[Dovecot] Dovecot crash non stop: "uid 0: exited on signal 11"
by Amaury Le Pivain 05 Dec '11

05 Dec '11

Hi all, I have an old physical freebsd 6.2 server running Dovecot 1.0.7. I wanted to virtualised it. So, I did a dd from the physical server and then I restored it on then now Virtual Machine. I booted the server, all services are running just fine excepted Dovecot. I tried to investigate the log as much as I can but i'm not getting any usefull pieces of information. The only entries I have in the log files are the following: /*log: /var/log/messages:*/ /Dec 5 09:53:35 hostname kernel: pid 33815 (imap), uid 0: exited on signal 11 Dec 5 09:53:39 hostname kernel: pid 33820 (imap), uid 0: exited on signal 11 Dec 5 09:54:22 hostname kernel: pid 33910 (pop3), uid 0: exited on signal 11 Dec 5 09:55:22 hostname kernel: pid 34071 (pop3), uid 0: exited on signal 11 Dec 5 09:55:47 hostname kernel: pid 34103 (imap), uid 0: exited on signal 11 Dec 5 09:56:13 hostname kernel: pid 34143 (pop3), uid 0: exited on signal 11 Dec 5 09:56:21 hostname kernel: pid 34164 (pop3), uid 0: exited on signal 11 Dec 5 09:56:26 hostname kernel: pid 34180 (imap), uid 0: exited on signal 11 Dec 5 09:56:40 hostname kernel: pid 34201 (imap), uid 0: exited on signal 11 Dec 5 09:56:49 hostname kernel: pid 34227 (imap), uid 0: exited on signal 11/ /*log: /mail/log/dovecot.log:* dovecot: Dec 05 10:13:46 Info: imap-login: Login: user=<test-amaury(a)mydomain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: Dec 05 10:13:46 Error: child 36621 (imap) killed with signal 11/ I'm also running a squirrelmail as a webmail and here when I refresh a folder content 3/5 times I'm getting an error: /Error: Connection dropped by IMAP server Query: SELECT "INBOX.Corbeille"/ I'm using Dovecot version 1.0.7 on a freebsd 6.2 and my dovecot.conf is: dovecot -n /# 1.0.7: /usr/local/etc/dovecot.conf base_dir: /mail/ log_path: /mail/log/dovecot.log protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /mail//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: POP3/IMAP ready. verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: maildir:~/Maildir fsync_disable: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota trash mail_plugins(imap): quota imap_quota trash mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: default_realm: tropik.nc passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen master: path: /mail/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir trash: /usr/local/etc/dovecot-trash.conf/ Thank you for your help!

[Dovecot] Questions about single intance storage
by Maria Arrea 03 Dec '11

03 Dec '11

Hello We are using dovecot 2.0.16 with mdbox+zlib. We are now testing SiS (Single Instance Storage) and I have 5 questions: 1º Is possible to "dedup" existing mdboxes? 2º Are attachments compressed with zlib if mdboxes already use zlib? 3º I have plenty CPU to spare, should I use a low value of mail_attachment_min_size , like 16KB ? 4º Can I "undo" SiS if I have problems? 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Thank you for your (great) support. Maria

[Dovecot] lda/sieve ignores quota from ldap
by Jens Meißner 03 Dec '11

03 Dec '11

Hello, I'm using Dovecot 2.0 with Sieve as MDA and Postfix as MTA. The Postfix delivery command is /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT". I have set a default quota with quota_rule = *:storage=1G. Some users should have a larger quota. This is defined in a ldap directory and I have set user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$. The imap_quota plugin shows the right quota for all users but the lda ignores the quota rule from ldap. If a user is over default quota but not over his ldap defined quota I get the following error message: From: Mail Delivery Subsystem <postmaster@[…]> Your message to <[…]> was automatically rejected: Quota exceeded (mailbox for user is full) The log file shows the following: Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full) Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: script /var/mail/[…]/dovecot.sieve failed with unsuccessful implicit keep (user logfile /var/mail/[…]/dovecot.sieve.log may reveal additional details) Nov 30 18:21:17 […] dovecot: lda([…]): msgid=<20111130172116.7F065A07D@[…]>: rejected: Quota exceeded (mailbox for user is full) dovecot.sieve.log: error: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full). What is wrong? What must I do to getting this to work? Thanks in advance.

[Dovecot] can not get t'bird to create folder

dovecot-2.0.16 on Fedora 15. thunderbird-8.0 I can access dovecot from thunderbird, imap maildir. But when I try to create a new folder, nothing happens. I'm not using LAYOUT=fs, so I have added, tb-extra-mailbox-sep, which didn't seem relevant anyhow. Any help appreciated. sean

[Dovecot] Authentication listener configuration
by Rainer Frey 02 Dec '11

02 Dec '11

Hi, I'm wondering about the authentication listeners that dovecot uses. In many configurations I see: service auth { unix_listener auth-userdb { Does any component of dovecot use this listener internally (lmtp, lda ...) and does that read the config and search for the listener, or is the exact name "auth-userdb" expected? Is this maybe dependent on the userdb? Which ones need it? And if I want to use postfix SMTP auth, should I define a second listener, or just re-configure that default one to postfix's needs? Also, in which cases do I need to define an auth-worker service, and a unix_listener for it? I don't find this in the documentation, if that's caused by my lacking search skills, please just send apointer. Thanks Rainer

[Dovecot] LDAP Authentication - Home Directory Creation
by Stephen Bowman 02 Dec '11

02 Dec '11

How does everyone handle this case? Users are authenticated by LDAP, and do not have accounts on the IMAP/dovecot server. When a new user is added to LDAP, the home directory (/home/newuser) needs to be created on the IMAP/dovecot server so dovecot can create the mail directories inside it (/home/newuser/mail/). Obviously I can come up with a few custom solutions, utilizing cron, but I feel like there's a cleaner solution out there. Thanks!
