如果收件人电子邮件错误，则在Nodemailer中出错

Question

我正在使用Nodemailer SMTP发送电子邮件

如果电子邮件帐户有效/存在，它可以正常工作，但是不存在输入电子邮件地址时出现500错误的错误。

我知道它没有发送，因为电子邮件不存在，但需要处理错误

我也尝试过tls: {rejectUnauthorized: false},，但遇到同样的问题

我使用自定义SMTP而不使用Gmail SMTP

我的代码如下：

let transporter = nodemailer.createTransport({
                host: 'smtp.myhost.de',
                port: 587,
                auth: {
                  user: 'CUSTOM_SMTP_EMAIL', // generated ethereal user
                  pass: 'CUSTOM_SMTP_PASS' // generated ethereal password
                },
                secure:false,
                requireTLS: false,
                tls: {rejectUnauthorized: false},
                debug:true
              });



let info = await transporter.sendMail({
                from: sails.config.custom.appName+ SENDER_EMAIL, // sender address
                to: inputs.email, // list of receivers
                subject: "My email subject ", // Subject line
                text: "Verify Email Address "+inputs.email, // plain text body
                html: html // html body
              },function(err) {
                console.log('email sent');

                if (err){
                    console.log( 'err->>>>>>>>>>>>>', err);
                    return exits.success('error');

                } else {
                   console.log('success');
                   return exits.success('success');
                }
              });

由于500错误，我无法返回return exits.success('error');。

得到以下错误

如果没有将回调作为第二个参数传递给sendMail，它将返回一个可以等待的承诺：

let info = await transporter.sendMail({
    from: sails.config.custom.appName+ SENDER_EMAIL, // sender address
    to: inputs.email, // list of receivers
    subject: "My email subject ", // Subject line
    text: "Verify Email Address "+inputs.email, // plain text body
    html: html // html body
}).then(() => {
    console.log('success');
    return exits.success('success');
}).catch((err) => {
    console.log( 'err->>>>>>>>>>>>>', err);
    return exits.success('error');
});

console.log(info);
