[Dovecot] Upload / migrate old mails: iPhone shows oldest mails first
by Denny Schierz 19 Dec '12

19 Dec '12

hi, I've got a very strange behavior: I uploaded old mails from a local folder (thunderbird / osx) to my Dovecot (Debian Squeeze) and now, the iphone (ios6) show the oldest mails first. The only thing I can imagine is, that Dovecot got from Thunderbird the newest mails first and last the old mails, so that in the last mdbox are the old one. So, if it is correct, how can I fix it? cu denny

Hi! It seem that tview_lookup_seq_range works incorret, if I request uids from 3 to 3, and I have new uids 1,2,4,5 it will return seq for uid=4. Fixing patch is included as attach. ------ Sergey Potapov

[Dovecot] Too many imap connections in state "idling"
by 3.listas＠adminlinux.com.br 19 Dec '12

19 Dec '12

Hi, I have a "Ubuntu12.04 + dovecot-2.0.19" configuration in my server. My mailbox server is shared by ~ 10k domains. It works fine with ~50k accounts. On average, my server has about 6K simultaneous imap connections during office hours. But I've noticed that this server has an average of approximately 4k connections in state "idling". On other Dovecot servers the average connections in state "idling" is only 10%. My doveconf -n: http://thiagoh.prv.digirati.com.br/doveconf-n.txt Can someone help me? Thanks -- Thiago Henrique adminlinux.com.br

[Dovecot] Dsync help, new attempt
by Torbjorn Astlind 19 Dec '12

19 Dec '12

I observe that dsync fills Maildir correctly incl. cur, if I delete Maildir just before dsync runs. Can the failed mbox to Maildir conversion be caused by dovecot creating Maildir automatically if a client connects to dovecot? Should dovecot be shutdown when running dsync? All the best, Torbjörn 9. dsync help?

Message-ID: <50C600B4.4040603(a)dbb.su.se> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi all, I have dovecot serving aprox 200 users through mbox, but the time has come to migrate to a new server, and to use Maildir. Using rsync from the old server I get all user data, i.e /home/*, and inboxes i.e /var/mail/* to a new server. This has worked well for some time as backup. The dsync should convert everything to Maildir, and it does... to an extent. (linebrakes for easy viewing) What I see, is that often, the /home/mail/xxx is NOT resulting in /home/xxx/Maildir/cur All mailboxes from /home/xxx, are properly converted to /home/xxx/Maildir/.name_of_ box Am I misunderstanding something?

[Dovecot] Advice on sieve vacation for aliases
by Marcio Merlone 19 Dec '12

19 Dec '12

Greetings, I have a working mail server with sieve 1:1.2.9-1ubuntu6.5 working just fine. My commercial dept. has asked me to set a vacation message for comercial(a)domain.tld, but this is an alias to jhon(a)domain.tld and meggie(a)domain.tld. I have created a sieve_global_path = /etc/dovecot/global.sieve and it works, but not the intended way: it sends two vacation messages, each From: each employee, and not From: comercial(a)domain.tld alias. Is there how to make dovecot send only one vacation message From: comercial(a)domain.tld or will I have to survive with one message from jhon and another from meggie? Also, is there how to have a dovecot.lda-dupes for the alias instead the users? /etc/dovecot/global.sieve: require ["vacation"]; # rule:[Ferias coletivas] if anyof (header :contains "To" "comercial(a)domain.tld") { vacation :days 7 :subject "Férias coletivas de 20/12/2012 a 07/01/2013" text: bla bla bla. ; stop; } Thanks in advance and nice holidays. -- Marcio Merlone

[Dovecot] Adding a parameter to dovecot's deliver to get a meaningful return value
by Cyril RUSSO 18 Dec '12

18 Dec '12

Hi, First, please forgive me as I'm not subscribed to the list. I'm using Dovecot 2 (2.1.7) for serving my local maildir. This maildir is filled by an external process, fetching & merging mails from different sources that's outside this scope (but it's working). Dovecot is thus acting as a MTA, but more as a MDA. I've a web client running on the server, and it connects to Dovecot to get the mails. I've configured this web client & dovecot to use sieve to filter the mails. I know that since Dovecot does not actually deliver the messages, it's not the expected behavior. Anyway, I can use the "deliver" software in your suite for passing sieve's rules on each message in my maildir, and it's almost working. I've a cron job that run deliver on each message of my maildir, but I'm a bit puzzled now. Basically, I'm not able to figure out if a message was matched by a sieve filter or not. I'm a bit disappointed by two things: 1) Sieve's reject doesn't make "deliver" to return an error, so a sieve rule chain ending in "reject" can't be detected from my cron's script. I wonder it's due to the step deliver is supposed to be run (after a mail is already accepted). 2) "deliver" doesn't have a method to find out if it processed the given mail as input. Basically, would it be possible to either add a parameter to "deliver" (for example: "--fail-on-discarding") so it would fail if the sieve rules discard or reject (/ereject) the mail ? That way, I could detect the failure in my script, and know that I don't need to delete the initial mail since it was not filtered. Or, thought differently, I wonder if "deliver" could open a socket/pipe/file whatever, and write the number of processed mails in there (or using a "--return-processed-mail"), so a sieve rule ending with "delete", would be detectable by my script. Best regards, -- Cyril

[Dovecot] Clear-text ldap passwords: {CLEAR} scheme?
by Kristof Bajnok 18 Dec '12

18 Dec '12

Hi, if I read the documentation correctly, the clear-text password storage scheme in Dovecot is called PLAIN. Unfortunately, in Sun LDAP Directory Server I have to specify them as "{CLEAR}" [1]. Is it somehow possible to make Dovecot recognise "{clear}foobar" passwords as plaintext? Now I get: auth: Error: ldap(username): Unknown scheme clear Thanks, Kristof [1]: http://docs.oracle.com/cd/E19850-01/816-6699-10/confattr.html#passwordStora…

[Dovecot] dovecot-lda (2.1.12) segfaults
by Joseph Tam 18 Dec '12

18 Dec '12

We uograded our dovecot from version 2.1.10 -> 2.10.12, but within the first hour of use, dovecot-lda would segfault during delivery. This left a lock file lying around causing the user's mail readers to hang; much hilarity ensues. All further deliveries to the same user will result in a crash. The only thing that fixes this condition is to blow away the user's INBOX cache index. Reindexing with "doveadm index" does not fix anything. I've installed a test version with one user's problematic INBOX cache indices and ran gdb dovecot-lda (gdb) run -t testuser </dev/null and it crashes with the following backtrace Program received signal SIGSEGV, Segmentation fault. 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 323 if (field_hdr->size < sizeof(*field_hdr) + (gdb) bt #0 0xff2a0440 in mail_cache_header_fields_read (cache=0x5c120) at mail-cache-fields.c:323 #1 0xff29e8bc in mail_cache_compress_locked (cache=0x5c120, trans=0x63ce8, unlock=0xffbfeeef) at mail-cache-compress.c:361 #2 0xff29efd0 in mail_cache_compress (cache=0x5c120, trans=0x63ce8) at mail-cache-compress.c:489 #3 0xff2a3df4 in mail_cache_transaction_compress (ctx=0x5dac0) at mail-cache-transaction.c:180 #4 0xff2a4084 in mail_cache_transaction_open_if_needed (ctx=0x5dac0) at mail-cache-transaction.c:241 #5 0xff2a6e60 in mail_cache_field_want_add (ctx=0x5dac0, seq=1, field_idx=12) at mail-cache-transaction.c:1048 #6 0xff27e8e8 in index_mail_parse_header_register_all_wanted (mail=0x5e6b0) at index-mail-headers.c:175 #7 0xff27ec90 in index_mail_parse_header_init (mail=0x5e6b0, headers=0x0) at index-mail-headers.c:230 #8 0xff27f5c8 in index_mail_cache_parse_init (_mail=0x5e6b0, input=0x63760) at index-mail-headers.c:376 #9 0xff2299cc in mbox_save_get_input_stream (ctx=0x5dde8, input=0x62ed0) at mbox-save.c:411 #10 0xff22a084 in mbox_save_begin (_ctx=0x5dde8, input=0x62ed0) at mbox-save.c:520 #11 0xff24e9c0 in mailbox_save_begin (ctx=0xffbff514, input=0x62ed0) at mail-storage.c:1652 #12 0xff23f138 in mail_storage_try_copy (_ctx=0xffbff514, mail=0x54cd8) at mail-copy.c:68 #13 0xff23f23c in mail_storage_copy (ctx=0x5dde8, mail=0x54cd8) at mail-copy.c:93 #14 0xff24ec28 in mailbox_copy (_ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1721 #15 0xff24ec98 in mailbox_save_using_mail (ctx=0xffbff670, mail=0x54cd8) at mail-storage.c:1730 #16 0xff388070 in mail_deliver_save (ctx=0xffbff8a8, mailbox=0x13fe8 "INBOX", flags=0, keywords=0x0, storage_r=0xffbff83c) at mail-deliver.c:317 #17 0xff38869c in mail_deliver (ctx=0xffbff8a8, storage_r=0xffbff83c) at mail-deliver.c:403 #18 0x00012d08 in main (argc=3, argv=0xffbff964) at main.c:434 I dumped the value of field_hdr, and it has some bogus value (gdb) p field_hdr $1 = (const struct mail_cache_header_fields *) 0x20 Other observations - blowing away the indices does not fix it permanantly.

[Dovecot] NFS, deleting folder issue
by Catalin Petrescu 18 Dec '12

Hi there, I use dovecot on a server with some Nightmare File Systerm (aka NFS) storage. When I delete a folder, its content gets deleted, but the folder itself does not. Here's what I found: #### Step 1: From a shell, telnet to imap, then create a folder cpetrescu@cpetrescu-mobile:~$ telnet server1.localdomain 143 Trying 10.200.28.36... Connected to server1.localdomain.

Here's the content of F1 before calling delete_dir: Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "new" inode: 843617 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "tmp" inode: 843623 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "cur" inode: 843616 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "dovecot.index.log" inode: 2363059 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: "." inode: 843612 Dec 05 10:29:14 imap(testuser1): my_delete_dir: d_name: ".." inode: 807717 And here's its content after calling delete_dir Dec 05 10:29:15 imap(testuser1): my_delete_dir: name: INBOX/F1 Dec 05 10:29:15 imap(testuser1): my_delete_dir: path: /data/testuser1/Maildir/INBOX/F1 Dec 05 10:29:15 imap(testuser1): my_delete_dir: ret: -1 Dec 05 10:29:15 imap(testuser1): my_delete_dir: error: "Directory not empty" trying again Dec 05 10:29:15 imap(testuser1): my_delete_dir: d_name: "." inode: 843612 Dec 05 10:29:15 imap(testuser1): my_delete_dir: d_name: ".." inode: 807717 Dec 05 10:29:15 imap(testuser1): my_delete_dir: d_name: ".nfs0000000000240eb3000000e0" inode: 2363059 Dec 05 10:29:15 imap(testuser1): my_delete_dir: ret: -1 So, the dovecot.index.log was deleted, but it's still open, and the folder can't be deleted because of the pesky .nfs* file. Now, the question: Is there a *magic* function that closes "dovecot.index.log" that I can call before delete_dir()? I tried mailbox_log_close() but it didn't help. Thanks a lot. p.s. Please don't suggest that I should not use NFS! I know that, and I don't really like NFS, but I have no other choice. Catalin Petrescu <catalin.petrescu gmail com>

[Dovecot] Manually creating dovecot- files after isync/mbsync mirror
by Dale Gallagher 18 Dec '12

18 Dec '12

Hi everyone I'm using isync 1.0.5 patched to do recursive folder listing and mirroring mail from an external party's IMAP server to a local Maildir, which will be accessed by Dovecot 2.0.9. In order to prevent IMAP clients from re-downloading their mail, when connecting to Dovecot, I'm busy writing a script to generate appropriate dovecot-uidlist and dovecot-uidvalidity files, per Maildir. isync stores the uid in the filename, so that's extractable, per message, and the uidvalidity and current max uid are stored in a file .uidvalidity, in each Maildir. I've read the docs here: http://wiki2.dovecot.org/MailboxFormat/Maildir Regarding the dovecot-uidlist header (first line) - I've tried to search for and figure out what exactly is meant by the "mailbox global uid" and once I do, how to manually generate the 128 bit hex variation of it? Could someone elaborate on this, please. How would omitting the global uid field, beginning with G, affect remote clients' syncing of mail? Is this field mandatory? I also see that Dovecot's uidvalidity is of the form 4df8a4e2, whereas isync uses an integer. I'd appreciate it if someone could elaborate on what Dovecot uses and whether I can convert one to the other? I'll post the full solution, once complete, and working. Thanks. Dale

Re: [Dovecot] Automatically Cleaning Kerberos Credential Cache Files

Ben Morrow writes: > In any case, it's likely that the delivery process looks in the user's > home directory even if delivery is to a separate mail spool, unless > you've taken steps to prevent this. I can confirm this. I think the reason is that dovecot changes to the user's home directory so that it has a place to dump core. This causes problem for my setup since I user per-user NFS mounts, so a delivery to an internal mailing list caused hundreds of NFS automounts. I patched this behaviour out, but there is probably a more elegant solution (unset MAIL_STORAGE_SERVICE_FLAG_ENABLE_CORE_DUMPS? How?).

[Dovecot] Removing configured SSL certificate file from disk while Dovecot is running spams syslog
by Nils 18 Dec '12

18 Dec '12

Hi! [root@mikan ~]# dovecot --version 2.1.12 When I remove the SSL certificate from disk while Dovecot is running, it spams syslog with the following log message over and over: Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory Dec 6 17:41:41 mikan dovecot: config: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 12: ssl_cert: Can't open file /etc/ssl/private/dovecot.pem: No such file or directory [...] Reporting that the certificate went away is fine and useful, but spamming the syslog over and over with hundreds of entries per second(!) is annoying. :( I know what I'm doing, so reporting it once per connection attempt or something is enough. Even if Dovecot just decides to terminate, that would be fine. But a denial of service attack on syslog is not nice. Configuration output follows below. All the best, Nils [root@mikan ~]# dovecot -n # 2.1.12: /etc/dovecot/dovecot.conf # OS: Linux 3.5.4-1-ARCH x86_64 auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose = yes listen = *,:: login_greeting = mail_location = maildir:~/.maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 10 } ssl_cert = </etc/ssl/private/dovecot.pem ssl_key = </etc/ssl/private/dovecot.key userdb { driver = passwd } protocol imap { imap_idle_notify_interval = 2 mins mail_max_userip_connections = 5 } protocol pop3 { mail_max_userip_connections = 5 pop3_logout_format = pop3_save_uidl = no pop3_uidl_format = %08Xu%08Xv }

[Dovecot] Documentation of Redis and Memcache Backends
by Urban Loesch 18 Dec '12

18 Dec '12

Hi, in the release notes of 2.1.9 I read that dovecot supports memcache and redis backends for userdb/passdb authentication. This is very interesting for me and should reduce queries and database load of our mysql servers. My idea is to use memcache or redis in our IMAP/POP3 proxies in front of our backend servers. So I would like to try out if it's possible to store proxy information of our backends. For example the backend ip adress. But in the wiki I found only a few configuration settings for redis backend. http://master.wiki2.dovecot.org/AuthDatabase/Dict Also the mentioned example config file "dovecot-dict-auth.conf.ext" with full list of configuration options does not exits in the source of 2.1.11. Have you any idea where I can find the full info or any howtos? Many thanks and regards Urban

[Dovecot] Error: unlink_directory(.../lucene-indexes) with doveadm index
by Fred Kilbourn 18 Dec '12

18 Dec '12

Hi, Per discussion on this previous thread: http://dovecot.org/pipermail/dovecot/2012-October/068849.html I am updating search indexes on all my mailboxes via a nightly cronjob that runs: doveadm index -A '*' The problem we're running into is that random mailboxes will throw the following error during the update (sanitized to conceal actual domain name): doveadm(user(a)domain.com): Error: unlink_directory(/var/spool/mail/domain.com/user/sdbox/lucene-indexes) failed: Permission denied We have around 250 domains on the server, with a handful of mailboxes on average in each domain. We get this for a varying number of total mailboxes (1 to 6 every night). It is common for the same mailbox to show up a few days in a row and then stop throwing the error. The script is running as root, so there shouldn't be any file level permissions. Any thoughts on the root cause of these errors? What can I provide to help further diagnose? Thanks, Fred Kilbourn

[Dovecot] Dovecot version 1.2.17
by Philip Coackley 18 Dec '12

18 Dec '12

Hello, I am currently performing retrospective upgrades to an old ubuntu 9.10 Karmic Kola server. I need to upgrade dovecot 1.1.11 to 1.2.17 then to 2.0 etc. I have downloaded the binaries and run ./configure make make install. Dovecot compiles OK however I can not get the ./configure options to install at the following locations: executable: /usr/sbin/ config: /etc/dovecot/ Question: What are the ./configure options to do this? What are the ./configure options used to create the executable for unbuntu? (especially 9.10 if different). Reason for upgrade is auth-login errors every 2-3 weeks with 1.1.11 - looking at the release descriptions, this should fix this and the memory leaks! Phil Coackley

I still run using mbox, and have not had a problem with corruption, however, this is probably owing to our modest IMAP demand and careful coordination of file locks among all the different MUAs. You're better off with Maildir and other formats, that are better designed for simultaneous access. There are other good reasons to switch formats. Dovecot also supports its own mdbox/sdbox for high performance: its a hybrid that tries to incorporate the best of both words. More info http://wiki2.dovecot.org/MailboxFormat > After those questions, it's just a "what do you think the pros and cons > of each are?" I can't speak to the other software you are looking at, but two factors I found to be particularly good: - flexibility: you can get almost every oddball setup to work. Migration from uw-imapd is fairly easy, but then again, uw-imapd didn't have a lot of knobs to turn. Plugins are available that extends its functionality. - support: this mailing list is great, and Timo is an absolute wizard in getting bugs fixed. (Note: I am shamelessly buttering him up so that he fixes the outstanding bug I reported!) Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] need help with dovecot-lda
by Andreas Meyer 16 Dec '12

16 Dec '12

Hello all! Some month ago I upgraded our dovecot installation from version 1.0.5 to version 2.1.7 without having any trouble. Postfix is delivering email directly per virtual transport to the maildirs and mailboxes of the users in /var/spool/vhosts/domains/.... Now I want to use dovecot-lda and created a new entry in the master.cf of postfix. dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} It is not clear to me, how the dovecot-lda is started bei dovecot and you it finds the socket dovecot postfix created. The dovecot.conf looks like this; # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.22.5-31-bigsmp i686 openSUSE 10.3 (i586) ext3 auth_verbose = yes disable_plaintext_auth = no log_path = /var/log/dovecot1 mail_location = mbox:/var/spool/vhosts/%d/dovecotprivate/%n:INBOX=/var/spool/vhosts/%d/%n !include /etc/dovecot/conf.d/*.conf passdb { args = /etc/dovecot/passwd driver = passwd-file } userdb { args = /etc/dovecot/passwd driver = passwd-file } ssl_cert = < /etc/dovecot/ssl/hostcert.pem ssl_key = < /etc/dovecot/ssl/hostkey.pem #verbose_ssl = yes plugin { quota = maildir:User quota quota_rule = *:storage=500MB # 10% of 1GB = 100MB quota_rule2 = Trash:storage=+10%% # 20% of 1GB = 200MB # quota_rule3 = Spam:storage=+20%% autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = Sent } I set soft_bounce = yes in main.cf of postfix and delivery of mail fails with Dec 14 16:13:34 delta postfix/virtual[14082]: BBC0F1B31294: to=<xyz(a)anup.de>, relay=virtual, delay=395, delays=395/0.01/0/0.13, dsn=4.1.1, status=SOFTBOUNCE (unknown user: "xyz(a)anup.de") This is the relevant part of the main.cf: dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = anup.de bit-corner.de bitcorner.de baubetreuung-meyer.de saxelektro.de virtual_mailbox_base = /var/spool/vhosts #virtual_mailbox_maps = hash:/etc/postfix/vmailbox #virtual_minimum_uid = 100 #virtual_uid_maps = static:5000 #virtual_gid_maps = static:5000 virtual_mailbox_limit = 524288000 virtual_transport = dovecot I don't get it right. As far as I understand postfix uses virtual_transport = dovecot and hands the mail over to the socket dovecot. But how does dovecot know where to look for the socket. I am missing somthing but don't know what. Any help is appreciated! Andreas

[Dovecot] Dovecot "sleep" for short snapshots
by Peer Heinlein 15 Dec '12

15 Dec '12

Making consistent backups from Dovecot with mdbox requires a snapshoted filesystem with (at least) a short Downtime for Dovecot. I'd like to avoid killing several thenthousand IMAP-sessions for 60 seconds. Users don't like that... And the admin dislakes that too... What about a "short sleep" mechanism for Dovecot, where all writes are finished and new writes are easily delayed? I'd like to following process: *) "doveadm sleep" puts Dovecot in sleep-Mode: -- All existing writes are finished (before "doveadm sleep" is allowed to exit) -- All new writes are simply delayed -- All readonly-operations could work normally, so users can fetch and read mails *) The the admin can create a LVM-/SAN-snapshot of the filesystems *) "doveadm unsleep" will finish the magic Overall the whole process will take just some seconds. Users will recognize a simple write-delay, but they can work normally and the aren't unconnected at all. If the snapshot is really fast the users won't recognize the whole situation at all.

[Dovecot] More detail re dovecot-uidlist and -uidvalidity files
by Dale Gallagher 13 Dec '12

13 Dec '12

Regarding the dovecot-uidlist header (first line) - I've tried to search for and figure out what exactly is meant by the "mailbox global uid" and once I do, how to manually generate the 128 bit hex variation of it? Could someone elaborate on this, please. How would omitting the global uid field, beginning with G, affect remote clients' syncing of mail? Is this field mandatory? Would "3 V$uid_validity N$next_uid" be sufficient to ensure that clients don't re-download everything? I also see that Dovecot's dovecot-uidvalidity is of the form 4df8a4e2, whereas the IMAP syncing utility which I'm using (isync) uses an integer. I'd appreciate it if someone could elaborate on what Dovecot uses and whether I need to convert one to the other (ie. after syncing with isync, do I need to convert it to work with Dovecot? Thanks.

It's typical. Some popular mail readers open about 5, some more, some less. I set my mail_max_userip_connections at 12 even though there are some users who regularly bump up against this. They don't seem to notice -- dovecot probably bumps off the least recently used connection and their mail reader reconnects if it needs to open that mailbox again. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] rare ssl issue
by Eduardo Casarero 12 Dec '12

12 Dec '12

I'am having a rare situation with ssl connections. I can connect to 993/995 but the connection never starts. >From the client side i test with: $ openssl s_client -connect example.com:993 CONNECTED(00000003) and stays like that... waiting. In the other side i see in dovecot logs: Disconnected: Inactivity (no auth attempts): rip=x.x.x.x, lip=x.x.x.x, TLS handshaking this happens from some networks only, so i think that mi isp (where the server is hosted) is doing some kind of shaping. But if i try to connect to port 465 for example, or 443 it works like a charm. i am talking to my isp, but i thougth that someone may have a hint or any comment that could help. regards, eduardo.

[Dovecot] dovcot+offlineimap+gmail: INBOX empty, mail doubled
by Uwe Brauer 11 Dec '12

11 Dec '12

Hello I have used for years offlineimap-6.2.0 dovecot-imapd 1:1.2.9 in Kubuntu 10.04 Together with a imap server of my university. Yesterday we switched to google, which I know, is not a real imap server. I have 2 problems and the first I think has to do with either an old version of offlineimap or a bad configuration file: - All folders are downloaded+ Gmail[All Mail] so doubling my mail. - My INBOX folder is empty, however this is the only folder for which offlinemap gives the following warning: Syncing INBOX: Gmail -> MappedIMAP WARNING: UID validity problem for folder INBOX (repo UniLocal) (saved 1309334376; got 1355232397); skipping it So maybe this is also a offlineimap fault. In any case I have googled around and found out that I am not the only person suffering this problem. I have attached my configuration file in the hope that may be somebody could give me a hint.

Each user has one credential cache file in /tmp on the mail server after logging into Dovecot. We aren't using randomized names, so everything is in the standard format /tmp/krb5cc_uid. We do use KRB5 authenticated (and encrypted) NFS, but we don't deliver mail to home directories. Since all users are "real" users, and our office size is small, everyone has a mail spool directory on the mail server. Postfix is configured to use Dovecot for Kerberos. The relevant lines in its /etc/postfix/main.cf are as follows: smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated, reject smtpd_sasl_security_options = noanonymous >> Currently, I have a cron job deleting the files manually every night. >> Obviously, this is a cruddy solution. > Well, I don't know about that: obviously, it would be a good idea to > work out what's going on here, in case it causes anything else to go > wrong, but a cronjob clearing out /tmp is a good idea in any case. Fair enough. And of course, I get a cache file every time I use sudo or log in through a GUI. Those aren't cleaned up either! Maybe I should be deleting credential cache files on all the machines every night. Those cache files have never given me a problem, though. >> I have Dovecot configured on a >> RHEL 6 box.

I've tried session=yes by itself, but I don't think I've tried it with setcred=yes.

No random portion (the only application we have configured with random ccache names is SSH), just the usual /tmp/krb5cc_uid. Permissions appear correct, they belong to the appropriate user and group accounts. The SELinux permissions are set to: system_u:object_r:user_tmp_t:s0. This is different from the machine's credential cache (system_u:object_r:gssd_tmp_t:s0), but I've disabled and re-enabled SELinux during different parts of my testing and didn't notice any errors. Using GSSAPI directly doesn't create any cached credential files on the server. However, I just verified that I'm still sporadically getting the duplicate tickets (two lines for imap/hostname.server.com(a)SERVER.COM, with identical expiration dates). It comes and goes. I have a few users testing it for me, and they'll let me know if their logins break tomorrow like they have in the past once the normal log in period elapses. Since the "fix" for that problem is to log into the mail server, I have a hard time testing for the problem myself (being logged into the mail server nearly continuously just now). > What happens if you log in as an ordinary user (preferably using the > same PAM stack as Dovecot uses), use klist to find the ccache name and > 'ls -i' to find its inode number, then manually kinit again?

I've noticed that the ccache files for regular users do not get deleted when they log out. On another user's workstation, I found a ccache file for my account from a week ago (my current session was using a randomly generated SSH ccache file). I ran a command with sudo to force it to reauthenticate with pam_sss, and the timestamp on the ccache file was updated and the inode changed. My best guess is that pam_sss.so just doesn't do ccache cleanup. > Ben > Thanks for taking a look, I appreciate all the suggestions. This problem's been driving me up a wall for weeks now. I only just managed to narrow down the cause in the last few days. If I can't get a fix working in Dovecot, I'll try tackling it from a different perspective. I understand why Dovecot might not be cleaning up credential files (especially if it's just calling PAM normally), but I definitely do not understand why Postfix is behaving the way it does. If I can just get GSSAPI to work, I could probably bypass the problem as well. - Maura Dailey maura(a)eclipse.ncsc.mil

[Dovecot] Switch from MySQL/CourierMail to MySQL/Dovecot
by Robert Moskowitz 11 Dec '12

11 Dec '12

Hello, new here. I am a Centos/Fedora user, and for the past 3 years have been running my mail server using Postfix/MySQL/CourierMail/Squirrelmail on Fedora. The current incantation of the tutorial is at: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-my… Well it is time to rebuild my mailserver; this time on Centos 6.3. My goal is to use supplied rpms, not to build my own (and rebuild everytime there is an important update). So I am pulling quotas which has been a pain anyway, and I am investigating using Dovecot in place of CourierMail. In Centos 6.3, the version of Dovecot is: 2.0.9-2 I am looking for a tutorial to assist in the setup, as I am nowhere an expert on any of this (I am a communications security expert in the IETF and IEEE 802). There are a couple items that I have come to depend on in my current setup that are musts in anything new: Virtual user/domain That is, not only virtual domains, but also users defined by domain. So in the MySQL user table, the email value is set to user@domain. Thus a user can receive/send mail from multiple domains with the same addr and only those domains defined for the user in the user table. Obviously there is no coupling of Linux user accounts and email accounts. CourierMail is storing mail under /home/vmail/domain/user/... Encrypted passwords The passwords in the user table in MySQL are encrypted. This will be used to auth the user for POPing or IMAPing and sending their mail. I have encountered a few tutorials where it seems like passwords are stored in the clear? Anyway, not much else! Well as far as the user interface is concerned. Postfix with clamav and spamassassin and maybe one or two extras. And SquirrelMail for Webmail. A better gui than phpMyAdmin for maintaining the tables would be nice, but I don't have a lot of users, so it works well enough. Can someone point me to a tutorial best suited to my needs? Also any firewall rules, as I don't want to turn off iptables (and ip6tables) and any SELinux policy rules to add. Oh, and IPv6 will be a must in the near future, so anything needed to ensure IPv6 working right as well. Thanks

[Dovecot] Automatically Cleaning Kerberos Credential Cache Files
by Maura Dailey 10 Dec '12

10 Dec '12

I'm in a situation here at work where I'm trying to support a mixed network of OS X and RHEL desktop machines with a Postfix/Dovecot combination. - user account information is stored in LDAP - user credentials are in MIT Kerberos - server is running RHEL 6/Dovecot 2.0.9/Postfix 2.6.6 I am currently using the PAM passdb module to authenticate my users (I began to have trouble with using GSSAPI directly). After I implemented it, a few weeks later, I noticed that some users were no longer getting their mail if they hadn't logged in during the past day. Postfix's mailq showed that hundreds of messages were backing up in the queue. I eventually tracked it down to leftover Kerberos credential cache files (/tmp/krb5cc_????) sitting in /tmp on the mail server. The presence of expired credential files was preventing Postfix from delivering mail to those users' mail spools. If I delete the credential files manually, Postfix immediately delivers the queued emails. Currently, I have a cron job deleting the files manually every night. Obviously, this is a cruddy solution. I have Dovecot configured on a RHEL 6 box. The Pam stack on a RHEL 6 machine uses sssd (pam_sss.so) for authentication with Kerberos, not pam_krb5.so. I'm trying to track down which piece of the puzzle is responsible for cleaning up leftover credential caches. Is there a configuration option I can pass to Dovecot's passdb directly to clean up these cache files? Do others generally have more success using a custom PAM stack with pam_krb5.so instead of pam_sss.so? Poring over sssd's configuration options didn't reveal anything useful. I'm still not sure why Postfix even cares if there are expired credential cache files in /tmp at all. I'm back to trying GSSAPI directly again as well in the meantime on a few test clients. When I used that in the past, users were getting issued duplicate Kerberos tickets and users were forced to log into the mail server directly using SSH after a day in order to get their mail to work (seemingly a related issue). If I get those same errors again, I'll start another thread.

[Dovecot] dsync help?
by Torbjorn Astlind 10 Dec '12

10 Dec '12

Hi all, I have dovecot serving aprox 200 users through mbox, but the time has come to migrate to a new server, and to use Maildir. Using rsync from the old server I get all user data, i.e /home/*, and inboxes i.e /var/mail/* to a new server. This has worked well for some time as backup. The dsync should convert everything to Maildir, and it does... to an extent. (linebrakes for easy viewing) What I see, is that often, the /home/mail/xxx is NOT resulting in /home/xxx/Maildir/cur All mailboxes from /home/xxx, are properly converted to /home/xxx/Maildir/.name_of_ box Am I misunderstanding something? I get it to work sometimes if I delete the ~/Maildir completely before doing the dsync. All, and any help most welcome, Torbjörn for i in `cat /home2/torbjorn/SCRIPTS/userlist.txt`; do dsync -D -v -f -u $i -c /etc/dovecot/alt_config/10-mail.MBOX.conf backup maildir:~/Maildir; done > /home2/torbjorn/SCRIPTS/mb2mdRES.txt 2>&1 the -c 10.mail.MBOX.conf contains, the parts I think are relevant for the dsync operation: mail_location = mbox:~/home:INBOX=/home/mail/%u namespace { type = private separator = '/' inbox = yes } dsync(root): Debug: Effective uid=501, gid=501, home=/home/torbjorn dsync(root): Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/home:INBOX=/home/mail/torbjorn dsync(root): Debug: fs: root=/home/torbjorn/home, index=, control=, inbox=/home/mail/torbjorn, alt= dsync(root): Debug: Effective uid=501, gid=501, home=/home/torbjorn dsync(root): Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir dsync(root): Debug: maildir++: root=/home/torbjorn/Maildir, index=, control=, inbox=/home/torbjorn/Maildir, alt= dsync(root): Debug: Namespace : /home/torbjorn/Maildir doesn't exist yet, using default permissions dsync(root): Debug: Namespace : Using permissions from /home/torbjorn/Maildir: mode=0700 gid=-1 dsync(torbjorn): Debug: Namespace : Using permissions from /home/torbjorn/home: mode=0700 gid=-1

[Dovecot] IMAP instead of Maildir on Ubuntu Precise
by Thufir 10 Dec '12

10 Dec '12

Why is dovecot using Maildir and not IMAP. Or is it using even using Maildir at all? Currently I'm using mailman, postfix and dovecot to manage a mailing list. Mail is sent to thufir(a)dur.bounceme.net which the "mail server delivery agent stack provided by Ubuntu server team" of dovecot-postfix handles fine, keeping it locally, so far as it goes. The mail ends up in /home/thufir/Maildir, which the balsa mail client reads fine, as it handles Maildir fine. However, I would like to use dovecot-imapd which is installed. However, it's not clear quite how to switch over to IMAP. I see: root@dur:~# root@dur:~# nl /usr/share/dovecot/protocols.d/imapd.protocol 1 protocols = $protocols imap root@dur:~# root@dur:~# grep protocol /etc/dovecot/dovecot.conf # Enable installed protocols !include_try /usr/share/dovecot/protocols.d/*.protocol root@dur:~# which indicates to me that IMAP is configured. So, why is mail showing up using Maildir? I'm looking at: "Once you have chosen, amend the following line in the file /etc/dovecot/dovecot.conf: protocols = pop3 pop3s imap imaps" https://help.ubuntu.com/community/Dovecot Admittedly, I've not looked too closely into Dovecot man pages as I don't want to get too deep into the weeds on that if it's not even Dovecot I need to configure. I'm assuming that it's dovecot which is using Maildir: root@dur:/etc/postfix# root@dur:/etc/postfix# grep dovecot main.cf smtpd_sasl_type = dovecot smtpd_sasl_path = private/dovecot-auth mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/conf.d/01-mail-stack-delivery.conf -m "${EXTENSION}" root@dur:/etc/postfix# Can I force dovecot to only ever use IMAP and never use anything else? Is it maybe postfix which is using Maildir, and this is why my mail shows up as Maildir type mail? thanks, Thufir thufir@dur:~$ thufir@dur:~$ head .balsa/config -n 20 [mailbox-Inbox] Path=/var/mail/thufir Type=LibBalsaMailboxMbox Name=Inbox [mailbox-Outbox] Path=/home/thufir/Maildir/outbox Type=LibBalsaMailboxMbox Name=Outbox [mailbox-Sentbox] Path=/home/thufir/Maildir/sentbox Type=LibBalsaMailboxMbox Name=Sentbox [mailbox-Draftbox] Path=/home/thufir/Maildir/draftbox Type=LibBalsaMailboxMbox Name=Draftbox thufir@dur:~$

[Dovecot] Performance problems while running doveadm purge
by Jost Krieger 08 Dec '12

08 Dec '12

I have a rather large and active mdbox (28 GB, 3M mess, 1200 deliveries/day). I usually have no problems working with those mails, and there is some batch processing going on (via doveadm). Every few weeks I try my luck running doveadm purge, and this a) crunches about 5GB (to be expected), b) takes rather long (ok), c) leads to long stretches of blocked mdbox, which is the problem. I always turn off the batch processing, but deliveries take so long that they sometimes give up after timeout (they will come back later), and the IMAP clients get blocked for long minutes. Sometimes even the purge run aborts because of 3-minute-timeouts. What could be going on here (2.1.10)?

[Dovecot] Cannot STORE \Seen flag on some mails
by Frerich Raabe 07 Dec '12

07 Dec '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD (exact output of 'dovecot -n' is atttached to this mail). The machine is serving a public mailinglist archive which is read-only; all mail arriving for the archive is marked as \Seen using Sieve script. This setup works well most of the time, but I noticed that for *some* mails, the \Seen flag doesn't seem to be stored. Right now I have 31255 mails in one of my folders and I can't seem to mark five of them as \Seen - the others work just fine. I first suspected a client issue so I did a little IMAP session by hand: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. . LOGIN "xxxxxx" "yyyyyy" . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in .

SEARCH UNSEEN * SEARCH 27126 27127 28484 29835 29838 . OK Search completed (0.000 secs). . LOGOUT * BYE Logging out . OK Logout completed. Note how the first 'SEARCH UNSEEN' command shows that '27126' is unseen, the subsequent 'STORE' command succeeds - but then 'SEARCH UNSEEN' still shows 27126 as unseen! I have all four logging levels being piped to /var/log/maillog (I verified this by running dovecot --log-error) but the file does not show any problems. I checked the file permissions of the Maildir directories, and it all looks dandy to me. Does anybody have some suggestions how to debug this further, or what the reason for this may be? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

Hello, I am in charge of migrating our mail system from dovecot to another server, and I am having to write a script to do this as tools like imapsync are too slow. What I am trying to find is the definitions of the flags that dovecot adds to the Maildir file name it uses for the IMAP messages. For example what the a and b mean in the following: 1176236036.P7260Q1438.sucia:2,RSab I am looking for all definitions not just a and b. Thanks Chris chris(a)rosepointnav.com

06 Dec '12

I have a small mail server with virtual users. In my /etc/dovecot/conf.d/10- mail.conf I have this setting: mail_location = maildir:/var/mail/vhosts/%d/%u which is also the home location of each user. Now I learned that this is not the prefered configuration, and in fact some of my sieve subdirectories are mistaken as mail directories. While I understand that I have to create separate mail subdirectories in each user folder, I am not sure where I have to adapt the dovecot configuration files. I could not find a guide, only some scattered hints and of course http://wiki2.dovecot.org/VirtualUsers/Home I guess I have to shut down the server for the reconfiguration, or is there a way to do it on a life system?

[Dovecot] When are search indexes updated?
by David Abrahams 06 Dec '12

06 Dec '12

I noticed that occasionally searching in my huge archive mailbox can be really slow, so I tried doveadm index on it and it seemed to do a lot of work, which seemed strange given, for example, that dovecot-lda says it keeps Dovecot index files up-to-date. Then I thought, "maybe these are different files than the search indices." If so, that's not entirely clear from the docs and Wiki. So, questions: * When are search indexes updated? * Are they updated incrementally? * If not, why not? * If so, why would a mailbox's index drift out-of-date, as mine had? BTW, I'm using the clucene search backend. -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] dovecot backend on director ?
by Thomas Hummel 05 Dec '12

05 Dec '12

Hello Timo, The last time I checked my understanding about director was that : 1. backend/"real" imap servers should not be on the same host (or the same dovecot instance) to avoid proxying loops. Is it still the case with the latest 2.1 stable release ? Is there a plan to be able to run director and real server on the same host, thus requiring only 2 hosts instead of 4 to have load balancing and a redundant director ? 2. director itself was not able or meant to check if one of the real server was down (some script was pointed long time ago in this list). Same questions. 3. you'll have to use dovecot lmtp instead of let's say procmail. Would deliver be still a choice or is lmtp the only deliver compatible choice ? In what case would lmtp be more useful than deliver ? To have some sort of "remote LDA" ? By the way, what gets indexed on deposit on the mailbox since, by definition, the user has not done any request yet ?

[Dovecot] Quotas 2.1clarification
by Nick Edwards 05 Dec '12

05 Dec '12

Timo, I have much suspicion that our quota system is not working correctly since we migrate to 2.1 Currently using 2.1.10 Previously we had for issue of warnings quota_warning = storage=90%% /scripts/dqwarn-90.sh quota_warning2 = storage=75%% /scripts/dqwarn-75.sh worked great, these lines also migrated to new conf upon conversion. But quota conf example shows plugin { #quota_warning = storage=95%% quota-warning 95 %u #quota_warning2 = storage=80%% quota-warning 80 %u } # Example quota-warning service. The unix listener's permissions should be # set in a way that mail processes can connect to it. Below example assumes # that mail processes run as vmail user. If you use mode=0666, all system users # can generate quota warnings to anyone. #service quota-warning { # executable = script /usr/local/bin/quota-warning.sh # user = dovecot # unix_listener quota-warning { # user = vmail # } #} So this seems to indicate /scripts/dqwarn-75.sh should be a service name, which then calls the service quota-warning with that script in it etc etc etc surely this old 4 line method has not been replaced into a 20 line mess? Is this old way still functioning as I suspect it is not, and we need to write up two separate new quota warning services given our warnings are worded differently, or should the old methods still be working as they did in 1.2 and we have an error elsewhere?

[Dovecot] Maidir layout : why and how ?
by Thomas Hummel 04 Dec '12

04 Dec '12

Hello Timo, I've been using dovecot from many years now using Maildir mailbox format with default layout (Maildir++, everthing in a single directory). What would be the reason(s) to convert to Layout=fs ? I can only think of one : to allow dots in mailbox names. And even in that case, I guess I still have the option to use the litescape plugin. Besides, how would one process to do the conversion ? Using dsync ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Groupe Exploitation et Infrastructure

[Dovecot] CVE-2012-5620
by Timo Sirainen 04 Dec '12

04 Dec '12

This CVE isn't worthy of existence. A user can crash his/her own IMAP session by issuing a specific SEARCH command, which is just slightly worse than user issuing a LOGOUT command. It took years for people to notice this bug, because just about no IMAP client issues such a command.

[Dovecot] imap-login hanging when firewall blocks ssl handshaking
by Erik A Johnson 04 Dec '12

04 Dec '12

imap-login processes are hanging (using 100% of CPU) when connected from a client that is partially blocked by a firewall. It appears that imap-login is stuck in a loop trying to complete an ssl handshake. imap-login is working fine for other clients not blocked by the firewall (including localhost). This is dovecot 2.1.10 under Mac OS X 10.8.2 (compiled from sources); the firewall is Little Snitch 3.0.1 blocking port 993, which appears to let the connection initiate but then squashes and disconnects the socket during ssl handshaking. gdb backtrace and Activity Monitor's "Sample Process" show that imap-login is stuck calling ioloop-kqueue's io_loop_handler_run -> io_loop_call_io -> ssl_step repeatedly; dtruss shows that it is repeatedly making system calls to kevent and read, the latter returning -1 with errno 57=ENOTCONN="Socket is not connected". (I also tried ./configure --with-ioloop=poll and --with-iopoll=select instead of the default best = kqueue but the results were the same; --with-iopoll=epoll didn't work because epoll is not available on this machine.) The client, initiated by the command "openssl s_client -connect SERVER:993", first responds "CONNECTED(00000003)" but then immediately the error "60278:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-44/src/ssl/s23_lib.c:182:". The infinite loop is in src/lib/ioloop.c in the function "io_loop_run" where the statement "while (ioloop->running) io_loop_handler_run(ioloop)" is executed. While I think the firewall is not doing the right thing (i.e., it lets a connection start but then kills it), it seems that imap-login should fail gracefully when the socket is no longer connected.

[Dovecot] clucene (in)stability

I'm going to try CLucene 0.9.21, which they claim has been "proven to be stable over time" (see http://clucene.sourceforge.net) and see how it works out. I wonder if there's a future envisioned for FTS with Dovecot that's suitable for small installations (i.e. doesn't require a Solr server) and has a good chance of correctness and stability? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] Thunderbird SSL/TLS client authentication fails
by Roger Hunen 03 Dec '12

03 Dec '12

Hi, This is my first post to the list, so greetings to you all! I am seeking your help with SSL/TLS client authentication. I currently have the following setup: * Server: - Debian Squeeze (fully patched) - OpenSSL 0.9.8o - Dovecot v2.1.10 (Debian backport package from Wheezy) - SSL listener on port 993 with the Dovecot selfsigned certificate that was created during installation - Virtual users (user(a)domain.net) with password in passwd style file * Client: - Windows XP SP3 (fully patched) - Thunderbird 17.0 - IMAP account using "Normal password" authentication - Roundcube webmail (to be added soon) This works just fine :) ==> I now want to set Thunderbird to use "TLS certificate" authentication so that I can safely expose port 993 to the internet for mobile use. The idea is that clients with a trusted client certificate do not need a password so that I can change my password for Roundcube without having to change passwords on other IMAP clients (Roundcube will connect to localhost without SSL). To do so I did the following: - use XCA (v0.9.3, Windows version) to setup a private root CA with a CRL - export root CA certificate and CRL in PEM format and join them into a ca.pem file (order: certificate, CRL) - configure Dovecot to use the ca.pem file and require a client certificate - use XCA to generate a private key and certificate for commonName=user(a)mydomain.net - import certificate and private key into Thunderbird - change IMAP account setting in Thunderbird to use "TLS Certificate" authentication - When prompted, select the imported certificate to be used for authentication. Unfortunately the authentication fails :( Using "verbose_ssl=yes" I can see in the Dovecot logfile that Thunderbird connects and that the SSL handshake completes successfully. "Valid certificate" is logged for both client certificate and root CA certificate. This looks "so far so good" to me :) The Dovecot log has the following lines at the point of failure: imap-login: Warning: SSL alert: where=0x4004, ret=256: warning close notify [<IP>] imap-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [<IP>] imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=<IP>, lip=<IP>, TLS, session=<ID> (IP address and TLS session ID removed) The last log line ("user=<>") suggests that Dovecot does not try to use the commonName from the client certificate as the username even though (I think) I have configured Dovecot to do so. The relevant lines in the Dovecot configuration are: <config> auth_mechanisms = plain auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes disable_plaintext_auth = yes protocols = imap ssl = yes ssl_ca = </etc/dovecot/ssl/ca.pem ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cert_username_field = commonName ssl_key = </etc/ssl/private/dovecot.pem ssl_parameters_regenerate = 0 ssl_require_crl = yes ssl_verify_client_cert = yes service imap-login { chroot = login process_min_avail = 1 service_count = 1 inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } </config> Observation: with "auth_ssl_require_client_cert = yes" Dovecot requires Thunderbird to send the client certificate even when Thunderbird uses "Normal password" authentication (authentication only fails if I delete the certificate from Thunderbird). So the SSL part looks OK to me. It seems that Dovecot is waiting for the client to logon over the established SSL/TLS connection instead of taking the username from the commonName in the certificate. ==> What could be going wrong here? I can post full config and logfile lines if you wnt to. Except for some possible oversight on my behalf there is nothing secret in there (I just didn't want to add too many lines to this already long post). Regards, -Roger

[Dovecot] Redelivery of mdbox messages to pass through sieve
by Hugh Davenport 01 Dec '12

01 Dec '12

Hey, I've been slack and haven't updated my sieve script for yonks, and finally got round to it. What I was wondering is whether there was a way to basically take all the messages from a folder and pass it through sieve again. I've found earlier messages in this list, but they were for Maildir format, not mdbox which I use now. Does anyone know of a way to do this? Cheers, Hugh

[Dovecot] Maildir conversion
by Aristidis Fesarlis 30 Nov '12

30 Nov '12

Hi all, I am using Dovecot 1.2.7, and trying to do my first Mbox to Maildir conversion. So I created a small script: > #!/bin/bash > > ls > userlist.txt > > for i in `cat userlist.txt`; do > echo "---------------------"; > echo "Converting user $i..."; > echo "---------------------"; > > su - $i -s /bin/bash -c "/opt/scripts/mb2md.pl -s mail -R"; > su - $i -s /bin/bash -c "/opt/scripts/mb2md.pl -m -s > /var/mail/$i"; > su - $i -s /bin/bash -c "cp ~$i/mail/.subscriptions > ~$i/Maildir/subscriptions"; > done > > rm -f userlist.txt I would like some help with the following: 1. Trying it, I get multiple warnings for some mailboxes like this: > "WARNING: UID from X-UID: header too low. Ignoring it Is this a problem? Or I can ignore it? 2. I understand that I also have to instruct my MDA (procmail) to deliver mail to the new location. I found that I have to create an /etc/procmailrc with the following line: > DEFAULT=$HOME/Maildir/ My question is: Some users have their own .procmailrc file inside their home directory, to filter mail etc. Their file does not contain the above statement. Would the default procmailrc file be processed for them as well? Or their file takes precedence, causing the default file not to be processed at all? Thank you

[Dovecot] Newbie Basic ACL issue

i can not impliment a basic acl to a /public/.News folder. however with out ACL it works great but after implementing acl "Public" folder can be seen while subscribing but i can not create folder inside it nor i can view already created ".News" folder. when i restart dovecot it shows me some thing like this root@mailsrv:/public/.News# /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecotILoading modules from directory: /usr/lib/dovecot/modules/imap IModule loaded: /usr/lib/dovecot/modules/imap/lib01_acl_plugin.so IModule loaded: /usr/lib/dovecot/modules/imap/lib02_imap_acl_plugin.so IEffective uid=65534, gid=65534, home=/tmp Iacl: No acl_shared_dict setting - shared mailbox listing is disabled root@mailsrv:/public/.News# dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir:INBOX=~/Maildir/:INDEX=~/Maildir/index mail_debug: yes mbox_write_locks: fcntl dotlock mail_plugins: acl imap_acl namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: Public/ location: maildir:/public:INDEX=/public/index list: yes subscriptions: yes lda: mail_plugins: acl auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: acl: vfile as i read in few howto's that "dovecot-acl" file should be placed in the mail publish folder like in my case "/public/.News/dovecot-acl" here is the output of my file root@mailsrv:/public/.News# cat dovecot-acl owner lrwstipekxa anyone= lr now after this implimentation i can see the folder "Public" in subscription now when i try to create a new folder inside ".News" folder via outlook 2007 it says "cannot move the item. the server responded: 'NOPERM] Permission denied" i think i am messed up permission actually i have 2 users "tom" and "fmaster" both doing the same thing. weather i write this "anyone lrwstpekxa" or "user=tom lrwstpekxa" it does the same for both user what i want is just a simple thing. i want tom to be the owner of .News and fmaster has read only. so he can only read the news but can not delete even can not change the flag to read or unread.

30 Nov '12

http://dovecot.org/releases/2.1/dovecot-2.1.12.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.12.tar.gz.sig The dovecot-config file installed by v2.1.11 was missing quotes, which broke building Pigeonhole. This release fixes that.

30 Nov '12

http://dovecot.org/releases/2.1/dovecot-2.1.11.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.11.tar.gz.sig * lmtp/lda: dovecot.index.cache file is no longer fully mapped to memory, allowing mail deliveries to work even if the file is huge. * auth: userdb passwd lookups are now done by auth worker processes instead of auth master process (as it was documented, but accidentally didn't work that way). + lmtp: lmtp_rcpt_check_quota=yes setting checks quota on RCPT TO. - lmtp: After successful proxying RCPT TO, the next one to a nonexistent user gave tempfail error instead of "user not found". - lmtp proxy: Fixed hanging if remote server was down. - imap: Fixed crash when SEARCH contained multiple KEYWORD parameters. - doveadm: Various fixes to handling doveadm-server connections. - -i <instance name> parameter for Dovecot tools didn't work correctly. - director was somewhat broken in v2.1.10. This version also includes various reliability enhancements. - auth: passdb imap was broken in v2.1.10.

[Dovecot] mdbox corruption

Trying to clean up the last of the corruption caused by my own stupidity. I now have two mailboxes for one user that give errors such as: doveadm(fax(a)amfes.com): Error: zlib.read(/var/mail/amfes.com/fax/mdbox/storage/m.9): gz trailer has wrong CRC value at 20065618 doveadm(fax(a)amfes.com): Error: read(/var/mail/amfes.com/fax/mdbox/storage/m.9) failed: Invalid argument (uid=238) doveadm(fax(a)amfes.com): Error: zlib.read(/var/mail/amfes.com/fax/mdbox/storage/m.9): corrupted data at 20145217 [...] doveadm(fax(a)amfes.com): Error: read(/var/mail/amfes.com/fax/mdbox/storage/m.20) failed: Invalid argument (uid=5155) doveadm(fax(a)amfes.com): Error: zlib.read(/var/mail/amfes.com/fax/mdbox/storage/m.20): corrupted data at 24779604 doveadm(fax(a)amfes.com): Error: Cached message size smaller than expected (1259 < 1260) doveadm(fax(a)amfes.com): Error: Corrupted index cache file /var/mail/amfes.com/fax/mdbox/mailboxes/INBOX/2010/dbox-Mails/dovecot.index.cache: Broken physical size for mail UID 5158 'doveadm force-resync' does not appear to fix these. There appear to be only the two mdbox files affected and I see about 40 errors. I would prefer to salvage as much as possible of these. What options do I have? Do a dsync to another location and take whatever I get? -- Daniel

[Dovecot] Missing Messages on IOS device
by David Morsberger 29 Nov '12

29 Nov '12

Resending because I didn't get any responses from my first post: I just converted my old server running UW/Panda to a Mac Mini Server running Mountain Lion (ML) Server. I'm using the postfix / dovecot setup provided by Apple. My IMAP clients are not showing all my emails. The Mail App on my iPhone and iPad is behaving the worse. I can see the emails that are not showing up in the cur directory. The ML Mail App is stating there are 3854 emails in my INBOX. There are 3948 files in the 'cur' directory ('ls cur | wc -l' returns 3948). Other mailboxes and directories have the same behavior. I'm not sure what to expect here. My method of conversion was to bulk copy (drag and drop) all the messages from one the UW server to the Dovecot server using the Apple Desktop Mail App in Mountain Lion. Any idea why these messages are not showing up on my devices and how I can get them to show up? bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd --version 2.0.19apple1 bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd -n # 2.0.19apple1: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 hfs aps_topic = com.apple.mail.XServer.fc3bb7c3-c8ef-4fe2-aff3-95ecd927fb11 auth_mechanisms = cram-md5 x-plain-submit plain login apop digest-md5 auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n default_internal_user = _dovecot default_login_user = _dovenull disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 6 mail_access_groups = mail mail_location = maildir:/Library/Server/Mail/Data/mail/%u mail_log_prefix = "%s(pid %p user %u): " mail_plugins = quota zlib fts fts_sk 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 ihave mdbox_rotate_size = 200 M passdb { args = /Library/Server/Mail/Config/dovecot/submit.passdb driver = passwd-file pass = yes submit = yes } passdb { driver = od } plugin { fts = sk quota = maildir:User quota quota_warning = storage=100%% quota-exceeded %u sieve = /Library/Server/Mail/Data/rules/%u/dovecot.sieve sieve_dir = /Library/Server/Mail/Data/rules/%u } postmaster_address = postmaster(a)mini.mmpcrofton.com protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { extra_groups = _keytabusers idle_kill = 15 mins unix_listener auth-userdb { user = _dovecot } } service dns_client { unix_listener dns-client { mode = 0600 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 } service imap { client_limit = 5 process_limit = 200 service_count = 0 } service lmtp { unix_listener lmtp { mode = 0600 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { client_limit = 5 process_limit = 200 service_count = 0 } service quota-exceeded { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-exceeded.sh unix_listener quota-exceeded { group = mail mode = 0660 user = _dovecot } user = _dovecot } service quota-warning { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-warning.sh unix_listener quota-warning { group = mail mode = 0660 user = _dovecot } user = _dovecot } ssl_ca = </etc/certificates/*.chain.pem ssl_cert = </etc/certificates/*.cert.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL:!ADH:!eNULL ssl_key = </etc/certificates/*.key.pem ssl_key_path = /etc/certificates/*.key.pem syslog_facility = local6 userdb { args = partition=/Library/Server/Mail/Config/dovecot/partition_map.conf enforce_quotas=no driver = od } verbose_proctitle = yes protocol lmtp { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol lda { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol imap { imap_id_log = * imap_id_send = "name" * "version" * mail_max_userip_connections = 20 mail_plugins = quota zlib fts fts_sk imap_quota imap_zlib imap_fts urlauth } protocol pop3 { mail_max_userip_connections = 6 }

[Dovecot] Problem with mail_location and INDEX location
by Matt Jones 29 Nov '12

29 Nov '12

HI, I'm pulling my hair out a little trying to get dovecot to save it's index locally rather than in the NFS mount. No matter what I do it seems to save the indices in the Maildir on the NFS. I'm using dovecot 2.0.18 on CentOS 6.3. The relevant config I'm using: mmap_disable = no dotlock_use_excl = no # only needed with NFSv2, NFSv3+ supports O_EXCL and it's faster mail_fsync = always mail_nfs_storage = yes mail_nfs_index = no lock_method = dotlock # Mail location and mailbox format. mail_location = maildir:/%Lh/Maildir/:INDEX=/var/indexes/%Ld/%Lu/ Dovecot runs under the user:group vmail:vmail, and the user has write access to those directories.

[Dovecot] Shutting down my Dovecot server?
by Bjørn T Johansen 29 Nov '12

29 Nov '12

I am planning to shut down my own Dovecot server and start using the other Dovecot server I am administering together with a friend.. And I was thinking that I don't want to copy the emails I have on my server so I want to start from scratch on the other server.. But I would like to be able to look at the old emails if I need to, so was wondering if there is a way to do this without using an imap server? Can I convert my mails stored in the maildir format to mbox or is there a better way to solve my problem?

[Dovecot] shared mailboxes and indexes
by Angel L. Mateo 28 Nov '12

28 Nov '12

Hello, We are deploying shared mailboxes in our mail system. We are running 2.1.9 and mail backend is maildir. As described at http://wiki.dovecot.org/SharedMailboxes/Shared when shared namespace is configured as namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } each user accessing this folder has its own index, stored in ~/Maildir/shared/%%u/<shared mailbox>, hasn't it? Our mail is store in NFS disks so we are very concerned about indexes optimizations (we had performance problems until we got all of our indexes and nfs tunned). So, is there any way so those indexes could be shared for all users (and they always would be updated). Regarding this... if we'd use dbox instead of maildir, indexes are a really important part of the mailbox and they can't be re-constructed when they are outdated. So, how do shared mailboxes work with dbox backend? Do I have to configure indexes in any particular way? -- Angel L.

[Dovecot] problems with quota and clients
by Marco Sacchetto 28 Nov '12

28 Nov '12

Hi, I had configured dovecot in a pretty standard way and had it working nicely enough with maildir quotas (no tests done apart for reaching the quota and looking at mails coming back). Still I wanted to have the quota and the actual quota usage displayed in postfixadmin (3.5) but I think I messed with something. Now I can connect to the mailbox, send mail, receive mail, see the quota usage in postfixadmin but: * thunderbird: can create a subfolder if i do so by hand from the client. But if I try sending a mail i get a [TRYCREATE] mailbox error as it seems that thunderbird can't create the Sent box anymore by its own; * thunderbird: when i delete mail, it goes in the trash folder. I try then to delete it from there. In thunderbird indeed I see no mail anymore but the quota level remain the same. Then I try to browser the mail directory and... yep, all the messages are still there! How come? This is the output of dovecot -n and the relevant sql configuration : # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-33-generic i686 Ubuntu 12.04.1 LTS ext4 auth_mechanisms = plain login auth_realms = yyyyyyyyy.it aaaaaaa.com xxxxx.it auth_verbose_passwords = plain debug_log_path = syslog dict { quotadict = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_uid = 150 info_log_path = /var/log/syslog last_valid_uid = 150 listen = * mail_debug = yes mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = " quota" mail_uid = vmail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size quota = dict:User quota::proxy::sqlquota quota_rule = *:storage=50M quota_rule2 = Trash:storage=+10M } postmaster_address = xxxxxxxx(a)yyyyyyyyy.it protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0660 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = quota } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } >>grep -v '^ *$#.*$\?$' dovecot-dict-sql.conf.ext connect = host=127.0.0.1 dbname=mail user=mail password=xxxxxxx map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } >>grep -v '^ *$#.*$\?$' dovecot-sql.conf.ext driver = mysql connect = host=localhost dbname=mail user=mail password=xxxxxxx default_pass_scheme = MD5-CRYPT password_query = \ SELECT username as user, password, '/var/vmail/%d/%u' as userdb_home, \ 'maildir:/var/vmail/%d/%u' as userdb_mail, 150 as userdb_uid, 8 as userdb_gid \ FROM mailbox WHERE username = '%u' AND active = '1' user_query = \ SELECT '/var/vmail/%d/%u' as home, 'maildir:/var/vmail/%d/%u' as mail, \ 150 AS uid, 8 AS gid, CONCAT('*:storage=',ROUND(mailbox.quota / 1024)) AS quota_rule \ FROM mailbox WHERE username = '%u' AND active = '1' iterate_query = SELECT username AS user FROM mailbox -- -- Questo messaggio è di carattere riservato ed è indirizzato esclusivamente al destinatario specificato.

[Dovecot] Any chance to access read-only mdboxes?
by Jost Krieger 28 Nov '12

28 Nov '12

We would like to provide a self-service restore function to our users using their IMAP client of choice.. Our idea was to use a snapshot (under ZFS, btrfs, whatever) and have it available to the user in a namespace. Unfortunately, but understandably, dovecot doesn't like the mdbox structure to be read-only. Is there any chance to change that? In the meantime, we could use a read-write snapshot, but we wouldn't like the users to really do changes to that snapshot. Our next attempt is to use ACLs, but it's a bit hard to gt the ACLs to the correct place in the snapshots, at least for thousands of users. Our currents solution (in test) is a quick and dirty patch to introduce inheritance to the ACLs by walking up the directory tree, so we need only one ACL. A cleaner solution would be very much appreciated. Yours Jost Krieger -- | Helft Spam ausrotten!

[Dovecot] Dovecot sieve with postfix.
by /#!/JoePea 28 Nov '12

28 Nov '12

Hi all, I can't get dovecot working with postfix. If I leave virtual_transport set to "virtual", I can send and receive messages just fine in roundcube. If I set virtual_transport to "dovecot", I can only send messages in roundcube, but incoming messages never arrive. Seems I can't get dovecot-lda to work. I need dovecot-lda in order for sieve filters to work. Any idea what I'm doing wrong? Here's `doveconf -n`: http://pastie.org/5401133 `postconf -n`: http://pastie.org/5401157 and `postconf -M`: http://pastie.org/5401177 Note: All I have to do is change virtual_transport = dovecot to virtual_transport = virtual and all will be fine, except for that I won't have sieve filtering which is what I really want. */#!/*JoePea

[Dovecot] IMAP over SSL
by petsy12＠lavabit.com 27 Nov '12

27 Nov '12

Hello. I've never tried Dovecot. Here is my attempt to enable IMAP over SSL on port 993. (BTW, I don't want to use port 143 at all.) # dovecot -n log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: *:143,[::]:143 ssl_listen: *:993,[::]:993 ssl: required ssl_cert_file: /etc/dovecot/keycert.pem ssl_key_file: /etc/dovecot/keycert.pem ssl_cipher_list: TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!NULL:@STRENGTH login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock auth default: passdb: driver: pam userdb: driver: passwd 1. Here is a snippet from dovecot.conf. Is it correct? Should I change something? (Note that I don't want to enable IMAP on port 143.) protocols = imaps protocol imap { listen = *:143,[::]:143 ssl_listen = *:993,[::]:993 } disable_plaintext_auth = yes ssl_listen = *:993,[::]:933 ssl = required ssl_cert_file = /etc/dovecot/keycert.pem ssl_key_file = /etc/dovecot/keycert.pem ssl_cipher_list = TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!NULL:@STRENGTH 2. I don't understand the syntax connected with auth. What auth options are enabled by default? dovecot.conf: No sections (e.g. namespace {}) or plugin settings are added by default, they're listed only as examples. Does it mean that passdb pam will use defaults (e.g. session=yes, setrcred=yes)? passdb pam { # [session=yes] [setcred=yes] [failure_show_msg=yes] [max_requests=<n>] # [cache_key=<key>] [<service name>] # # session=yes makes Dovecot open and immediately close PAM session. Some # PAM plugins need this to work, such as pam_mkhomedir. # # setcred=yes makes Dovecot establish PAM credentials if some PAM plugins # need that. They aren't ever deleted though, so this isn't enabled by # default. # # max_requests specifies how many PAM lookups to do in one process before # recreating the process. The default is 100, because many PAM plugins # leak memory. # # cache_key can be used to enable authentication caching for PAM # (auth_cache_size also needs to be set). It isn't enabled by default # because PAM modules can do all kinds of checks besides checking password, # such as checking IP address. Dovecot can't know about these checks # without some help. cache_key is simply a list of variables (see # /usr/share/doc/dovecot-common/wiki/Variables.txt) which must match # for the cached data to be used. # Here are some examples: # %u - Username must match. Probably sufficient for most uses. # %u%r - Username and remote IP address must match. # %u%s - Username and service (ie. IMAP, POP3) must match. # # The service name can contain variables, for example %Ls expands to # pop3 or imap. # # Some examples: # args = session=yes %Ls # args = cache_key=%u dovecot #args = dovecot } 3. Here is the output of `openssl s_client -tls1 -connect mail.example.com:993`. Is it OK? [snip] New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: zlib compression Expansion: zlib compression [snip] Verify return code: 18 (self signed certificate) --- * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. Also, where can I read about these options? Any comments are appreciated.

[Dovecot] Default fallback behaviour
by Nikita Koshikov 27 Nov '12

27 Nov '12

Hello list, Here is the problem: I have few: passdb { #1 } passdb { #2 } And relative userdb sections. If user not found in 1) section it fallbacks to next one - it's expected and right, IMHO. But when the user exists in both section and password verification fails on 1) database it successfully authenticated on next one. I think this behaviour should be configured. The main goal of 1) section for this server is to overwrite users in main (section2) database. Maybe I missed something and this option is already in dovecot code and I can't find it ? Or if not - will it be added in the future ? Dovecot version 2.1.10.
