Hi Timo - I saw this addition and it sounds very useful in our enviroment. Can the plugin be enabled for specific users? Or is is a system-wide only plugin? -- Roger J.

I use the syslog facility for logging purposes. I was wondering if there is a way to redirect all logs to mail.* For example, there are user.* messages.. can I change all of them to mail.* ? thanks. -- giannis.

[Dovecot] MRTG

Quite a long ago someone proposed a patch to allow the Dovecot data to be collected and displayed via MRTG. Is there anyone who is actually using MRTG to analyze Dovecot traffic?

[Dovecot] Message size incorrect?
by Tristan Woudenberg - Prism Mail Solutions 20 Jan '07

20 Jan '07

Hi there, I recently installed a plugin for SquirelMail (php imap client, squirrelmail.org) which adds up message sizes per folder to display a nice total size of each subscribed folder. After consulting the plugin maintainers at SquirrelMail in this thread: http://thread.gmane.org/gmane.mail.squirrelmail.plugins/12468/focus=12468 There is quite a discrepancy in the rfc822.size reported by Dovecot and the actual space it takes up on my harddisk. I know there could be some overhead here from all the dovecot* and subscription list files in my imap folders, but like I stated in my email to the SquirrelMail plugin mailing list, about 1mb for a 4.3mb maildir mailbox might be a but much. Could this be like Tomas Kuliavas wrote: "Maybe those message have some data that does not belong to message or their formating breaks dovecot's message parsing functions."? I'm using Dovecot-1.0.rc15, sorry if this has been fixed between this release and the current. Kindest regards, Tristan -- Prism Mail Solutions Deployment, customization and hosting http://prism.nl

I hope this helps. > If there is anything else I can provide to shed more light, let me know. login_processes_count = 32 This means that Dovecot always keeps extra 32 login processes that don't do anything else than wait for new connections. That's not at least helping :) Anyway, I'd like to get lsof of an imap-login process that is doing SSL proxying. Unfortunately I don't think there's any simple way to know what processes are doing that and what aren't. Setting login_process_count=1 at least makes it more likely that you'll hit the right process. If trussing the process shows that it's writing some garbage to file descriptor 1, it's probably proxying SSL..
