I want change "mail_max_userip_connections" to 30.It's default is 10.I have found in /etc/dovecot/conf.d/20-imap.conf this file.
And I uncomment mail_max_userip_connections and change to 30.Then I restart dovecot this service.But it's aloways show
QuoteMaximum number of connections from user+IP exceeded (mail_max_userip_connections=10)
In the mail.log.Could I can't change this?
