nodemailer SMTP 服务器连接问题（错误：连接 ETIMEDOUT）但它适用于不在我的另一个系统

Question

Iam trying to send node mailer using webmail instead of GMail using smtp sever as follows..

// config connections
"nodemailer" : { 
         
         "host": "smtp.in-sciencelabs.com",
         "port": 587,
        "auth": {
        "user": "myuser.com", 
        "pass": "myp@ssword"
    }

// in nodemailer.js code iam importing the config details....

const transporter=
nodemailer.createTransport(smtpTransport((config["nodemailer"])));
     var mailOptions = {
               from: `${config["nodemailer"]["user"]}`,
               to: tomail,
               subject: subject ,
               text: data
             };
             transporter.verify(function(error, success) {
               if (error) {
                 console.log(error,"17");
               } else {
                 console.log("Server is ready to take our messages");
               }
             });

i tried to verify the connections so its shows an error like this

Answer 1

Have you looked at this answer .

It turns out that in order for Google to authorize a third party server to access your account via SMTP now, you have to enable “Less Secure Apps” on your gmail account, if you want to use username/password ( more info here ).

So you have two option:

• use OAuth

• make your account less secure

you also need to check your server firewall setting, This may be firewall problem, Problem can be solved by enabling TCP inbound and outbound in firewall settings on your server, if you are using digital ocean then you can find it in firewall settings in panel
