[Dovecot] Quota Limits Newbie Question
by Craig Carriere 23 May '07

23 May '07

I have Dovecot 1.0 running on a SLES 10 mail server using postfix 2.2 and amvisd-maia. The mailboxes are stored in Maildir format with all the domains and users stored in a mySQL database. I would like to implement quotas for the system and have looked at the VDA patch for postfix and/or quotas within Dovecot. Any advantages to either? From what I can see from a couple of searches, Dovecot does not appear to respond either to the sender or recipient when they are over quota while one can set-up postfix-vda to do so which would be of value. Thank you for the time and input.

[Dovecot] need some help please

We currently had dovecote 99 running and ran into some issues with it, mainly our pop3 sessions timeout and were slow. I upgraded to the latest version and im serving imap with pop3 using pam. Heres my pam file: [root@pop etc]# cat /etc/pam.d/dovecot #%PAM-1.0 auth required pam_unix.so nullok account required pam_unix.so The problem I'm having is I can authenticate to imap, but it's very slow, however pop3 doesn't work at all.

[Dovecot] shared folders
by David Obando 23 May '07

23 May '07

Dear all, I would like to use shared folders but I'm not quite sure whether Dovecot supports it the way I want it: -user A should be able to share a folder with users B, C, D -B, C and D should have read-access to this folder Did anyone implement shared folders like this?

[Dovecot] Quota warning message ala courier
by Ralf Hildebrandt 23 May '07

23 May '07

I have to face it, my users are retards: * either they're using crap MUAs which will not display their quota to them * or they're using POP with "leave mail on server" and will never notice their quota, unless it's too late * and once their quota is exceeded, their mails will bounce -- they'll never notice that, though. Thus I need a feature in dovecot that will tell them via email: Level1: "You ALMOST exceeded your quota, you're at 90% now" Level2: "You're very close to exceededin your quota, you're at 95% now" Level3: "Would you please clean up now? You're at 99% now" -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) plonk(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de "Hardware: the parts of a computer that can be kicked." -- Jeff Pesis

[Dovecot] Quota handling - opportunity for new Feature?
by Charles Marcus 23 May '07

23 May '07

This initial proposal for a Feature Request is the result of my desire to implement quotas, but not have the attendant headaches that inevitably accompany its implementation. Ralf Hildebrandt wrote: > I have to face it, my users are retards: Is there any other kind of user? ;) <snip> > Thus I need a feature in dovecot that will tell them via email: > > Level1: "You ALMOST exceeded your quota, you're at 90% now" > Level2: "You're very close to exceededin your quota, you're at 95% > now" > Level3: "Would you please clean up now? You're at 99% now" What I'd *really* like to see implemented is something along the lines outlined below - but of course, this will depend entirely on whether or not Timo thinks it is doable - or desirable... I know this would only be applicable if also using the dovecot LDA, because what I want to do requires cooperation at both the deliver and pop/imap ends... 1. Have two 'special' user-specific folders (by special, I mean like the Drafts, Sent, Templates folders) that dovecot controls: a) one, that the user has read-only access to and shows up in his folders list, that is used only for system-related messages, like over-quota notices - and maybe even user-specific log-type errors could be delivered here? b) and one (hidden) that the user does *not* have access to, to temporarily hold messages that come in that are unable to be delivered due to an over-quota condition 2. When user is over quota, have LDA deliver to folder b (yes, accept the message for delivery from the sending mta), and then generate an over-quota message that is delivered to folder a. Optionally, a bounce could be generated to the sender, informing them that their message is being 'held in queue' or something to that effect, due to the recipient being over-quota. 3. Once the user deletes enough mail to come back under quota, dovecot would then move messages from the 'over-quota' folder to his Inbox. Ok, am willing to hear reasons how/why this is a terrible idea... :) -- Best regards, Charles Marcus I.T. Director Media Brokers International 678.514.6200 x224 678.514.6299 fax

Can I define where dovecot.pid should be in the config file on 1.0.0? Nothing is being written to /var/run/dovecot, even after I changed the ownership to dovecot.

[Dovecot] dovecot.org moves to a new server
by Timo Sirainen 23 May '07

23 May '07

Parts of dovecot.org will be down for a few hours while I'm moving to a new server (and to a new ISP as well). The new server won't be virtual anymore, so I'm hoping to get a bit better performance from it as well (the old virtual server had some disk I/O hogs). The DNS records have been using 1 hour TTL for last few days, so this move should be fast for everyone. Thanks to Nebula for hosting dovecot.org for the last 7 months. So, beginning the move by shutting down Postfix and Mailman..
