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

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. Here's what happens: [root@mail ~]# whereis dovecot dovecot: /usr/sbin/dovecot /etc/dovecot.conf /usr/lib/dovecot /usr/libexec/dovecot /usr/share/man/man8/dovecot.8.gz [root@mail dovecot-1.2-sieve-0.1.19]# ./configure --with-dovecot=/usr/lib/dovecot ... checking whether to build static libraries... yes dovecot-config not found from /usr/lib/dovecot, use --with-dovecot=PATH to give path to compiled Dovecot sources or to a directory with the installed dovecot-config file. configure: error: dovecot-config not found -- I get this message regardless of whether I set --with-dovecot as /usr/sbin/dovecot, or /etc, or /usr/libexec/dovecot. I have SquirrelMail 1.4.22 running, and the avelsieve front-end seems happy enough. when I visit https://mail.mydomain.com/src/configtest.php, I get: Avelsieve plugin details: backend = ManageSieve ERROR: I could not determine the capabilities for Sieve Mail Filtering. Perhaps connectivity with ManageSieve server (if backend=Managesieve) is bad? thanks in advance!

[Dovecot] Corrupted transaction log file
by Peter Mogensen 09 Nov '11

09 Nov '11

Hi, I'm experiencing a problem I need some pointers to debug. I'm running Dovecot 2.0.15 and have a client which keeps causing log-entries like: Nov 4 15:10:42 mail dovecot: imap (test(a)aaaone.net) Error: Corrupted transaction log file /mail/3340444/.TestMails/dovecot.index.log seq 2: indexid changed 1320419300 -> 1320419441 (sync_offset=0) Nov 4 15:10:42 mail dovecot: imap(test(a)aaaone.net): Error: Corrupted transaction log file /mail/3340444/.TestMails/dovecot.index.log seq 2: Invalid transaction log size (4476 vs 4360): /mail/3340444/.

Starting up Thunderbird with a login to the account seems to be enough to cause this. (To my knowledge this causes a series of STATUS command and then IDLE). The installation is using Maildir and lock_method = fcntl on local disks. /Peter

[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.)

[Dovecot] Multiple Patitions with with mdbox
by Peer Heinlein 09 Nov '11

09 Nov '11

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 ?
by Yann Dupont 08 Nov '11

08 Nov '11

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

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 --

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

[Dovecot] imap proxy for Gmail
by Jumping Mouse 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

Explaining this function, i try to use a imap folder like a "collector folder", the user append a message from outside (ie another imap or pop message) to this folder, and i don't want to copy this message, i need to redirect it to another folder outside from user's maildir. Well, i try to base it in zlib plugin, with was the o_stream_create_gz(). Inside the o_stream_create_gz has the Output, it's a copy from the original output. I Try to replace this output, with another one, that i try to create to another location, without sucessfull. struct ostream * o_stream_create_X_list(struct ostream *output, struct istream *input, const char *type) { struct emexis_ostream *X_stream; struct ostream *new_output; int fd; fd = open("/tmp/email",O_WRONLY); new_output = o_stream_create_fd_file(fd, 0, TRUE); o_stream_cork(new_output); emexis_stream = i_new(struct emexis_ostream, 1); emexis_stream->ostream.sendv = o_stream_X_sendv; emexis_stream->ostream.flush = o_stream_X_flush; emexis_stream->ostream.iostream.close = o_stream_X_close; emexis_stream->output = new_output; emexis_stream->input = input; o_stream_ref(new_output); return o_stream_create(&X_stream->ostream); } With this new o_stream, i got this error. Oct 27 15:14:24 brc dovecot: imap(alex(a)exemplo.com.br): Error: o_stream_send_istream(/storage/gss/emexis/messages/ exemplo.com.br/alex/Maildir/.Emexis.Ext-Blacklist/tmp/1319735664.M568409P30815.brc) failed: Bad file descriptor Oct 27 15:14:24 brc dovecot: imap(alex(a)exemplo.com.br): Error: o_stream_flush(/storage/gss/emexis/messages/ exemplo.com.br/alex/Maildir/.Emexis.Ext-Blacklist/tmp/1319735664.M568409P30815.brc) failed: Bad file descriptor Oct 27 15:14:24 brc dovecot: imap(alex(a)exemplo.com.br): Error: write(/storage/gss/emexis/messages/ exemplo.com.br/alex/Maildir/.Emexis.Ext-Blacklist/tmp/1319735664.M568409P30815.brc) failed: Bad file descriptor There is something wrong Timo ? Like missing something or i need to rewrite another funcion ? Tks !!!

[Dovecot] doveadm delete-user ?
by Jan-Frode Myklebust 04 Nov '11

04 Nov '11

IMHO it would be great if we could both provision and un-provision users without having the provisioning system mess with files in the filesystem. Provisioning new users works fine since dovecot will create all files/directories on first login, but I haven´t found the tools to un-provison them. I see "doveadm mailbox delete" can delete individual mailboxes, but what about indexes, sieve-scripts and home-directories? Are there any tools to clean out these ? -jf

[Dovecot] Restricting IMAP access
by Thierry de Montaudry 04 Nov '11

04 Nov '11

Hi list, I have a setup with postfix+dovecot+mysql unser CentOS 5, running 50 odd domains with virtual users. Access is allowed for public POP3, and a webmail on apache+PHP solution through local IMAP. I'm not gonna give you the long story about the why, but I'm looking for a way to give public IMAP access only to one domain, knowing that users log in with full email (user(a)domain.tld) Anybody has a trick for that? Running dovecot 2.0.13. I know there should be a way to do it through the database, but quite heavy change on our side for a million odd users. Regards, Thierry

[Dovecot] Dot Lock timestmap, users disconnections from roundcube
by Maria Arrea 04 Nov '11

04 Nov '11

Hello. We are running dovecot 2.0.13 with mdbox+zlib on RHEL 5.7 x64, ext4. 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. In dovecot logs we hundreds of lines like this: Nov 3 09:23:07 buzon dovecot: imap(mcrivero@mydomain): Warning: Created dotlock file's timestamp is different than current time (1320308587 vs 1320308542): /buzones/mydomain/03/67/mcrivero/subscriptions Nov 3 09:23:07 buzon dovecot: imap(mcrivero@mydomain): Connection closed bytes=0/295 Nov 3 09:23:07 buzon dovecot: imap(delolmo@mydomain): Warning: Created dotlock file's timestamp is different than current time (1320308587 vs 1320308542): /buzones/mydomain/15/77/delolmo/subscriptions Nov 3 09:23:07 buzon dovecot: imap(delolmo@mydomain): Connection closed bytes=0/295 I have been googling but I only see problems with remote NFS, our setup does not use NFS.

[Dovecot] IMP, Dovecot and multiple namespaces
by Rick Romero 04 Nov '11

04 Nov '11

Hey guys, I'm wondering what the best way is to be backwards compatible with Courier mailbox formats and not duplicate mailbox trees with Dovecot. Is anyone doing this right now? My Dovecot 2.0.13 is configured as follows for Namespaces: namespace { inbox = yes location = prefix = separator = . } namespace { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } So I should have an INBOX, plus additional root folders - rather than the Courier default of all folders being subfolders of the INBOX. So when I run LIST in IMAP I get - 08 LIST "" % * LIST (\HasChildren) "." "INBOX" * LIST (\HasChildren) "." "Spam" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Junk" * LIST (\HasNoChildren) "." "Drafts" Which looks fine. The problem is, IMP (old and new) show two sets of mailboxes (one for each namespace) like so: INBOX Spam Spam.Over10 Sent INBOX.Spam INBOX.Spam.Over10 INBOX.Sent (etc) I assume IMP is walking the INBOX because it says it has Children, and displaying those Children - The Horde team is telling me that's the root of the problem. It makes sense, but I'm not sure what the real solution is. Is it possible to disable Children for a mailbox when an alternate hidden namespace matches the mailbox name? Does that make sense? Or, is there another option I change change in the dovecot config to accomplish the same? Rick

[Dovecot] Different default realm per listener
by Kai Arif 04 Nov '11

04 Nov '11

Hi all! I want create a large IMAP server setup where dovecot is listening on multiple interfaces and needs a different default realm on each interface. I'm using dovecot 2.0.5 on FreeBSD9 and authenticate against a LDAP database. I found an old mail thread from 2007 that said I'm basically screwed. Has that change since than? Is there any way to use different default realms per listener?

[Dovecot] LDAP w/SASL "Active Directory" authentication failing.
by David Varela 04 Nov '11

04 Nov '11

Hello, I am running a Dovecot server (version 1.2.17) on FreeBSD 8.2, using LDAP to authenticate Active Directory users. I can successfully bind and authenticate using PLAIN and LDAP without SASL, but obviously passwords for the bind user and the user being authenticated are being passed in plain text. I've attempted to configure my server to us SASL however when I attempt to authenticate a user I see authentication failures. I reviewed the security log on my domain controller and see that the bind user is binding properly, so the issue appears to be orginating from the user authentication, however I cannot determine what the issue is. Here is all the information regarding my configuration, along with the logs from the server: Dovecot -n # 1.2.17: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-RELEASE i386 ufs log_path:

I works but i would like that the imap and pop session get executed even if the post-login script fail. my postlogin script is very simple: #/etc/dovecot/conf.d/10-master.conf service imap { executable = imap imap-postlogin } # service imap-postlogin { executable = script-login /usr/local/bin/postlogin.sh unix_listener imap-postlogin { } } service pop3 { executable = pop3 imap-postlogin } #/usr/local/bin/postlogin.sh echo "UPDATE mailbox SET last_login = now() WHERE username = '$USER'" | mysql -upostlogin -pXXXXXXXX postfixadmin exec "$@" Thanks in advance Osvaldo

[Dovecot] What owner/permissions for virtual homes?
by sean darcy 04 Nov '11

04 Nov '11

VirtualUsers.Home.txt: The directory layouts for home and mail directories could look like one of these (in the preferred order): 1. Mail directory under home, for example: home='/var/vmail/domain/user/' mail='/var/vmail/domain/user/mail/' Who should be the owner of these directories, with that permissions? Does it make a difference if it's /home/vmail rather than /var/vmail? Thanks, Jay

[Dovecot] doveadm 'proxy list' or 'who' not working ?
by de Lafond Guillaume 04 Nov '11

04 Nov '11

Hi, I switched from dovecot 1.2.* to 2.0.* for a mail proxy. I try to play with the new cool utility doveadm, but I don't manage to get results from it. # /usr/local/dovecot-2.0.15/bin/doveadm proxy list username proto src ip dest ip port # As 'proxy list' does not return anything, I tried with 'who' # /usr/local/dovecot-2.0.15/bin/doveadm who -a /var/run/dovecot-socket-auth/anvil username # proto (pids) (ips) # I think it should display something as I have many user connected : #ps axww | grep imap ... 21194 ? S 0:11 dovecot/imap-login [13 connections (8 TLS)] 21195 ? S 3:38 dovecot/imap-login [47 connections (38 TLS)] 29463 ? S 1:00 dovecot/imap-login [210 connections (183 TLS)] ... I should have something that is not well configured.. but I don't manage to find it. Does anybody have an idea where I should look to solve this ? Here is my dovecot.conf : # /usr/local/dovecot-2.0.15/bin/doveadm config # 2.0.15: /usr/local/dovecot-2.0.15/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2

[Dovecot] POP server migration and duplicate messages.
by Ernie Dunbar 04 Nov '11

04 Nov '11

I'm having trouble with Dovecot where my mail client (if it matters, I'm using Evolution) collects some duplicate messages when switching between POP servers that have the same messages on them. I'm doing this as a test for server migration for all of our clients. Here's my procedure: 1. set up Dovecot and Exim on the new server so that everything works like on the old server. The old server also uses Dovecot and Exim, so very few things changed. 2. On the new server, use NFS to access the users' Maildirs on a remote NFS server. 3. Sync the Maildirs on the NFS store from the old server with SCP (and I do a quick SCP sync on my own Maildir during testing to ensure that this process is quick). 4. Check mail in Evolution on the old server. 5. Change Evolution's server settings to use the new server. 6. Check mail again. Evolution is set to keep messages on the server for one week, and about 20 of the 184 messages on the server keep getting re-downloaded. From a random sampling, the UIDL of the messages checks out between both servers, so I really don't understand what's going on here. If this is just a bug in Evolution, then that means I can just go ahead with the full migration and hope that people aren't going to be stuck with re-downloading their entire mailbox which in some cases, means hundreds or thousands of messages.

[Dovecot] GSSAPI and deny=yes passdb
by Sergey Urushkin 04 Nov '11

Hi. Is it possible to use GSSAPI authentication and deny passdb together? Seems it doesn't work as I expect: GSSAPI doesn't check deny passdb, so I'm not able to restrict access to GSSAPI-users. I can see these in logs when user tries to connect with PLAIN authentication (via pam_krb5): Oct 4 11:14:31 vm03 auth: Debug: passwd-file(testuser,172.17.0.123): lookup: user=testuser file=/etc/dovecot/auth.d/.passwd-deny Oct 4 11:14:31 vm03 dovecot: auth: passdb(tesetuser,172.17.0.123): User found from deny passdb But that's what I see if user logs in with GSSAPI: ...

[Dovecot] dovecot evaluation on a 30 gb mailbox
by Rajesh M 04 Nov '11

04 Nov '11

hi all i use qmail toaster. i recently changed over to dovecot. posting below my evaluation on the same my machine dual core dual xeon 5140 processor, with 4 gb ram, centos linux with qmailtoaster i had setup a qmail tap account which backups up data for a client of mine mailbox size over 30 gb setup dovecot with squirrelmail and logged in it had over one hundred and thirty nine thousand emails 139019 emails in the 30 gb mailbox Reports 1) first login : took 7 minutes to parse 139019 mails but never timed out. this was simply impossible with courier 2) the next login it took 5 seconds by which time the mail numbers increased to 139045 3) next i changed squirrelmail display preference to list 500 mails per page and then clicked on inbox ... expecting dovecot to take atleast around 1-2 mins to show the mails ... the mails were displayed in just 8 seconds .. awesome performance qmailtoaster is simply waiting for a dovecot integration i am evaluating the stability of dovecot now in the next 2-3 weeks i post stability report rajesh

[Dovecot] Expire plugin not executing for sieve plugin?
by Dan Swartzendruber 04 Nov '11

04 Nov '11

Running dovecot 1.2.12 on ubuntu 10.10. Here is the problem: I have mysql backend for expire. I am using the dovecot-postfix package which creates /etc/dovecot/conf.d/01-mail-stack-delivery.conf which looks like this: # Some general options protocols = imap imaps managesieve disable_plaintext_auth = no ssl = yes ssl_cert_file = /etc/ssl/certs/ssl-mail.pem ssl_key_file = /etc/ssl/private/ssl-mail.key ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM mail_location = maildir:~/Maildir auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ # IMAP configuration protocol imap { mail_max_userip_connections = 10 imap_client_workarounds = outlook-idle delay-newmail mail_plugins = expire } # LDA configuration protocol lda { postmaster_address = postmaster mail_plugins = sieve expire quota_full_tempfail = yes deliver_log_format = msgid=%m: %$ rejection_reason = Your message to <%t> was automatically rejected:%n%r } # Plugins configuration plugin { sieve=~/.dovecot.sieve sieve_dir=~/sieve # If the user has no personal active script (i.e. if the file # indicated in sieve= does not exist), use this one: sieve_global_path = /var/lib/dovecot/sieve/default.sieve } The sieve is: require "fileinto"; require "imap4flags"; if header :contains "X-Spam-Flag" "YES" { setflag "\\Seen"; fileinto "SPAM"; stop; } Originally, this did not have the setflag or stop - I added them hoping to fix the problem, but no luck. The problem is this: when spam assassin has flagged a message as spam, the sieve runs and the message is in fact filed into the SPAM folder, but no expire entry is added to the database. If I move such a message from the SPAM folder to the Inbox and then back to SPAM, voila, I *do* get the entry created. Here is the mysql table before and after I did the move/move: mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | +----------+---------------+--------------+ 9 rows in set (0.00 sec) mysql> select * from expires; +----------+---------------+--------------+ | username | mailbox | expire_stamp | +----------+---------------+--------------+ | dswartz | Deleted Items | 1319720163 | | dswartz | Sent | 1319120165 | | denise | Trash | 1319139920 | | samantha | Trash | 1319136146 | | denise | Sent | 1319655872 | | danielle | Sent | 1319192230 | | samantha | Sent | 1319268855 | | dswartz | Trash | 1319725884 | | samantha | SPAM | 1321504531 | | dswartz | SPAM | 1321714666 | +----------+---------------+--------------+ 10 rows in set (0.00 sec) It's almost like the fileinto stuff is not running the plugin code at all, or am I totally on drugs? If I can't get a fix for this, I at least now can think of a hack to "fix" it. e.g. every night, run a script that adds a "now" timestamp for everyone's SPAM folder to trick the periodic expire tool code into checking that folder, but obviously I'd rather have a real fix :) If this is just 'how it works', is it better in 2.0?

[Dovecot] iterate_query not working
by Piotr NetExpert 04 Nov '11

04 Nov '11

Hi, I have got iterate_query defined in dovecot-sql.conf.ext. However when I run a command like: doveadm search -A BEFORE 10d I receive an error message (Failed to iterate ...) There is an error message in a log file too: Error: Trying to iterate users, but userdbs don't support it The problem is that monitoring a database server shows that dovecot does not try to execute any query. What I am doing wrong? password_query lookups work fine. -- pozdrawiam Piotr Szafarczyk http://www.netexpert.pl

[Dovecot] Getting the SMTP envelope through IMAP?
by Hadmut Danisch 04 Nov '11

04 Nov '11

Hi, just a simple question about dovecot: The mbox file format contains the SMTP envelope sender and transmission date in a FROM ... line preceding the RFC822 mail header and body. As far as I see at the moment, the IMAP protocol does not support transmission of that SMTP envelope data in either way, but confusingly uses the term „envelope” for a structure describing the RFC822 mail header. My question is, whether there is any way to retrieve the SMTP envelope through dovecot's IMAP anyway, maybe through some extension. regards Hadmut
