Gmail阻止通过SMTP发送电子邮件？[副本]

Question

我尝试从这个问题设置msmtp服务器PHP Ubuntu使用gmail表单发送电子邮件localhost。所以我设置了默认（帐户）从：

/etc/MSMTPC：

defaults
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
account default
host smtp.gmail.com
port 587
auth on
user [e-mail]
password PASSWORD #not real password
from [e-mail]
logfile /var/log/msmtp.log

现在，当我尝试发送测试电子邮件（以root用户身份执行）时：

echo -e "Subject: Test Mail\r\n\r\nThis is my first test email." | msmtp --debug --from=default -t [e-mail]

给出：

loaded system configuration file /etc/msmtprc
ignoring user configuration file /root/.msmtprc: No such file or directory
falling back to default account

您可能需要在您的google帐户中启用不太安全的应用程序，以允许使用smtphttps://support.google.com/accounts/answer/6010255?hl=en

如果您使用双因素身份验证，您将需要生成应用程序特定的密码https://support.google.com/accounts/answer/185833?hl=en
