[Dovecot] Seg fault in dovecot/auth 2.0.15
by Mark Goldey 15 Nov '11

15 Nov '11

Folks: I've been running Dovecot 2.0.7 on a Qmail / Vpopmail installation built on Debian Squeeze, with no problems for about a year. Dovecot is used for IMAP/S auth only. Dovecot is built from source. I just upgraded to 2.0.15 but it segfaults whenever an IMAP auth is attempted, regardless of the user who tries to login, whether by webmail (Roundmail) Android phone (K-9 Mail) or iPad (Roundmail) I downgraded to 2.0.13 but the segfault persisted. Re-installed 2.0.7 and that cleared it right up. Here's the pertinent details from 2.0.15. Anything else I can provide? root@XXX:/# uname -a Linux XXX 2.6.32-5-686 #1 SMP Wed Jan 12 04:01:41 UTC 2011 i686 GNU/Linux root@XXX:/# dovecot -n # 2.0.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no first_valid_uid = XXXX last_valid_uid = XXXX log_path = /var/log/dovecot.log mail_debug = yes passdb { driver = vpopmail } protocols = imap service imap-login { inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } process_limit = 128 vsz_limit = 64 M } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = vpopmail } verbose_ssl = yes Here's a failed login transaction from /var/log/dovecot [snip -- 10 lines or so.

[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 15 Nov '11

15 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 15 Nov '11

15 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

[Dovecot] Restoring Mails from Backup Archive
by Andreas Cieslak 14 Nov '11

14 Nov '11

Hi List, i am trying to restore mails from an backup-archive which was made with rsnapshot. All the mails in the archive look similar like the following: -rw------- 2 1014 1015 3308 8. Aug 13:42 1312803768.V809I266a00aM505178.server:2,ST Now I copy the files from the archive into the Maildir/cur directory of the user. Then I set the permissions etc. and log in with the user account via Squirrelmail. The restored mails aren't in the INBOX, and when I go into the Maildir/cur dir of the user, the restored mails are gone. Possibly deleted after the login. Had anyone some similar experiences ? Any hints ? Kind regards Andreas

[Dovecot] metadata plugin problems
by Georg Martius 13 Nov '11

13 Nov '11

Hi, I have trouble with the metadata plugin. I compiled dovecot 2.0.15 from source and also the plugin [2] separately. I work on debian/lenny. I had some trouble compiling it (autoconf somehow didn't insert the DOVECOT_IMAP_INCLUDE variable, I have not idea why) Anyway, I did as described in [1]. Do I have to create: the file /var/lib/dovecot/shared-metadata ? The server starts without errors, but I get for instance the following error message: "Failed to write some annotations for 'Contacts' on the IMAP server. SetMetaData failed, server replied: A000076 NO Parsing entry failed" from my KMail. How can I test that the plugin is actually active and working? Any help would be appreciated. Regards, Georg [1]http://www.mail-archive.com/dovecot@dovecot.org/msg38887.html [2] http://hg.dovecot.org/dovecot-metadata-plugin

[Dovecot] Dovecot v2.0.13 unix_listeners
by Matthew Brown 13 Nov '11

13 Nov '11

Could somebody be able to explain to me what the various unix_listeners do in the Dovecot 2.x configuration (specifically in 10-master.conf). Currently, for postfix to use for local delivery, I have: service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } and for auth I have: service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { mode = 0666 user = vmail } } So what does each one specifically do? Also, does somebody know of a resource that can explain the mode setting? I couldn't seem to find anything on the wiki.. Sorry if these questions seem simple, Im still trying to get a grips with dovecots workings. MDA: Dovecot v2.0.13 MTA: SMTP User & Virtual Domain Management: MySQL Cheers, Matthew

[Dovecot] TLS Authentication Confusion
by Carlos Mennens 11 Nov '11

11 Nov '11

I asked a user today to make sure his incoming and outgoing email was using TLS. He told me it wasn't possible because my Dovecot / Postfix daemons were only listening on TCP 25 & 143 according to a port scan he did. He told me the only way I could enable encrypted secure sessions between the client & server is to enable port 993 (IMAPs). I told him that TLS is supported on my mail server over the default ports TCP 25 / 143 and that many consider IMAPs to be legacy. I sent him a telnet session of my PC communicating with my server & it shows TLS is available. I just wanted to be sure I was correct with the information above or am I completely wrong and I do indeed need TCP port 993? I know this is the Dovecot mailing list but since Dovecot and Postfix both use and support TLS in their configuration files, I figured I would ask here for your help! carloss@pc1:~$ telnet mail.holyghost.org 25 Trying 192.168.4.100...

[Dovecot] Restarting dovecot periodically fails with "Socket already exists: /var/run/dovecot/anvil"

[Dovecot] patching dovecot for sieve/managesieve support, centos 5.6?
by Scott Lewis 10 Nov '11

Hi all, I am having real trouble when attempting to patch dovecot 1.2 to include the Pidgeonhole sieve support on my CentOS 5.6 x64 mail server. I am relatively new to the programming side of linux, but I am not having a lot of luck when trying to get this thing to compile.

Perhaps connectivity with ManageSieve server (if backend=Managesieve) is bad? thanks in advance!

[Dovecot] Corrupted transaction log file

Hi, I'm experiencing a problem I need some pointers to debug.

[Dovecot] Please advise on very fast search
by Alexander Chekalin 09 Nov '11

09 Nov '11

Hello, I try to create some kind of mail backup system. What I need is system that will store mail for the whole domain, and allow me to restore messages from/to specified email at that domain. The scheme is pretty simple: on our main mail server the SMTP server itself has a rule to send a copy of every message to 'backup(a)backupserver.host', and the backupserver.host domain is placed nearby on second server. The SMTP on second server do simple 'catchall' redirect of all messages to the single box. There is also a Dovecot that takes care for remote IMAP access to that box. And, finally, I've create some scripts to sort all messages in INBOX to folders named after message's date. So I have a lot of mailboxes inside the catchall box: INBOX 2011.11.03 2011.11.04 2011.11.05 2011.11.06 ...etc... and each folder holds messages for that day. Simply, and works perfectly. The problem is that when my archive become big (several years), it appears to be painful to find specified message(s). When someone suddenly needs to find his/her old message, it is mostly guesses like 'I think the message was between june and july of 2009, or maybe month or two before that', so I need to search all mailboxes (with 1000's messages in each). And it takes really long time. I tried to play with Dovecot indexes, but it won't help too much. The bad part is that I need to search for all emails in each message headers, not only for "From" or "To", since some messages are sent to maillists soe "To" = list address, not person's personal email. Then I tried to index messages on my own, storing info on emails into MySQL database ('email' -> 'mailbox', 'message filename'), but soon I find out that message files can be renamed by Dovecot. Could you please advice me how to speed up message search? Sorry for such a long question, hope you can help! Yours, Alexander Chekalin

You could then sum them up with some scripting to produce the total. Unfortunately they are the uncompressed sizes, but maybe simply dividing by 2 would give approximate size? :) (You could get the compressed sizes from dovecot.map.index files with doveadm dump and mapping their contents to the older than 1 year message UIDs, but this gets difficult.)

Having > 10 TByte mailstore filesystem-checks takes too much time. At the moment we have four different partitions, but I don't like to set symlinks or LDAP-flags to sort customers and their domains to there individual mount-point. I'd like to work with mdbox:/mail/%d/%n to calculate the path automatically. How do you handle >> 10 TB mailstore? I'm very interested in the feature "alternative mailstore" with mdbox, because that makes it very easy to use at least TWO filesystems without any tricky configuration. I think I'd love to have <n> alternative mailstores. Why does dbox doesn't look for its m.*-files in more then two directorys? Sure, looking in 4 directorys would lead to four disc operations, but maybe it could be very helpful.

[Dovecot] Attachements with SIS : shauld all the same files share the same inode ?

Hello. I configured SIS , and all seems to work well, but I noticed something strange : For exemple, this attachement : 6e/2d# ls -al 6e2df299* | sort -n 104 instance of -rw------- 104 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-ffd0d1xxxx The files are hardlinked, so it seems ok, but I also see 9 others files in the same directory : -rw------- 1 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-0519df2a94fc9a4e1f4100008a6b99b6 -rw------- 1 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-1790b92994fc9a4e1a4100008a6b99b6 as you can see, same prefix, If I compare them with diff, they are all the same files. ls -i show that 104 have the same inode, as expected, and the 9 remaining files have different inodes. I expected all the files share the same inodes. Is there something wrong here ?

[Dovecot] How to define ldap connection idle
by Aliet Santiesteban Sifontes 08 Nov '11

08 Nov '11

I'm having a problem with dovecot ldap connection when ldap server is in another firewall zone, firewall kills the ldap connection after a determined period of inactivity, this is good from the firewall point of view but is bad for dovecot because it never knows the connections has been dropped, this creates longs timeouts in dovecot and finally it reconnects, meanwhile many users fails to authenticate, I have seen this kind of post in the list for a while but can't find a solution for it, so my question is how to define a idle ldap time in dovecot so it can reconnect before the firewall has dropped the connection or just close the connection under inactivity so when a user authenticate doesn't fails for a while until dovecot detects that the connection has hanged. Is this a feature request or there is already a configuration for this??? Thank's in advance and congrats tu Timo for this great app.

[Dovecot] Accessing a strange mailbox
by Micah Anderson 07 Nov '11

07 Nov '11

I have a user who has a mailbox called: A----->B It seemed to work in courier fine, they managed to create it, and there are mails in it. However, dovecot is not letting the user access it, the IMAP server gives an error. I tried to rename it but I would also get an error: # doveadm mailbox rename A-----\>B AtoB doveadm(root): Error: Can't rename mailbox A----->B to AtoB: Mailbox doesn't exist: A----->B # doveadm mailbox rename A----->B AtoB doveadm(root): Error: Can't rename mailbox A----- to AtoB: Mailbox doesn't exist: A----- # doveadm mailbox rename 'A----->B' AtoB doveadm(root): Error: Can't rename mailbox A----->B to AtoB: Mailbox doesn't exist: A----->B # doveadm mailbox rename "A----->B" AtoB doveadm(root): Error: Can't rename mailbox A----->B to AtoB: Mailbox doesn't exist: A----->B # How can I deal with this mailbox (using mdbox here)? Thanks! --

[Dovecot] Converting from 1.12 to 2.0 questions about mail location?
by Knute Johnson 06 Nov '11

06 Nov '11

I'm building a new server and using a newer version of ubuntu server that uses Dovecot 2.0. I thought I would like to use Maildir instead of the mbox that was used in the previous server. What do I have to do to convert my mbox mail to Maildir? Or should I just use mbox and copy it over :-)? Thanks, -- Knute Johnson

[Dovecot] Safely restoring backups
by Micah Anderson 05 Nov '11

05 Nov '11

I'm trying to determine what the best way to restore mail with mdbox is. Restoring using maildir was trivial, I just used rsync --ignore-existing which wrote any mails that were removed and didn't touch things that already existed[1]. With mdbox things have become more complicated, and I haven't found a way to restore mail that doesn't result in many message duplicates. My backup setup is simple, I'm doing daily rsync backups of user's mailstores, as well as weekly backups, so I end up having on my backup server daily.1, daily.2, daily.3, daily.4, weekly.1, weekly.2... each containing the entire contents of the user's mdbox. The different restore methods I've tried are: 1. I tried rsyncing the different backup directories back to the mail storage host, and then doing: 'dsync -R backup -u $user mdbox:/path/to/to/daily.1/mdbox'[2] 'dsync -R backup -u $user mdbox:/path/to/to/daily.2/mdbox' This works ok, but it gives duplicates of every mail that already exists for every daily/weekly I dsync. This is what the rsync --ignore-existing avoided. This is particularly annoying if I restore the weekly, and multiple daily directories, because then you get a copy for every one you restore. I had thought that the individual message's GIDs would keep them from being duplicated? 2. I also tried to use 'doveadm import' in two different ways. The first way I created a 'restored_from_backups' folder and then import each of the daily.#, weekly.# mdboxes into their own subfolder within that folder, for example: 'doveadm import -u $username mdbox:/path/to/daily.1/mdbox restored_from_backups/daily1 all' 'doveadm import -u $username mdbox:/path/to/daily.2/mdbox restored_from_backups/daily2 all' ... etc. I then go through and subscribe the new folders[3] and the user ends up with a folder structure like this: restored_from_backups/ daily.1/ INBOX Trash folder1 folder2 daily.2 INBOX Trash folder1 folder2 etc. This works fine, except that it results in the user having a entire duplicate copies of their mailbox for each daily/weekly that I restore. That will quickly bring people over quota. 3. I also tried to use 'doveadm import' to import all the different directories all into the same restored_from_backups directory, so there are no subdirectories for each daily/weekly under restored_from_backups, like so: 'doveadm mailbox create -u $user -s restored_from_backups' 'doveadm -v -D import -u $user mdbox:/path/to/daily.1/mdbox restored_from_backups all' I then go through and subscribe the folders[3]. Using this method, the 'restored_from_backups' mailbox is created, and populated with the folders. The only problem with this method is the same as method #1: for every backup I restore, mails are duplicated. Is there a way I can restore things from backup and avoid duplicates? Is there another method I should try? thanks for any ideas, pointers, suggestions for improvement, etc. micah 1. this would of course bring back mails that were deleted, but that was fine as the user could deal with that. 2. yes, I know I could setup dsync on the backup server, and use dsync directly to pull the mails from there, but this is complicated in my situation due to how the backupserver works. 3. why doesn't doveadm import have a -s option to subscribe? --

[Dovecot] Newbie Question/Feature Request
by Michael Papet 05 Nov '11

05 Nov '11

Hi, I'm working on a plugin for qpsmtpd (a perl smtp frontend) that delivers mail via dovecot's LDA. I can only get mail delivered by writing the email to file, then calling 'deliver -d someone -f someone-else < /path/to/temp/email' All good, expected behavior. A perl snippet: local $/=undef; open FH, "< ./demo.mail"; my $stringified = <FH>; # this is roughly equivalent to how other LDA queues work. close FH; open (CMD_OUT, " /usr/lib/dovecot/deliver -f somedude\(a)someplace.com -d anotherdude\(a)destination.dom $stringified |"); my $test = <CMD_OUT>; print $test; The above code errors out because the expected behavior is $stringified is supposed to be a file name. It would be great if deliver could be fed the email as a string so I don't have to add a step of writing to file. Or, maybe there's an undocumented method? Thanks. mpapet

[Dovecot] dsync with quotas
by Micah Anderson 05 Nov '11

05 Nov '11

I have been working on converting people from courier maildir -> dovecot mdbox and during some of the dsync runs I'm seeing the quota_exceeded_message be printed as an Error: dsync(<user>): Error: Can't save message to mailbox INBOX: You are over quota. To avoid losing mail, immediately empty your Trash and Sent folders and \ delete emails with large attachments. dsync(<user>): Info: INBOX: Couldn't keep all uids^M Its possible the user was over quota on the originating courier side, but I would still like to migrate their mail proprely to mdbox, but it seems like being over quota is inhibiting that. Are the quota calculations including both the maildir files as well as the converted mdbox files, resulting in a double counting? I'm not entirely sure if the messages above indicate that the migration failed for that user or not, so I've been manually increasing their quota, then redoing the dsync mirror until it works properly. I wonder if it would be better if I turned off quota entirely during migration so I don't run into this problem? thanks, micah --

We use NTP. Indexes are in a iSCSI raid 10, mailboxes in raid5. No NFS. We have detected that sometimes all users get disconnected from roundcube at the same time.

Note the time difference of 45 seconds. > Nov 3 09:23:07 buzon dovecot: imap(mcrivero@mydomain): Connection closed bytes=0/295 The dotlock warning isn't related to this. My guess: NFS was being extremely slow here, some operation took 45 seconds and Roundcube decided to abort before that. The "timestamp is different" check doesn't work 100% correctly if the filesystem operations take more than a second.

[Dovecot] Bad creation timestamp of migrated mails (maildir format)?
by Lukas Weiß 05 Nov '11

05 Nov '11

Hello everybody, ive just switched to dovecot imap because dbmail i used before is not developed any further and sql storage is difficult to backup. Ive done that, by setting up dovecot with maildir format and copy mails from old dbmail to new dovecot imap server with my mail client (thunderbird). Unfortunately migrating to dovecot brought me some problems with my Android K9 Mail client: Sync with IMAP-Server shows me only the oldest mails. I think the problem is, that K9 only fetches the newest mails (25) from the server (to save memory etc). Which mail is "new" is probably determined by creation timestamp of the email-files in my mailbox, which was copied newest first on migration from dbmail to dovecot. So the older mails have the newer creation timestamp on file system. Do you have any suggestions how to fix that problem? Maybe migrate to dbox mailbox format? BTW: New mails show up correctly, as the creation timestamp is new. Thanks Lukas

Next problem :-) side effect: my test setup (some commits ago) with fts = lucene in plugin section (ftps_lucene plugin without stemmer support): SEARCH header is not working (empty result sets, no logging). Tested in different circumstances (and also happening with virtual folders). Simply disable fts option (while module is still loaded) or use fts=sqat to have header search working correctly again.

A particular reply (not to the list) has told me to try: " Add to service lmtp: process_min_avail = 20 " And yes, it works (unless for me), so I want to share it with everybody.

What the "process_min_avail = 20" in service lmtp (or anywhere else) exactly imply? cannot find a reference in wiki2 . I suppose it means than 20 lmtp processes are always open waiting for new connections and so reducing startup latency, isn't it?

[Dovecot] imap proxy for Gmail
by Jumping Mouse 04 Nov '11

04 Nov '11

Hello, b I have a situation were I want to be able to give teachers access to their Google apps for education email through Squirrelmail. The network that they are on blocks gmail. I am able to get Squirrelmail to communicate with Gmail via imap. I am looking at getting persistant imap connections to improve the user experience. I have looked at IMAPPROXY but this application is not compatible with the gmail imaps (ssl-encrypted imap over port 993). I recall reading somewhere that Dovecot has a built in imapproxy that could be used for this. Can someone please point me to documentation or other information on how I might achieve the above stated goal? Thanks, Kafriki

[Dovecot] Proxy and Virtual IMAP Folders
by Pedro Paixao 04 Nov '11

04 Nov '11

Hi all I am a newbie to dovecot and I would like some help clarifying a feature to determine if I can use it in my project. Is is posible to use the virtual plugin, in a IMAP proxy configuration, in a way that the virtual plugin searches messages on the real server? Here's my scenario: [Client]----[Dovecot Proxy]-----[Real Imap Server] Client connects to Dovecot Proxy and gets all the folders that are on the Real Imap Server, plus some virtual ones (generated by Dovecot Proxy) that search for messages on the real server. In my config the Dovecot Proxy has no email messages, real folders, or local delivery. I would like to thank you in advance for ant help and support. All the best Pedro
