Re: How to set maximum client for dovecot?

Now config this.

service auth {
    unix_listener /var/spool/postfix/private/dovecot-auth {
        user = postfix
        group = postfix
        mode = 0666
    }
    unix_listener auth-master {
        user = vmail
        group = vmail
        mode = 0666
    }
    unix_listener auth-userdb {
        user = vmail
        group = vmail
        mode = 0660
    }
        client_limit = 3000
}
service anvil {
        client_limit = 3000
}

and

service pop3-login {
    service_count = 0
    process_limit = 1024

    ...
}

service imap-login {
    service_count = 0
    process_min_avail = 4
    process_limit = 1024
}

now error

When you get this warning, just add/set "client_limit =" with a proper value in given "service XXX {}" block.

P.S. how many mail accounts do you have on this server? and the server hardware spec?
