我想知道是否有一种方法可以加快在 gmail 上使用 Nodemailer 发送电子邮件的速度。
我使用了标准的 nodemailer 文档，代码运行良好。我的问题是电子邮件和附件（使用用户输入的 pdfmake 创建）在大约 7-10 分钟后发送。有没有办法加快这个速度？这对用户体验真的很有帮助。
我应该提到需要 nodemailer 的函数是从应用程序调用的，并且是一个 Firebase 云函数。
以下是我的 firebase 云函数的代码：
exports.createCNDA = functions.https.onCall((data, context) => {
// Authentication / user information is automatically added to the request.
const uid = context.auth.uid;
const email = context.auth.token.email
const token = data.itemId;
admin.database().ref('users').child(`${uid}`).child('IA').child(`${token}`)
.child('Project').once('value').then(function(snapshot) {
const Project = snapshot.val();
