  --- BEGIN ISSUE ---
  Maximum number of connections from user+IP exceeded 
  Hi, we have a problem... :-)
  We have changed the original value of "AUTH_RATELIMIT" to "AUTH_RATELIMIT=100/minute;6000/hour", but logs continue to say " Maximum number of connections from user+IP exceeded (mail_max_userip_connections=20)" while reading response from upstream..."
  We have made docker-compose dow and docker-compose up -d, but without result.
  How can we change the default limit set during the installation?
  Thanks in advance.
