Hi there, are there more trash plugin related updates since v1.1.4 ? I'm trying to use the plugin with dovecot+mysql according to documentation and get frequent segfaults Dec 4 13:58:21 mail kernel: [1605631.688946] imap[16662]: segfault at 95 ip b7f51a1e sp bfd36190 error 4 in lib20_expire_plugin.so[b7f50000+2000] Dec 4 13:58:22 mail kernel: [1605632.366633] imap[16765]: segfault at 14 ip b7edda21 sp bfdc1a10 error 4 in lib20_expire_plugin.so[b7edc000+2000] Dec 4 13:58:23 mail kernel: [1605633.063495] imap[16767]: segfault at 14 ip b7fd4a21 sp bfebab10 error 4 in lib20_expire_plugin.so[b7fd3000+2000] Dec 4 13:58:40 mail kernel: [1605650.013144] imap[16772]: segfault at 355 ip b7e41a1e sp bff27b80 error 4 in lib20_expire_plugin.so[b7e40000+2000] Dec 4 14:14:09 mail kernel: [1606578.801269] imap[15665]: segfault at 48d ip b7f3ca1e sp bfc22840 error 4 in lib20_expire_plugin.so[b7f3b000+2000] In changelog I see that there are updates for trash plugin going from v1.1.3 to v.1.1.4 Using v1.1.4 pre-build for Ubuntu server and lazy enough to do manual compilation... thanks for your time, Ivars

I'm using maildrop to filter mail like: xfilter "/usr/bin/spamc" xfilter "/usr/bin/bogofilter -ep" I want to change to deliver (so I can use sieve) but can deliver do this?

[Dovecot] confused about deliver
by Neal Becker 14 Dec '08

14 Dec '08

I have dovecot serving a maildir in ~/Mail.imap. In Mail.imap I have cur/ new/ tmp/ .maillist1/ .maillist1/cur .maillist1/new .maillist1/tmp ... I made a sieve script, which looks like: require "fileinto"; if header :is "Subject" "test" { fileinto "test"; } ... with no final else clase. When mail is delivered to a maillist, caught by my sieve script, it goes into the correct subdir of maildir. But, when not caught by the script, I get: Dec 14 11:53:27 localhost deliver(nbecker): msgid=<d9f848520812140850q190f104fva5f586e43fa03994(a)mail.gmail.com>: saved mail to INBOX I can't find this mail saved to INBOX. There are no modified directories under maildir that I can find. Where did this mail go? I wanted it to go into the toplevel cur/, which is where my client finds them.

[Dovecot] SIEVE resources ?
by Xavier Maillard 14 Dec '08

14 Dec '08

Hi, Do you any good SIEVE resources for a poor beginnner ? I'd to translate some of my current procmail rules into SIEVE. I have, for example, a "generic" rule that is able to sort almost any message from/to a mailing-list into a dedicated folder -i.e one rule for almost all my lists. Any recomendation ? Thank you

[Dovecot] Mailbox name
by Xavier Maillard 14 Dec '08

14 Dec '08

Hi, I am using SIEVE to filter/sort my incoming mails. I am subscribed to tens of mailing lists and I would like to file messages into folder of this pattern: INBOX/list/<tld>/<domain name>/<list name> So for example help-gnu-emacs(a)gnu.org would be filed under: INBOX/list/org/gnu/help-gnu-emacs The problem is Dovecot is telling me that this mailbox name is invalid. What can I do ? Cheers

[Dovecot] Imap logging and inetd
by Jonathan Siegle 14 Dec '08

14 Dec '08

When I ran /usr/local/sbin/dovecot, the variable login_log_format_elements from dovecot.conf was honored. Now when I run /usr/local/libexec/dovecot/imap-login from /etc/inetd.conf, it isn't. How do I get imap-login to write log lines that use login_log_format_elements for the format? This is dovecot-1.2.alpha3 soon to be alpha4. Thanks, Jonathan

[Dovecot] Panic in 1.1.6 file ioloop.c: line 206
by Laurent Blume 14 Dec '08

14 Dec '08

Hi all, I just had a panic with dovecot 1.1.6, two days after replacing 1.0.15 with it in production. Here are the logs immediately preceding the panic, I think they're related. It seems the user connected simultaneously from two different clients, from his own computer and a webmail running on the server, then manipulated mail folders on one side, and logged out. The panic occurred 3 seconds after the logout. Is there a setting I might have missed that could avoid that?

[Dovecot] proxy and master user
by Matthieu Herrb 14 Dec '08

14 Dec '08

Hi For some application we need a master user on our IMAP servers. We use dovecot 1.1.7 in proxy mode, with proxy_maybe (some mailboxes are on the proxy itself, others are on remote servers, also running dovecot). But the proxy removes the '*master' suffix from the username when using the master user to log in on the proxy. So the base name of the user with the master password are submitted to the real server, which of course fails. Is there a way to tell the proxy to forward the master user to the real server, without forcing it in destuser, since we also need to have regular (non master) logins? Thanks in advance. -- Matthieu Herrb

[Dovecot] Broken sorting(?)
by Michael M. Slusarz 14 Dec '08

14 Dec '08

Somewhere between revision f5554ae61732 (12 days ago) and the release of 1.2a4 (f53952ac4285; 9 days ago) sorting appears to have broken. With the older revision, I see the following (using Maildir): a sort (ARRIVAL) US-ASCII ALL * SORT 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 2 1 With the newest code, I see this: a sort (ARRIVAL) US-ASCII ALL * SORT 124 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 2 1 Obviously, that duplicate sequence number (124) is not a good thing (shouldn't the sequence numbers be in order for an arrival search anyway?). Deleting any message in the mailbox always makes the last sequence number appear at the beginning. I can verify that another IMAP server on the same machine views the mailbox just fine: a sort (arrival) US-ASCII ALL * SORT 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 michael

[Dovecot] Possible bug in Maildir++ quota?
by Ulrich Zehl 13 Dec '08

13 Dec '08

While researching a possible bug in our custom-made Maildir++ expiration script, I found the following in src/plugins/quota/quota-maildir.c. | static const char * | maildir_list_next(struct maildir_list_context *ctx, time_t *mtime_r) | { | [...] | *mtime_r = st.st_size; | return str_c(ctx->path); | } As far as I unterstand, this seems incorrect, because the value in mtime_r is used, for example, in maildirs_check_have_changed to check whether any maildirs or folders have changed. If this isn't a bug, please satisfy my own curiosity and tell me what I'm missing. Ulrich

After a couple of seconds when I try to start dovceot, I get this: root@taleira:~# /etc/init.d/dovecot start Alarm clock If I uncomment the "imap_quota and quota" in dovecot.conf everything seem to work fine: protocol imap { listen = *:143 ssl_listen = *:993 # problem pa taleira01: konstigt... #mail_plugins = quota imap_quota mail_plugins = } I can't really figure out what's wrong. There's nothing in the log and dovecots error message is not so talkative. It took a while to figure out that it was the quota that caused the problem. I guess there is something with the underlying FS, but all kernel modules are loaded as far as I know. The maildir is on a nfs-mounted disk. The whole system is on a XEN machine and I have multipe copies of this image running on other machines with no problem. Strace gives me: root@taleira:~# strace dovecot .... lstat64("/var/run/dovecot//login", {st_mode=S_IFDIR|0750, st_size=60, ...}) = 0 open("/var/run/dovecot//login", O_RDONLY|O_NONBLOCK|O_LARGEFILE| O_DIRECTORY|0x80000) = 4 fstat64(4, {st_mode=S_IFDIR|0750, st_size=60, ...}) = 0 getdents64(4, /* 3 entries */, 4096) = 88 lstat64("/var/run/dovecot//login/ssl-parameters.dat", {st_mode=S_IFREG| 0644, st_size=230, ...}) = 0 getdents64(4, /* 0 entries */, 4096) = 0 close(4) = 0 geteuid32() = 0 pipe([4, 5]) = 0 fcntl64(4, F_GETFD) = 0 fcntl64(4, F_SETFD, FD_CLOEXEC) = 0 fcntl64(5, F_GETFD) = 0 fcntl64(5, F_SETFD, FD_CLOEXEC) = 0 dup(2) = 6 fcntl64(6, F_GETFD) = 0 fcntl64(6, F_SETFD, FD_CLOEXEC) = 0 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID| SIGCHLD, child_tidptr=0xf7e666f8) = 3343 close(6) = 0 close(5) = 0 alarm(5) = 0 wait4(-1, 0xffbd7e9c, 0, NULL) = ?

[Dovecot] freebsd 7, panics - kqueue?
by mike-maillist＠nux.co.uk 12 Dec '08

12 Dec '08

Hi, We have a issue with a server pretty much just running dovecot, there's about 250gb of maildirs which has about 200 simultaneous connections to it running on freebsd 7. The machine has stayed up for about 8 days before it panics but sometimes panics after about 24 hours. We are running a PAE kernel (with ULE scheduler) as the machine has 2 (4 core processors) and 8gb of ram, dovecot is compiled with kqueue support which i suspect is causing the panics. We are currently trying with a GENERIC kernel to see if this addresses the issue but looking back through the dovecot lists there seems to be some issue with kqueue, freebsd and dovecot, i am tempted to simply disable kqueue in dovecot but am not sure on the performance penalties. Please see the freebsd pr for the kgdb dumps - for both dumps the current process was imap, and the second one seemed to hint towards a problem with kqueue but im not a c or kernel hacker: http://www.freebsd.org/cgi/query-pr.cgi?pr=129550 --- snip of what i think is relevent from the dump --- (kgdb) list *0xc04c4c4d 0xc04c4c4d is in knlist_remove_kq (/usr/src/sys/kern/kern_event.c:1615). 1610 if (!kqislocked) 1611 KASSERT((kn->kn_status & (KN_INFLUX|KN_DETACHED)) == KN_INFLUX, 1612 ("knlist_remove called w/o knote being KN_INFLUX or already removed")); 1613 if (!knlislocked) 1614 knl->kl_lock(knl->kl_lockarg); 1615 SLIST_REMOVE(&knl->kl_list, kn, knote, kn_selnext); 1616 kn->kn_knlist = NULL; 1617 if (!knlislocked) 1618 knl->kl_unlock(knl->kl_lockarg); 1619 if (!kqislocked) (kgdb) mail# dovecot -n # 1.1.7: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.0-RELEASE-p6 i386 ssl_cert_file: /etc/ssl/dovecot.pem ssl_key_file: /etc/ssl/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_process_per_connection: no login_processes_count: 20 login_max_processes_count: 256 login_max_connections: 512 max_mail_processes: 1024 verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 mail_privileged_group: mail imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: passdb: driver: vpopmail userdb: driver: vpopmail

[Dovecot] Dovecot authentication not supported in Entourage
by jan gestre 12 Dec '08

12 Dec '08

Hi Guys, I recently configured an mail server running postfix + dovecot + mysql + postfixadmin, everything is running ok except for Mac Entourage clients which is a PITA IMO, I always get a authentication not supported error while thunderbird and outlook on windows don't. Any ideas or workaround? my dovecot version is dovecot-1.0.7-2.el5. here's the output of dovecot.conf and dovecot-sql.conf respectively: # dovecot -n # 1.0.7: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/postfix/ssl/mail-cert.pem ssl_key_file: /etc/postfix/ssl/mail-key.pem login_dir: /var/run/dovecot//login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_access_groups: mail mail_location: maildir:/home/virtualmail/%d/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 user: nobody passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 432 user: virtualmail group: mail # cat /etc/dovecot-sql.conf [root@mail ~]# cat /etc/dovecot-sql.conf driver = mysql connect = host=localhost dbname=postfix user=dovecot password=dovecot69 default_pass_scheme = MD5 user_query = SELECT '/home/virtualmail/%d/%n' as home, 'maildir:/home/virtualmail/%d/%n' as mail, 150 AS uid, 12 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' # Get the password password_query = SELECT username as user, password, '/home/virtualmail/%d/%n' as userdb_home, 'maildir:/home/virtualmail/%d/%n' as userdb_mail, 150 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' TIA.

[Dovecot] Duplicate suppression from remote lists?
by Adam Seering 12 Dec '08

12 Dec '08

Hi, I have a setup where users on my server who are subscribed to several lists on a (remote) weirdly-configured listserver are getting many duplicate e-mails. I know why this is happening; but I don't have control over that listserver so I can't fix it. Is there a way for me to suppress duplicates from within Dovecot? The duplicates do all have the same (otherwise-unique) message ID. "dovecot --version" gives 1.0.rc15. I'm using exim for SMTP. I'm also using dovecot-lda, with the Sieve plugin. There's a rather old thread on this list that mentions that dovecot-lda+Sieve should be able to suppress duplicates; it's not doing so automagically, though... Thanks, Adam

[Dovecot] W= fixup feature
by Arkadiusz Miskiewicz 12 Dec '08

12 Dec '08

Hi, When there are maildir mail files without W= tag in name then dovecot opens them, read data inside to calculate W= size, cache that information etc. Would be it sensible to have option where dovecot would fix names of such files? Like if no W= then after calculating size rename file to actually contain W= ? -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/
