[Dovecot] spamc can't seem to call /usr/lib/dovecot/deliver
by Troy Vitullo 25 Oct '12

25 Oct '12

Hi, My server uses a system comprised of postfix, dovecot and dspam to filter and deliver mail. Postfix used the following flags in calling spamc and dovecot: flags=DRhu user=dovecot:secmail argv=/usr/bin/spamc -u ${recipient} -e /usr/lib/dovecot/deliver -d ${recipient} after an upgrade from Debian lenny to squeeze we were able to get everything working except spam filtering. Spamassassin is able to judge whether the mail coming in is spam but everything stops there. In mail.err I see: pamc[3608]: exec failed: Permission denied spamc shows the same thing in syslog: exec failed: Permission denied postfix delays the email: postfix/pipe[3607]: 50DEFF180EE: to=<[mail]>, relay=dovecot, delay=1.7, delays=0.07/0.01/0/1.6, dsn=4.3.0, status=deferred (system resource problem) Here are the permissions for deliver: -rwsr-x--- 1 root dovecot 865084 May 25 2011 /usr/lib/dovecot/deliver Here are the relevant groups: s1:~# grep dovecot /etc/group secmail:x:119:postfix,spamd,dovecot dovecot:x:111: here's the dovecot user: s1:~# grep dovecot /etc/passwd dovecot:x:108:111:Dovecot mail server,,,:/usr/lib/dovecot:/bin/false here's dovecot -n: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 6.0.6 base_dir: /var/run/dovecot/ protocols: imap imaps pop3s pop3 ssl_cert_file: /etc/ssl/certs/s1.troyvit.com.cert ssl_key_file: /etc/ssl/private/s1.troyvit.com.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: no verbose_ssl: yes 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_location: maildir:%h/Maildir/ mbox_write_locks: fcntl dotlock 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_enable_last(default): no pop3_enable_last(imap): no pop3_enable_last(pop3): yes pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls, oe-ns-eoh pop3_logout_format(default): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(imap): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(pop3): top=%t/%T, retr=%r/%R, del=%d/%m, size=%s namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)sphere.local auth_socket_path: /var/run/dovecot/auth-master mail_plugin_dir: /usr/lib/dovecot/modules/lda/ mail_plugins: sieve auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: dovecot passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: dovecot plugin: sieve_global_path: /etc/dovecot/default.sieve sieve: /srv/%d/mail/%n/%n.sieve Many thanks in advance for any advice you can give.

[Dovecot] dovecot auth against AD on samba4
by Carsten Laun-De Lellis 24 Oct '12

24 Oct '12

Hi group I am currently running a mail server on ubuntu 11.04 with postfix 2.8.5, dovecot dovecot 2.0.13 and openldap 2.4.23. I have now read about sogo and I am thinking about installing it because of it's native outlook support capabilities. The ZEG appliance wouldn't be an option for me because I use a virtual server from a provider where I can't install my own vm or even an iso. When I go thru the documentation there is a part with installing OpenChange based on samba4. As far as I understood the OpenChange authentication is against the samba4 AD. Actually there is no support in syncing the AD against an OpenLdap Server and I would have to change the OpenLdap port because the AD is listening on port 389. To change the port wouldn't be a big deal, but what i was thinking about to run the dovecot auth also against the samba 4 AD. I searched around on the internet but didn't find a doc yet how to do that. Does anyone here could provide me with a link or a how-to ? Thanks very much in advance.

[Dovecot] Clarifications on Pigeonhole and MySQL lookups
by Sandro Tosi 24 Oct '12

24 Oct '12

Hello, we're scouting if it's possible to use Pigeonhole (currently v0.3.1, as this will be provided with an upcoming Debian package) with MySQL dict lookups with the mail setup we're designing. Our (main) goals are: 1. store the filters on the database 2. allow each user to enable/disable any of the filters set we provide (it's a static set of some general filters, available to all the users; we're currently not providing the possibility to users to write their own filters) For point 1) we already see[1] that's possible, but it uses the map construct that might not fit with our current database structure: we have a domain table (storing the domain info) and a mailbox table (storing the mailbox info, but the username is composed by the local part, stored in this table, and the domain part is a FK to the domain table, using an id). Do you think it's possible to run a join query on domain+mailbox to retrieve the mailbox_id needed to query the table for the filters? Or do we have to create the filter table and store the local(a)domain.ext info there ("relaxing" the integrity relationships between tables)? How do we specify which filters are enabled for any given user? We originally thought of an "Enabled" field on the filter table, but in the example in the doc[1] I hadn't seen a way to do that: it seems like the filter list is specified in the proxy definition - am I wrong? How can we do that? [1] http://hg.rename-it.nl/dovecot-2.1-pigeonhole/file/e9ed5d5cef4b/doc/script-… I think it's enough for now, maybe additional questions will arise going deeper in details :) Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

[Dovecot] Maildir hardlinks
by Benedetto Vassallo 23 Oct '12

23 Oct '12

Hello list, Excuse me for my poor english. I have updated on a test server dovecot 2.0.13 to dovecot 2.1.1. All works fine, but with the new version it seems that dovecot don't do hardlinks when deliver a message to multiple users. I have checked my config and the only rule I can see aboout that is maildir_copy_with_hardlinks = yes in /etc/dovecot/conf.d/10-mail.conf My mail location config is mail_location = maildir:~/MailDir:LAYOUT=fs I tryed using lmtp directly issuing 'telnet localhost 24' and sending a test message to 3 recipients. Then issuing a 'ls -il' in the "new" directory of that users, I saw the inode was not the same. I rechecked my config and take a look in the wiki and in the list for someone who had the same problems, but found nothing. Maybe I did something wrong, but I can't understand what. Can you help me?

[Dovecot] index files created improperly in dovecot 1.2.16
by john roman 23 Oct '12

23 Oct '12

Greetings, It seems to be a problem that ive seen occasionally on the web with few results as to a solution, but im experiencing it as well. Namely, dovecot creates index logs for users with a 600 permission, when it should create with a 700 permission. My indexes are stored in /var/indexes with the directory at 777 permission, the users are identified in MySQL. The error is as follows: Oct 23 09:03:13 mailer01 dovecot: POP3 (johnr(a)testing.com) stat(/var/indexes/j/johnr(a)testing.com/.INBOX) failed: Permission denied (euid=10509305(x10509305) egid=81607(pg199275) missing +x perm: /var/indexes/j) the permissions of /var/indexes/j are 700, owned by the euid and egid effectively. the only file that does not have this permission is in /var/indexes/j/johnr(a)testing.com/.INBOX/dovecot.index.log, at 600.

[Dovecot] 76Gb to 146Gb [Resolved]
by Spyros Tsiolis 23 Oct '12

23 Oct '12

Hello all, I would like to thank you all for your kind replies and feedback in regards to migrating from a smaller hdd to a bigger one (namely from 72gb to 146gb). I finally found a painless way of doing this. Since I believe that this is still an off-topic post, if anyone is interested in the solution i've adopted for this, let me know by replying to me privately. If, however, you don't mind me posting here, let me know. Many many thanks go to Alexander Hoogerhuis, the "mad Norwegian" :-) who helped me on this too much to describe here. Alex, you are a true sport. Thank you again people. All the Best, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis
