Mail events are not triggered most of the time #889

Open LanXiaoChr opened 2 years ago

LanXiaoChr commented 2 years ago

When I receive a new email in my work email, the ‘mail’ event doesn't fire. It's the same when I use my private email. Sometimes, when I rerun the program it may work but most of the time it doesn't.

const Imap = require('imap')

let imap = new Imap({
    user: 'xxxxxx@xxx.com',
    password: 'xxxxxxxx',
    host: 'imap.xxxx.com',
    port: 993,
    tls: true
})

imap.once('ready', () => {
    imap.openBox('INBOX', true, (err, box) => {
        if (err) throw err
    })
})

imap.on('mail', (mail) => {
    console.log('new email: ' + mail)
})

imap.connect()

Log:
