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?

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.

sieve - content checks with special chars
by Hajo Locke 11 Jan '16

11 Jan '16

Hello, currently i try subject tests with special chars and german umlauts öäü etc. if header :contains "subject" ["öööö äää"] { fileinto "umlauts"; } iam surprised, this is working out of the box. great! in procmail i had to add a second step by manual coding the needle with perl. is sieve reliable at this kind of tests or are there some special cases? iam worried about this, because it was to easy. confusing... ;) Thanks, Hajo

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 10 Jan '16

10 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
