[Dovecot] case (non-)sensitivity for folder names
by Phil Howard 06 Jan '11

06 Jan '11

Is IMAP supposed to be case sensitive or case in-sensitive? It seemed it would be case sensitive because I've had different cases of folders. But today I found I had two folders "Spam" and "spam", with directories ".INBOX.Spam" and ".INBOX.spam" on the server. Messages existed in each directory on the server and they were different. The messages could be read from Evolution. However, the list of messages had info mixed up between the folders. I then selected all messages in one of the folders and trashed them (click on trash icon). Messages disappeared in BOTH folders. On the server, after a couple minutes delay, messages in BOTH directories were flagged "T". That doesn't seem right. But I don't know enough about what IMAP is supposed to do, or on which end the names of folders get remapped into directory names, to even guess which is messed up here. I do know Evolution keeps a track of what it thinks the folder has, because in the past I have just "rm -fr" on a folder directory and Evolution still showed each message in its list, although it could not access them. Anyone know what's the deal with that? Unfortunately, there seems to be no operation in Evolution to tell it to discard its own cache. I'm also wondering if life would be any better if I used Thunderbird. -- sHiFt HaPpEnS!

[Dovecot] courier-dovecot-migrate.pl maintaining order of pop3 uidl's
by Mark Zealey 05 Jan '11

05 Jan '11

Hi there, I've just been experimenting with the latest courier-dovecot-migrate.pl script and I notice that it favours keeping pop3 UIDL ordering rather than IMAP UID preservation. There is this comment (line 312): # POP3 clients may want to get POP3 UIDLs in the same order always. # Preserve the order even if it causes IMAP UIDs to change. Does anyone have details as to which clients this actually causes a problem with? If it's some really old software then perhaps we'd prefer to keep the imap UID's the same but change the POP3 UIDL ordering (not the UIDL numbering though of course) Thanks, Mark

[Dovecot] dovecot 2.0.8 defaults to require ipv6 ?
by Jan-Frode Myklebust 05 Jan '11

05 Jan '11

FYI it seems dovecot 2.0.8 fails to start on RHEL5 with IPv6 disabled ("alias net-pf-10 off" in modprobe.conf) unless one specify "listen = *". Not sure if this is a known problem, or just a hint that we should start enabling ipv6 on our mailservers... ;-) -jf

[Dovecot] Lazy expunge for performance ?
by Jan-Frode Myklebust 05 Jan '11

05 Jan '11

Some filesystems are quite slow at deleting files, so I'm wondering if anybody is using the lazy expunge plugin to implement a solution where expunged messages are moved to a separate directory structure within the same filesystem, and later deleted as a nighly batchjob ? Assuming expunge renames/moves messages, and don't do a copy + delete.. Does something like this make sense ? -jf

[Dovecot] dovecot + sendmail, what LDA setup?
by David Cake 05 Jan '11

05 Jan '11

I have an existing setup with sendmail, dovecot, on debian. I want to move LDA and move from using mbox to using Maildir. I have only 'real' users and aliases, no virtual users. What is a recommended, trouble free, LDA setup? procmail is of course on possibility, but I'd be unlikely ever to use any of its advanced features, just simple local mail delivery. I'd like to use deliver, but most of the dovecot as LDA sample configs I have seen seem to assume I am using it for virtual users. Advice? Pointers to a simple working setup for sendmail, dovecot, Maildir? Cheers David

[Dovecot] re-indexing moved mail
by Phil Howard 05 Jan '11

05 Jan '11

I have a huge block of email that was misdelivered into the wrong folder. Moving it where it should be is not just all from one folder to being all of another folder. Basically, the index files need to be rebuilt. Looking in the wiki I cannot find how to do this. It all seems to be about installation, and no administrative tools. Or would it be just as simple as delete certain index files and they would be automagically rebuilt? -- sHiFt HaPpEnS!

[Dovecot] Error copying >1 message to virtual mailbox
by Nicholas Riley 05 Jan '11

I created a virtual mailbox which maps to a single physical mailbox (in Dovecot 1.x I did this with a symlink but had intermittent problems with Dovecot 2.0 doing the same.) However, I can only copy one message at a time into the mailbox. If I try to copy more, I get: 7.16 UID COPY 48531:48532 !/Saved 7.16 NO [CANNOT] Can't save messages to this virtual mailbox whereas this works fine: 10.16 UID COPY 48531 !/Saved 10.16 OK Copy completed.

[Dovecot] Converting from Maildir - sdbox
by Marc Perkel 04 Jan '11

04 Jan '11

OK - I thought this was going to be easy. Maybe it is. I'm just not that good at reading directions. Trying to use dsync. Getting this error: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) Currently using maildir. The setup is as follows: mail_uid = mail mail_gid = mail mail_location = maildir:/vhome/%d/home/%n:INDEX=/imap-cache/%d-%n I don't have any namespace setting. Not quite sure what a namespace is or why I need one. This is what I'm trying to run: dsync -u marc(a)perkel.com backup sdbox:/email/%d/home/%n What I'm hoping to do is do a mass conversion while running. Then shut it down - do a second quick pass - and bring it up in sdbox format. Thanks in advance.

[Dovecot] dovecotpw missing (2.0.8)
by Kristina Clair 04 Jan '11

04 Jan '11

Hello, I just installed dovecot version 2.0.8 from the source tarball. After doing ./configure, make, and make install, I don't have the dovecotpw binary anywhere. It is not in /usr/local/bin or /usr/local/sbin where the other binaries are; I also did a find / for it and don't see it. Is there some configuration flag I'm missing? I read the flags in ./configure --help and nothing seems obviously applicable to me. Is there a cryptography library I could be missing? I have the libs installed for crypt, md5, etc. Thanks, Kristina

[Dovecot] namespaces and noselect

Hello, I am trying to use two namespaces to create an "archival" directory that is stored as mboxes (the rest of my tree is all stored as maildirs). However, when I add the second namespace, suddenly Dovecot starts emitting, in response to the LIST command, a second version of the INBOX that is marked as \NoSelect. Here are my namespac definitions... am I doing this wrong? namespace { list = yes hidden = no inbox = yes location = maildir:~/Maildir prefix = separator = / type = private } namespace { hidden = yes # do not list as a separate namespace list = no # inbox = no location = mbox:~/Maildir/Archive:LAYOUT=fs:INDEX=~/Maildir/ArchiveIndexes/ prefix = INBOX/Archive/ separator = / type = private } ~Kyle -- If you are going through hell, keep going. -- Winston Churchill

[Dovecot] Finally upgrading from v1.0.15 to v1.2.16 -- advice please
by Jan-Frode Myklebust 04 Jan '11

04 Jan '11

It's long over due, but now I finally plan on upgrading from v1.0.15 to v1.2.16 on our servers. Would appreciate any comments! We have 7 servers, all running of the same GPFS filesystem. Both maildirs and indexes are stored here. We use dovecot for POP/IMAP and deliver. Currently we're using mysql as authentication source, but want to move to using ldap instead. Can we upgrade one server at a time, or do we need to upgrade all servers at the same time ? http://wiki2.dovecot.org/Upgrading/1.1 says "Index files have slightly changed as well. Upgrading to v1.1 should go transparently, but moving back to v1.0 might again cause some errors." which makes me think we can't have both versions running against the same users ? Also, if we upgrade only one server, should we switch to "mmap_disable=no" on this one, or keep running with "mmap_disable=yes" on all servers ? "NFS users should now set mail_nfs_storage=yes and mail_nfs_index=yes." Does this apply to any shared/networked filesystems, and is this relevant for GPFS ? The sql queries we're doing now is: password_query = select U.Account as user,S.Password as password from Users U, UserSession S where U.Account=S.Account and U.Account='%u' user_query = SELECT 3000 as uid, 3000 as gid, concat(concat('maildir:', MailDir), concat(':INDEX=', replace(MailDir, '/usr/local/atmail/users', '/usr/local/atmail/users/indexes'))) as mail, concat('maildir:storage=', UserQuota) as quota FROM Users WHERE Account = '%u' I plan on doing ldap bind() for authentication: hosts = maildb3.example.net:389 auth_bind = yes ldap_version = 3 base = ou=people,o=%d,o=ISP,o=example,c=net deref = never scope = onelevel user_filter = (&(objectClass=altiboxperson)(uid=%n)) default_pass_scheme = SSHA but the user_query is a challenge.. In LDAP we have: uid = janfrode, ou=people,o=domain1.net,o=ISP,o=example,c=net mail = janfrode(a)domain1.net mailMessageStore = /usr/local/atmail/users/j/a/janfrode(a)domain1.net mailQuota = 1000000 domain = domain1.net userPassword = SSHA-string So, outside of the user_attrs we need: mail_uid = 3000 mail_gid = 3000 But I'm having a hard time understanding how I can use the ldap value mail=/usr/local/atmail/users/j/a/janfrode(a)domain1.net to translate into dovecot's "mail" containing both "maildir:" and "INDEX=". Does the below look correct ? user_attrs = mailMessageStore=mail=maildir:%$:INDEX=/usr/local/atmail/users/indexes/%1u/%1.1u/%u, mailQuota=quota_rule=*:storage=%$ i.e. will it point dovecot at: mail = maildir:/usr/local/atmail/users/j/a/janfrode@domain1.net:INDEX=/usr/local/atmail/users/indexes/j/a/janfrode@domain1.net quota_rule=*:storage=1000000 -jf

[Dovecot] Vpopmail + Expire Plugin
by Oliver Lehmann 04 Jan '11

04 Jan '11

Hi, I've changed my running qmail/vpopmail/procmail/courier-imap/sqwebmail installation to qmail/vpopmail/siege/dovecot/horde imp. So far, I've got everything running. Authentification with vpopmail as passdb is working, Mail delivery with siege into different Mail folders is working as well. One of the reasons why I switched to dovecot was the expire plugin and right now I'm trying to set it up but I don't get it to run. - I created a MySQL User as advised - I created a database and a table and granted SELECT, INSERT, DELETE, UPDATE privileges for that table to user dovecot # mysql -udovecot -p dovecot Enter password: mysql> desc expires; +--------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+-------+ | username | varchar(75) | NO | PRI | NULL | | | mailbox | varchar(255) | NO | PRI | NULL | | | expire_stamp | int(11) | NO | | NULL | | +--------------+--------------+------+-----+---------+-------+ 3 rows in set (0.00 sec) mysql> select * from expires; Empty set (0.00 sec) - I added the following lines to my dovecot.conf: dict { expire = mysql:/usr/local/etc/dovecot/dovecot-dict-sql.conf.ext } plugin { expire = Test expire_dict = proxy::expire } - I created the dovecot-dict-sql.conf.ext # cat /usr/local/etc/dovecot/dovecot-dict-sql.conf.ext connect = host=localhost dbname=dovecot user=dovecot password=XXXX map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } # - When restarting dovecot I had a dict error because the socket was owned by root. I changed that so the socket is owned by the user vpopmail. - Then I created a folder "Test" via IMAP for one of my accounts - Then I copied via Horde IMP (so via IMAP) a message to that new folder - I requeried dovecot.expires in my database and it is still empty - I enabled logging for my MySQL DB and with that I found out, that no connect with the "dovecot" user is made at all so of course the table is empty. - I created a siege rule to move a mail directly to that Test folder when a specific Subject is used. lda moves the mail on arrival but still no MySQL connection is made. I've read that doveadm -A must work to get the expire plugin workinj, but it does not: # doveadm search -A mailbox INBOX subject test doveadm(olivleh1): Error: User listing returned failure doveadm: Error: Failed to iterate through some users # The expire plugin is loaded on startup: Jan 04 11:35:50 imap: Debug: Loading modules from directory: /usr/local/lib/dovecot Jan 04 11:35:50 imap: Debug: Module loaded: /usr/local/lib/dovecot/lib20_expire_plugin.so When using doveadm I'm getting a strange error: # doveadm -v expire -A mailbox INBOX subject test doveadm(olivleh1): Fatal: Unknown command 'expire', but plugin expire exists.

[Dovecot] X-SAVEDATE & dync & doveadm expunge
by e-frog 04 Jan '11

04 Jan '11

Hello List, After moving the mail store via dsync backup to a different location the following command doveadm expunge -u user mailbox "Trash" savedbefore 10d deleted ALL mails in Trash instead of messages older than 10 days. It looks like X-SAVEDATE is somehow wrong... A fetch 1:* (internaldate x-savedate) * 1 FETCH (INTERNALDATE "28-Dec-2007 14:49:58 +0100" X-SAVEDATE "01-Jan-1970 01:00:00 +0100") A OK Fetch completed. ...while the ctime for this mail is as below: $ ls -lac -rw------- 1 vmail vmail 40851 2010-12-30 19:26 1198963359.P1256Q0M253583.ubuntu-test.localdomain,S=40851:2,S I was assuming that for the maildirs X-SAVEDATE is derived from the message ctime?

[Dovecot] Automatic Debian Dovecot repository now also includes amd64 binary packages.
by Stephan Bosch 04 Jan '11

04 Jan '11

Hi, I've recently significantly improved the automated Dovecot Debian package builder. At the beginning it only produced i386 binaries for Debian testing. A few weeks back I added a slave builder that builds packages for Debian stable. Today I have extended the slave builder with support for multiple architectures and I've added amd64 binaries to the repository. The master builder still builds packages for testing/i386 every hour. The slaves check for new source packages about 20 minutes later. Read the following wiki page for more information and read it carefully when you are considering to use these packages: http://wiki.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages Also, every day at four 'o clock in the morning, the latest source packages are uploaded to the openSUSE build service, which builds i386/amd64 binaries for several Ubuntu versions (experimental): http://download.opensuse.org/repositories/home:/sbosch:/ Regards, Stephan.

[Dovecot] Problem with requiring client certificates for external connections
by Frank Crawford 04 Jan '11

04 Jan '11

Folks, I'm trying to configure my dovecot installation to require client certificates for external/Internet connections, while still allowing my local network to not need certificates. This configuration is for Dovecot 2 (2.0.8 in Fedora 14), and I've tried to use the "remote" block to give different definitions for my local network vs the defaults. While most options seem to be set fine, if I set "auth_ssl_require_client_cert" to yes as the default, and reset it to no for my local network, dovecot still requests a client certificate and fails as one is not supplied. Am I correct that it can be reset in a "remote" block, or is it treated differently to other options? In fact do I have the configuration correct, as there doesn't really seem to be anything documenting "remote" or "remote_ip" or related items for Dovecot 2. Related to this, much of the documentation states that the variable is "ssl_require_client_cert", seems to be accepted by ignored, vs "auth_ssl_require_client_cert" which does have some effects. Also, in the configuration dump, it duplicates the netmask. The configuration is below, as generated with "dovecot -n". Regards Frank # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.36.1 x86_64 Fedora release 14 (Laughlin) ext4 auth_ssl_require_client_cert = yes mail_location = maildir:/var/spool/maildir/%u managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)crawford.emu.id.au ssl = required ssl_ca = </etc/pki/CA/cacert.pem ssl_cert = </etc/pki/tls/certs/dovecot.crt ssl_key = </etc/pki/tls/private/dovecot.key ssl_verify_client_cert = yes userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %v.%u } remote 203.16.204.0/24/24 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no } remote fdd2:7aad:d478:1::/64/64 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no } remote 2001:44b8:62:140::/64/64 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no }
