Mailu: "Authentication rate limit from one source exceeded"

[chrisch-hh]

I'm checking ~10 mailboxes via IMAP with Thunderbird. On some mailboxes Thunderbird complains about a failed login. In the log of the mailu_front container I'm getting:

2018/10/25 10:06:04 [info] 8#8: *4503 client login failed: "Authentication rate limit from one source exceeded" while in http auth state, client: 80.xxx.xxx.xxx, server: 0.0.0.0:993, login: "[email protected]"

But I'm not sure from which component this error come from? dovecot?

I've tried mail_max_userip_connections = 50 in overrides/dovecot.conf but that doesn't solve the problem.

If you're using the latest version, you can change the rate limit in your .env file:

Thank you, I've missed this setting in the .env file. Seems to work.

i have this same problem. could someone tell me... is there a way to change this with the system running, or should I stop the container, change the ENV file, and then restart the container? or should i do a down command and start over from the beginning? ive never had to change an env variable on a container before.

You need to change variable and them start the container again u can even use the same command, because docker-compose will detect the changes and change container variables.
