[Dovecot] Populating mailbox dir
by Mauricio Tavares 20 Jan '11

20 Jan '11

Let's say you created a (virtual) mail user but have not created the user mail directory. When you first try to access it, the mail directory is created and populated: ls -a /var/spool/vmail/domain.com/raub/ . dovecot.index.log dovecot-uidvalidity.4d375a39 tmp .. dovecot-uidlist new .Trash cur dovecot-uidvalidity subscriptions Who populates/creates the initial files and folders in the user mailbox? Dovecot? The mail client accessing it through imap? Elvis? If dovecot, is there a way to customize it a bit, so a few extra folders will also be thrown there?

[Dovecot] domain stripping
by PA 20 Jan '11

20 Jan '11

Hi, using dovecot 2.0 and I'm using a couple of user DBs, sql/prefetch and pam. Currently if the user logins with username@domain it authenticates off the sql DB and works fine. If the user logins with username with no @domain it fails on the sql lookup and succeeds on the pam user DB. However I was wondering if I can have another sql DB lookup that says when the user logins and fails against the first two user DBs, sql/pam db, to try this last sql user DB and appends a default domain to it, because the sql DB lists username with the domain. Currently I have all users login in with no realm on the older mail server and I wanted to migrate these users to dovecot 2.x with minimal impact and wanted to have the ability for these virtual users to login with and without a realm. Thanks paul.

[Dovecot] Problems with Upgrade from Courier
by Aaron Pettitt 20 Jan '11

20 Jan '11

I inherited a server from a previous employee. The server crashed so it was time to move everything over to another server. We have a web mail site and I installed everything running dovecot, postfix and roundcube. After I installed it, everything worked great when I created a new user. The new user could send and receive emails with no issues. I then copied the home directory over from the other server and ran the courier-dovecot migration script. It created the subscription files and the dovecot-uidlist files in each user (about 1000 total users). When I login as one of the existing users, it says that there is no mail in the mailbox. However, if I look at the user's cur and new folders, there is mail in those folders. If I send a new mail to the user, it does not show up in their inbox. If I look in their new folder, the new mail that I sent was delivered to that folder but it does not show up in their inbox. I've tried going to dovecot directly through telnet with the same results. I've been stuck for 2 days now so any help is greatly appreciated. Below is my dovecot.conf with all the comments removed. Thanks all! protocols = imap imaps disable_plaintext_auth = no log_path = '/var/log/dovecot/error.log' info_log_path = '/var/log/dovecot/info.log' log_timestamp = "%m/%d/%Y %H:%M:%S " #mail_location = maildir:~/ mail_location = maildir:/home/vmail/%d/%n/ mail_privileged_group = mail mail_debug = yes protocol imap { } protocol pop3 { } protocol managesieve { sieve_storage=~/sieve } protocol lda { log_path = /home/vmail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)mybridemal.com mail_plugins = cmusieve global_script_path = /home/vmail/globalsieverc } auth_verbose = yes auth_debug = no auth_debug_passwords = no auth default { passdb sql { args = /etc/dovecot/dovecot-sql.conf } args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } user = root path = /var/run/dovecot/auth-master mode = 0600 user = vmail #group = } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } }

[Dovecot] Bug found, assertion failed
by Tobias Daucher 20 Jan '11

20 Jan '11

Hi there, We're running dovecot 2.06, with mdbox. Following message was in our syslog: Jan 20 09:26:48 servername dovecot: [ID 583609 mail.crit] imap(user): Panic: file istream-limit.c: line 79: assertion failed: (v_offset <= lstream->v_size) The problem could be solved on client side, by just deleting the ImapMail-Folder in Thunderbird. Why? Thunderbird tried to move a message, that obviously wasn't there. Dovecot got killed and the message above was in the syslog. Connection was closed and Thunderbird told me the server is dead. Thunderbird tried this every few seconds, and there was no way to say thunderbird "stop try moving". So the only way was to delete thunderbirds mail cache. I think it would be very nice, if dovecot doesn't die, just because the client tries to move a message, which isn't there.

Go with a cluster filesystem such as OCFS or GFS2 and an inexpensive SAN > storage unit that supports mixed SSD and spinning storage such as the Nexsan > SATABoy with 2GB cache: http://www.nexsan.com/sataboy.php I can't speak for OCFS2, but after several years' experience with the filesystem I strongly recommend NOT using GFS/GFS2. Its locking model is incredibly slow (500 locks/second on a filesystem mounted with quotas enabled and noatime) and results in dire performance - plus there's a known crash vulnerability if files are repeatedly renamed in large directories (this bites us regularly...) GFS2 isn't an "enterprise" filesystem by any stretch of the imagination, despite what a number of enthusiastic salespeople might try to convince you of. We're lucky to keep the GFS servers up for more than a week at a time.

[Dovecot] Upgrading from 1.2 to 2.0
by list＠airstreamcomm.net 20 Jan '11

20 Jan '11

Greetings Dovecot mailing list! We are an ISP that recently migrated from Courier to Dovecot, and are looking at the next round of upgrades. Hoping that we could get pointed to some documentation or get a general list of best practices for an upgrade from 1.2.13 to 2.0.9. Our current environment consists of four Dovecot machines that share an NFS backend hosting POP and IMAP. Our biggest question is whether we can support a rolling upgrade from 1.2.13 to 2.0.9, or if it would need to be an all for one cut. Thanks in advance.

Cool, thank you Patrick! Must have missed that somehow. I put the setting in main.cf, "receive_override_options = no_address_mappings", right after 'content_filter' (running amavisd on a separate port) and it seems to have fixed the problem. -- Darek On Tue, Jan 18, 2011 at 7:05 PM, Patrick Westenberg <pw(a)wk-serv.de> wrote: > Darek M schrieb: > >> Anyone have an idea of what I should be looking at in a situation like >> this?

[Dovecot] Pigeonhole 2.2 build issue on arm
by Tom Talpey 19 Jan '11

19 Jan '11

When building Pigeonhole 2.2 for ARM, the following warnings are produced: uri-mailto.c: In function '_parse_hex_value': uri-mailto.c:139: warning: comparison is always false due to limited range of data type uri-mailto.c:145: warning: comparison is always false due to limited range of data type The problem is a test assuming that char is a signed type : static inline int _decode_hex_digit(char digit) { ... static bool _parse_hex_value(const char **in, char *out) { char value; // <<--- change to "int". if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; *out = value << 4; (*in)++; if ( **in == '\0' || (value=_decode_hex_digit(**in)) < 0 ) return FALSE; This is untested, but I changed the "char value" to "int value" to correct the signed comparisons. There are no warnings when building for x86 in either case, btw. Also, the two tests for "**in == '\0'" seem to be unnecessary?

[Dovecot] Problem with seeing mail after Upgrade from Courier
by apettitt 19 Jan '11

19 Jan '11

I created a new server for a webmail system because the old server crashed. When I created the server, I installed Dovecot and the old server had Courier. On the new server, I'm doing virtual users where the old one created system users. I moved all the folders over for all the users on to the new server and ran the Courier-Dovecot migration script. The files were created successfully with no issues. The issue I'm having now is that Dovecot is not seeing any mail in the user's directory. If I create a new user, it can send and receive mail with no problems. If I send an email to an existing user, it gets delivered to the new folder but dovecot does not see anything in the new folder. There is also mail in the curr folder that dovecot does not see. I'm using Roundcube as a webmail client but I've also tried using Telnet with the same results. Any ideas? -- View this message in context: http://old.nabble.com/Problem-with-seeing-mail-after-Upgrade-from-Courier-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)
by Darek M 19 Jan '11

19 Jan '11

Dovecot 1.2.11, using postfixAdmin 2.3 to manage, basically using the postfixadmin schema and sql queries during install. - If I set a forward for an account to go to a remote email address, no dupes. - If I set a forward for an account to go to an email address on the same system, I get a dupe in the inbox of the second address. So if account1(a)domain.com has account2(a)domain.com as a forward, account2@ receives two copies of the same message, completely identical, same message IDs, same md5 sum. If I add account3@ into the mix, account3@ will also receive two copies of each message. I will also get a duplicate if I forward mail to account(a)anotherdomain.com, where anotherdomain.com is also hosted on the same system. account1(a)domain.com receives one copy. Here is the Dovecot log: Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account1(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Postfix logs only show one delivery for each message, and since the headers aren't changed at all, I think the lda is at fault here. This is the entry for the account in the 'alias' table ======================== mysql> select * from alias where address='account1(a)domain.com'; +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | account1(a)domain.com | account1@domain.com,account2@domain.com | nyinet.com | 2010-11-28 18:07:40 | 2011-01-18 17:04:03 | 1 | Anyone have an idea of what I should be looking at in a situation like this? Does the 'goto' field look fine? -- Darek

by J4 18 Jan '11

Hi there, I changed postfix to pass email to spamassassin, and then deliver to dovecot LDA. It fails to deliver. The current entry in master.cf now reads: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} smtp inet n - - - - smtpd -o content_filter=spamassassin spamassassin unix - n n - - pipe user=nobody argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} This is the same as I had to afore I factored in spamassassin. The error message is this:- Jan 18 16:30:44 logout postfix/pipe[28952]: 56AE58230A: to=<test(a)test.info>, relay=dovecot, delay=0.01, delays=0/0/0/0.01, dsn=5.3.0, status=bounced (command line usage error. Command output: Fatal: Unknown argument: flags=DRhu Usage: deliver [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-n] [-s] [-e] [-k] ) Does anyone know which options I should have added to dovecot deliver?

[Dovecot] v2.0.9 released
by Timo Sirainen 18 Jan '11

18 Jan '11

http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz.sig I'm still lagging behind in my email, but I guess it's time to release v2.0.9 anyway. - Linux: Fixed a high system CPU usage / high context switch count performance problem - Maildir: Avoid unnecessarily reading dovecot-uidlist while opening mailbox. - Maildir: Fixed renaming child mailboxes when namespace had a prefix. - mdbox: Don't leave partially written messages to mdbox files when aborting saving. - Fixed master user logins when using userdb prefetch - lda: Fixed a crash when trying to send "out of quota" reply - lmtp: If delivering duplicate messages to same user's INBOX, create different GUIDs for them. This helps to avoid duplicate POP3 UIDLs when pop3_uidl_format=%g. - virtual storage: Fixed saving multiple mails in a transaction (e.g. copy multiple messages). - dsync: Saved messages' save-date was set to 1970-01-01.

[Dovecot] Question about indexes and maildir/sdbox/mdbox
by Javier de Miguel Rodríguez 18 Jan '11

18 Jan '11

Hello We are now running dovecot 2.0.9 with indexes in a ram disk and maildir storage in a test system. We have the following questions: - If there is a power outage / kernel crash, we will lose the content of ramdisk. We have tested that indexes are regenerated when a user logs in via imap, so e-mail access will be "slower" after a power outage / kernel crash, but everything should work as expected (TM). Are we missing something? - We are evaluating migrating from maildir to dbox. There are two alternatives: sdbox and mdbox. Reading about dbox in the wiki (http://wiki2.dovecot.org/MailboxFormat/dbox) we see that using a ram disk for indexes for mdbox is a really bad idea: /"Note that with dbox the Index files actually contain significant data which is held nowhere else. Index files for both *single-dbox* and *multi-dbox* contain message flags and keywords. For *multi-dbox*, the index file also contains the map_uids which link (via the "map index") to the actual message data. This data cannot be automatically recreated, so it is important that Index files are treated with the same care as message data files."/ So in mdbox we should not use a ramdisk for indexes. But what about sdbox? sdbox indexes work as maildir indexes? Are sdbox indexes bigger than maildir indexes? Thank you very much for your support Regards Javier

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by Dave 17 Jan '11

17 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

This is pretty much what I do with the mail domain I administer. I've set the INBOX with a modest quota, and a personal mail folder with a generous quota. I encourage users to keep their INBOX as a "working set", and archive the rest using any method they prefer. It forces users to process their Email (or at least their INBOX). and keeps packratting in check. Super-big INBOX quotas seem to encourage wasteful habits. I've helped some users clean out their mailboxes and was surpised at the amount of junk being kept for years and years. Apart from a few users moaning about their meager INBOX, this policy works out fairly well. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Virtual mailboxes do not look into subfolders
by Paul Provost 17 Jan '11

17 Jan '11

Hi all, I have virtual mailboxes set up as "Smart Folders" to show me messages tagged with certain keywords. For example: # ~/Maildir-virtual/fwp/dovecot-virtual File MailingLists/* KEYWORD @fwp Messages get picked up from the File mailbox, but not for the sub-mailboxes inside the MailingLists mailbox. What am I doing wrong? Wrong separator? And how can I debug this? Everything else is working fine. Thanks a lot! Paul

[Dovecot] vpopmail disabled services fix
by Calvin 17 Jan '11

17 Jan '11

I noticed that disabling services using vpopmail was not being recognized by dovecot. Using "vmoduser -swip user(a)domain.com" should disable all services, but both pop and imap logins were still allowed. After a bit of digging in the code and confirming with a few debug lines, it appears that lines 38 and 52 of src/auth/passdb-vpopmail.c are the issue (dovecot 2.0.8). These two lines do a strcmp on request->service. It appears that request->service is in lower case, but the comparison values are in upper case. Either updating the values to lowercase or using strcasecmp should fix the issue.

[Dovecot] mail to admin when quota exceeded
by Karolis Žvaigždinas 16 Jan '11

16 Jan '11

We're using Dovecot v1.2.15 LDA/IMAP/POP3+MySQL with quota plugin, quota_rule per-user size, quota_exceed_message and quota_warning on storage=90%%.with script. Everything is working as expected. But I've been asked to configure it the way, that when a user gets message, which would make his maildir over quota limit, notification go not only to sender, but also to postmaster(a)domain.com. Browsed wiki, mailinglist archive - couldn't find anything on that. Is there a way to implement such feature? And what about possibility to send a message to user, notifying him about rejected email "from: xxx(a)yyy.com" with "subj: blah blah" due to full mailbox? Such messages are small and would not take too much space. Thus the user would know what he misses, urging him to clean his mailbox. Thank you in advance. -- Karolis

[Dovecot] [PATCH] auth: Fixed mech_winbind_ntlm by using mech_winbind_auth_initial()
by Christian Wiese 16 Jan '11

16 Jan '11

Hi folks, attached is a trivial patch which is fixing Winbind/NTLM authentication in dovecot 2.0 series. The patch was made against 2.0.8 sources, but there should be no problem applying it onto HEAD, because 'src/auth/mech-winbind.c' wasn't touched for quite some time now ;) I tested the patch with a dovecot 2.0.8 running on linux, authenticating against a WindowsServer 2008R2 Enterprise using ntlm_auth/winbind (from current stable samba 3.5.6). I successfully tested NTLM authentication for IMAP and POP3 (with and without STARTTLS) using following MUAs for the test: - Thunderbird 3.1.7 (Linux X86-64) - Outlook Express 6.00 (Windows XP Pro Qemu-KVM) Cheers, Chris Patch Description: In changeset 9002 a new function named mech_winbind_auth_initial() was introduced, but only the mech_winbind_spnego module part was changed to finally use this function. The mech_winbind_ntlm module part was not properly adapted which leads to a non functioning NTLM authentication mechanism while using winbind, because it will never call the `ntlm_auth` helper. The simple fix is to replace mech_generic_auth_initial() with mech_winbind_auth_initial() as auth_initial "hook" when setting up the mech_winbind_ntlm module, like it is done in the mech_winbind_spnego module.

[Dovecot] dovecot lda and quota plugin with mysql
by J4 16 Jan '11

Dear all, I have postfix delivering to dovecot lda (via spamassinassin). I have configured the quota plugin, but it does not seem to respect the details in the quota table in mysql. The query I have used looks correct to me, and the user can connect to the database. I wonder if someone might put me straight on the misconfiguration.

[Dovecot] umask setting
by PA 16 Jan '11

16 Jan '11

Hi, I have a user called archive that gets a BCC of all incoming/outgoing email. I would like to have the email in the new/cur directories setup to be read only, is there a way to do this in dovecot 2.0.8. I know you can set the umask in the dovecot config but I believe this is a global setting. Thanks, Paul

[Dovecot] Rename public folders
by Burian, John 16 Jan '11

16 Jan '11

I've got a number of public mailboxes configured for my users. We pretty much have to use Entourage for a client, which insists on creating all new subfolders with the name 'Untitled Folder'. When they try to rename these subfolders with useful names, Dovecot returns A028 NO [CANNOT] Renaming not supported across non-private namespaces. I guess this is because renaming a subfolder could potentially break subscriptions for other users? Or is it a hard requirement from IMAP RFC? If the former, is the problem merely very complicated, but eventually fixable, or is it just intractable? We're using Dovecot 2.0.7 from the atrpms RPM, Redhat EL 5.0. The public mailbox namespace is configured with: namespace { type = public prefix = Public/ separator = / hidden = no list = yes inbox = no subscriptions = no location = maildir:/data/imapmail/public:LAYOUT=fs } -- John Burian Systems Programmer Battelle Center for Mathematical Medicine The Research Institute At Nationwide Children's Hospital 614-355-5686 John.burian(a)nationwidechildrens.org ----------------------------------------- Confidentiality Notice: The following mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

In the real world of an ISP, killing 99% of all spam before it hits the storage is unthinkable. We only block spam that is guaranteed to be unwanted, mostly based on technical facts that can't ever happen in normal email. But email that our scanning system flags as probable spam, is just that, probable spam. We can not just throw that away, because in the real world, there are always, and I mean always, false positives. It is unthinkable to throw false positives away. So we have to put these emails in a spam folder in case the user wants to look at it. We block about 40% of all spam on technical grounds, our total spam percentage is 90%, so still about 80% of all customer email reaching the storage is spam. > > But in other environments throwing away all probable spam may be perfectly fine.

Currently mostly in database servers, but our experiences have been good enough that we're slowly starting to add them to more systems as even boot drives. But we're not using them yet in email storage. Like Brad we're using Netapp filers because as far as I know they're one of the few commercially available HA filesystem companies. We've looked at EMC and Sun as well, but havent found a reason to move away from Netapp. In 12 years of netapp we've only had 1 major outage that lasted half a day (and made the front page of national news papers). So, understand that bit. Major outages make it to national news papers for us. HA, failover, etc are kind of important to us. > > So why not build something ourselves and use SSD? I suppose we could, but it's not as easy as it sounds for us. (your mileage may vary). It would take significant amounts of engineering time, testing, migrating, etc etc. And the benefits are uncertain. We dont know if an open source HA alternative can give us another 12 years of virtually faultless operation. It may. It may not. Email is not something to start gambling with. People get kind of upset when their email disappears. We know what we've got with Netapp. > > I did dabble in using SSD for indexes for a while, and it looked very promising. Certainly indexes are a prime target for SSD drives. But when the director matured, we started using the director and the netapp for indexes again. I may still build my own NFS server and use SSD drives just for indexes, simply to offload IOPS from the Netapp. Indexes are a little less scary to experiment with. > > So, if you're in the position to try out SSD drives for indexes or even for storage, go for it.

Hi, Since upgrading dovecot version (from somewhat ancient to 1.2.16), I see messages in the logs like these: Jan 15 00:55:17 srv0303 dovecot: POP3(obm03): fchown(/home/obm/obm03/mail/.imap/INBOX/dovecot.index.tmp, -1, 8(mail)) failed: Operation not permitted (egid=1033(obm), group based on /var/mail/obm03) I know that this is because the mailbox in /var/mail has ownership username:mail. However, in this setup this is intentional, and quota-related (quota on inbox is enforced by Exim, not Dovecot, and kernel does group-quota but not for group mail). Also, group read rights for group mail are intentional. >From what I read on this list, it has something to do with shared folders. I did not (at least it wasn't my intention) configure users' inboxes as shared folders. So, is there a way to disable these log messages, or, to disable Dovecot's attempts to try to change the owner/group of the index/cache/log files when these are inside the user's private ~/mail folder? More specifically, is there a way to do this without changing anything to users' inbox permissions? Thanks, Maarten

[Dovecot] fs quota backend bug
by Jan Škoda 16 Jan '11

16 Jan '11

Hi, I maintain postfix mailserver with sudo enabled dovecot LDA using multiple uids. I want to enforce quotas per-unix-user (which can have multiple domains with multiple emails set up using postfixadmin), so I have set up a FS quota backend with imap_quota plugin. Unfortunately, the quota appears to work (when i disable chrooting) according to dovecot-info.log, but doesn't send anything over IMAP. I found several topics related to this bug in this mailing list, but without any reply. All files in Maildir belong to unix-user ofight (1042) # sudo -u ofight quota Disk quotas for user ofight (uid 1042): Filesystem blocks quota limit files quota limit /dev/mapper/vg-home 2058888 2150400 2365440 35432 537600 591360 Info: Loading modules from directory: /usr/lib64/dovecot/imap Info: Module loaded: /usr/lib64/dovecot/imap/lib10_quota_plugin.so Info: Module loaded: /usr/lib64/dovecot/imap/lib11_imap_quota_plugin.so Info: Effective uid=1042, gid=102, home=/home/vmail/ofight.org/team@ofight.org/ Info: Quota root: name=Kvota backend=fs args=mount=/home Info: Namespace: type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes Info: maildir: data=/home/vmail/ofight.org/team@ofight.org/ Info: maildir++: root=/home/vmail/ofight.org/team@ofight.org, index=, control=, inbox=/home/vmail/ofight.org/team@o fight.org Info: fs quota add storage dir = /home/vmail/ofight.org/team(a)ofight.org Info: fs quota block device = /dev/mapper/vg-home Info: fs quota mount point = /home Info: fs quota mount type = jfs Info: Namespace: type=private, prefix=INBOX., sep=., inbox=no, hidden=yes, list=no, subscriptions=yes Info: maildir: data=/home/vmail/ofight.org/team@ofight.org/ Info: maildir++: root=/home/vmail/ofight.org/team@ofight.org, index=, control=, inbox= Info: Namespace : Using permissions from /home/vmail/ofight.org/team(a)ofight.org: mode=0700 gid=-1 Info: Disconnected: Logged out bytes=133/834 Part of IMAP conversation captured with wireshark: getquotaroot "INBOX" QUOTAROOT "INBOX" Ok Getquotaroot completed Part of strace: read(0, "357 getquotaroot \"INBOX\"\r\n", 1259) = 26 stat("/home/vmail/ofight.org/team(a)ofight.org/tmp", {st_dev=makedev(253, 2), st_ino=475158, st_mode=S_IFDIR|0700, st_nlink=2, st_uid=1042, st_gid=102, st_b lksize=4096, st_blocks=0, st_size=1, st_atime=2011/01/16-10:07:59, st_mtime=2011/01/16-10:07:59, st_ctime=2011/01/16-10:07:59}) = 0 stat("/home/vmail/ofight.org/team(a)ofight.org", {st_dev=makedev(253, 2), st_ino=475157, st_mode=S_IFDIR|0700, st_nlink=11, st_uid=1042, st_gid=102, st_blks ize=4096, st_blocks=16, st_size=4096, st_atime=2009/05/18-12:07:57, st_mtime=2011/01/16-11:36:32, st_ctime=2011/01/16-11:36:32}) = 0 stat("/home/vmail/ofight.org/team(a)ofight.org", {st_dev=makedev(253, 2), st_ino=475157, st_mode=S_IFDIR|0700, st_nlink=11, st_uid=1042, st_gid=102, st_blks ize=4096, st_blocks=16, st_size=4096, st_atime=2009/05/18-12:07:57, st_mtime=2011/01/16-11:36:32, st_ctime=2011/01/16-11:36:32}) = 0 stat("/home/vmail/ofight.org/team(a)ofight.org/dovecot-shared", 0x3f5aa9cf710) = -1 ENOENT (No such file or directory) stat("/home/vmail/ofight.org/team(a)ofight.org", {st_dev=makedev(253, 2), st_ino=475157, st_mode=S_IFDIR|0700, st_nlink=11, st_uid=1042, st_gid=102, st_blks ize=4096, st_blocks=16, st_size=4096, st_atime=2009/05/18-12:07:57, st_mtime=2011/01/16-11:36:32, st_ctime=2011/01/16-11:36:32}) = 0 stat("/home/vmail/ofight.org/team(a)ofight.org", {st_dev=makedev(253, 2), st_ino=475157, st_mode=S_IFDIR|0700, st_nlink=11, st_uid=1042, st_gid=102, st_blks ize=4096, st_blocks=16, st_size=4096, st_atime=2009/05/18-12:07:57, st_mtime=2011/01/16-11:36:32, st_ctime=2011/01/16-11:36:32}) = 0 access("/home/vmail/ofight.org/team(a)ofight.org/cur", W_OK) = 0 setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 write(1, "* QUOTAROOT \"INBOX\"\r\n357 OK Getq"..., 53) = 53 # 1.2.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-hardened-r31 x86_64 Gentoo Base System release 2.0.0 jfs base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: imap imaps pop3 pop3s managesieve listen: *, [::] ssl_cert_file: /etc/apache2/ssl/server.pem ssl_key_file: /etc/apache2/ssl/server.key disable_plaintext_auth: no shutdown_clients: no 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 login_executable(managesieve): /usr/libexec/dovecot/managesieve-login login_greeting: Dovecot ready.

I've checked my setup - the guest is not set to sync with the VMware host. NTP is running with local clock server commented out & 'tinker panic 0' set. It sounds like this is not a Dovecot issue so I'll stop posting to this list now and seek help elsewhere. What negative effects to Dovecot would I expect to see where the system clock is constantly changing?

[Dovecot] Check if a message has attachments
by Antoine Nguyen 14 Jan '11

14 Jan '11

Hi all, my question is not specific to Dovecot but to the IMAP protocol in general. I'm working on a web based software that provides a simple webmail ( http://modoboa.org/) I'm wondering what would an efficient way to detect if a message (or a group of messages) has attachments. I know it certainly consists in checking for specific MIME constructions but how to achieve that without fetching the whole body for each message? Thanks in advance, Antoine Nguyen

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by David Salisbury 14 Jan '11

14 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

Thanks, I've read through that document a couple of times now & I'm fairly sure my system 'ticks all the boxes' yet the warning messages continues. I can see no noticeable time discrepancy when I do periodic time checks from the command line comparing against another system's clock - certainly not 2 minute error margin Could this be a time mismatch between imap client & server?

[Dovecot] email addresses as usernames with Kerberos
by Peter Mogensen 14 Jan '11

14 Jan '11

Hi, I was trying out Kerberos authentication with som sample users for Dovecot and stumbled into this problem: The user names are of the form local-part@domain, so the Kerberos principal becomes "local-part\@domain@REALM". But it seems Dovecot (1.2.9) doesn't understand that syntax. Looking at the 2.0.8 sources I guess it's not supported. But isn't this a valid Kerberos principal? Is it a bug, or a missing feature or is there a special reason for not supporting it ? kind regards, Peter

Re: [Dovecot] Making shared folders "unmovable"

Well, I just noticed this in my logs after I re-loaded the latest Dovecot config I tried: Jan 13 15:09:45 mail dovecot: SIGHUP received - reloading configuration Jan 13 15:09:45 mail dovecot: read(imap dump-capability process) failed: Interrupted system call Jan 13 15:09:45 mail dovecot: Invalid configuration, keeping old one Jan 13 15:09:45 mail dovecot: child 2085 (unknown) returned error 82 (Internal logging error) It's apparently been doing this every time I've reloaded the config, so this is probably why none of my changes with the ACLs are working. :/ Any thoughts on what could be causing this kind of error?? Does that error just basically mean something's set wrong somewhere in dovecot.conf? David

The 3.x branch is rock solid. There have been no crashes (yet!) Would DRBD + GFS2 work better than NFS? While NFS is simple, I don't mind experimenting with DRBD and GFS2 is it means fewer problems?

[Dovecot] Denying authentication
by Romer Ventura 13 Jan '11

13 Jan '11

Hello, I've been running dovecot for over 3 years now and it works with no problems. I have it setup so that it authenticates users against Active Directory via LDAP and so far no problems. What I would like to know is if there is any way that I could deny access for users trying to access email via cellphones or email clients outside the company. I can close everything since there are a few users that need to get emails from outside the company via cell phone of email clients. I was thinking if there was a way to lets say create a group in AD named: "remote-email" that will allow connection and authentication from any network, any user not in that group will only be able to authenticate if the source is 192.168.xx.xx/24. Is this possible? Maybe not with Dovecot, but maybe someone else has any ideas..? Thanks -------- Romer Ventura

[Dovecot] Making shared folders "unmovable"
by Dave 13 Jan '11

13 Jan '11

I have set up an area of shared folders with Dovecot 1.2 that is accessed by several people (by way of one account, and everyone who logs in sees these same folders), and the only problem with this setup is that occasionally somebody moves one of the folders underneath another folder or somewhere else in the folder structure, and this sometimes disrupts some automatic procmail filters and the like. Is there a way to keep folders in a shared setup such as this "static" or "unmovable" so that the users can't disrupt the structure? Like, where the folder structure itself can't be changed, but new messages can still come in to the folders? David

[Dovecot] How do folk . . . Aggregate system mail from LAN machines?
by Ron Leach 12 Jan '11

12 Jan '11

List, good evening, Running Dovecot for external email, but not yet worked out how (best) to aggregate 'system' mail from other machines on the LAN. By system mail, I mean mails generated by the OS or by applications, and addressed to root, or 'some admin user', etc. Ideally, these would be seen by 'root' or 'some admin user' or whoever on our existing Dovecot/IMAP system. Our scale is not large, we only have 5 servers on the LAN doing various things. I wondered how other Dovecot users do this. I've thought of 3 possibilities: 1. Install Dovecot on each LAN machine, and use Fetchmail to retrieve the messages using POP so that local mail stores were emptied. 2. Perhaps, use a 'forwarding' mechanism of some sort on each LAN machine, but that would require an MTA on each LAN machine, would it not? 3. I wondered whether /etc/alias, mentioned in a recent post by Simone Caruso, might help though again, presumably, requiring an MTA on each LAN machine. What do you do? regards, Ron

[Dovecot] Question about lda & auth_socket_path
by Jahnke-Zumbusch, Dirk 12 Jan '11

12 Jan '11

Hi all, storing e-mails (using postfix) via dovecot-lda fails and I assume this is related with a auth_socket configuration problem. But I am at a dead end, so perhaps anybody has got a hint for me: This is dovecot-2.0.8 on Solaris 10: 10-auth.conf and its include: ----------------------------- ... userdb { driver = static args = uid=104 gid=104 home=/some/path/%u } Relevant parts of 10-mail.conf: --------------------------------- ... auth_socket_path = /var/run/dovecot/auth-userdb Relevant parts of 10-master.conf: --------------------------------- ...service auth { unix_listener auth-userdb { mode = 0644 user = vmail #group = } } service auth-worker { user = root } Relevant parts of 15-lda.conf: --------------------------------- ... protocol lda { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins } # ls -l /var/run/dovecot/auth-userdb srw-r--r-- 1 vmail root 0 Jan 12 15:49 /var/run/dovecot/auth-userdb Using dovecot-lda for mail delivery or doveadm for user inquirement fails: via debug_log_path: ------------------- Jan 12 16:04:14 auth: Debug: Loading modules from directory: /dovecot/code/dovecot-2.0.8/lib/dovecot/auth Jan 12 16:04:14 auth: Debug: passwd-file /store1/db/masterusers.passwd: Read 1 users Jan 12 16:04:14 auth: Debug: master in: USER 1 djahnke service=lda Jan 12 16:04:14 auth: Debug: password(djahnke): passdb doesn't support credential lookups Jan 12 16:04:14 auth: Debug: master out: FAIL 1 Jan 12 16:04:14 lda: Debug: auth input: via syslog: ----------- Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] auth: Error: static(djahnke): passdb doesn't support lookups, can't verify user's existence Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] lda: Error: user djahnke: Auth USER lookup failed Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.crit] lda: Fatal: Internal error occurred. Refer to server log for more information. When I use "allow_all_users=yes" everything works fine, so I think somehow the communication with the socket fails. I cannot see what I have missed :-( Any suggestions what I should look for / configure ?

[Dovecot] mail quota dovecot 1.2.15-3
by J4 12 Jan '11

12 Jan '11

Dear all, I am attempting to enforce quota with Dovecot 1.2.15-3 using LDA for deliver. I use smtp-source (postfix) to deliver large messages but the quota is never noticed. The webmail interface is Roundcube, and the admin is performed using Postfixadmin. I have not looked into the postfix portion for quota, yet. Is there something that I have missed from the configuration?

[Dovecot] Refilter Mailboxes via Sieve - Missing delivered-to header
by Dieter Knopf 12 Jan '11

12 Jan '11

Hello, i already read http://wiki.dovecot.org/HowTo/RefilterMail but it won't work here :( I have many old mails in my folders and need to refilter many of them. But there are many mails without a delivered-to-header. What can i do? Error: Configuration error: envelope_recipient specified header missing (delivered-to:1) Would be okay if getmail would just skip the mail, but it cancels. Not sure if there is any way around. This is the config: [retriever] type = MultidropIMAPSSLRetriever envelope_recipient = delivered-to:1 server = foo port = 993 username = foo password = foo mailboxes = ("INBOX.REFILTER",) move_on_delete = INBOX.trash [destination] type = MDA_external path = /usr/lib/dovecot/deliver arguments = ("-e", "-f", "%(sender)", "-d", "%(recipient)") user = vmail group = vmail [options] delete = true recieved = false delivered_to = false verbose = 2 I'm using virtual users, so i must use Multidrop. Thanks

[Dovecot] Connection queue full on my directors
by Jan-Frode Myklebust 11 Jan '11

11 Jan '11

I finally upgraded to v1.2.16 on my backend servers, with ldap instead of previously mysql, and put a couple of dovecot v2.0.8 directors in front of them (used haproxy previously). It seemed to work OK initially, but after a few hours we got bit by "Connection queue full" problems on the directors. So I now set default_process_limit=512 and also: service anvil { client_limit=1027 } since dovecot said that was now required. Things seems to be working, but I'm afraid default_process_limit=512 is too low: $ ps -ef|grep dovecot/pop3-login|wc -l 192 $ ps -ef|grep dovecot/imap-login|wc -l 472 so looks like I'm quite close to hitting this limit for my imap logins. We will eventually put up some webmail servers (using imapproxy to keep connections alive), that will be connecting over these directors. Then we will expect to have a lot more active imap sessions over these directors. Should we just keep increasing default_process_limit, or per service process_limit, and follow dovecots warnings about client_limits for auth/anvil.. or will we be getting into other problems like running out of file descriptors? Are there any max'es we should expect to run into ?

[Dovecot] Dovecot - AllowGroups option
by Jacob Neergaard Pedersen 11 Jan '11

11 Jan '11

Hi, I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage. Services like proftpd have: "AllowGroup ftpgroup" sshd have "AllowGroups sshgroup" And samba have "valid users = @smbgroup" But I can't find the correct option in Dovecot (/etc/dovecot/dovecot.conf) Do anyone have the magic option or a workaround thats doesn't envolve maintaining seperate user databases and password? (I know its needed for samba but besides that) /Neergaard

[Dovecot] utility to copy/sync IMAP mailboxes
by Don Buchholz 11 Jan '11

11 Jan '11

Well, my Dovecot server (v2.0.8) is up and running, and now it's time to migrate mailboxes from the old mail server [Lotus Domino Release 5.0.8] running on Windows NT 4.0 [ancient -- been the mail server since Aug-2000]. I saw "dsync(1)" and thought my troubles were over. Only I can't figure out how to make it work with the NT/Domino server as a source for mailboxes. I guess dsync(1) works only in completely *nix environment. I've been trying the imapcopy.pl script from the IMAP Tools web page (http://www.athensfbc.com/imap_tools/) but it is having problems with Notes' choice of the backslash (\) character as a mailbox (namespace?) delimiter. Any suggestions for a stable, reliable (copy/duplicate/mirror/sync) tool that can do the job using only IMAP access? (No SSL support required.) Thanks in advance, - Don

[Dovecot] Max number of mail processes
by Patrick Nudo 11 Jan '11

11 Jan '11

Dovecot version 1.1.11. Error: Maximum number of mail processes exceeded (see max_mail_processes setting). I can't seem to get rid of these errors. I get batches of these errors about 4 or 5 times a day. I have a cron-job checking for the existence of this error and then I reboot dovecot when I see this error, but what is causing this error ? What I am reading on the Internet about this particular issue has not helped to resolve the issue. I would really like to know how many mail processes it thinks that it is using at any one instant in time. Is this possible ? Maybe then I can track the reason for the error.

[Dovecot] enforce STARTTLS on port 110 with POP3?
by Zhou, Yan 11 Jan '11

11 Jan '11

Hi there, We are using DoveCot 1.0.7. User will use POP3 or POP. We want to force user to securely send their credential and keep a secure connection between us and them. We can do TLS/SSL on port 995, or STARTTLS on port 110. The problem is that we have no way to enforce STARTTLS on 110, user can connect to DoveCot on port 110, sending user credential without STARTTLS (thus insecure). Reading DoveCot documentation does not sound it supports this. Here is what I got from documentation. Dovecot supports: * IMAP (including TLS/STARTTLS) * IMAP+SSL ("imaps") * POP3 (including TLS/STLS) * POP3+SSL ("pops") My only option to enforce securely sending user credential is to enable port 995 and disable port 110, sound right?

[Dovecot] Multiple Authentication Databases
by Jonathan Tripathy 11 Jan '11

11 Jan '11

Hi Everyone, I wish to run Dovecot on my "Front End" outbound mail relay, and use Dovecot purely for authentication purposes. However, each mysql database for each domain will be on a separate server. Is there a way for dovecot to authenticate against different databases depending on domain name? Thanks

[Dovecot] OS X Server Partition Problems
by Bryan Harrison 11 Jan '11

11 Jan '11

I'm a nube to Dovecot and this list. Please be kind. ;) I'm running Dovecot 1.1.20 and Postfix 2.5.5 on OS X Server 10.6.6. I've moved accounts from another, older cyrus-based server (thank god), and used fetchmail to imap the existing mail to the new server. At some point, I developed a problem with my partition map being semi-ignored. Mail is stored in multiple places, and I'm not sure why or entirely clear how it ended up there. My log is overflowing with entries such as… Jan 10 15:44:57 gilded-bat dovecot[65]: auth(default): od(john_doe_com): unable to find partition for tag=johndoe: using default mail location: /var/spool/imap/dovecot/mail …referring to each of my defined partitions. Here's what I semi-understand. /etc/dovecot/partition_map.conf.default contains: default:/var/spool/imap/dovecot/mail /etc/dovecot/partition_map.conf contains correct entries like default:/Mail JohnDoe:/Groups/JohnDoe/Mail [etc.] dovecotd -n is below. It's configuration with regard to mail store locations look ok to me, but then I'm a virgin. In practice, mail is being stored in three different locations. They're all full of mail directories and are busy. /var/spool/imap/dovecot/mail /Mail /Groups/JohnDoe/Mail …with of course the third entry being many entries for each client. The directories described definitely exist. Clients started out being able to see old mail that was transferred from the retired server, but no longer do. I'm not actually clear which of the three mail stores in use are being accessed by whom or for what. (And let's not even ask why none of this showed up in testing.) In short, I'm over my head and the villagers are outside with the usual pitchforks and torches. Thanks, Bryan dovecotd -n # 1.1.20apple0.5: /private/etc/dovecot/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 356).

[Dovecot] dsync not copying all mail
by Nick Rosier 10 Jan '11

10 Jan '11

Hi, I'm still trying to migrate from Dovecot 1.2.16 to 2.0.7 on FreeBSD. Previous attempts have failed with mails not being visible after the upgrade. Version 1.2.16 was migrated from maildir to dbox about a year ago via the convert-plugin. After previous attempts to "clean" the hybrid maildir-dbox situation I used imapsync to copy all mails from the old account to a new account. I would assume in this case I get a clean dbox-mailmap. I tried to run dsync on this new map but noticed a lot of mails are not syncing: [vmail@mail ~]$ find /vmail2/new/bunbun.be/nick | wc -l 5329 [vmail@mail ~]$ find /vmail2/old/bunbun.be/nick | wc -l 6134 Any ideas? N.

[Dovecot] Last login
by Egbert Jan van den Bussche 10 Jan '11

10 Jan '11

Hi, I'm trying to find a way to find inactive users. Is there a simple way to deduct the last login date of a user from that users Maildir files? Are the timestamps on the index files reliable? I ask because the system and dovecot logs are not available to me but I can search the whole .../vmail/domain/user/Maildir tree. I'n running 1.2.9 on ububtu 10.04 LTS with posttfix and postfixadmin. The users (all are virtual) reside in the postfixadmin MySQL tables. TNX Egbert Jan (NL)

[Dovecot] Urgent problem: Dovecot fetches the same mails multiple times per POP
by Andi Meier 10 Jan '11

10 Jan '11

I have a problem since a couple of hours: I manage several mboxes on a virtual server using Dovecot (over POP3). Until a few hours ago, it worked well, but since 11:50, the e-mail clients which access Dovecot's mailboxes, receive all e-mails new each time the mailbox is queried. For example: 15:40 fetches 22 new mails 15:41 fetches the same 22 mails again as new 15:42 fetches the same 22 mails again as new etc. Dovecot version is 1.0.15 on Debian Lenny. How can I fix this? How can I diagnose what's wrong? The mailbox files themselves seem ok, no dupe messages. I noticed that in the /var/log/mail.log Dovecot says: ------- START --------- Jan 10 15:27:08 lvps87-230-81-99 dovecot: POP3(office): Disconnected: Logged out top=0/0, retr=23/6273313, del=23/23, size=6272894 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): Effective uid=1002, gid=1002 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox: data=/var/mail:INBOX=/var/mail/office Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox: root=/var/mail, index=/var/mail, inbox=/var/mail/office Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: Expunged message reappeared in mailbox /var/mail/office (UID 3234 < 3261, seq=2, idx_msgs=0) Jan 10 15:40:02 lvps87-230-81-99 dovecot: pop3-login: Login: user=<office>, method=PLAIN, rip=80.122.113.70, lip=87.230.81.99 Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3261 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:02 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3285 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:22 lvps87-230-81-99 dovecot: POP3(office): mbox sync: UID inserted in the middle of mailbox /var/mail/office (3309 > 3234, seq=2, idx_msgs=24) Jan 10 15:40:22 lvps87-230-81-99 dovecot: POP3(office): Disconnected: Logged out top=2/0, retr=24/6274745, del=24/24, size=6274309 ------- END --------- What puzzles me: Each time the retr=XX value is never decreasing. Shouldn't it be 0/xxxxx the next time when the mails are not kept on the server? Apparently Dovecot does not manage to remove the mails form the mbox, although the email client tells it so (=> del=24/24) Is this the problem? How can I check this? I am very thankful for any hints! Cheers, Andi

[Dovecot] size of "m.XXX" in mdbox
by Joan Moreau 10 Jan '11

10 Jan '11

Hi, How to tune the size of each "m.xxx" file in mdbox format , in order to optimize the ratio size/number of files ? (I can see for instance more than 100 000 files in one directory due to very large mailbox size) If such parameter exists, what is the typical value ? Thanks Joan

Or use sendmail binary from something else than Courier. Yes i'm using sendmail from Courier. When i changed sendmail_path to original sednmail binary it's working and vacation is sent, but i can see some errors from sendmail.

[Dovecot] CatchAll virtual user removes spamheaders
by Peter Reinhold 09 Jan '11

09 Jan '11

Hi all, I am having a small problem with a catch-all user I have setup in my Postfix/Dovecot setup. I am not 100% sure this is Dovecot related, but, logic tells me it is. I have a virtual user called @reinhold.dk setup to redirect to my main account, peter(a)reinhold.dk. If I send a spam mail (GTUBE) to peter(a)reinhold.dk, the mail is marked with Amavis x-headers as it should be. If I send the same mail to peterpeter(a)reinhold.dk, I can see in my maillog that the mail is PASSED SPAMMY, just as the first one, but when I check the mail, all amavis x-headers are missing. (Except one, X-Spam-Virus-Scanned:, which just informs me that the mail has passed through the scanner) Does anyone know if this is a Dovecot issue? (It seems so to me), and if so, any hints on how I can change this behaviour? Kind Regards, Peter Reinhold - peter(a)reinhold.dk > http://www.reinhold.dk & http://www.geekhouse.dk < -- QOTD : Mit internet er der ikke noget porn på .. Det er helt vildt nederen. ..

[Dovecot] can not receive external emails
by Daminto Lie 09 Jan '11

09 Jan '11

Hi, I am new to Dovecot. Recently I have got a new server running on Ubuntu Server 10.04 with Postfix, Dovecot (for IMAP) and Squirrelmail. During the test, I was able to send & receive emails internally, and can send emails externally. However, I got a problem when it comes to receiving emails externally. The emails I sent from yahoo never arrived to my local inbox. Anyway, I checked the mail.log and found the following dovecot: auth-worker(default): dovecot-auth: /usr/locallib/liblber-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap_r-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap-r-2.4.so.2" no version information available (required by /usr/lib/libpq.so.5) I was wondering if anyone might be kind to explain the above error messages and how to work around this so that it could send/receive emails coming from external mail server. Thank you in advance

[Dovecot] IMAP Clients can not see 3rd tier nested IMAP directories
by jjs87＠cornell.edu 08 Jan '11

08 Jan '11

I have a very bizarre problem that I hope someone can help me with. I am not sure if this is a Dovecot problem, or IMAP client problem. I recently used Transend's Migrator to move mail from Exchange 2007 to my Dovecot 1.0.7 server. The program seems to have moved the nested IMAP dirs properly as seen below in a directory listing of the maildir dir. The nested dirs have indexes, cur, new dirs as expected. However, when the account is viewed in Windows Thunderbird 3.1.6 or Outlook 2010 the 3rd tier dirs are not seen, nor can they be subscribed to. On a whim, I decided to try Apple Mail 4.3 to view the account and all the IMAP dirs can be seen and accessed as expected. Any idea what is going on? Is this somehow an IMAP client problem (bug) or an issue with Dovecot and these clients? Listing of the Maildir dir: [root Maildir]# ls -al total 92 drwx------ 17 andrew andrew 4096 Dec 6 17:06 . drwx------ 9 andrew andrew 4096 Dec 6 15:58 .. drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox.mail drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues drwx------ 5 andrew andrew 4096 Dec 6 17:02 .mailbox.mail.colleagues.amy drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues.aslan drwx------ 2 andrew andrew 4096 Dec 6 16:31 cur -rw------- 1 andrew andrew 144 Dec 6 16:31 dovecot.index -rw------- 1 andrew andrew 10272 Dec 6 16:31 dovecot.index.cache -rw------- 1 andrew andrew 128 Dec 6 16:31 dovecot.index.log drwx------ 2 andrew andrew 4096 Dec 6 16:31 new drwx------ 5 andrew andrew 4096 Dec 6 16:53 .Sent Items -rw------- 1 andrew andrew 32 Dec 6 17:06 subscriptions drwx------ 2 andrew andrew 4096 Dec 6 16:31 tmp drwx------ 5 andrew andrew 4096 Dec 6 16:32 .Trash PROBLEM: When viewed in Thunderbird 3.1.6 or Outlook 2010: These nested dirs are seen: ..mailbox ....mail These nested dirs are NOT seen or can be subscribed: ......colleagues ........amy ........aslan OBSERVATIONS: When viewed in Apple Mail 4.3, all dirs are seen correctly.

[Dovecot] Migrate dbox 1.2 virtual mail to 2.0
by Nick Rosier 08 Jan '11

08 Jan '11

Hi, I'm trying to migrate from Dovecot 1.2.16 to 2.0.7. Initially the mails were stored in Maildir format but I changed them to dbox using "fast Maildir migration" and some mails are still in the old maildir format. I'm trying to migrate these mails using dsync but dsync panics: % dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror dbox:/var/spool/vmail2/bunbun.be/nick ...... dsync(vmail): Panic: file mail-storage.c: line 1351 (mailbox_save_set_guid): assertion failed: (guid == NULL || *guid != '\0') zsh: abort (core dumped) dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror Any ideas?

[Dovecot] Pointers for developing a proper encryption plugin?
by dovecot＠moorooboorai.com 07 Jan '11

07 Jan '11

Hi all, One thing that's always itching when I think about mail-servers, is the storage of e-mail messages in (rather) plain-text. Meaning, any administrator with sufficient privileges would be able to read messages not meant for them. Of course, PGP alike solutions exist, but that's not for the masses. In my opinion I would like to have e-mail messages stored encrypted using a (strong) user-supplied password. That password would ideally be the same as the one the user logs in with. So for me it's okay to place and enforce that requirement on any of the users. Having this in place would for sure reassure external auditors/accountants of any kind. Having Google'd from here to 'yonder and consulting experts on Experts Exhange, I have come up with only this pointer: http://dovecot.markmail.org/search/?q=dovecot+encrypt#query:dovecot%20encry… It mention the same issue, and also mentions the non-existence of a solution (back in May 2010). But, beforing diving into developing solutions myself, I have to be absolutely sure that there isn't any solution yet. And, in consequence of non-existence: what would allow me to fasttrack any development efforts on this? Is there an overview available where I could learn the best approach for plugin development? Tutorials maybe? Kind regards, Jeroen Zuijderhoudt.

Hi, Sorry. This is what I find when I try to run Dovecot. # dovecot -F Segmentation fault If I comment out the SSL configuration values, then: # dovecot -F doveconf: Fatal: Error in configuration file /opt/etc/dovecot/dovecot.conf: ssl enabled, but ssl_cert not set These are the configure options, "--enable-maintainer-mode" & "--enable-devel-checks" were added with the hope that dovecot would produce a more verbose error message. ./configure --prefix=/opt --with-ssl=openssl --disable-dependency-tracking --enable-maintainer-mode --enable-devel-checks None of the log files have been touched since before this version of Dovecot was installed (logging was initially part of the configuration).

[Dovecot] dovecot can't see mail that is there
by Joachim Ferreira 07 Jan '11

07 Jan '11

I used to install dovecot on any Fedora fresh installation and I could fetch my internal mail few minutes later. Now I've been struggling for two days and I haven't got my mail working yet. I have Fedora 14 with sendmail. Some application on the same machine send mail to an account on the same machine (hence all is confined to one machine) and I want to retrieve it from a laptop on the same LAN via Outlook. If I login into the account and check the mail with the alpine (ex pine) client, I see that there are 10 mails. When I "telnet localhost pop3" and login into the account, the "list" command says there are 0 mails. Various suggestions found on the internet for slightly different configuration did not help. All the help will be very much appreciated.

[Dovecot] dsync backup errors with maildir -> mdbox
by Patrick McLean 06 Jan '11

06 Jan '11

Hi, In preparation for a migration from maildir to mdbox, I am using dsync backup to do initial mailbox copies (at this point I do not want to risk any changes to the maildir). The initial run of dsync runs fine, but a second run to migrate any changes since the first run produces errors for many users. Here is an example of the type of error produced: > # dsync -u user backup mdbox:~/mdbox > # dsync -u user backup mdbox:~/mdbox > dsync(user): Error: Can't delete mailbox INBOX: INBOX can't be deleted. > dsync(user): Error: Can't delete mailbox directory XXXXXX.courses: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX.XX1: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXX.XX2: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXXXXXXX: Mailbox has children, delete them first > dsync(user): Error: Can't delete mailbox directory XXX: Mailbox has children, delete them first > dsync(user): Error: Trying to open a non-listed mailbox with guid=c0204a140fdd254d1a770000743562c1 > dsync(user): Error: msg iteration failed: Couldn't open mailbox c0204a140fdd254d1a770000743562c1 > dsync(user): Error: Trying to open a non-listed mailbox with guid=c0204a140fdd254d1a770000743562c1

[Dovecot] Alternative storage vs. Self healing (losing flags?)
by Marczisovszky Daniel 06 Jan '11

06 Jan '11

Hi, We are going to set up an environment for our customers where the storage is provided by two servers. First one stores the new emails, second one stores all the others using Dovecot's alternative storage feature (mailbox format is mdbox). The servers are connected via NFS. If, for any reason, the alternative storage is not mounted, Dovecot will see only an empty folder and due to its self-healing functionality flags for messages stored on alternative storage will be lost. Is there any way to prevent regenerating indexes (and especially flags as a side-effect) if the alternative storage seems to be completely empty? (like a dummy file in the root of the alternative storage and an option to enable/disable this check) Thanks in advance, Daniel Marczisovszky

[Dovecot] Login with firstname.lastname instead of loginname - WORKING
by Ralf Hildebrandt 06 Jan '11

06 Jan '11

3 years ago (!) I aksed about this and finally I implemented it today: >> # NEW >> passdb { >> driver = passwd >> # firstname.lastname@charite.de:password:uid:gid:(gecos):home:(shell):user=realloginname >> args = /usr/local/etc/dovecot.login_via_email >> } >If you're only using it as a passdb, you don't need the uid/gid/home. So >an example field would be: > >firstname.lastname@charite.de:password::::::user=realloginname But now I'm encountering problems with users writing Firstname.Lastname(a)charite.de instead of firstname.lastname(a)charite.de (capitalized first letters) How can I "normalize" the usernames by lowercasing them? The coolest solution would be to strip realms AND force lowercasing of usernames in one pass -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Upgrade from 1.2.16 with sieve/managesieve to 2.0.8 with pigeonhole
by Nick Rosier 06 Jan '11

06 Jan '11

Hi, I would like to upgrade my server from 1.2.16 with sieve and managesieve to 2.0.8 with pigeonhole. Will I get all functionality I was having before? Should this migration be painless or will it require some additional work? I've read the Upgrading guide so I know I need to create an additional user. I've migrated the mails from Maildir to dbox in the past (using the convert plugin); does that mean I'm fully dbox or am I in a maildir-dbox hybrid situation? I've noticed that there are still some maildir-formatted mail (e.g. 1259960330.M322229P62710.mail,W=2195:2,S) in some of the maps. root@mail /usr/local/etc # dovecot -n # 1.2.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-PRERELEASE amd64 zfs protocols: imap imaps managesieve ssl_ca_file: /etc/ssl/cert.pem ssl_cert_file: /etc/ssl/mail.crt ssl_key_file: /etc/ssl/mail.key version_ignore: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login valid_chroot_dirs: /var/spool/vmail mail_max_userip_connections(default): 50 mail_max_userip_connections(imap): 50 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes first_valid_uid: 5000 first_valid_gid: 5000 mail_privileged_group: mail mail_location: dbox:/var/spool/vmail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): acl imap_acl fts fts_squat autocreate mail_plugins(imap): acl imap_acl fts fts_squat autocreate mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(managesieve): dict_db_config: /usr/local/etc/dovecot-db.conf namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)xxx.xxx mail_plugins: sieve acl mail_plugin_dir: /usr/local/lib/dovecot/lda deliver_log_format: msgid=%m: %$ sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login cram-md5 username_format: %Lu passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.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: 384 user: vmail group: vmail plugin: acl: vfile:/usr/local/etc/dovecot/acls:cache_secs=300 acl_shared_dict: file:/var/db/dovecot/shared-mailboxes.db convert_mail: maildir:/var/spool/vmail/%d/%n expire_dict: proxy::expire expire: Trash 365 sieve: /var/spool/vmail/%d/%n/dovecot.sieve sieve_dir: /var/spool/vmail/%d/%n/sieve sieve_global_dir: /usr/local/etc/dovecot/sieve fts: squat fts_squat: partial=4 full=10 autocreate: Trash autocreate2: Drafts autocreate3: Spam autocreate4: Sent autosubscribe: Trash autosubscribe2: Drafts autosubscribe3: Spam autosubscribe4: Sent dict: expire: db:/var/db/dovecot/expire.db

[Dovecot] RFC: grouped (f)sync
by Attila Nagy 06 Jan '11

06 Jan '11

Hello, Currently Dovecot (and any other application, which cares about e-mail delivery) does at least one fsync per mail delivery. Given that hard disk drives have a very limited IOPS, this effectively limits the maximum mail delivery performance to a very low value, under utilizing the available storage IO capacity. Calculating with an average mail size of 50 kB and an average consumer HDD with 120 IOPS, the theoretical mail delivery performance will be 50 kB*120 IOPS=5.85 MBps. But if we could write 500 kB with every transaction, the delivery speed would be nearly 10 times as well. Dovecot have two process models: separate processes for each client connection and an async in-process multiplexing method. This works for each one, albeit the timing is somewhat different. So here's the idea: instead of fsyncing immediately in the LDA (lmtpd) every time when the client says "\r\n.\r\n" after the DATA phase, let's introduce a user settable timer (let's call that sync_delay from now on) and only sync in every sync_delay seconds. This would introduce an up to sync_delay seconds delay in lmtpd returning "250 Ok" to the client, but that's generally not a problem, because in high traffic setups there is a great amount of concurrency, so you could use a lot of client connections easily. Take an example setting of sync_delay = 100 ms. With this, 10 syncs would happen in every second from Dovecot LDA processes, meaning if a client connects in t=0 it will immediately got the response 250, if a client connects in t=0.05, it will get the response in 50 ms (in an ideal world, where syncing does not take time), and the committed blocks could accumulate for a maximum of 100 ms. In a busy system (where this setting would make sense), it means it would be possible to write more data with less IOPS needed. I can see two problems: 1. there is no call for committing a lot of file descriptors in one transaction, so instead of fsync() for each of the modified FDs, a sync() would be needed. sync() writes all buffers to stable storage, which is bad if you have a mixed workload, where there are a lot of non-fsynced data, or other heavy fsync users. But modern file systems, like ZFS will write those back too, so there an fsync(fd) is -AFAIK- mostly equivalent with a sync(pool on which fd is). sync() of course is system wide, so if you have other file systems, those will be synced as well. (this setting isn't for everybody) 2. in a multiprocess environment this would need coordination, so instead of doing fsyncs in distinct processes, there would be one process needed, which does the sync and returns OK for the others, so they can notify the client about the commit to the stable storage. Any opinions on this?

[Dovecot] virtual user problems
by G.Nau 06 Jan '11

06 Jan '11

dovecot 2.0.8 with postfix; transfer postfix -> dovecot by lmtp is fine Now i have to redirect a couple of virtual email names (like admin(a)mydomain.com, postmaster@, webmaster@, info@, sales@ ...) to a single user postbox named xxx@mydomain. As I use mysql for the auth-sql, it's returning userhome /home/<name>/maildir for all sql requests to <name>=admin, postmaster etc. I also verified that "doveadm user info" is returning the maildir/home: /home/xxx/maildir So I assumed, that all mails to admin, postmaster etc. are transfered to user xxx mailbox. But it isn't. Dovecot is creating the maildirs /home/admin/maildir, /home/info/maildir and so on. What do I miss here to get that virtual users mapped to the correct user xxx? Regards Birte

[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 ?

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 ?

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.)

[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
by Kyle Wheeler 04 Jan '11

04 Jan '11

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] 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 }

[Dovecot] Courier-mta with Dovecot LDA again
by komodo 04 Jan '11

04 Jan '11

Hi all Sorry for repost, but i don't believe that there is noone who know where the problem can be. At least developers should know :-) I have sent this post once, but without answer. I have setup dovecot lda instead of maildrop on my courier server. Delivery is working, sieve plugin too, but i can't figure out why lda can't send emails via sendmail (vacation). I always get error Error: Sendmail process terminated abnormally, exit status 67 And i know why, but i don't know how to setup lda to make it work . Here is .courier file where is redirect to lda. | /usr/libexec/dovecot/deliver -a $RECIPIENT -f $SENDER But the deliver does not pass recipient address to sendmail. Here is some output of strace execve("/usr/libexec/dovecot/deliver", ["/usr/libexec/dovecot/deliver", "-a", "komodo@somedomain", "-f", "someuser@somedomain"], [/* 22 vars */]) = 0 So it's clear that deliver have those variables, but then i can see this execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "-i", "-f", "<>", "--", "someuser@somedomain"], [/* 2 vars */] <unfinished ...> And there is empty -f , so here is the problem. How should i setup this to make it work correctly ?

[Dovecot] Quota ignore subfolders
by Héctor Moreno Blanco 04 Jan '11

04 Jan '11

Hello, We have dovecot 2.0.8 in our servers with Scientific Linux SL release 5.2 (Boron). We want to ignore a mailbox and its child mailboxes. A few weeks ago Timo told me to do this in dovecot.conf, create a new namespace which will be the quotaless namespace and edit the quota: namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:%h/Maildir/carpeta1 prefix = carpeta1. separator = . type = private } plugin { quota = maildir:carpeta1:ns=INBOX. quota_warning = storage=75%% /usr/local/dovecot/bin/quota-warning.sh 75 quota_warning2 = storage=90%% /usr/local/dovecot/bin/quota-warning.sh 90 } We also have passdb and userdb with ldap, with dovecot-ldap.conf: pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountActive=TRUE)) pass_attrs = uid=user,userPassword=password, mailQuotaSize=quota_rule=*:bytes=%$ user_attrs = mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ user_filter = (&(objectClass=qmailUser)(|(mailAlternateAddress=%u)(mail=%u)(uid=%u))(accountActive=TRUE)) We also tried the easy solution which was to indicate a quota rule in order to ignore the mailbox but with no success. It still get every mailbox to calculate the quota. We set mail_debug=yes to see if there was any error, but everything seemed to be ok. Any suggestions? Thank you very much in advanced.

[Dovecot] Renaming IMAP folders does not affect children
by Johannes Simon 04 Jan '11

04 Jan '11

Hi, we're using dovecot2.0 since August and very happy with it. Just recently Thunderbird users reported problems when renaming folders, and it seems that RFC 2060 (sec. 6.3.5) requires children of a renamed folder to be renamed, too. This however does not happen: Talking IMAP I get: * LIST (\HasChildren) "." "INBOX.NNN1" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" . rename "INBOX.NNN1" "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" * LIST (\HasNoChildren) "." "INBOX.NNN2" There seems to be no problem the filesystem rights, since this works: . rename "INBOX.NNN1.NNN1a" "INBOX.NNN2.NNN1a" * LIST (\HasChildren) "." "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN2.NNN1a" Am I misunderstanding RFC 2060, or is my config wrong (doveconf -n below), or could it be a bug? Cheers, Johannes # 2.0.8 (e030df616faf): /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 x86_64 Debian 5.0.7 default_client_limit = 2500 default_process_limit = 600 dotlock_use_excl = yes log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Dovecot 2 ready. mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = autocreate acl 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 mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { list = yes location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } passdb { args = session=yes dovecot driver = pam } plugin { acl = vfile acl_shared_dict = file:/etc/dovecot/dict/shared-mailboxes autocreate = INBOX.Trash autocreate2 = INBOX.Junk autocreate3 = INBOX.Sent autocreate4 = INBOX.Junk_old autocreate5 = INBOX.Drafts autosubscribe = INBOX.Trash autosubscribe2 = INBOX.Junk autosubscribe3 = INBOX.Sent autosubscribe4 = INBOX.Drafts sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 service auth { unix_listener auth-userdb { mode = 0666 } } service dict { user = dovecot } service imap-postlogin { executable = script-login rawlog /etc/dovecot/postlogin.sh user = root } service imap { executable = imap imap-postlogin } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = blocking=yes driver = passwd } protocol imap { mail_max_userip_connections = 50 mail_plugins = autocreate acl imap_acl } protocol pop3 { mail_max_userip_connections = 3 }

[Dovecot] user xxx@mydomain.com doesn't exist
by G.Nau 04 Jan '11

04 Jan '11

new setup of Dovecot 2.0.8 with postfix local users are simply defined as Linux users named xxx, yyy et cetera; IMAP access is fine with that users. Postfix is delivering mails with two domains (to xxx(a)mydomain.com or xxx(a)mydomain.org) and these are rejected by dovecot with 550: user doesn't exist. I've tested the possible usernames with "doveadm user" xxx: okay xxx(a)mydoman.com: "userdb lookup: user xxx(a)mydomain.com doesn't exist" xxx(a)mydoman.org: "userdb lookup: user xxx(a)mydomain.org doesn't exist" Dovecot2 wiki says "Dovecot doesn't care much about domains in usernames" Okay, how to I get dovecot to ignore the domain part (or accept the two defined domains) when mails are delivered from postfix? Or do I have to configure Postfix to strip the domain part before delivering to dovecot? Regards Birte Nauer

[Dovecot] archiving
by PA 03 Jan '11

03 Jan '11

Hi, recently I installed the newest 2.x version of dovecot working with postfixadmin/mysql and it works great, thanks Timo, however I been reading dovecot's mailing list archived messages and haven't run across a good solution for archiving mail with dovecot. There was mention of using rsync but I was looking for incoming mail to be copied to another folder, maybe called archive J, in real time where the user would have only read access to the messages in the archive folder and the expire plug-in would delete messages older then x number of days. Does anyone have an suggestions on how I can implement this, I would also like to hear how some people were implement archiving if they do it differently. Also as far as shared calendars with dovecot what are my options. Sorry if it's a little off topic. Thanks, Paul

[Dovecot] dovecot director terminate ssl ?
by Jan-Frode Myklebust 03 Jan '11

03 Jan '11

I plan on putting two dovecot directors in front of our backend dovecot pop/imap servers, instead of our current haproxy loadbalancing of the connections -- but how do we handle SSL in such a setup. Will all SSL be terminated on the directors automatically, and then proxyed plain text, or is there any configuration needed to achieve this ? Does it matter that the directors are v2.0 while the backends are running v1.2 ? -jf

[Dovecot] Dovecot Quota plugin as Couier quota
by Antonio Perez-Aranda 03 Jan '11

03 Jan '11

I get a similar behavior between dovecot quota plugin and courier quota with the attached patch. When the client change flags, then is forced to recalc. This is because I don't know how to get the changed flags on quota sync method. The courier quota behavior is avoid to count all deleted mails, include "mark as deleted" mails. -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

new Dovecot 2.0.8 installation on Opensuse 11.3 I got the error "lmtp (xxx(a)mydomain.yy) Error: user xxx(a)mydomain.yy: Initialization failed: Namespace '': mbox: mbox requires client_limit=1 for service" while trying to transfer mails by lmtp from postfix to dovecot. I googled and looked on the dovecot wiki about this client_limit issue, but no success. What's the syntax of the client_limit and where to place it? Into which config file? Inside the global namespace doesn't seems to work (error on dovecot start). -What's the side effect of this setting to my IMAP clients? Are multiple imap connections to the same mailbox still possible? Regards Birte Nauer

[Dovecot] listescape breaks acl plugin
by Jens 02 Jan '11

02 Jan '11

Hi all Without the listescape plugin I see the following things happen: - If I share a mailbox, dovecot-acl-list in Maildir root is updated accordingly. - If I create a subfolder in an already shared mailbox the dovecot-acl file of the parent folder is copied to the new folder and dovecot-acl-list is updated as well. When I activate the "listescape" plugin, this doesn´t happen. Additionally (with listescape enabled), if I create a folder which contains a dot and then share that folder the dovecot-acl-list looses all entries except the first found shared folder without a dot in foldername. I Hope this is not a bug but only a configuration issue. Thanks for any hints in advance and best Regards Jens

[Dovecot] Shared Folders via Symlinking
by Adrian Mardlin 01 Jan '11

01 Jan '11

Hi folks, I'm trying to set up shared folders via symlinking and have come across a problem. I created a folder for one user, then symlinked it to another. I figured that one thing that is likely to happen at some point is that user 2 is going to decide they don't want to look at that folder any more, and will delete it, so I tried this. Much to my relief, it didn't delete the actual mails, just the symlink. However, it did alter the dovecot.index.cache file to indicate that the folder had been removed, and subsequent attempts to select this folder via the primary user resulted in an error, "NO Mailbox was deleted under us". I had to delete dovecot.index.cache to get it working again. Sorry - can't bring myself to call folders mailboxes... ;-) Adrian Mardlin in charge @ The Very Good Email Company t 01442 892641 m 07920 102401 f 01442 808081 w www.verygoodemail.com The content of this email and any attachment is private and may be legally privileged.

[Dovecot] Sieve rule issue with certain character sets

[Dovecot] Dovecot 1.2.12 + Postfix + virtual domains: delivering to system users
by Ran Talbott 01 Jan '11

01 Jan '11

As mentioned in my previous posting, I've set up a mailserver for a domain of Winboxen, authenticated through Active Directory. After some struggles, I finally got that working. But I also need to receive emails for a few system users on the mailserver (like postmaster, and a couple of accounts set up for maintaining the system). I thought, based on the way I read the documentation, that I could just add a "userdb passwd", ahead of the "userdb ldap", and deliver would find their home directory maildirs. The virtual users would fail the passwd search, fall through to the LDAP check, and deliver would drop their mail into their maildirs in the /var/mailstore tree. I knew the system users wouldn't be able to login to the IMAP server, but this isn't a concern. Instead, the system users' mail got bounced, after an auth check via the "master" socket (from Postfix, I guess: it's a transient process) whose details don't get logged. And the virtual users' lookups (done by deliver) returned made-up UIDs and GIDs, and maildir locations (/home/<realm>/<username>) completely different from what the LDAP lookup normally returns (/var/mailstore/<username>). So what am I missing here? I managed to work around this by adding the system users to the Postfix virtual.db, but it would be nice to not need to do that. It would also be nice to neable the system users to check email by logging in to the IMAP serve, but I'm reluctant to even try that after the way delivery went completely wonky. Thanks, Ran

[Dovecot] Can doveadm rebuild thread indexes?
by David Warden 30 Dec '10

30 Dec '10

I'm already using "doveadm search" to update my squat fts indexes (dovecot.index.search and dovecot.index.search.uids) but I'd like to also update dovecot's thread index file (dovecot.index.thread) using doveadm. I checked the new wiki and the archives but didn't see any option for this. (I'm running 2.0.8) The alternative (AFAIK) is to write a script that signs in to IMAP and does "thread references UTF-8 ALL" in each folder. As an aside, could the dovecot LDA do any of this work? I'd surely be willing to spend the resources at delivery time to keep those indexes updated if it meant I didn't have to run a cron job to keep them updated. -David Warden

[Dovecot] LDAP binds
by Trever L. Adams 30 Dec '10

30 Dec '10

I am using 2.0.8. Anonymous binds are no longer supported in the environment I am using. I need to change my userdb ldap setup to bind. I believe the ldap server does Kerberos (or can) authentication. My users are authenticating using Kerberos or Kerberos/PAM. This needs to stay in place. Can anyone suggest how I might go about changing my setup to work? My current ldap setup is as follows (the directories, user id, etc are set statically in the configuration elsewhere): tls = yes hosts = MAILSERVER base = dc=middleearth,dc=sapphiresunday,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) Thank you, Trever Adams -- "Seize the day, put no trust in the morrow!" -- Quintus Horatius Flaccus (Horace)

[Dovecot] IMAP messages not being marked read
by void372＠transientvoid.com 30 Dec '10

30 Dec '10

I recently moved from Fedora 13 to Fedora 14 and consequently to dovecot 2.0.8. Since then, I have observed that messages are not being marked as read in all cases. The general behavior is: 1. Use my mail client to read all unseen messages. All mail folders show no messages unread. 2. Tell mail client to check for new mail. 3. Mail client now says that some folders have new mail (1 or more messages) 4. Clicking on a folder with new mail (say with 6 unread) shows that there are no unread messages. I have observed this behavior using both kmail and squirrelmail so do not believe it is a mail client problem. I have maildir folders to which mail is delivered using procmail recipes directly to the appropriate dovecot folder. In these folders, I notice that the "cur" directory has a matching number of messages that do not have an "S" flag on the end of the file name. For example: # ls .fedora-list/ cur/ dovecot.index.log new/ dovecot.index.cache dovecot-uidlist tmp/ # ls .fedora-list/cur 1293379204.26554_1.nehalem.home.rainbowdreams.com:2,S 1293379206.26571_1.nehalem.home.rainbowdreams.com:2, 1293379207.26581_1.nehalem.home.rainbowdreams.com:2, 1293380106.26744_1.nehalem.home.rainbowdreams.com:2, 1293380106.26748_1.nehalem.home.rainbowdreams.com:2,S 1293381904.26876_1.nehalem.home.rainbowdreams.com:2,S 1293383704.26978_1.nehalem.home.rainbowdreams.com:2,S 1293384604.27005_1.nehalem.home.rainbowdreams.com:2,S 1293385504.27067_1.nehalem.home.rainbowdreams.com:2,S 1293386404.27105_1.nehalem.home.rainbowdreams.com:2,S 1293387305.27158_1.nehalem.home.rainbowdreams.com:2, 1293387305.27166_1.nehalem.home.rainbowdreams.com:2, 1293388204.27193_1.nehalem.home.rainbowdreams.com:2, 1293389105.27234_1.nehalem.home.rainbowdreams.com:2,S 1293390005.27292_1.nehalem.home.rainbowdreams.com:2,S 1293390006.27298_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27400_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27406_1.nehalem.home.rainbowdreams.com:2,S 1293393611.27515_1.nehalem.home.rainbowdreams.com:2,S 1293396304.27673_1.nehalem.home.rainbowdreams.com:2,S 1293396305.27675_1.nehalem.home.rainbowdreams.com:2,S 1293398104.27743_1.nehalem.home.rainbowdreams.com:2,S 1293399003.27966_1.nehalem.home.rainbowdreams.com:2,S I have so far been unable to observe a pattern as to which messages get affected. I made the assumption that perhaps the issue is a conversion issue in my existing maildir folders, but this does not appear to be the case. When I moved the existing directory out of the way and started with a fresh empty directory the issue has come back after a day or two. Unfortunately, my install of Fedora 14 overlaid the partition with Fedora 13, so I cannot confirm the version of dovecot I was using with no issues. (so very glad I use separate disk and partition for the OS!) I can say that all configuration was in one dovecot.conf file, not the multiple conf.d files I see on Fedora 14. Any assistance on what to troubleshoot next is greatly appreciated! The info about my dovecot is shown below. The maildir's are on local LVM/RAID and not remote.

[Dovecot] Dovecot consulting companies
by Timo Sirainen 30 Dec '10

30 Dec '10

Once in a while someone asks about companies who could help installing / running / etc. their mail server. I don't really know many, so I thought I'd add a wiki page about it. Feel free to add your company on the list if you offer some Dovecot related services. Write also a few words what type of services you offer. http://wiki2.dovecot.org/Consulting I'll add a link there once at least one company is listed. :) Oh and if it's not clear above, I don't mean that the list should contain companies that only offer email accounts (Dovecot or not).

[Dovecot] Reverting from 2.0. to 1.2
by Thomas Hummel 30 Dec '10

30 Dec '10

Hello Timo, I switched this morning from dovecot-1.2.12 to 2.0.8 with a basic setup (high performance login mode, Maildir, everyhing on NFS, one shared but unused namespace). No problem so far except that some Thunderbird users who wouldn't succeed in moving messages from some one folder to another. They'd get a message about some illegal character in the mailboxname (already existing mailbox of course). This is user input so I don't have any details nor sufficient element to consider it a real problem. A Thunderbird restart seems to solve the problem. My questions were : . is there a different handling in the hierarchy separator (internal or advertized for the namespace) ? (I use "/" for both namespaces and "." since in Maildir). . is there a different handling in the non-ASCII mailbox names ? Could it be related ? . if something goes really wrong, is it safe to revert to 1.2.12 ? Maybe some files has non-compatible format (dovecot-uidlist, indexes, ...) ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] over quota issue
by PA 30 Dec '10

I have a situation where if a user is over quota and sending through postfix I get an error, now this error only happens if the user is over quota, otherwise it works with no problem. However if sending using /usr/local/libexec/dovecot/dovecot-lda it works every time even if overquota, any ideas? I just can't seem to figure this one out.

[Dovecot] Dovecot 1.2.12+Postfix+Active Directory: virtual domain name dropped.
by Ran Talbott 30 Dec '10

30 Dec '10

I have a Windoze-only client who wants to move their mail hosting from godaddy.com hosting to an in-house system. I'm pitching Linux as an alternative to Exchange, and trying to set up a demonstration system for them. While a long-time Linux user, my server admin experience has been in setting up front-ends (mostly Apache-based web interfaces) for the embedded systems I specialize in. The goal is to have an IMAP server where the users don't have Linux IDs, and only need to manually login to the Active Directory domain controller. The client has multiple Internet domains, but all users are in the same Active Directory realm internally. With the help of the how-tos at linuxmail.info, I got the system to the point of being able to authenticate logins for both IMAP and SMTP (usng dovecot-SASL). I tried using PAM first, but it didn't work: running kinit from the command line takes over 90 seconds to get a ticket, and Dovecot timed out after 60 on every login attempt. So I switched to LDAP. Note: I still don't understand why, but authentication through Active Directory didn't work until I changed the querying distinguished name from the "cn=,dc=,dc=" format to "user(a)xxxx.local" format. I have Postfix using dovecot-deliver as the LDA, but I hit a snag: deliver is not putting the domain name in the path to the maildir. I have the active directory query set as: user_filter = (&(objectClass=user)(samaccountname=%n)) user_attrs = =home=/var/mailstore/%d/%n. =uid=501, =gid=501, \ =mail=maildir:/var/mailstore/%d/%n/Maildir/ When I send mail to testing.testing(a)xxxx.xxx (real domain obscured), I see this in mail.log Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master in: USER#0111#011testing.testing(a)xxxx.xxx#011service=deliver Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): user search: base=dc=lawley, dc=local scope=subtree filter=(&(objectClass=user) (samaccountname=testing.testing)) fields= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): result: objectClass(?unknown?)= cn(?unknown?)= sn(?unknown?)= givenName(?unknown?)= distinguishedName(?unknown?)= instanceType(?unknown?)= whenCreated(?unknown?)= whenChanged(?unknown?)= displayName(?unknown?)= uSNCreated(?unknown?)= uSNChanged(?unknown?)= name(?unknown?)= objectGUID(?unknown?)= userAccountControl(?unknown?)= primaryGroupID(?unknown?)= objectSid(?unknown?)= sAMAccountName(?unknown?)= sAMAccountType(?unknown?)= userPrincipalName(?unknown?)= objectCategory(?unknown?)= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master out: USER#0111#011testing.testing#011home=/var/mailstore//testing.testing. =uid=501#011gid=501#011mail=maildir:/var/mailstore//testing.testing/Maildir/ i.e., the domain does not appear in the paths to the home directory or maildir. I found a bug report in the mailing list that looks like it might be the same problem (%d not supported in user_attrs), but the fix it references is for 2.0. Is this a known problem in 1.x? Is there a fix/workaround for it? E.g., could I have Postfix generate the maidir path and pass it to deliver as the "-m" parameter? Thanks, Ran

[Dovecot] Is this really a user agent issue?
by Phil Howard 30 Dec '10

30 Dec '10

I suspect this is a user agent issue, given that Evolution is flaky in so many areas. When I deliver mail to a subfolder/subbox (e.g. the -m option in the deliver command), and Evolution doesn't know of it, yet, creating it fails, and Evolution still can't get to it. Doing things the other way around (create it in Evolution first, then deliver to it) works fine. Seems to be silliness to me. Just wondered if any Dovecot aspects might be involved ... such as the fact that the case is different (e.g. "INBOX" in the filesystem, but "Inbox" in Evolution). -- sHiFt HaPpEnS!

Hi, I installed openSUSE 11.3 server version, and followed the guidelines from: http://www.howtoforge.com/perfect-server-opensuse-11.3-x86_64-ispconfig-3 Everything works, accept loggin into dovecot. For many days i tried to get logged into dovecot, from localhost, from other pc in the lan, from squirrelmail, not possible. I read manuals on http://wiki.dovecot.org/ and tried to set the passwd db like: auth default { .. passdb passwd-file { args = /etc/passwd.dovecot } .. The "args" were not accepted according to the output from dovecot -n As now i installed dovecot 20, with a fresh dovecot.conf. Ofcourse this was not working, so i 'updated' ISPConfig. Now my dovecot.conf is a mess, and i get errormessages like: Dec 20 21:00:02 AsusTT-sfn6 postfix/smtpd[7073]: fatal: no SASL authentication mechanisms And from dovecot: dovecot.pem missing from /etc/ssl/certs, so no ssl login possible also Now i am checking dovecot -n line by line and this message pops out: mail_plugin_dir: access(/usr/lib/dovecot/modules/imap) failed: No such file or directory passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } furtheron: ssl = no userdb { driver = passwd } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } it has 64 lines. first and last_valid_uid and gid are set to 5000. In this conf i did not change anything. I would realy appreciate some help, as my only goal was to set up an imap server so i can access my mail from all over the world, and have all mail in 'one' central place, instead of scattered all over many pc's and laptops. The irony is that evrything but this works ;-p tia, for an answer.

[Dovecot] director in large(ish) environments
by Cor Bosman 28 Dec '10

28 Dec '10

Hey all, just wondering who here is running the director service in a larger environment. I just switched our whole production setup to the director and am quite pleased with the result. We're doing a peak of about 25000 tot 30000 concurrent sessions on 3 servers. But ive shut 1 server down a couple of days ago to see what would happen and 2 servers carried the load easily. (16 CPU, 24GB memory servers). If others are using the director on larger setups maybe we can all post when things do or dont work well. Now to see if the solution is better than the problem :) Cor

[Dovecot] Migrate from Maildir to mdbox
by Odhiambo Washington 28 Dec '10

28 Dec '10

Looking at http://wiki2.dovecot.org/Migration/MailFormat, I do not see much on how to do a migration from Maildir to mdbox. That page isn't quite updated it looks. I have several domains (virtual) with the following storage layout: /var/spool/virtual/$domain. So the users have their mail stored as follows: /var/spool/virtual/domain1/$user/Maildir /var/spool/virtual/domain2/$user/Maildir /var/spool/virtual/domain3/$user/Maildir /var/spool/virtual/domainN/$user/Maildir >From the wiki, I am told the steps to take are: 1. Set mail_location=mdbox:~/mdbox 2. Run "doveadm mirror -u username maildir:~/Maildir" The instruction above confuses me because in my situation, I don't have a "username" per se. dovecot-deliver knows how to figure out my usernames and their mail_location settings. How do I derive my "username" when users are virtual, stored in MySQL back end? Again, the right command seems to rely on dsync, not "doveadm mirror". I could manually get all the values for the users for each domain and run: dysnc -u $u -o "mail_location=maildir:/var/spool/virtual/domain1/$u/Maildir" mirror "mdbox:/var/spool/virtual/domain1/$u/mdbox" This is so manual, especially because I have to (if I remember well) create /var/spool/virtual/domain1/$u/mdbox (and have the permissions right) before running dysnc. Is there an easier way out, perhaps?? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] Kicking by dovecot as proxy?

[Dovecot] Status update

Just in case you're wondering: I should hopefully soon get back to answering all the pending mails and start coding. I moved back to Finland a week ago. I should get my proper internet connection on Wednesday, although this 3.5G isn't too bad either. I couldn't get my old Mac Mini to work properly anymore so I went and bought a new machine. Dovecot recompiles in 43 seconds now. :)

[Dovecot] passwd, gid and uid
by Mauricio Tavares 25 Dec '10

25 Dec '10

I forgot the answer for this: in http://wiki.dovecot.org/AuthDatabase/PasswdFile, we have the passwd file defined as user:password:uid:gid:(gecos):home:(shell):extra_fields What should the uid and gid be associated with? In my setup I told postfix to use Dovecot LDA's deliver, which then is saving files as uid:gid of 1500:1500. How would that affect the uid:gid used in the passwd file? From what I read in the dovecot's wiki, you want them *not* to be anything that has the rights to access the emails. So, does that mean any value for them will do?

[Dovecot] Maildir feature I'd like to see - SSD for newer messages
by Marc Perkel 24 Dec '10

24 Dec '10

SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it. Some new SSDs use SATA 3 (6gb/sec) with 355/mb/sec read speeds and 215MB/sec write. Put these in raid 0 and it screams! Can you imagine how fast that would be? What would be nice is if new email were on faster drives with old email being migrated to larger mechanical cheaper storage. Perhaps messages over a month old? From dovecot's perspective it would sort of all look the same but maybe one a week a script would run migrating older messages to slower media. It would also make backups easier. The faster newer messages could be archived hourly. On the weekend after the archiving script was run the older message could be backed up once a week. I'm not sure what it would take to make dovecot seamlessly access email from two different locations or if this is practical. Just wanted to throw the idea out there to see if something sticks.

[Dovecot] Is this an index problem?
by Chris Barnes 23 Dec '10

23 Dec '10

This is my first post to this list/gmane newsgroup, so please be gentle with me.... :-) Here's my situation: I have a user (the "main boss secretary") who uses MS Outlook 2007 as her email client. She has over 46,000 messages in her inbox, with nobody knows how many more in 75+ different folders & subfolders. Surprisingly, her response time wasn't too terrible up until we had to reboot our mail server the other day (actually, restoring the entire server from a backup). Now it takes anywhere from 10 to 60 seconds for her to switch from 1 folder to another. Details: * Server is Debian running Postfix and Dovecot (both the current release). Using Maildir format stored in the user's ~/Maildir folder. * User connects to server via Imaps. Connection is local using gigabit network (ie. it ain't the network). * Yes, we did all the things on the Outlook side -thinking that is where the problem lays. Rebuild the .pst file, had Outlook re-index, compacted the .pst file, etc. So now I'm thinking that maybe I need to just wipe out all of the ~/Mailder/dovecot* files (including all those in sub-directories) and let it all reindex. Which begets 3 questions: (1) will this help? (2) anyone have a shell script that will remove all those dovecot* files from the user's directory AND all the sub-directories? (3) Any other suggestions I might be missing? -- Chris Barnes

[Dovecot] Deliver limit based of number of destination recipients and size of mails, any option to do that?
by Andrés Yacopino 23 Dec '10

23 Dec '10

I have a mail server with postfix, dovecot (1.2.15) and deliver lda (dovecot) with 350 users. I have the problem that in this christmas the employees are sending some big files (mainly powerpoints files) to a lot of recipients, because of that the server get a lot of charge (is a Xeon quad core 5405 with 4GB of Ram), i have four disks in Raid 5 configuration (HP E200 controller, not very fast) Is there any option to limit this type of delivery, the total size of the mails delivered to each user (total recipients * size of mail), in dovecot deliver. I don't want to limit the concurrent delivery more lower than 350 recipients and the max size of the mail we can send is 15M. Thanks a lot, -- Andrés Fernando Yacopino

[Dovecot] trying to make cmusieve happen globally
by Phil Howard 22 Dec '10

22 Dec '10

In Dovecot 1.1.11 cmusieve is apparently integrated in the Ubuntu 9.10 package "dovecot-common" since the files are there. I am wanting to right now just do a very basic test of the setup to see how it runs before doing more sophisticated steps that could obscure any errors or bugs (e.g. unit testing). So I took the following example sieve script from the wiki1 documentation: require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "spam"; } and recoded it to skip the test and just always do the fileinto step like so: require "fileinto"; fileinto "spamtest"; Then I configured my dovecot.conf file (via dovecot-postfix.conf it really points to) by setting: protocol lda { ... mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda ... } and: plugin { sieve_global_path = /etc/dovecot/sieve-global.d/spam.sieve } I manually compiled /etc/dovecot/sieve-global.d/spam.sieve so there also exists /etc/dovecot/sieve-global.d/spam.sievec in the same directory. Then I restarted both Dovecot and Postfix. Mail is being delivered, but still only to the same place it always has. The filesystem shows these sieve files are not being accessed at all. I've read documents http://wiki1.dovecot.org/LDA/Sieve and http://wiki1.dovecot.org/LDA/Sieve/CMU to come up with this. But it just doesn't seem to be happening. So I guess it is a good thing I've broken my testing down into smaller units. Anything standout that I misinterpreted about the documentation? If not, I can post the whole config files (in case there is a conflict with something else I have done). FYI, I'm only trying to do a global sieve, not per-user sieve scripts. I'll tackle per-user stuff at a later date, after the global is working. -- sHiFt HaPpEnS!

[Dovecot] Managesieve with multiple uid's

22 Dec '10

Hi, I'm trying to setup a system with dovecot to remove the old courier one, and everything (pop3, imap, lmtp, quotas) but managesieve is working fine. It seems like it's a problem with each user having a separate uid, because I have a working similar setup with a single uid working without problems. In this system when I try to connect to the managesieve port using telnet I get no response: $ telnet localhost 4190 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1).

[Dovecot] Restarting dovecot-auth stops authentication
by Attila Nagy 22 Dec '10

22 Dec '10

Hi, The Dovecot wiki states that Dovecot's master restarts all died processes, which is good for availability. But when I kill dovecot/auth (to simulate an error condition which happened on a machine), the authentication fails with: Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master) failed: No such file or directory It seems -albeit it gets restarted- dovecot/auth doesn't re-create its socket file. Before: # ls /var/run/dovecot/ anvil auth-worker doveadm-server anvil-auth-penalty config dovecot.conf auth-client dict empty auth-login director-admin lmtp auth-master director-userdb login auth-userdb dns-client master.pid # ps auwx | grep dovecot/auth dovecot 87455 0.0 0.0 20024 3832 ?? S 2:34PM 0:00.01 dovecot/auth # rm /var/run/dovecot/auth-master; kill 87455 # ps auwx | grep dovecot/auth dovecot 88815 0.0 0.0 20024 3776 ?? S 2:36PM 0:00.01 dovecot/auth # ls /var/run/dovecot/ anvil config dovecot.conf anvil-auth-penalty dict empty auth-client director-admin lmtp auth-login director-userdb login auth-userdb dns-client master.pid auth-worker doveadm-server I've deleted the auth-master socket because if I don't, you can't see that it's not re-created. :) Is this a normal behaviour? I understand that killing dovecot/auth is not, but Dovecot could survive this easily, if recreating and re-using the new socket file would work. And loosing dovecot/auth happens sometimes (I don't yet now why). Thanks,

[Dovecot] Moving email between folders outside of IMAP context
by Phil Howard 22 Dec '10

22 Dec '10

I'd like to run a script from cron that will scan certain mailboxes and move selected mail from one folder (usually INBOX) to another folder. The basic idea is to move previously detected spam based on headers prepended to the mail. Since I am not able to figure out how to get Postfix to invoke deliver with the -m option in these cases, and not in others, this is one idea I have come up with to deal with it. The big (hopefully obvious) complication seems to be getting the indexes updated. Is there a way to move mail this way AND then have the indexes updated to reflect that move (maybe even if regenerating the entire index all over again)? -- sHiFt HaPpEnS!

Hi there, is it possible in any way to have private seen flags for users in a shared mailbox? http://wiki2.dovecot.org/SharedMailboxes/Shared says no, but i'm not sure, if newer mailbox formats can do this... like mdbox oder something like that. thanks for your help Tobi --

[Dovecot] Maildir and Solaris UFS acls
by Tom Lieuallen 21 Dec '10

21 Dec '10

I have a centrally located shared imap folder location. We have several maildir folders with different file system permissions. They are for several groups of people who are loosely related for support purposes. All mail gets delivered to queue1 just fine. The files are group writable by group1. Some of the mail gets moved via imap to queue2. Queue2's maildir tree is configured with Solaris UFS acls such that any new files are read/write by group1 or group2. If a new file is created within queue2 anywhere, it has the correct permissions. However, if a message is moved from queue1 to queue2, it retains the permissions that it had within queue1. This is what happens if I use 'mv' within the file system, btw. Is there any way to configure dovecot such that if a person moves or copies a message to another imap folder, it creates a new file instead of doing a link or mv or whatever? If not, no problem; I was just hoping for an elegant solution to my particular problem. :-) queue1 - read/write by group1 queue2 - read/write by group1 & group2 through solaris ACLs BTW, if any file whatsoever in queue2 is not readable by group2, those in group2 cannot read _anything_ in queue2. thanks Tom Lieuallen

[Dovecot] Best way to move mail to an archive
by Richard C. Cox 19 Dec '10

19 Dec '10

Hello all...new to dovecot and this list. I have a question that may have been answered before, but I can't find anything yet that addresses it directly. I installed dovecot 2.0.8 (+postfix, fetchmail) on a small server to manage several e-mail accounts. I love this software! So, to back to the question: I'd like to archive e-mail as it ages into a single IMAP archive directory. Ideally, I would like to set up a cron job to search for e-mail in all of my imap directories that older that 'X' days and move it to the archive directory. I know that dovecot wants to manage e-mail movement thru the IMAP interface, so I'm leery of just using ordinary Linux commands to move mail around and bypass the IMAP protocol. Does anybody have any recommendations about dovecot/IMAP safe commands I could use to accomplish this task? Thanks in advance and I apologize for not being more knowledgeable about this subject. Regards, Richard

[Dovecot] Problem with expunge
by Jeff Mitchell 18 Dec '10

18 Dec '10

I'm running Dovecot 2.0.8. The other day I tested doveadm expunge on a test Inbox with a few messages received over the course of a day, and using savedbefore <a few hours>, and it seemed to work. However, today I was testing converting some maildirs over to sdbox, and noticed odd behavior: it's deleting all messages in the specified folder instead of just the ones matching the condition I'm using ("savedbefore 4w"). The command I'm using is "doveadm -Dv expunge -A mailbox Trash savedbefore 4w" Because of the conversion, all of the ctimes for all of the files are actually the same (basically, a few minutes ago), due to the converstion to sdbox from maildir, so I would expect that either it doesn't delete any of them or looks inside at some header of the mail (half of which was received/placed into Trash before 4w ago and half of which wasn't). I definitely don't expect full-on deletion... Any idea what's going on? Thanks, Jeff

Hi, after deciding to use Dovecot 2.0.8 as a postfix LDA using mysql DB I'm running into some issues. I started to follow, http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL but noticed that the auth settings on the config changed, after looking through the dovecot wiki I think I have that issue fixed.

With LIST "Shared/" the other users INBOX is missing, so with namespace capable clients like Thunderbird it is impossible to see or subscribe this folder. The "Public/" namespace has some subfolders, but only for other acl_groups and I don't have rights to access any of them. So the LIST "Public/" looks good. However, with LIST "" * it is shown without the trailing slash and with \HasChildren where it should be hidden. Here is the relevant doveconf -n output: ... namespace { list = children location = maildir:%%h/Maildir:INDEX=~/shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = children location = cydir:/var/spool/imap/public:INDEX=~/public prefix = Public/ separator = / subscriptions = no type = public } ...
