[Dovecot] BUG: segmentation fault in auth

Hi I'm getting segmentation fault in Dovecot 2.2.11. This happens when trying to do a user lookup by "doveadm user". The machine is running Arch Linux on i686 on ext3. dovecot -n (I took this when running the previous version that works) # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.12.9-x86-linode56 i686 auth_cache_size = 32 k default_client_limit = 500 default_process_limit = 50 default_vsz_limit = 128 M log_timestamp = "%Y-%m-%d %H:%M:%S " mail_gid = vmail mail_location = sdbox:~/sdbox mail_privileged_group = mail mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes location = mailbox Archive { auto = create special_use = \Archive } mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { auto = create special_use = \Junk } mailbox Sent { auto = create special_use = \Sent } mailbox Trash { auto = create special_use = \Trash } prefix = separator = / subscriptions = yes type = private } passdb { args = /etc/dovecot/deny-users deny = yes driver = passwd-file } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_script_size = 1M sieve_quota_max_scripts = 10 sieve_quota_max_storage = 10M } postmaster_address = postmaster@<domain> protocols = imap lmtp sieve service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } process_min_avail = 1 service_count = 1 vsz_limit = 64 M } service imap { process_limit = 256 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 vsz_limit = 64 M } service managesieve { process_limit = 128 } ssl = required ssl_ca = </etc/ssl/myCA/certs/ca.cert ssl_cert = </etc/ssl/myCA/certs/imap.cert ssl_key = </etc/ssl/myCA/private/imap.key userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n driver = static } protocol lda { mail_plugins = " sieve" } protocol imap { mail_max_userip_connections = 30 } protocol lmtp { mail_plugins = " sieve" postmaster_address = postmaster@<domain> } This is the error I get: # doveadm user ... doveadm(root): Error: userdb lookup(...): Disconnected unexpectedly field value This appears in logs: Mar 08 00:18:40 kernel: auth[15182]: segfault at 4 ip 0805dbbd sp bfd87ec0 error 4 in auth[8048000+4b000] Mar 08 00:18:40 dovecot[15177]: auth: Fatal: master: service(auth): child 15182 killed with signal 11 (core dumped) Mar 08 00:18:40 systemd-coredump[15227]: Process 15182 (auth) dumped core.

[Dovecot] How to run a program with mail_filter plugin
by Stanislas SABATIER 07 Mar '14

07 Mar '14

Hi, I'm using mail_filter plugin but I don't want it to launch a script but a program I wrote instead. In 10-master, if I put the absolute path to my program in the plugin settings ie : (…) service mail-filter { executable = /usr/local/bin/mail/my_email_filter (…) But I've got the following error from Dovecot : dovecot: master: Error: service(mail-filter): Initial status notification not received in 30 seconds, killing the process h ow do I need to configure the service to launch my program ? Thanks, Regards, Stan. --------------------------------------------------------------- Stanislas SABATIER s.sabatier(a)pobox.com ---------------------------------------------------------------

[Dovecot] no sieve with lmtp_save_to_detail_mailbox=yes
by Dennis Kuhn 06 Mar '14

06 Mar '14

i have a problem with sieve and lmtp_save_to_detail_mailbox = yes. If the mailbox "detail" exists everything works fine, but if the mailbox detail does not exist then sieve does not work. The .dovecot.sieve.log file says sieve: info: started log at Mar 06 14:28:47. error: msgid=<531877EE.7070806(a)heinlein-support.de>: failed to store into mailbox 'test2': Mailbox doesn't exist: test2. I think this is the reason why no sieve script is executed, but why is sieve here involved? Is there any relation between lmtp_save_to_detail_mailbox=yes and sieve or is this a bug? The same sieve file works with the same mailaddress without mailextension, so the sieve script is not the reason for the failure. I am using dovecot version 2.2.12 Dennis Kuhn -- Heinlein Support GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-57 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

Hello, i added a existing MAILDIR as a Public Namespace and i can subscribe to this Namespace without a problem. I can access every folder except the INBOX. Thunderbird just shows a GREY "INBOX". Is there any way to access the INBOX of a maildir? Thanks Dieter Knopf

[Dovecot] Still no emails since Feb. 6
by Steve Campbell 06 Mar '14

06 Mar '14

I checked my settings on the dovecot mailman page, and although my account was set to "disable" email, after changing it and attempting to have the list resend my password, I'm still not seeing emails. The last time I received emails, the outgoing server for the list was sent from the IP 193.210.130.67. Is that still correct? I've checked my logs to see if there's anything blocked, and I don't see anything. I've checked my access file and firewall, and nothing is blocked there. I'm not sure why my account settings showed "disabled", but it sounds like email was either bounced back to the list or my server is in some type of outgoing list to prevent sending to me. I'm at a loss. Is there any way an admin can check for me, please, to see if there's a problem they might spot? Thanks, steve

[Dovecot] Pigeonhole Sieve Extprograms Plugin
by dovecot＠voidptr.de 06 Mar '14

06 Mar '14

Hi, I upgraded to Dovecot 2.2.9 from Debian's wheezy-backports today (which should contain the "sieve_extprograms" plugin and thus also the vnd.dovecot.{pipe,filter,execute} capabilities. However when I add require "vnd.dovecot.filter"; to my sieve script via managesieve, the server reports error: require command: unknown Sieve capability: 'vnd.dovecot.filter' What am I missing and what should I do to get pipe/filter/execute to work? postconf -n attached.

[Dovecot] whole user mailbox read only
by Francesco 06 Mar '14

06 Mar '14

Hello, i was browsing the dovecot wiki for some documentation related to the use of ACLs but i couldn't find an answer. i'm in the need to prevent users from deleting emails, yet being able to add new content via imap, what i mean is that a user should be able to create an email in its mailbox (maildir actually is used), but once the email is there the user shouldn't be able to delete it. do you know if there is a way to accomplish this for each subfolder on a Maildir environment? Thanks in advance Francesco

[Dovecot] Shared Namespace and correct location
by Dieter Knopf 05 Mar '14

05 Mar '14

Hello again, i still have problems using a Shared Namespace in my configuration. I'm using Dovecot 2.2.9. mail_location = maildir:/home/vmail/%d/%n/MAILDIR:INDEX=/home/vmail/%d/%n/INDEX/ namespace inbox { type = private separator = / prefix = inbox = yes } This works create. But: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/vmail/%%d/%%u/MAILDIR/shared:INDEX=/home/vmail/%d/%u/INDEXS/%%u subscriptions = no list = children } I'm still not sure how i can see a shared mailbox on a different account. I can add ACL rules and dovecot is adding SQL-Entries to the user-shares table. The dovecot-acl-list file is created too, hope this is okay (vfile + SQL) But i can't see the shared folder on the target account. I tried many location-pathes, but not sure how i can add the right folder. There must be a problem with %%d and %%u. Thank you very much, Dieter
