[Dovecot] Plugin question
by Valery Gorbunov 14 Feb '10

14 Feb '10

Hi All I needs to write plugin which converting messages by replacing entier message by one of parts of this message. In another words I need show part of multipart message instead entire message. Stream substitution in *mail->v.get_stream()* function gives incorrect results because mail indexed and cached before. Therefore I should wrap email during indexing too. something like: ----- struct index_transaction_context * it; it->ibox->mail_vfuncs->get_stream = convert_get_stream; ----- Is it enough or idea to replace mail stream by another will don't work anyway? Could you suggest how to show one mail instead another in Dovecot environment? Thank you Valery Gorbunov

[Dovecot] scalability
by Jonathan Tripathy 13 Feb '10

13 Feb '10

Hi Folks, How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz processor and 2GB of RAM would do a business with 600 users? This server will have a 100Mbps link to the net, however it will be access by the business using a couple of ADSL lines (Roughly 7Mbps each). This machine will also be running Postfix Your help is appreciated Cheers Jonny

[Dovecot] REPOST: mbox vs maildir
by Ashley M. Kirchner 12 Feb '10

12 Feb '10

Ignoring my previous message just for a second, I realized that my config wasn't correct. First the layout: ~mail/ ~mail/Drafts ~mail/Ashley-Feb09 ~mail/Others-Feb09 ~mail-Archives/ ~mail-Archives/2009/ ~mail-Archives/2009/Ashley/ ~mail-Archives/2009/Ashley/Ashley-Dec09 ~mail-Archives/2009/Ashley/Ashley-Nov09 ~mail-Archives/2009/Ashley/Ashley-Oct09 So I (now) have this for namespaces: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = maildir:~/mail-Archives:LAYOUT=fs inbox = no hidden = no list = yes subscriptions = yes } But when I'm in Thunderbird and I try to subscribe to anything that falls inside of ~/mail-Archives/ it won't work. I can browser all the way down to the folder, but I can't see anything within that folder. For example, consider the full path to the following 'Ashley-Dec09' mailbox: ~mail-Archives/2009/Ashley/Ashley-Dec09 In Thunderbird, when I hit 'Subscribe' I can browse down to '2009' and I can see 'Ashley', but I can't drill down into it and subscribe to 'Ashley-Jan09'. What am I missing here?

I still think that one possibility could be a Sieve script that would discard messages based on a message-ID cache like the procmail recipe does.

Dear All, I have created apache2 module that allows web users to authenticate against dovecot auth daemon. It connect to dovecot authentication client socket. Currently implemented mechanism is plaintext PLAIN. Currently there are no plans to support any other as only thing that i have created in apache module is "Basic" auth. Source code can be downloaded from; http://github.com/bmanojlovic/mod_authn_dovecot or tagged version v0.1 from: http://github.com/bmanojlovic/mod_authn_dovecot/tarball/v0.1 Currently built RPMS can be downloaded from OpenSUSE build service URL: http://download.opensuse.org/repositories/home:/bmanojlovic/<Distribution of choice> Please comment or raise issues if you think it is useful or full of bugs :).

[Dovecot] upgrade 1.0.15-2.3+lenny1 to 1.2.9-1~bpo50+1
by Stan Hoeppner 11 Feb '10

11 Feb '10

System: Debian 5.0.4 Lenny Kernel: custom 2.6.31.1 built from kernel.org source Dovecot: 1.0.15-2.3+lenny1 Available: 1.2.9-1~bpo50+1 Mailbox format: mbox Storage location: /home/$user/mail/ on ext2 fs Delivery: Postfix 2.5.5 local to /var/mail/$user As you can see Debian has a backport package of Dovecot 1.2.9 available to Lenny users, and it appears it is a big jump forward in terms of elapsed time and codebase. Debian ships Dovecot in a collection of 6 packages. I currently only use two, dovecot-common and dovecot-imapd. I'm guessing it would probably be wise to shutdown all my current Dovecot processes before starting the upgrade. Before I do this upgrade I figured I'd ask first to see if there are any gotchas or explosions awaiting me. Any warnings, hints, pointers anyone? Timo? Thanks. -- Stan

[Dovecot] fts squat -> webmail, fastcgi timeout: SOLR the answer?
by mailinglists＠belfin.ch 11 Feb '10

11 Feb '10

Hi I turned on fts squat to speed up full text searches over webmail. This works absolutely fantastic once the mailboxes are indexed. But when they are indexed for the first time I'm getting a fastcgi timeout after 30 seconds resulting into a internal server error on the webserver. In the background the indexing job is getting finished after 80 seconds for a 25k emails, ~300MB mailbox. Does solr allow user-offline indexing (no user interaction needed to kick on indexing) ? And the other question is, is there any mail user agent that would support server-side full text indexing and not create own indexes? Thanks, Philipp

[Dovecot] Purging a large folder... anything I need to be careful of?
by Dave 10 Feb '10

10 Feb '10

I've got a large message folder (about 40G in 'cur') that I need to empty to a more reasonable size. Oddly, my Thunderbird e-mail client only sees about 2.4G of that, and has "looped" a few times. What I mean is, I thought someone was cleaning the folder out, but Thunderbird apparently was actually just looping back to 0 every 4 gigs and starting to count up again Ha. But that's a sidenote. So, since Thunderbird apparently is not seeing all of the messages, what is the safest way to delete the files straight from the 'cur' folder? IS that safe? Will I mess up any of the dovecot indexes in any way?? Dave

[Dovecot] mbox vs maildir
by Ashley M. Kirchner 10 Feb '10

10 Feb '10

Ignoring my previous message just for a second, I realized that my config wasn't correct. So I have this for namespaces: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = maildir:~/mail-Archives:LAYOUT=fs inbox = no hidden = no list = yes subscriptions = yes } But when I'm in Thunderbird and I try to subscribe to anything that falls inside of ~/mail-Archives/ it won't work.

[Dovecot] Folders within folders ...
by Ashley M. Kirchner 10 Feb '10

10 Feb '10

Our mail setup is as follows: ~/mail/ - This contains single mailboxes (Drafts, Trash, and others) ~/mail-Archives/ - This contains a hierarchy of folders containing mailboxes For example, a tree of ~/mail/ would look like this: ~/mail/ ~/mail/Trash ~/mail/Drafts ~/mail/sent-mail ~/mail/My Stuff ~/mail/Important ~/mail/test/SomeFolder <-- this would never happen, but I have to account for it during our transition A tree of ~/mail-Archives/ would look like this: ~mail-Archives/2009/MyStuff/MyStuff-Dec09 ~mail-Archives/2009/MyStuff/MyStuff-Nov09 ~mail-Archives/2009/MyStuff/MyStuff-Oct09 ~mail-Archives/2010/MyStuff/MyStuff-Jan10 ~mail-Archives/2010/Important/Important-Jan10 All of that works, I can open up Thunderbird and browser/read/delete messages no problem. However, when I try to move that 'test' folder from ~/mail/ into ~/mail-Archives I get an error message: 'Can't rename mailbox to another storage type.' The same thing happens if I try to move any of the mailboxes in ~/mail/ to ~/mail-Archives/ . Is there a way to fix that? Our namespaces look like this: namespace private { separator = / prefix = "mail/" location = mbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } namespace private { separator = / prefix = "mail-Archives/" location = mbox:~/mail-Archives inbox = no hidden = no list = yes subscriptions = yes }

[Dovecot] Dovecot and duplicates
by Veikko "Wexi" Skurnik 10 Feb '10

10 Feb '10

Hi I'm having a problem setting up duplicate filtering on my mail server. I've set up the mail server with Postfix and Dovecot with virtual LDAP users, ClamAV virus scanning. The problem is that some of the virtual users use multiple e-mail addresses and postfix delivers emails sent to a user as many times as the user has email address entries in LDAP. I was wondering what would be the smartest way to get rid of these duplicates, they have identical message ID:s and a simple procmail recipe does the trick, however as I'm using dovecots deliver, procmail isn't the answer. Is it possible to use Sieve to do this, I've been googling around *a lot* and haven't found anything that would solve the problem... This is the procmail recipe that succesfully eliminates the duplicates: MAILDIR=/var/vmail :0 Wh: msgid.lock | formail -D 8192 .msgid.cache Or could another solution be to configure postfix to first receive the email, then let procmail do the duplicate filtering, then ClamAV does the virus scan and finally dovecots deliver delivers the message to the virtual user's mailbox? Any help will be greatly appreciated =) Wexi -- * Veikko "Wexi" Skurnik: +358(44)5288338 * * wexi(a)wexin.net Wexi@IRCNet * * Näyttämönkatu 4 B 12 33720 Tampere * * "Kosminen balanssi ei saa järkkyä" *

[Dovecot] Converting layouts
by Luciano Mannucci 09 Feb '10

09 Feb '10

Hello, I'm using dovecot 1.2.10 with mbox format (which implies layout=fs) and I would like to switch to maildir++ layout without changing format in order to implement subfolders for IMAP users. I understand that I should move the INDEX location to avoid some namespace conflict (it would be a good idea anyway: I'll move them on another disc :). Now I have mail_location = mbox:/var/spool/mailboxes/%u:INBOX=/var/spool/mail/%u in my /etc/dovecot.conf. I think it should become somethink like mail_location=mbox:/var/spool/mailboxes/%u:LAYOUT=Maildir++:INBOX=/var/spool/mail/%u:INDEX=/var/dovecot_indexes I'll have to rename folders for IMAP users, right? Is there some script that does just that? Some other needed black magic for .subscriptions? Thanks to all in advance, Luciano. -- /"\ /Via A.

[Dovecot] Problem with created ~/mail directory
by Chris Adams 08 Feb '10

08 Feb '10

If a user doesn't have a ~/mail directory and logs in, the directory is created for them. However, it is created with insecure permissions, 0770 (full group access). The problem is this bit in src/lib-storage/index/mbox/mbox-storage.c: #define CREATE_MODE 0770 /* umask() should limit it more */ The code then uses CREATE_MODE as an argument to mkdir_parents(), but mkdir_parents() overrides the umask setting and forces the requested permissions. There's no way to override this except to change the source code. It looks like the same thing is in dbox-storage.c and cydir-storage.c. This is with Dovecot 1.2.10. -- Chris Adams <cmadams(a)hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.

[Dovecot] LMTP in 2.0: concurrency, inet sockets
by Stefan Foerster 07 Feb '10

07 Feb '10

I didn't really have much time to look at the beta versions of dovecot 2.0 (apart from installing it once and migrating most of my current configuration, purely for testing purposes). An exciting new feature is the LMTP support. In the default configuration I have seen, that one only listened on a Unix socket - will it support network (inet) sockets, too? What about concurrent deliviers? As of now, when using the deliver LDA together with Postfix, you have to make sure that only one recipient is passed to deliver at a time, so for multi-recipient mail, the system might spawn a large number of processes (two per recipient, therefore two forks/execve calls). Is that limit still imposed with the new LMTP server? Stefan

[Dovecot] blocked for xx secs
by Andrew Hearn 06 Feb '10

06 Feb '10

Hello, Occasionally (a few times a day) we get batches of Warnings in the log such as: dovecot: Warning: chdir(/maildir/x.co.uk/users/y) blocked for 18 secs This tends to last a minute or so for different users. /maildir is a NFS mount, and I'm suspecting it's the NFS server being busy and dovecot having to wait. Other than replacing the NFS server with faster hardware is there anything else we can do? Indexes are local, and Maildir is on the NFS. Dovecot 1.2.5 using: mail_nfs_storage = yes mmap_disable = no NFS mounted as; /maildir on /.automount/a.diskless/root/mail type nfs (nosuid,nodev,noatime,vers=3,proto=tcp) TIA -- Andrew

[Dovecot] pop3 quick question
by Nikita Koshikov 06 Feb '10

06 Feb '10

Hello list, I have found imap_allowed option in dovecot which do exactly what I need, for imap. Is there something similar for pop3 protocol? The main goal for it - is to enable pop3 access to specific users. Or maybe dovecot have some 'pop3=yes' or 'imap=no' args to userdb/passdb sections ? I know future dovecot 2.* versions will support rewriting for protocols, but this is required for 1.2 branch.

Re: [Dovecot] mdbox compression
by Damon Atkins 06 Feb '10

06 Feb '10

ZFS has support for compression on the file system ( lzjb | gzip | gzip-N | zle ). gzip eats CPU even at levels as low as 3. From the zfs man page The lzjb compression algorithm is optimized for performance while providing decent data compression. You can specify the gzip level by using the value gzip-N where N is an integer from 1 (fastest) to 9 (best compression ratio). The cost of CPU to support compression (gzip) vs the Cost of Disk if mboxes are not compressed? The other interesting feature ZFS (OpenSolaris) has is de-duplication, it detects if the block which is about to be written, is the same as another block and instead of writing the block it puts a pointer to the already existing block, saving disk space. Only problem with this is you would need to filter out headers which are different even when the to/body is the same. Cheers

[Dovecot] mdbox compression
by Timo Sirainen 06 Feb '10

06 Feb '10

I was wondering if I should add compression support to mdbox one mail at a time or one file (~2MB) at a time. The tradeoffs are: * one mail at a time allows quickly seeking to wanted mail inside the file, but it can't compress mails as well * one file at a time compresses better, but seeking is slow because it can only be done by uncompressing all the data until the wanted offset is reached I did a quick test for this with 27 MB of my old INBOX mails: (note the -b option, so it doesn't count wasted fs space) mdbox/storage% du -sb . 15120350 . Maildir/cur% du -sb . 16517320 . % echo 1-15120350/16517320|bc -l .08457606924125705623 So, compressed mdboxes take 8.5% less space. This was with regular gzip compression with default level. With bzip2 -9 compression the difference was 10%. Any thoughts on if 8-10% is significant enough improvement to make seeking performance worse? Or perhaps I should just implement both ways.. :)

[Dovecot] Forcibly emptying a POP3 mailbox
by Răzvan Sandu 05 Feb '10

05 Feb '10

Hello, I've recently saw a discussion on this list, about a standardised way of emptying POP3 mailboxes on the server - but no solution came up. Please provide a suggestion for the following situation: - I am running a stock POP3 dovecot server, on Fedora 12 (dovecot version 1.2.9) - passwd-file authentication via /etc/imap.passwd - users are virtual, sharing the same UID/GID; - storage is in MailDir system; - for remote users, server is POP3-only, since the administrative policy says that every user should download his messages on the local workstation, then delete them from server immediately after succesful download. - IMAP is allowed only locally, in order to be used together via stock squirrelmail Web interface (for emergencies only) However, there are users that check the infamous „Leave a copy on the server” checkbox (or equivalent) in their mail clients, eventually adding „Delete messages after X days”. Since I have no direct administrative control on the clients, I absolutely need a way to forbid the above behaviour at server level, in order to enforce the policy. The server's HDD is meant to store received messages from reception to the first access only. Filesystem quotas are not an option in this scenario, since the UID/GID is the same for all virtual users. What I need is way to make sure that "cur" and "tmp" subdirectories are perfectly empty after the user downloads his mail. (I will also need a way to make sure that users using squirrelmail leave no populated "Sent" and "Trash" folders on server's HDD, but that's offtopic here). Could you please suggest a way to solve this ? Thanks a lot, Răzvan

Hello, Thanks a lot, but the problem here are not the IMAP users accessing the server via squirrelmail. Few people use this. What I mainly want to avoid are *POP3* users checking the „Leave a copy on the server” checkmark. I need a way of automatically performing the DELE command at server level, just after a POP3 user *succesfully* downloaded his messages via POP3... Thanks again, Răzvan

[Dovecot] postfix and dovecot on different systems - sasl request
by thomas polnik 05 Feb '10

05 Feb '10

Hello, until now I have use postfix and dovecot on the same server. Now I want/must split this both systems (server1 - postfix, server2 - dovecot). I used dovecot auth system for postfix ## snip ## smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth ## snap ## but this does not work, if dovecot is not running on the same server. I did not find any information in postfix/dovecot documentation, how I could solve this problem smart. My only idea, but it looks like quick and dirty solution: On the postfix system a small dovecot systems runs only for postfix sasl via /var/spool/postfix/private/auth. (Or I use saslauthd with sql or imap) The postfix system (on server 1) delivers mails via transport map to the dovecot system. On the dovecot system postfix delivers this mails i.e. via ## snip ## dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} ## snip ## to the mail boxes. Are there other ways, how I could solve this problem? My wish configuration: postfix sends the auth request via tcp/ip to the dovecot auth system and not via a socket. I use postfix 2.6 and dovecot 1.2.6. Best regards, thomas polnik.

[Dovecot] Fatal: chdir( ) failed: Permission denied
by Vallo Kallaste 05 Feb '10

05 Feb '10

Hi Dovecot fails to chdir() into users home directory giving the following error: Oct 9 16:43:49 jura dovecot: dovecot: Fatal: chdir(/a/home/mina) failed: Permission denied (euid=1118 0(mina) egid=11332(devel) missing +x perm: /a/home) Oct 9 16:43:49 jura dovecot: dovecot: child 14441 (imap) returned error 89 (Fatal failure) The reason seems to be that user primary group is "devel" and directory /a/home has ACL which gives execute permission only to the users in "domain users" group. Now the catch is that the user _is_ member of "domain users" group and is happily accessing his home directory over CIFS(Samba) for long time. Also, the user has no problem entering his home directory when using shell access. It just seems like the user lost membership of a bunch of supplementary groups. The group membership info is coming from M$ PDC via winbind and NSS. We have few users and can change the users primary group and/or relax the /a/home directory ACL, but overall this is not right. Shall I shut up or can we hope for a fix or at least explanation?

[Dovecot] Question re: storing non mail files via IMAP
by Charles Marcus 05 Feb '10

05 Feb '10

Hey Timo, I have a question regarding how dovecot might behave if a mail client (like, for example, Thunderbird) decided to store some of its config files on the IMAP server itself. Would there be a decent way of doing this with dovecot that wouldn't cause problems for other clients that didn't know about these files? Maybe there's a way to define a special folder that dovecot knows about at the top level of each users mail location that can be used for this kind of thing? All I'm thinking of are certain config related files, so they would be small, and would only be downloaded when they didn't already exist - ie, when someone adds their existing account to a new PC, the first time they logged in, TB could simply download all of the config files, restart itself, and voila, your pre-configured TB is ready to go...

I need mailutil in order to use the mbox to maildir translation routines that are posted in the Dovecot wiki, but there is no mailutil with the AIX image... mailutil is apparently built as part of Pine, and indeed I can see it in the build tree from my V4.6.1 Pine build, which I still have....OTOH, my version of Pine is not patched for maildir. Will the native pine mailutil work with mb2md or does it have be a mailutil built in a patched Pine :) tree?

[Dovecot] [RFE] A way to encode passwords in the /etc/imap.passwd file
by Răzvan Sandu 03 Feb '10

Hello, Is this the proper place to suggest an enhancement for the stock dovecot package ? The enhancement would be the following: For the time being, the dovecotpw utility offers a standardised way to interactively encode a user password in a certain scheme, say: dovecotpw -s CRYPT Enter new passord: Re-enter new password: etc. Given a *valid* /etc/imap.passwd file (passwd-file authentication), dovecotpw should be able to process it non-interactively and output another text file with all {PLAIN} passwords converted in the specified <scheme>, i.e.: dovecotpwd -s CRYPT if=/etc/imap.passwd of=/etc/imap.passwd.converted where /etc/imap.passwd.converted have the previously {PLAIN} passwords converted in scheme CRYPT. Passwords that were previously encrypted in other schemes than {PLAIN} shoud remain untouched. That will allow quick securing of old legacy /etc/imap.passwd files. Thanks a lot, Răzvan

[Dovecot] deny=yes in userdb
by Edgar Fuß 03 Feb '10

03 Feb '10

I would like deliver to reject certain users. Since supposedly deliver only uses userdb, not passwd, I can't use deny=yes for that. Or does userdb support deny=yes? Yes, I should rather reject them right in the MTA, but that currently takes too long to implement. Or how to reject gast* in postfix using nss authentication?

[Dovecot] Restore of individual mail files
by CoolAtt NNA 03 Feb '10

03 Feb '10

Hi. In order for restoration to work fine, I have to create a folder using the interface (e.g RounCube) which also creates the required structures. Then I copied the emailfile e.g xyz:s to /myrestoredemail/cur/ How do i properly create a folder with its structures(index,etc) without using the RoundCube web inteface ?

[Dovecot] disabling mail delivery for a user
by Frank Cusack 02 Feb '10

02 Feb '10

How can I disable mail delivery for a user yet still allow access to their mailbox from another account which their mail is shared to? If I put them in a userdb which has "deny = yes" that just disables their ability to login, yes? And they would still have mail delivered. I want to disable their ability to login AND bounce all mail delivered to them, preferably solely through dovecot configuration. I am using lda, obviously, for mail delivery. (I could configure the MTA to reject mail for them if there is no other option.)

[Dovecot] v2.0.beta2 released
by Timo Sirainen 02 Feb '10

02 Feb '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta2.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta2.tar.gz.sig I tried to keep the configuration and APIs compatible with v2.0.beta1, but unfortunately there were a few things that really had to be changed: 1. passdbs and userdbs have now a separate "driver" setting inside them. So for example if you had: userdb passwd { } You'll now need to use instead: userdb { driver = passwd } 2. Services now have default inet_listeners. You need to either remove your existing ones, or override the defaults by giving the listeners's name like shown in the new example master.conf. For example if you had: service imap-login { inet_listener { port = 1234 .. change it to: service imap-login { inet_listener imap { port = 1234 If you want to disable a default listener, you can set its port to 0. Some new features: - Added auth_verbose_passwords = no|plain|sha1. If authentication fails, this setting logs the used password. If you don't really need to know what the password itself was, but are more interested in knowing if the user is simply trying to use the wrong password every single time or if it's a brute force attack, you can set this to "sha1" and only the SHA1 of the password is logged. That's enough to know if the password is same or different between login attempts. - lazy-expunge: Support a single-namespace configuration. In this setup if mailbox has some expunged messages and then the whole mailbox gets deleted, they get merged into the same deleted mailbox. - protocol !imap { .. } adds configuration to all protocols except imap. - imap/pop3 proxying supports now async DNS lookups for hosts. There's a separate dns-client service doing the lookups using OS's own blocking resolver. - dovecot-config file changed in a way that it'll be easier to create external software linking against dovecot libraries. This made Pigeonhole's configure script a lot simpler. And of course there have been lots of fixes.

[Dovecot] proxy_maybe regex
by David Halik 02 Feb '10

02 Feb '10

Does anyone know if dovecot support regex lookups for proxy/proxy_maybe, rather than mysql/ldap etc? I've been comparing it with perdition to see which one might be better for us to do layer7 username switching. Perdition supports the ability to not have any auth/db looks, but rather just a regex file that parses the usernames as they come in and forwards to the particular machine on the same port. For example: username:host ^[a-d]: 192.168.xxx.1 ^[e-k]: 192.168.xxx.2 and so on... I didn't think this was supported in dovecot, but I wanted to check first. I think this is going to end up being what we use to avoid NFS problems. It's lightweight, drops into our current setup, and doesn't require a mysql database which adds another point of failure. -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] Want to have some users with Maildir, some with mbox
by Stewart Dean 02 Feb '10

02 Feb '10

Want to have some users with Maildir, some with mbox, as I migrate from mbox format to maildir over the space of a month. After everyone is converted to maildir, I'll change the mail_location in dovecot.conf. During the interim, can I use the Custom mailbox location script (at the bottom of the Mail Location DC Wiki page)? > if [ -d $HOME/.maildir ]; then > export MAIL=maildir:$HOME/.maildir > else > export MAIL=mbox:$HOME/mail:INBOX=/var/mail/$USER > fi > Questions: 1) What does explicitly specifying MAIL this way override? The dovecot.conf mail_location variable? 2) My mail_location var is defined as: mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcindx/%u and my prospective maildir INBOX and mail folder root is to be ~/Maildir. So would I change the above to: > if [ -d $HOME/Maildir ]; then > export MAIL=maildir:$HOME/Maildir:INDEX=/var/dcindx/$USER > else > export MAIL=mbox:$HOME/mail:INBOX=/var/spool/mail/$USER: > INDEX=/var/dcindx/$USER > fi Question 3: When converting existing users from mbox to maildir, should I delete the index contents?

[Dovecot] index location
by Dave Brenner 01 Feb '10

01 Feb '10

Greetings. We are testing with 1.2.9 and have found that with mail_full_filesystem_access set to 'yes', we cannot force indexes for folders under ~/mail to be stored in /var/dovecot/indexes/%u. /var/dovecot/indexes/%u/.imap/INBOX/dovecot.index* is created just fine, but everything else ends up in ~mail/.imap. If I change mail_full_filesystem_access to 'no', then all indexes are created in the expected location: $ ls -la /var/dovecot/indexes/blitz/ total 4 drwxr-xr-x 4 blitz popuser 512 Jan 25 11:46 . drwxrwxr-x 5 root popuser 512 Jan 22 16:16 .. drwxr-xr-x 3 blitz popuser 512 Jan 22 16:16 .imap drwxr-xr-x 3 blitz popuser 512 Jan 25 11:46 mail (I probably need to set the sticky bit for this, but for testing this is OK) We are setting the index location from /etc/passwd-dove: blitz:x:14267:500::/usr/users/dialups/blitz::userdb_mail=mbox:~/:INBOX=/var/mail/%u:INDEX=/var/dovecot/indexes/%u Is there a way to get this to function the way we'd like, with all indexes stored in /var/dovecot/indexes/u% ? My apologies if I missed an explanation about this in the list archive. Dave

[Dovecot] Extraneous information
by Michael M. Slusarz 01 Feb '10

01 Feb '10

Not technically a bug, but a small waste of bandwidth: it seems (at least as of 1.2.10) that if neither CONDSTORE/QRESYNC are enabled dovecot still sends HIGHESTMODSEQ info: a examine Testing.AAA * FLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded impflag0 impflag1 impflag2) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 309 EXISTS * 0 RECENT * OK [UNSEEN 5] First unseen. * OK [UIDVALIDITY 1225053009] UIDs valid * OK [UIDNEXT 387] Predicted next UID * OK [HIGHESTMODSEQ 136] Highest a OK [READ-ONLY] Select completed. I'm guessing this would only happen if using a client that supports QRESYNC (like IMP) and then switching later to a client that doesn't support.

[Dovecot] Not understanding namespaces
by Stewart Dean 01 Feb '10

01 Feb '10

I have been diligently reading about namespace in the DC doc and what I can find in Google. Like the blind men and the elephant, I see the nature of some individual bits of namespace, some syntax and the overall purpose (overriding defaults and providing extensions), but I don't see the whole thing and how it is used. I am looking to do some maildir testing in what is a mbox default system, so I thought to employ namespace to do so. I see that namespace(s) can be defined in dovecot.conf and I see that it can be defined in TBird (under ServerSettings, Advanced Account Settings), but it isn't clear to me how they are made to work together. Some questions: - Is it that you can define multiple namespaces in dovecot.conf and then specify which of these you use in the TBird server settings? - What is the syntax of the TBird namespace specification? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] sieve script
by Lampa 01 Feb '10

01 Feb '10

Hello, after qmail migration need convert some .procmailrc scripts. Found converter procmail -> sieve, but i'm not sure of quality of conversion. My script: --------------- if header :contains "from" ["user(a)domain1.tld", "user2(a)domain2.tld", "user3(a)domain3.tld"] { redirect "foo1(a)bar.tld"; redirect "foo2(a)bar.tld"; .... redirect "foo20(a)bar.tld"; } else { keep; } --------------- Converter script: --------------- require ["fileinto","regex","envelope","vacation"]; if envelope :comparator "i;octet" :contains "From.*(user@domain1.tld|user2@domain2.tld|user3@domain3.tld)" "" { redirect "foo1(a)bar.tld foo2(a)bar.tld .... foo20(a)bar.tld"; } if true { fileinto "$DEFAULT"; } --------------- Converter script is cannot be compiled. But it used other style envelope. So what is difference between envelope and header ? And there are some limits for redirect ? Thank you. -- Lampa

[Dovecot] sha-512 ... shadow blended with database
by WJCarpenter 31 Jan '10

31 Jan '10

The cryptic subject is the outcome of my looking into how to do a particular thing. I wonder if anyone else has solved this problem in a way that hasn't occurred to me. I'm using dovecot 1.1.11 on Ubuntu Server 9.10. I could consider upgrading to my own install of a newer dovecot if it made a difference to this problem. I have two populations of dovecot users. Some users have Unix accounts (with logins disabled), and so their password hashes are stored in /etc/shadow. These days, the default configuration for that is salted SHA-512. It's easy for me to change that scheme to something else if I want to, but the important fact is that I already have some users with passwords in salted SHA-512. The other population of users is purely virtual, and their password hashes are stored in a MySQL database in SHA-1 format (unsalted, but moving to salted wouldn't be a big deal). The database also has a column identifying the hash scheme, so SHA-1 isn't some assumption. I know that I have have multiple passdb in my dovecot config, but I'm looking to unify my two user populations and put them all in the MySQL database. As far as I can tell from the wiki, there is no SHA-512 in any version of dovecot. MySQL also doesn't have SHA-512. So, I don't see a way of reworking my password checking to accomodate the salted SHA-512 values currently in /etc/shadow. I'd prefer to not ask the SHA-512 users to update their passwords for this administrative reason if I can avoid it (but so far, that looks like the only answer). Any ideas?

[Dovecot] LSUB output format != LIST output format
by Martin 31 Jan '10

31 Jan '10

Hi, I have a problem with my hanging claws-mail. I first subscribed to their bug tracker, described the problem and before I pressed on submit in their bugtracker, I realized it might be a problem with dovecot. I'm using dovecot for internal purposes only (catching all my external boxes and storing locally): # 1.2.8: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-RELEASE-p5 i386 listen: *, [::] ssl: required disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_privileged_group: mail mail_location: maildir:~/.mails imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep lda: postmaster_address: postmaster(a)example.com sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login username_format: %Lu passdb: driver: pam args: session=yes dovecot userdb: driver: passwd args: blocking=yes socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 The mailboxes are on simple UFS2 file system. Here is what I get when listing subscribed folders, like claws-mail does: . LSUB "" "*" * LSUB () "." "Trash" * LSUB () "." "Queue" * LSUB () "." "Sent" * LSUB () "." "Drafts" * LSUB () "."

LIST "" "*" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Queue" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasChildren) "."

The folder name here does not have the dot at the end? Why is this happening? The RFC says the output should not differ, as far as I understood it. I think it might be the dot in LSUB causing claws-mail loop indefinitely when refreshing the folder structure. Annoying!! I hope, you can help me. Thanks in advance. -- Martin Sugioarto

[Dovecot] Recommended method?
by Brandon Lamb 30 Jan '10

30 Jan '10

Hopefully this isnt TOO general of a question. I have a raid server that runs dovecot and exports via nfs the maildir format store. I have 4 mail servers running exim that use dovecot to deliver over nfs I have been examing our entire setup and had the thought, would it be recommended to instead have another exim process running directly on the raid server and have my mail servers deliver mail to that rather than over nfs, if that makes sense? So mail would go from our postini frontend => mail cluster => final delivery via exim on raid server. Seems like this way I could make all the nfs config options go away and such. Thoughts?

[Dovecot] Pigeon hole sieve binaries and dovecot header install
by Mark Washenberger 30 Jan '10

30 Jan '10

Stephan, I've recently been playing around with packaging dovecot 2.0 and dovecot-2.0-pigeonhole, as well as the --enable-header-install configure options of both. This lead me to the following question. Should pigeonhole's sieve binaries rely on static libstorage / other dovecot libraries? It seems like they should instead use shared libraries, but I couldn't find a configure option to make this happen. That way, I could break my packages up like so: dovecot dovecot-devel libdovecot dovecot-pigeonhole dovecot-pigeonhole-devel And while pigeonhole/sieve might require libdovecot to run, it shouldn't require it to compile. Thoughts? I can provide a lot more detail about my compilation errors if you think its necessary.

[Dovecot] Does anyone know a good Dovecot hoster in europe?
by Johannes 30 Jan '10

30 Jan '10

Hi, though I am not sure this is the right place to ask, but I just try. I am looking for a better e-mail hoster providing me with a dovecot server (I don't want to do all the admin stuff and backup myself, if possible). I already googled a bit, searched the archives and had a look at dovecot.org but could not find an answer to this question. Since dovecot seems to get a fair amount of funding from finnish companies I thought there should be a good hoster among them. Any hints? Thanks Johannes

[Dovecot] Dovecot SSL issues
by Spyros Tsiolis 29 Jan '10

29 Jan '10

Hello all, successfully managed to make dovecot work with horde (http://www.horde.org) and another MTA (SMTP/POP3). I have this nagging issue with dovecot though (I suspect - it's dovecot and not the rest of the packages, please read on): There is this special page one goes, that check if everything is ok with all the relevant software running along Horde. It's a php file called "test.php". Now, this file shows almost everything that happens in the box. Here's a transcript of what shows when it comes to dovecot and SSL : --------------------------- * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAINCertificate failure for localhost: self signed certificate: /C=GR/ST=Kerkyra/L=Kerkyra/O=The Company Name/OU=IMAP server/CN=webmail.thecompanyname.gr/emailAddress=postmaster(a)webmail.thecompanyname.gr --------------------------- From what I understand, it doesn't like the certificate. However, I've followed a howto document step-by-step and did what is documented. Does anyone have any pointers on how to make secure imap for dovecot ? E.G. on ThunderBird, the settings are the following : Tools -> Account Settings -> Server Settings : Server Name : (the server or its ip address) Username : (the username) Port : (I've manually entered "993", because by default goes to "143") Security Settings -> Connection Security : SSL/TLS (again manually entered) CHECK_ON : Use secure authentication Now, if I click on "Get Mail" button on top of the TB window, I get a pop-up window with the following message : ------ Server : Location : <Servers' IP Address>:993 Certificate Status : This site attempts to identify itself with invalid information. Wrong Site : Certificate belongs to a different site, which could indicate an identity theft. Unknown Identity : Certificate is not trusted, because it hasn't been verified by a recognized authority. ------ After that, the users accepts the above by pressing ok twice. However, there's a third pop-up window with a message shown below : ------ You cannot log in to <servers' ip address> because you have enabled secure authentication and this serer does not support it. To log in, turn off secure authentication for this account. ------ Any help would be appreciated.. Thank you all for your patience, S. Tsiolis

[Dovecot] mdbox, dsync
by Timo Sirainen 29 Jan '10

29 Jan '10

I finally migrated my mails from mbox format to mdbox format using dsync: 1. Stop dovecot, wait a few seconds for processes to die 2. dsync convert mdbox:~/mdbox 3. Change mail_location to mdbox:~/mdbox 4. Check that no new mails arrived during conversion (alternatively I could have just run dsync again, but I decided not to test my luck) 5. Start dovecot After fixing a pretty bad bug in dsync and a couple of other unrelated bugs, everything seemed to work correctly and transparently. UIDs and everything was preserved as expected. I think I even feel my mail clients being faster than with mbox :) ~% du --exclude=.imap -bsh mail-old-mbox 707M mail-old-mbox ~% du -bsh mdbox/* 27M mdbox/mailboxes 704M mdbox/storage The reason why I'm giving -b is because without it, mdbox was a lot larger than mbox (734 MB vs. 710 MB). I guess this is because zfs internally decided to waste some space for the files. ~/mdbox/storage% ls -lS -rw------- 1 tss tss 13602413 2010-01-29 18:05 m.68 -rw------- 1 tss tss 10487382 2010-01-29 18:06 m.209 -rw------- 1 tss tss 7749964 2010-01-29 18:06 m.270 -rw------- 1 tss tss 7493010 2010-01-29 18:05 m.69 .. -rw------- 1 tss tss 2097246 2010-01-29 18:06 m.175 -rw------- 1 tss tss 2097213 2010-01-29 18:06 m.151 -rw------- 1 tss tss 2097173 2010-01-29 18:06 m.197 -rw------- 1 tss tss 2097163 2010-01-29 18:05 m.89 -rw------- 1 tss tss 1307164 2010-01-29 18:33 m.296 Total of 296 files. The reason why there are a few large files is because their last mail is huge. I guess in future mdbox should try to avoid doing that if it knows the mail's size beforehand. Actually I thought it already tried to do that.. Anyway, let's hope it doesn't now corrupt all my mails.

[Dovecot] dovecot auth feature request
by Frank Cusack 29 Jan '10

29 Jan '10

when i try to run dovecot for SASL support only, with literally just this configuration: protocols = none ssl = no auth default { mechanisms = plain login passdb passwd-file { args = /etc/dovecot/passwd } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 } } } I get this: Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or directory Since, in this configuration, SSL doesn't have meaning, dovecot shouldn't be looking for any cert file. Easily fixed with "ssl = no" but that shouldn't be required. -frank

[Dovecot] mailbox format w/ separate headers/data
by Frank Cusack 29 Jan '10

29 Jan '10

In the future, it would be cool if there were a mailbox format (dbox2?) where mail headers and each mime part were stored in separate files. This would enable the zfs dedup feature to be used to maximum benefit. In the zfs filesystem, there is a dedup feature which stores only 1 copy of duplicate blocks. In a normal mail file, the headers will be different for each recipient and the chances of the content of the message being able to be dedup'd are close to zero, because the differences in header length changes the block boundaries for the rest of the message. But if each mime part is stored in a separate file, you get massive compression "for free". -frank

[Dovecot] Courier-to-Dovecot-migration: Outlook downloads all Mails again
by Werner 29 Jan '10

29 Jan '10

Hi everybody, I'm currently playing through the migration from Courier to dovecot. I've converted the User's Maildir with 'courier-dovecot-migrate.pl'. Outlook 2003 is configured to access the Mailbox via POP3, the option "Leave a copy of messages on the server" is activated. But: after the migration Outlook 2000 redownloads all mails again :-( Could it be, that Outlook 2000 "thinks" (after changing the POP3/SMTP-Server in the Outlook configuration pointing to my testsystem) this is a new system and starts to download the messages again? If so, Outlook 2000 won't download all messages again if we do the migration because POP3/SMTP-Server remains the same. Can anybody confirm this? We do not experience this issue with Thunderbird for example. Thank you, Werner

[Dovecot] virtual users with mysql
by Andre Hübner 28 Jan '10

28 Jan '10

Hello List, we use in our system cryptical Usernames for dovecot etc. and authenticate users against shadow/passwd User abcde is loging in and gets data from /var/spool/mail/abcde and /home/popuser/abcde Now we want to make it possible that users can log in also with emailadresses. I tried dovecot-mysql authentication which works fine but i do not find a way to use 2 different login-formats in my queries. login with abcde and also testname(a)example.com should return ok and lead to /var/spool/mail/abcde. Is this possible or i have to make a decision which format to use? Thanks, Andre

[Dovecot] Dovecot 2.0 authentication will not work with Exim [patch]
by Kirill Miazine 28 Jan '10

28 Jan '10

Just a notice to those of you who use Dovecot authentication with Exim. In Dovecot 2.0 authentication server will send a new keyword, COOKIE. This will cause Exim to abort it's authentication request. I submitted a bug and patch to Exim to fix this, the patch is here: http://km.krot.org/code/exim-dovecot-1.1.diff BR, Kirill

[Dovecot] virtual mailbox / INTHREAD use case, issues, questions
by David Abrahams 27 Jan '10

27 Jan '10

For over a year now, I've been trying to acquire the ability to review the thread history of a message in my INBOX while still deleting messages as soon as I believe I'm done with them. Suddenly I'm gratified to see that several approaches have been right under my nose all along! One is the INTHREAD imap extension, which I see is implemented by dovecot. Another (related) is dovecot's virtual folders. When I saw the GMail-style "conversation view" described at http://wiki.dovecot.org/Plugins/Virtual I was elated, so I tried it out, with exactly that configuration (almost -- my separator is '.'). I ran into several problems (using Dovecot 1.2.8 with http://hg.dovecot.org/dovecot-1.2/rev/9cccb8617820 applied): 1. I had to manually create the virtual folder for all my users or they couldn't access their mail at all. Is this fixed in 2.0? 2. My users were getting errors when accessing via POP3. The possible meaning of such a virtual folder under POP3 is lost on me, but I had to enable the virtual plugin for that protocol too. I think that should at least be in the documentation, or better yet the requirement should that it be enabled for POP3 should be dropped. 3. I couldn't get the virtual "conversation view" inbox to show any messages. But maybe that's because of a possible issue I describe below with x-mailbox 4. At some point I ended up with an empty mailbox called "private.virtual" --- I have no idea how. Probably user error. 5. The "all" virtual mailbox would only show 89 messages. I switched it to be a mirror of my "archive" mailbox and the number started to look more reasonable. This could be the "lots of mailboxes" bug describe in http://dovecot.org/list/dovecot-news/2009-December/000145.html 6. I got the impression that looking at the virtual INBOX didn't cause the "all" mailbox to be updated, which I'd guess that it should be. 7. I tried to create an IMAP search, rather than a virtual folder, that looked for x-mailbox INBOX header like the virtual folder does. It too came up empty. It doesn't exactly surprise me because I don't see an x-mailbox header in any of these messages. In fact, I can't find one in /any/ of my messages. When I look for a description of the x-mailbox header, I don't find much information on where it comes from or what it represents. http://www.dovecot.org/list/dovecot/2009-June/040619.html seems to indicate it's synthesized by the server. If it's really supposed to represent the message's "original" mailbox as implied by http://wiki.dovecot.org/Plugins/Virtual then I'm not sure what that means for messages that are filed twice by sieve and never moved. Lastly, I want to report that for me, the speed of these IMAP searches doesn't begin to approach what I can do with mairix if I want a message's entire thread. I'm happy to use mairix, although it would be nicer not to duplicate that capability if it's already in the server. But it needs to be fast. Is there something I can do to make it go faster? Thanks in advance for any advice, hints, fixes, workarounds, etc. -- Dave Abrahams Meet me at BoostCon: http://www.boostcon.com BoostPro Computing http://www.boostpro.com

Looks like my bugfix exposed yet another bug. Your script worked previously because the removeflag command did not work properly. With 0.1.15 I fixed the removeflag command, thus breaking your script. The essence of the bug we face now is that for the deprecated imapflags extension (that you are using now) only the flag state at the end of the script is used for storing messages. This is now fixed: http://hg.rename-it.nl/dovecot-1.2-sieve/rev/a890258aa5a9 You can work around this issue by substituting "imapflags" with "imap4flags" in the script above. I've added some proper tests to the test suite to prevent this problem from re-occuring in the future. Regards, Stephan.

[Dovecot] STATUS command and total/read message count
by Florian Effenberger 27 Jan '10

27 Jan '10

Hello, I'm running Dovecot 1.0.15 with Thunderbird 3.0.1. TB can query folders for messages in two ways: Either by using the STATUS command, or by opening the folder (don't know the respective IMAP commands, sorry...). Querying via opening the folder is reliable, but via the STATUS command, only new/unread messages are shown. If I want to have the total number of (unread) mesages in a folder, I have to manually open it, so the headers are loaded. Is this a Dovecot issue, or a problem with Thunderbird? In other words: Does the STATUS command only return new/unread messages, or can this be configured on the server side? Thanks, Florian

[Dovecot] Plugin
by Alex Baule 27 Jan '10

27 Jan '10

Hello Everyone... Some time ago, i send some questions about plugins and concat 2 file handles. So, there is another questions about this. Timo Sirainen send to me this modification, in src/lib-storage/index/maildir/maildir-mail.c struct istream *full_input[3]; full_input[0] = i_stream_create_fd(fd, 0, TRUE); full_input[1] = i_stream_create_fd(fd1, 0, TRUE); full_input[2] = NULL; input = i_stream_create_concat(full_ input); This is necessary because my Header and Body is splited. This modification works fine. My question is: There is a way to do this with a plugin ? I dont know how to implement this in a plugin, because i dont know what is the hook to change the maildir_open_mail functions. (this is the function with the modification above) . Another question is: There is a seek function, in dovecot, and in zlib plugin, it is rewrite by another function, that use the "gzseek" to do the seek. My splited body will be encrypted, and the crypto no have seek, because the message will be encrypted. (if i open the message, decrypt and seek to some position, maybe work). The seek function is really necessary to IMAP and maildir ?

[Dovecot] Are Mail files in /Maildir/cur & /Maildir/.Sent read-only ?
by CoolAtt NNA 26 Jan '10

Hi ALL... I want to know if the files in /Maildir/cur & /Maildir/.Sent are modified by dovecot. I have a script which calculates the age of the mail files. I think that if they are continuously modified by dovecot I won't be able to calculate the age of the files. Can Anyone plz advise on this....

[Dovecot] read-only dovecot-uidlist
by Cor Bosman 26 Jan '10

26 Jan '10

Hi all, i just investigated a user complaint and found a read-only dovecot-uidlist. Since dovecot couldnt write it, the process failed. Users can not reach this file, so how this became readonly is beyond me. Must be something in dovecot. Maybe an older bug? Doing a search now for more readonly uidlist files, but that'll take a few hours. Cor

[Dovecot] dovecot-antispam for dovecot 2.0?
by Adam Seering 26 Jan '10

26 Jan '10

Hi, Just wondering, is there a development version or the like of the dovecot-antispam plugin, that works with the Dovecot 2.0 beta? I'm starting to poke at the new version (mdbox looks really handy for my use case); I'm also starting to play with dspam, but I'm finding it annoying to train dspam without it having direct access to my (rather-large existing) spam folder... Thanks, Adam

26 Jan '10

Hi ALL... Am working on a solution to backup maildir mailboxes using rsync. All mailbox directories are mirrored on another machine. I need advise regarding restore of the INBOX & SENT files from the backup. For e.g , [1] Can I just copy "file-x-y-z" from /Maildir/cur to restore it on /Maildir/cur on the mailserver. [2] Can I do same for SENT emails ?
