I currently have a site using Nodemailer & Gmail that works fine in my local development environment - any email sends instantly to the desired address.
Sadly, in production, only the admin notifications are being sent and the user ones are taking a very long time to deliver or not delivering at all. Ones that have arrived successfully took around 1 hour. The receiving email for admin emails is of the same domain as the URL of the website which makes me consider whether it's a domain verification issue. Only external recipients seem to get the delay.
My code is as follows:
const nodemailer = require('nodemailer')
const gmailUser = process.env.GMAIL_USER
const gmailPass = process.env.GMAIL_PASS
const appTitle = process.env.APP_TITLE
const receivingEmail = process.env.MAIL_RECEIVE
const smtpTransporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 465,
secure: true,
auth: {
user: gmailUser,
pass: gmailPass
}
})
const emailConfirmation = (userEmail) => {
const userMailOptions = {
from: appTitle,
to: userEmail,
subject: `${appTitle} - User Confirmation`
text: 'User Confirmation'
}
const adminMailOptions = {
from: appTitle,
to: receivingEmail,
subject: `${appTitle} - Admin Confirmation`,
text: 'Admin Confirmation'
}
Promise.all([
smtpTransporter.sendMail(userMailOptions),
smtpTransporter.sendMail(adminMailOptions)
])
.then((res) => { return true })
.catch((err) => { console.log("Failed to send email confirmations: ", err); return false })
}
I then call the function in a POST handler as follows:
emailConfirmation(user.email)
Am I doing something wrong in my code, or is this likely to be some sort of domain verification error?
