[Dovecot] Howto create maildir in lower case while user login via imap/pop3?
by Zhang Huangbin 26 Mar '08

26 Mar '08

Hi, all. I searched mail archives, but no result. I use OutLook Express on Windows XP as MUA, login username is in upper case, such as 'AAA(a)BBB.COM', when login via imap, dovecot create directories: /home/vmail/ |- BBB.COM/ # <- Domain name |- AAA/ # <- User name |- cur/ |- xxx Here, domain name and user name are in upper case. How can i make it create directories in lower case? # # dovecot -n # # /etc/dovecot.conf log_path: /var/log/dovecot login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: maildir:/%h/%d/%n/:INDEX=/%h/%d/%n/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: mechanisms: plain login user: vmail passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf 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 # # File: /etc/dovecot-ldap.conf # hosts = 127.0.0.1:389 ldap_version = 3 auth_bind = yes dn = cn=vmail,dc=openbsdonly,dc=org dnpass = passwd base = o=%d,o=domains,dc=openbsdonly,dc=org scope = subtree deref = never user_filter = (&(mail=%u)(objectClass=qmailUser)(accountStatus=active)) user_attrs = homeDirectory=home,mailMessageStore=maildir:mail,mailQuota=quota=maildir:storage pass_filter = (mail=%u) pass_attrs = userPassword=password user_global_uid = 2000 user_global_gid = 2000 default_pass_scheme = CRYPT -- Best Regards.

[Dovecot] Changing the order of plugin execution.
by "Fábio M. Catunda" 25 Mar '08

25 Mar '08

Hi! I'm using an acl to avoid deletion of .Trash messages, but I also have mail_log plugin enabled, but I found out some logs of deletion on info.log: deleted: uid=218, msgid=<200802150943.25163.alessio(a)skye.it>, box=Trash The message is still there, but maillog logged that it have been deleted. I believe that this issue is related to the order that plugins are executes, is there a way to change it? dovecot version 1.0.13-1 debian package. Thanks!

[Dovecot] Pegasus Mail 4.41 OK With Dovecot
by Sabahattin Gucukoglu 25 Mar '08

25 Mar '08

Pegasus Mail 4.41 is an excellent client on Windows. It works fine with both Dovecot IMAP and POP3 (APOP, IMAP LOGIN commands only - no SASL). Responds to async events. Supports IMAP STARTTLS. Does not use IDLE - periodic CHECKs. Fast and sensible header caches, light on resources. Offline mode, but read-only, using cache (prefetch options available if body caching enabled, it's not by default to save disk space). Searching is still a bit slow, although it does its best to use IMAP substring searches when it's possible even though the folder metadata is apparently managed locally. Excellent configurability; includes semantics for the different types of separator, prefixes, and a choice of whether or not to support folders w/ messages or w/o in folders. Moves mails for trash; only purges from the Trash folder (expunge after every delete operation and don't provide end-user experience different than local folder management). Provides several tricks for faster IMAP access, one of which is to assume only the client is using the mailbox (they can all be turned off). Closed source. But a very nice client, all round. http://www.pmail.com/ http://community.pmail.com/ Cheers, Sabahattin -- Sabahattin Gucukoglu <mail<at>sabahattin<dash>gucukoglu<dot>com> Address harvesters, snag this: feedme(a)yamta.org Phone: +44 20 88008915 Mobile: +44 7986 053399 http://sabahattin-gucukoglu.com/

[Dovecot] Dovecot and kmail IMAP resources
by Anne Wilson 25 Mar '08

25 Mar '08

For some time now I have been trying to get IMAP resources working on KMail. I have followed the docs from kde, but they tell how to configure cyrus IMAP, so I've had to learn as I went along. After a lot of help from the postfix list I now have a working sasl. The ability of the user 'groupware' to log in with PLAIN has been checked in a telnet session. Everything in KMail has been set up as in the documentation, but it doesn't work. Now I'm wondering if anything in my dovecot configuration needs changing. dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/mail/mail info_log_path: /var/log/mail/mail.info protocols: imap listen: *:143 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: maildir:~/Maildir/ maildir_copy_with_hardlinks: yes auth default: mechanisms: plain login debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: I'd be thankful for any help.

Now all works perfectly :-) Probably at http://wiki.dovecot.org/Plugins/xexec it is good to have link on patch/new version of module, created by you. Or attach to page file. I can do it, if it's ok.

You'll have to point your client to an SMTP server which is willing to accept the mails and forward them. Either you have one running on your server box, or you point directly to your ISP's SMTP server.

[Dovecot] Quotas from Active Directory LDAP

The attached patch provides a compile fix to make it compile without warnings for dovecot-1.1. I only tested whether the module is successfully loaded by Dovecot and not whether XEXEC still does what it is supposed to. It does not segfault on the xexec command, but that is all I tested. I got a backend command error and now it is bed time for me, but there is a good chance that this works if you bother to read the wiki page properly ;) So, consider this to be more like an 'It compiles! Ship it!' kind of fix. But, anyways, it should help you to get where you want. Just apply inside the xexec directory using the usual patch -p1. Let me know what you find out. Regards, Stephan.

Then it will be removed: convert_mail = mbox:/export/mbox/migrate/%u:INBOX=/export/mbox/migrate/%u/%u:INDEX=Maildir:%h/mail/ Should also mention, one server in the cluster was incorrectly running version dovecot-1.0.2 (boy was that fun to track down).

[Dovecot] Using IMAP keywords instead of mailboxes for spam with dovecot-antispam
by Jan Oravec 20 Mar '08

20 Mar '08

Hi, Some email clients, like Evolution, use IMAP keywords to flag spam instead of moving mail to dedicated spam mailbox. This is very useful, as false positives can be easily "moved" to original mailbox simply by removing $Junk keyword. I couldn't find a way how to integrate antispam software, like dspam, with dovecot, so that antispam automatically learns ham/spam. I have found Johannes's dovecot-antispam plugin. Unfortunatelly, it doesn't have IMAP keywords support, autolearn is based on folders. Is there any solution for this use case? Thanks, Jan

[Dovecot] IMAP - multi-simultaneous-user mail store
by Tim Alberts 19 Mar '08

19 Mar '08

I'm finishing converting from POP to IMAP and I'm seeing some potentially powerful uses, but I wonder if my ideas aren't more abuses. I want to create 'multi-user' accounts that allow groups of users to archive and share emails with each other. For example, in the case of a sales department, emails from customers may have requests for new product features. I could create an IMAP storage for sales that allows the sales staff to copy these requests into a common email account. These could then be sorted and searched by the product development team to better determine what customers want where product development should go. Another example, a service/support group has some problem customers that frequently call multiple technicians for support. The service group can save all correspondence with this customer in a single location so they can better work together to provide support for this customer. The possibilities for sharing emails in groups seem endless to me, but it depends on if it's a 'use' or 'abuse' of the IMAP protocol, and if Dovecot in-particular is designed to be able to handle this. Thoughts?

[Dovecot] Converting from UW-IMAP to dovecot - odd client problems
by Michael Durket 19 Mar '08

19 Mar '08

Our installation currently uses an old version of UW-IMAP. Instead of upgrading to the latest version, we're in the process of testing dovecot 1.0.13 on a Solaris 9 machine (using a different set of network ports of course so both the old and new systems can coexist during testing). We've been asking selected users to switch from UW-IMAP to dovecot in order to test various clients and OSes with dovecot. On our system the inboxes are always on local disk, but the indexes and any folders may be on NFS or local disk (it has to do with how and where we added disk as our user population increased over time). Only a single server is ever used and I've made sure for our version of dovecot that the settings specified for NFS are as described in the Wiki article. We've noticed some oddities which we can't figure out: 1) When siwtching a Thunderbird user running on a Fedora system (latest version of Thunderbird) Thunderbird couldn't see his mail folders even when the appropriate checkbox (Server Settings -> Advanced -> Show Only Subscribed Folders) was unchecked. Clearing out the IMAP Server Directory setting seemed to fix this, but the very next day, the folders were gone again and we've been unable since to get Thunderbird to see them. Using the same version of Thunderbird, running on Mac OS X 10.5.2 yields no such problem. Another problem with this same user involved a test wherein we created a new mail folder and then deleted it. The deletion caused an error message to be displayed (inferior folders, etc) but on the Mac OS X version no such error occurred and the folder was deleted. Investigating the protocol traces for Thunderbird showed that in the error case, it attempted to rename the deleted folder as a subfolder of the Trash folder (thus generating the error message) but on the Mac OS X version, it actually deleted the folder (which would seem to make more sense). The settings pertaining to the Trash folder are the same on both clients. 2) When switching an Apple Mail.app user running on Mac OS X 10.4.11 (Tiger) at the latest patch level, things appeared to work fine, and then the user mentioned that no mail was showing up in her inbox. Closing and restarting Mail.app appeared to fix that temporarily. She normally keeps a large number of messages in her inbox (approximately 7000+) and receives a large number of messages each day (several hundred). In this case, the Postfix mail logs showed that mail was being received, and the procmail delivery log for this user showed that procmail was putting the mail in her inbox, yet Mail.app was not indicating the presence of new mail (until it was restarted). Also Mail.app became very very slow at startup and shutdown (taking several minutes as compared to a few seconds normally). We've had no problems so far with another Tiger Mail.app user (but his inbox is considerably smaller) and no problems yet with converting a Eudora user running under Windows, but this is a stumbling block in our efforts to convert to dovecot since we'd hoped to be able to switch users over fairly easily (just by changing the port address mostly). While these woud seem to be client problems at first glance, the common factor of course is dovecot. There are no problems with any of these clients using UW-IMAP. I'm hoping that perhaps there are some readers of this list that might have seen similar problems and know of solutions, or could point me to some ways of debugging these problems (with Thunderbird I can at least debug IMAP protocol exchanges, but since dovecot doesn't log IMAP exchanges for specific IPs and since the socket connections are all via STARTTLS I can't use tcpdump so I'm kind of at a loss for how to track these things down short of patching the dovecot code to put in tracing messages). Any suggestions would be appreciated (and would help us complete our conversion to dovecot). Michael Durket

[Dovecot] Dovecot / FreeBSD / Nfs mailstore / Index=memory
by Xavier Beaudouin 19 Mar '08

19 Mar '08

Hello, I have recently changed imap from Courier-imap to dovecot because of serial problems with courier-imap, I have being forced to do it very quickly... and without extensives tests. I have 3 mails servers (freebsd based) behind a load balancer and a nfs mailstore on a netapp. On my first tests I have setup the index into some nfs shared mount, but it seems that some imap clients are going mad when deleting files (mostly because they do open some new imap connection and the index was not clean) so I have changed index to memory. This has fixed one of my problems. Now I have some strange problems is that NFS activity passed from about... 5mbps to more than 70Mpbs... Is there any reasons about that ? OS: FreeBSD 6.2-p11 / x86 Dovecot : 1.0.13 (freebsd ports) Auth: ldap based Nfs mail spool : filer:/vol/vol0/mail /var/mailusers nfs rw,nfsv3,mntudp,bg,noatime,nolockd 0 0 Thanks, /Xavier

If you want to have postfix authentificate from the same Database as Dovecot, you need it, but otherwise I do not see no relation. Or do you installed some script, that checks mails for Groupware-related ones and act upon them immediately? I cannot help you with Postfix. For shared resources you'll need yet another, shared account or look into the ACL plugin. KOrganizer even supports imap URLs natively, I saw right now.

[Dovecot] Missing folders after converting from Courier imap to dovecot
by M. Bobkiewicz 19 Mar '08

19 Mar '08

Hi, I?ve searched around for my problem but couldn?t find a solution. My setup: Centos 5.1 with postfix 2.5.1 (from source) and dovecot 1.0.10 (from source). I?m coming from an old Trustix 2.2 box with postfix 2.2.x and Courier imap with Maildir format mailboxes. For testing I?ve copied over some of the mailboxes from the old machine. After logging in to the new machine with Thunderbird only the incoming and trash folders appear in the Thunderbird sidebar all the rest are not showing up. When you send an email the sent folder appears with all mails this account has sent from the old machine, same with drafts etc. Access a folder directly and it will appear with all it?s content. This is some kind of nasty if you have to do this for several hundred folders. I?ve tried to fix the problem by changing the namespace private parameter "prefix" to ".". Also tried to rename courierimapuiddb to dovecot-uidlist. Both tricks don?t work. Unfortunately I can?t find the mentioned courier-dovecot-migrate.pl, maybe this would help... Any help and suggestion would be welcome. Best regards, Mike

[Dovecot] problems with postfix->procmail->deliver
by Andy Greenwood 19 Mar '08

19 Mar '08

Hi all. I'm relatively new to Dovecot, but I really like what I'm seeing so far. I have one problem that I was hoping you could help me with though. I use Postfix for my mail server, then pass that on to procmail for filtering, and finally to deliver to put the mail in the appropriate Maildir folder. However, this isn't working. Postfix passes the mail to procmail correctly, but procmail is failing when it tries to call deliver. My system-wide procmailrc matches the lower one shown here: http://wiki.dovecot.org/procmail?highlight=%28procmail%29 which uses deliver. My personal ~/.procmailrc is of similar format :0 * ^List-id:.<beginners.perl.org> #.perl/ | $DELIVER -m perl :0 * ^Sender:.owner.freebsd-\/[^@]+@FreeBSD.ORG { LISTNAME=${MATCH} :0 * LISTNAME??^\/[^@]+ # .freebsd-${MATCH}/ | $DELIVER -m freebsd-${MATCH} } :0 * ^Sender:.owner-cvs-all@freebsd.org #.cvs-all/ | $DELIVER -m cvs-all :0 * ^Delivered-To: greenwood.andy+combackup(a)gmail.com #.work/ | $DELIVER -m work :0 #$HOME/Maildir/ | $DELIVER However, my procmail logs show this error message for every message that comes through: Fatal: destination user parameter (-d user) not given I can see that the variable $DELIVER doesn't use the -d parameter, but I'm not sure on how I would specify the value in a multi-user system. I know I could just use deliver directly from Postfix, but I really want to use the filtering capabilities of procmail. If you need any additional information, just let me know. Thanks in advance for any help you can give, and big thanks for this great piece of software! Andy Greenwood

Hi everyone! I want to manage mail server resource part (like it can CGP) and with it I have one question. Is any way to limit overall max simultaneous connections to imap/pop3 server from one(each) host, except use iptables/ipfw and so on? Like a patch to dovecot or, maybe, it can be released in future versions? I know about mail_max_userip_connections in dovecot 1.1 but it can't limit hosts this way. Thank you.

[Dovecot] Invalid quota rule using "backend"
by Laurento Frittella 19 Mar '08

19 Mar '08

Using a quota rule like "quota_rule = *:backend=1073741824S" (I'm testing it statically but the value is on LDAP) I receive an an error: Fatal: IMAP(...): Quota root QUOTA: Invalid rule: *:backend=1073741824S Accordingly with the wiki page http://wiki.dovecot.org/Quota/New "Backend-specific configuration currently is used only with Maildir++ quota backend. It means you can have the quota in Maildir++ format (e.g. "10000000S")." so I think it should work. What's wrong? Cheers, Laurento

[Dovecot] xexec and dovecot 1.1
by subscriber＠viliar.net.ru 19 Mar '08

I'll test very interesting plugin xexec. It seems very nice and can be used in many things. It's compiled perfect with dovecot 1.0, but certanly not with dovecot 1.1. It's stopped with next error: In file included from cmd-xexec.c:30: xexec.h:8: error: expected specifier-qualifier-list before 'array_t' cmd-xexec.c: In function 'cmd_xexec': cmd-xexec.c:134: error: 'array_t' undeclared (first use in this function) cmd-xexec.c:134: error: (Each undeclared identifier is reported only once cmd-xexec.c:134: error: for each function it appears in.) cmd-xexec.c:134: error: expected ';' before 'union' I found, that in dovecot 1.1 has been changed some of functions of array init and so on. I'm not programmer :(, just a system admin., but first of all have to check it and trying to resolve by myself. According examples in ../../lib/array.h I removed array_t and this code is seems ok: xexec.h struct xexec { ARRAY_DEFINE(setups, struct xexec_setups *); }; and also here: cmd-xexec.c ARRAY_DEFINE(command, char *); After, errors cames with cmd-xexec.c: In function 'cmd_xexec': cmd-xexec.c:144: warning: passing argument 4 of 'client_read_args' from incompatible pointer type cmd-xexec.c:159: warning: assignment from incompatible pointer type cmd-xexec.c:180: warning: implicit declaration of function 'ARRAY_CREATE' cmd-xexec.c:180: error: expected expression before 'char' As I understand, it is because of (from changelog) Replaced ARRAY_CREATE() macro with [ipt]_array_init() macros. The macro has no side effects so it might as well be lowercased. I have look at the array.h, but can't find appropriate function in list of array_create,i_array_init,p_array_init,t_array_init. Should I just forget about it, until someone adapts code for dovecot 1.1, or maybe it no so complex, as looks? Thank you.

[Dovecot] Remote resources in kde-pim
by Anne Wilson 18 Mar '08

18 Mar '08

For some time I have been using dovecot to serve imap mail on my LAN. Now I want to add my diary and addressbook in kde-pim. I have got the docs from the kde site, but they talk about cyrus, and I'm not able to translate some bits of the instructions into dovecot ones. For instance, "At cyrus level (in the PC that runs IMAP server cyrus, with cyrus tools), we first need to add the user mary, so it's an IMAP recognised user, and create an IMAP folder for her" Can anyone give me a kickstart on this? On the server box I can see the dimap calendar resource and addressbook resource, so I now need to be able to tell it to allow certain users to access it. This is where I'm coming unstuck, and it looks as though no-one on the kde-pim list has done this with dovecot. Anne

Dovecot does not escape TAB characters in passwords when saving them, which might allow for argument injection in blocking passdbs such as MySQL, PAM or shadow (CVE-2008-1218). Impact ====== Remote attackers can exploit the first vulnerability to disclose sensitive data, such as the mail of other users, or modify files or directories that are writable by group via a symlink attack. Please note that the "mail_extra_groups" setting is set to the "mail" group by default when the "mbox" USE flag is enabled. The second vulnerability can be abused to inject arguments for internal fields. No exploitation vectors are known for this vulnerability that affect previously stable versions of Dovecot in Gentoo. Workaround ========== There is no known workaround at this time. Resolution ========== All Dovecot users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/dovecot-1.0.13-r1" This version removes the "mail_extra_groups" option and introduces a "mail_privileged_group" setting which is handled safely.

[Dovecot] A tail of joy...
by Curtis Maloney 18 Mar '08

18 Mar '08

So, I _finally_ got the time to upgrade from 0.99.14 ... which I told myself I'd upgrade from once 1.0 was released... (yep, I've been _that_ busy :) So I read the Wiki page on 0.99->1.0 transition, and went through the config file - for all of about 5 or 10 minutes. I logged in at 11pm when nobody else should be using it, restarted dovecot with the new version, and logged in. Snap snap snap went my folders opening.. wow, so fast! And as I got into work this morning... nobody knew a thing. If I hadn't asked a few people to let me know, nobody would have known a thing. My thanks to you, Timo. Thank you for making my life easier. -- Curtis Maloney cmaloney(a)cardgate.net

[Dovecot] Can the LDA deliver email marked as read?
by Kyle Wheeler 18 Mar '08

18 Mar '08

Hello, One of my users wants to be able to deliver email (e.g. via a procmail script) and mark it *read* when it's delivered. We use Maildir as our mail storage format. I have a bit of a hack script put together that will do it by directly manipulating the Maildir (it delivers the email using safecat, and then renames the file into the "cur" directory with the necessary flags appended to the file name), but this is a hack at best, and has the problem that if Dovecot is monitoring the file, it could potentially fail to work---there is a race between delivery and renaming. I've been slowly moving our site in the direction of using the Dovecot LDA to deliver mail. Is there a way (via a plugin, maybe?) to get the LDA to mark mail as "read" when it is delivered? ~Kyle -- He who dares not offend cannot be honest. -- Thomas Paine

In file 'deliver.c' on line 812 , there is a function named 'deliver_mail', see below: deliver_mail(storage, mail, destination, mailbox) I couldn't find out where is this function defined and how it was linked. Thank u for your help.

[Dovecot] current quota in mysql issue

hi all, i have a problem with storing the current quota in mysql. the configuration of the dictionary quota mostly looks like the example from the wiki. the dirsize quota limit is read correctly from the user_query, but nothing stored with quotadict in the quota table. i wonder that there is nothing like a "dict" in the logfile. did i configured anything wrong? regars stefan logfile from a imap login: Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): Effective uid=150, gid=8 Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): Loading modules from directory: /usr/lib/dovecot/modules/imap Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): Module loaded: /usr/lib/dovecot/modules/imap/lib01_quota_plugin.so Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): Module loaded: /usr/lib/dovecot/modules/imap/lib02_imap_quota_plugin.so Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, subscriptions=no Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): maildir: data=/var/vmail/mydomain.de/me/Maildir Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): maildir: root=/var/vmail/mydomain.de/me/Maildir, index=/var/vmail/mydomain.de/me/Maildir, control=, inbox= Mar 15 14:12:18 mx01 dovecot: IMAP(me(a)mydomain.de): dirsize quota limit = 20000000kB Mar 15 14:12:18 mx01 dovecot: imap-login: Login: user=<me(a)mydomain.de>, method=PLAIN, rip=10.1.1.147, lip=10.1.1.146 here is my current config: package from debian etch (1.0.rc15) ### # file dovecot.conf disable_plaintext_auth = no base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s protocol imap { listen = mx01.int.example.net:143 ssl_listen = mx01.int.example.net:993 } protocol pop3 { listen = mx01.int.example.net:110 ssl_listen = mx01.int.example.net:995 } log_timestamp = .%Y-%m-%d %H:%M:%S . syslog_facility = mail ssl_cert_file = /etc/ssl/example.net/mailserver/mail-cert.pem ssl_key_file = /etc/ssl/example.net/mailserver/mail-key.pem ssl_ca_file = /etc/ssl/example.net/mailserver/ca.pem ssl_parameters_regenerate = 168 verbose_ssl = no mail_extra_groups = mail mail_debug = yes auth_verbose = no auth_debug = no auth_debug_passwords = no first_valid_uid = 150 last_valid_uid = 150 first_valid_gid = 8 last_valid_gid = 8 maildir_copy_with_hardlinks = yes protocol imap { login_executable = /usr/lib/dovecot/imap-login mail_executable = /usr/lib/dovecot/imap imap_client_workarounds = outlook-idle imap_max_line_length = 65536 mail_plugins = quota imap_quota } protocol pop3 { login_executable = /usr/lib/dovecot/pop3-login mail_executable = /usr/lib/dovecot/pop3 mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)mydomain.com sendmail_path = /usr/lib/sendmail auth_socket_path = /var/run/dovecot/auth-master mail_plugins = cmusieve quota } auth_username_translation = %Lu auth default { mechanisms = plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb sql { args = /etc/dovecot/dovecot-sql.conf } user = nobody socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = vmail group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } namespace private { separator = / prefix = inbox = yes } plugin { quota = dict::: proxy::quotadict } dict { quotadict = mysql:/etc/dovecot/dovecot-sql-quota-dict.conf } ### # file dovecot-sql.conf driver = mysql connect = host=mx01.int.example.net dbname=db_mail user=dovecot password=******** default_pass_scheme = PLAIN user_query = select concat('/var/vmail/%d/%n/Maildir') as home, concat('maildir:/var/vmail/%d/%n/Maildir') as mail, 150 as uid, 8 as gid, quota from qry_dovecot where user = '%u' password_query = select user, password, concat('/var/vmail/%d/%n') as userdb_home, concat('maildir:/var/vmail/%d/%n') as userdb_mail, 150 as userdb_uid, 8 as userdb_gid from qry_dovecot where user = '%u' ### # file dovecot-sql-quota-dict.conf connect = host=db01.int.example.net dbname=db_mail user=quota password==******** table = quota select_field = current where_field = path username_field = username (don't wonder about the different database hosts. mx01 is a readonly slave from db01)

[Dovecot] CONDSTORE + QRESYNC extensions
by Timo Sirainen 16 Mar '08

16 Mar '08

I wrote a mostly-working CONDSTORE support for Dovecot today. You can try it with: hg clone http://hg.dovecot.org/dovecot-condstore/ There are a few problems left: - STORE FLAGS.SILENT should be sending FETCH MODSEQ updates - When SELECTing a mailbox while CONDSTORE hasn't yet been enabled in the session, Dovecot returns a higher HIGHESTMODSEQ than what's used after CONDSTORE is enabled. This is because modseqs aren't tracked until client has told us that it wants them. So Dovecot doesn't waste time trying to figure out the correct HIGHESTMODSEQ.. Something probably should be done about this. - STORE (UNCHANGEDSINCE xx) doesn't work correctly. The full fix would require adding a new transaction log record type containing the modseq, but currently it doesn't even bother refreshing the mailbox state before checking what the modseqs are. The modseq numbers are calculated as: modseq = ((indexid + log_file_seq) << 32) | log_file_offset Where: - indexid = A growing unique index file ID, usually the same as the UNIX timestamp of index file creation. - log_file_seq = dovecot.index.log file sequence. When the .log is rotated to .log.2 the new .log file's sequence is increased (so indexid and log_file_seq uniquely identify a log file) - log_file_offset = offset in dovecot.index.log where the flag change record was written. The numbers are a bit large, but this way if index files are deleted the modseqs always grow (so nothing breaks), because the newly created index file will have a larger indexid. The modseqs are also stored to dovecot.index file in "modseq" extension records. The highest modseq is stored in header extension. QRESYNC would require keeping track of expunges. This could be implemented by just going through records in log files to find out what messages have been expunged since the given modseq (= log seq+offset). Although I'm not sure if it would be better to have a separate expunge log. To allow rarely (e.g. once a week?) syncing clients the .log files may have to be rotated less often, so they would take more space. Also reading through them to find expunges would be slower than reading a separate log having only expunges. But writing a separate expunge log would add extra writes and there's no guarantee that it's ever even read. Other than that QRESYNC should be easy to implement.

[Dovecot] Virtual mailboxes
by Timo Sirainen 15 Mar '08

15 Mar '08

Virtual mailbox support can be tested with: hg clone http://hg.dovecot.org/dovecot-virtualboxes/ The code is still pretty non-optimized and I've only done some small tests, but at least it appears to work. Messages can't yet saved to virtual mailboxes, but I was thinking that the first configured mailbox could be used as the save destination. Configuration goes like: mail_plugins = virtual namespace private { .. prefix = virtual/ location = virtual:~/virtual-boxes } ~/virtual-boxes then contains a filesystem-layout view of all virtual mailboxes. Virtual mailboxes are configured in "dovecot-virtual" files. For example for virtual/unseen you'd create ~/virtual-boxes/unseen/dovecot-virtual file: INBOX Other mailbox unseen So the format goes like: <mailbox name> [<more mailbox names>] <search rule> [<search rule continues>] [<another mailbox name>] [<another mailbox's search rule>] Currently mailbox name wildcards aren't supported. The search rules are defined in exactly the same way as IMAP SEARCH command. So a few examples: - all - unseen - or keyword $Label1 or keyword $Label2 $Label3 - from domain.org subject hello Each time the mailbox is synchronized the mailbox search is ran for all the configured mailboxes. For simple rules this should be pretty fast, but for e.g. body searches it's a bad idea. I'll fix this in future so that it'll do searches only for newly seen messages. Virtual mailboxes don't have dovecot.index.cache files. All mail accesses (except uid/flag/keyword) go through the real mailbox and its cache file is used/updated. Messages that no longer match the search rule aren't removed until mailbox is either reopened or EXPUNGE command is sent. This allows creating a virtual mailbox with unseen messages, but without the message getting lost immediately after it's opened. Although perhaps it would be useful for a virtual mailbox with only non-deleted messages .. Maybe I should make it configurable separately for each vmailbox. I guess that's all.

[Dovecot] Help! OT: Blackberry IMAP client suggestions/experience needed
by Stewart Dean 14 Mar '08

14 Mar '08

The CFO of our college, a most formidable man, had decided to go Blackberry and Something Functional Must Be Done. We've had some users who we've not supported (and things got better for them when we switched from UWIMAP to Dovecot). BB, of course, has their half-baked sorta-IMAP-compliant client (and we do NOT want the BB Enterprise Server) that persistently keeps grabbing the mailbox and breaking the mailbox lock, causing no end of grief for the secretaries (plural, more than one) would also work with the mailbox. 1) Does anyone have recommendations and experience with a genuine BB IMAP client? Googling shows up LogicMail.... 2) I have been avoiding the plunge in multiple-access mailbox and just let the early BB adapter users thrash but I suppose it is time to do what I can with DC. We are running 1.0.12 with mbox format. Would some kind person <grovel,grovel> tell me where I should start reading plus any warnings. BB DC experience info would be a big help. Our CFO has a legendary temper and I would like to get as much as possible right the first time out........... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Feature request: dovecot -d option to output only/all 'defaults' of current version
by Charles Marcus 14 Mar '08

14 Mar '08

It would be nice to be able to do 'dovecot -d' that outputs only/all of the 'default' values of the currently running version, regardless of what is explicitly set. Postfix currently has this option, and it is very useful for one thing... to compare settings that have been explicitly set to what would be the default values. I used this recently on a postfix install to remove a whole bunch of values that had been explicitly set, and therefore showed up when postconf -n command was issued - but that would have been the default values anyway had they not been explicitly set - thus providing a much cleaner postconf -n output. Thanks Timo for dovecot!! -- Best regards, Charles

[Dovecot] Hardlinking with Sieve
by Anders 14 Mar '08

14 Mar '08

I have a simple Sieve rule to protect me from accidentally deleting mail: fileinto :copy "backup"; Should I expect this backup to be hardlinked to the ordinary one? Obviously, that would make the backup be almost for free in terms of storage, but currently I do not see any linking. Using Maildir, by the way, and I have not touched the maildir_copy_with_hardlinks setting. TIA, Anders.

[Dovecot] A message, when moved by multiple clients with same account and same filters, can be duplicated by filters on destination imap folder.
by Diego Liziero 14 Mar '08

14 Mar '08

I'm still collecting user feedback after moving from uw-imap to dovecot development release 1.1.rc3. What said in the subject seems the obvious result of an improper configuration. Office emails are configured and accessed on multiple clients with the same automatic filters, and sometimes the filtered emails get duplicated on the destination folder. The fact is that this was perfectly working with wu-imap (without any duplication/triplication of emails). I'm looking if there is some workaround to keep this client misuse working with dovecot. Could an email have a sort of "primary key" that forbids it's duplication in the same imap folder? Regards, Diego.

[Dovecot] LDA log_path
by jalal 13 Mar '08

13 Mar '08

Hi all I've just transferred a server from one machine to another. The only remaining dovecot problem I have is that the dovecot deliver program isn't writing a log file. I have this in the conf file: protocol lda { ..... mail_plugins = cmusieve mail_plugin_dir = /usr/lib64/dovecot/lda ..... # setup log files: log_path = /var/log/dovecot-deliver.log } but that file doesn't get written. The dovecot.log and dovecot_info.log files do get written and I've tried creating/touching the deliver log, but that doesn't seem to help at all. If I don't create /var/log/dovecot-deliver.log it doesn't get created by dovecot. If I use 'log_path = /tmp/dovecot-deliver.log' the file will get created but will remain empty. Anyone have an idea on how I can track this down? I like to have logs :) dovecot 1.0.12, CentOS 5/64 bit on a Virtuozzo VPS. TIA

[Dovecot] imap sent-mail folder sometimes dosen't get updated when used by more than a mailer at the same time.
by Diego Liziero 13 Mar '08

13 Mar '08

Hi, I'm collecting users feedback of latest dovecot 1.1.rc3 development release. Some users are complaining that their sent mails sometimes don't get written to imap Sent-mail folder. It seems that all these users were using multiple istances of imap processes to read their mail (thunderbird+horde-imp, evolution+horde-imp or multiple thunderbird istances). No error message is written in dovecot.log, no user feedback in horde-imp/evolution. Only thunderbird says it can't update Sent folder. Has anyone had similar issues? Diego.

[Dovecot] outlook2003 fails sasl authentication
by Johan Hendriks 13 Mar '08

13 Mar '08

Hello all i have postfix running with dovecot-sasl and mysql as a backend. It all runs good. I run into trouble as where outlook 2003 fails to authenticate when sending e-mail. I have thunderbird outlook2007 and 2003 clients. The tunderbird and 2007 clients are working OK, the outlook2003 client get the relay access denied message. In the postfix log i see it is not initiating sasl they all use pop i use dovecot 1.0.13 this is my posfix part of sasl smtpd_sasl_auth_enable = yes smtpd_sasl_exceptions_networks = $mynetworks broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination permit smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth and this is my dovecot sasl part # dovecot SASL socket listen { client { # Assuming the default Postfix $queue_directory setting path = /var/spool/postfix/private/auth mode = 0660 # Assuming the default Postfix user and group user = postfix group = postfix } } Am i doing something wrong? I guess if it is not configured right outlook 2007 and thunderbird will fail also! regards, Johan Hendriks
