[Dovecot] Migrating mail from mbox to maildir using dovecot
by Donny Brooks 15 Sep '10

15 Sep '10

Hello, Currently our mail server is setup to use postfix and dovecot, which is fine except it is setup to use mbox format mail. That and procmail as we need to move to sieve but that is a different issue. I have searched until blue in the face and cannot find a 100% working solution that doesn't require alot of manual interaction to move the mail boxes from mbox to maildir. I have tried the mb2md.pl stuff but with over 150+ users that can get tedious having to log in as each one of them to migrate them. I also tried the convert plugin located here: http://wiki.dovecot.org/Plugins/Convert but it kept erroring about not able to convert the box and exiting. We have approx 200GB of mail total that needs to be migrated. Maybe I am just simply missing something but is there a way that we can migrate all the users with minimal end user interaction and minimal administration time? We need this done asap as our backups are killing us with the large mbox style files. Thanks in advance for any and all input to this. -- Donny B.

[Dovecot] Authentication with lower case username ONLY
by Leander S. 15 Sep '10

15 Sep '10

Hi, how do you guys force your users to authenticate with lower case letters ONLY? Or convert it? Is there a SASL Option to force that - or are you using scripts i.e. a bash script in combination with the command "tr" ... or a third solution I didn't think of yet? I'm using Postfix / Dovecot combination. Postfix is told to use Dovecots SASL Service to authenticate it's users. For my outgoing eMails I already wrote a script with tr which forms upercase usernames to lowercase ones ... but it's not enough. SpamAssassin is still confused and writes uppercase letters in it's Database etc. ... So that's why I'm looking for a more universal solution. P.S. I would basically prefer a convertation - but I would also be fine with a forced lower case auth system. Thanks & Regards

[Dovecot] v2.0.0 released
by Timo Sirainen 15 Sep '10

15 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.0.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.0.tar.gz.sig As promised last Friday, here's the v2.0.0 release finally. I'm cautiously optimistic that v2.0.1 won't (have to) be released for a few weeks, since there was quite a lot of testing and fixing going on in the RC stage. Remember to read http://wiki2.dovecot.org/Upgrading/2.0 before upgrading from v1.x. Although there is automatic config conversion, it can't handle everything, so reserve some extra time for upgrading. If you find an upgrade problem that isn't listed on the wiki page, please add it there or email Dovecot mailing list about it. Pigeonhole Sieve and ManageSieve support can now be installed without patching Dovecot. Unfortunately there isn't a Pigeonhole release yet for v2.0, but its Mercurial code tree should be quite stable. See http://wiki2.dovecot.org/Pigeonhole There are no changes since v2.0.rc6. The largest changes since v1.2 are: * Dovecot uses two system users for internal purposes now by default: dovenull and dovecot. You need to create the dovenull user or change default_login_user setting. * Global ACLs are now looked up using namespace prefixes. For example if you previously had INBOX. namespace prefix and a global ACL for "INBOX.Sent", it's now looked up from "INBOX.Sent" file instead of "Sent" as before. * Maildir: File permissions are no longer based on dovecot-shared file, but the mailbox directory. + Redesigned master process. It's now more modular and there is less code running as root. + Configuration supports now per-local/remote ip/network settings. + dsync utility does a two-way mailbox synchronization. + LMTP server and proxying. + Added mdbox (multi-dbox) mail storage backend. + doveadm utility can be used to do all kinds of administration functions. Old dovecotpw and *view utilities now exist in its subcommands. + imap and pop3 processes can now handle multiple connections. + IMAP: COMPRESS=DEFLATE is supported by imap_zlib plugin + director service helps NFS installations to redirect users always to same server to avoid corruption

[Dovecot] sieve is broken in the latest revision
by interfaSys sàrl 15 Sep '10

15 Sep '10

All the sudden messages filtered by sieve are delivered to folders named after the recipient instead of sticking to the rules and delivering the messages to the INBOX. Is this an intended change? Instead of Maildir/.INBOX it goes to Maildir/.user(a)domain.com Cheers, Olivier

[Dovecot] Dsync error, Targer mailbox already exists
by Henrique Fernandes 14 Sep '10

14 Sep '10

Hey, why i am getting this error ? dsync(user(a)example.com): Error: Can't rename mailbox VoIP_08300a224c41694c0d0f000020ce4ec5 to VoIP: Target mailbox already exists It happens when i run dsync twice, but it should do only changes right ? dovecot 2.0 I am traying to convert all my user mboc to maildir so i made an script to help. The enveriment: Have dovecot looking into file conf and in mysql. Mysql over rides file conf. in file have mail_location mbox:path:INBOX:path2 so i run this comand: dsync -v -u user(a)domain.com mirror maildir:~/mail/ I run this command to all user in my server, about 8000 After the first dsync it will take a while, but dovecot is still running and looking at mail_location to mbox. So now, i run again dsync, but now i thought it would do only changes, email that arrived while i was converting, but is not doing this and i am getting that stuff, so i get duplicated mailbox. Anyway, my ideia after this second sync that should be much faster i would change in mysql to mail_location maildir:~/mail/ And from now on this user would receive mail to maildir location, and i would run now the dsync but now reversed. like this: dsync -v -u user(a)domain.com mirror mbox:/pathl:INBOX=path And it should be working now right ? Without any down time ? Does any one have a better ideia about how to sync this mails without down time ? Thanks for all! But the bigs quest here is about the error: dsync(user(a)example.com): Error: Can't rename mailbox VoIP_08300a224c41694c0d0f000020ce4ec5 to VoIP: Target mailbox already exists Any one ? []'sf.rique

[Dovecot] quota dict play nice with existing tables
by Miha Vrhovnik 14 Sep '10

14 Sep '10

Hi, I'm trying to set Dovecot 2.0 with postgresql dict. It's kind of working but not as I'd like to. Dovecot expects to get a dedicated table for quota management. When I've run *doveadm quota recalc -A* I've noticed in the logs that Dovecot tries to run DELETE statements. Fortunately it didn't succeed as I've only given it SELECT and UPDATE permissions on the fields that it needs. I'd like to configure it, in UPDATE only mode as rows already exist and there is no need to issue any other statement. Regards, Miha -- It's time to get rid of your current e-mail client ... ... and start using si.Mail. It's small & free. ( http://www.simail.si/ )

[Dovecot] need help with shared mailboxes
by alex 14 Sep '10

14 Sep '10

I have some problems with setting shared mailboxes . I use dovecot 1.2.11 with following namespaces : mail_location: maildir:~ namespace: type: private separator: . inbox: yes list: yes subscriptions: yes namespace: type: private separator: . prefix: INBOX. hidden: yes list: no subscriptions: yes namespace: type: shared separator: . prefix: shared.%%n. location: maildir:/home/sites/%d/mail/%%n/Maildir/ list: children plugin: acl: vfile acl_shared_dict: proxy::acl dict: acl: mysql:/usr/local/etc/dovecot-share-sql.conf In the private namespace I use to have only INBOX. space because I have migrate from courier and I ahave problemes with duplicate folders. The disk structure looks like : /home/sites/domain.tld/mail/user(withoutdomain)/Maildir What I'am trying to do is to give access to a user (user2(a)domain.tld) some other user mailbox (user1(a)domain.tld) in the /home/sites/domain.tld/mail/user1/Maildir I have created a file dovecot-acl with : owner lrwstipekxa user=user2(a)domain.tld rl - in the dovecot-share-sql.conf I have : connect = host=/var/lib/mysql/mysql.sock dbname=xxxx user=xxx password=postfixpass map { pattern = shared/shared-boxes/user/$to/$from table = user_shares value_field = dummy fields { from_user = $from to_user = $to } } and in the user_share table : +-------------------+------------------+-------+ | from_user | to_user | dummy | +-------------------+------------------+-------+ | user1(a)myhost.ro | user2(a)domain.tld | 1 | | user1 | user2 | 1 | +-------------------+------------------+-------+ (not sure what I need %n or %u) Now , in TB under the user2 , if I check subscribe , under the shared, I have a INBOX folder that is always check but nothing else. From what I understand I suppose to see user1 folders and I think it is something wrong with my config (namespaces, paths). If someone have succeeded to configure dovecot with shared mailboxes and namespaces that use . as separator please help me. Alex.
