sqlite 3.6.11 doesn´t update from portmanager -u -l, conflicts with apache 2.2.11_3 and dovecot-1.1.11 on FreeBSD 7.1 I unselect into make config window the option to apache and dovecot and make deinstall reinstall, until sqlite fixed the dependence. am I OK?

[Dovecot] Dbox Upgrade Problem With MAILBOXDIR
by Alan Swanson 25 Mar '09

25 Mar '09

Hi. Trying to upgrade from Dovecot 1.1.11 to 1.1.13 but having a problem with imap process segfaulting. Backtrace is below. I presume it's related to these MAILBOXDIR changes but the only documentation is the single line in the news for changing to ":MAILBOXDIR=mailboxes" when using dbox. Current configuration is "mail_location = dbox:~/Mail" so what exactly should be changed here? (gdb) bt full #0 0x08093546 in dbox_get_list_settings (list_set=0xafe33244, data=0xafe34e33 "/home/USER/Mail", flags=MAIL_STORAGE_FLAG_NO_AUTODETECTION, layout_r=0xafe331e0, alt_dir_r=0xafe331dc, error_r=0xafe33304) at dbox-storage.c:76 subs_fname = 0x810fd7c "subscriptions" debug = false #1 0x08093615 in dbox_create (_storage=0x9405d08, data=0xafe34e33 "/home/USER/Mail", error_r=0xafe33304) at dbox-storage.c:103 storage = (struct dbox_storage *) 0x9405d08 list_set = {root_dir = 0x93fc038 "/home/USER/Mail", index_dir = 0x0, control_dir = 0x0, inbox_path = 0x0, subscription_fname = 0x810fd7c "subscriptions", maildir_name = 0x810fd8d "dbox-Mails", mailbox_dir_name = 0x0, mail_storage_flags = 0x0, lock_method = 0x0} st = {st_dev = 12674028786447048160, __pad1 = 61096, __st_ino = 155213040, st_mode = 135297936, st_nlink = 2950902296, st_uid = 135192819, st_gid = 155213040, st_rdev = 0, __pad2 = 20, st_size = -6340927589388910560, st_blksize = -1344064952, st_blocks = 666635824201130632, st_atim = {tv_sec = 20, tv_nsec = -1344064952}, st_mtim = {tv_sec = 135387904, tv_nsec = 1}, st_ctim = {tv_sec = 1, tv_nsec = 155213040}, st_ino = 34514951600} layout = 0x810fd8a "fs" alt_dir = 0x0 #2 0x080b1f12 in mail_storage_create (ns=0x9405900, driver=0x93fc030 "dbox", data=0xafe34e33 "/home/USER/Mail", user=0xafe34830 "USER", flags=MAIL_STORAGE_FLAG_NO_AUTODETECTION, lock_method=FILE_LOCK_METHOD_FCNTL, error_r=0xafe33304) at mail-storage.c:224 storage_class = (struct mail_storage *) 0x8128be0 storage = (struct mail_storage *) 0x9405d08 classes = (struct mail_storage * const *) 0xafe332a0 home = 0xa8007ff4 "|�\024" value = 0x2 <Address 0x2 out of bounds> i = 0 count = 1 #3 0x080b0815 in mail_namespaces_init (pool=0x94058e8, user=0xafe34830 "USER", namespaces_r=0xafe33360) at mail-namespace.c:230 namespaces = (struct mail_namespace *) 0x0 ns = (struct mail_namespace *) 0x9405900 ns_p = (struct mail_namespace **) 0xafe33310 flags = 0 lock_method = FILE_LOCK_METHOD_FCNTL mail = 0xafe34e2e "dbox:/home/USER/Mail" data = 0x0 error = 0x0 i = 1 #4 0x0806c373 in main_init () at main.c:238 client = (struct client *) 0x0 ns = (struct mail_namespace *) 0x49c953ed user = 0xafe34830 "USER" str = 0x0 #5 0x0806c59a in main (argc=1, argv=0xafe33434, envp=0xafe3343c) at main.c:296 No locals.

[Dovecot] selection correct auth with multiple auth methods
by jm 24 Mar '09

24 Mar '09

How do you control which socket or authentication process dovecot's pop3 daemon chooses to use? I've got a user database with two flags one to allow pop3 access and the other to allow the use of auth smtp. There are two authentication instances configed, thus, auth default { .... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = group = } } auth postfix { ..... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } From the logs and testing pop3 is using the postfix authentication instance and not the default as expected. Does anyone out there know how control dovecot's pops daemon authentication choice? This infomation seems to be lacking in the documentation I can find. Jeff.

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 24 Mar '09

24 Mar '09

Hi Timo, Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] Problem with dovecot + imap idle + qmail-local delivery
by Jochen Schug 24 Mar '09

24 Mar '09

Hi, I've recently switched from courier-imap to dovecot. Everything seemed to work fine, but after I while I noticed that dovecot is occasionaly causing problems with delivery of new incoming mails. System: Gentoo Linux, kernel 2.6.19, qmail 1.03, vpopmail 5.4.26 , dovecot 1.1.11, maildir, mail store on ext3. Symptoms: qmail is having trouble with the mail delivery. First I thought it had something to do with vpopmail or dovecot's quota support, but I tracked it down to qmail-local. I tried two different versions, one with Bill Shupp's maildir++ patch and one without. With the patch, I'm getting "User_over_quota._(#5.1.1)" errors. Mail is delivered once and sender is sent a notification about the exceeded quota. Without the patch, I get "Temporary_error_on_maildir_delivery._(#4.3.0)". Mail is delivered, but delivery is tried again and again. This only happens if a MUA is logged in to the mailbox and IMAP IDLE is being used. If the MUA is disconnected: fine. If dovecot is stopped: fine. I tried a couple of different things, all without success: - upgraded dovecot from 1.1.7 to 1.1.11 - compiled a new kernel with inotify support and recompiled dovecot - migrated mail store from reiserfs to ext3 - disabling quota support in dovecot - tried dovecot's various file locking mechanisms Right now I'm working around this by removing IDLE from the capabilities. This solves the problem, but leaves me with a less functional IMAP server. Any help is greatly appreciated.

[Dovecot] Staged migration from mbox to maildir
by Stewart Dean 24 Mar '09

24 Mar '09

So much changes in this migration that the ideal way to do it would be to begin with a few users or a department, then migrate the users affinity group by affinity group: first an institute or so, then the faculty, then the staff, then the students, moving to bigger and bigger groupings as the bugs work out of the migration and the move becomes more assured. We use sendmail and procmail. There's no problem there, as the ~./procmailrc can be changed to over-ride the mbox default until all groups are done and it become the default. The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine. Is this correct or am I (hopefully) wrong and there *is* a way to change things on the server that allows for staged migration? Oh, I would so like to be wrong!

[Dovecot] Released Sieve v0.1.4
by Stephan Bosch 23 Mar '09

23 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
