The most frequent error is ERR_CONNECTION_FAILURE_HOST2. Check that host1 localhost on port 143 is the right IMAP server to be contacted for your mailbox.

Fresh install on lxc debian 11 via this https://community.mailcow.email/d/1413-howto-install-mailcow-in-a-lxc-container-on-proxmox-64-13-for-home-usage. I cannot trace any logs (docker logs is full of trash, no usable info). On SoGo i can login to created mailbox, but no structure (inbox, sent, trash, etc). Telnet to port 143 is:
Trying ::1…
Connected to localhost.
Escape character is ‘^]’.
Connection closed by foreign host.
and nothing else. Thunderbird not get autodiscovery option. In fresh mailcow is nothing changed except add domain (for local delivery), created mailbox and sync job for this mailbox.
