[Dovecot] Per User Quotas
by Peter Fraser 21 Nov '08

21 Nov '08

HI All Asking for a little patience and a bit of help here. I'm using dovecot-1.1.3_1 with postfix and squirrelmail. I have implemented a global quota successfully. That works fine. I want to now implement per user quotas. So far I have read the howto in the documentation and searched several threads but can't seem to get it working properly. My LDAP server is Windows 2003 Active Directory. Is there any documentation specific to AD that I could look at or any other doc that could help me? My last effort was to put this in dovecot-ldap.conf user_attrs = streetAddress=quota_rule4=*:storage=%$M ,=uid=1002,=gid=1002,=home=/home/vmail/%u and this in dovecot.conf in addition to the other quota rules. quota_rule4 = *:bytes=%$ I then put the quota in the streetAddress area of AD. I'd certainly appreciate any help. Thanks.

[Dovecot] make archive emails undeletable?
by Rob Nichols 21 Nov '08

21 Nov '08

I've been using dovecot for a year or two now, and really like it. I have a fairly simple setup, but I think it's time to get a little more advanced. I keep an "archive" of all my email, both sent and received. Every once in a while I get confused, and accidentally delete something from my archive. I also worry that I'll misconfigure a mail client some day and accidentally wipe out my "trash" folder. I would like some way to prevent deletion in several mailboxes. Is that possible? It looks like ACL could do this, but I can't quite figure out where to start. Any pointers would be greatly appreciated. Thanks, Rob

[Dovecot] Auth Issues - Urgent - Help!
by David Cunningham 21 Nov '08

21 Nov '08

After a few hours of running, I get tons of the following errors in my logs: dovecot: Oct 08 07:41:50 Error: auth(default): ldap(user(a)domain,x.x.x.x): Request queue is full I removed the username and IP, obviously. Any idea how to stop this? I have about 5 Thousand users using horde that login ever 1-5 minutes to refresh their page. I assume it is a setting, but I am confused as to why it doesn't happen almost right away. It seems to take some time to build up. Please help! This is taking my webmail system down hourly.

[Dovecot] Error message in logs since 1.1.6 upgrade
by Guy 21 Nov '08

21 Nov '08

Hi, I've got two imap boxes, one is running 1.1.5 and hasn't exhibited the error below, but the one that's been upgraded to 1.1.6 is showing them. Nov 14 16:06:31 mink dovecot: imap-login: Disconnected (no auth attempts): rip=x.x.x.x, lip=x.x.x.x, TLS handshaking: SSL_accept() failed: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac If this isn't already a known error, is there any extra data I can collect that would help diagnose what's causing it? I haven't a clue where to start with this sort of debugging I'm afraid. Thanks Guy -- Don't just do something...sit there!

[Dovecot] sieve-body extension support for deliver LDA's sieve plugin
by BrunoM 21 Nov '08

21 Nov '08

Hello, I just read your message about sieve and body-extension in Dovecot. Do you have news on that topic? I just have to filter mails containing a particular text fragment, and I cannot do without sieve body, I think.. Thank you for any clue you'd be able to give me ! Regards, Bruno --- Hi Timo & Co, Is there any time frame for updating the deliver LDA's sieve plugin code to that from Cyrus IMAPd v2.3.x? I ask as I'm looking for the functionality of the sieve-body extension, as described here: http://www.ietf.org/internet-drafts/draft-ietf-sieve-body-06.txt This requirement has come up as we're upgrading from a Courier-IMAP/maildrop configuration that has some filtering based on message body content. As an aside, if that time frame is undefined or will be long, if I use maildrop instead as my LDA, will I loose the instant delivery notification via IMAP IDLE? Thanks very much, Scott

[Dovecot] %d in deliver
by Mark Zealey 21 Nov '08

21 Nov '08

Hi there, I run a system that has a lot of virtual users. We invoke deliver from exim and pass the directory to deliver into using the HOME environment variable, so deliver doesn't do any database lookups during the delivery process. The exim pipe environment is described at http://exim.org/exim-html-current/doc/html/spec_html/index.html#toc0239, but basically I'd like to know the domain as well as the user, however deliver doesn't seem to pick this up. Is there any way that you could extend deliver to make it either pick up the domain (or correct username) from the command line, but not do an authdb lookup; or get it to read the domain from an environment variable (or be able to print the contents of an arbitrary environment variable in a formatted string)?

[Dovecot] namespace public / namespace shared - question
by Michal Soltys 21 Nov '08

21 Nov '08

After looking through wiki/config/list I'm still not sure, what exactly is the difference between those two. Even all the examples in dovecot's wiki don't have a single "namespace shared" anywhere. And there's only short mention about the difference in dovecot.conf . Peeking into rfc2342 - would shared namespace relate to "Other Users' Namespace(s)" and public namespace to "Shared Namespace(s)" ? Does perhaps the difference only lie on the client side, depending on the namespace it's asking, while functionally it's the same from the perspective of dovecot ?

[Dovecot] userdb, Dovecot LDA not using mail_location config properly?

[Dovecot] CRAM-MD5 and proxy_maybe
by David Jonas 20 Nov '08

20 Nov '08

When using proxy_maybe CRAM-MD5 authentication fails when the connection is proxied. Is this expected behavior? Is proxy_maybe too simplified for this case? We're using SQL so I could rewrite the query with IFs to fake proxy_maybe and return the password as NULL and nologin as Y, but if it works that way couldn't it work with proxy_maybe? This works: password_query = \ SELECT NULL AS password, host, CONCAT(user,'@',domain) AS destuser \ 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy \ FROM accounts WHERE class='pop' AND domain='%d' This doesn't work if proxied and CRAM-MD5 auth: password_query = \ SELECT \ CONCAT(user,'@',domain) AS user, password, \ host, 'Y' AS proxy_maybe, \ target AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ FROM accounts WHERE \ class='pop' AND domain='%d' AND user='%n' \ LIMIT 1 Thanks, David
