[Dovecot] IMAP STARTTLS Problem
by Markus Fritz 05 May '12

05 May '12

Hello, I have this problem: May 5 21:02:35 opsys dovecot: imap-login: Disconnected (no auth attempts): rip=84.150.52.31, lip=78.46.216.126 Connecting via Thunderbird to STARTTLS won't work, but with a website from the same server it works for tls://opsys.de. So why is the port closed for external ip's? IPTABLES entry for imap is this: fail2ban-dovecot-pop3imap tcp -- anywhere anywhere multiport dports pop3,pop3s,imap2,imaps Key files are correct TLS is working from localhost. System is Debian squeeze -- Markus Fritz Administration opsys.de

[Dovecot] per user sieve after filters
by Andre Rodier 05 May '12

05 May '12

Hello, Thanks for dovecot, as it's still the best mail server. I'd like to use per users sieve_after scripts. Can I put in my dovecot config file, something like that: sieve_after = %h/Mails/Sieve/After/ It would be very useful for me, as I'd like to add vacation script to be executed from this place. Kind regards, André.

[Dovecot] Shared INBOX change in v2.1.6?
by Timo Sirainen 04 May '12

04 May '12

Previously Dovecot has shown shared INBOX like: * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/INBOX" * LIST (\HasNoChildren) "/" "shared/tss2/foo" The last change in hg makes it return simply (same as with Cyrus): * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/foo" This behavior could be made optional, but does anyone actually want it to work the old way (and why)? I'd rather not add an option that isn't useful to anyone. I think older Dovecot versions have allowed opening both shared/tss2 and shared/tss2/INBOX, but at least in v2.1 that code was broken. With the last change it's still possible to open both of them, the shared/tss2/INBOX just isn't visible in LIST output.

[Dovecot] dovecot sasl with postfix: SASL LOGIN authentication failed: Connection lost to authentication server
by David Jonas 04 May '12

04 May '12

When using dovecot (2.1.5) sasl with postfix (2.8.4) behind nginx smtp proxy I am seeing a ton of errors of the form: postfix/smtpd[7731]: warning: unknown[192.168.0.6]: SASL LOGIN authentication failed: Connection lost to authentication server Nothing is printed by dovecot in the logs regarding the error. It seems that dovecot just hung up on postfix. (side note: no, can't use xclient in nginx/postfix. But perhaps soon.) After much digging I thought I solved it with: login_trusted_networks = 172.20.20.0/24 mail_max_userip_connections = 0 This seems safe enough because dovecot is only providing sasl to postfix, no connections to the outside world. But the error is still happening. # doveadm penalty IP penalty last_penalty last_update 172.20.20.61 1 2012-04-30 19:15:56 19:15:56 strace on the anvil process shows a lot of GETs and INCs: 18:54:06 read(14, "PENALTY-GET\t172.20.20.61\n", 397) = 25 <0.000016> 18:54:06 write(14, "1 1335837245\n", 13) = 13 <0.000029> A two minute survey showed penalty distribution: 0: 60% 1: 15% 2: 18% 3: 8% Finally I just disabled penalties with the info from http://www.dovecot.org/list/dovecot/2011-December/062631.html and that seemed to do it. Is there a better way? This took me a long time to run down so I tried to make this message detailed enough that others with similar problems will stumble upon it.

[Dovecot] doveadm mailbox: rc=0 on error
by Andreas Schulze 04 May '12

04 May '12

Hi all, I use "doveadm mailbox mutf7 -7 $folder" to convert imap foldernames to UTF-8. If $foldername is not mUTF-7 encoded, doveadm returns "doveadm(root): Error: Mailbox name not valid mUTF-7: $folder" This errormessage is printed on stderr but the returncode of doveadm is zero. I tested with dovecot-2.0.* and dovecot-2.1.* # all right: $ doveadm mailbox mutf7 -7 'gr&APw-n'; echo $? grün 0 # also all right, no mUTF-7 encoded folder: $ doveadm mailbox mutf7 -7 'gruen'; echo $? gruen 0 # wrong $ doveadm mailbox mutf7 -7 'grün'; echo $? doveadm(root): Error: Mailbox name not valid mUTF-7: grün 0 Would be nice if doveadm exit with an errorcode != 0 in that case.

[Dovecot] Strange behaviour for sieve_before
by Simone Caruso 04 May '12

04 May '12

Hi all, i moved from dovecot 2.0.15 (lda) to 2.1.5 with lmtp transport, all works well with the same configuration directives. But sieve_before stopped working with mail_debug=no. The weird thing is that, with mail_debug=yes the sieve_before script starts working. Any idea?

[Dovecot] mdbox corruption
by Daniel L. Miller 02 May '12

02 May '12

I have isolated the corruption in a mailbox to 4 mdbox files. Two of these (smaller) files cause the force-resync to report a breakage and save the file as m.XX.broken. The other two (larger) files cause a crash. Is there a way I can fix these files and recover the mails? -- Daniel

[Dovecot] dovecot, ldap and multiple auth_bind_userdn
by Cédric Jeanneret 01 May '12

01 May '12

Hello List! I'm having some troubles for a client of mine: he has two ldap branches which may contain valid users for imap login... For now, dovecot is configured so that it uses the auth_bind: ======== uris = ldap://localhost:389/ auth_bind = yes auth_bind_userdn = uid=%u,ou=user,dc=org ldap_version = 3 base = dc=artemis user_attrs = user_global_uid = 8 user_global_gid = 8 pass_attrs = uid=user ## other options user_filter = (uid=%u) pass_filter = (uid=%u) default_pass_scheme = CRYPT ======== Unfortunately, I cannot manage to tell him "hey guy, uses those two branches": uid=%u,ou=user,dc=org and uid=%u,ou=external,dc=org Is there a special way to do that ? Is it even possible ? I cannot modify the ldap tree, so this option is out, unfortunately :(. My dovecot version: dovecot --version 1.2.15 Thanks in advance for your answers. Cheers, C.

Hi Timo my tests resulted in inheritance is given if a userfolder has set some acl to its new created subfolder , which is nice if some userfolder has its acl from global acl there is no inheritance to its new created subfolders, that subfolders will always created with full owner rights i am not really sure if its a good idea to have inheritance from global acl and if its hackabel what is your idea to this ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] restoring mails and directories
by oni-neko＠gmx.net 01 May '12

01 May '12

Good day! is there an easy way to restore e.g. deleted mails and/or mail directories? let me specify: I'm running dovecot 1.2.9 on a current ubuntu lts. It is set to Maildir and I backup the folder with the users maildata nightly via rsync. now, when someone deletes a mail that they still need, and I copy it back from the backup, it will not be visible to mail clients. When I change the mailfile by a letter or so, it shows. that's easy enough, if not exactly awesome ;-) But, if said person deletes a whole folder of mails, this way to make restored mails show up becomes rather unreasonable. surely there is a better way to do this? I'd be glad for any and all hints! =) best regards silvana -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Dovecot dsync mail replication issues
by Reuben Farrelly 01 May '12

01 May '12

Hi, I'm trying to set up some dsync based replication between two hosts on my network. The current topology is a single server running Postfix with a single dovecot installation with a Maildir per user (only 4 users including myself). No NFS, just local system users on ext4. I am only using system users, ie no virtual users. I am using dovecot deliver to deliver mails into the Maildir's. This - being a very standard Maildir installation - all works just fine. I'm running dovecot-2.1.5 (release versions) x86_64 with Gentoo on both hosts and using key based ssh to transport the data using the root login. What I would like to do is extend the design so as to replicate the Maildirs across a second machine and in the future be able to connect via IMAP into either machine to sync mail. Two way dsync would be rather cool because I could then deliver via SMTP to either system and have changes automagically propagate - but initially just simple replication would be a good start. I was hoping that dsync would allow me to do this, but I've run into quite a number of problems while getting this to work. http://dovecot.org/list/dovecot/2012-March/064243.html ...was very useful and I've based my config on that. Initially I've tried to sync up the user Maildirs, and this has more or less worked: doveadm sync -u lyn remote:root@dustbowl.reub.net This succeeds without error on the initial sync. However if I try to run the re-sync again (such as a use case of if the sync of another Maildir takes 4 hours so I want to resync up the earlier ones again) I end up with a mysteriously named INBOX folder in both the source and destination Maildirs: drwx------ 5 lyn lyn 4096 Apr 30 19:32 .INBOX_7a86a62d465a974fb92f00003b258734 It has the basic structure of a Maildir but is empty in terms of mails: drwx------ 2 lyn lyn 4096 Apr 30 19:32 cur -rw------- 1 lyn lyn 220 Apr 30 19:32 dovecot.index.log -rw------- 1 lyn lyn 51 Apr 30 19:32 dovecot-uidlist -rw------- 1 lyn lyn 0 Apr 30 19:32 maildirfolder drwx------ 2 lyn lyn 4096 Apr 30 19:32 new drwx------ 2 lyn lyn 4096 Apr 30 19:32 tmp First question: why is this random named directory being created in the origin Maildir? Shouldn't the replication be more or less read-only in the origin Maildir? Second question: If I re-attempt a doveadm sync a second time I get this error: tornado Maildir # doveadm sync -u lyn remote:root@dustbowl.reub.net dsync-local(lyn): Error: Can't rename mailbox INBOX_7a86a62d465a974fb92f00003b258734 to INBOX: Target mailbox already exists dsync-local(lyn): Error: Can't rename mailbox INBOX to INBOX_eb15f30ea563be4b703200002bd68bb1: Renaming INBOX isn't supported. tornado Maildir # It's not clear if the second attempt has failed or succeeded, and it's a bit odd that it errors out on a directory that the dovecot sync process itself has created. Third question: Upon starting Dovecot lots of ugliness is logged in the mail log: Apr 30 19:44:59 tornado dovecot: master: Dovecot v2.1.5 starting up (core dumps disabled) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: user mozsync: Initialization failed: Namespace '': mkdir(/var/www/xxx/server-full/Maildir) failed: Permission denied (euid=1016(mozsync) egid=1016(<unknown>) missing +w perm: /var/www/xxx/server-full, dir owned by 0:0 mode=0755) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: sync: User init failed Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Warning: I/O leak: 0x414190 (line 102, fd 16) Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: remote: doveadm(cisco): Fatal: User doesn't exist Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: read() from worker server failed: EOF Users mozsync and cisco are not valid mail users and it's not appropriate that Dovecot tries to create a Maildir for either of them. The users are system unprivileged users only, and do not ever send or receive mail. And - I/O leak? ;) Also, user cisco is local to one box only, and does not exist (nor does it need to) on the remote host. So any complaints about this user are invalid and dovecot needs to ignore replication for this user anyway. Fourth question, upon starting dovecot again, mail.log then spews several hundred of these messages: Apr 30 19:45:06 tornado dovecot: dsync-local(reuben): Error: msg-get failed: box=Trash uid=114863 guid=1335382569.M98089P29952.tornado,S=6479,W=6625 Before aborting entirely with: Apr 30 19:45:09 tornado dovecot: imap: Server shutting down. in=328 out=2042 It seems to me that a a few of those problems logged could be solved by being able to specify which system users to synchronise, rather than Dovecot making a blind assumption that all users actually have valid Maildirs that need to be created, and all need to be sync'd between two hosts. Subsequent delivery based sync'ing fails silently (pending more investigation) but I'd like to try and fix the above listed problems first before worrying about the later stages of the sync not working. Has anyone else run into these problems or found better ways of making this type of setup all work? Thanks, Reuben

[Dovecot] Refiltering mails without loosing flags
by Dieter Knopf 30 Apr '12

30 Apr '12

Hello, is there a way to refilter all mails in a folder without loosing all flags and moving all messages in a different folder? I have >10k mails in my Inbox and need to create new filterrules from time to time. But there is no way to refilter my inbox without moving. Atm i need to move all mails in a folder like "refilter" and then run getmail/... to refilter the mails. It would be really nice to refilter a existing folder and just move mails with hits in the filter list. Thanks Dieter

[Dovecot] setacl fails - does not find dovecot-acl file

Hi, I'm using dovecot 2.0.13 that ships with Ubuntu 11.10. I tried setting up a shared namespace as documented in the wiki to enable the sharing of a mailbox between two users. I have a Maildir(++) directory for each user. Each user has a system account. The Maildir of each user is owned by the user's system account and group read/writable by the group mail (hence mail_access_groups=mail). Relevant parts of my config: mail_plugins = acl mail_location = maildir:/home/dovecot/%u mail_access_groups = mail namespace { type = private separator = / prefix = inbox = yes hidden = no subscriptions = yes } namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/dovecot/%%u:INDEX=/home/dovecot/%u/shared/%%u subscriptions = no list = children } protocol imap { mail_plugins = $mail_plugins imap_acl } plugin { acl = vfile } plugin { acl_shared_dict = file:/home/dovecot/shared-mailboxes } When I try to create an ACL in a telnet session, the command fails with an internal error. The log shows: dovecot: imap(michael): Error: fstat(/home/dovecot/michael/.test/dovecot-acl.lock) failed: No such file or directory dovecot: imap(michael): Error: file_dotlock_open(/home/dovecot/michael/.test/dovecot-acl) failed: No such file or directory The error occurs whether a (manually created) dovecot-acl file exists or not. The dovecot-acl.lock file is created by not removed afterwards. Subsequent setacl commands will timeout waiting for the lock to be released until I delete it manually. If I create the dovecot-acl file manually and provide access to another user, the getacl command will correctly show the permissions and the other user can access the folder. setacl will still fail to modify the acl file, however (same error). Another thing that irritates me is that dovecot seems to use the dotlock locking method, although I explicitly set lock_method to fcntl (also tried flock, same behavior). I'm not using chroot. I appreciate any help to get this sorted out. Thanks, Michael
