[Dovecot] dsync core dump

25 Oct '13

Dear all, We're slowly progressing towards migration, and now run into dscyn dumping core when trying to sync mailboxes from the old imap server. Needless to say that not one byte get's transferred. On the old.server all I see is a correct login. This is what we get for one example user: server:~# doveadm -v -D backup -R -u USER imapc: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib01_acl_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_quota_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so: undefined symbol: quota_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_zlib_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so: undefined symbol: i_stream_create_deflate (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(USER): Debug: auth input: USER system_groups_user=USER uid=XXXX gid=YYYY home=/home/USER /etc/dovecot/proxy-userdb doveadm(USER): Debug: Unknown userdb setting: plugin//etc/dovecot/proxy-userdb=yes doveadm(USER): Debug: Effective uid=XXXX, gid=YYYY, home=/home/USER doveadm(USER): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=yes, list=no, subscriptions=yes location=maildir:~/Maildir doveadm(USER): Debug: maildir++: root=/home/USER/Maildir, index=, control=, inbox=/home/USER/Maildir, alt= doveadm(USER): Debug: acl: initializing backend with data: vfile doveadm(USER): Debug: acl: acl username = USER doveadm(USER): Debug: acl: owner = 1 doveadm(USER): Debug: acl vfile: Global ACL directory: (none) doveadm(USER): Debug: Namespace : type=shared, prefix=shared/%u/, sep=, inbox=no, hidden=no, list=children, subscriptions=no location=maildir:%h/Maildir:INDEX=~/Maildir/shared/%u doveadm(USER): Debug: shared: root=/var/run/dovecot, index=, control=, inbox=, alt= doveadm(USER): Debug: acl: initializing backend with data: vfile doveadm(USER): Debug: acl: acl username = USER doveadm(USER): Debug: acl: owner = 0 doveadm(USER): Debug: acl vfile: Global ACL directory: (none) dsync(USER): Debug: Effective uid=XXXX, gid=YYYY, home=/home/USER dsync(USER): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=yes, list=no, subscriptions=yes location=imapc: dsync(USER): Debug: imapc: root=, index=, control=, inbox=, alt= dsync(USER): Debug: imapc(old.server:PORT): Looking up IP address dsync(USER): Debug: imapc(old.server:PORT): Connecting to IP dsync(USER): Debug: imapc(old.server:PORT): Starting SSL handshake dsync(USER): Debug: imapc(old.server:PORT): SSL handshake successful dsync(USER): Debug: imapc(old.server:PORT): Server capabilities: IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ MAILBOX-REFERRALS NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES IDLE AUTH=PLAIN ANNOTATEMORE dsync(USER): Debug: imapc(old.server:PORT): Authenticating as cyrus for user USER dsync(USER): Debug: imapc(old.server:PORT): Authenticated successfully dsync(USER): Debug: acl: initializing backend with data: vfile dsync(USER): Debug: acl: acl username = USER dsync(USER): Debug: acl: owner = 1 dsync(USER): Debug: acl vfile: Global ACL directory: (none) dsync(USER): Debug: Namespace : type=shared, prefix=shared/%u/, sep=, inbox=no, hidden=no, list=children, subscriptions=no location=maildir:%h/Maildir:INDEX=~/Maildir/shared/%u dsync(USER): Debug: shared: root=/var/run/dovecot, index=, control=, inbox=, alt= dsync(USER): Debug: acl: initializing backend with data: vfile dsync(USER): Debug: acl: acl username = USER dsync(USER): Debug: acl: owner = 0 dsync(USER): Debug: acl vfile: Global ACL directory: (none) Segmentation fault (core dumped) Here is the output of dovecot -n #

[Dovecot] Replication not happening on 2.2
by Lucas Rothamel - Eye Catching Webdesign 24 Oct '13

24 Oct '13

Hello, first - thanks for the help in getting dovecot 2.2 compiled and installed on Debian. I have Dovecot 2.2 running now on two servers, and to test replication, I am polling mail on one server whilst the other creates mail regularly from crontab output. I have replication set up, but nothing at all is appearing on the other server, and I do not have any dsync / doveadm messages in /var/log/mail.log any more. With 2.1, these two used to spam many errors into mail.log. Any hints? Here is my dovecot-n output: # 2.2.6: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 ext4 auth_mechanisms = plain login cram-md5 disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/%d/%n/Maildir mail_plugins = " notify replication" mail_privileged_group = mail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { mail_replica = remote:vmail@mydomain quota = maildir:User quota quota_rule = *:storage=1GB replication_full_sync_interval = 1 hours } protocols = imap pop3 service aggregator { fifo_listener replication-notify-fifo { mode = 0600 user = vmail } unix_listener replication-notify { mode = 0600 user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service config { unix_listener config { user = vmail } } service doveadm { user = vmail } service replicator { process_min_avail = 1 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = quota postmaster_address = sysop@mydomain } Thanks, Lucas -- Lucas Rothamel Eye Catching Webdesign info(a)eye-catching-webdesign.de - www.eye-catching-webdesign.de You know, we go to the gym to keep the body fit.

[Dovecot] mailbox sharing with mdbox
by NOC WVNET 24 Oct '13

24 Oct '13

Hello, i want to know if it's possible to use mailbox sharing with mdbox. I have done a setup with maildir where it's working fine but with mdbox I'm only able to subscribe the shared folder but there are no messages in it. (maybe a problem with the namespace) I'm running dovecot 2.2.6 [deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2.patched main ] on Debian Wheezy Kind regards Stefan

Please do not start some flame war around this ! I've been ordered to set up such server and I KNOW there are probably security holes but nothing's perfect so a starting point is necessary *Thank you for any infos*

[Dovecot] Odd Feature Request - RBL blacklist lookup to prevent authentication
by Marc Perkel 23 Oct '13

23 Oct '13

I would like to have a list of IPs (hacker list) that I can do a lookup on so that if anyone tries to authenticate to dovecot they always fail if they are on my list. I have the list - and the list is available as a DNS blacklist. I'd like to have it work with both local IP lists or RBL lookup. The idea is so hackers from known IP addresses never succeed. If Dovecot provides the feature I have about 1/2 million IP addresses of known current hackers to block. Anyone else interested in this?

[Dovecot] fstat() errors on /srv/mail/<username>/dovecot.index.log

Dovecot version 2.1.7 Ubuntu 12.04.3 LTS Kernel 3.2.0-35-generic x86_64 I'm not sure exactly when this started occurring, but sporatically users report issues receiving email, having email saved to "Sent," etc. Looking in dovecot.log, I see the following errors: 2013-10-16 09:53:20 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=27434, secured, session=<PnoiBtzoBgB/AAAB> 2013-10-16 09:53:20 imap(user1): Info: Disconnected: Logged out in=93 out=846 2013-10-16 09:53:21 imap(user2): Info: Disconnected: Logged out in=3616 out=495 2013-10-16 09:53:24 imap-login: Info: Login: user=<user3>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=27436, secured, session=<jE5kBtzoBwB/AAAB> 2013-10-16 09:53:24 imap(user3): Info: Disconnected: Logged out in=93 out=819 2013-10-16 09:53:33 imap(user4): Error: fstat() failed with file /srv/mail/user4/dovecot.index.log: No such file or directory 2013-10-16 09:53:33 imap(user4): Error: fstat() failed with file /srv/mail/user4/dovecot.index.log: No such file or directory 2013-10-16 09:53:33 imap(user4): Error: fstat() failed with file /srv/mail/user4/dovecot.index.log: No such file or directory 2013-10-16 09:53:33 imap(user4): Error: fstat() failed with file /srv/mail/user4/dovecot.index.log: No such file or directory 2013-10-16 09:53:33 imap(user4): Error: fstat() failed with file /srv/mail/user4/dovecot.index.log: No such file or directory 2013-10-16 09:53:33 imap(user4): Error: fstat() failed with file /srv/mail/user4/dovecot.index.log: No such file or directory 2013-10-16 09:53:41 imap-login: Info: Login: user=<user3>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=27438, secured, session=<UDJlB9zoCAB/AAAB> 2013-10-16 09:53:41 imap(user3): Info: Disconnected: Logged out in=93 out=819 2013-10-16 09:54:12 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=27440, secured, session=<6bI5CdzoCQB/AAAB> 2013-10-16 09:54:12 imap(user1): Info: Disconnected: Logged out in=93 out=846 2013-10-16 09:54:12 imap(user5): Info: Disconnected: Logged out in=736 out=7064 2013-10-16 09:54:15 imap-login: Info: Login: user=<user6>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=27442, secured, session=<t+FnCdzoCgB/AAAB> 2013-10-16 09:54:15 imap(user6): Info: Disconnected: Logged out in=95 out=902 2013-10-16 09:54:20 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=27444, secured, session=<c/q1CdzoCwB/AAAB> 2013-10-16 09:54:20 imap(user1): Info: Disconnected: Logged out in=93 out=846 2013-10-16 09:54:24 imap-login: Info: Login: user=<user3>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=27446, secured, session=<nOb3CdzoDAB/AAAB> 2013-10-16 09:54:24 imap(user3): Info: Disconnected: Logged out in=93 out=819 These errors are not confined to a single user, and do not occur with the same frequency. I originally was running the Dovecot shipped with the default Ubuntu repositories (don't remember which version, but it was 1.*) and used a backport to upgrade to 2.1.7 to see if that fixed it. It did not. Any ideas why this is happening?

[Dovecot] doveadm: Fatal: open(/dev/tty)
by Dan Langille 22 Oct '13

22 Oct '13

I received this message today, and remembered, you can't do that... $ doveadm pw -s SHA512-CRYPT Enter new password: doveadm(dan): Fatal: open(/dev/tty) failed: No such file or directory </pre> It seems if you have no tty, you can't create a password. Surely there is a better way to do this? Looking at the code, it's trying to open the tty and turn off echo. For the record: FreeBSD 8.4-RELEASE-p3 And yes, there is no console. I'm attached to a FreeBSD jail from the host system, directly via the ezjail-admin console command. # w 6:52PM up 18 days, 23:34, 0 users, load averages: 0.96, 0.57, 0.46 USER TTY FROM LOGIN@ IDLE WHAT # Ain't nobody there.. -- Dan Langille - http://langille.org/

by Asmaa Ahmed 22 Oct '13

22 Oct '13

Hello, I am trying to use postfix/dovecot as mail server to be the imap storage for my voicemail system.For that I installed postfix and dovecot and trying to follow the instructions in this post http://etel.wiki.oreilly.com/wiki/index.php?title=Storing_Voicemail_on_an_I… I should add a master user for Asterisk to your IMAP server that has access to all user's mailboxes and as per the instructions, I should edit auth section in dovecot.conf which I can't find! Is there something wrong or should I add this section by myselfAlso I don't have dovecot.masterusers, should I create it? $/etc/dovecot$ /usr/sbin/dovecot -n# 2.0.19: /etc/dovecot/dovecot.conf# OS: Linux 3.2.0-31-virtual x86_64 Ubuntu 12.04.3 LTS mail_location = maildir:~/Maildirmanagesieve_notify_capability = mailtomanagesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihavepassdb { driver = pam}plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve}protocols = imap pop3 sieveservice auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix }}ssl_cert = </etc/ssl/certs/dovecot.pemssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUMssl_key = </etc/ssl/private/dovecot.pemuserdb { driver = passwd}protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10}protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh}protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r} Thanks.

[Dovecot] Dbox group file permissions
by Chris Lasater 21 Oct '13

21 Oct '13

Hi everyone, I feel like I am missing something obvious here. I have dovecot up and running and every piece of mail is given user read/write permission. I see the option mail_gid, but I do not see anyplace to set the group permissions. I see the below wiki talking about new home directories getting their permission from the parent directory, but this does not seem to work. Any assistance would be appreciated. http://wiki2.dovecot.org/SharedMailboxes/Permissions I changed the group permissions on the parent directory, and used rm -rf to delete the user directories, then logged in again so it was recreated. [user@dovecot ~]$ sudo ls -la /mnt/home/imapd/domain.example.net/ total 24 drwxr-x--- 6 imapd imapd 4096 Oct 21 17:35 . drwxr-xr-x 46 imapd nagios 4096 Oct 21 16:55 .. drwx------ 3 imapd imapd 4096 Oct 21 16:59 user1 drwx------ 3 imapd imapd 4096 Oct 21 17:35 user2 Setup Mail is written in dbox format CentOS 5.9 dovecot 2.2.6 NFS with director Mail Configs mail_home = /mnt/home/imapd/%d/%n mail_location = dbox:/mnt/home/imapd/%d/%n mail_uid = imapd mail_gid = imapd Thanks, Chris
