[Dovecot] indexes permissions problem
by Mark Hanford 15 Nov '11

15 Nov '11

Hey all, I did a search but didn't find the answer to my problem, so here goes. I've got a centos 6 server running Dovecot 2.0.beta6 (3156315704ef). For legacy reasons (I'm moving mail from a Dovecot 1.1.1 and FreeBSD box with user home directories NFS mounted), my index files are setup to be in /u/indexes/ On the Dovecot 1.1.1 installation, the perms on the indexes directory is 777 with root:mail ownership. The same thing on the Dovecot 2 / Centos server results in a 'permission denied' error when Dovecot tries to create files. So, I guess my main question is, what perms and ownership should /u/indexes be set to? I've tried several different things before this cry for help... Thanks. Mark

[Dovecot] Dovecot 2.0.15 quota configuration with mbox
by David Ocana 15 Nov '11

15 Nov '11

Hello, I've been trying to set up dovecot 2.0.15, everything seems to work pretty well except for the quota feature. I would like to set a quota limit only for the Inbox folder. I configured two namespaces, according to some posts from Timo Sirainen (http://dovecot.org/list/dovecot/2006-July/014530.html) & (http://www.dovecot.org/list/dovecot/2011-January/056131.html) but I can't configure the quota plugin to act the way I pretend. Here's my namespace configuration: namespace { separator = / prefix = INBOX/ location = mbox:/var/empty:INBOX=/mail/%d/%n:INDEX=/var/dovecot/%d/%n inbox = yes hidden = yes } namespace { separator = / prefix = inbox = no location = mbox:/mail/%d/MAILBOXES/%n:INDEX=/var/dovecot/%d/%n } Quota config: plugin { quota = dirsize:User quota # I've tried with: quota_rule = INBOX:storage=819200K quota_rule = INBOX/*:storage=819200K quota_rule = INBOX/Inbox:storage=819200K # Works with: quota_rule = *:storage=819200K quota_rule = ?:storage=819200K (Same behavior as '*') } Using '*' and '?', is the only way I get it to work, but obviously, quota is calculated summing up all the mailbox folders. I don't know what else to change, any ideas? Is the two namespace configuration correct? Thanks in advance. David

[Dovecot] getenv() in plugin not working
by Trutwin, Joshua 15 Nov '11

15 Nov '11

Hi - new to the list, can't find much on this using google. I'm trying to setup the dovecot DRAC plugin as described here: http://wiki.dovecot.org/HowTo/PopBSMTPAndDovecot#DRAC DRAC is installed and running using this startup command: /usr/local/sbin/rpc.dracd -i -e 5 /etc/postfix/dracd.db I downloaded the drac.c file linked on the above URL: http://www.dovecot.org/patches/1.1/drac.c and built it using this command: gcc -Wall -W -shared -fPIC -DHAVE_CONFIG_H drac.c -I/usr/include/dovecot -L/usr/lib64/dovecot -o drac.so -ldrac Then I copied drac.so to /usr/lib64/dovecot (this is an x86_64 SL 6.1 system - dovecot 2.0.9) and modified my /etc/dovecot/conf.d/20-imap.conf file: mail_plugin_dir = /usr/lib64/dovecot mail_plugins = drac Restart dovecot and try to login and getting these messages for ANY login attempts: dovecot: imap-login: Login: user=<snip>, method=PLAIN, rip=<snip>, lip=<snip>, mpid=4018, TLS server dovecot: imap(<snip>: Error: DRAC: IP environment not given I traced the "IP environment not given" to the drac.c plugin file, and the code is pretty simple: void drac_init(void) { const char *ip_str; struct ip_addr ip; ip_str = getenv("IP"); if (ip_str == NULL) i_error("DRAC: IP environment not given"); Is there anything special that needs to be done for getenv("IP") to report the login IP? I tried to put getenv("RIP") for remote ip and even getenv("USER") as well but always get NULL. Is this API only for dovecot 1.x? If so is there a 2.0 equivalent? The rest of the plugin is very basic... I think this is the last step in getting this setup running. I'd have to have this one last piece force me to run that icky perl program instead. Thank you, Let me know if anything else is needed. Josh

[Dovecot] Question about pop3_reuse_xuidl
by Urban Loesch 15 Nov '11

15 Nov '11

Hi, we are in migration progress from Communigate Pro 5.0.x to Dovecot 2.0.15 with mdbox. We still migrated about 25.000 IMAP accounts from CGP to Dovecot. Also there were still added about 2000 new POP3 Accounts on Dovecot. Now we must migrate about 10.000 POP3 accounts from CGP to Dovecot. At the beginning of our migration we didn't set the "pop3_reuse_xuidl" configuration option to yes. Do you know what happens when we activate the "pop3_reuse_xuidl" option on our running dovecot? Will Dovecot change the uidl value for all existing mails which have set "X-UIDL" in its mailheader, or does Dovecot only change the uidl value for new received and still not downloaded mails? Many thanks and regards Urban Loesch

[Dovecot] XUIDL Migration problems
by Steve H 14 Nov '11

14 Nov '11

Hello All, I am new to Dovecot and the Dovecot mailing list. I am trying to migrate an existing Exim + qpopper - mbox (pop3 only) installation over to Exim + Dovecot using mdir (pop3 and imap) And am running into problems with preserving the XUIDL headers. I am running Dovecot 2.0.14 I have used the mb2md.pl script : http://dovecot.org/tools/mb2md.pl from this page http://wiki2.dovecot.org/Migration/MailFormat to migrate and import the mboxes And have the following pop3 uidl settings in my configuration . pop3_reuse_xuidl = yes pop3_save_uidl = yes protocols = imap pop3 service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } protocol pop3 { pop3_reuse_xuidl = yes pop3_save_uidl = yes pop3_uidl_format = %08Xu%08Xv } The problem specifically is that when I test the migration and import a mailbox, I am able to connect via IMAP using Thunderbird and Outlook 2007 and the Read / Unread status is preserved. However when I connect via POP3 the Read/Unread status is not preserved. I am probably missing something simple, but have been unable to find anything that seems relevant on the Dovecot wiki or searching the mailing lists. Any suggestions would be appreciated.

[Dovecot] patch for UID 0 problem
by Kai Arif 14 Nov '11

14 Nov '11

Hi all, attached you'll find a patch for cmd-thread.c which addresses a problem with certain clients in conjunction with the use of the UID THREAD REFS command: TAG5 UID THREAD REFS us-ascii SINCE 14-May-2011 * THREAD (0)(246)(247)(248)(249)(250)(252)(253)(254)(255)(256)(257)(258)(259)(260)(261)(262)(263)(264)(265)(266)(267)(268) TAG5 OK Thread completed. The first UID delivered (0) is invalid, some clients - @mail for instance - then try to fetch the invalid UID 0 subsequently and run into problems. The patch actually disables the return of (0) and seems to work for us. Please review and - if OK - incorporate it in the next version.

[Dovecot] Managing public folder ACL files
by Keith Edmunds 14 Nov '11

14 Nov '11

We have a customer with a large public folder hierarchy. They occasionally make requests to have the public folder ACLs changed; for example: "please give user X access to all public folders" (that's nearly 1700 folders). Worse: "please give user Y access to all sales folders" (there are 1450 sales folders). The problem is that there are (naturally) spaces in the folder names, which makes command line manipulation challenging. We've ended up with some astonishingly hacky Python scripts that enter each folder starting with (for example) ".sales" and replacing the dovecot-acl file to try to fulfil the above requests. One day our script are going to get it wrong, or requests will become more complex ("give X access all sales/CustA folders, Y access to all sales/CustB folders, and Z access to all sales folders). There must be a Better Way. How do others manage divergent ACLs within large public folder hierarchies? Thanks, Keith

[Dovecot] [re] patching dovecot for managesieve/sieve
by Scott Lewis 14 Nov '11

14 Nov '11

My apologies for the repost yesterday; it was not intentional. I was attempting to post a followup from my mobile, when something went awry with the editing options on my phone. Anyway.. I have managed to download and compile my own patched dovecot/dovecot-sieve/dovecot-managesieve modules from scratch, with Thanks to this page hardc0l2e.wordpress.com/2010/02/26/managesieve-with-dovecot-on-centos-5-4/ But when I run http://mydomain.com/src/configtest.php , I am still getting the following rather non-descriptive error: "I could not determine the capabilities for Sieve Mail Filtering. Perhaps connectivity with ManageSieve server (if backend=ManageSieve) is bad?" Where else can I look to resolve this? should managesieve show up as its own /etc/init.d service? Or does dovecot simply control it? How can I confirm that deliver is being used as my LDA? Thanks again, Scott
