我有默认的 Postfix 安装，并且我希望能够[email protected]通过 Google 发送电子邮件。
我已经成功使用在 Ubuntu 12 和 14 上托管的网站很长时间了。
现在，当我尝试在 Ubuntu 16.4 中使用不同的设置（端口、SSL/TLS 等）将此电子邮件添加到 gmail 中时，我看到以下几行/var/log/mail.log：
Jul 8 21:19:35 host postfix/smtpd[15433]: connect from mail-lj1-f180.google.com[209.85.208.180]
Jul 8 21:19:37 host postfix/smtpd[15433]: lost connection after EHLO from mail-lj1-f180.google.com[209.85.208.180]
