[Dovecot] Missing TMP folder - Dovecot 1.2 Beta3
by Matt Rude 26 Mar '09

26 Mar '09

Recently after upgrading to 1.2 Beta3 from 1.1.13, I started to defer mail. After looking into it deeper, it looks like Dovecot/sieve now asks for a tmp folder in the imap (maildir) folder. Once I added the tmp folder as the logs indicants, the mail was processed normally. I have split my Inbox and imap store to different folder. Looking at what it's trying to do, it looks to me that dovecot/sieve expect the imap directory to be the Inbox. Is this a bug, or intended behaver? # Log output, when requeueing the message in postfix, with mail_debug on ######################################################################### Mar 24 12:02:50 samantha postfix/qmgr[6855]: EB4141237BD: from=<colleen(a)example.com>, size=493284, nrcpt=1 (queue active) Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Loading modules from directory: /usr/local/lib/dovecot/lda Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib20_expire_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: maildir=example.com/jill@example.com/ Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: uid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: gid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: quota_rule=*:storage=524288 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota root: name=User quota backend=maildir args= Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=* bytes=536870912 messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Trash bytes=53687091 (10%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Junk bytes=107374182 (20%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir: data=/var/spool/virtualmailboxes/example.com/jill@example.com/imap/:INBOX=/… Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir++: root=/var/spool/virtualmailboxes/example.com/jill@example.com/imap, index=/var/spool/virtualmailboxes/Indexes/example.com/jill@example.com, control=, inbox=/var/spool/virtualmailboxes/example.com/jill@example.com Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: /var/spool/virtualmailboxes/example.com/jill(a)example.com/dovecot.sieve doesn't exist Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Using sieve path: /var/spool/sieve/dovecot.sieve Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Executing script /var/spool/sieve/dovecot.sievec Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Namespace : Using permissions from /var/spool/virtualmailboxes/example.com/jill(a)example.com/imap: mode=0700 gid=-1 ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): creat(/var/spool/virtualmailboxes/example.com/jill@example.com/imap/tmp/tem… failed: No such file or directory ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): copy: i_stream_read() failed: No such file or directory Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): msgid=<85866319ca18bf9cd994e34fe806c4f5.squirrel(a)mail.mattrude.com>: save failed to INBOX: Internal error occurred.

I use dovecot mailbox as destination of fetches from a few POP mailboxes. I would like to pass name of "source mailbox" to sieve script via deliver's command line option(s). As I understand I should use -a "mailbox@domain". How it would be accessible in sieve script? -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu It is always the best policy to tell the truth, unless, of course, you are an exceptionally good liar. -- Jerome K.

[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?

[Dovecot] selection correct auth with multiple auth methods
by jm 25 Mar '09

25 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.
