasl2-2 ca-certificates libsasl2-modules sudo vim /etc/postfix/main.cf
将以下行添加到文件中：
relayhost = [smtp.gmail.com]:587 smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtp_tls_CAfile = /etc/postfix/cacert.pem smtp_use_tls = yes
sudo vim /etc/postfix/sasl_passwd
在文件[smtp.gmail.com]:587 [email protected]:PASSWORD添加了这一行
权限和更新后缀configuration文件。
sudo chmod 400 /etc/postfix/sasl_passwd sudo postmap /etc/postfix/sasl_passwd
重新加载POSTFIX： sudo /etc/init.d/postfix reload
然后在我的terminal上运行这个命令：
echo "Test mail from postfix" | mail -s "Test Postfix" [email protected]
但没有收到邮件。 所以我检查了日志文件，这是我发现它的下面的堆栈跟踪：
