[Dovecot] quota: maildrop + dovecot. dovecot doesn't update maildirsize file
by Frittella Laurento 26 Jul '07

26 Jul '07

Hi all, I'm trying to implement quota support in postfix using maildrop + dovecot but I think dovecot doesn't update info stored in maildirsize file. # 1.0.2: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ listen: 127.0.0.1 ssl_listen: * ssl_ca_file: ... ssl_cert_file: ... ssl_key_file: ... ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login valid_chroot_dirs: /home/vmail/domains first_valid_uid: 1001 last_valid_uid: 1001 first_valid_gid: 1001 last_valid_gid: 1001 mail_location: maildir:/home/vmail/domains/%d/%n auth default: user: dovecot-auth passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf plugin: quota: maildir:ignore=Trash When a mail arrives maildrop delivers it and update info in the maildirsize file, but when I delete messages through dovecot (using thunderbird) the maildirsize remains the same and so users reach overquota very soon. What's wrong? Thanks in advance, Laurento

[Dovecot] dspam plugin
by Oliver Kohll 26 Jul '07

26 Jul '07

Hello, I'm trying to install the dspam plugin to dovecot. So far, I've Installed dovecot 1.0.2 from RPM and set up Installed dspam 3.8.0, set up and integrated with postfix, using dspam as local delivery agent before dovecot's deliver Downloaded the dovecot 1.0.2 source in order to compile the C file http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration/ beta7-code with the command cc -fPIC -shared -Wall -I../src/ -I../src/lib -I.. -I../src/lib- storage -I../src/lib-mail -I../src/lib-imap -I../src/imap/ - DHAVE_CONFIG_H -DDSPAM=\"/usr/local/bin/dspam\" dspam.c -o lib_dspam.so and copied the resulting lib_dspam.so to /usr/lib/dovecot/imap/ In dovecot.conf, set protocol imap { mail_plugins = dspam mail_plugin_dir = /usr/lib/dovecot/imap } Created a SPAM folder. However, when I move a message into or out of the SPAM folder, dspam doesn't seem to execute. Nothing appears in /usr/local/var/dspam/system.log or /var/log/maillog and "SELECT * FROM dspam_stats;" in the dspam database returns unchanged numbers: dspam=> select * from dspam_stats ; uid | spam_learned | innocent_learned | spam_misclassified | innocent_misclassified | spam_corpusfed | innocent_corpusfed | spam_classified | innocent_classified -----+--------------+------------------+-------------------- +------------------------+----------------+-------------------- +-----------------+--------------------- 505 | 18 | 1870 | 3 | 3 | 0 | 3 | 0 | 0 (1 row) One thing that may be relevant is that I have a namespace in dovecot.conf namespace private { prefix = INBOX. inbox = yes } Any ideas?

[Dovecot] Vacation message functionality
by Charles Marcus 25 Jul '07

25 Jul '07

Hi, Since I will soon be attempting to get this working on one of my client's systems, I posed a question on the postfix list - since they mostly dislike vacation messages - but *ardent haters* of badly configured vacation message systems - as to the quality of the dovecot vacation message function. The only response I got did seem to have a few very good suggestions for additional conditions to test for, so I'm posting the response here to see if they can be incorporated (I'm not a coder or I'd attempt it myself). The original text (prefixed by double quote characters) in the following exchange is what I copied/pasted from the wiki, and the reply (prefixed by one quote character) is the suggested change/enhancement (this reply is from a trusted source on the postfix list): >> Vacation auto-reply >> >> The vacation replies are sent to the envelope sender. Currently this >> is taken from the Return-Path: header in the message. > comment: > or from the command line if this is supported. > > also, if the envelope sender is not available, no reply should be > sent. >> List of autoreplied senders is stored in .dovecot.lda-dupes file in >> user's home directory. When you're testing the vacation feature, it's >> easy to forget that the reply is sent only once in the number of >> configured days. If you've problems getting the vacation reply, try >> deleting this file. If that didn't help, make sure the problem isn't >> related to sending mails in general by trying the "reject" Sieve >> command. > if you support extensions, you can test using a unique sender each > time: foo+12345(a)domain.example. >> The automatic replies aren't sent if any of the following is true: >> >> <snip> >> >> o begins with "owner-" (case-sensitive) > replace with: > o starts with "${token}-" (not case sensitive), where token > is one of: owner, request, bounces > > It is safer to send nothing than send a risky one. >> o contains the string "-request" anywhere within it >> (case-sensitive) > replace with: > o contains "-${token}@" (not case sensitive), where token is > one of: owner, request, bounces >> * The envelope sender and envelope recipient are the same >> * The envelope recipient is not found in the message To:, Cc: or >> Bcc: fields. > add: > * There is a "Sender:" header containing one of the tokens listed > above. > * There is a List-Id or List-Post header > * There is no header suggesting that this is possible spam > > Unlike delivery, safety here is to not send a reply if the message > may be spam. so you don't rely on recipient preferences, and you > don't fear false positives too much (the guy who receives your > auto-rep may have a better filter, and besides annoying him, would > find you stupid to miss an obvious spam ;-p) >> The envelope sender is taken from a Return-Path: header in the >> message.

Comments appreciated... -- Best regards, Charles

[Dovecot] Thunderbird body search and multiple imap process
by Oliver Schulze L. 25 Jul '07

25 Jul '07

Hi, I'm having an issue with dovecot and Thunderbird and it is reproducible all the time. You do many body search from TB and you end up with multiple imap processess consuming all the CPU and with linux load 20+ Setup: - Centos 4.5 - Thunderbird 2.0.0.5 - Dovecot 1.0-7_53.rc29 and 1.0.1-1_58.el4 How to reproduce: - have an imap account in Thunderbird with 12000+ emails - user maildir in dovecot - do a: ps auwx|grep user1|grep imap|wc -l - in the main window of TB, in the sarch box select "Entire Message" - search one random word and wait 30 seconds - search another random word and wait 30 seconds - search another random word and wait 30 seconds - search another random word and wait 30 seconds - do another: ps auwx|grep user1|grep imap|wc -l - watch that the user1 have now more imap process - watch the linux load, it just rocketed from 1 to 20 - killall -9 imap - watch the linux load return to 1 I'm thinking its TB fault, anyone has seen this issue too? Thanks Oliver -- Oliver Schulze L. | http://tinymailto.com/oliver Asuncion - Paraguay | http://www.solojuegos.mobi

I'm just curious to know > what your motivation is. Why is it evil? Why do you hate it? EXPUNGE command is specified to expunge the mails, not move them to another mailbox. This would make having the message really gone a 4 stage operation: Mark deleted, expunge, mark deleted in Trash, expunge Trash. In many clients when you mark a message deleted it also copies it to Trash. So a server side expunge-to-trash feature causes the message to get copied there twice. A Trash mailbox also has the problem that all of your messages get there. There's no way to have an easy "unexpunge" operation, because the original mailbox isn't saved anywhere. You have to manually copy the message to the wanted mailbox. Perhaps lazy-expunge is a bit similar, but it preserves the mailboxes and doesn't conflict with clients' move-to-Trash feature. Also the concept in general is about having easily restorable backups of mails and not some kind of a idea that mails should go to a Trash mailbox when they're deleted. Maybe that whole Trash concept is the reason I consider it evil. I don't like that Trash concept in desktop environments either. I wish the undelete feature was in filesystems, so that when disk is full, the oldest deleted files would automatically get overwritten with new data, but until then the files would be undeletable. >> I think having a virtual Trash mailbox that contained all messages >> marked >> as deleted in all mailboxes would be a good solution for this. > > That's not quite the same thing.

[Dovecot] Quota plugin, Maildir, dict backend loop problem
by David Jonas 25 Jul '07

25 Jul '07

Hello, I've been working with the quota plugin(s) the past few days and have been having some real trouble. Only a few entries are appearing in the database, a couple more when I restarted dovecot. None of the current entries were being updated either. I think I've tracked it down to somewhere in the dict backend. I put in a few i_info() statements and recompiled. A few queries get through, then it seems to try the same query about three times and then no new more queries at all (the i_info is right after the allocation of the query string). I couldn't find any errors in the log. An strace of the dict pid shows the following loop. Dovecot -n to follow as well. A quick tcpdump showed a loop something like this: < SELECT current FROM quota WHERE ... > 513965019 < BEGIN < INSERT INTO quota (current, ... < COMMIT > ?? (error_r appears to be (null)) .. repeat .. In all my tests it appears that the quota value being set during the loop is 0, but that would be the most common case anyway. An insert query would look like this: INSERT INTO quota (current, path, username) VALUES (0, 'quota/storage', 'user(a)example.com') ON DUPLICATE KEY UPDATE current = current + 0; Help on what to do/try next would greatly be appreciated.

I get the following in mail.err: IMAP(doudou): file ostream-crlf.c: line 339 (_send_istream): assertion failed: ((size_t)ret <= iov.iov_len) IMAP(doudou): Raw backtrace: imap [0x10080384] -> imap(i_info+0) [0x10080120] -> imap [0x1008f70c] -> imap(o_stream_send_istream+0x7c) [0x1008d57c] -> imap(maildir_save_continue+0x4c) [0x1002bacc] -> imap(mailbox_save_continue+0x20) [0x1006d910] -> imap [0x1000f4b4] -> imap [0x1000fe44] -> imap(io_loop_handler_run+0x1b8) [0x10087ea8] -> imap(io_loop_run+0x38) [0x10086cf8] -> imap(main+0x474) [0x1001f714] -> /lib/tls/libc.so.6 [0xfe84994] -> /lib/tls/libc.so.6(__libc_start_main+0xb0) [0xfe84ad0] child 18757 (imap) killed with signal 6 The attached dovecot.txt contains the end of the tcp dump (dovecot aborts just after) System information: [~] dovecot --version 1.0.0 [~] dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_process_per_connection: no login_process_size: 16 login_processes_count: 1 login_max_connections: 3 max_mail_processes: 3 mail_extra_groups: mail mail_location: maildir:~/mail namespace: type: private separator: / inbox: yes auth default: mechanisms: plain login process_size: 16 passdb: driver: pam userdb: driver: passwd OS: linux debian etch, got dovecot 1.0.0-1~bpo.1 from www.backports.org CPU arch: powerpc Filesystem: ext3 -- Sylvain Joyeux

[Dovecot] qpopper -> dovecot migration : which pop3_uidl_format?
by bob passendon 25 Jul '07

Hello, I have read in lots of places about how I should use pop3_reuse_xuidl = yes to prevent pop3 users having to re-download mail (and duplicate their e-mail) after a migration. This fails with the message: pop3_uidl_format setting is missing from config file Which setting for pop3_uidl_format should I set to prevent the e-mail being downloaded again?
