[Dovecot] Plugin issue with update from 2.0.19 to 2.1.17
by Reinaldo Matukuma 26 Oct '13

26 Oct '13

Hello. Probably only Timo can help-me with this. I have a self-made plugin based on the zlib plugin that i use to cryptograph the messages at inbox. As a side-effect of the cryptography, my plugin changes the size of the message, but until 2.0.19 this works well with dovecot index and the W/S flags. But now, i'm going to upgrade to 2.1.17 and now i have these messages on log at my test ambiance: Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Cached message size smaller than expected (367 < 529) Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Maildir filename has wrong S value, renamed the file from /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/cur/1381879158.M634385P5208.test,S=367,W=378:2,S to /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/cur/1381879158.M634385P5208.test,S=529:2,S Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Corrupted index cache file /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 6 I understood with these messages that the dovecot is arguing to get the real size of the file now, overriding the return of size from my crypto plugin. But i don't understood if this is a consequence from the changes to correct the index issue (the dovecot.index.cache issue). So... I want know if the correct way to fix this would be change my plugin to return the real size of the file (that will be larger than the effective message that the plugin returne after the de-cryptography) or if i need use some new function to the plugin replace the expected size based on the real size of the message, not of the file. Thanks Reinaldo

[Dovecot] Strange output from LIST command
by azurIt 26 Oct '13

26 Oct '13

Hi, i'm using Dovecot 2.1.7 (Debian Wheezy) and output from LIST command looks strange: C: 4 LIST () "" (INBOX INBOX.Karantena INBOX.Spam) RETURN (STATUS (UNSEEN)) S: * LIST () "." "INBOX" S: * LIST () "." "INBOX.Karantena" S: * STATUS "INBOX.Karantena" (UNSEEN 0) S: * LIST () "." "INBOX.Spam" S: * STATUS "INBOX.Spam" (UNSEEN 0) S: 4 OK List completed. The UNSEEN information for INBOX is completely missing. It is correct behavior? If not, is this a known bug in 2.1.7? Thank you. azur

[Dovecot] Login into other user's account // master user for non-master users // chroot to users.<user>
by Steffen Kaiser 26 Oct '13

26 Oct '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Currently some of our organizational roles uses shared secrets (aka the password) to access the mail account of an organizational role, say "sales" for example. For one, I don't like shared secrets, for second, there had been some changes to shared mailboxes, I can only say "user sales has deleted the message at then and then". Therefore I would like to access the mailboxes of organizational roles with the accounts of the humans performing the role currently. Using sharing and ACLs it is possible to map the mailboxes of "sales" to "users.sales" namespace for specific other users, actually the human ones, say userA and userB for example. However, userB does not like managing identities in its MUA and refuses to acknowledge the messages in users.sales for various reasons. One reason was that userB wants to visibly separate strictly both mail accounts, the private messages in "userB" and the role's ones in "sales". Now, I came into thinking that it would be good in such case, if userB could authentificate as, say "sales*userB" - much like a master user - and ends in "sales"'s home, but with access permissions of "userB", well, like a chroot. Would it be an interesting feature to add to Dovecot's core? If I simulate "sales*userB" with password of userB and let the userdb return the home of sales, userB would gain "owner" privilegues of sales implicitly. So there seems to exist no workaround.

[Dovecot] LMTP, TLS/SSL, authentication, proxy
by Jogi Hofmüller 26 Oct '13

26 Oct '13

Folks, Several questions packed into one email ;) Can dovecot use TLS/SSL on LTMP inet socket? Can I configure dovecot to only let an authenticated user deliver mail via LMTP? Can I tell dovecot to use a user/password for proxying LMTP connections? All this is related to my quest to move from cyrus to dovecot transparently to our users. And if any of the above questions can be answered with yes, I would appreciate the odd hint on howto configure that :) Thanks in advance! -- j.hofmüller aka Thesix http://users.mur.at/thesix/

[Dovecot] Empty Mails from MAILER-DAEMON with Dovecot-Antispam and DSPAM
by Anna Christina Naß 26 Oct '13

26 Oct '13

Hallo, I've installed the dovecot-Antispam extension to my dovecot IMAP installation in conjunction with DSPAM. But when moving Mails from e.g. INBOX to Spam or vice versa, empty mails from MAILER-DAEMON appear after the original mail has been moved. This happens using Thunderbird 17esr, K-9 Mail on Android and Apple Mail (Mountain Lion). (Perhaps also when using a Webmail IMAP client) The source from one of these empty mails looks like this: ----snip---- Return-Path: <MAILER-DAEMON> X-Original-To: acn Delivered-To: acn(a)mydomain.name Received: from localhost (localhost.localdomain [127.0.0.1]) by <my host name> (Postfix) with SMTP id CB81B140011 for <acn>; Thu, 24 Oct 2013 09:23:33 +0200 (CEST) X-DSPAM-Reclassified: Spam Message-Id: <20131024072333.CB81B140011@<my host name>> Date: Thu, 24 Oct 2013 09:23:33 +0200 (CEST) From: MAILER-DAEMON ----/snip---- Do you have any idea why these mails appear and how I can prevent it?

[Dovecot] UIDL conversion courier -> dovecot
by Will Yardley 25 Oct '13

25 Oct '13

I've got a weird split setup where POP3 is currently handled by Courier (courier-imap-3.0.2 distribution), and IMAP is currently handled by the RHEL 5 version of Dovecot (1.0.7) I'm trying to figure out a way to convert the POP3 UIDLs (in cases where the courierpop3dsizelist is newer than dovecot-uidlist, at least) to something that Dovecot will read, or to configure Dovecot's pop3 to use a UIDL format that will work, as mentioned in the migration wiki. We have some "squeaky wheel" users who don't have their POP clients set to delete messages, and are likely to complain about re-downloading their several GB of mail. Thus far, the migration scripts haven't seemed to work properly, maybe because of the versions I'm using. I'm not sure whether the Courier versions there refer to Courier MTA version or Courier IMAP version, but adjusting the UIDL format to %v-%u (as suggested for early Courier 3 / Dovecot 1.0) hasn't worked (I saw %u-%v online, but that also didn't work). Since the Courier system doesn't seem to report validity, I also tried just '%u' - this works *if* I delete the header line as well as rename the courierpop3dsizelist to dovecot-uidlist, but I still don't get the exact same UIDLs as before. I'm willing to write my own migration tool, or to adapt the existing one, but I could use some assistance knowing how to do the translation. Dovecot -n for that instance is below, slightly sanitized, obviously I can change pop3_uidl_format; I also tried getting rid of pop3_reuse_xuidl: Basically, to give a concreate example, the Courier system seems to use the filename as the UIDL, with this courierpop3dsizelist: /2 45 1382654636 1199751891.13891_0.water-ox:2,Sa 2412 0:1382654636 1199927364.22870_0.fire-ox:2,S 2440 0:1382654636 1199936486.3332_0.wood-ox:2,Sa 2074 0:1382654636 1199985712.27745_0.water-ox:2,RS 4007 0:1382654636 1199993867.23139_0.fire-ox:2,S 1550 0:1382654636 producing this UIDL output: UIDL +OK 1 1199751891.13891_0.water-ox 2 1199927364.22870_0.fire-ox 3 1199936486.3332_0.wood-ox 4 1199985712.27745_0.water-ox 5 1199993867.23139_0.fire-ox [...] Dovecot's dovecot-uidlist: 3 V1199747645 N606 562 W2412 :1199751891.13891_0.water-ox:2,Sa 563 W2440 :1199927364.22870_0.fire-ox:2,S 564 W2074 :1199936486.3332_0.wood-ox:2,Sa 565 W4007 :1199985712.27745_0.water-ox:2,RS 566 W1550 :1199993867.23139_0.fire-ox:2,S producing: UIDL +OK 1 1199747645-562 2 1199747645-563 3 1199747645-564 4 1199747645-565 5 1199747645-566 (or, if I change the format to just %u): +OK 1 650 2 651 3 652 4 653 5 654 # dovecot --version 1.0.7 # 1.0.7: /etc/dovecot.d/XXX.cfg base_dir: /var/run/dovecot/pop-its syslog_facility: local4 protocols: pop3 pop3s listen: *:110 ssl_listen: *:995 ssl_ca_file: /etc/pki/dovecot/certs/XX.pem ssl_cert_file: /etc/pki/dovecot/certs/XXXX.pem ssl_key_file: /etc/pki/dovecot/private/XXXX.key disable_plaintext_auth: yes login_dir: /var/run/dovecot/pop-its/login login_executable: /usr/libexec/dovecot/pop3-login login_greeting_capability: yes login_processes_count: 4 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:/var/spool/maildir/%1Ln/%Ln:INDEX=/var/spool/dovecot/indexes/%1Ln/%Ln mail_debug: yes mmap_disable: yes maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_reuse_xuidl: yes pop3_uidl_format: %v-%u pop3_client_workarounds: outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: Mail. inbox: yes auth default: mechanisms: plain login passdb: driver: ldap args: /etc/dovecot.conf-ldap userdb: driver: static args: uid=vmail gid=mail home=/var/spool/maildir/%1Ln/%Ln socket: type: listen master: path: /var/run/dovecot/pop-its/auth-master mode: 384 user: vmail group: mail TIA! /wby

[Dovecot] Replication (Mac OS X)
by Rusty Ross 25 Oct '13

25 Oct '13

Hello, I am taking a stab at setting up dovecot replication between two OS X Mavericks servers. (The dovecot version in Mavericks is 2.2.5.) The first question I have is in regards to userdb. The user accounts are Open Directory based. The output of: doveadm user ‘*' …yields only: # doveadm user ‘*' submit However, specific user accounts can be looked up explicitly, ie: # doveadm user 'mary' field value uid 214 gid 6 home mail maildir:/Library/Server/Mail/Data/mail/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F quota maildir:User quota:noenforcing quota_rule *:storage=0 mail_location maildir:/Library/Server/Mail/Data/mail/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F sieve /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F/dovecot.sieve sieve_dir /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F sieve_storage /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F According to http://wiki2.dovecot.org/Replication, user listing via “doveadm user ‘*’” is required for replication. Any thoughts about how I can get that working (or work around it) in this environment? Thanks, Rusty

[Dovecot] dsync core dump

Dear all, We're slowly progressing towards migration, and now run into dscyn dumping core when trying to sync mailboxes from the old imap server. Needless to say that not one byte get's transferred. On the old.server all I see is a correct login. This is what we get for one example user: server:~# doveadm -v -D backup -R -u USER imapc: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib01_acl_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_quota_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so: undefined symbol: quota_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_zlib_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so: undefined symbol: i_stream_create_deflate (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(USER): Debug: auth input: USER system_groups_user=USER uid=XXXX gid=YYYY home=/home/USER /etc/dovecot/proxy-userdb doveadm(USER): Debug: Unknown userdb setting: plugin//etc/dovecot/proxy-userdb=yes doveadm(USER): Debug: Effective uid=XXXX, gid=YYYY, home=/home/USER doveadm(USER): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=yes, list=no, subscriptions=yes location=maildir:~/Maildir doveadm(USER): Debug: maildir++: root=/home/USER/Maildir, index=, control=, inbox=/home/USER/Maildir, alt= doveadm(USER): Debug: acl: initializing backend with data: vfile doveadm(USER): Debug: acl: acl username = USER doveadm(USER): Debug: acl: owner = 1 doveadm(USER): Debug: acl vfile: Global ACL directory: (none) doveadm(USER): Debug: Namespace : type=shared, prefix=shared/%u/, sep=, inbox=no, hidden=no, list=children, subscriptions=no location=maildir:%h/Maildir:INDEX=~/Maildir/shared/%u doveadm(USER): Debug: shared: root=/var/run/dovecot, index=, control=, inbox=, alt= doveadm(USER): Debug: acl: initializing backend with data: vfile doveadm(USER): Debug: acl: acl username = USER doveadm(USER): Debug: acl: owner = 0 doveadm(USER): Debug: acl vfile: Global ACL directory: (none) dsync(USER): Debug: Effective uid=XXXX, gid=YYYY, home=/home/USER dsync(USER): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=yes, list=no, subscriptions=yes location=imapc: dsync(USER): Debug: imapc: root=, index=, control=, inbox=, alt= dsync(USER): Debug: imapc(old.server:PORT): Looking up IP address dsync(USER): Debug: imapc(old.server:PORT): Connecting to IP dsync(USER): Debug: imapc(old.server:PORT): Starting SSL handshake dsync(USER): Debug: imapc(old.server:PORT): SSL handshake successful dsync(USER): Debug: imapc(old.server:PORT): Server capabilities: IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ MAILBOX-REFERRALS NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES IDLE AUTH=PLAIN ANNOTATEMORE dsync(USER): Debug: imapc(old.server:PORT): Authenticating as cyrus for user USER dsync(USER): Debug: imapc(old.server:PORT): Authenticated successfully dsync(USER): Debug: acl: initializing backend with data: vfile dsync(USER): Debug: acl: acl username = USER dsync(USER): Debug: acl: owner = 1 dsync(USER): Debug: acl vfile: Global ACL directory: (none) dsync(USER): Debug: Namespace : type=shared, prefix=shared/%u/, sep=, inbox=no, hidden=no, list=children, subscriptions=no location=maildir:%h/Maildir:INDEX=~/Maildir/shared/%u dsync(USER): Debug: shared: root=/var/run/dovecot, index=, control=, inbox=, alt= dsync(USER): Debug: acl: initializing backend with data: vfile dsync(USER): Debug: acl: acl username = USER dsync(USER): Debug: acl: owner = 0 dsync(USER): Debug: acl vfile: Global ACL directory: (none) Segmentation fault (core dumped) Here is the output of dovecot -n #
