[Dovecot] Dovecot+LDAP lda problem
by Zeljko Culek 10 Dec '13

10 Dec '13

Hello everyone, I need some help with Dovecot+LDAP config and local delivery. We're using Dovecot 2.0.9 on Centos 6.4. Before, we used Qmail with the same LDAP. Our LDAP accounts have the attribute deliveryMode which we used for mailing lists (OK, they are in fact mailing groups rather than lists). When the attribute is set to deliveryMode = nolocal Qmail did not deliver mail to the list mailbox, only to the accounts on the list/group. Now with Dovecot(+postfix) I can't achieve the same behaviour. Can Dovecot be set up not to deliver the mail to the list mailbox if the list has the attribute deliveryMode = nolocal? This is my /etc/dovecot/conf.d/dovecot-ldap.conf.ext hosts = xxx.xxx.xxx.xxx auth_bind = yes dn = cn=admin,dc=nth,dc=ch dnpass = xxxxxxxxxx ldap_version = 3 base = dc=nth,dc=ch #deref = always scope = subtree user_attrs = mail=user user_filter = (|(&(objectclass=inetOrgPerson)(mail=%u))(|(mailAlternateAddress=%u))) pass_attrs = uid=user pass_filter = (&(objectclass=inetOrgPerson)(|(mail=%u)(mailAlternateAddress=%u))) default_pass_scheme = CRYPT Basicaly, I want to make check: if deliveryMode=nolocal > do not deliver to mail=some.mail(a)tld.com (only to mailForwardingAddress) else deliver normally :) Thnx, Zeljko

[Dovecot] Index issue?
by IT geek 31 10 Dec '13

10 Dec '13

I've just hastily migrated from Dovecot 1.2.9 to 2.2.9 due to a disk crash. When I say hastily, I literally copied the user's mail data files to the new server and then started the Dovecot service. The trouble is, I now have a user who can see all the subfolders of her inbox in Outlook, but not on her iPad. Do I need to re-index her mail folders? The data is there (as seen by Outlook 2013) and is good, but the iPad mail client only sees the top-level folder. Any thoughts? -Mark

[Dovecot] Problem with INDEXes and deleting shared folders
by Achim Gottinger 10 Dec '13

10 Dec '13

Hi, I use dovecot 2.1.7 on debian wheezy. I have a bunch of shared folders whom i configured to store the indexe's under the users mail_location/shared/%%u. I configured acl's for those shared folders in an way that all users should be able to add and delete folders (for example "group=buchhaltung keilrwtsx"). Creating folders works fine but if i try to delete such an folder i get the following error. Dec 10 12:03:41 logon-zor dovecot: imap(ag): Debug: Can't rename 'shared/buchhaltung/Test' to 'Trash/Test': one namespace has index dir and another doesn't Of course there is no dovecot.index file in /home/vmail/buchhaltung/mai/.Test but there is one in /home/ag/vmail/mail/shared/buchhaltung/.Test and in /home/ag/vmail/mail/.Trash. Seems dovecot does not honour the shared namespaces index settings when trying to rename that folder. Is there an fix for this issue in 2.1.7 or would upgrade to 2.2.5 (from debian unstable) help? Thanks in advance Achim Gottinger Here are my namespace mail_location etc. settings: mail_home = /home/vmail/%u mail_location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX mail_uid = 998 mail_gid = 998 first_valid_uid = 998 first_valid_gid = 998 mail_shared_explicit_inbox = yes maildir_very_dirty_syncs = yes namespace { list = children location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { inbox = yes location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX prefix = separator = / type = private }

[Dovecot] Question regarding quotas (is this a bug or intended behavior) ?
by Gilles Chauvin 09 Dec '13

09 Dec '13

Hi, I was wondering if this is a normal behavior (test was made using Dovecot v2.2.9). In my config, quotas are configured as follows: plugin { quota = dict:Userquota::file:%h/dovecot-quota quota_rule = *:storage=1G quota_rule2 = Trash:ignore } # doveadm mailbox status -u my_user "messages vsize" '*' Trash messages=4997 vsize=229535631 Drafts messages=0 vsize=0 Sent messages=0 vsize=0 Junk messages=0 vsize=0 INBOX messages=0 vsize=0 # doveadm -f flow quota get -u my_user Quota name=Userquota Type=STORAGE Value=0 Limit=1048576 %=0 Quota name=Userquota Type=MESSAGE Value=0 Limit=- %=0 The 4997 mails in the Trash mailbox are ignored as desired, but now, if I have the following case: # doveadm mailbox status -u my_user "messages vsize" '*' Trash messages=0 vsize=0 Trash/TEST messages=4997 vsize=229535631 Drafts messages=0 vsize=0 Sent messages=0 vsize=0 Junk messages=0 vsize=0 INBOX messages=0 vsize=0 (As you can see mails were moved to a Trash/TEST mailbox) # doveadm -f flow quota get -u my_user Quota name=Userquota Type=STORAGE Value=220918 Limit=1048576 %=21 Quota name=Userquota Type=MESSAGE Value=4997 Limit=- %=0 I tried to add the following quota_rule: quota_rule3 = Trash/*:ignore But this doesn't fix anything. Do you have any idea about why this is not working ? Thanks, Regards, Gilles.

[Dovecot] Use Replication plugin to do a backup (one-direction sync)
by Francesco Barresi 09 Dec '13

09 Dec '13

Hello, I have a setup where I need to have Server A (dovecot 2.1.7) replicated on a Server B (dovecot 2.1.7). I know that I can do a per user backup with: doveadm -D backup -u %u remote:mailmirror@serverB I would like to use Notify/Replication to backup only when there's something new. I don't understad if the Replication plugin can be used to do a backup server, or it's only of for two-way sync? My question is: It's possible to use Replication to do a backup (one-direction sync)? Thanks Francesco

[Dovecot] Expire plugin - empty expires table

Hello, Dovecot does not fill expires table when moving messages to Trash or Junk folder.

[Dovecot] [PATCH] lib-sql/driver-mysql.c - Add support for enabling MYSQL_OPT_SSL_VERIFY_SERVER_CERT
by Gareth Palmer 09 Dec '13

09 Dec '13

Hello, The following patch adds support for enabling MYSQL_OPT_SSL_VERIFY_SERVER_CERT. It makes the mysql client library check that the commonName in the server's SSL certificate matches the host name provided to mysql_real_connect() and aborts the connection if the name doesn't match. An example connect string would look something like: connect = ... ssl-ca=/path/to/ca.cert ssl-verify-server-cert=yes By default the mysql client library does not perform this check.

[Dovecot] dovecot.index-Errors with multiple IMAP client access in Dovecot 2.2
by Martin Rabl 08 Dec '13

08 Dec '13

Hello list, I hope you can help me! My self-compiled dovecot 2.2.6 (and the two minor versions before, too) throws that errors: Nov 28 18:29:00 mailserv dovecot: imap(martin(a)example.com): Error: Transaction log /srv/vmail/example.com/martin/Maildir/dovecot.index.log: duplicate transaction log sequence (25) Nov 28 18:29:00 mailserv dovecot: imap(martin(a)example.com): Error: /srv/vmail/example.com/martin/Maildir/dovecot.index log position went backwards (24,40 < 25,10028) ... and so on ... duplicate transaction log sequences and backwards gone log positions, and this always, when I use at least two IMAP clients at the same time (better: the two clients are online and logged in at the same time). That happens only with one user (me ;-) ), the other about 15 users on this server are having no problems. What I see: the clients are bothering each other, but I don't know, why. I thought about the used reiserfs filesystem on the server, but there were no problems with 1.2 on the same server. Some words about my client setup: I use Thunderbird and iPhone at the same time, and as a third client on the same Server there is a Thunderbird instance at my company, which runs parallel to the other two. Seems to be weired, but isn't really (IMHO ;-) ). Sometimes there are two TBs at the same mailbox, sometimes only the iPhone and a TB, sometimes all three. This runs quite good for long time with dovecot 1.2 and 2.1.x (the last one at my company in a similary setup with more users and several clients at the same time).

[Dovecot] shared folder - ACL
by Héctor Moreno Blanco 08 Dec '13

08 Dec '13

Hello everyone, I've trying to configure shared folders in dovecot 2.1.6 without success. My configuration is: mail_plugins = quota autocreate mail_log notify acl ... plugin { ... acl_shared_dict = file:/etc/dovecot/shared-mailboxes.db ... } Protocol imap { ... mail_plugins = imap_quota imap_acl ... } When I try to set acl to a folder: a02 setacl inbox.test1 user1 lr a02 BAD Error in IMAP command SETACL: ACLs disabled. In the logs, I can see: dovecot: imap(testing_ddfr): Debug: acl: No acl setting - ACLs are disabled What am I missing? Thank you very much in advanced. Kind regards. Héctor Moreno Blanco.

[Dovecot] imap list response has an extra field on some mailboxes.
by Kui Zhang 08 Dec '13

08 Dec '13

Hello, per rfc3501 7.2.2. LIST Response Contents: name attributes hierarchy delimiter name Dovecot: 2.1.16 /usr/lib/dovecot/imap -u user(a)domain.tld list "" "*" Most responses are correct. But some appears to not be. """ * LIST (\HasNoChildren) "/" {117} path/to/"part_mailbox_name" other_parts * LIST (\HasNoChildren) "/" {10} "test" box """ char after {117} appears to be \n. All affected mailboxes appears to have ' " ' in mailbox name. And the number between '{' '}' appears to be the length of the path. Anyone ran into this issues before? If so, how to fix it? Is it a bug? Other rfc I should read? Thanks Kui.Z

[Dovecot] Dovecot readable compressed mail archive
by Dave Hall 08 Dec '13

08 Dec '13

Hello. Is Dovecot able to create and/or read any sort of compressed mail archive? We have a large installation with a few users who need to keep a large amount of email available. With maildir this means a large number of individual files, leading to additional load on our backup process. Even using a compressed mbox file as an archive would help, but only if Dovecot is able to interact with this file seamlessly while keeping current email in the maildir format. Please pardon if this is old business, but I haven't been able to find any reference to it by searching. Thanks. -Dave -- Dave Hall System Administrator Computer Science Binghamton University davehall(a)cs.binghamton.edu 607-760-2328 (Cell) 607-777-4641 (Office)

Re: [Dovecot] zlib config questions
by Richard Platel 08 Dec '13

08 Dec '13

You only need to add the zlib plugin to mail_plugins once. As far as I know, there's no indication in the logs that mail is being compressed, and the filename isn't modified to indicate that it's compressed, but, of course, the files are zlib data on disk. One gotcha if you're using maildir is, if you're planning to compress old mail, make sure that the S= and W= sizes in the filenames are correct, otherwise dovecot errors and closes the client session, and it can't repair the filename on it's own.

[Dovecot] delete message with specified id
by Костырев Александр Алексеевич 08 Dec '13

08 Dec '13

Good day, everyone! Could someone help me to find a way to delete message with certain id from all users's mailboxes? What seems to be a problem: I have configured exim + dovecot lmtp I got a long list of aliases in BD in form of: +----------+-------------------------------------+ |alias_name recipients | (for example) -----------|-------------------------------------+ | list_a | user1@example.org,user2@example.org | +----------|-------------------------------------+ When I send a message to that list_a, user1 and user2 get the mail and I see this in log: Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user1(a)example.org) copy from INBOX: box=INBOX, uid=1, msgid=<E1VojxY-0004Gl-Gu@beta-mail>, size=570 Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user1(a)example.org) oCOXKmAkoVIjQAAA635u4w: msgid=<E1VojxY-0004Gl-Gu@beta-mail>: from=root@beta-mail: subj=: saved mail to INBOX Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user2(a)example.org) copy from INBOX: box=INBOX, uid=1, msgid=<E1VojxY-0004Gl-Gu@beta-mail>, size=570 Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user2(a)example.org) oCOXKmAkoVIjQAAA635u4w: msgid=<E1VojxY-0004Gl-Gu@beta-mail>: from=root@beta-mail: subj=: saved mail to INBOX Is it possible to delete these letters with known msgid=<E1VojxY-0004Gl-Gu@beta-mail> from all users mailboxes with couple of simple commands ? How do I do it currently: in exim's log I get mailaddress of a user, get into his mailbox (wich cd), find the letter I need, with ls -i I get inode, search (with find) through all users mails and delete all files with that inode, then I have to rebuild dovecot indexes with doveadm mailbox status -A -t all INBOX -- С уважением, Костырев Александр администратор Linux-систем

[Dovecot] pigeonhole openssl s_client
by LEVAI Daniel 08 Dec '13

08 Dec '13

Hi! I'm trying to get information about a server certificate from a pigeonhole sieve server. Various connection attempts show only "wrong version number" or "unknown protocol" errors from openssl: $ openssl s_client -connect example.com:4190 { -tls1, -tls1_1, -tls1_2 } [ -starttls { imap, pop3 } ] None of these work. I'm trying to see who signed the server cert. How could I do this? Thanks, Daniel -- LÉVAI Dániel PGP key ID = 0x83B63A8F Key fingerprint = DBEC C66B A47A DFA2 792D 650C C69B BE4C 83B6 3A8F

[Dovecot] Replication via sneakernet
by David Bishop 07 Dec '13

07 Dec '13

Is there a way to get a running transaction log from a Dovecot instance to synchronize (and I use that word very, very loosely) multiple instances that don't share a network? Why I would want to do such a thing: I have a couple way stations along a long, winding road through very hilly country, and at each of these stations, I have a few people (and many, many more at one end of the road). Which people are where varies from hour to hour (but they're all members of a known, larger, group of people with accounts). It would be helpful to get communication (however limited) along this road (and establishing direct communication, either through radio or landline, is not feasible within the budget constraints I have), and it is possible to store a complete copy of the mail spool to a small box at each station (the total mail spool over the period I care about is in the tens of megs). There are trams shuttling back and forth along this road (stopping at each station), and adding a small box (such as a weatherproofed Raspberry Pi with a wifi dongle) to transport files up and down the road is pretty simple. Doing incremental copies of the mail spool is also simple, keeping track of files that get moved or deleted is a bit harder (but still not that bad), but I have no idea how hard it is to track what messages have been seen, especially for the shared folders (which we use instead of mailing lists). I realize this is not a "normal" use of Dovecot, but given this, does anyone who knows the software (and how it keeps track of messages) better have suggestions on how to approach the problem?

[Dovecot] Easy migration from Dovecot 1.2.16 ppc maildir to 2.1.17 amd64 mdbox
by Philippe Lelédy 07 Dec '13

07 Dec '13

Hi After http://retrospekt.dk/2011/08/migrating-maildir-to-dovecot-2-0-dbox/ I used a two phases process. The first, transfering over the network, is done by this shell function, on the *new* server. The argument is the <user> fetchOldServer () { rsync -poazuHK --exclude="**/dovecot.index*" \ -e ssh root@oldServer:/var/mail/Maildirs/$1 /var/mail/oldServer/ } I had to add --exclude="**/dovecot.index*" because of a change of endianness (ppc -> amd64). the second, having dovecot import the folder, is done by this second fonction dsync () { doveadm backup -R -u $1(a)mondomaine.fr maildir:/var/mail/oldServer/$1 } this one is really fast. Both in one function doveImport() { fetchOldServer $1 && dsync $1 } I tried for initial load to empty mailbox. I am not sure it will works on a non empty mailbox. But would be nice, as it would allow a fast last minute sync before switch, minimizing downtime. Ph. Le
