squircle's questions

After every email sent through my mail server, postfix/anvil appends something like the following:

Nov  9 15:09:11 keutenberg postfix/anvil[30006]: statistics: max connection rate 1/60s for (smtp:103.28.42.75) at Nov  9 15:02:42
Nov  9 15:09:11 keutenberg postfix/anvil[30006]: statistics: max connection count 1 for (smtp:103.28.42.75) at Nov  9 15:02:42
Nov  9 15:09:11 keutenberg postfix/anvil[30006]: statistics: max message rate 1/60s for (smtp:103.28.42.75) at Nov  9 15:02:43
Nov  9 15:09:11 keutenberg postfix/anvil[30006]: statistics: max cache size 1 at Nov  9 15:02:42

I understand why these messages are being logged (I set up the restrictions), but I can't find any way to change anvil's log level (i.e. to suppress these informational messages from mail.log). Is there a setting I can use in my main.cf to disable these statistical messages? I'd rather stop them at the source than suppress them through a syslog setting.

I have an SSL domain that runs nginx, and I want to be able to access my munin graphs/stats on that domain. So, in the domain's server block, I added this:

    location = /munin/ {
            alias /var/cache/munin/www/;
    }

Theoretically, I should be able to go to http://example.com/munin and be shown /var/cache/munin/www/index.html. However, I get a 500 error, and this message in error.log:

2011/08/26 15:21:25 [error] 19089#0: *31218 rewrite or internal redirection cycle while internal redirect to "/index.html", client: 1.2.3.4, server: domain.com, request: "GET /munin/ HTTP/1.1", host: "domain.com"

I've tried a bunch of different things, but nothing seems to work. I'd be really grateful if somebody could shed some light on this situation, and maybe come up with a solution. Thanks! :)

Here is the full configuration for the domain, if it helps:

server {

        listen 443 default ssl; ## listen for ipv6
        ssl_certificate         somewhere;
        ssl_certificate_key     somewhere;

        root /srv/www/domain.com/wwwroot;
        index index.html index.htm index.php;
        access_log /srv/www/domain.com/logs/access.log combined;
        error_log /srv/www/domain.com/logs/error.log;

        server_name example.com;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to index.html
                try_files $uri $uri/ /index.html;
        }

        error_page 404 /404.html;
        error_page 403 /403.html;

        # redirect server error pages to the static page /50x.html

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
                root /usr/share/nginx/www;
        }

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

        location ~ \.php$ {
                fastcgi_param HTTPS on;
                include fastcgi_params;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one

        location ~ /\.ht {
                deny all;
        }

        location = /favicon.ico {
                log_not_found off;
                access_log off;
        }

        location = /robots.txt {
                allow all;
                log_not_found off;
                access_log off;
        }

        location = /munin/ {
                alias /var/cache/munin/www/;
        }
}

server {

        listen [::]:80; ## listen for ipv6
        server_name example.com;
        rewrite ^(.*) https://domain.com$1 permanent;
}

I have Dovecot version 1.2.9-1ubuntu6.3 installed on my server (using Maildir+), and I was reading an article on Outlook 2010 that says that Outlook will purge messages immediately if the server supports UIDPLUS.

From my Googling, all I can find is a bunch of outdated mailing list messages of people asking questions. Does Dovecot support UIDPLUS for Maildir+/Maildir? Can it be added as an extension or is there some other way of adding this functionality? Thanks!

My /var/log/mail.log gets constantly flooded with Dovecot connect/disconnect messages like this:

Mar 29 18:15:48 summit dovecot: IMAP([email protected]): Disconnected: Logged out bytes=63/2126          
Mar 29 18:15:50 summit dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=4.3.2.1, lip=1.2.3.4, TLS

These are repeated ad infinitum (to the tune of 11MB of logs per day), and they're obscuring the more important authentication failures and Postfix deliveries/receptions. I've checked Dovecot's wiki page for logging, but no option there stops these messages. Is there any configuration variable I can set within dovecot.conf to stop these messages being sent to mail.log?

Clarification: I still want Dovecot to log to mail.log; I just don't want it logging these frivolous connect/disconnect messages.
