[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

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] read-only dovecot-uidlist

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

[Dovecot] acl flag to limit imap_acl based acl changes
by Amon Ott 26 Jan '10

26 Jan '10

Hi all! I have tried the imap_acl plugin with 1.2.9 today, but was not able to limit acl changes for those mailboxes where acl changes should be forbidden. http://wiki.dovecot.org/ACL says that "a" or "admin" covers "Administration rights to the mailbox". However, removing "a" from owner acl (using "lr") does not help, the user can still change all acl flags for all users with imap. Write accesses to mails are forbidden as they should. Is this intended or a bug? We would like to give all users the ability to use ACLs through IMAP, but the current behaviour endangers our read-only mail archives.

[Dovecot] Released Pigeonhole Sieve v0.1.15 and ManageSieve v0.11.11 for Dovecot v1.2.10
by Stephan Bosch 25 Jan '10

25 Jan '10

Hello Dovecot users, It's been a while since the last Pigeonhole Sieve and ManageSieve releases. That is why this release includes quite a few changes. Most interestingly, the include extension is updated to match the most recent specification, the Sieve interpreter now includes plugin support and ManageSieve now has support for enforcing quota on the size of scripts, the number of scripts and the space the scripts occupy on disk. Other than that, quite a few small bugs were fixed. One of which was in the i;ascii-numeric comparator. If one of the matched strings did not start with a digit, the comparator would always yield a 'less-than' result. In stead it should have considered the string starting with the non-digit character as having a positive infinite value. Elsewhere in this list, Julian Cowley pointed out that negative values also start with a non-digit character, which some people may not have understood (i.e. i;ascii-numeric works only on unsigned values). The bug fix in this release could therefore change result of certain misconceived (and probably spam-related) Sieve rules, so watch out! I started work on the spamtest(plus) and virustest extensions. These are implemented for the most part, but their configurability needs quite a bit more work. Changelog Sieve v0.1.15: * Enotify extension: - Adjusted notify method API for addition of new notification methods. - Set default importance level to 'normal' (was 'high'). * Include extension: updated implementation towards most recent specification (all should be backwards compatible): - Implemented global variables namespace. - Global command may now appear anywhere in a script. - Implemented script name checking using the requirements specified in the ManageSieve draft. - One issue remains: ManageSieve currently requires included scripts to be uploaded first, which is not according to specification. * Changed envelope path parser to allow to and from envelope addresses that have no domain part. + Added preliminary support for Sieve plugins and added support for installing Sieve development headers. + Started work on the implementation of the spamtest, spamtestplus and virustest extensions (unfinished). + Deprecated notify extension: implemented denotify command. + Variables extension: added support for variable namespaces. + Added configurable script size limit. Compiler will refuse to compile files larger than sieve_max_script_size. + Testsuite changes: - Added support for changing and testing an extension's configuration. - Added a command line parameter for copying errors to stderr. - Fixed a bug in the i;ascii-numeric comparator. If one of the strings started with a non-digit character, the comparator would always yield less-than. - Imap4flags extension: fixed bug in removeflag: removing a single flag failed due to off-by-one error (bug report by Julian Cowley). - Improved EACCES error messages for stat() and lstat() syscalls and slightly improved error messages that may uccur when saving a binary. - Vacation extension: fixed typo in runtime log message (patch by Julian Cowley). - Fixed use of minus '-' in man pages; it is now properly escaped. - Fixed parser recovery. In particular cases it would trigger spurious errors after an initial valid error and sometimes additional errors were inappropriately ignored. Changelog ManageSieve v0.11.11: * This release contains adjustments to match changes in the Sieve API. This means that this release will only compile against Pigeonhole Sieve v0.1.15. + Implemented ManageSieve QUOTA enforcement. + Added MAXREDIRECTS capability after login. + Implemented new script name rules specified in most recent ManageSieve draft. - Fixed assertion failure occuring with challenge-response SASL mechanisms. - Made configure complain about trying to compile against installed Dovecot headers alone. - Fixed compile warning for compilation against CMUSieve.

[Dovecot] Delete messages with archivemail
by gstyle 25 Jan '10

25 Jan '10

Hi, I have set up a dovecot imap server (Version 1.0.15 on Debain Lenny). Until know I used courier. Every night I run a script calling archivemail ( http://archivemail.sourceforge.net/) to delete all messages in the Spam folder that are older than 30 days archivemail deletes the files directly in the Maildir folder. I am not using IMAP for this (cause I don't want to store the passwords in plain text). I know that dovecot uses index files to speed up Maildir access. Will there be any problems with the index files when I delete the old spam like this? Cheers Mario

[Dovecot] pop3+leave messages on server
by Papp Tamas 24 Jan '10

24 Jan '10

hi All, I have a srange problem. Before dovecot there was a courier imap and it worked just fine. The client(s) are the same then before, so I think, this is an server side problem. I have a user with Outlook and he uses pop3 and leaves messages on server. Sometimes the messages get downloaded again, when he starts the outlook. Not all, but 7-9 hours back. uidl format is like it's suggested: pop3_uidl_format = %08Xu%08Xv Any idea, what's wrong and what I can do? Thank you very much, tamas

[Dovecot] strange behaviour with seen/unseen messages in virtual folders.
by Matthias Rieber 24 Jan '10

24 Jan '10

Hi, I've a virtual folder that contains unseen messages. When I mark the message and expunge the folder, the message should disappear. This works as expected in alpine. Alpine uses the following commands: 06000010 STORE 1 +Flags (\SEEN) 06000020 EXPUNGE Using roundcube mail, the message wont disappear, when I perform the same steps. RoundCube Mails sends: flg UID STORE 445 +FLAGS (\Seen) exp1 EXPUNGE But the message doesn't dissapear. But I can expunge it with alpine, as long as the folder contains one message. If it contains more messages, some or even all messages won't disappear. When I mark them as unseen/seen in alpine, I can expunge them with alpine. The expunge command send by roundcube mail never expunges any seen message in the unseen folder. Whether it was flagged as seen by alpine nor roundcube mail. kind regards, matthias

[Dovecot] Need simplest method for providing alternate mail location
by Stewart Dean 24 Jan '10

24 Jan '10

I am looking to migrate my DC V1.2 from mbox to maildir format....and want to do this in stages, user group by user group rather than in one horrendous fell swoop....since I'd rather fell things didn't happen. Since I'm running sendmail/procmail, I can change the ~/.procmailrc to change the writing of the INBOX, but the IMAP mail location access info is knottier when one wants to do things a bit at a time. Setting aside for now the matter of converting existing folders, I will be moving: = from a mbox setup with the INBOX in /var/spool/mail/<userid> and the folders in ~/mail = to both in ~/Maildir (unless someone has better ideas) It seems that one could: 1) Change the namespaces in the client...but this is not feasible, because it would means going out to all my 4000+ users desktop and modifying them. 2) Having some sort of db to tell DC it a mail_userdb extra field and override the mail_location in dovecot.conf 3) Perhaps waiting for DC v2.0 which will have this architected in. A) Is there any sense the v2.0 will be coming Real Soon Now and will fulfill #3? B) What's the simplest way to implement #2? I would really rather not install MySQL on my mail server and have all the overhead of installing and managing it when all I need it for is a temporary resource to tell DC where things are until the switchover is complete and Maildir is the default. Is it feasible to do this with an additional flat file in the /etc/passwd mode with some extra fields tacked on that is *only* used for mail location info? Or some other and simple way? My apologies if this is a Stupid Question............. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] SpamAssassin and i;ascii-numeric comparator
by Julian Cowley 24 Jan '10

24 Jan '10

Hi Stephan, I noticed that you changed i;ascii-numeric comparator recently (<http://hg.rename-it.nl/dovecot-1.2-sieve/rev/17fb38aee85f>) to correct a small bug. I have an interest in this because I use the comparator to check for SpamAssassin scores. Before the fix, this was all that was necessary to check for scores above a certain value: header :value "ge" :comparator "i;ascii-numeric" "X-Spam-Score" "5" Since SpamAssassin includes negative scores and the i;ascii-numeric comparator doesn't recognize negative numbers, all negative scores are actually treated as positive infinity after the fix. Of course, this means mail which has a negative score then gets counted as spam. Now an additional test is necessary, something like this: allof(not header :matches "X-Spam-Score" "-*", header :value "ge" :comparator "i;ascii-numeric" "X-Spam-Score" "5") I thought I'd mention this because other people may get affected by this once 0.1.15 comes out. Here is a patch that makes further tests for the comparator between numeric and non-numeric values. Hope you can use it. -=- julian

[Dovecot] how to create maildir on local mail delivery
by Sebastian Logar 24 Jan '10

24 Jan '10

Hi! I am using Dovecot 1.0.10 with LDA/postfix option reading user data from ldap, but the problem would be nonexistent maildir. Connection with ldap should be fine since reading proper maildir folder. Is it possible to auto creating maildir folders even on received mail since the you can auto create when user login with mail_executable scripts as it's seen from configuration I am doing for pop3 and imap.

[Dovecot] feature question: local delivery from SMTP
by Phil Howard 23 Jan '10

Does Dovecot really need a separate MTA for inbound mail? Or can it receive SMTP directly if there is no forwarding to do? What about spam/virus filtering in that case? -- Phil Howard KA9WGN - ka9wgn(a)gmail.com

[Dovecot] Mail process plans: multiple connections in a process + idle processes
by Timo Sirainen 23 Jan '10

23 Jan '10

Maybe for v2.1: imap and pop3 processes can currently handle multiple connections, but they're assigned pretty much randomly to processes. It would be better if it was possible to: a) Require that a process handles only a specific user's connections b) Require that a process handles only a specific UNIX UID's connections (e.g. if each domain has a separate UID) c) Prefer to put user's connections to same process, but don't require it. To do this, there needs to be a process between imap/pop3-login and imap/pop3. Let's call it imap/pop3-tracker process (or aggregator? or any suggestions?). This process accepts all connections coming from login processes when they've finished authenticating a connection. Internally it figures out if the connection should go to a new or an existing process. It keeps track of username -> { mail_process[], cookie (see idle processes below) } mail_process -> { unix_socket_fd, connection_count } So there's a connection to each mail process. This connection is used to send connection fds for the process to handle. It's also used to receive notifications when a connection is closed. The mail process sockets could also be used to communicate to a specific process. For example doveadm could use this in future to ask what a specific user or process is currently doing, by connecting to imap-tracker, which forwards the request to wanted process(es). The above isn't really anything new, just a more specific plan about what I had been thinking for a long time. A new and more interesting idea is to gather IDLEing imap connections under a few imap-idle processes: When a connection has been IDLEing for a few minutes (or something), and there's no special state in the connection (e.g. CONTEXT=SEARCH searches), the connection could be moved to a separate imap-idle process that simply waits for something to happen. When something does happen, it'll move the connection back to imap process, which restores state and continues. The idea would be to reduce the number of idling imap processes that are wasting memory. The state that needs to be saved and restored is: - selected mailbox name, GUID, UIDVALIDITY (for reliably selecting back the original mailbox, or reliably fail if it's gone) - flag: mailbox is EXAMINEd, not SELECTed - highest seen modseq - UIDs of \Recent messages - SEARCHRES extension: last saved SEARCH result - List of keywords that had been advertised in FLAGS/PERMANENTFLAGS reply to client. Or probably MD5 sum of it would be enough. If MD5 had changed, the list would be re-sent to client. - connection fd - paths that are being monitored with [id]notify/kqueue Connection is moved back when a) new command is received from connection fd, b) one of the monitored files changes. The connections are moved back via imap-tracker process, by sending the saved state along the request. For security there's a per-user security cookie (128 bits of randomness), which is sent to imap processes, and when restoring connection from imap-idle, the request must provide the correct cookie or imap-tracker fails the login. (Normally new post-login imap/pop3 connections can't be created without having authenticated first via dovecot-auth. They verify it.) So when connection comes back, imap process opens the mailbox based on saved information. If this fails for some reason (e.g. mailbox deleted), client gets disconnected. Next Dovecot gets a list of changes to mailbox since the saved modseq, and based on that sends the missing FETCH, EXPUNGE, EXISTS and RECENT events. Again if it somehow fails, the client gets disconnected. At least initially this would only be done for connections that are running IDLE command, because non-IDLE connections are a lot more difficult to restore to their original state. This is mainly because if a message gets expunged, it's still visible to the connection until it issues a command that allows sending EXPUNGE event. To handle that, there would have to be code that allows building a view of mailbox where there are some expunged messages. Also it can be difficult to find out the expunged messages' flags, unless they're also part of the saved state.

[Dovecot] format of file dict
by Frank Cusack 22 Jan '10

22 Jan '10

For shared (between users) mailboxes, I am using a file dict. plugin { acl_shared_dict = file:/etc/dovecot/acl_shared_dict/shared.db } What is the format of this file? I would like to manage it directly rather than have SETACL update it. I see lines which describe a sharing entry (the format of those looks obvious) but also lines with just a '1'. Do I just need to separate entries by lines with just '1' in them? -frank

[Dovecot] Thinderbird+delete+move to Trash folder
by Papp Tamás 22 Jan '10

22 Jan '10

hi All, I have a problem, which makes me headache. I can't find out, what is the problem. I have a mail szerver, which works just fine as expected, TB move messages to trash folder after I delete it, and they are moved. I have an other server. If I delete a message, it doesn't move to the Trash folder. As deleted_to_trash plugin is installed, if I only mark messages as deleted, they are moved to thee Trash folder and also with Outlook works well. It's like when a messages is deleted from TB, the message get moved to the Trash folder, and it's expunged(?) at the same time. Is it possible? Could you help me? The system is Ubuntu 9.04 with docecot 1.2.5-0~auto+0 from http://xi.rename-it.nl/debian/, but builded by myself for x86_64. Thank you, tamas

[Dovecot] Modifying the underlying maildir externally (webmail, replication)
by Attila Nagy 22 Jan '10

22 Jan '10

Hello, I have a setup where there are multiple maildir users, one of them being the pop/imap server itself, the others are for example a maildir capable webmail and message replication. I would like to evaluate Dovecot, but I wonder how would its binary indexes and logs fit into this picture. After running through http://wiki.dovecot.org/IndexFiles I'm not sure how well would Dovecot work with other programs modifying the maildirs (adding, deleting, moving messages, folders etc). The "Main index" section says "The index file is synchronized against mailbox only if the syncing information changes.", where syncing information consists or cur and new directories' timestamps. Does that mean I am safe there? The cache file is hopefully just a cache, so it won't contain information from messages which are inserted or moved by an external program, and I assume Dovecot fetches the message lists and other information from the main index, which seems to be OK. The transaction log is for the main index, so if the latter is OK, the former should be OK too. http://wiki.dovecot.org/MailboxFormat/Maildir talks about MUAs and there nothing scary can be found, except for some temporary conditions, where the changes won't propagate to Dovecot in real time, but it's OK. Are the above right, and can Dovecot use its indexes and caches safely with others using the same maildirs? Thanks,

[Dovecot] Files Moving From /New to /Cur
by Tony Rutherford 22 Jan '10

22 Jan '10

Using Dovecot 1.2-9 with Maildir and layout=FS. We have our own delivery pushing messages to the /new and then /cur folder eventually. When I have an IMAP client attached, there is apparently some sort of race going on. I believe that Dovecot is moving files from /new to /cur (and renaming them) before our own delivery gets the job done. This is causing a problem for us. Is there a way to disable this in Dovecot? I have the LDA section commented out of the config file..so I don't think that's in play. Bottom line is that I don't want Dovecot to move any files around whether an IMAP client is attached or not (except for handling the IMAP COPY/APPEND). Regards, Tony

[Dovecot] Conditionally use a sieve script with deliver?
by Kārlis Repsons 22 Jan '10

22 Jan '10

I found a post in this list [0], which says sieve scripts can be used to deliver mail as read. However, can it be done somehow conditionally, I mean, with a direct or indirect switch for deliver? For a nonexistent example, it would be simply < | deliver -m path/to/maildir -r > or maybe an environment variable could be exported to deliver sieve and checked there? (Still not sure if sieve can replace maildrop in my case, however, using it with dovecot creates various problems with interoperability; but perhaps I can just add those imap4flags like "\\seen" myself to the message with maildrop and avoid mess with sieve at all?)

[Dovecot] IDLE timing issue - dovecot or fetchmail issue?
by Matt Doran 22 Jan '10

22 Jan '10

Hi guys, Thanks for the great product. We've used dovecot for ages as our internal mail server and it works great! I've recently started using fetchmail 6.3.9 (with IDLE enabled) to download mail from our ISP (Pair networks). The ISP is running Dovecot 1.1.16. I am unable to get the info about the dovecot config at this time. The IDLE support in fetchmail allows us to deliver mail near instantaneously without the need to poll (which is what we did previously using POP3). However I've noticed an issue where if 2 mails are delivered in quick succession fetchmail will only download the first email, and the second will not download. If I then send in another test email this triggers the download of 2 emails (the original that wasn't downloaded and the test email). Now I'm wondering whether the issue lies with Dovecot (e.g. a timing issue), or is it fetchmail that isn't implementing the IDLE/download properly. I've attached the output of a fetchmail session showing this problem in action (I've added some annotations to this file starting with >>>>>). The sequence of events are: * Start fetchmail with IDLE enabled * Send 2 emails in quick succession. * Dovecot notifies of the new message * Fetchmail downloads the message * Fetchmail initiates a new IDLE * Then nothing more is delivered. :( * I then send another email, which triggers the 2 to download. I don't know enough about IMAP to understand whether the problem lies with Dovecot or Fetchmail. Hopefully an IMAP expert will be able to see from the attached IMAP session.

[Dovecot] IMAP only for some users or via webmail
by Federico Tomasczik 22 Jan '10

22 Jan '10

Hello! First, sorry for my English... I'm a newbie with Dovecot and I have some questions, I'm testing Dovecot 1.1.11 in a virtual machine. I wish in the future, migrate this to a real server. Ok, but i need this: 1) A group of users can use IMAP or POP3. 2) The others, only can use POP3. But, this users can use IMAP only with a webmail (the webmail is in the same server that Dovecot) It is possible? How? Thanks! Federico Ch. Tomasczik

[Dovecot] nologin in auth proto version 1.1
by Kirill Miazine 21 Jan '10

21 Jan '10

I notice that the nologin parameter for the AUTH command is gone in version 1.1 of Dovecot Authentication Protocol. nologin was added in 1.1, so that authentication client could indicate that there will be no subsequent master requests to retrieve user info. Could we have nologin back please? Kirill

[Dovecot] Maildir and IMAP keywords
by Per-Erik Persson 21 Jan '10

21 Jan '10

When a user in thunderbird toggles some flags like junk, spam or something similar dovecot appends these flags form a-z to the end of the file in maildir. I have another application that also access the maildirs which gets really upset with these flags and ignore those emails. Are there any other way for dovecot to store these flags to make it compatible with other softwares?

[Dovecot] Migration from Courier to dovecot
by Werner Detter 21 Jan '10

21 Jan '10

hi list, I've just registered to the list, so please be tolerant ;) I'm currently in the process of planning the migration from courier to dovecot as POP/IMAP-Server. I'm migration from Courier 0.58 (Debian-Etch-packages) to Dovecot 1.1.13 (Debian Lenny Backport). The conversion of the Mailbox from Courier to Dovecot will be done with "courier-dovecot-migrate.pl"-script[1], which works fine. However after running "courier-dovecot-migrate.pl" the Courier-Files still remain in the Maildir. Can i just delete those Courier-specific-files or does dovecot need them somehow (do you normally get rid of these after conversion)? It's about these files: courierimapacl courierimapsubscribed courierimapuiddb courierpop3dsizelist And those directories: courierimaphieracl courierimaphieracl Can i simply delete those with "find" ? Furthermore: is it possible to convert back from Dovecot-Format to Courier-Format? Thanks in advance, Werner [1] http://www.dovecot.org/tools/courier-dovecot-migrate.pl

[Dovecot] MUA notifications on new mail in a new folder?
by Kārlis Repsons 20 Jan '10

20 Jan '10

If deliver gets run with a non-root userid like this: < | deliver -m path/to/NEWmaildir >, I wonder, is a connected IMAP MUA automatically notified, that the new message has arrived in the new folder? As I see from some experiments with Thunderbird, it has no problems with immediate notifications of new mail in previously existing folders, however, it has problems with the case of new folder.

[Dovecot] outlook 2007 can't see public folders more than 1 deep
by Frank Cusack 20 Jan '10

20 Jan '10

dovecot-1.2.9 I have a public folder using ACLs to determine who can access it. namespace public { separator = / prefix = shared/ location = maildir:/var/maildir/shared subscriptions = no } Outlook 2007 can't see any folders except at the top level. It can create them just fine, but can't see them after quit and restart. For example, I can create the folder shared/foo/bar but on restart outlook only sees foo as a folder without subfolders (no + to expand it) and doesn't see bar anymore. In fact I can delete the folder foo in outlook and then BOTH .foo and .foo.bar directories are removed on the server. When you click on foo, the error message in the mail pane is "Cannot display the folder. The folder 'foo' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure not to append '/' to its name as you create it." -frank

[Dovecot] md5_verify(...): Not a valid MD5-CRYPT or PLAIN-MD5 password
by BaQs 20 Jan '10

20 Jan '10

'afternoon list! I use mysql as userdb, which contains two type of password schemes: DES and MD5-CRYPT. I read there : http://wiki.dovecot.org/Authentication/PasswordSchemes that both are supported by dovecot. Unfortunately, dovecot keeps saying: Not a valid MD5-CRYPT or PLAIN-MD5 password when looking for a user with DES encrypted password. Is dovecot able to recognize password scheme, or do I have to do something else ? I can't add {DES} to DES passwords, as this database is used with many other softwares. Thanks a lot for your help Pierre

[Dovecot] Two different issues with dovecot 1.1.13
by Stuart Rowan 20 Jan '10

20 Jan '10

Hi Timo, I'm using Debian backports.org dovecot-imapd, 1:1.1.13-2~bpo50+1. I've got two different issues, a reoccurring, seemingly harmless one about "Corrupted index cache file" (boring.txt) and one that went bonkers over the least few days (bt.txt) causing much spamming of the logs. I've made bt.txt stop happening by just rm'ing dovecot.index* : find Maildir/ -type f -name 'dovecot.index*' -print0 | xargs -0r rm ... which I realise may not be the most helpful thing to have done from your point of view. Anyway I just wanted to let you know about both of these. If one or both are already known about or already fixed by a later version of Dovecot, great and sorry for the noise! If not, and you want any more information etc., let me know. Many thanks, Stu. dovecot: 2009-07-28 10:23:16 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 10:23:56 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 08:05:54 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:54 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f0e851941a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:54 Error: child 20007 (imap) killed with signal 6 (core dumps disabled) dovecot: 2009-07-28 08:05:56 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:56 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f2edf08b1a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:56 Error: child 20984 (imap) killed with signal 6 (core dumps disabled)

[Dovecot] Autobuilder packages for Debian stable/i386 now available
by Stephan Bosch 20 Jan '10

20 Jan '10

Hi, A few days back I started the first automated slave builder that produces bleeding edge Debian stable packages for Dovecot v1.2 and v2.0. It uses the source packages already provided by the automated master repository (which builds binary packages for Debian testing), so that the version numbers and content are equal throughout all Debian releases. The repository is available as follows: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-1.2 main Or, for Dovecot v2.0: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.0 main Read this for more information: http://wiki.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages I hope to add amd64 binary support soon. Regards, Stephan.

Re: [Dovecot] Oracle SQL driver

Your commit appears to ignore errors and just commit everything > that goes through? Also since nothing is actually sent before commit(), > your rollback() shouldn't need to send ROLLBACK. You right. I've corrected the transaction handling mechanism. The only thing I couldn't understand: why rollback() shouldn't need to make real ROLLBACK? In case when whole transaction was failed succeded statements will remain uncommited. Then they will be commited later on next successful transaction. May be ROLLBACK is still needed? > The "VARCHAR sqltext[2048]" seems like an unnecessary restriction on the > query length. Wasn't there a way to do this without the limit? Or in AFAIK there is no possibility to use C types in PREPARE statement. Also Oracle cannot handle unsized VARCHARs. I've increased VARCHAR size to 65535. > test_connection() seems unnecessary. Right you are. > Couldn't driver_oracle_generate_name() be simply: > static unsigned int counter = 0; > return i_strdup_printf("ORACONN_%x", ++counter); =) Right. > driver_oracle_escape_string() really should be escaping the string. I made this function to replace single quote in string with two single quotes. IMHO this should be enough. How do you think? > Kind of annoying that each query needs a cursor, even though nearly all > queries are expected to return only a single row, but I guess that can't > be helped with the current API.. Yes. There are no other ways to work with untyped statements in OCI. But Oracle claims that all these statements shouldn't produce significant performance impact. The new version attached.

Have you configured Dovecot deliver as your MDA? See: http://wiki.dovecot.org/LDA N.

Re: [Dovecot] How can I configure dovecot as gmail imap proxy
by Supratik Goswami 20 Jan '10

20 Jan '10

Here the proxy server should authenticate the user. If the user is in the list of authenticated users then dovecot will allow to connect to imap.gmail.com. Consider a scenario where a client tries to read his mailbox from imap.gmail.com:993. Client executes the command "mutt -f imaps://imap.gmail.com", the request is first authenticated at the proxy server. If the request is coming from a valid user, dovecot will allow to connect to imap.gmail.com and fetch mails for that user. Can you please help me with the steps to configure the server. Warm Regards Supratik

[Dovecot] LDA and POP3/IMAP user_query
by Michael 20 Jan '10

20 Jan '10

How do I get IMAP+POP3 vs. LDA to use different user_query statements? The problem is that the input fields are different. IMAP/POP3 is an email address LDA is a username I have written a long statement to try and cater for both however it still only works 99% of the time, and the remaining 1% fails. The 1% that fails sees the mail being delivered to the wrong mbox. In this particular case the same client owned both mboxes so it was ok, but if this had not been the case things could have gotten real embarrassing. Think of the following: abcwidgets(a)theirdomain.tld mailuser1 mailuser1(a)adomain.tld mailuser2 Now when using the Postfix LDA, email for each address is properly delivered to the specified mbox, however in this case because their is a matching name for the mbox and the email address lefthand content, the compound SQL query returns both results and the LDA will use the first one, which in this case was the wrong one. This is the query used: user_query = \ SELECT mailboxes.username AS user, mailboxes.uid, mailboxes.gid, \ concat('*:storage=',mailquota,'M') AS quota_rule \ FROM mailboxes JOIN accounts ON accounts.username = mailboxes.username \ WHERE ((mailboxes.username = '%n' AND accounts.active='1') || \ (mailboxes.email = '%u' AND mailboxes.active='1' AND accounts.active='1') || \ (mailboxes.email = CONCAT('@','%d') AND mailboxes.active='1' \ AND (SELECT COUNT(email) FROM mailboxes WHERE email='%u') = '0')) which additionally caters for the few catch alls our users have. I think this is a massive oversight in the design of Dovecot to use one query to for 2 separate and distinct processes, that both use different parameters. From what I can tell it seems to assume that a mail system will always use username@domain addresses, and never anything more arbitrary. Has anyone found a way around this? Michael

[Dovecot] shared namespaces with common prefix prefix
by Frank Cusack 19 Jan '10

19 Jan '10

Can shared/public namespaces' prefixes have a common prefix? :) namespace public { separator = / prefix = zz/shared/ location = maildir:/var/maildir/shared:INDEX=/var/maildir/%n/shared subscriptions = no } # to share other employees mailboxes (term'd or admin access) namespace shared { separator = / prefix = zz/shared/%%u/ location = maildir:/var/maildir/%%n:INDEX=/var/maildir/users/%%u subscriptions = no list = children } Since I added the shared namespace, I can no longer access the public namespace. The folders show up but then trying to access one gets the error that the mailbox doesn't exist. If they can't have a common part of the prefix, is that an IMAP limitation or could dovecot conceivably handle it? -frank

[Dovecot] Log the virtual email address and not the local account - dovecot 1.2.2 w/ MySQL
by Bill 19 Jan '10

19 Jan '10

I recently started using dovecot and have it working well but I have one item I haven't been able to find an answer for. I am using MySQL with Dovecot for authentication with my virtual email customers. When the user logs in and checks email a log entry is recorded. Instead of the email address (bob(a)bob.net) being logged it records the local account (vemail101) in the POP3 log. How can I get dovecot to reflect the email address that the customer logged in with instead of the local account? Thx, Bill

[Dovecot] fts squat non-english search for 2 words
by vuser1＠test123.ru 19 Jan '10

19 Jan '10

Hello, It looks I encoutered a bug or misconfiguration. fts_squat search for subject and body works excellent for English mails. For non-English (in particular, Russian) it works only when query consists of 1 word. Phrases - 2 and more words - always returns nothing. Example: search for "planet" ("планета") returns results, search for "Earth" ("Земля") also returns results, but "planet Earth" ("планета Земля") returns nothing. But there are emails having exact phrase "planet Earth". This problem occurs only for non-English queries, both for search in subject and in email body. I tried web-mail Horde 3.2 and Thunderbird. I turned fts plugin off and it correctly finds phrases with 2 and more russian words! So problem is squat. Is it a bug or known config issue?

[Dovecot] virtual namespace question
by Josephus 19 Jan '10

19 Jan '10

Hi, I'm wondering if it is possible to create a virtual namespace on a prefix other than "virtual/". My goal is to mix IMAP folders with virtual folders on the same folder level (prefix = ""). mail_location = maildir:/data/mail/%d/%u/ # Virtual namespace private { prefix = separator = / location = virtual:/data/mail/%d/%u/virtual } # Default namespace private { separator = / prefix = inbox = yes } With this configuration the folders show up on the same level, but I'm unable to subscribe to them. When I change the prefix back to "virtual/" it works, but folders are still gruoped under "virtual". Funny thing is, when I use a prefix something like "vfolder/", the root folder is no longer greyed out in my MUA (TB3), and I get a "Mailbox doesn't exist: vfolder" error msg if I click on it. BR, Jos

[Dovecot] Best way of dealing with Case-Sensitive Issues in Dovecot
by Mario Antonio 19 Jan '10

19 Jan '10

In order to deal with case-sensitive issues, I am thinking to use the variable %L (adding it to my current configs --as suggested before by other users in this list) in the configuration files in this way: In Dovecot.conf: mail_location = maildir:/vmail/%Ld/%Ln/Maildir:INDEX=/indexes/%Ld/%Ln auth default: username_format: %Lu passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/vmail/%Ld/%Ln allow_all_users=yes In dovecot-sql.conf: password_query = select concat(virtual_users.user, '@', virtual_domains.name) AS user, virtual_users.password as password \ from virtual_users LEFT JOIN virtual_domains ON virtual_users.domain_id=virtual_domains.id \ where virtual_users.user='%Ln' and virtual_domains.name='%Ld' and virtual_users.status = 1 and virtual_domains.status = 1; user_query = SELECT 5000 AS uid,5000 AS gid,'/vmail/%Ld/%Ln' as home, \ concat('*:storage= ', virtual_users.quota_kb) AS quota_rule \ from virtual_users LEFT JOIN virtual_domains ON virtual_users.domain_id=virtual_domains.id \ where virtual_users.user='%Ln' and virtual_domains.name='%Ld' Is this the correct way of assuring lowercase use all over the place? Can I use the variable %L in where sql statements? Regards, Mario Antonio

[Dovecot] expire plugin doesn't find mail location
by Roland Rosenfeld 19 Jan '10

19 Jan '10

Hi! After searching for hours now, I give up and have to ask here. I try to use the expire plugin but it always tries to expire my mails instead of the mails of the user. I read about the "Mail location setting problem (v1.1-v1.2) and configured a "mail" extra field in the userdb, but that doesn't have the effect I want. I have not idea, what I could try out more, so I ask here. My setup is the following: # 1.2.9: /usr/local/dovecot/etc/dovecot.conf # OS: SunOS 5.10 sun4v zfs syslog_facility: local6 protocols: imap pop3 managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000, *:4190 ssl: no disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable(default): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3-login login_executable(managesieve): /usr/local/dovecot/libexec/dovecot/managesieve-login mail_uid: 2001 mail_gid: 2001 mail_location: maildir:/var/mailstore/%2Mn/%n/mail mail_debug: yes mail_executable(default): /usr/local/dovecot/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3 mail_executable(managesieve): /usr/local/dovecot/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota expire mail_plugins(imap): quota imap_quota expire mail_plugins(pop3): quota expire mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot/lib/dovecot/pop3 mail_plugin_dir(managesieve): /usr/local/dovecot/lib/dovecot/managesieve pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u pop3_uidl_format(managesieve): %08Xu%08Xv namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)netcologne.de hostname: mailstore20.netcologne.de mail_plugins: sieve quota expire auth_socket_path: /usr/local/dovecot/var/run/dovecot/auth-master auth default: master_user_separator: * verbose: yes debug: yes passdb: driver: passwd-file args: /usr/local/dovecot/etc/passwd.master pass: yes master: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /usr/local/dovecot/var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir expire: INBOX 60 Spam 60 Papierkorb 60 Trash 1 expire_dict: proxy::expire dict: expire: mysql:/usr/local/dovecot/etc/dovecot-dict-expire.conf With the following dovecot-sql.conf: driver = mysql connect = host=localhost dbname=cyrus user=cyrus password=XXXX default_pass_scheme = CRYPT password_query = \ SELECT username, password, concat('*:storage=', quota) AS userdb_quota_rule, '/var/mailstore/%2Mn/%n' as userdb_home, 'maildir:/var/mailstore/%2Mn/%n/mail' as userdb_mail \ FROM passwd WHERE username='%n' user_query = \ SELECT concat('*:storage=', quota) AS quota_rule, '/var/mailstore/%2Mn/%n' as home, 'maildir:/var/mailstore/%2Mn/%n/mail' as mail \ FROM passwd WHERE username='%n' And this is dovecot-dict-expire.conf: connect = host=localhost dbname=dovecot user=dovecot password=XXXXXX map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } In user test's Trash folder there are mails that are older than 1 day and in dovecot.expires there is +----------+---------+--------------+ | username | mailbox | expire_stamp | +----------+---------+--------------+ | test | Trash | 1262779049 | +----------+---------+--------------+ But if I run /usr/local/dovecot/sbin/dovecot --exec-mail ext /usr/local/dovecot/libexec/dovecot/expire-tool.sh --test I get the following output: Info: Loading modules from directory: /usr/local/dovecot/lib/dovecot/imap Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib20_expire_plugin.so Info: Quota root: name= backend=maildir args= Info: expire: pattern=INBOX type=expunge secs=5184000 Info: expire: pattern=Spam type=expunge secs=5184000 Info: expire: pattern=Papierkorb type=expunge secs=5184000 Info: expire: pattern=Trash type=expunge secs=86400 Info: auth input: quota_rule=*:storage=10000 Info: auth input: home=/var/mailstore/09/test Info: auth input: mail=maildir:/var/mailstore/09/test/mail Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes Info: maildir: data=/var/mailstore/df/rrosenfeld/mail Info: maildir++: root=/var/mailstore/df/rrosenfeld/mail, index=, control=, inbox=/var/mailstore/df/rrosenfeld/mail Info: test/Trash: no messages left Info: test/Spam: stop, expire time in future: Sat Mar 6 12:35:10 2010 As you can see, it uses my username (rrosenfeld) instead of the username "test", whose mailbox should be expired. But while the above it printed to the console I get the following in the logfile: Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] dict: mysql: Connected to localhost (dovecot) Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): master in: USER 1 test service=internal Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): prefetch(test): passdb didn't return userdb entries, trying the next userdb Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth-worker(default): sql(test): SELECT concat('*:storage=', quota) AS quota_rule, '/var/mailstore/09/test' as home, 'maildir:/var/mailstore/09/test/mail' as mail FROM passwd WHERE username='test' Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth-worker(default): mysql: Connected to localhost (cyrus) Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): master out: USER 1 test quota_rule=*:storage=10000 home=/var/mailstore/09/test mail=maildir:/var/mailstore/09/test/mail As you can see, the auth engine sees the request for the user "test". It also returns the correct home and mail attributes (the above messages were triggered by my expire call!). I tried out to comment out the mail_location from dovecot.conf to make sure that the mail attribute from userdb is used, but this has the effect, that dovecot expire does not know any mail location setting at all and tries some "home" directories and different mail storage formats while my setting mail=maildir:/var/mailstore/09/test/mail from the userdb is completely ignored: Info: Loading modules from directory: /usr/local/dovecot/lib/dovecot/imap Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib20_expire_plugin.so Info: Quota root: name= backend=maildir args= Info: expire: pattern=INBOX type=expunge secs=5184000 Info: expire: pattern=Spam type=expunge secs=5184000 Info: expire: pattern=Papierkorb type=expunge secs=5184000 Info: expire: pattern=Trash type=expunge secs=86400 Info: auth input: quota_rule=*:storage=10000 Info: auth input: home=/var/mailstore/09/test Info: auth input: mail=maildir:/var/mailstore/09/test/mail Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes Info: cydir: mailbox location not given Info: cydir: Couldn't create mail storage : Root mail directory not given Info: dbox: mailbox location not given Info: dbox: Couldn't create mail storage : Root mail directory not given Info: maildir: access(/var/mailstore/09/test/Maildir, rwx): failed: No such file or directory Info: maildir: couldn't find root dir Info: maildir: Couldn't create mail storage : Root mail directory not given Info: mbox: root exists (/var/mailstore/09/test/mail) Info: mbox: INBOX: access(/var/mail/test, rw) failed: No such file or directory Info: mbox: INBOX: access(/var/spool/mail/test, rw) failed: No such file or directory Info: mbox: INBOX defaulted to /var/mailstore/09/test/mail/inbox Info: fs: root=/var/mailstore/09/test/mail, index=, control=, inbox=/var/mailstore/09/test/mail/inbox Info: test/Trash: no messages left Info: test/Spam: stop, expire time in future: Sat Mar 6 12:35:10 2010 As you can see, expire tries to access different (default?) mailbox typies instead of simply using maildir:/var/mailstore/09/test/mail as defined in the userdb. So my main problem seems to be, that the mail attribute from the userdb is completely ignored in expire calls. But how do I fix this?

Hi, sometimes mails that i discard via sieve gets delivered to my inbox and i can not figure out why. So i hope you can give me a hint. My setup is: I use a self compiled dovecot 1.2.4 with installed sieve and managesieve plugin. Incoming mails a processed by Postfix and the delivered to Procmail. Procmail invokes Spamassassin and discard all mails marked as spam. The other mails are passed to Dovecot deliver this way: :0 w | /opt/dovecot/libexec/dovecot/deliver For moving mails to subdirectorys this works always, but not for mails that are discard via Sieve. Examples are: if header :contains "List-Id" "git.vger.kernel.org" { if header :contains "Subject" "[ANNOUNCE]" { fileinto "Announce"; stop; } if header :contains "Subject" "[ANN]" { fileinto "Announce"; stop; } if header :contains "Subject" "[PATCH" { discard; stop; } fileinto "Lists.Git"; stop; } or if header :contains "Organization" "web.de" { discard; stop; } This often works, but sometimes it fails. Procmail reports then that deliver reported an error (but not which) and delivers them to my inbox. There are also no message in dovecots or dovecot delivers log file. Dose anybody have an idea?

Hi, I want to configure dovecot as gmail imap proxy. If any system in my network wants to connect to imap.gmail.com,993 it has to go through the dovecot proxy. Is it possible to setup such environment with dovecot? If yes, can you please help me to configure my dovecot server. Warm Regards Supratik

Hi all, is there some easy way to inform Dovecot about a new delivery, which has happened after postfix invoked maildrop, so the index files would be updated?

[Dovecot] Socket permission 432/384 and dovecot.conf
by Seba 19 Jan '10

19 Jan '10

Sorry for that question but: when you set in dovecot.conf this for example: socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } and you run "dovecot -n" you'll see client: path: /var/spool/postfix/private/auth mode: 432 I'm wondering about the mode "432" - how is this value calculated? Same for the auth/master socket socket - the value ist "384" and in dovecot.conf it's 0600. Thanks for any info. Seba

[Dovecot] Dovecot Proxy and environment variables
by BaQs 19 Jan '10

19 Jan '10

Dear list, First of all, I am French so excuse my bad english. I am currently using dovecot proxy feature, using sql backend. I "proxy" the imap/pop requests to another server, let's say server2. On server2, I use a script to keep up to date a "pop before smtp auth" database. I used mail_executable = /path/to/this/script.sh ... My problem is: the $IP environment variable on server2 is the proxy's IP. How could I give a variable from proxy to server2, or simply get the real client public IP ? Thanks a lot in advance for your answers Pierre. PS: let me also thank very much dovecot developers and community !

[Dovecot] No filelocking at "shared-mailboxes" dictionary?
by Peer Heinlein 19 Jan '10

19 Jan '10

Using imapsync I changed many ACLs on many accounts simultaneously in four concurrent IMAP-sessions. I started with an empty file "shared-mailboxes". But after the sync the file "shared-mailboxes" has been crashed. I found broken lines and I'm missing some entrys. Is it possible that there's no filelocking on that file? I used the ext3 filesystem. That's what shred-mailboxes looks like at the moment: shared/shared-box 1 shared/shared-boxes/user/user1.example.com/user2.example.com 1 .example.com/user5.example.com 1 hared/shared-boxes/user/user6.example.com/user4.example.c2442203233424^? 1 ser/user7.example.com/user2.example.com Peer dovecot -n: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.39-0.2-default x86_64 openSUSE 11.1 (x86_64) protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/old.pem ssl_key_file: /etc/ssl/old.pem shutdown_clients: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_max_processes_count: 512 max_mail_processes: 1024 mail_max_userip_connections(default): 40 mail_max_userip_connections(imap): 40 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes mail_uid: vmail mail_gid: vmail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap-usernamenmigration mail_executable(imap): /usr/lib/dovecot/imap-usernamenmigration mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: zz_SHARED_ACCOUNTS/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: yes lda: postmaster_address: postmaster(a)iea-dpc.org mail_plugins: quota acl sieve mail_plugin_dir: /usr/lib64/dovecot/modules/lda quota_full_tempfail: yes auth default: mechanisms: plain login digest-md5 cram-md5 verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: static args: uid=5001 gid=5001 socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: quota: maildir quota_rule: *:storage=102400 acl: vfile acl_shared_dict: file:/var/lib/dovecot/shared-mailboxes sieve: ~/.dovecot.sieve sieve_dir: ~/sieve -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030 / 40 50 51 - 0 Fax: 030 / 40 50 51 - 19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Upgrade path questions
by Thomas M Goerger 18 Jan '10

18 Jan '10

Hi, We are currently running Dovecot v1.1.6 on our servers, and are contemplating an upgrade to 1.2, or 2.0 soon. We are wondering how many organizations are still running a 1.1 version of Dovecot, and if anyone has any thoughts on this transition. Have you upgraded from 1.1 to 1.2? What are your experiences with this? Have you upgraded from 1.1 to 2.0 directly? What are your experiences this way? We are also running an environment with both mbox and maildir formats. How many of you are running similarly, or are running solely maildir or mbox? We're just looking to gather information going forward, and anything you might be able to contribute would be very helpful. Thanks! ************************************************************************* * Tom Goerger - Email/Unix System Administrator * * * * University of Minnesota Email: tmg(a)umn.edu * * Operations, Infrastructure and Architecture Phone: 4-5804 * * Internet Services Office: 626J WBOB * * * *************************************************************************

[Dovecot] Strange permission problem with Maildir

[Dovecot] how-to use dsync to do a 2 ways replication ?
by Eric Belhomme 18 Jan '10

18 Jan '10

Hi, I want to set-up two dovecot imap servers, with active-active replicated maildirs. The goal is to have a hosted public server on Internet, and a private server on my LAN to speed-up local connections. So I compiled dovecot 2.0 beta 1 in order to use dsync utility... Actually my config is pretty simple as I just want to setup a proof of concept before going ahead in this way : (Both servers are Debian Lenny with excatly the same config) mail0:~# /usr/local/dovecot2/sbin/dovecot -n # 2.0.beta1: /etc/dovecot2/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.3 auth_debug = yes auth_verbose = yes login_trusted_networks = 172.16.64.0/18 mail_location = maildir:%h passdb { args = /etc/dovecot/userpasswd deny = no driver = passwd-file } postmaster_address = postmaster(a)example.com service pop3-login { inet_listener { port = 110 } inet_listener { port = 995 ssl = yes } } service imap-login { inet_listener { port = 143 } inet_listener { port = 993 ssl = yes } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/userpasswd driver = passwd-file } I logged on the first server with an IMAP client then I copied many email through IMAP, then I launched dsync as root : /usr/local/dovecot2/bin/dsync -v mirror 'ssh eole.it.fr.eve /usr/local/dovecot2/bin/dsync' root(a)eole.it.fr.eve's password: dsync-local(root): Error: Can't create mailbox ssh: Mailbox already exists dsync-local(root): Error: Can't create mailbox aptitude: Mailbox already exists dsync-local(root): Error: Can't create mailbox debtags: Mailbox already exists dsync-local(root): Info: debtags: only in source dsync-local(root): Info: aptitude: only in source dsync-local(root): Info: ssh: only in source dsync-local(root): Info: ssh: only in dest dsync-local(root): Info: aptitude: only in dest dsync-local(root): Info: debtags: only in dest dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: msg iteration failed: Couldn't open mailbox dsync-remote(root): Error: Can't create mailbox debtags: Mailbox already exists dsync-remote(root): Error: Can't create mailbox aptitude: Mailbox already exists dsync-remote(root): Error: Can't create mailbox ssh: Mailbox already exists dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: msg iteration failed: Couldn't open mailbox dsync-remote(root): Error: command MSG-LIST failed dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox aptitude changed its GUID (cffc9a2d85154e4b47180000b31a5865 -> 521e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox debtags changed its GUID (d1fc9a2d85154e4b47180000b31a5865 -> 501e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox aptitude changed its GUID (cffc9a2d85154e4b47180000b31a5865 -> 521e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox debtags changed its GUID (d1fc9a2d85154e4b47180000b31a5865 -> 501e9f2850234e4b3a2b0000d0cf7273) mail0:~# dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox aptitude changed its GUID (521e9f2850234e4b3a2b0000d0cf7273 -> cffc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox ssh changed its GUID (541e9f2850234e4b3a2b0000d0cf7273 -> cdfc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox aptitude changed its GUID (521e9f2850234e4b3a2b0000d0cf7273 -> cffc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox ssh changed its GUID (541e9f2850234e4b3a2b0000d0cf7273 -> cdfc9a2d85154e4b47180000b31a5865) It seems dsync tries to use my system user database instead of the /etc/dovecot/userpasswd file !

[Dovecot] Adding support for a new storage format - plugin?
by Brad Hards 18 Jan '10

18 Jan '10

Hi, I've spent a little bit of time looking at the dovecot source (from the unstable 2.0 development tree), and I think I'm starting to get it together... Background: I'm interested in dovecot to provide IMAP access to an existing database backed server store (http://www.openchange.org for more details). The goal is to provide parallel access using either IMAP or the exchange RPC protocol. If I understand this stuff: * I can potentially provide access to the store using a plugin. It looks like the virtual mailbox plugin is a potential example here. * I may need to also provide an authentication plugin (not sure whether I can just re-use the existing ldap backend - quite possibly a useful option in my scenario) * I probably can't use the existing SQL code, since it uses its own schema. * I may need to provide some locking to ensure things are always in a consistent state for both IMAP and exchange RPC. Comments? Suggestions? Brad

I need to listen on both 993 (for some stupid clients I have to support that can't do START TLS) and 80 (to get past L3/L4 firewalls). I'd like to do it in dovecot rather than use nc, ipfilter or whatever. -frank

[Dovecot] handling filename of compressed messages
by Leonardo Rodrigues 17 Jan '10

17 Jan '10

i'm running dovecot 1.2.9 and, among other things, i have the zlib plugin enabled. A shell script runs once a day to compresses all not still compressed files on the users maildirs. so far so good, it works fine, there's no problem on that. what i think is not happening 100% correctly is the following: 1) user receives a message 2) BEFORE the compress routine runs, filename is: new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207 3) AFTER the compress routine, filename is now: new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz 4) user check his mail .... and now the filename is cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S 5) user replies that mail .... and now the filename is cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS i'm aware that dovecot doesnt need the '.gz' extension on the file to recognize that as a gzipped file. Even without the .gz extension, dovecot is correctly reading the file. the '.gz' is not even necessary on the filename and still dovecot can handle it fine. anyway, i would like to suggest dovecot to handle the filename to keep the .gz extension, if that exists. This could help sysadmins to easily identify gzipped files on the maildirs and make anything with them, if that's desired. i would like to see dovecot changing filenames properly and keeping the .gz extension always, for example cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,S.gz instead of cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,RS.gz instead of cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] shared namespace bug?
by Patrick Kaiser 14 Jan '10

14 Jan '10

Hi, finally i got shared namespace up and running. But for example if user peter.griffin shares his inbox to another user, the LIST "" "*" output on telnet looks like: a02 LIST "" "*" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect) "/" "shared/peter.griffi" * LIST (\HasChildren) "/" "shared/peter.griffin" * LIST (\HasNoChildren) "/" "shared/peter.griffinINBOX" a02 OK List completed. To share the inbox I previously run as logged in user peter.griffin a02 SETACL inbox peter.griffin lwxrk If I look in thunderbird, i can see under "share" two folders: peter.griffi and peter.griffin. Have i made something wrong, or is this a bug? Hope someone can help me. thanks, patrick -- Name : Patrick Kaiser Email : patrick.kaiser(a)argonius.de Phone : +49 (178) 8452388 Website : http://www.argonius.de GPG Key : http://www.argonius.de/key.pub

[Dovecot] uw-imap compatability hack?
by Simon Annetts 14 Jan '10

14 Jan '10

Hi all Apologies if this question has already been asked before... I'm migrating from a uw-imap setup where the mail folders were in a subdir mail/ in the users' home directories. All of the clients are configured with 'IMAP server directory' set to mail/ (Thunderbird) and it would be difficult to change this on the clients (there are 1000s of them) I want to use maildir and I have converted the original mbox files in ~mail/ to maildir format. So in ~Maildir/ I now have: cur dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist .Drafts new .Sent-Items .Spam subscriptions tmp .Trash if I remove the mail/ setting from 'IMAP server directory' in the client, then everything works as expected and all the folders are visible. With this setting in however, only the inbox is visible and attempts to click on another folder, say Trash result in the client error: Mailbox doesn't exist .mail.Trash I've tried various namespace configurations I found in the namespaces wiki example but none seem to work. What I would really like to happen is for dovecot to ignore this setting supplied by the client and not to prepend .mail onto the folders it is looking for. Is there a clever namespace that will do this for me, or some other setting or symlink trickery? Ultimately I want to support clients that might have both mail/ and nothing set in this box.

[Dovecot] How to configure dovecot to listen on multiple separate port numbers
by Rick Thomas 14 Jan '10

14 Jan '10

Is there any way to tell dovecot to listen for imap/imaps requests on all interfaces on multiple separate ports? For example, can I do this: protocol imap { listen = *:10143 listen = *:143 ssl_listen = *:10993 ssl_listen = *:993 ... } Thanks! Rick

[Dovecot] Sieve and ManageSieve for Dovecot v2.0 merged into one repository
by Stephan Bosch 13 Jan '10

13 Jan '10

Hi, I've merged the Mercurial repositories for Sieve and ManageSieve for Dovecot v2.0 into one repository: http://hg.rename-it.nl/dovecot-2.0-pigeonhole This simplifies the build process significantly. It also allows tightly integrating the implementation of the script storage with the main Sieve library, enabling the possibility to implement alternate means of script storage, like for instance a SQL or LDAP database. Building ManageSieve is still optional as outlined in the INSTALL file. The old v2.0 repositories will be archived soon. I'm slowly but surely progressing towards a first Pigeonhole release for Dovecot v2.0. Regards, Stephan

[Dovecot] Allow POP3 per Domain
by Hauke Hagedorn 13 Jan '10

13 Jan '10

Hi List, I wonder, if it is possible to "switch" POP3 on or off for specific domains. Actually I want to disallow POP3-logins for a certain domain, whereas users can still login into a webinterface via IMAP. Curently I use Dovecot 1.1.11 on current Ubuntu 9.10 with a mySQL backend for authentication. With kind regards Hauke

[Dovecot] Discard duplicate messages at delivery?
by Nicolas KOWALSKI 12 Jan '10

12 Jan '10

Hello, I am using dovecot 1.2.9, and the sieve plugin for filtering incoming messages into specific folders. The MTA is postfix, and deliver is called using the "mailbox_command = /usr/lib/dovecot/deliver" directive. Is it possible to make dovecot's deliver discard duplicate messages? With cyrus there is a duplicatesuppression directive which works well (http://cyrusimap.web.cmu.edu/imapd/overview.html#duplicate) With procmail, this can be done with the following recipe, but I did not found an equivalent for dovecot: # One often receives duplicate messages for cross-postings to mailing # lists, or explicit replies to a post from you in addition to the # mailing list message. # # The following recipe eliminates all duplicate messages. It tells # formail(1) to keep a cache file of the Message-IDs of the most # recent messages you've received. Since Message-IDs are guaranteed # unique for distinct messages, they are ideally suited to weed out # duplicates. # :0 Wh: msgid.lock | formail -D 65536 .saves.msgid Thanks, -- Nicolas

[Dovecot] Silent migration from mbox to maildir?
by Götz Reinicke - IT-Koordinator 12 Jan '10

12 Jan '10

Hi, after migrating to a new hardware (which is soo soooo mutch faster than the old one) I start to think about migrating from mbox to maildir. I'v read some docs and wikies and some questions are unanswered or maybe I skip the answers: - Is it possible to migrate the mboxes "silent" e.g. if a user logs in the mbox is converted? - regarding the Namespaces wiki article, it is possible to mix mbox and Maildir for one user. Is it possible to use this setup for all newly created accounts? or - Is it possible to have maildir set up for all newly created accounts while the old accounts still use mbox? Thanks for any suggestion and best regards, Götz -- Götz Reinicke IT-Koordinator Tel. +49 7141 969 420 Fax +49 7141 969 55 420 E-Mail goetz.reinicke(a)filmakademie.de Filmakademie Baden-Württemberg GmbH Akademiehof 10 71638 Ludwigsburg www.filmakademie.de Eintragung Amtsgericht Stuttgart HRB 205016 Vorsitzende des Aufsichtsrats: Prof. Dr. Claudia Hübner Staatsrätin für Demographischen Wandel und für Senioren im Staatsministerium Geschäftsführer: Prof. Thomas Schadt

[Dovecot] Dovecot Quota Problem
by Ken Price 12 Jan '10

12 Jan '10

I'm using Dovecot LDA with Exim. I'm also using Dictionary Quotas in a MySQL database. I want to avoid backscatter completely, so I set "quota_full_tempfail = yes" and handle quota checking in the Exim RCPT ACL during the SMTP session. The problem lies in the case where a user's account is nearly full. Smaller messages will continue to come through, but a larger message would get queued for retry since it will push the account over quota. I need Dovecot's quota to exhibit the same behavior as Exim's "quota_is_inclusive=false". >From Exim docs: quota_is_inclusive=false When this is done, the check for exceeding the quota does not include the current message. Thus, deliveries continue until the quota has been exceeded; thereafter, no futher messages are delivered. Any ideas on how I can implement this inside of Dovecot? Thanks, -Ken Price

[Dovecot] Problem in LSUB?
by Sergio Villar Senin 12 Jan '10

12 Jan '10

Hi guys, I'm not 100% sure about the dovecot version in the server because I don't have access to it, just an account, but I think it's 1.1-rc4 I'm an email client developer and I have a doubt about the behaviour of LSUB that I think it's buggy. See this chat with the server 40 LIST "" INBOX * LIST (\HasChildren) "." "INBOX" 40 OK List completed. 41 LIST "" INBOX* * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.Trash" * LIST (\HasChildren) "." "INBOX.folder1" * LIST (\HasNoChildren) "." "INBOX.folder1.folder12" * LIST (\HasNoChildren) "." "INBOX.folder2" * LIST (\HasNoChildren) "." "INBOX.Sent" * LIST (\HasNoChildren) "." "INBOX.Drafts" * LIST (\HasNoChildren) "." "INBOX.Spam" * LIST (\HasNoChildren) "."

My question is, why "LSUB "" INBOX" does not return anything while "LSUB "" INBOX*" does ? Br

[Dovecot] Dovecot (IMAP) Hangs sometimes
by Mario Gomide 12 Jan '10

12 Jan '10

Hi there! I'm using Dovecot 1.0.7 in RHEL 5.4 64bits as a IMAP/POP3 server. Dovecot authenticates users against an AD server via kerberos (pam configuration) and clients connect to it via IMAPs and POP3s with SSL. Webmail is in localhost and connects locally also with SSL. All is fine and people use the email server normally and with no problems. But, I have noticed that dovecot hangs sometimes. Usually twice a day somewhere between 09:40 and 10:00 a.m and in the afternoon at about 3:00 p.m. The problem starts when webmail takes long to authenticate and show folders and stuff. After a while it times out and doesn't connect. Then the clients (e.g. outlook, thunderbird) start taking long to connect and then they timeout. Important: Only IMAP connections timeout! POP3 continues ok. This latency keeps on going until dovecot finally hangs (after about 10 to 15 minutes). The problem is solved when I restart/reload dovecot. I'm not sure as to what's going on! I check the log, but it has been hard to pinpoint an exact event or to detect when the problem begins. Any ideas? BTW: what's the real difference between reload and restart? Thanks a lot! Mario

Thanks Stephan, I have the extdata plugin compiled, and am now trying to make a global sieve script to test it. I'm running into problems when using sievec to compile the script - I'm not getting the plugin's variables that are provided in dovecot.conf's plugin {}. I added a few sieve_sys_warning messages to track the calls to sieve_setting_get() <output> /usr/local/bin/sievec -d -P sieve_extdata /usr/local/etc/dovecot/sieve/before.sv Warning: sieve: sieve_setting_get: req: 'sieve_max_script_size' res: '(null)' Warning: sieve: sieve_setting_get: req: 'sieve_max_actions' res: '(null)' Warning: sieve: sieve_setting_get: req: 'sieve_max_redirects' res: '(null)' Warning: sieve: sieve_setting_get: req: 'sieve_subaddress_sep' res: '(null)' Warning: sieve: sieve_setting_get: req: 'recipient_delimiter' res: '(null)' Warning: sieve: sieve_setting_get: req: 'sieve_plugin_dir' res: '(null)' Warning: sieve: sieve_setting_get: req: 'sieve_plugins' res: '(null)' Warning: sieve: sieve_setting_get: req: 'sieve_extdata_dict_uri' res: '(null)' Warning: sieve: extdata: no dict uri specified, extension is unconfigured (sieve_extdata_dict_uri is not set). * Required extensions: 0: vacation (9) 1: variables (17) 2: vnd.dovecot.extdata (29) * Main program (block: 1): 00000000: EXTENSIONS [3]: 00000001: vacation 00000002: variables 00000003: SCOPE [0] (end: 00000008) 00000008: vnd.dovecot.extdata 00000009: VACATION 0000000a: (source line: 3) 0000000d: subject: VAR ${extdata.vacation_subject} 00000023: reason: VAR ${extdata.vacation_message} 00000038: handle: STR[77] "${extdata.vacation_message}${extdata.vacation_subject}<default-from><NO-MIME>" 00000088: [End of code] </output> I'm new to dovecot's internals, it looks like it just needs some environment variables provided, but I'm puzzled as to how this is to be done. I've traced it through sievec.c -> sieve_tool_sieve_env -> sieve_tool_get_setting -> getenv() call. More info: 1. I've traced the process, there's no attempt to open or stat any dovecot.conf 2. using tip dovecot-1.2, dovecot-1.2-sieve, pigeonhole-sieve-extdata. I pulled+updated & rebuilt and confirmed the above behaviour just prior to sending this message. 3. The test scripts run because the test framework uses the test_config mechanism to provide sieve_extdata_dict_uri. Any hints on how to get the dovecot.conf data to sievec? Thanks, -Martin Foster

[Dovecot] Same filenames on different servers?
by Alexander Chekalin 11 Jan '10

11 Jan '10

Hi, I'm really fuzzy about some problem on how Dovecot used to name files to store messages in Maildir. I have two identical servers (let's call them "First" and "Second"), and have Dovecot and Exim set up on both of them (Maildirs are used to store messages and boxes). First server is the server to be used by people around, and the Second server is backup one, the only thing it can do while the First is alive is to get (via rsync) First's mail spool. I set up rsync to run every 5 minutes, and that's quite well sync spools from First to Second. So if something wrong happens to First server we simple disconnect it from the network and put Second server in place of First. The problem is that files in Maildirs on First server are named like that: 1262610335.H798006P5447.first.domain.my,S=1962:2, 1262610402.H529761P5596.first.domain.my,S=2975:2, 1262610410.H787724P5657.first.domain.my,S=75691:2, ... and the files on Second server should be named like 1262610335.H798006P5447.second.domain.my,S=1962:2, 1262610402.H529761P5596.second.domain.my,S=2975:2, 1262610410.H787724P5657.second.domain.my,S=75691:2, ... As soon as I enter the Second's mailbox with IMAP client Dovecot used to rename files the way they should be. If after that I rsync spools I'll end up with double sized spool as there'll be both First and Second files: 1262610335.H798006P5447.first.domain.my,S=1962:2, 1262610335.H798006P5447.second.domain.my,S=1962:2, 1262610402.H529761P5596.first.domain.my,S=2975:2, 1262610402.H529761P5596.second.domain.my,S=2975:2, ... Long description for simple problem, yes :) I also tried to set: maildir_copy_preserve_filename = yes but still no luck. My setup is FreeBSD 7.2 with all versions in 1.1.x and 1.2.x branches (now it is 1.2.8). Thank you in advance for you advice, yours, Alexander

[Dovecot] sieve 0.1.14: vacation encodes Subject twice
by Roland Rosenfeld 11 Jan '10

11 Jan '10

Hi! I noticed the following problem in dovecot-1.2-sieve-0.1.14: The following vacation causes trouble with the Subject line: if not exists ["List-Id", "List-Post"] { vacation :days 7 :addresses ["test(a)netcologne.de"] :subject "=?utf-8?b?w4TDlsOc?= sadasd" "Bin gerade nicht hier."; } As you can see, the Subject is already MIME encoded according to RFC2047. Starting with sieve 0.1.14 the subject is now encoded by sieve again, so I get the following in my vacation mail: Subject: =?utf-8?q?=3D=3Futf-8=3Fb=3Fw4TDlsOc=3F=3D?= sadasd As you can see, the RFC2047 encoding is RFC2047 encoded, which results in an unreadable subject. According to RFC5230 section 4.3 this shouldn't happen: The ":subject" parameter specifies a subject line to attach to any vacation response that is generated. UTF-8 characters can be used in the string argument; implementations MUST convert the string to [RFC2047] encoded words if and only if non-ASCII characters are present. Implementations MUST generate an appropriate default subject line as specified below if no :subject parameter is specified. If I understand this right, sieve should do the RFC2047 encoding only if the string is non-ASCII. But the RFC2047 encoded string is already ASCII, so it should not be encoded a second time. I just compared this with sieve 0.1.13, which behaves different: It does not encode the Subject header at all. As long as the managesieve client (in our situation Horde/IMP) encodes the subject, everything works correct, while we run into trouble with 0.1.14. I think that there needs to some mechanism in sieve that checks whether the subject contains non-ASCII and does the encoding only in this case. I just checked out, that 0.1.14 does not encode a non RFC2047 encoded 7bit subject, while a 7bit subject starting with =?utf-8?... is encoded twice.

[Dovecot] How to create UTF encoded folders?
by Kārlis Repsons 11 Jan '10

11 Jan '10

Hey, as I understand from post [1], system folders with UTF-8 chars in their names will only be available for use with Dovecot2 and I certainly look forward to that, but somehow I was short of info about the current use of UTF characters like ā, Ž etc. Should I just omit thinking about modified-UTF-7, avoid those characters for the time being and then with Dovecot2 create UTF-8 encoded folders with MUA and also on fs? Or there is something to know anyway? Please suggest as it would be a pity not to create folders with utf symbols... [1] http://www.mail-archive.com/dovecot@dovecot.org/msg23576.html

[Dovecot] "leave mail on server" workaround
by Kirill Miazine 11 Jan '10

11 Jan '10

Hello, POP users often keep fetched mail on server, by checking for "leave mail on server" or similar option in their client. What would be the best way to disallow them using such approach. That is, what is the best way to force deletion of messages that have been RETRieved in a POP session at the end of that POP session? RETRieved messages will be marked as \Seen, but since users might also use an IMAP client (e.g. webmail), it'll be dangerous to simply delete all \Seen messages in user's mailbox. I'm all open for suggestions. -- -- Kirill Miazine <km(a)krot.org>

[Dovecot] How to tell dovecot to use a specific MTA
by Spyros Tsiolis 10 Jan '10

10 Jan '10

Hello again people, OK. I checked a lot of HOWTOs and documents. One specific document describes how one can make dovecot "talk" to postfix. The procedure is pretty straightforward (taken from the document) : -- . Configuring Postfix and Dovecot Turn off sendmail: service sendmail stop chkconfig sendmail off system-switch-mail (select postfix) -- This is for CentOS systems. My question is pretty simple. How exactly does someone tell dovecot (or the CentOS system) that the MTA used is not a pre-packaged postfix MTA but (in my case as you have pretty much discovered by now) XMail compiled from source (no pre-packaged version AFAIK for CentOS; but even if existed, I would still build it on my own) ? Any help would be appreciated, Regards, spyros

[Dovecot] IMAP client dependence on dovecot mail storage fromat?
by Kārlis Repsons 09 Jan '10

09 Jan '10

Hi, After setting up a maildir tree with :LAYOUT=fs and accessing it with KMail and Thunderbird, various mail client-specific problems appeared, but, as I didn't try with maildir++, I would like to confirm here: does that matter for an IMAP client much if I store mail on server as ":LAYOUT=fs" or maildir++? Can it see differences? I would like to think, that IMAP protocol should provide for all transactions in a standard way and its dovecot's/server's sole business how it stores mail locally. However... These results seem not very good: KMail: try creating a folder "sub" in "parrent" and you'll get "parrent.sub" along with "parrent" on server side. There, however, are no problems with Latvian unicode chars. Thunderbird: it can create a new folder in "parrent" as desired, but it can't display Latvian unicode chars (being such at server side) on client, while, if I try creating a new folder with Thunderbird with these chars, on server it will look somewhat like base64! So I'm really confused. All together these things are pretty frustrating, sure, but I'd like to understand whats the real problem here!

[Dovecot] Sieve > Pigeonhole > external storage with LDAP or other data source available to dovecot
by Martin F. Foster 09 Jan '10

09 Jan '10

I am looking at porting and generalizing an old in-house patch that I'm using for the CMU Sieve plugin. It allows sieve script to test & lookup arguments from LDAP. Before getting too involved in this, I'd like to discuss my goals here in the hopes that someone else also thinks this would be useful. Many heads may make better design? Goal: ------ Allows scripts which are still stored on the filesystem to lookup parameters stored in an LDAP directory. Useful if you provide a global sieve script to implement functions such as "vacation", forwarding to small groups (not a MLM), wish to toggle whether a message is kept in the mailbox after being forwarded, etc. <example> # determine if we always auto-respond, or if we respond with a more vacation-ish setting of every 30d # # sample LDAP entry: # uid: testuser(a)domain.com # mailResponderMode: vacation # mailResponderText: "I'm on vacation, far far from the Internet" (base64 encoded string...) # "always" reply mode, sanitized to once a day if ldap "mailResponderMode" "reply" { vacation :days 1 "ldap@mailResponderText"; } # traditional "vacation" mode, say reply once every 30d if ldap "mailResponderMode" "vacation" { vacation :days 30 "ldap@mailResponderText"; } </example> This introduces: 1. a new command "ldap", to lookup attributes and their values in an LDAP directory using the user's context 2. an extention to the vacation command that looks up the vacation reply text that is triggered by supplying "ldap@ldapAttribute" as the text. 3. other actions not shown above which extends redirect and a few other commands to lookup data from LDAP Related work: 1. Pigeonhole low priority TODO would like to implement alternate script storage, eg: LDAP & SQL. I'm not immediately interested in alternate types of script storage, but for what I want to acheive, I need to sanely access at least an LDAP directory. 2. draft-ietf-sieve-external-lists (http://tools.ietf.org/html/draft-ietf-sieve-external-lists-01) proposes a mechanism to pull mailing list addresses from external storage mechanisms such as LDAP, ACAP or relational databases. I'm interested in this, but would like to extend this functionality beyond just lists as the example above demonstrates. 3. there are security and resource consumption issues with doing this, suggesting that limits should be set, or the use may have to be restricted to global scripts eg: sieve_before or sieve_after The question: - do others on this list see value in the functionality described above? If there's some consensus that this would be useful, I'll flesh out howI think a generalized version of this old patch may behave, then (!) work on an implementation as a plugin to dovecot's sieve. cheers, -Martin Foster martin_foster(a)pacific.net.au martin.foster(a)pacnet.com
