[Dovecot] shared mailboxes question
by Cory Coager 01 Oct '07

01 Oct '07

I'm using a virtual mailbox setup. Lets say my users have mailboxes in /home/vmail/domain/%u. What I'm trying to do is setup one namespace that points to /home/vmail/domain and contains everyones mailboxes that I can subscribe to. Is this possible? I tried using a symlink to /home/vmail/domain but it doesn't work because its looking for the dotFoldername. The only way I could get this to work is by creating a symlink for each folder in every mailbox. This is way too much maintenance especially since it will dynamically change. The only other way I could get it working was to create a namespace for each user and point to /home/vmail/domain/%u/Maildir/. Then inside everyones Maildir/ create a symlink for INBOX -> . This works but I'd have to do it for each user when I'd rather just use one namespace. Is there an easier way of doing this?

[Dovecot] Opinions on preferred namespace?
by Ed W 01 Oct '07

01 Oct '07

Hi Any opinions on a preferred namespace setting for use with Dovecot? Deciding factors seem to be client support, not being too unusual, accidental ease of setup, wider character range support (eg dots in folder names?), issues when scripting imap commands? For example Outlook Express (common with our userbase) seems to assume no folderprefix when using our current Courier server and from memory I think this causes some subtle issue with Sent Items and Drafts folders until you tell it to use an INBOX. folder prefix? (can't recall the exact details right now) I notice also that Thunderbird will show all folders under "Inbox" if I have an INBOX. prefix, but shows them all in a list if there is not one. Actually I find the former quite a useful feature because I have a number of test accounts where I only want to click into the INBOX, do I can keep the list of folders closed up Any other programs exhibit any (possibly beneficial) side effects from different prefix choices? Anyone got any preferences either way? Any pros/cons in using a dot as folder separator rather than a slash? I can see some logic in using an INBOX folder prefix and a slash as the folder separator because this would then mimic the on-disk layout.. (Is this what cyrus does?) I mainly care about best support for Outlook Express / Windows Mail and Thunderbird - any opinions on most compatible settings? Cheers Ed W

Correct. If the folder does not exist, maildrop will create it on first delivery. If the end user deletes the folder, maildrop will recreate the folder on the next message delivery to that account.

[Dovecot] 1.1b1 initial pop3 login: assertion failed
by David Jonas 01 Oct '07

01 Oct '07

Currently running 1.0.2 with 1.1b1 listening on a different port. On first pop3 login on 1.1b1 I received an immediate disconnect (I was testing with telnet) with the log entries below. Subsequent logins work fine. Other accounts that I tried did not have the same problem. So this is probably isolated to some bad indexes or something, but I thought I should let Timo know.

Does ACL's apply to all subfolders? For instance, if I create a dovecot-acl in a Maildir/, does it apply only to the INBOX or does it apply to all subfolders as well?

[Dovecot] v1.1.beta2 - maildir quota calculation problem
by Andrew Pavlenko 01 Oct '07

01 Oct '07

I have a problem with the maildir quota plugin. Any imap operations cause the plugin to recalculate the mailbox size and put the new value in the second line of the maildirsize file, while the third line always contains the size of the latest operation. So the resulting sum is incorrect. Moreover, quota-warning is not working either. Have anybody else met such problem? mail# ./dovecot -n # 1.1.beta2: /usr/local/etc/dovecot.conf ... mail_plugins(default): quota mail_log mail_plugins(imap): quota mail_log mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 ... plugin: quota: maildir quota_rule: *:storage=10240 quota_warning: storage=75%% /usr/local/etc/quota-warning.sh 75

[Dovecot] Mixed Courier POP3 and Dovecot IMAP environment
by Jan van den Berg 01 Oct '07

01 Oct '07

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be able to use Dovecot IMAP: - I have to use the namespace prefix in the dovecot.conf file: I read this in the wiki. - "Patch" the source so Dovecot IMAP will look for/use 'courierimapuiddb' instead of 'dovecot-uidlist': otherwise I guess POP3 and IMAP users will have different UID files, right? Is this smart or will this still break the UID file? - "Patch" the source so Dovecot IMAP will look for/use 'courierimapsubscribed' instead of 'subscriptions' of should I just go with the renaming of the files? I'm thinking about patching so the transition can be as transparent as possible: Also if anything might go wrong in production I want to be able to switch back to the 'old' Courier IMAP (without renaming files etc.) Any thoughts on this? Cheers, Jan

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz.sig Several bug/crashfixes. deliver now supports -a parameter (see http://wiki.dovecot.org/LDA) which allows Sieve plugin v1.1.2 to use envelope :detail "to" checks. I also did one more API change for mailbox_transaction_commit*(). There's probably something still wrong with SORT command, but other than that I've fixed everything that's been reported.

[Dovecot] Maildir ignore

Hello there. I do like Dovecot so far, but ran into problem I cant seem to solve, maybe someone can point me into right direction please. I am running version 1.0.rc15 on CentOS 5 Linux i386 system, ext3 fs. The problem is I cant get the maildir: and :ignore to work together. Here is my SQL query, that includes the Quota field. # cat /etc/dovecot-sql.conf | grep -i quota user_query = SELECT maildir AS home, 901 AS uid, 901 AS gid, CONCAT('maildir:storage=', floor(IF(quota!=0, quota,-1)/1000), ':ignore=Trash') AS quota FROM mailbox WHERE username = '%u' AND active = '1' Even Dovecot agrees it seems correct. # cat /var/log/maillog | grep kaktus | grep quota\= | tail -n1 Sep 30 23:37:33 XXXXXX dovecot: auth(default): master out: USER 5 XXX(a)XXX.cz home=XXX uid=901 gid=901 quota=maildir:storage=1024:ignore=Trash I hope this is the correct way. Looking at IMAP communication with Wireshark, the server seems to ignore my settings. 118 uid copy 22 Trash\r\n 118 NO Quota exceeded\r\n Anyone can help me, please ?

[Dovecot] dovecot-dspam plugin & virtual users
by Wicher Minnaard 30 Sep '07

30 Sep '07

Hi list, hi Johannes, I'm trying to use the dovecot-dspam plugin ( http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration ) with vpopmail's virtual users. All seems well, except for the fact that dspam should be called with '--user currentuser(a)currentdomain.com' at line 157 here: http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration/beta7-c… For my needs, 'currentuser@currentdomain' could be taken as the login name I use for logging in to Dovecot. As I'm not a C-programmer by a long shot, I was wondering if one of you could help me use the bincimap-API to import the login name into a variable so I can use that variable to construct a suitable dspam-command. Hope this is possible! Regards, Wicher Minnaard

Hi, I've found the dovecot dspam plugin and looked at the code. I forks and calls the dspam binary for every mail. I didn't like this behavior, so I've migrated it to use libdspam.

Comments and patches are welcome ;) http://www.cynapses.org/tmp/dovecot-dspam-plugin-0.1.tar.gz Cheers, -- andreas -- http://www.cynapses.org/ - cybernetic synapses

[Dovecot] Log file name too with mail_log

Hi! Is there a way to log the file that have been copied when a person move it from a folder to another using mail_log? Actualy this is what I get in logfile: dovecot: 2007-09-27 15:15:33 Info: IMAP(user(a)mydomain.com): copy -> Spam: uid=101, msgid=<46FBC6C9.1060301(a)somedomain.com>, box=Dovecot What I would like to have is something like: dovecot: 2007-09-27 15:15:33 Info: IMAP(catunda(a)mydomain.com): copy -> Spam: uid=101, file=/cur/1190916950.P15981Q38M976125.mydomain.com:2,S, box=Dovecot I believe that its a pretty simple thing to do, but my C skills are null! Any help would be great. Thankz! !DSPAM:46fc21ce213771244520847!

[Dovecot] Subaddress Extension in sieve plugin
by Frank Behrens 30 Sep '07

30 Sep '07

Hello! With many MTAs it is possible to use a special form of adressing: subaddresses or "plussed addresses". For sendmail you can read some information on http://www.sendmail.org/m4/misc_features.html http://www.unix.org.ua/orelly/networking/sendmail/ch24_04.htm#SML2-CH-24-SE… In a sieve filter you can analyse these special detail values, the syntax is described in RFC3598 (http://tools.ietf.org/html/rfc3598) The current deliver with sieve plugin for dovecot seems to support this RFC, but has the detail information not available. If I use require ["subaddress", "fileinto", "reject"]; require "envelope"; if envelope :detail "to" "junk" { fileinto "junk"; } the rule is not triggered, because the detail information from envelope is not available. Deliver gets the user information only via command line switch "-d". I did not analyse the problem very deep, but I believe we should introduce a new command line parameter for deliver, so deliver can pass the detail information to the sieve plugin. With that parameter you are able to pass the detail information from sendmail to devecot's deliver in the same way procmail is handled (procmail uses -a parameter). To avoid confusion: deliver has already a parameter -m to specify a different mailbox. In the described case the mailbox should be determined by the sieve filter, not via command line parameter. Existing workaround: Because I need this functionality I wrote a quick (and dirty?) workaround. Sendmail does not call deliver directly, but a wrapper program, that adds an additional "Delivered-To" header line. So the detail information may be processed with if address :detail ["Delivered-to"] "junk" { but I would prefer to call deliver directly. What do you think, is it a useful extension and does it work?

[Dovecot] v1.1.beta1 POP3 delete problem
by arvids 30 Sep '07

30 Sep '07

Hello, POP3 server does not delete mails when user quits POP3 session, but only at the next login. It looks so - user logs in with USER and PASS commands, at this moment new messages are moved from /new to /cur maildir folder. Then messages are deleted with DELE command(before deleting there can be other POP3 commands) and the user quits session. The server says "+OK Logging out, messages deleted.", but in fact messages are not deleted from the disk and stays in /cur folder. And these messages are deleted only when user logs in next time. dovecot -n: # 1.1.beta1: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

Hi, It seems that after I upgraded to 1.1beta1 it takes a few seconds first time I access a folder and i get this error : fcntl(/mail2/home/jon/.Maildir/.INBOX.Pren/dovecot.index.cache, F_RDLCK) failed: Bad file descriptor. No errors after that and it works fine. is this expected. Is it ok to continue using this? Best regards - Jon

[Dovecot] v1.0 vs 1.1b re: Postfix and Dovecot LDA
by Jerry Yeager 30 Sep '07

30 Sep '07

In running the various 1.0.n versions of Dovecot's LDA with the instructions in the wiki for using LDA with Postfix [on OS X 10.4] things went well using the instructions as-is (no setuid problems). This changed in moving over to the 1.1 beta. The LDA refused to work failing with the error "setgroups() failed: Operation not permitted" as I mentioned in a previous message. After reading the exchange between Bill Cole and Rich Winkel and following up on this, it seems that the new 1.1b wants you to give the Deliver app specific setuid permission via: cd /path/to/where/dovecot's/deliver/is sudo chmod u+s deliver Then things worked as before. There was no need to give the group 's' permission nor to change ownership of deliver from the default root:staff or root:wheel or whomever... . The error message seems odd though. I am not sure if, overall, this means there is a problem in Dovecot 1.0.n or that things are being tightened up in 1.1b. Thanks Bill and Rich for the tip! Jerry Yeager

Let's try to keep this on the list, shall we. Fábio M.

I don't see this as a problem at all (why create one when there's none to be found:): * Move message into Spam: it's a spam that should be reclassified. * Move message out of Spam: it's a ham that should be reclassified. Don't really care where the mail comes from or where it is moved. This is the beauty of it all, count the key or mouse clicks, can't be less than this:) * Using the expire plugin, the Spam folder will be emptied auto- matically in due time (typically 30 days maybe) without user intervention. All close to zero maintenance for sysadmin as well as end-user. > Well, by now I dont have much, but I really would like to know how to > find the filename of a message being copied from a folder to another. No such luck (I think): to my understanding (with the help of Johannes in previous reply in this thread), you'd have to create a temporary file with the mail message using tmpnam() + mail_get_stream() or similar, and then do your thing. I'm aiming towards that exact functionality: I want to be able to do training using "pristine" source (so I'll need the whole message), and keep the previous functionality using signatures. We'll see how it goes. Good Luck and thanks for your input /Lars
