Yeah, what he said. Someone helpfully added documentation on how to do this at the end of Dovecot1's wiki (http://wiki.dovecot.org/LDA/Sendmail) which probably should be copied to Dovecot 2's wiki. So that's what I did. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot %u variable problem....
by Kris 26 Apr '12

26 Apr '12

Hi guys n gals, im on an ubuntu 11 VPS on linode (dovecot version 2.013). ive spent a lot of time and googling trying to get postfix, dovecot, ssl, saslauthd and mysql to all play nice together and im quite close now but theres something going on i cant quite explain and id really appreciate some help. I have been going for ten hours on this today and it seems in direct conflict with what dovecot themselves say... the problem is a variable in dovecot (%u) which is normally used as a full username in sql query strings (i.e. user@domain) and is simply dropping the domain for some reason... From dovecot docs (http://wiki2.dovecot.org/Variables) The variables that work everywhere are: %u user full username (e.g. user@domain) so i have postfix and stuff set up ok to send at least and i know this because ive tested it by hard-coding the string in the sql query myself with a successful send... but, anyway, the problem with the '%u' variable is it is doing stuff like this: (from mail.log and mysql.log) localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): SELECT home,uid,gid FROM users WHERE id = 'admin(a)microhard.com' this was derived from the following query in /etc/dovecot/dovecot-sql.conf.ext user_query = SELECT home,uid,gid FROM users WHERE id = '%u' so no problem there.... but then this happens when i attempt to send mail and this means the user gets rejected because dovecot cant find the user id in the db without the correct string (i.e. user@domain): localhost dovecot: auth: Debug: sql(admin,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin' Query SELECT id as user, crypt as password FROM users WHERE id= 'admin' which is derived from the following query also in /etc/dovecot/dovecot-sql.conf.ext password_query = SELECT id as user, crypt as password FROM users WHERE id= '%u' and to further confuse me, this 'unchangeable' variable sometimes decides to right itself without any obvious reason... localhost dovecot: auth: Debug: sql(admin(a)microhard.com,xx.xx.xx.xx): query: SELECT id as user, crypt as password FROM users WHERE id= 'admin(a)microhard.com' im wondering if its something to do with my client dropping the domain, or whether dovecot has an error, or some other thing ive overlooked... my dovecot.conf looks a lot like this: # 2.0.13: dovecot.conf # OS: Linux 3.0.18-x86_64-linode24 x86_64 Ubuntu 11.10 ext3 first_valid_uid = 5000 last_valid_uid = 5000 login_greeting = I likes my ducks n geese I do. mail_location = maildir:/var/spool/mail/virtual/%u #enables logging all failed authentication attempts. auth_verbose=yes #enables all authentication debug logging (also enables auth_verbose). Passwords are logged as <hidden>. auth_debug=yes #does everything that auth_debug=yes does, but it also removes password hiding. auth_debug_passwords=yes #enables all kinds of mail related debug logging, such as showing where Dovecot is looking for mails. mail_debug=yes #enables logging SSL errors and warnings. Even without this setting if connection is closed because of an SSL error, the error is logged as the disconnection reason (v1.1+). verbose_ssl=yes passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile:/etc/dovecot/acls #quota = maildir:storage=10240:messages=1000 trash = /etc/dovecot/trash.conf } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = dovecot mode = 0660 user = dovecot } user = dovecot } ssl_ca = /etc/pki/dovecot/certs/ca-bundle.crt ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } userdb { driver = prefetch } userdb { driver = passwd } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { info_log_path = /var/log/dovecot-deliver.log log_path = /var/log/dovecot-deliver.log mail_plugins = quota postmaster_address = admin(a)microhard.com } any help *much* appreciated! cheerz Kris

[Dovecot] dsync: convert only mbox in /var/mail to maildir?
by Jeff Simmons 26 Apr '12

26 Apr '12

I'm migrating an old UW pop server to a new Dovecot server. The old server did not allow mail to be stored on the server, so only mbox files exist in /var/mail, with nothing in /home/$user. I'd like to copy the /var/mail directory over to the new server and then use dsync to convert the mbox files and put them in /home/$user/Maildir, but every permutation of the command line I've tried dies with a variation on can't find/write either /var/mail/mail or /home/$user/mail, seems it won't deal with mbox files without an associated mail directory. Can dsync be used for this kind of conversion, or should I look elsewhere for conversion utilities? Thanks for helping a noob who can't traverse a wiki without leaving a trail of breadcrumbs. -- Jeff Simmons jeff(a)j-simmons.net Simmons Consulting - Network Engineering, Administration, Security

[Dovecot] 2.1.x changes and dsync -- Wiki suggestion
by Jeff Kletsky 26 Apr '12

26 Apr '12

There are a couple things that show up on the Upgrading/2.1 wiki page that would be useful to have on pages describing dsync (Tools/Dsync, Migration/MailFormat, Tools, perhaps others): * dsync was merged into doveadm * You can't dsync 2.0.x to/from 2.1.x That second point is especially "interesting" to me as it seems that Apple MacOS X Server is still on 2.0.16, at least from what I see on opensource.apple.com. I was planning on migrating mail off the current server onto my friend's new MacMini, but I'll have to figure out how to "downgrade" the mail jail to a 2.0 version, it seems. Thanks for all the great work, Jeff

[Dovecot] Reading Mutt mboxes from Thunderbird
by Leonardo M. Ramé 26 Apr '12

26 Apr '12

Hi, I'm a user of Mutt, and before moving to Thunderbird I'm trying to share mboxes between them. To do this, I installed Dovecot to create an IMAP server in my local machine, to serve mutt mboxes to be read by Thunderbird. So far, I can read my inbox from /var/mail/%u, but in mutt, I have many folders in ~/mail, like 2010-mails, 2011-mails, mailing-list-x, mailing-list-y, and so on. How can I configure Dovecot to read them?. In /etc/dovecot/conf.d/10-mail.conf I have this: mail_location = mbox:~/Mail:INBOX=/var/mail/%u I'm using Ubuntu 11.10, and Dovecot 2.0.13.

[Dovecot] How to remove duplicate GUID messages from storage?
by Daniel Parthey 26 Apr '12

26 Apr '12

Hi, I tried to import messages like this: doveadm import -u username(a)example.org mdbox:/mail/dovecot/example.org/username/mail mbox:/root/mail.txt all This seemed to have imported the same messages in the mail storage, as they were already there. And now I have got a lot of duplicates. Then I deleted the mbox:/root/mail mail stuff from "mailboxes" folder and the storage remained, with duplicate GUIDs. The following command doveadm -v force-resync -u username(a)example.org INBOX outputs lots of messages like this one, with different GUID doveadm(username(a)example.org): Error: mdbox /mail/dovecot/example.org/username/mail/storage: Duplicate GUID 0b8a032d66a0924fb42c0000de5f8128 in m.55:45484041 and m.14:52173045 The messages at m.55:45484041 and m.14:52173045 have the same content, since they were seemingly imported from the mail store itself, they are in the storage twice now and require twice as much disk space as before. How can I manually remove these identical, duplicate messages from the storage to save space? Dovecot does not do it automatically. Kind regards, Daniel

[Dovecot] 2.1.5 problem with mail_location
by postmaster 25 Apr '12

25 Apr '12

I've been advised to set : mail_location = maildir:~/ as the home directory is found through a sql request. this has been working perfectly up to and including 2.1.4 from 2.1.5 however this setting gives cause to a problem : instead of looking in the mail home eg /var/mail/domain/user\@domain/ dovecot is looking for mail in /var/mail/domain/user\@domain/~ the '~' directory is created upon the first request for mail and all future mail transactions in dovecot is done relative to this folder. is this behavior a bug or a feature ??? -- Bjarne D Mathiesen København N ; Danmark ; Europa ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ denne besked er skrevet i et totalt M$-frit miljø MacOS X 10.7.3 Lion ; 2.8GHz Intel Core i7 ; 16GB 1067MHz DDR3
