Direct Reply broken

Description:

Hello Devs.

Direct reply via email was working at least until version 5.1.x. Now with 5.3.1 running I noticed it's broken again. Configuration is the same as with the working rocketchat version. It seems login to the IMAP Server (Dovecot) only works partially.

Nov 15 11:37:01 imap-login: Info: Login: user=<rocketchat>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=2536, TLS, session=<hDKw73/tHux/AAAB>
Nov 15 11:37:06 imap-login: Info: Disconnected: Connection closed (no auth attempts in 5 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, TLS: Connection closed, session=<e1D873/tHOx/AAAB>

As you can see, the second login attempt has the username missing.

Rocketchat Log looks like this:

{"level":50,"time":"2022-11-15T17:52:50.902Z","pid":4759,"hostname":"pages","name":"EmailInbox","err":{"type":"Error","message":"Timed out while authenticating with server","stack":"Error: Timed out while authenticating with server\n    at Timeout._onTimeout (/opt/rocketchat-5.3.1/programs/server/npm/node_modules/imap/lib/Connection.js:139:17)\n    at listOnTimeout (internal/timers.js:557:17)\n    at processTimers (internal/timers.js:500:7)","source":"timeout-auth"},"msg":"Timed out while authenticating with server"}
{"level":50,"time":"2022-11-15T17:52:50.907Z","pid":4759,"hostname":"pages","name":"EmailInbox","msg":"IMAP error: Timed out while authenticating with server"}

I'm here if you need any more infos.

Steps to reproduce:

1. Enable Direct Reply
2. Answer to an notifiaction email via email
3. Email is not processed by rocketchat

Expected behavior:

Email content goes to the rocketchat channel.

Actual behavior:

It doesn't.

Server Setup Information:

• Version of Rocket.Chat Server: 5.3.1
• Operating System: Linux
• Deployment Method: tar
• Number of Running Instances: 1
• DB Replicaset Oplog: yes
• NodeJS Version: 14.21.1
• MongoDB Version: 5.05

Reproduce the failure with Direct Reply enabled and inspect the EmailInbox error alongside programs/server/npm/node_modules/imap/lib/Connection.js around line 139. Compare the two Dovecot login attempts and verify that replying to a notification email is processed into the Rocket.Chat channel without an authentication timeout.
