Fail2ban on dovecot: question on logs

According to Whois this IP address belongs to “Emanuel Hosting Ltd.” in the UK. If this is the hosting provider you are using, maybe they do some kind of health checks on services that are running. Or did you set up some kind of monitoring that does active checks?

I am not in UK and I have exactly the same thing, from the same IP address.

It is not clear to me what the fail2ban.filter INFO messages mean, whether it means this is blocked or not.

This is nothing super new, see Fail2ban is not blocking repeated attemtps on postfix and dovecot. There was a reply to this saying that some change was done, but reading the description, I fail to see the relationship with it.

So I would say, it still looks like “Fail2ban blocking postfix/dovecot login attempts has not been implemented yet.”. I guess it means one should use strong passwords i.e., randomly generated by your computer and stored in a password manager.
