是否可以使用nodemailer创建一个唯一的帐户，即使共享相同的进程？

const nodemailer = require('nodemailer');

// 创建唯一帐户1
const account1Transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  port: 587,
  secure: false,
  auth: {
    user: 'account1@example.com',
    pass: 'password1'
  }
});

// 创建唯一帐户2
const account2Transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  port: 587,
  secure: false,
  auth: {
    user: 'account2@example.com',
    pass: 'password2'
  }
});

// 使用唯一帐户1发送邮件
const mailOptions1 = {
  from: 'account1@example.com',
  to: 'recipient@example.com',
  subject: 'Hello from Account 1',
  text: 'This is a message from Account 1'
};

account1Transporter.sendMail(mailOptions1, (error, info) => {
  if (error) {
    console.log('Error:', error);
  } else {
    console.log('Email sent:', info.response);
  }
});

// 使用唯一帐户2发送邮件
const mailOptions2 = {
  from: 'account2@example.com',
  to: 'recipient@example.com',
  subject: 'Hello from Account 2',
  text: 'This is a message from Account 2'
};

account2Transporter.sendMail(mailOptions2, (error, info) => {
  if (error) {
    console.log('Error:', error);
  } else {
    console.log('Email sent:', info.response);
  }
});
