[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? Luckily it don't have the permission.. I tried to look in the source code for "delete from", but founded just a general sql handle method.

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
by Heiko Schlittermann 22 Jan '16

22 Jan '16

Hello, as may parts of the dovecot configuration docs refer to sieve and it's specific versions, like NOTE: Pigeonhole versions before v0.3.1 do not support the lo … how do I get the Pigeonhole version my local dovecot uses? The package version number of the ubuntu package dovecot-sieve isn't telling me anything here, because it's bound to the dovecot version number. What do I miss here? Thank you.

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
