[Dovecot] Segfault with soft disk quota
by Tim Boyer 01 Apr '08

01 Apr '08

RHEL 5.1, dovecot 1.0.rc15 on a x86 system. dovecot -n says [root@dg mail]# dovecot -n # /etc/dovecot.conf protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login login_process_size: 64 first_valid_uid: 100 mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd I had one user whose Outlook kept giving disconnection problems. I looked at the logs, and found this: Mar 31 14:05:31 dg.denmantire.com dovecot: POP3(bfarner): open(/home/bfarner/Mail/.imap/INBOX/.temp.dg.denmantire.com.4668.564b08eac94 4fe4a) failed: Disk quota exceeded Mar 31 14:05:31 dg.denmantire.com dovecot: POP3(bfarner): Fixed index file /home/bfarner/Mail/.imap/INBOX/dovecot.index: log file sync pos 2,115528 -> 3, 24 Mar 31 14:05:31 dg.denmantire.com dovecot: POP3(bfarner): Fixed index file /home/bfarner/Mail/.imap/INBOX/dovecot.index: messages_count 3 -> 0 Mar 31 14:05:31 dg.denmantire.com dovecot: pop3-login: Login: user=<bfarner>, method=PLAIN, rip=192.168.0.37, lip=192.168.0.2 Mar 31 14:05:31 dg.denmantire.com pop3[4668]: segfault at 0000000000000000 rip 00000000004452e8 rsp 00007fff56ccd460 error 4 Mar 31 14:05:31 dg.denmantire.com dovecot: child 4668 (pop3) killed with signal 11 Strange thing is - he's over disk quota, but just over the soft quota - nowhere close to the hard quota. Easy for me to fix, but I figured I'd also submit it as a bug. I don't follow the list so if you need any more info, please copy my email on the reply.

[Dovecot] Bug in db-ldap.c with Dovecot1.1rc3
by richs＠whidbey.net 01 Apr '08

01 Apr '08

If using LDAP as a userdb with a "quota_rule" configured, the order of the LDAP entry can distort userdb results, depending on where the quota attribute is found. For instance, with this "dovecot-ldap.conf" snippet: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaKb=quota_rule=*:storage=%$ And this example LDAP entry: dn: uid=testuser,ou=people,dc=domain.com uid: testuser homeDirectory: /mail/testuser gidNumber: 100 cn: testuser quotaKb: 20480 uidNumber: 121212 When db_ldap_result_iterate_next_all() runs, "quotaKb" is encountered, which causes "ctx->template" to be set. On the next iteration, "uidNumber" is encountered, but "ctx->template" is still set, causing the "uid" value to be prepended with "*:storage=". This is reflected by an error in the log as: Invalid UID value '*:storage=121212' This can be fixed by adding a line after 1118 to src/auth/db-ldap.c: ctx->template = NULL; Hope this is helpful to someone, -Rich

[Dovecot] Wrong UIDs returned from mailbox_transaction_commit_get_uids()
by Ron Avriel 01 Apr '08

01 Apr '08

Hi, Wrong UIDs are returned from mailbox_transaction_commit_get_uids() in dovecot-1.1.rc3. The problem is in: int mailbox_transaction_commit(struct mailbox_transaction_context **t) { uint32_t tmp; return mailbox_transaction_commit_get_uids(t, &tmp, &tmp, &tmp); } It should be: int mailbox_transaction_commit(struct mailbox_transaction_context **t) { uint32_t tmp1, tmp2, tmp3; return mailbox_transaction_commit_get_uids(t, &tmp1, &tmp2, &tmp3); } After this fix it works OK.

[Dovecot] public folders fchown error
by junk＠mc1.mccarthy.ac 01 Apr '08

01 Apr '08

I was hoping this would be the right place to look for some help, I cannot make public folders get the right permissions. I continually get the fchown error in logs, and have googled high an low to find multiple solutions that do not work for me. I'm using maildir. I have sendmail with postfix distributing my mail. I created maildir's in each users personal directory. I then thought it would be neat to set up a public folder that people could dump spam and ham into, then have a cron script go through the directory and automatically sort it for bayes. However, when I put a file in the public folder, the permissions do not seem to work. I've put a dovecot-shared file with root.mail permissions, 660, in just about every directory (all the public folder directories, and every personal user's control and index location), I've chmod'd to 777 each file and folder to test, etc, and no matter what, the dovecot.index.tmp in the user's index folder comes through with their permissions, and this error shows up. Am I thinking this is something different then what it is or am I completely off base? Thanks in advance, Bob dovecot 1.0.13 (debian install) # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/%u/Mail/Inbox umask: 7 mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: public separator: / prefix: Public/ location: maildir:/var/mail/public:CONTROL=~/Mail/public/public:INDEX=~/Mail/public/index namespace: type: private separator: / inbox: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd

[Dovecot] Setting for deleting old messages from Trash?
by David Rosenstrauch 31 Mar '08

31 Mar '08

Hi. Just switched to Dovecot from Courier last week and have been very pleased so far. The conversion was extremely painless, and I only hit a few small configuration issues before I was able to get the server up and running. Since then, I've been quite pleased - Dovecot's been very stable, and a good bit faster than courier as well. However, there's one nice feature from courier that I used to use that it doesn't seem like Dovecot provides. Wanted to see if that was indeed the case and, if so, if there was any workaround. In Courier, there was a setting whereby the server would automatically delete messages in the Trash once they were of a certain age. (The default was 7 days.) However, looking through the dovecot.conf, it didn't appear that Dovecot had any comparable setting. Anyone know how I might achieve this with Dovecot? TIA, DR

[Dovecot] mbox with sub-folders and messages?
by Richard Lefebvre 31 Mar '08

31 Mar '08

Hi, Is it possible to have dovecot configured to use mbox format and yet have folders that contains sub-folders and messages? I'm thinking of a simple setup where any files directory with extension .sbd are presented to the IMAP client without the extension. So if you have a mbox file named BOX01 and a directory name BOX01.sdb would show has one on the client side (note: that is the way Thunderbird keeps it's mail locally). I know that the Maildir format does the sub-folders+messages, but I'm not really interested by the one file per email. Richard

Re: [Dovecot] outlook2007 shows frequent imap disconnect no matterwhat, outlook-idle setting in dovecot.conf

Hello all, I configured imap_client_workarounds = outlook-idle after a customers complaint (Windows Vista, Outlook 2007) and after a week, she reports me that the issue has never repeated.

[Dovecot] Flags can be changed in read-only mode
by Ron Avriel 30 Mar '08

30 Mar '08

Hi, It seems that IMAP flags can be changed in EXAMINE read-only mode. Luckily, messages cannot be expunged. This happens in both dovecot 1.0.12 and 1.1.rc3: * OK Dovecot ready. 1 login *** *** 1 OK Logged in. 2 examine inbox * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 1 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1206865015] UIDs valid * OK [UIDNEXT 2] Predicted next UID 2 OK [READ-ONLY] Select completed. 3 fetch 1:* flags * 1 FETCH (FLAGS (\Recent)) 3 OK Fetch completed. 4 store 1:* +flags (\Deleted) * 1 FETCH (FLAGS (\Deleted \Recent)) 4 OK Store completed. 5 fetch 1:* flags * 1 FETCH (FLAGS (\Deleted \Recent)) 5 OK Fetch completed. 6 expunge 6 OK Expunge completed. 7 fetch 1:* flags * 1 FETCH (FLAGS (\Deleted \Recent)) 7 OK Fetch completed.

[Dovecot] Proxy Problems
by Richard Cooper 28 Mar '08

28 Mar '08

Hi, I'm trying to use dovecot as a proxy as described on http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy but without much success. The problem is that when I send a IMAP login command dovecot is responding with "BYE Internal login failure. Refer to server log for more information." Can anyone help me shed light on this problem?

[Dovecot] Using LDA with postfix and virtual users
by Chris Cohen 28 Mar '08

28 Mar '08

Hi list, I have 7 virtual users in a sql database. I don't want any systemusers or local delivery using postfix. On the postfix side everything works fine as long as I use the 'local' delivery agent. But since I want to use dovecot's sieve functionality I set local_transport to dovecot. From now on Postfix seems to ignore local_* settings like local_recipient_maps. Here is my current configuration: log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps managesieve login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:/var/mail/%u mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): /var/mail/%u/dovecot/sieve/ sieve(default): sieve(imap): sieve(managesieve): /var/mail/%u/.dovecot.sieve auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/var/mail/%u socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: sieve: /var/mail/%u/.dovecot.sieve And my postfix configuration: alias_maps = mysql:/etc/postfix/alias_maps-mysql.cf command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/lib/postfix data_directory = /var/lib/postfix inet_interfaces = all local_recipient_maps = mysql:/etc/postfix/local_recipients-mysql.cf $alias_maps local_transport = dovecot mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = unixhosts.org myhostname = amy.unixhosts.org mynetworks = 127.0.0.0/8 myorigin = $myhostname smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) unknown_local_recipient_reject_code = 550 And accourding to the wiki I have: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user} As soon as I set local_transport to dovecot postfix seems to lookup local_recipients using dovecot.
