[Dovecot] quota using wrong limits in user shared mailboxes
by Steffen Kaiser 13 Mar '14

13 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have setup a shared namespace to expose user's mailboxes to other users. That works well. Via ACLs users can access other users mailboxes. I have setup a quota for each user, that works well, too. The quota is tracked and new messages are denied, if the quota is exceeded. I do not find hints, if you need to setup something special for shared namespaces. http://wiki2.dovecot.org/Quota/Configuration shows how to track the quota and http://wiki2.dovecot.org/SharedMailboxes/Shared shows how to setup the namespace and ACL. If user1 shares "mailbox" to user2 and user2 copies a message there, the quota is tracked in the quota of user1 correctly. But to calculate if * LOGIN user2 ... * COPY 1 users.user1.mailbox fails with overquota or succeed, the quota limit of user2 is used instead of the quota of user1, whom "mailbox" belongs to. I have tested it with a. limit(user2) < limit(user1) b. quota(user1) + sizeof(message) < limit(user1) if quota(user1) + sizeof(message) > limit(user2), COPY fails with overquota. If I raise the quota of user2, the COPY succeeds. That means, although the target user's quota is not exceeded and won't after the copy, COPY fails. That seems to be wrong for me. The same will apply to the other way round, I guess: If the target user is over quota, but copying user's quota limit is greater than that, the COPY succeeds. [I have not tested it.] Hence, if you enable sharing, you undermine quota, because the other user can copy messages into a mailbox of an user overquota. Does other people see the same issue?

[Dovecot] Connection refused userdb lookup ..dovecot/auth-userdb
by Simon 13 Mar '14

Hi There, Ive taken a look at this and cant quite figure out what is going on here. I have tested all the SQL permissions, and also changed the unix_listener auth-userdb mode to 0666 (as instructed elsewhere to try and solve this issue), but cannot seem to work out what the issue is. Would someone be able to please point me in the correct direction here? Output of log + dovecot -n via this link: http://pastebin.com/wsUt0eEF # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.centos.plus.x86_64 x86_64 CentOS release 6.5 (Final) xfs Thanks Simon

[Dovecot] Turning on autocreate of maildirs - how?
by Graham Leggett 12 Mar '14

12 Mar '14

Hi all, I have a dovecot v2.2.7 installation, and I would like dovecot to autocreate the Maildir mailbox when those mailboxes don't exist. Following the instructions at http://wiki2.dovecot.org/MailboxSettings have had no effect, the errors below are reported. As soon as I create the Maildir manually with maildirmake fetching mail starts working fine, so all of the messages about the directory being ambiguous seem to be a red herring. Anyone know how to turn this on?

[Dovecot] Struggling with antispam
by Alan Chandler 12 Mar '14

12 Mar '14

I have a dovecot installation I am building on a raspberry pi for a mail server for the home. I am almost there, everything bar one thing is working. In simple terms dovecot is the authentication agent and the lda (using lmtp) for postfix. My maildir mailboxed at at /var/mail - location and accounts controlled by a small sqlite database. the uid for these mailboxes are 10001 and up and are not mapped to any account on the system. The sieve plugin is working and I have a default script which works to archive outgoing mail, returned via postfix sender_bcc_maps to user+saveout into a Sent subfolder organised by date. postfix also uses milters, to do spf, and dkim checking - and most importantly from this posts perspective passes all mail through dspam, adding an X-DSPAM-Signature header as it passes through. I plan to use another default sieve script to move mail based on the X-DPAM-Result header to move messages to the users Junk folder (when I can get antispam working). I want to use the antispam plugin to pick up users moving mail in and out of their Junk folder to train dspam. I initially tried using antispam's dspam backend. However I could not get it to work. I "think" the issue is that antispam is running with uid 10001 when it does this, and dspam will not process the message because it can't find this uid as a system user. But I am not sure. The approach I am trying now, is use the pipe backend to send mail to spam(a)chandlerfamily.org.uk or ham(a)chandlerfamily.org.uk - and via postfix manipulations get that to call dspam as user dspam. If I run as root and use sendmail -bv to check that it works I get a delivery report that shows that it would indeed arrive at dspam I have a file in /var/spool/dspam called group which has dpsam:shared:* In it so that all users share the same dictionary. However, when I try to make this work with anitspam, I keep getting failure, and I can't work out what is causing it. Maybe its again because I am running with uid 10001 when calling sendmail but I don't know. antispam config is plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash = Trash antispam_spam = Junk antispam_pipe_program=/usr/bin/sendmail antispam_pipe_program_args=-f;dspam(a)chandlerfamily.org.uk antispam_pipe_program_spam_args=spam(a)chandlerfamily.org.uk antispam_pipe_program_notspam_args=ham(a)chandlerfamily.org.uk } And what appears in syslog as a result of moving a mail from my INBOX to the Junk folder in thunderbird is ...

I would prefer to use dpsam backend directly if someone can tell me how to overcome the dspam rejection issues, but this alternative would also work (if a bit more convoluted to get mail to the correct place) if I could get antispam to call sendmail correctly.

[Dovecot] Disable/patch iOS7 Full Body Search
by Chris Laif 12 Mar '14

12 Mar '14

As mentioned in other posts [1], iOS7 Mail App uses a multi-folder full body search by default. As to my knowledge, this behavior cannot be disabled within the Mail App. Is there any way to disable/patch this behavior on the server side? My users complain that searching now takes 'forever'. They were happy with the old behavior (searching From/To/Subject only). I do NOT want to setup/maintain a dovecot FTS. I just want to have the 'old' behavior. Chris [1 ]http://blog.fastmail.fm/2013/09/17/ios-7-mail-app-uses-multi-folder-body-searches-by-default/ ("Our plan at FastMail is to detect iOS clients, and convert all searches into FUZZY searches.")

[Dovecot] Finding memory leaks
by Philipp Brüll 12 Mar '14

12 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I try to find a memory leak in a dovecot plugin that I develop. In order to find it, it would be helpful to print the total amount of memory that is currently allocated. This print could than spread over the source code and the memory consumption can be tracked. I've tried i_debug("pool size %u", (unsigned int)pool_alloconly_get_total_alloc_size(system_pool)); But that failed. Does someone has a good advice? I would like to avoid complex solutions like valgrind.

[Dovecot] Doveadm?
by Tommy Berglund 12 Mar '14

12 Mar '14

I have a question? Is it possible that with doveadm delete all but the last x-number of messages in a folder. For example to retain the last 200 messages in the folder. If it is possible, how do you do it? Something like "doveadm expunge -u jane.doe(a)example.org mailbox xxx" Thank you! -- //Tommy

[Dovecot] Can I create multiple sockets and listen on them in parallel.
by Alan Chandler 11 Mar '14

11 Mar '14

I currently have a setup which is postfix -> dovecot via lmtp over a unix socket. The socket is located at /var/spool/postfix/private/dovecot-lmtp I am calling dspam as a milter from postfix. However I am struggling with getting dspam knowing the correct user for the incoming mail, because after its been through the milter, the virtual alias maps etc end up turning it into my "dovecot" user name, and the two are not easily comparable. So instead I want to try and set up postfix->dspam->dovecot But I want to take it in easy stages, and therefore ideally would like to set up dovecot to listen on two sockets simultenously = one for the existing connection from postfix, and one for the future connection from dspam - preferably in the context of the /var/spool/dspam or /var/lib/dovecot directories That way I can continue to receive existing mail whilst sending a few test mails through dspam. Does 10-master.conf config file work that way? (debian configuration) can I change something like this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } } into this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } unix_listener /var/spool/dspam/dovecot-lmtp { mode = 0600 group = dspam user = dspam } } and still have dovecot work? -- Alan Chandler http://www.chandlerfamily.org.uk
