[Dovecot] unlink_directory(....Trash.NewFolder) failed: Directory not empty
by Adam McDougall 18 Nov '07

18 Nov '07

I noticed the following this week. No idea how long its been happening because I have not tested deleting folders hardly at all. Steps to reproduce: 1. Create a folder "NewFolder", click on it in thunderbird so an index dir is created: ls -ldi Maildir/.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.NewFolder/ total 0 4198833 -rw------- 1 mcdouga9 egrstaff 128 Nov 16 19:44 dovecot.index.log 2. Delete "NewFolder" which makes Thunderbird move both the folder under Trash, and seems to "rename" the .NewFolder index dir to .Trash.NewFolder (same inode #): ls -ldi Maildir/.Trash.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.Trash.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ total 4 4198833 -rw------- 1 mcdouga9 egrstaff 128 Nov 16 19:44 dovecot.index.log 3. Right click on Trash folder in Thunderbird, choose "Empty Trash": Nov 16 19:47:25 boomhauer dovecot: IMAP(mcdouga9): unlink_directory(/home/mcdouga9/Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder) failed: Directory not empty ls -ldi Maildir/.Trash.NewFolder/ 1504062 drwx------ 5 mcdouga9 egrstaff 4096 Nov 16 19:44 Maildir/.Trash.NewFolder/ ls -ldi Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ 4198832 drwx------ 2 mcdouga9 egrstaff 4096 Nov 16 19:47 Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ ls -li Maildir/dovecot/boomhauer/private/indexes/.Trash.NewFolder/ (sometimes has a .nfs.blahblah file, I think I failed to catch it quick enough this time) The folder dissapears from Thunderbird's view but stays on disk, and will reappear in Thunderbird if you collapse and re-expand the folder tree, or close and open thunderbird.

[Dovecot] umask not applied
by Thomas 18 Nov '07

18 Nov '07

Hi all! I am trying to get dovecot-1.0.rc15 to create files with mode 660 in my virtual mailboxes. I set umask=0007 in dovecot.conf, restarted dovecot (/etc/init.d/dovecot restart) and send me an e-mail but it is still 600. "dovecot -n" says "umask: 7" How come the zeros are not displayed? Is this by intention or is something wrong? Here is the complete output: # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%n umask: 7 auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail I searched the wiki and googled but couldn't find anything helpful.

[Dovecot] SIGSEGV (Segmentation fault) with antispam plugin
by Boky 18 Nov '07

18 Nov '07

Hi all. I am trying to get dovecot (1.0.rc17) running with antispam plugin. I have created another backend, which executes "sa-learn" from spamassassin's arsenal. The backend is modeled after sendmail backend. But I can't seem to get the plugin working wit either my backend or signature-log. This is my ".config": DOVECOT=/usr/src/dovecot-1.0.7 DOVECOT_VERSION=1.0 BACKEND=spamassassin-exec INSTALLDIR=/usr/lib/dovecot/modules/imap/ PLUGINNAME=antispam This is how I make the plugin: make && make install && chmod 644 /usr/lib/dovecot/modules/imap/lib90_antispam_plugin.so Since Ubuntu server does not come with dovecot sources, I have downloaded dovecot-1.0.7 and put it in /usr/src. As far as I understand, only the headers are needed, so this should not be the cause of the crash (if the headers hadn't changed). When invoked from dovecot process, the "imap" dies with signal 11. When running: strace /usr/sbin/dovecot --exec-mail imap This is how it ends: etdents64(8, /* 14 entries */, 4096) = 592 getdents64(8, /* 0 entries */, 4096) = 0 open("/usr/lib/dovecot/modules/imap/lib90_antispam_plugin.so", O_RDONLY) = 9 read(9, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\340\21"..., 512) = 512 fstat64(9, {st_mode=S_IFREG|0644, st_size=19252, ...}) = 0 mmap2(NULL, 16148, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 9, 0) = 0xb7f29000 mmap2(0xb7f2c000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 9, 0x2) = 0xb7f2c000 close(9) = 0 close(8) = 0 stat64("/var/mail/mailboxes/boky/Maildir/subscriptions", 0xbfc17d2c) = -1 EACCES (Permission denied) lstat64("/var/mail/mailboxes/boky/Maildir/cur", 0xbfc17c3c) = -1 EACCES (Permission denied) write(2, "imap(boky): ", 12imap(boky): ) = 12 write(2, "Error: ", 7Error: ) = 7 write(2, "lstat(/var/mail/mailboxes/boky/M"..., 69lstat(/var/mail/mailboxes/boky/Maildir/cur) failed: Permission denied) = 69 write(2, "\n", 1 ) = 1 open("/etc/localtime", O_RDONLY) = 8 fstat64(8, {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 fstat64(8, {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7de2000 read(8, "TZif\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\6\0\0\0\6\0"..., 4096) = 696 close(8) = 0 munmap(0xb7de2000, 4096) = 0 stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=696, ...}) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Process 4707 detached antispam plugin was downloaded from: http://git.sipsolutions.net/?p=dovecot-antispam.git;a=snapshot;h=HEAD;sf=tgz Please advise me n next steps; I'm just a beginner with debugging C/C++.

[Dovecot] crash with fts_squat on an identified email
by Adam McDougall 18 Nov '07

18 Nov '07

I have some folders with a good amount of spam. While demonstrating full text search to a user, we found a folder that would crash dovecot while doing a fts. While splitting up the mailbox to narrow it down, I found there are a good number of messages in that folder that all made it crash in the same manner. I figured I'd narrow down a single one, get that fixed, then retest the rest. I also added to my todo list to try a full text search on as much email as I can find, to try to weed out any other problems (and see if fts is realistic to use in production). Nov 17 09:03:26 boomhauer dovecot: IMAP(mcdouga9): file message-decoder.c: line 201 (translation_buf_decode): assertion failed: (*size >= skip) Nov 17 09:03:26 boomhauer dovecot: child 14668 (imap) killed with signal 6 Let me know if this is not reproducable with the attached tgz containing a maildir with one message, I could do a local gdb if needed.

[Dovecot] mailbox size limit
by Bazy 18 Nov '07

18 Nov '07

Hi guys, I was wondering... my Inbox is 1.3GB large, my mailbox size limit is 6GB (6442450941). Other users have 500+ MB in their Inbox. I have about 27GB of mail. I'm running dovecot 1.0.7 now under Fedora 7 with postfix. I have no trouble at all, everything is working perfect. I use ext3 as my file system, and I store mail in maildir format. Will I have any inode, file system, issues? Is anyone storing more then 27GB in maildir format on only one ext3 partition? Here is my dovecot -n output: # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 ssl_cert_file: /etc/postfix/smtpd.cert ssl_key_file: /etc/postfix/smtpd.key 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 login_max_processes_count: 512 mail_location: maildir:/home/vmail/%d/%n/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-userdb-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: quota: maildir:storage=102400 [root:pts/0][~]# cat /etc/dovecot-sql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock user=mail_admin password=XXXXXXXX dbname=mail default_pass_scheme = CRYPT password_query = SELECT password FROM users WHERE CONCAT(SUBSTRING_INDEX(email,'@',1)) = '%n' AND CONCAT(SUBSTRING_INDEX(email,'@',-1)) = '%d'; [root:pts/0][~]# cat /etc/dovecot-userdb-sql.conf driver = mysql connect = host=/var/lib/mysql/mysql.sock user=mail_admin password=XXXXXXXX dbname=mail user_query = SELECT CONCAT(('/home/vmail/'), SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/') as home, 5000 as uid, 5000 as gid, CONCAT('maildir:storage=', floor(quota/1024)) as quota FROM users WHERE email = '%u';

[Dovecot] Path to public folder subscription file not created in 1.1b7?
by Adam McDougall 17 Nov '07

17 Nov '07

I use CONTROL=%h/Maildir/dovecot/public/control/[namespace] for each of my public namespaces. A few nights ago, I noticed having a new user subscribe to public folders for the first time will silently fail, becuase the path up to the subscriptions file will not be created. I am pretty sure dovecot used to create it for me, but maybe that changed in a recent version, or maybe I did something to break it? Work around is to mkdir -p /home/[user]/Maildir/dovecot/public/control/[namespace] but I'd like to avoid having to do that. Once I create the directory and make sure it is writable, the client can subscribe to public folders in that namespace. If they do not have permission, it still silently fails. namespace: type: public separator: / prefix: #shared/decs/ location: maildir:/egr/mail/shared/decs:CONTROL=%h/Maildir/dovecot/public/control/decs:INDEX=%h/Maildir/dovecot/%q/public/indexes/decs list: yes subscriptions: yes

[Dovecot] Mail.app IDLE support
by Martin R. Ehmsen 16 Nov '07

16 Nov '07

Hi, I'm trying to use the new IDLE support in Mail.app on Mac OS 10.5, and it works sort of, but it seems to miss some notifications. My guess is the IDLE support in Mail.app is implemented such that it sets up a connection for IDLE notifications and then checks the mail via another connection, and because of that the "IDLE-connection" gets disconnected for inactivity after 30 min. The reason for my guess is that I get the following in my logs: dovecot: Nov 14 17:00:29 Info: imap-login: Login: user=<amanda>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:29 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:30 Info: imap-login: Login: user=<amanda>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:50 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:00:51 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:04:58 Info: imap-login: Login: user=<ehmsen>, method=PLAIN, rip=::ffff:xxx.xxx.xxx.xxx, lip=::ffff:192.168.1.2, TLS dovecot: Nov 14 17:30:40 Info: IMAP(amanda): Disconnected for inactivity dovecot: Nov 14 17:43:29 Info: IMAP(amanda): Disconnected for inactivity Is there something I can do about this problem? Is the IDLE implementation in the 1.1 branch different from the implementation in the 1.0 branch of dovecot? Or can I debug this issue further? I guess these things are standardized, but it seems hard for Apple to follow a standard :-) Thanks in advance, Martin R. Ehmsen
