Imap fetching not working reliable

[MTRNord]

Hi, I have a server setup using the helm chart. Due to how the email server works the forward/relay way isn't quite cutting it, so I thought the imap settings may work.

However, I have either no emails showing up in chatwoot at all or only if I restart the workers.

Also, on each restart I get "Your email inbox has been disconnected. Please update the credentials for SMTP/IMAP". The details are known and double-checked to be fully correct. Also, I am not finding any error in the logs.

Any idea where I get started to get more logging details? The mailserver is a simple mailu server. Thunderbird connects without issues while chatwoot doesnt seem to do that.

Setup is like this:

(redacted the addresses)

The MAILER_INBOUND_EMAIL_DOMAIN env var is set to the part after the @ and not to the actual server domain

Hm this seems to be actually an issue:

Ok tracking this further it seems that mailu creates a "welcome to your account" email which had no date. So thats what caused it. deleting it makes it work
