Hi, I know it's a while since you've had this issue, but still do you remember by any chance how you solved this? I'm having the same problems, when all the directories are created with 700 and I need a group permissions to be at least 750. Thanks! regards,

[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instead of maildir, indexes are a really important part of the mailbox and they can't be re-constructed when they are outdated.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.

[Dovecot] lmtp_rcpt_check_quota working somewhere?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm running Dovecot v2.1 and enabled the lmtp_rcpt_check_quota option in conf.d/20-lmtp.conf, because I just found it in the sample config.

Many messages been continously delivered to this mailbox on this installation since May 2012, and the mdbox was only accessed with deliver and imap/pop3 from dovecot. About four hours after the problem initially appeared, I did a hard reset of the system because it was unresponsive. The error message is exactly the same before and after the hard reset. The problem is triggered by both IMAP access and dovecot deliver access. The whole mdbox is 6.6 GiB large and I guess that it contains about 300k-600k messages. It's an archive of public mailing lists, so I could give access to the files. Can anybody say something about this? May the mdbox be repaired?

[Dovecot] Dovecot IMAP/POP3 auto creating maildir
by Dominic Malolepszy 27 Nov '12

27 Nov '12

Hi I have observed that after deleting a mailbox and removing the user from the userdb, immediately accessing the mail account via POP3/IMAP causes Dovecot to auto create an empty mailbox, because the userdb/passdb details are still cached for 10minutes. Is there any option to tell Dovecot POP3/IMAP not to auto create the mailbox if it does not exist? Alternatively and less desirably is there a mechanism for telling Dovecot to expire a userdb/passdb cached entry? Running Dovecot 2.1.9 Dominic

[Dovecot] memory allocation issues
by Kelsey Cummings 27 Nov '12

27 Nov '12

One of our dovecot backend servers ran into a problem with it's auth process a few days ago. This doesn't appear to be the error logged when dovecot hits its internal limit so I'm not sure what is going on here. auth: Error: malloc: 58012: Cannot allocate memory auth: Error: Unable to allocate memory for mutexes from the region auth: Error: PANIC: Cannot allocate memory auth: passwd(test,1.1.1.1,<8HTlNHzNIQBAjhKC>): unknown user pop3: Error: Authenticated user not found from userdb, auth lookup +id=2509111297 (client-pid=4781 client-id=1) pop3-login: Internal login failure (pid=4781 id=1) (internal failure, 1 +succesful auths): user=<test>... There was at least 10+GB free RAM on the server and no indication of a system level issue at the same time. The server is running 2.1.9. There were about 3,200 active sessions, with something like 12 new sessions/sec. The other identical servers are/were handling virtually identical load with the same service uptime and haven't had any issues so far.

[Dovecot] fs_flush_file_handle_cache_dir: rmdir(/var/mail) AGAIN
by Ken Mandelberg 27 Nov '12

27 Nov '12

We are running Dovecot 2.0.12. It runs on only one server and /var/mail is local where all the INBOX's are stored. Users other IMAP folders are NFS mounted on the server. We see frequent Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy I know this error message has been around a long time. Should we still be seeing it on 2.0.12 with a local /var/mail. Perhaps the message is misleading and really complaining about folders other than INBOX that are NFS mounted. Our config has dovecot.conf:mail_nfs_index = no dovecot.conf:mail_nfs_storage = yes is that correct given the above? Also, does the flush error messages have any real consequences? My understanding is that the rmdir is meant to fail, just to force a flush.

[Dovecot] Filesystem quotas
by Andreas Kasenides 27 Nov '12

27 Nov '12

I could not determine if when using filesystem quotas (http://wiki2.dovecot.org/Quota/FS) Dovecot will use the reported quota and limits without the need of configuring them via "quota_rules". Is this possible somehow? Such a feature would determine the quota limits automatically from the filesystem quotas thereby allowing to make use of them in quota warnings. Dovecot already knows the quota settings and limits. Here is evidence from the logs > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: box=/Mail/ank > mount=/newmail match=yes > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: quota-fs: > host=xxxx.xxxx.ucy.xx.cy, path=/mail, uid=211, bytes > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: quota-fs: uid=211, > value=2779115520, limit=8388608000 I am using (testing) version 2.2alpha1.

[Dovecot] Plugin help, number of messages in mailbox
by Richard Platel 27 Nov '12

27 Nov '12

Hi, We use Dovecot for IMAP and POP (but not LDA), we want to do something when a user has an INBOX that becomes empty, or becomes not empty (set a flag in memcached, but that's not really important). I'm writing a plugin (for Dovecot 2.1.7). On mailbox_open() I can use mailbox_get_status() to get a count of messages in the mailbox, and then decrement this in expunge() or increment it in mailbox save_finish() (for IMAP APPEND or COPY commands). However in expunge() and mailbox_save_finish, even after calling the super function, mailbox_get_status doesn't update the number of messages in the mailbox. This is a problem if (for example) there are concurrent POP sessions. Two POP sessions could get all the messages in INBOX, one could logout, calling expunge a few times, eventually causing my plugin to note that the inbox is empty, then our LDA could deliver a message, mark the INBOX not empty, then the other POP session could log out, call expunge and cause my plugin to mark the INBOX empty, when it's not. So in summation: how can a plugin be notified of changes to a mailbox, and then accurately get the real number of messages in that mailbox?

[Dovecot] Folder layout after Cyrus to Dovecot migration
by Keith Edmunds 27 Nov '12

27 Nov '12

# dovecot --version 1.2.15 We're trying to migrate a server from Cyrus to Dovecot, and we're mostly there. On Cyrus, the folder layout in the MUA is: INBOX subfolder subfolder ... Sent Drafts Queue Trash Users cannot create sibling folders to the Inbox, only subfolders (and sub-subfolders, etc). We've replicated that with: -------------------------------------------------------------------------------- mail_location = maildir:/shared/imapmail/users/%u:INBOX=/shared/imapmail/users/%u:LAYOUT=fs namespace private { separator = / prefix = "INBOX/" inbox = yes } -------------------------------------------------------------------------------- ...however, the Sent/Drafts/Queue/Trash folders are now subfolders of Inbox. Cyrus seems to default to the above layout (at least, I can't find anywhere that defines it). There are no special settings in the MUA to achieve the abovev. Is there a way of replicating the above within Dovecot? We can probably go to V2 if we have to, but 1.2.15 would be preferable. Thanks, Keith

[Dovecot] cannot update mailbox - unable to lock for exclusive access
by 1st WebDesigns 27 Nov '12

27 Nov '12

Hi there, We're using Dovecot version 1.0.7 and Postfix, and since upgrading our Linux box we're getting this in the maillog: Nov 8 07:49:11 server1 postfix/local[27901]: 04B8E7081DA: to=<xyz(a)xyz.com>, orig_to=<abc(a)abc.com>, relay=local, delay=19, delays=0.07/0/0/19, dsn=4.2.0, status=deferred (cannot update mailbox /var/spool/mail/abc for user abc. unable to lock for exclusive access: Resource temporarily unavailable) Postfix is currently set to: mailbox_delivery_lock = fcntl, dotlock Dovecot has this: mbox_read_locks = fcntl mbox_write_locks = fcntl dotlock I've scoured the web and tried all kinds of different locking mechanisms and combinations to no avail. The mail is eventually delivered but on a busy day this can take several hours. In the evening it generally doesn't happen, which leads me to believe it occurs during the day when people have their mail clients open. However, this particular issue doesn't affect every user that has their mail client open, only some! We currently have the mailboxes in mbox format - yes I know we should upgrade to maildir which we will eventually, however we've been using mbox for the last 10 years and this has only become an issue since upgrading. What I have discovered this morning is a Dovecot connection that is open for 6 minutes before disconnection. During this 6 minutes the above problem occurs (new mail cannot get an exclusive lock). The same user will have connected and disconnected several times before and after, with a connection taking no more than a few seconds. But it seems sometimes the connection is taking longer than it should and I suspect the problem lies here. Please can anyone help! Thank you, G

[Dovecot] IMAP proxy - can it detect parodying to itself?
by Graham Leggett 26 Nov '12

26 Nov '12

Hi all, I have some IMAP servers fronted with separate perdition processes, and it would be ideal if I could collapse this down to having dovecot do both the IMAP proxying and the IMAP serving at the same time on the same IP addresses. One of the fields in my LDAP entries contains the canonical name of the server that hosts their mailbox, and if I follow the manual at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields#LDAP I could add the host field to enable proxying. My question is whether dovecot has the ability to notice whether dovecot is being asked to proxy to itself, in other words the value of "host" is the current dovecot server, and when this happens, ignore the proxy and just be a straight IMAP server, because the user has connected to the right box already. Is this possible? Regards, Graham --

Re: [Dovecot] doveadm fails with passdb authentication binds (dovecot 2.0.16)
by mailing lists 26 Nov '12

26 Nov '12

Hello, >> # doveadm mailbox list -u user001 >> doveadm(user001): Error: user user001: Auth PASS lookup failed >> doveadm(user001): Fatal: passdb lookup failed > Are you running this on a Dovecot proxy? It looks like doveadm wants to do a passdb lookup to find out which server should handle this user. Passdb lookups don't work with LDAP binding. But if everything else works then I think you simply shouldn't have enabled doveadm proxying. So, set doveadm_proxy_port back to 0? thank you Timo, setting doveadm_proxy_port to 0 did the trick.

[Dovecot] Missing Messages on IOS device
by David Morsberger 26 Nov '12

26 Nov '12

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] sieve-extprograms strips Return-Path headers
by Ben Morrow 25 Nov '12

25 Nov '12

The sieve-extprograms extension strips Return-Path headers before passing mail off to the external program. The patch to remove this behavious is trivial (and attached), but since it appears to be deliberate I felt I should investigate further. I believe this is basically a cut-and-paste error. The code to strip Return-Path has been there since the sieve-pipe plugin for Dovecot 1.x, and I believe it was copied from the equivalent code in the 'redirect' action for passing mail off to sendmail(8). In that case, stripping Return-Path is correct, since the message is being resubmitted for delivery (by SMTP or otherwise), and the last step of the new delivery will (should) add a new Return-Path header with the new envelope information. In the case of sieve-extprograms, though, the filtering is happening post-delivery, so a stripped Return-Path will never be replaced. Ben

[Dovecot] Proxy to join two accounts
by Tomek 23 Nov '12

23 Nov '12

Hello, I have server with IMAP on dovecot for user mails and second server on archiveopteryx as mail archive. I'm wondering if it's possible to make some sort of proxy to these two servers in way where: - dovecot server will be main IMAP service with INBOX, etc - I want archiveopteryx account to be something like shared folder with read only access (no delete, no move, etc) in path ex. /archive/user.name - this proxy mappings should allow adding few archive accounts to one user (in case of people replacement) + it will be cool if this mappings could be defined in database so I could write tools to manage archive access for bosses. Is such case possible to achieve with dovecot (any howto or example would be very helpful)? If not - do you know any proxy tools that could allow such configuration? Thanks for any help. Regards, Tomek.

[Dovecot] v2.1.10: Director director_servers order issue

Hi, I'm setting up an IMAP/POP cluster using dovecot director for some NFS reasons and I'm getting some troubles with director_servers directive. Configuration is shared on both nodes : director_servers = 10.0.50.50 10.0.50.51 director_mail_servers = 192.168.0.150 192.168.0.151 director_user_expire = 15 min service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } unix_listener director-userdb { mode = 0600 } inet_listener { port = 9090 } } service ipc { unix_listener ipc { user = $default_login_user } } Here 10.0.50.50 is node1, 10.0.50.51 is node2 # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never self is the same on both nodes, and that generate some cases that can be observed on logs : # logs on node1 dovecot: director: Error: Remote director thinks it's someone else (connected to 10.0.50.51:9090, remote says it's 10.0.50.50:9090) And this is true, TCP packet contain bad DATA : # tcpdump -i eth0 -nn src host 10.0.50.51 and port 9090 -s 0 -w - -l | strings | egrep '^ME' ME 10.0.50.50 9090 # logs on node2 dovecot: director: Error: connect(10.0.50.51:9090) failed: Invalid argument Invalid argument is present as bind() is not done with the appropriate IP : # strace -p 6063 -fF -s 1024 -e trace=bind,connect bind(28, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("10.0.50.50")}, 16) = 0 connect(28, {sa_family=AF_INET, sin_port=htons(9090), sin_addr=inet_addr("10.0.50.51")}, 16) = -1 EINVAL (Invalid argument) Also, during this time, CPU is ~100% used. bind() is done with node1 IP address. I also tested using a DNS : director_servers = director-all director-all is two A entries, first containing 10.0.50.50, second 10.0.50.51 and the result here is exactly the same. Using two configurations : # director_servers on node1 director_servers = 10.0.50.50 10.0.50.51 # director_servers on node2 director_servers = 10.0.50.51 10.0.50.50 Give the same result as showed before : # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never It seems that first sorted entry in director_servers is considered as "self". I'm using dovecot 2.1.10-0~auto+55 debian package from rename-it repository. Thanks for your help. -- Beber

[Dovecot] doveadm fails with passdb authentication binds (dovecot 2.0.16)
by mailing lists 23 Nov '12

Hello, I'm testing passdb auth binds with dovecot 2.0.16, but for some reason dovedm fails to work with the configuration showed below. The network trace shows the successful bind for the administrative user (uid=mailapp), but nothing for the mail user (uid=user001). what am i missing here? # doveadm mailbox list -u user001 doveadm(user001): Error: user user001: Auth PASS lookup failed doveadm(user001): Fatal: passdb lookup failed 10-auth.conf: ==================== disable_plaintext_auth = no auth_cache_size = 0 auth_cache_ttl = 0 auth_cache_negative_ttl = 0 auth_mechanisms = plain !include auth-ldap.conf.ext auth-ldap.conf.ext: ===================================== passdb { driver = ldap args = /etc/dovecot/passdb-dovecot-ldap.conf.ext } userdb { driver = ldap args = /etc/dovecot/userdb-dovecot-ldap.conf.ext } passdb-dovecot-ldap.conf.ext: ===================================== uris = ldap://ldap.example.com dn = uid=mailapp,ou=People,dc=example,dc=com dnpass = xxxxxxxxxx sasl_bind = no tls = no auth_bind = yes ldap_version = 3 base = dc=example,dc=com deref = never scope = subtree pass_attrs = uid=user pass_filter = (uid=%n) userdb-dovecot-ldap.conf.ext: ==================================== uris = ldap://ldap.example.com dn = uid=mailapp,ou=People,dc=example,dc=com dnpass = xxxxxxxxxx sasl_bind = no tls = no auth_bind = yes ldap_version = 3 base = dc=example,dc=com deref = never scope = subtree user_attrs = mailbox=mail=maildir:/var/maildir/%$,homeFilter=home,mailQuota=quota_rule=*:bytes=%$ user_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = uid=user,userPassword=password,\ mailbox=userdb_mail=maildir:/var/maildir/%$,homeFilter=userdb_home,mailQuota=userdb_quota_rule=*:bytes=%$ pass_filter = (&(objectClass=posixAccount)(uid=%n)) iterate_attrs = uid=user iterate_filter = (objectClass=posixMailAccount)

[Dovecot] whoson plugin for 2.0
by Chuck Cochems 23 Nov '12

23 Nov '12

I have found a plugin at ftp://ftp.ufanet.ru/pub/boco/dovecot/whoson-plugin/ I was able to make it function on a dovecot 1.2.8 server, by changing __attr_unused__ to ATTR_UNUSED and strlcpy to i_strocpy (since glibc doesn't HAVE strlcpy, on purpose). However, it doesn't work with 2.1 this is, of course, because getenv() no longer functions lie it used to in plugins. so i need a replacement for getenv("IP") and getenv("USER") to make this work. i know, pop before SMTP is stupid, but the isp i'm doing this for hs customers that have used pop before smtp for ages. so I MUST make a whoson plugin. as i said, the remote ip and the email address are required to interface with whoson. (this is superior to DRAC, which just opens the IP)

[Dovecot] User iteration with static userdb

Hi all, can someone explain me, please, why user iteration (iterate_query) doesn't work with static userdb? There isn't reason why it shouldn't work. In my opinion. However static userdb doesn't mean that user list not exist. Thanks Radek

[Dovecot] Is there a hook for a plugin to do some transient operation on the mail body ...
by Jay 23 Nov '12

23 Nov '12

... when the MUA has issued a FETCH? I am a Dovecot newbie ... so please bear with me if this is obvious. Basically what I am trying to do is process the mail body (in my own specific way) before Dovecot serves it up to the MUA. I want to do it as a transient operation in memory. So think of the scenario as ... - the MUA issues a FETCH - Dovecot intercepts the FETCH - Dovecot internally gets the mail from the storage into a buffer in memory ----> This is where I'd like to apply a function to the mail body and modify the mail body in the buffer (not in the storage) - Dovecot serves up the (modified) mail to the MUA Looking for a hook that allows me to do it using a plugin. Looks like the zlib plugin does something similar ... applies a decompression function ... but I am not 100% sure. Thanks for your help. -- J.

[Dovecot] maildir and end-of-line encoding
by Christoph Anton Mitterer 23 Nov '12

23 Nov '12

Hi. I just wondered, the following: My MDA may get mails that use LF or CR/LF end of line encodings and deliver them into maildirs. I couldn't find any information about, whether one should or must convert all into one format, cause AFAIK at least on the IMAP side, CR/LF is always used? How does this work on the maildir/backend side of dovcot? Can it work with both and simply automatically convert LF into CR/LF? Thanks, Chris.

Thank you. One thing that still doesn't work is subscribing to all mailboxes via "*", I guess because the folder names start with "." but dovecot mailbbox subscribe wants it without a starting "." Any clues how that can be solved? Regards Andre

[Dovecot] v2.1 memory usage
by Timo Sirainen 21 Nov '12

21 Nov '12

v2.1's imap/pop3 processes are linked with OpenSSL by default, because of imapc/pop3c storages. I wonder if you notice any actual (system-global) memory usage reduction when compiling without those and you have thousands of imap processes? ./configure --with-storages=mdbox sdbox maildir mbox cydir I guess I could try it myself also but maybe someone else wanting to reduce memory usage is quicker? :) Related to that, you can look at where imap processes' memory goes with: http://dovecot.org/tools/linux-maps-parse-imap.pl I don't know how much memory those (writable!) file-backed memory areas actually use per-process. Maybe nothing, maybe something..

[Dovecot] users mail folders have to be subscribed
by Andre Bischof 20 Nov '12

20 Nov '12

Hi, I did a migration from cyrus 2.2 to dovecot (fresh installation, details below) via cyrus2dovecot from FU Berlin. That worked, but I first was missing mails in subfolders ander Inbox. No I detected that they are in the users Maildir in folders in his directory. They are listed when using telnet: * LIST (\HasChildren) "." "INBOX.ebay" * LIST (\HasNoChildren) "." "INBOX.ebay.xj" But they are not shown in thunderbird, I have to subscribe to them one by one. I probably did something wrong and maybe messed up with namespace and seperator settings - it would be great if one could lead me out of that. The wiki was a great help installing and configuring everything, but now I'm stuck. I use dovecot 2.1.7 under Ubuntu 12.10: # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-18-generic x86_64 Ubuntu 12.10 auth_verbose = yes mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation s ubaddress comparator-i;ascii-numeric relational regex imap4flags copy include variab les body enotify environment mailbox date ihave namespace inbox { inbox = yes list = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@localhost protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } Any help is greatly appreciated!

Is there a way to synchronize dovecote mail store with another mail store, like zarafa, via imap or pop3? Thanks in advance
