[IMAP] Error fetching from mailbox XXXX: Connection not available
Hello dear people π
I am facing an issue when testing the IMAP email sync. I was able to configure the IMAP using the Lab option and UI settings, but I am now faced with the error in the title.
Here is the docker log:
(the rest will be in a message below because caracters count limit)
Any clue as to why this is happening and how I can fix it?
Thanks a lot.

Do you know what kind of mail server are you using? Is it a self hosted one? Would help a lot in reproducing the issue
Unfortunately not hosted, no. I could try with one if you'd like.
