pigeonhole + spamprobe
by Mark Constable 11 Jan '17

11 Jan '17

Would anyone have an example of how to use dovecot-pigeonhole to call spamprobe as an external program in the current 2.2.25?

Dovecot and MariaDB/MySQL
by Michael A. Peters 11 Jan '17

11 Jan '17

Howdy - For most of my dovecot servers, they are small and I just use unix accounts. However I am going to be running a new server for more general users, webmail (probably roundcube but I'm hacking roundcube quite a bit, enough that I'm calling it squarepeg instead so users familiar with roundcube will know it is quite different) and it will use MariaDB for account management. I already have it working, following the instructions at https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-my… - those instructions also work in CentOS 7 with the latest Dovecot - but there is something that really bothers me. It makes no provision for salting the password before the crypt function. What I would like to do is when creating a new account, use /dev/urandom to generate a random salt for the account that is stuck in the database along with the account and used when validating the password. That way in the event of a SQL injection attack that dumps the database - yes it is still bad, but 20 accounts that have the same password will have radically different hashes and thus won't be a clue that they are the same, the blackhat that gets the database dump would have to generate a rainbow table for each unique salt. I've looked at at least a dozen different Dovecot / MariaDB howto guides and none of the ones I have looked at supported any kind of individual salting of the user passwords. Can someone point me to a guide that does? I don't mind keeping the salt in the database, I just want to be able to have a different salt for each account. Thank you

GMail-like user labels in IMAP/dovecot, situation in 2017?
by Gioele Barabucci 11 Jan '17

11 Jan '17

Hello, I am in the process of updating my IMAP dovecot installation and I was wondering what is the current state of the art for GMail-like user-defined labels. Are GMail-like user-defined labels now somehow achievable with dovecot? If now, what is missing? Standardized metadata formats? Support in clients? I searched the web a bit but I could not find any activity in the relevant IETF working groups. That seems strange to me, because the user-defined labels looks like a feature many users would like to have. I suppose I haven't found the relevant discussion group. Is this kind of enhancement to IMAP being discussed somewhere? Regards, -- Gioele Barabucci <gioele(a)svario.it>

Poolmon: Problem with index-locking
by Tom Sommer 11 Jan '17

11 Jan '17

I have Poolmon (https://github.com/brandond/poolmon) set up. When it does all the checks concurrently, obviously there are locking issues on each mailserver it tests: "Warning: Locking transaction log file xxxx/indexes/dovecot.list.index.log took 60 seconds (syncing)" It's just an empty mailbox. Is there any way to do a login test, without locking the index files? Hence avoiding these warnings/errors? Thanks. -- Tom

doveadm output format changes
by Benoit Branciard 10 Jan '17

10 Jan '17

It appears that doveadm output format changes every now and then, without particular notice. For example, the following command: doveadm -f pager mailbox status 'messages recent' '*' did output something like this until v2.2.24 : mailbox: Mailbox1 messages: 58 recent: 12 ^L mailbox: Mailbox2 messages: 128 recent: 0 but switched to that in v2.2.26 : Mailbox1 messages: 58 recent: 12 ^L Mailbox2 messages: 128 recent: 0 This seems related to the following changelog entry: 2016-10-25 20:51:36 +0300 Timo Sirainen <timo.sirainen(a)dovecot.fi> (5baa99e) doveadm: "pager" formatter supports now DOVEADM_PRINT_HEADER_FLAG_HIDE_TITLE M src/doveadm/doveadm-print-pager.c Some other format changes did also occur in the past. For example, "doveadm user" had a specific format in v2.0.19 (and ignored the "-f format" option), and obviously defaulted to the "-f tab" format (which has different rendering) somewhere in the v2.2.x or 2.1.x. Such changes render maintenance of wrapping scripts particularly tedious. Could it be possible to avoid such breaking changes in the future ? -- Benoit BRANCIARD Service InfraStructures (SIS) Direction du Système d'Information et des Usages Numériques (DSIUN) Université Paris 1 Panthéon-Sorbonne Centre Pierre Mendès France 90 rue de Tolbiac - 75634 Paris cedex 13 - France Bur.

Virtual POP3 namespaces and quota-status
by Aurélien Beaujean 09 Jan '17

09 Jan '17

Hi, I've tried to do configure Virtual POP3 INBOX (dovecot version 2.2.18) as explained here http://wiki.dovecot.org/Plugins/Virtual with a static userdb and nopassword=y so I dont have any database on the dovecot server without the possibility to distinguish POP3 or IMAP in the userdb extra field to change the namespace on the fly. So I've put the namespace virtual informations inside the protocol pop3 { ... }, I did the same for the protocol imap { }: protocol pop3 { mail_plugins = $mail_plugins last_login virtual namespace inbox { prefix = separator = / list = yes } namespace virtual { inbox = yes prefix = virtual/ separator = / location = virtual:/etc/dovecot/virtual:INDEX=MEMORY list = no hidden = yes } namespace real { prefix = RealMails/ separator = / list = no hidden = yes } } protocol imap { mail_plugins = $mail_plugins imap_quota last_login namespace inbox { inbox = yes } } protocol lda { mail_plugins = " quota sieve" namespace inbox { inbox = yes } } passdb { args = nopassword=y uid=vmail gid=vmail home=/var/mail/%2Mn/%2.2Mn/%n driver = static } userdb { args = nopassword=y uid=vmail gid=vmail home=/var/mail/%2Mn/%2.2Mn/%n driver = static } service quota-status { executable = quota-status -p postfix inet_listener { port = 12340 } process_min_avail = 8 } But the service quota-status getting lost with a message: namespace configuration error: inbox=yes namespace missing I didn't find a way to tell quota-status which namespace to use as you can't setup a default one. If I declare a "global" namespace inbox pop3 deamon fails because of duplicated namespace inbox in the configuration files: pop3(xxx): Error: User initialization failed: namespace configuration error: There can be only one namespace with inbox=yes Any idea before I will patch some piece of code to disable the unique restriction of inbox namespace ?

dsync for subscription on public/shared folder
by Mike Fröhner 09 Jan '17

09 Jan '17

Hello, I already wrote regarding that, but maybe it sounded too complex. I will write it a bit softer now. The replication through dsnyc works perfectly with one exception. I am having an issue with the replication of the subscriptions file on shared folder. We have a public mailbox defined: namespace public-test { location = maildir:/opt/mail/_public/test prefix = public/test/ separator = / subscriptions = no type = public } There 2 subfolder .Test1 and .Test2 which I would like to subscribe on my user "ldaptestuser" which is part of the group "ldaptestgroup" The dovecot-acl file on /opt/mail/_public/test and /opt/mail/_public/test/.Test{1,2} are the same and are containing: group=ldaptestgroup lrwstipekxa Now if I login through my client (Thunderbird or Roundcubemail) I can see the following debug log: dovecot: imap(ldaptestuser): Debug: acl: acl username = ldaptestuser dovecot: imap(ldaptestuser): Debug: acl: owner = 0 dovecot: imap(ldaptestuser): Debug: acl: group added: domain users dovecot: imap(ldaptestuser): Debug: acl: group added: ldaptestgroup dovecot: imap(ldaptestuser): Debug: acl: group added: all_mailuser I created one new private folder on the mailbox of my test user and also subscribed it. This subscription is successfully replicated. After that I am trying to subscribe the public folder. I can see the folder in my client after I subscribed them. But on the 2nd dovecot server the subscription file is not updated. imap-1 # cat subscription Private1 public/test/Test1 imap-2 # cat subscription Private1 The debug log on both dovecot server tells me: dovecot: doveadm(<ip>,ldaptestuser): Debug: Effective uid=834603987, gid=991, home=/opt/mail/ldaptestuser dovecot: doveadm(<ip>,ldaptestuser): Debug: acl: No acl_shared_dict setting - shared mailbox listing is disabled dovecot: doveadm(<ip>,ldaptestuser): Debug: maildir++: root=/opt/mail/_public/test, index=, indexpvt=, control=, inbox=, alt= dovecot: doveadm(<ip>,ldaptestuser): Debug: acl: initializing backend with data: vfile dovecot: doveadm(<ip>,ldaptestuser): Debug: acl: acl username = ldaptestuser dovecot: doveadm(<ip>,ldaptestuser): Debug: acl: owner = 0 dovecot: doveadm(<ip>,ldaptestuser): Debug: acl vfile: Global ACLs disabled It looks like the doveadm() cannot find the group or is not checking/initalizing the groups. Anybody any idea if I missconfigured something or is this just a bug? I really would appreciate some help. kind regards, Mike;

Auth-policy: auth_policy_server_url and https support
by gregc＠olypensupport.com 08 Jan '17

08 Jan '17

When using Auth policy server it doesn’t currently doesn’t support https. In version 2.2.27: Policy server HTTP error: 9002 Couldn't initialize SSL context: Can't verify remote server certs without trusted CAs (ssl_client_ca_* settings) and in version 2.3.devel Policy server HTTP error: 9002 Requested https connection, but no SSL settings given dovecot.conf does have “ssl_client_ca_dir = /etc/ssl/certs” set. Looking around the source, http-client-settings are not given the ssl_ca_dir or ssl_ca_file setting from the config. Admittedly SSL tear up/down is little expensive per auth, but I think it maybe it should still work?

.dovecot.sieve location issue
by Jibeji 08 Jan '17

08 Jan '17

Hello, I am trying to set sieve up on a Centos 7 server. It's a configuration with postfix, Maildir, MySQL and virtual domains which works fine. I have created a simple .dovecot.sieve in the user's directory: # cat /home/mail/domain.com/user/.dovecot.sieve require "fileinto"; redirect "other_address(a)other_domain.com"; Here are the logs: dovecot: lda(user(a)domain.com): Debug: sieve: Pigeonhole version 0.4.2 initializing lda(user(a)domain.com): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts. dovecot: lda(user(a)domain.com): Debug: sieve: script file /home/mail/ domain.com/.dovecot.sieve not found dovecot: lda(user(a)domain.com): Debug: sieve: user's script ~/.dovecot.sieve doesn't exist (trying default script location instead) lda(user(a)domain.com): Debug: sieve: no default script configured for user lda(user(a)domain.com): Debug: sieve: user has no valid location for a personal script lda(user(a)domain.com): Debug: sieve: no scripts to execute: reverting to default delivery. dovecot: lda(user(a)domain.com): msgid=<005b01d269ca$f287ebf0$d797c3d0$@fr>: saved mail to INBOX It tells that user's script ~/.dovecot.sieve doesn't exis However, on the troubleshooting guide, I can see these logs: dovecot: lda(hendrik): Debug: sieve: using sieve path for user's script: /home/hendrik/.dovecot.sieve dovecot: lda(hendrik): Debug: sieve: opening script /home/hendrik/.dovecot.sieve As you can see, it refers to "lda(hendrik)" but not "lda(user(a)domain.com" I am wondering whether Sieve looks for the file elsewhere than /home/mail/ domain.com/user/.dovecot.sieve Do you have any idea?

Hello! I run dovecot for many years now, but today it ran into a bug I've never seen before. Searching the archives, this bug seems to occur very seldom. The current server installation & configuration is running since mid 2015, uptime of the server today is more than two months.

Dovecot dsync tcps sends incomplete certificate chain

Hi, I'm trying to configure a Dovecot dsync service between two servers, using a tcp+ssl connection and a valid Let's Encrypt certificate. I followed the guide on the wiki (http://wiki.dovecot.org/Replication) using the tcps method, but when I launch the replication it fails writing on the log (/var/log/mail.err): (Server 1 - sync "client" )| Error: sync: Disconnected from remote: Received invalid SSL certificate: unable to get local issuer certificate: /CN=mail.dividebyzero.it (Server 2 - sync "server")| Error: doveadm client disconnected before handshake: <no error> If I try to connect to the server using openssl s_client, on the port 993 (imaps) the server correctly sends the full chain: $ openssl s_client -connect server1.fqdn:993 CONNECTED(00000003) depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3 verify return:1 depth=1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3 verify return:1 depth=0 CN = mail.dividebyzero.it verify return:1 --- Certificate chain 0 s:/CN=mail.dividebyzero.it i:/C=US/O=Let's Encrypt/CN=Let's Encrypt Authority X3 1 s:/C=US/O=Let's Encrypt/CN=Let's Encrypt Authority X3 i:/O=Digital Signature Trust Co./CN=DST Root CA X3 ... while on the doveadm port it fails: $ openssl s_client -connect server1.fqdn:7557 CONNECTED(00000003) depth=0 CN = mail.dividebyzero.it verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 CN = mail.dividebyzero.it verify error:num=21:unable to verify the first certificate verify return:1 --- Certificate chain 0 s:/CN=mail.dividebyzero.it i:/C=US/O=Let's Encrypt/CN=Let's Encrypt Authority X3 ...

IMAP proxy for Exchange - encrypted backend Communication?
by tom 06 Jan '17

06 Jan '17

Hello, I try to setup a IMAP proxy for my old Exchange server. Running Dovecot v2.x on Centos 7. So far I follow http://wiki2.dovecot.org/HowTo/ImapcProxy and it seem to work. The only but major thing is with this setup - the communication between proxy and backend is not encrypted. :( To fix this, I changed the config and add: imapc_ssl=imaps imapc_port=993 but it doesnt work, because of verify failure of the self signed backend certificate: Jan 5 21:48:55 imap dovecot: imap(user1): Error: imapc(192.168.1.1:993): Couldn't initialize SSL context: Can't verify remote server certs without trusted CAs (ssl_client_ca_* settings) Jan 5 21:48:55 imap dovecot: imap(user1): Error: imapc(192.168.1.1:993): No SSL context Jan 5 21:48:55 imap dovecot: imap(user1): Error: imapc: Command failed: Disconnected from server Jan 5 21:48:55 imap dovecot: imap(user1): Error: user tkoenig: Initialization failed: Initializing mail storage from mail_location setting failed: Mailbox list driver imapc: Failed to access imapc backend Jan 5 21:48:55 imap dovecot: imap(user1): Error: Invalid user settings. Refer to server log for more information. I didnt found anything in the documentation which tells dovcot not verify the backend certificate. Is there a know way to get it runing? Many thanks for any hint! regrds, Tom

dovecot-pigeonhole running external script ends with signal 11
by Tobi 06 Jan '17

06 Jan '17

Hi, I'm running a dovecot 2.2.26 (self compiled) on a Centos 7. I have a sieve script which should run an external script (in filter mode) that encrypts the mail using the users pub key. I configured 90-plugin.conf as follows plugin { sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.filter sieve_filter_bin_dir = /etc/dovecot/sieve-filters sieve_filter_exec_timeout = 10000 } The script is named SCRIPT and is called in my sieve script require "vnd.dovecot.filter"; if blabla { filter "SCRIPT" ["me(a)example.com"]; } the script returns the encrypted mail. I can call this SCRIPT without any error manually on the console as dovecot user (vmail). Also sieve-test "says" that the script called sucessfully su vmail sieve-test -e -t - -Tlevel=commands -r me(a)example.com -l /home/vmail/example.com/me/.Maildir /home/vmail/example.com/me/.dovecot.sieve /tmp/test.mail ... 23: filter action 23: execute program `SCRIPT' 23: executed program successfully 23: changed message ... info: msgid=<B5OEuIEvrCZzcoJ7A6fCF-ka2Nwz-Ze2UCO840Panvw.w7zr1vruaJMbDBwK63natps3v__yOgbhHy3ntACTU0s@redacted>: stored mail into mailbox 'INBOX'. sieve-test(vmail): Info: final result: success and I get the encrpted message in my mailbox. Just when it's called upon delivery via lmtp the script ends with signal 11 Jan 3 15:59:48 mbox2 dovecot: lmtp(me(a)example.com): Error: program `/etc/dovecot/sieve-filters/SCRIPT' terminated abnormally, signal 11 And in ~/.dovecot.sieve.log I can find the following .dovecot: line 23: error: filter action: failed to execute to program `SCRIPT': refer to server log for more information. [2017-01-03 15:59:48]. I have no idea why the manual call runs perfect and the call from sieve file ends up in this error. Does anyone have an idea how I could narrow down the source of this error? Or even better how to fix it? :-) Thanks for any answer tobi

A public mailbox "Public/Spam-Learning" in a public namespace with per-user "Seen" flags is configured like this: namespace pub { hidden = no inbox = no list = children location = maildir:/var/vmail/public:INDEXPVT=~/Maildir/public prefix = Public/ separator = / subscriptions = no type = public mailbox "Spam-Learning" { auto = subscribe } } The log files are full of error messages like these (got about 15000 in the last three days): 2017-01-03T11:19:28.242386+01:00 mailserver01 dovecot: imap(foo.bar(a)example.org): Error: /var/vmail/example.org/foo.bar/Maildir/public/.Spam-Learning/dovecot.index.pvt reset, view is now inconsistent 2017-01-03T11:19:28.248524+01:00 mailserver01 dovecot: imap(foo.bar(a)example.org): Error: /var/vmail/example.org/foo.bar/Maildir/public/.Spam-Learning/dovecot.index.pvt view is inconsistent 2017-01-03T11:23:50.209732+01:00 mailserver01 dovecot: imap(baz.quux(a)example.org): Error: /var/vmail/example.org/baz.quux/Maildir/public/.Spam-Learning/dovecot.index.pvt reset, view is now inconsistent 2017-01-03T11:23:50.775940+01:00 mailserver01 dovecot: imap(some.user(a)example.org): Error: /var/vmail/example.org/some.user/Maildir/public/.Spam-Learning/dovecot.index.pvt reset, view is now inconsistent 2017-01-03T11:25:38.419536+01:00 mailserver01 dovecot: imap(other.user(a)example.org): Error: /var/vmail/example.org/other.user/Maildir/public/.Spam-Learning/dovecot.index.pvt reset, view is now inconsistent 2017-01-03T11:34:14.351346+01:00 mailserver01 dovecot: imap(more.user(a)example.org): Error: /var/vmail/example.org/more.user/Maildir/public/.Spam-Learning/dovecot.index.pvt reset, view is now inconsistent 2017-01-03T11:41:37.488916+01:00 mailserver01 dovecot: imap(support.user(a)example.org): Error: /var/vmail/example.org/support.user/Maildir/public/.Spam-Learning/dovecot.index.pvt reset, view is now inconsistent This problem did not seem to manifest itself in Dovecot 2.2.25, we see it only after upgrading to 2.2.27. I am not sure what the effects are. It seems that messages moved to the Public/Spam-Learning folder are deleted after a short while (not by the sa-learn cron job, which runs every morning) but I currently cannot say if this is because a user deletes them explicitly or because Dovecot does something it shouldn't. So this observation is possibly not relevant. It also doesn't seem to matter what kind of IMAP client access the Spam-Learning folder. Our users use Thunderbird, Apple Mail, Outlook, Roundcube, Horde and various mobile clients as well. I have attached the output of doveconf -n for reference. What could be the issue here? Are we doing something wrong or is this a bug in Dovecot? Thanks! Andreas

expunging all mailboxes
by Michael Fox 03 Jan '17

03 Jan '17

Evidently, the 'doveadm expunge' command requires a "mailbox" to be defined in the search string. But is there a way tell it all mailboxes for a user? For example, something like: doveadm expunge -u user@domain mailbox ALL savedbefore 30d Thanks, Michael

two listeners with different "driver = " configs
by mj 03 Jan '17

03 Jan '17

Hi, I would like to have two seperate imap listeners, with different authentication settings, but the mailstore and userbase etc will be identical. I know I can do this: > service imap-login { > inet_listener imap { > port = 143 > } > inet_listener imap2 { > port = 144 > } > } But I'm unsure how to configure imap/143 with "driver = ldap" and imap2/144 with "driver = pam" Just to explain why i would like this: I am using pam-script-saml (https://github.com/ck-ws/pam-script-saml) to enable saml-based access to dovecot. I would like to have one listener 144 to only serve this saml authentication listener, and the regular 143 listener with driver = ldap. Is that config possible? Best regards, MJ

differential SETACL silently fails if no vfile exists
by Vincent Breitmoser 02 Jan '17

02 Jan '17

In version 2.2.13, with `acl = vfile`, setting a differential ACL permission doesn't work if there are no permissions set yet. Example IMAP log: b1 GETACL test * ACL test valodim lrwstipekxacd b1 OK Getacl completed. b2 SETACL test valodim -l b2 OK Setacl complete. b3 GETACL test * ACL test valodim lrwstipekxacd b3 OK Getacl completed. My expectation was that the file would be created with default permissions, and the requested change then applied. However, no acl permission is set and no vfile is created for this mailbox in the process. This does work as expected (and a file is created) if I set a non-differential ACL first: b4 SETACL test valodim lrwstipekxacd b4 OK Setacl complete. b5 GETACL test * ACL test valodim akxeilprwtscd b5 OK Getacl completed. b6 SETACL test valodim -l b6 OK Setacl complete. b7 GETACL test * ACL test valodim akxeiprwtscd b7 OK Getacl completed. - V

I have compiled dovecot2 for FreeBSD with the tcpwrap option. A tcpwrap binary gets built and resides in the FreeBSD directory /usr/local/libexec/dovecot an examination of the compiled options (using the FreeBSD pkg install dovecot2) confirms: LIBWRAP : on yet, when I adjust dovecot.conf with: login_access_sockets = tcpwrap I get the following logged error message: 20161229 17:02:49 imap-login: Error: connect(tcpwrap) failed: No such file or directory Is there any way to turn up some super logging so that I can find just what dovecot feels is the failure ?

dovecot-ldap.conf.ext for FreeIPA usage
by Matt . 29 Dec '16

29 Dec '16

Hello, I'm figuring out how to auth users against FreeIPA and I wonder if someone did this without GSAPI. My users are stored in a mysql DB where I wonder what I shall use as authname, the username or the mailaddress. As the mailaddress is always unique it could be best but if a user has multiple mailaddresses under seperate domains username might be better. Any clue here and maybe an example for dovecot-ldap.conf.ext when using FreeIPA ? Thanks! Matt

IPv4/IPv6 mismatches of doveadm: Fatal: connect(fd00:b::1:12345) failed: Connection refused
by Michael Grimm 28 Dec '16

28 Dec '16

Hi — I recently extendend my IPsec tunnel between two mail servers to deal with IPv4 addresses in addition to IPv6 ones. (No specific reason for that.) I ran into an issue worth reporting. This is Dovecot v2.2.27 (c0f36b0) at FreeBSD STABLE-11. Previously: dovecot.conf: plugin { mail_replica = tcp:remote.test } service doveadm { inet_listener { address = [::] } } | local> host remote.test: remote.test has IPv6 address fd00:b::1 working well. Currently: dovecot.conf: plugin { mail_replica = tcp:remote.test } service doveadm { inet_listener { address = * } } | local> host remote.test: remote.test has address 10.2.0.1 remote.test has IPv6 address fd00:b::1 Now, Replication stops and throws an error like: | <mail.crit> local.test dovecot: doveadm(user): Fatal: connect(fd00:b::1:12345) failed: Connection refused If I either #) remove IPv6 from my lokal DNS, #) use "mail_replica = tcp:10.2.0.1", or #) define the appropriate IPv4 address of remote.test in /etc/hosts, then replication works as usual. Hmm, shouldn't doveadm be more persistent in using every IP address of that entry of mail_replica *before* throwing a "Fatal:" error? Or do I miss something, and it's a feature, instead? Regards, Michael

Identify if a message_part is an attachment ?
by Sai Kiran Gummaraj 27 Dec '16

27 Dec '16

Hello, This is my first post to this group. I have read through the instructions before posting. I hope am doing the right thing. If not my sincere apologies. I am in the process of developing a dovecot IMAP plugin (over v2.2.25). The plugin works with mdbox/sdbox which has ability to keep attachments as external references (via SiS POSIX). The plugin must enable fetching attachment from REDIS instead of local-store. To accomplish this I was following dovecot via my debugger. I wanted to understand if there was a way to determine a message_part to be of an attachment type ? Thanks. -- Regards, Sai Kiran cmd_fetch() |_ imap_fetch_more() |_ imap_fetch_more_int() |_ imap_fetch_state *state = &ctx->state; state->cur_mail is NULL. search mailbox |_ mailbox_search_next(state->search_ctx, &state->cur_mail) |_ mailbox_search_next_nonblock (via vfunc) |_ index_storage_search_next_nonblock |_ search_more_with_prefetching(ctx, mail_r) |_ mail = index_search_get_mail(ctx) |_ allocates mail (vfunc mail_alloc) and calls hook. |_ also allocates index_mails ret = search_more_with_mail(ctx, mail); |_ call handler (*h) => fetch_body_msgpart |_ imap_msgpart_open |_ imap_msgpart_find_part(mail, msgpart, &part); /* only mail comes here */ mail (uid=1739, seq=5) msgpart (section_number = 2, fetch_type = FETCH_MIME_BODY, partial_offset = 0, partial_size = 512, decode_cte_to_binary = 0) |_ mail_get_parts(mail, &parts) /* atmail send msgpart */ |_ call to p->v.get_parts(mail, parts_r) (index_mail_get_parts) /* atmail over-ride this function */ |_ get_cached_parts(mail) /* sets data->part */ |_ get_unserialized_parts(index_mail) |_ get_serialized_parts(mail, &part_buf) |_ index_mail_cache_lookup_field |_ mail_cache_lookup_field |_ imap_msgpart_open_normal() |_ .. see call stack below ..

postlogin script - still confused
by Michael Fox 26 Dec '16

26 Dec '16

> You need to use executable = script-login -- /path/post-login.sh -a -r -g > note the double-dash. it tells getopt to stop processing arguments. > > Aki OK. Thanks. So let me make sure I have this right, since there is no syntax defined on the wiki - just an example which doesn't show the above syntax. The valid possibilities are: executable = script-login [-d] /path/script1 /path/script2 ... -or- executable = script-login [-d] -- /path/script1 -a -r -g -s In other words, I can either call multiple scripts, each with no arguments, or I can call one script with arguments. But I cannot call multiple scripts, some with arguments, some without arguments. Is that correct? If not, please show all valid syntax options. Also, regarding the exec "$@" line shown at the end of the wiki examples. If I pass arguments "-a -r -g -s" to my script, as in: executable = script-login -- /path/script1 -a -r -g -s then doesn't the exec "$@" line at the end become: exec -a -r -g -s And surely that's not right. So, could you please explain in words the purpose of the exec line at the end - what it does, why it's needed, and what to do if I'm sending arguments to my postlogin script? Thanks, Michael

Domains on different IPs
by Mark Constable 23 Dec '16

23 Dec '16

I want to supply separate Letsencrypt certificates for each virtual domain and seeing that SNI does not work I need to allocate separate IPs. Could anyone give some pointers, or keywords to search for, on... a) how to make dovecot listen for different domains on different IPs? b) how to configure separate SSL certs for each of these IPs?

doveadm acl set negative rights not supported?
by Peter Benko 21 Dec '16

21 Dec '16

Hi all, I'm trying to set an ACL with negative rights. I have no problems setting it with standard IMAP commands, but I'm unable to do it with the doveadm acl command. I tried: sudo -u vmail doveadm acl set -u "user@domain" Spam user="-user@domain" lookup (notice the "-" before the username) Unfortunately, this adds a (positive) ACL for the user named "-user@domain" instead of adding a negative one for the user "user@domain". Am I messing up something or is negative ACL support missing from doveadm? I have not seen anything in the docs about this... Regards, Peter

Checking sieve
by Gerben Wierda 19 Dec '16

19 Dec '16

A simple question: I’ve installed roundcube on macOS Sierra with Server 5.2 and created a set of sieve rules in my dovecot setup. How can I check their functioning (other than send test mails) e.g. is there some logging I can set / look at? G

Upgrade from version 1 to 2
by Peter Fraser 19 Dec '16

19 Dec '16

Hi All I am upgrading from dovecot-1.2.17 to dovecot2-2.2.27_4. I configured version 2 from scratch. I have email in the maildir format. Would it be ok in theory if I simply copy over the email files from the version 1 server to the version 2 server or are there any hidden dangers here? Any problems with indexing? Thanks for any advice

Renumbering UID on messages
by Ricardo Branco 19 Dec '16

19 Dec '16

I am having a problem with Horde due to large variations in email UID for a few users. At one time they were receiving thousands of emails a day, they have deleted all these messages but because they still have early emails in the mailbox the UID range from start to now is massive. We use Horde webmail and it creates an internal array based on range of messages but due to large UID range it eats though the ram. If I use dsync on a mailbox will the UIDs be renumbered? -- The information contained in or attached to this email is intended only for the use of the individual or entity to which it is addressed.

RFC 3501 violation in FETCH BODY responses
by Guilhem Moulin 18 Dec '16

18 Dec '16

Hi there, Quoting RFC 3501 sec. 7.4.2 “FETCH Response” (data item BODYSTRUCTURE): “A body type of type MESSAGE and subtype RFC822 contains, immediately after the basic fields, the envelope structure, body structure, and size in text lines of the encapsulated message.” According the ABNF (RFC 3501 sec. 9) the envelope structure is that of the ENVELOPE FETCH data item, and the env-{from,sender,reply-to,to,cc, bcc} fields are non-space-separated address lists: body-type-msg = media-message SP body-fields SP envelope SP body SP body-fld-lines envelope = "(" env-from SP … SP env-to SP … ")" env-from = "(" 1*address ")" / nil env-to = "(" 1*address ")" / nil While this is indeed the case for ‘FETCH … (ENVELOPE)’, for ‘FETCH … (BODY)’ dovecot 2.2.25 adds a space between addresses of an address list of the envelope structure of an encapsulated MESSAGE/RFC822 message. See the attached patch to ‘src/lib-imap/test-imap-bodystructure.c’, which currently (2.2.25) fails as follows test-imap-bodystructure.c:122: Assert failed: strcmp(str_c(str), testmsg_body) == 0 test-imap-bodystructure.c:129: Assert failed: strcmp(str_c(str), testmsg_bodystructure) == 0 imap bodystructure parser ............................................ : FAILED because the ‘env-to’ field of the envelope structure of the encapsulated MESSAGE/RFC822 message is printed as ((NIL NIL "sub-to1" "domain.org") (NIL NIL "sub-to2" "domain.org")) while it should be ((NIL NIL "sub-to1" "domain.org")(NIL NIL "sub-to2" "domain.org")) After a quick look at the source, this seems to be due to src/lib-imap/imap-bodystructure.c:imap_write_list, which always separates list items with spaces. In the case of an envelope, only the top-level list should be space-separated. Indeed, not adding a space between items of type IMAP_ARG_LIST in the recursive call makes the test pass again. Cheers, -- Guilhem.

Error while migrating mailbox with 'doveadm sync'
by Zhang Huangbin 18 Dec '16

18 Dec '16

Dear all, I successfully migrated hundreds of mailboxes with Dovecot 2.2.24 on OpenBSD 6.0 (amd64. Old server is OpenBSD 5.1, i386, Dovecot-2.0.17), but got error while migrating 3 mailboxes: # doveadm -o mail_fsync=never sync -1 -R -s '' -u user(a)domain.com imapc: dsync(user(a)domain.com): Panic: file mailbox-alias-plugin.c: line 77 (mailbox_symlink_exists): assertion failed: (ret > 0) Abort trap Same error while running ‘doveadm … backup …'. What does this error actually mean? How can i fix it? - Here’s full log running doveadm with ‘-D’ option: http://pastebin.com/Um5fbuNM - ‘dovecot -n’ on old server: http://pastebin.com/4E6xzFKU - ‘dovecot -n’ on new server: http://pastebin.com/4uHwQnMN I checked release notes of Dovecot 2.2.25/26/27, there’re 3 fixes related to 'doveadm sync’, but not sure whether it helps fix this issue. 2.2.26: + doveadm sync/backup: Added -I <max size> parameter to skip too large mails. + doveadm sync/backup: Fixed -t parameter and added -e for "end date”. 2.2.27: - doveadm sync -1: Fixed handling mailbox GUID conflicts.

Antispam plugin: insufficent error messages
by Volker Wysk 18 Dec '16

18 Dec '16

Hi! "Dovecot always logs a detailed error message if something goes wrong. If it doesn't, it's considered a bug and will be fixed." (http:// wiki2.dovecot.org/Logging) I'm trying to set up a spam filter with dovecot-antispam and dspam as backend. When I move a spam message from INBOX to Spam, I get this in syslog: Nov 28 21:15:58 desktop imap: antispam: mailbox_is_unsure(Spam): 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_trash(INBOX): 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_trash(Spam): 0 Nov 28 21:15:58 desktop imap: antispam: mail copy: from trash: 0, to trash: 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_spam(INBOX): 0 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_spam(Spam): 1 Nov 28 21:15:58 desktop imap: antispam: mailbox_is_unsure(INBOX): 0 Nov 28 21:15:58 desktop imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 There are no log entries about how dspam is called, or what goes on. Indeed, dspam doesn't get called at all. I know, because I've examined the antispam- plugin source code. There would be a log message if dspam was called. It's hard to study the source code, because there are hardly any comments. I have been able to trace the problem to function signature_extract_to_list() in signature.c. There, -1 is returned: int signature_extract_to_list(const struct signature_config *cfg, struct mailbox_transaction_context *t, struct mail *mail, struct siglist **list, enum classification wanted) { const char *const *signatures; struct siglist *item; signatures = get_mail_headers(mail, cfg->signature_hdr); if (!signatures || !signatures[0]) { if (!cfg->signature_nosig_ignore) { mail_storage_set_error(t->box->storage, ME(NOTPOSSIBLE) "antispam signature not found"); return -1; /* <-- HERE */ } else { return 0; } } while (signatures[1]) signatures++; item = i_new(struct siglist, 1); item->next = *list; item->wanted = wanted; item->sig = i_strdup(signatures[0]); *list = item; return 0; } So, what's happening is "antispam signature not found". My question: What does this mean? What's going on? My "dovecot -n" output is attached. Bye Volker

Managing Sieve on macOS 10.12 Sierra with Server 5.2?
by Gerben Wierda 17 Dec '16

17 Dec '16

I don’t know if this is considered OT, but dovecot has support for sieve. I had a rule set running under Mac OS X 10.8.5 Server 2.2.5 which I did maintain by hand on the server because a while before Mac OS X Server had dropped support for Squirrelmail. Now I wonder if there is a decent way to get sieve running again on macOS 10.12 Sierra with Server 5.2 G

Existing shared mailbox ... does not exist
by Ruga 17 Dec '16

17 Dec '16

Hello, Dovecot 2.2.26.0 Thunderbird 45.4.0 ESR Scenario: We have a shared mailbox with e-mails in its subdirectories. There are no e-mails in the shared mailbox itself. Example: /Shared <----------------------------------- empty /Shared/call_for_papers <-------------- empty /Shared/call_for_papers/AAMAS <-- populated ...more of the same... Problem: When selecting /Shared, Thunderbird chirps this message: "The current operation on 'Shared' did not succeed. The mail server for account @example.com responded: Mailbox doesn't exist: Shared/Shared (0.000 + 0.000 secs)."

service(indexer-worker): child 18977 killed with signal 11 (core dumped)
by Matteo Biagini 16 Dec '16

16 Dec '16

Hello to everybody, first of all: thanks a lot for your hard work and for this nice piece of software! After many search about the following SIGSEGV, I decide to post the backtrace and I hope to have avoided duplicated thread. The problem arise after I enable clucene fts. I tryed the clucene ports version (I am using OpenBSD) and a fixed version from github (Blue-Rocket/clucene::feature/pod) which contains FreeBSD fixes and others memory leak patches, but the problem persists. I built either dovecot-* and clucene-core with -g and the following logs are taken from that version. Maybe, I can do more debugging but I don't know how; some ideas? thanks a lot == LOG == Dec 16 12:30:34 mail02 dovecot: indexer-worker(user@hostname): Indexed 1 messages in Trash Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=90234, TLS, session=<68Ny6MRDml8K9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=59810, TLS, session=<c7xz6MRDzV4K9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=66756, TLS, session=<UtNz6MRDiJwK9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=81959, TLS, session=<gJZ06MRD9HQK9ANl> Dec 16 12:31:16 mail02 dovecot: imap-login: Login: user=<user@hostname>, method=PLAIN, rip=10.244.3.101, lip=10.244.3.200, mpid=14099, TLS, session=<BL116MRD3DgK9ANl> Dec 16 12:31:16 mail02 dovecot: indexer-worker(user@hostname): Indexed 1 messages in INBOX Dec 16 12:32:18 mail02 dovecot: indexer-worker: Fatal: master: service(indexer-worker): child 18977 killed with signal 11 (core dumped) == GDB == (gdb) bt #0 strlen () at /usr/src/lib/libc/arch/amd64/string/strlen.S:152 #1 0x0000093434d7c120 in __vfprintf (fp=0x7f7fffff96c0, fmt0=0x9343cef79ae "Timeout leak: %p (%s:%u)", ap=Variable "ap" is not available. ) at /usr/src/lib/libc/stdio/vfprintf.c:885 #2 0x0000093434d9b068 in *_libc_vsnprintf (str=0x933ab0940b8 "Timeout leak: 0x9342f652300", n=120, fmt=0x9343cef79ae "Timeout leak: %p (%s:%u)", ap=0x7f7fffff9870) at /usr/src/lib/libc/stdio/vsnprintf.c:61 #3 0x000009343cdd4aa5 in str_vprintfa (str=0x933ab094078, fmt=0x9343cef79ae "Timeout leak: %p (%s:%u)", args=0x7f7fffff9870) at str.c:129 #4 0x000009343cdaacd1 in internal_handler (ctx=0x9343d22fab0, format=0x9343cef79ae "Timeout leak: %p (%s:%u)", args=0x7f7fffff9870) at failures.c:602 #5 0x000009343cdab839 in i_internal_error_handler (ctx=Variable "ctx" is not available. ) at failures.c:677 #6 0x000009343cdab3f4 in i_warning (format=0x9343cef79ae "Timeout leak: %p (%s:%u)") at failures.c:325 #7 0x000009343cdc107b in io_loop_destroy (_ioloop=Variable "_ioloop" is not available. ) at ioloop.c:741 #8 0x000009343cd485bd in master_service_deinit (_service=Variable "_service" is not available. ) at master-service.c:876 #9 0x0000093193802642 in main (argc=1, argv=0x7f7fffff9b28) at indexer-worker.c:83 (gdb) bt full #0 strlen () at /usr/src/lib/libc/arch/amd64/string/strlen.S:152 No locals. #1 0x0000093434d7c120 in __vfprintf (fp=0x7f7fffff96c0, fmt0=0x9343cef79ae "Timeout leak: %p (%s:%u)", ap=Variable "ap" is not available. ) at /usr/src/lib/libc/stdio/vfprintf.c:885 mbs = { __mbstate8 = "{\t\000\000\000\000\000\000\000\000\000\000r3\t\000\000\000\000\000\000\000\000\000\0004\t\000\000\001\000\000\000\000\000\000\000223\177\177\000\000\001\000\000\000\000\000\000\000\002\000\000\000\000\000\000\000\t216U\035\rP", '\0' <repeats 47 times>, __mbstateL = 10118011532464} mbseqlen = Variable "mbseqlen" is not available. == DOVECONF == #

making a plugin encrypt index data
by micah anderson 16 Dec '16

16 Dec '16

Hello, I'm encrypting mail on disk using a plugin[0], but the index files are not encrypted (specifically the dovecot.index.cache can be read). I want to do is encrypt index on disk, so I'm looking for how a plugin can achieve that by hooking into the right locations. Is that easily possible in a plugin? I can turn off those indexes by passing INDEX=MEMORY, but that isn't possible if I use sdbox/mdbox. thanks for any suggestions! micah 0. https://0xacab.org/riseuplabs/tofu-scrambler

Hi, at the moment I see only packages named *2.2.26* on xi.dovecot.fi. Can we expect packages for v2.2.27 to appear there? -- Regards mks

public folder subscriptions sync issue with ldap user/group in dovecot-acl
by Mike Fröhner 16 Dec '16

16 Dec '16

Hello people, I am having an issue with 'doveadm sync'. I am currently trying to have two dovecots behind an haproxy (works fine). Therefore I configured these two dovecot server (imap-1/imap-2) to sync throught dsync. This works just partly. The sync of the maiboxes is fine, but the sync of the subscriptions file just works partly. It works for private folder subscription, but not completly for public folder subscription. I found two issues, if I am using LDAP (user/groups) in dovecot ACLs. 1. I would like to subscribe 2 public folder (public/test/test1 and public/test/test2). My user (ldaptestuser) is an ldap user and this user is member of the ldap group (ldaptestgroup) which does have all dovecot-acl rights on these folders. imap-1 # cat /opt/mail/_public/publictest/.test*/dovecot-acl group=ldaptestgroup akxeilprwts group=ldaptestgroup akxeilprwts I am now connecting with my mail client to imap-1 (throught haproxy) and the subscription to this folder works. The file which is written looks like: imap-1 # cat /opt/mail/ldaptestuser/Mails/subscriptions Sent publictest/test/test1 publictest/test/test2 Now I am awaiting the synch to imap-2, but the file which it written looks like: imap-2 # cat /opt/mail/ldaptestuser/Mails/subscriptions Sent If I modify the dovecot-acl for .test1 to imap-1 # cat /opt/mail/_public/publictest/.test1/dovecot-acl group=ldaptestgroup akxeilprwts user=ldaptestuser akxeilprwts and execute the subscription again - the synced file looks like: imap-2 # cat /opt/mail/ldaptestuser/Mails/subscriptions Sent publictest/test/test1 The subscription of public folder test2 will also been synced, if I add my ldaptestuser to the acl file for this folder. 2. Another issue is to unsubscribe a public folder. If I unsubscribe folder test1, it is written to subscriptions file on the imap where I am connected, but it is NOT synced even if my user and group are configured at the dovecot-acl file. If I then unsubscribe a not public folder (like Sent), the former unsubscribed folder test1 is (faulty) subscribed again. But both imap do have the same subscriptions for my ldaptestuser user. I do have the behavior with dovecot-2.2.26 and dovecot-2.2.27 on CentOS-7 (selinux disabled). If you need more information like the dovecot -n or some other stuff give me a short notice. Mike;

autoexpunge=30d does not works :(
by Peter Hodur 16 Dec '16

16 Dec '16

Hello, just upgraded to Dovecot 2.2.27 and altered dovecot.conf to contain autoexpunge directive for Spam mailbox (yes it's migrated from Courier 3 years ago): namespace inbox { prefix = INBOX. separator = . inbox = yes mailbox Archive { auto = subscribe special_use = \Archive } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Spam { auto = subscribe special_use = \Junk autoexpunge = 30d } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } } As I hope, when user logout (POP3 or IMAP) or after Postfix delivers mail via LMTP, Dovecot should check Spam folder for emails, which have ctime older than 30 days and deletes this emails. Recently I have tried this. I have tried login / logout and nothing happend. I have tried turning log verbosity to debug but I can not find any note in debug.log according to this. I would like to kindly ask someone for which this directive works to help me, what is wrong with my config or how can I debug it and find error. Thanks Pete

Possible solr and indexing bug
by Netfront Customer Service 16 Dec '16

16 Dec '16

Bug Report: We had one of our solr server down for a while, then observed a lot of "Warning: fscking index file " actions. Version 2.2.27 with auto fsck. A follow up investigation shows direct one to one relationship between solr error and subsequent fscking. The fscking lasts for quite a long time (for at least an hour) when the mailbox is concurrently accessed. Thank you.

Configuration problem for secure virtual server
by Karsten Malcher 15 Dec '16

15 Dec '16

Hello, i want to configure a virtual mailsystem on an debian server with exim and dovecot. Because it is running on a V-Server, i want to store everythink in a LUKS encrypted contrainer. So i created a group crypt with the members Debian-exim (107), dovecot, (other users with encrypted content) All mails should be stored in /mail in the mounted container. Dovecot has this configuration: ======================================= passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = static args = uid=Debian-exim gid=mail home=/mountpoint/mail/%d/%n } mail_uid = Debian-exim first_valid_uid = 107 last_valid_uid = 107 first_valid_gid = 8 last_valid_gid = 9 mail_location = maildir:/mountpoint/mail/%d/%n ======================================= The /mountpoint has the following rights: drwxrwx--- 5 root crypt 4,0K Dez 13 19:05 mountpoint The subdirectories are all owned by Debian-exim: drwxrwx--- 4 Debian-exim mail 4,0K Okt 23 17:05 mail The group mail has id 8 and the group crypt has id 9 The Problem is that dovecot will not go into the directory with group crypt! I always get the following error message: Dec 15 18:03:25 pop3(karsten@server): Error: user karsten@server: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/mountpoint/mail/server/karsten) failed: Permission denied (euid=107(Debian-exim) egid=8(mail) missing +x perm: /mnt, we're not in group 9(crypt), dir owned by 0:9 mode=0770) Dec 15 18:03:25 pop3(karsten@server): Error: Invalid user settings. Refer to server log for more information. But dovecot is definitely in the group crypt! What i am doing wrong? Regards Karsten

Maildir: do message files need to have a unique name across all directories?
by Gerben Wierda 15 Dec '16

15 Dec '16

While testing a new mail server I created a temporary account and filled its mailbox (Milder, dovecot) with the contents of another account. That means the actual message files in each account have identical names. Is that a problem? (I’m asking because I see some weird behaviour of visible/invisible messages and I wonder if this could have been the reason). G

postlogin script
by Michael Fox 14 Dec '16

14 Dec '16

I'm using the postlogin service, following the examples in the wiki. But I can't find any documentation on the behavior (what's allowed/not allowed) of the script-login binary. So, some questions: Question 1: The examples show the following at the end of the post-login.sh script: exec "$@" My understanding is that this would exec each of the command line arguments to the post-login.sh script. But, there are no arguments sent to the post-login.sh script in the examples. So what is this line supposed to do? Question 2: One of the examples shows exporting some environmental variables, followed by the above exec line: export MAIL=maildir:/tmp/test export USERDB_KEYS="$USERDB_KEYS mail" exec "$@" Now, I'm really confused. Can someone explain step-by-step why this does anything at all? Question 3: I'd like to be able to pass some information to the post-login.sh script, such as the service (%s), as a positional parameter. For example: executable = script-login /path/post-login.sh %Ls Or even more explicitly: executable = script-login /path/post-login.sh imap But it appears that the script-login binary is expecting only script names to be passed to it so that it can handle more than one script. Is there a way to pass arguments to the different scripts? Thanks, Michael

mailboxes and capitalisation
by Thorsten Hater 14 Dec '16

14 Dec '16

Dear all, I have set up a series of special-use mailboxes in the default namespace differing by capitalisation of the names, mainly to capture multiple mailboxes with autoexpunge namespace inbox { ... mailbox Trash { auto = no autoexpunge = 30d special_use = \Trash } mailbox trash { auto = no autoexpunge = 30d special_use = \Trash } ... } However, doveconf -n reports only one mailbox, namely the second (lowercase t) and autoexpunge does not trigger for the first one (capital T). Removing the special use flag has no influence. namespace inbox { inbox = yes list = children location = ... mailbox trash { auto = subscribe special_use = \Trash } ... prefix = INBOX. separator = . subscriptions = yes type = private } Is this the intended behaviour? The example 15-mailboxes.conf seems to indicate otherwise and I would prefer the ability to set autoexpunge for both Trash and trash. (dovecot 2.2.26 built from source on Debian 8.0) Best regards, Thorsten

Simple way to get mailbox size by folder.

Is there a simple way to get each mailbox size using dovecot's IMAP interface? The GETQUOTAROOT and GETQUOTA seems to work with the full maildir size and not the individual folders. I am finding a simple way for the webmail client to show usage of each folder. Thanks Vijay

FTS solr info
by Brad Koehn 11 Dec '16

11 Dec '16

Are there updated instructions on setting up FTS with solr? I’m in the midst of upgrading my site and the links don’t appear to work or be applicable to current versions of solr. I grabbed 6.3.0 from apache and the instructions are no longer working, e.g., there’s no `solr/conf/schema.xml` file to replace; the `start.jar` has moved, etc. Just wondering if there’s somewhere else I should look, or if I should just hack it together on my own. Thanks! Brad Koehn

doveadm-server uses 100% cpu and never finishes, dsync backup also never finishes
by Patrick van Zweden 09 Dec '16

09 Dec '16

Hi Guys, I have a quite interesting problem. I have two servers that replicate to each-other. Suddenly one of the accounts is starting to eat a very large amount of disk space on, what basically is the replica for this account. doveadm-server seems to hang and keeps on filling the disk. I came across this message in the logs: Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal: pool_system_malloc(6291528): Out of memory Dec 8 07:36:40 <server> dovecot: dsync-server(<account>): Fatal: master: service(doveadm): child 883 returned error 83 (Out of memory (service doveadm { vsz_limit=256 MB }, you may need to increase it) - set DEBUG_OUTOFMEM=1 environment to get core dump) I’ve increased the vsz_limit to 5G so it has stopped complaining. Only… the process never seems to finish. I’ve tried to export the mailbox using dsync: dsync -Dv backup -u 'xxxxx' sdbox:/tmp/patrick_export/ However this process never finishes either. It looks like it stays in one of the mailboxes and keeps on trying to copy messages. Format of the mailbox is sdbox Version of dovecot on all servers: 2.2.9 Any pointers for solving this problem? Kind regards, Patrick -- Patrick van Zweden

doveadm

Hello list, I'm interested in setting up dovecot replication but when I run the command doveadm user '*', which is necessary as indicated here: http://wiki2.dovecot.org/Replication, I get the following output: Error: User listing returned failure Fatal: user listing failed It also indicates the following on the wiki2: "Make sure that user listing is configured for your userdb, this is required by replication to find the list of users that are periodically replicated" I use a vpopmail backup so the question is how do I "Make sure that user listing is configured for...userdb"? This is my userdb settings for vpopmail: userdb { args = cache_key=%u quota_template=quota_rule=*:backend=%q driver = vpopmail } Thank-you Eric

Correct user for replication
by John Fawcett 08 Dec '16

08 Dec '16

Hi I've set up replication with the settings below. With these settings, aggregator runs as user dovecot and replicator as user root. Are those the recommended settings or should I change them, in particular for replicator which is running as a privileged user? service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = vmail } unix_listener replication-notify { mode = 0666 user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0660 group = mail } } service doveadm { inet_listener { port = 999 ssl = yes } } ssl_client_ca_file = /etc/pki/tls/cert.pem doveadm_password = secret plugin { mail_replica = tcps:hostname.domainname.tld:999 } thanks John

Migrate from dovecot 1.1 to 2.2 Maildir to 2.2 mdbox
by Daniel Betz 08 Dec '16

08 Dec '16

Hello list, im am trying to migrate customer mails via dsync from an old dovecot 1.1 setup to an new installed dovecot 2.2.25 setup with mdbox. Upgrading the old dovecot 1.1 to 2.2 with Maildir isnt an problem and the replication to the new setup works well too. The only problem now is, that the POP3 UIDL are completely wrong on the target setup. Im using for Maildir pop3_uidl_format = %f With mdbox i cant use it anymore. But what do i need for mdbox ? Or is there an way to migrate the POP3 uidl list to the mdbox ? I could live with it, when i were able to mark the mails older 14 days as read. Is there an way to do this on many mailboxes ? I have read in Release News from 2.2.26 that there are some fixes with POP3 UIDL .. what is it in detail and could it help me ? Hop you can point me to the right direction.

Dovecot: Mails flagged as read get flagged as unread
by plataleas 07 Dec '16

07 Dec '16

Hi all We experience some unexpected behavior with dovecot. It happens that emails marked as read get marked as unread (MUA is Thunderbird on port 143). Unfortunately this happens randomly, reproducing this issue is difficult. We could not find any pattern, it happens rarely. We are running dovecot version 2.2.24 on Debian Jessie (backports repository). /root@dovecot01:~# dovecot --version// //2.2.24 (a82c823)/ Our Setup: /ha-proxy01 -> dovecot-proxy01 (proxy=yes) -> dovecot01 (proxy=no) * IP is used for multiple services (ports). We use the haproxy to send traffic on different ports to different servers. / Below the configuration (IMAPC is active for migration purposes). Do you have any recommendations where we could focus for troubleshooting? I found some posts about mbox_lazy_writes causing similar issues. However we use mdbox in our setup. If we enable rawlog for what log patterns should we search? Your Inputs are highly appreciated! Thanks and Regards plataleas *----- haproxy configuration ------ *frontend frontend_mail.company.org-143 bind 10.100.189.34:143 mode tcp default_backend backend_mail.company.org-143 backend backend_mail.company.org-143 mode tcp balance source server dovecot-proxy01.company.org dovecot-proxy01.company.org:10143 check send-proxy-v2 server dovecot-proxy02.company.org dovecot-proxy02.company.org:10143 check send-proxy-v2 backup *----- config Dovecot Proxy -----* /root@dovecot-proxy01:~# dovecot -n #

Dovecot migration via dsync : mail_location problem (INBOX) ?
by Cédric ML 07 Dec '16

Hello, I'm trying to migrate mail accounts from an old dovecot 1.0.15 to a new dovecot 2.2.26. I've set up a master-user on old dovecot, and I run dsync on new server, like this : # doveadm -D -o mail_fsync=never sync -R -u user(a)domain.tld imapc: my user(a)domain.tld looks like this (on the new server): # doveadm user user(a)domain.tld field value uid 2000 gid 2000 home /home/vmail/domain.tld/user mail maildir:/home/vmail/domain.tld/user/mail quota_rule *:bytes=0 User mail folder on the old server looks like this : # ls -la /home/virtual/user(a)domain.tld/ total 64 drwx------ 11 vmail vmail 4096 2016-12-06 16:26 ./ drwxrwx--- 234 vmail vmail 12288 2016-12-05 12:57 ../ drwx------ 2 vmail vmail 89 2016-12-06 15:29 cur/ -rw------- 1 vmail vmail 352 2016-12-06 16:26 dovecot.index -rw------- 1 vmail vmail 19456 2016-12-06 16:26 dovecot.index.cache -rw------- 1 vmail vmail 2220 2016-12-06 16:26 dovecot.index.log -rw------- 1 vmail vmail 10 2016-12-06 15:14 dovecot-keywords -rw------- 1 vmail vmail 170 2016-12-06 16:21 dovecot-uidlist drwx------ 5 vmail vmail 148 2016-12-05 16:52 .Drafts/ drwx------ 5 vmail vmail 148 2016-12-05 16:52 .FauxIndesirable/ drwx------ 5 vmail vmail 148 2016-12-05 16:52 .Indesirable/ -rw-r----- 1 vmail vmail 293 2016-12-06 15:29 maildirsize drwx------ 2 vmail vmail 85 2016-12-06 15:29 new/ drwx------ 5 vmail vmail 148 2016-12-05 16:52 .Sent/ drwx------ 5 vmail vmail 148 2016-12-05 16:52 .Spam/ drwx------ 2 vmail vmail 6 2016-12-07 10:46 tmp/ drwx------ 5 vmail vmail 4096 2016-12-06 15:36 .Trash/ When I run the sync, with "doveadm -D -o mail_fsync=never sync -R -u user(a)domain.tld imapc:" on the new server, the new server synchronises the mail from the new server, and the file system on the new server looks like this : root@dovecot-pa3:/home/vmail/domain.tld# ls -la /home/vmail/domain.tld/user/mail/ total 84 drwx------ 15 mailbox mailbox 4096 Dec 7 11:02 . drwx------ 3 mailbox mailbox 4096 Dec 7 11:02 .. drwx------ 2 mailbox mailbox 4096 Dec 7 11:02 cur -rw------- 1 mailbox mailbox 556 Dec 7 11:02 dovecot.index.log -rw------- 1 mailbox mailbox 96 Dec 7 11:02 dovecot.mailbox.log -rw------- 1 mailbox mailbox 51 Dec 7 11:02 dovecot-uidlist -rw------- 1 mailbox mailbox 8 Dec 7 11:02 dovecot-uidvalidity -r--r--r-- 1 mailbox mailbox 0 Dec 7 11:02 dovecot-uidvalidity.5847de3b drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .Drafts drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .INBOX.Drafts drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .INBOX.FauxIndesirable drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .INBOX.Indesirable drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .INBOX.Sent drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .INBOX.Spam drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .INBOX.Trash drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .Junk -rw------- 1 mailbox mailbox 17 Dec 7 11:02 maildirsize drwx------ 2 mailbox mailbox 4096 Dec 7 11:02 new drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .Sent -rw------- 1 mailbox mailbox 23 Dec 7 11:02 subscriptions drwx------ 2 mailbox mailbox 4096 Dec 7 11:02 tmp drwx------ 5 mailbox mailbox 4096 Dec 7 11:02 .Trash But dovecot is condigured to have ".Trash", ".Junk" etc... folders, not ".INBOX.Trash" I've try multiple things : - use namespaces for compatibility and add "-n <namespace>" in sync command, without success - modify the mail_location for the user, tried to add LAYOUT=fs, INBOX=<folder>, ... without success.

This happened more easily with IMAP hibernation enabled. - Various fixes to restoring state correctly in un-hibernation. - dovecot.index files were commonly 4 bytes per email too large. This is because 3 bytes per email were being wasted that could have been used for IMAP keywords. - Various fixes to handle dovecot.list.index corruption better. - lib-fts: Fixed assert-crash in address tokenizer with specific input. - Fixed assert-crash in HTML to text parsing with specific input (e.g. for FTS indexing or snippet generation) - doveadm sync -1: Fixed handling mailbox GUID conflicts. - sdbox, mdbox: Perform full index rebuild if corruption is detected inside lib-index, which runs index fsck. - quota: Don't skip quota checks when moving mails between different quota roots. - search: Multiple sequence sets or UID sets in search parameters weren't handled correctly. They were incorrectly merged together.

Hi, Here is a crash that's happening using the latest Dovecot version (v2.2.27 on CentOS7 x86_64): We are using replication. Judging by the second server's logs, I believe this has something to do with the fact that we're using the lazy_expunge plugin. Every night after midnight, we purge the lazy_expunge namespace by running a command similar to following one on the main server (server01 in the logs below): # doveadm expunge -A MAILBOX 'EXPUNGED/*' SAVEDBEFORE "$(date +'%F')" The lazy_expunge namespace is configured as follows: namespace expunged { disabled = no hidden = yes ignore_on_failure = no inbox = no list = no location = sdbox:/srv/mail/expunged/%1n/%n:SUBSCRIPTIONS=subscriptions-expunged order = 0 prefix = EXPUNGED/ separator = / subscriptions = no type = private } plugin { lazy_expunge = EXPUNGED/ } First server's logs: 2016-12-06T13:09:31.212620+01:00 server01 dovecot: dsync-server(user01): Panic: file dsync-mailbox-tree-sync.c: line 576 (node_mailbox_trees_cmp): assertion failed: (ret != 0) 2016-12-06T13:09:31.213473+01:00 server01 dovecot: dsync-server(user01): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x92d70) [0x7f57cc18ad70] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x92e4e) [0x7f57cc18ae4e] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f57cc1264e0] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x447584] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x447a57] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x447849] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x447849] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes](dsync_mailbox_trees_sync_init+0x1f9) [0x447cc9] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes](dsync_brain_recv_mailbox_tree_deletes+0x207) [0x43a477] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes](dsync_brain_run+0x5fe) [0x436e4e] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x437280] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x44c5af] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7f57cc19e4d2] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xe7) [0x7f57cc19fa07] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7f57cc19e56c] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f57cc19e728] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x41faae] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x421316] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x433b64] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7f57cc19e4d2] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xe7) [0x7f57cc19fa07] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7f57cc19e56c] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f57cc19e728] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f57cc12c513] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes](main+0x197) [0x413b57] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f57cbd57b15] -> dovecot/doveadm-server [10.0.0.2 user01 recv_mailbox_tree_deletes]() [0x413bf5] 2016-12-06T13:09:31.214076+01:00 server01 dovecot: dsync-server(user01): Fatal: master: service(doveadm): child 6837 killed with signal 6 (core dumps disabled) 2016-12-06T13:11:42.880516+01:00 server01 dovecot: dsync-local(user01): Error: read(server02.localdomain) failed: EOF (last sent=mailbox_delete, last recv=mailbox_tree_node) Second server's logs: 2016-12-06T12:09:36.220591+01:00 server02 dovecot: doveadm(user01): Error: Duplicate mailbox GUID eab35824e49b4658840001001776124f for mailboxes EXPUNGED/Trash/C2i -

LMTP delivery honours .forward by default?
by MRob 06 Dec '16

06 Dec '16

I was under the impression that Dovecot does not look at .forward by default, since of course, Sieve is where that kind of logic should go. However, I'm seeing a .forward file being honoured by the LMTP delivery agent. Is this to be expected?

COPY vs APPEND for imapsieve?
by MRob 06 Dec '16

06 Dec '16

The examples on the imapsieve documentation page use COPY but not APPEND to watch messages coming into a folder. Are there not circumstances that a client would APPEND a message to a folder instead of COPY? Is APPEND only used by most clients for adding a sent message to the sent folder? I'm not familiar enough with IMAP clients to know if by leaving off APPEND I am safe or I am at risk to miss some actions I shouldn't.

imapsieve environment variables missing?
by MRob 06 Dec '16

06 Dec '16

RFC6785 says imap.user and imap.email environment variables should be made available but I can't access them no matter what I try. Are they not implemented because vnd.dovecot.environment already provides the username? (which does work for me) If imap.user and imap.email are there, can you provide an example how to access them so I can see what I did wrong?

https://dovecot.org/releases/2.2/dovecot-2.2.27.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.27.tar.gz.sig Note that the download URLs are now https with a certificate from Let's Encrypt. * dovecot.list.index.log rotation sizes/times were changed so that the .log file stays smaller and .log.2 is deleted sooner. + Added mail_crypt plugin that allows encryption of stored emails. See http://wiki2.dovecot.org/Plugins/MailCrypt + stats: Global stats can be sent to Carbon server by setting stats_carbon_server=ip:port + imap/pop3 proxy: If passdb returns proxy_not_trusted, don't send ID/XCLIENT + Added generic hash modifier for %variables: %{<hash algorithm>;rounds=<n>,truncate=<bits>,salt=s>:field} Hash algorithm is any of the supported ones, e.g. md5, sha1, sha256. Also "pkcs5" is supported using SHA256. For example: %{sha256:user} or %{md5;truncate=32:user}. + Added support for SHA3-256 and SHA3-512 hashes. + config: Support DNS wildcards in local_name, e.g. local_name *.example.com { .. } matches anything.example.com, but not multiple.anything.example.com. + config: Support multiple names in local_name, e.g. local_name "1.example.com 2.example.com" { .. } - Fixed crash in auth process when auth-policy was configured and authentication was aborted/failed without a username set. - director: If two users had different tags but the same hash, the users may have been redirected to the wrong tag's hosts. - Index files may have been thought incorrectly lost, causing "Missing middle file seq=.." to be logged and index rebuild. This happened more easily with IMAP hibernation enabled. - Various fixes to restoring state correctly in un-hibernation. - dovecot.index files were commonly 4 bytes per email too large. This is because 3 bytes per email were being wasted that could have been used for IMAP keywords. - Various fixes to handle dovecot.list.index corruption better. - lib-fts: Fixed assert-crash in address tokenizer with specific input. - Fixed assert-crash in HTML to text parsing with specific input (e.g. for FTS indexing or snippet generation) - doveadm sync -1: Fixed handling mailbox GUID conflicts. - sdbox, mdbox: Perform full index rebuild if corruption is detected inside lib-index, which runs index fsck. - quota: Don't skip quota checks when moving mails between different quota roots. - search: Multiple sequence sets or UID sets in search parameters weren't handled correctly. They were incorrectly merged together.

doveadm edit headers?
by MRob 05 Dec '16

05 Dec '16

Hello, is there a way to edit a message header using doveadm? I see how I can fetch the things I need, but even if I can't edit in place; if I extract the full message, edit it, there doesn't seem to be a way to append it back again?

Virtual mailboxes, please help
by Peter Hodur 05 Dec '16

05 Dec '16

Hi, I'm trying to setup virtual mailboxes. My setup: - migrated from Courier, so: separator = . prefix = INBOX. inbox = yes In doc i have read, thant i need to create separate namespace. namespace { prefix = virtual/ separator = / location = virtual:~/Maildir/virtual So i need to change / with . (Dot) in prefix and separator? Do i need to append LAYOUT=maildir++ to location? Where must location point? To the same directory where mail_location? Or do i need to create separate hierarchy for virtual mailboxes? Thanks for any answer ;) Peter ml.

Mail marked read upon download
by Curtis Vaughan 05 Dec '16

05 Dec '16

Just set up a new server with postfix and dovecot. I don't know why, but as soon as mail is accessed it is marked read. I'll see emails momentarily marked unread, but then switch to read later although I haven't opened them. This has never been an issue before. Any ideas why? Thanks. Curtis

CVE-2016-8562 in dovecot
by Aki Tuomi 05 Dec '16

05 Dec '16

We are sorry to report that we have a bug in dovecot, which merits a CVE. See details below. If you haven't configured any auth_policy_* settings you are ok. This is fixed with https://git.dovecot.net/dovecot/core/commit/c3d3faa4f72a676e183f34be960cff1… and https://git.dovecot.net/dovecot/core/commit/99abb1302ae693ccdfe0d57351fd42c… Important vulnerability in Dovecot (CVE-2016-8562) CVSS score: 7.4 (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:H) Affected version(s): 2.2.25.1 up to 2.2.26.1 Fixed in: 2.2.27.1rc1 Short summary: Dovecot auth component can be crashed by remote user when auth-policy component is activated. If auth-policy component has been activated in Dovecot, then remote user can use SASL authentication to crash auth component. Workaround is to disable auth-policy component until fix is in place.

SAML | Input buffer full (no auth attempts in 0 secs)
by mj 04 Dec '16

04 Dec '16

Hi, In my journey to enable SAML auth for our webmail (sogo.nu) I have created a password-less dovecot imap listener on 127.0.0.1/32, so that once a user is SAML authenticated for the SOGo webmail, SOGo can connect to dovecot on 127.0.0.1:143 with something like "01 LOGIN username randompassword". Watching this (tcpflow) as it happens,i can see the following auth attempt coming from sogo: > 1 login "username" "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" Note, the actual 'password' is even longer.

Assuming that "barbu.sytes.net" is the intended hostname (not something made up to obscure the real name), there is an MX-record for that that points to "mail.barbu.sytes.net", but there is no A-record for the "mail." hostname. There is an A-record for "mail.sytes.net", in case that is what you were intending, in which case you'd need to fix the MX on "barbu.sytes.net".

How can I query the current pigeonhole version from a running instance to verify it is what I expect? Possible to get `dovecot --version` to show things like that?

CentOS 7
by Eric Broch 04 Dec '16

04 Dec '16

Hello List, I'm building a dovecot-2.2.27 RPM for CentOS 7 and running into some issues The dovecot.spec (http://pkgs.fedoraproject.org/cgit/rpms/dovecot.git/tree/dovecot.spec) file runs 'autoreconf -I . -fiv' for aarch64 support just before the %configure option but is failing This worked fine on <= 2.2.26.0 when there was an m4/*.m4 directory (with *.m4 in it) in the sources. Is there something I should be aware of? Was the m4 directory removed for a reason? As a workaround I created the m4 directory and everything worked out, but is this the best solution? Eric

Too many references: cannot splice

Hello, multiple times per day one of our Dovecot servers has the problem that it suddenly refuses to accept new connections and then floods the logs with these messages: Dec 2 12:43:06 alfa3201 dovecot: pop3-login: Error: fd_send(pop3, 18) failed: Too many references: cannot splice Dec 2 12:43:07 alfa3201 dovecot: pop3-login: Error: fd_send(pop3, 18) failed: Too many references: cannot splice Dec 2 12:43:07 alfa3201 dovecot: imap-login: Error: fd_send(imap, 16) failed: Too many references: cannot splice Dec 2 12:43:07 alfa3201 dovecot: imap-login: Error: fd_send(imap, 16) failed: Too many references: cannot splice We have to either do a restart of the server or a doveadm kick on all users to make it reachable again.

Defining INDEX target to other location than maildir seems to have no effect.
by Julian Sternberg 02 Dec '16

02 Dec '16

Dovecot Version 2.2.13 Linux Distribution: Debian Jessie CPU Architecture: x64 Filesystem: GlusterFS/NFS, XFS for Base System/Index Files. Two Dovecot/Postfix nodes accessing same GlusterFS/NFS Maildir. Regardless what i choose in mail_location (:INDEX=MEMORY or :INDEX=/var/indexes/%d/%n) all Mailbox index files will still get created within the users mail_location maildir: ~/Maildir My mail_location Maildir directory is shared on GlusterFS mount so i need to get index files away from this share due locking mechanism and faster caching. The weird is, if i set INDEX to /var/indexes, the index files getting created sometimes but then not updated frequently and exist parallel on Maildir which are mostly newer than on /var/indexes. If you delete the dovecot.index* files from Maildir, they will get recreated immediatly on Imap access but not on the alternative set INDEX location, they are getting recreated within Maildir again.

maildir-size-fix.pl - The file command can wrongly detect gzipped mails as being Minix filesystems
by Rarylson Freitas 02 Dec '16

02 Dec '16

Hi, Some days ago, I have used the maildir-size-fix.pl script (cited in this mail thread: http://www.dovecot.org/list/dovecot/2013-January/087942.html, in available here: http://dovecot.org/tools/maildir-size-fix.pl) This is a very good script and helped me a lot! However, some compressed mails where misdetected as non-compressed mail. So I discovered that some versions of the file command (some old versions) can wrongly detect gzipped files as being Minix filesystems. Actually, the error was occurring in about 1 gzipped mail for each 60000 or 100000 mails. I reported this file command bug here: https://bugs.launchpad.net/ubuntu/+source/file/+bug/1646233. But I think it's worth to make a small improvement in maildir-size-fix.pl, making it more error prone. What do you, guys, think about this? This is the patch I'm proposing: ``` --- maildir-size-fix.pl.orig 2016-12-01 14:41:30.044689101 -0200 +++ maildir-size-fix.pl 2016-12-01 14:49:42.971197715 -0200 @@ -37,7 +37,10 @@ return $stat[7]; } - my $type=`file "$path"`; + # Detecting all possible types (keep going) since some versions of the file + # command can wrong detect gzip files as Minix filesystems. + # See: https://bugs.launchpad.net/ubuntu/+source/file/+bug/1646233 + my $type=`file -k "$path"`; my $program = ""; if ($type =~ /gzip/) { $program = "gunzip"; ``` -- *Rarylson Freitas*

Implementing secondary quota w/ "Archive" namespace
by Fred Turner 01 Dec '16

01 Dec '16

Hello folks— My first post, so please be gentle… :-) I have a client email server using SSDs for primary user mailboxes, but since the number of users keeps growing and they all seem to be very reluctant to delete anything, I’ve implemented an “Archive” namespace that stores its mailboxes on a larger HD RAID. The idea is that, as the users approach their quota, they move messages to the Archive mailboxes to alleviate space in their primary Inbox namespace. This secondary storage part is working well, but I’m having trouble w/ getting the quotas to work right. Here are the basics of the setup: Mac Pro Server 2012 Mac OS X Server 10.6.8 Dovecot 1.1.20apple0.5 Here is how I’ve configured my namespaces (during testing): namespace private { separator = / prefix = inbox = yes } namespace private { separator = / prefix = testArchive/ location = maildir:/Shared Items/MailArchive/%u subscriptions = yes } My quota research has led me to try this: quota = maildir:User quota:ns= quota2 = maildir:ns=testArchive/ quota2_rule = *:storage=20G The first line is already in the default config, with the exception of the added “:ns=“ at the end. The 2nd line in the examples I saw had a middle component w/ the quota name, but when I tried that, like so: quota2 = maildir:Archive quota:ns=testArchive/ my server fails and shows this in the logs: > Fatal: IMAP(*): Quota root test backend maildir: Unknown parameter: ns=testArchive/ Any idea why it doesn’t like that? Also, do I need to add a quota_rule for the primary quota? It does not have one normally in the Mac OS X Server config… Thus far in my testing, I’ve been able to get the 2 quotas to show up in Roundcube and Mac Mail.app. It’s a little messy…the first shows up as “User quota”, the 2nd as “ns=testArchive/“, presumably because I cannot leave the description field in there. Unfortunately, both quotas show the same amount of space in use. If I drop the primary quota to a mere 4MB for testing, and if I have 5.2MB of messages in a testArchive folder, the space used for “User quota” shows as 5.2MB (>100%), as does the “ns=testArchive/“ quota (which is 20GB). In actuality, the Inbox namespace is really only using a few KB— the 5.2MB is in the testArchive namespace. This means that I cannot move messages between either set of namespaces, and new messages are not delivered. So, the quota trouble here is negating the whole point of having the Archive namespace... Is there a way to get Dovecot to “see” the 2 quotas as unique/discrete? It seems like I’m close to accomplishing what I want, but just can’t quite get it to cooperate. And that “Unknown parameter” error is bewildering. Any ideas? Thx, Fred P.S. I can add my Dovecot config to the thread upon request…didn’t want to make this initial message even longer.

AW: User unknown in local recipient table

Hallo Liste, hallo Ralf, danke schon mal. Ja die Whitespaces sind beim Rauslöschen entstanden. Ich verstand das so, dass das nun durch die address_verify_map erledigt würde. Muss ich dann entsprechend einfach auf die verweisen? Ich versuchte gerade die address_verify_map = btree:$data_directory/verify_cache auf local_recipient_maps = btree:$data_directory/verify_cache verweisen zu lassen. Leider ohne Erfolg. Bisher ist verify_cache nämlich leider noch unbefüllt. Entsprechend bekomme ich folgende Fehler: Dec 1 16:16:29 test-mail postfix/smtpd[5550]: warning: btree:/var/lib/postfix/verify_cache is unavailable. open database /var/lib/postfix/verify_cache.db: No such file or directory Dec 1 16:16:29 test-mail postfix/smtpd[5550]: warning: btree:/var/lib/postfix/verify_cache lookup error for "juergen @domain.org" Dec 1 16:16:29 test-mail postfix/smtpd[5550]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 451 4.3.0 <juergen.pittorf(a)doag.org>: Temporary lookup failure; from=<kalle(a)domain.org> to=<juergen(a)domain.org> proto=ESMTP helo=<test-mail.domain.org> Auch ein plumpes touch auf /var/lib/postfix/verify_cache.db bringt danach den selben Fehler.

Re: dovecot Digest, Vol 163, Issue 34
by J. Nick Koston 01 Dec '16

Aki, Multiple local_names would be ideal to accommodate certificates that have multiple names. The way I’m reading the code it looks like its having to pay for the memory for every name on the certificate because a unique CTX is being created for each name even if they are all on a single certificate. This would be a big memory win for anyone using a certificate with multiple names on it.

use IMAPSIEVE to update database with last_read date
by KT Walrus 30 Nov '16

30 Nov '16

Just noticed the Dovecot support IMAPSIEVE extension… Could I use this extension to update an external database with the date that the user last read the message? My app sends certain “notification” messages to the user’s dovecot mail address. The user reads the messages in their dovecot mailboxes only using IMAP. I want to update my app’s database to record this read time for all “notification” messages sent by the app. Seems to me I could write a short sieve script to send a “notify” message to an app specific address that my app “watches” and updates the appropriate database record with the last_read time. Is this workable for production deploy? Or, is there a better way for a sender to be notified when the recipient actually reads the message? The sender will be my app and the recipient is a dovecot mailbox accessed by IMAP. Kevin

Sieve script won't compile. Compiler output isn't helpful.
by Steven Mainor 30 Nov '16

30 Nov '16

Hello! I hope you will forgive my ignorance but I have a problem I have been trying to solve for a week and I'm not sure where else to turn. I'm trying to write a sieve script to sort all of my mail. I was writing this script to replace the one I am currently using but I can't seem to get it to compile. I don't know a lot about sieve or really scripting of any kind and I just can't figure out what I'm doing wrong. The compiler just puts out a bunch of output that doesn't make sense. like "unexpected character" when I know the character works there because I am already running a script with some of the same lines. I'm attaching the script with some names and addresses changed and the sieve output to this email. I would greatly appreciate any help anyone could offer.

Quota Clone not tracking unlimited quota
by Prakash Autade 30 Nov '16

30 Nov '16

We are configuring 'Count quota' with 'Quota Clone Plugin' Everything is working perfectly when we set limit in quota_rule(quota_rule = *:bytes=500M). In case of unlimited quota(quota_rule = *:bytes=0) - Count quota is updating values * - Quota Clone plugin is not updating values in redis.* We have configured dovecot as mail_plugins = $mail_plugins quota quota_clone mail_log notify mailbox_list_index = yes plugin { quota = count:User quota quota_vsizes = yes quota_rule = *:bytes=0 quota_clone_dict = redis:host=127.0.0.1:port=6379 } -- Sincerely, Prakash P. Autade.
