[Dovecot] stripping attachments
by Frank Cusack 08 Jan '10

08 Jan '10

there is a windows tool that strips attachments from emails on the server. i think it works for exchange. is there a tool or a way to do this for imap? i don't mean a mail filter that would strip them before the user sees them, i mean that the user could actively cooperate to reduce mail storage space, yet keep the original email on the server sans attachment.

[Dovecot] dovecot-1.2-sieve-0.1.3 compile error
by El Bundy 08 Jan '10

08 Jan '10

Hi, when I try to compile dovecot-1.2-sieve-0.1.3 on my NAS I get the error below and I have no idea why and who to fix this. I have a Qnap TS239pro NAS with a Intel Atom CPU running Linux. I installed and configured the ipkg dovecot packet (1.2.beta1). Getting mails via fetchmail and send them with deliver to the IMAP. Not I want to include sieve to filter mails as this is not part of the packet I need to compile this by my own. I installed all needed packets and download dovecot-1.2.beta1 and dovecot-1.2-sieve-0.1.3. I do configure and make for dovecot and ./configure --with-dovecot=../dovecot-1.2.beta1 and make for dovecot-1.2-sieve-0.1.3. All run without any problem till the error below.

[Dovecot] shared namespace problem
by Patrick Kaiser 08 Jan '10

08 Jan '10

Hi List, I've got a problem, setting up shared namespaces. I am trying to setup a Mailbox (Maildir) which is accessible for some users. (For example mailbox "sales" and only sales representive have access to it) Mailboxes can be found under /var/vmail/<username>, whereas <username> looks like foo.bar or peter.griffin ;) Now, if I connect via telnet, loggin in as foo.bar and run a03 SETACL foobar peter.griffin lwrxk everything seems fine. Under /var/vmail/foo.bar is a acl-file dovecot-acl-list Under /var/vmail/foo.bar/.foobar is a acl-file dovecot-acl The contents looks ok. Also there is a generated file /var/vmail/shared-mailboxes.db. But if i now loggin in as peter.griffin and setup command a03 LIST "" "*" or a03 LIST "" "#shared" I can not find any shared mailbox. Above you can find my actual configuration. I've tried several versions of location: under shared namespace, but without success. Hope someone has a clue and point me into the right direction.

[Dovecot] Dovecot Sieve: Vacation Recipient
by Lukas Kolbe 08 Jan '10

08 Jan '10

Hi! I tried to use the sieve vacation plugin, but we're facing a little problem: our user's addresses are <uid>@<domain>, and if they want to use imap and sieve, they can have a forward to <uid>@imap.<domain>. The return-path, and hence the address the vacation message is sent to, is then <uid>@<domain> and not the original sender of the message. Is there any way to circumvent this? Sending a vacation back to oneself doesn't really make sense here :) Oh, and happy new year and thank you all for this great piece of software! -- Lukas

Well, there might be scenarios, when a local user other than root may sniff the connection on localhost, but I think you have no such one. So to encrypt a connection from localhost to localhost is a waste of ressources. In case of Dovecot you'll need one extra file descriptior (and depending on your settings one extra process as well), plus the CPU time to actually do the encryption. > Yeah.

The webmail-frontend _is_ your client in the view of Dovecot. But since the cert is in /etc/ssl/certs, it should work, but if you validate the cert, the webmail may bark, because you access the SSL-cert with the CN "webmail.domain.gr" by another name "localhost". This is a sign of a man-in-the-middle attack, actually. BTW: Do your SSL IMAP/POP clients also use the name "webmail.domain.gr"? Otherwise they will get a warning as well, maybe each time they connect.

[Dovecot] First time Dovecot user, really impressed so far. What is best IMAP enabled webmail package to go with Dovecot?
by Stan Hoeppner 08 Jan '10

08 Jan '10

Greetings everyone, I'm new to the list as of today. I just installed Dovecot a couple of days ago for the first time, Debian Lenny Dovecot v1.0.15-2.3. So far I'm pretty impressed. I'm using mbox format with Dovecot auto-deciding to place mail in user home directories, which is great. It works very well with the Win32 Thunderbird 3 client over a small basic 100FDX switched net. I've got one list mail folder with 10,600 messages and server side body searching that folder via T-Bird is very quick, on the order of 5 seconds. It would probably be quicker if Dovecot threaded the search to use both CPUs, but pegging just the one CPU the search is still very darn quick. And this is on a dual P2-550 class machine with only 384MB RAM and a single 500GB 7200RPM SATA drive. I'd like to install a webmail package on the same host. I used Squirrelmail for this purpose many years ago and I wasn't wholly impressed with the user interface. I'm also not impressed by the fact that I regularly receive spam from compromised Squirrelmail hosts/accounts. I really like the look/feel of the Scalix Web Access AJAX based interface, but I can't/won't use Scalix as it's not supported on Debian, it has more features than I need, and the system requirements are a bit steep. So, what's the best FOSS IMAP enabled web mail front end with a modern look/feel? I'd like to run it on lighttpd, which I'm already using, not apache. Thanks in advance for any advice. My apologies if my first post is a little OT, but I figured there's probably no better place to ask about the best webmail front end for Dovecot than here. -- Stan

Does Dovecot Sieve plug-in support Dovecot 2.0? We have a few servers running Dovecot 2.0 beta1, but the Dovecot Sieve plug-in (version 0.1.4) won't compile against it. Is this on the Sieve TODO list? If so, when do you see it will happen? Thanks Wenjie

[Dovecot] Dovecot not delivering mail.
by Anthony Nedland 08 Jan '10

08 Jan '10

I get no errors when attempting to send or receive. However, my messages aren't showing up in the mailboxes. I am sending between users on the same server. This is my dovecot -n output ------------------------------------------------ # 1.1.11: /etc/dovecot/dovecot.conf Error: Error in configuration file /etc/dovecot/dovecot.conf line 1076: Unknown section type (section changed in /etc/dovecot/dovecot.conf at line 1038) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf ----------------------------------------------- I was under the impression that this would be an irrelevant message, as my actual dovecot configuration file is dovecot-postfix.conf rather than dovecot.conf. The logging shows login/logout and no errors. Thanks.

[Dovecot] auth, partially resolved
by Spyros Tsiolis 07 Jan '10

07 Jan '10

Hello people, After a lot of wading through the dovecot documentation (which btw, is excellent !, everything lies under "dovecot/doc/wiki"), I managed to authenticate a couple of accounts. For starters, I want dovecot to work as an imap/imaps box and nothing else. So , I went ahead and created a "passwd" file with two users. One user being my name (spyros) and plaintext password and the other user "postmaster" with encrypted password ("/etc/dovecot/passwd" shown) : --- spyros@webmail.domain.gr:{PLAIN}plainpassword postmaster@webmail.domain.gr:{SSHA}SSHAPassword --- Now, if I telnet to port 143 with both users, the system comes back with the following : --- [root@webmail dovecot]# telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- As I said, it allows login on port 143 for both users. So, the same for "postmaster". Now for port 993 : --- [root@webmail dovecot]# openssl s_client -connect webmail.domain.gr:993 [lots of SSL-related certificate information] * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- Again, the same for user "postmaster". I don't paste. So, everything is fine. However, I have an issue with the (?!) issued certificate. If I check the dovecot logs I find nothing. If on the other hand, I do the same check on the Horde application, It comes back with the following : --- * Trying protocol imap/notls, Port 143: SUCCESS - INBOX has 0 messages (0 new 0 recent) * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAIN[SERVERBUG] Internal error occurred.

However, I would like an opinion before I go ahead and bug them with this. Certificate was created with "dovecot/doc/mkcert.sh" and the relevant certificate file (can't recall its name at the moment). Any help would be appreciated. On the other hand, If I went too far with this I apologize and I'll try to find another way to resolve this. Thank you people, s.

Possibly a webmail service and a desktop imap client. It may be that both machines are trying to manipulate the uidlist at the same time, causing who knows that kind of corruption. This could maybe explain some of the coredumps im seeing in 1.2.7? This is on Debian/Lenny, using NFS spool and NFS control/indexes. Timo, you asked in private mail a few days ago if we're sure the filenames are forever unique. Im sure. I double checked it in the source code. The above filenames are timestamp_hostname.pid, and that seems pretty unique right? Regards, Cor

Note this is *not* the same issue as: - maildir: v1.2.7 and v1.2.8 caused assert-crashes in maildir_uidlist_records_drop_expunges() I applied those patches to my 1.2.8 installation before 1.2.9 was released and that immediately fixed the expunge crash, but the array_delete bug is still there. dovecot -n --------------- bash-3.2# /usr/sbin/dovecot -n # 1.2.8: /etc/dovecot.conf # OS: Linux 2.6.18-164.6.1.el5 x86_64 CentOS release 5.4 (Final) listen: * ssl_cert_file: /rci/local/certs/imapd-pop3d.pem ssl_key_file: /rci/local/certs/imapd-pop3d.pem disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_max_processes_count: 2048 max_mail_processes: 2048 first_valid_uid: 100 mail_location: maildir:~/Maildir:INDEX=/rci/nqu%h/dovecot:CONTROL=/rci/nqu%h/dovecot mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_drop_priv_before_exec: yes mail_executable(default): /rci/local/etc/convert-courier-imap.sh mail_executable(imap): /rci/local/etc/convert-courier-imap.sh mail_executable(pop3): /rci/local/etc/convert-courier-pop.sh mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: passdb: driver: pam args: dovecot userdb: driver: passwd -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

That would of course need a dict-ldap backend implemented, but it would be a generic way to solve this, if its API is good enough. > After another day of looking into this, I believe that there are two concerns to be addressed: 1. dovecot implementation: how dovecot/pigeonhole provides access to these external sources in a sane way. I do like the dict interface for this, which could keep LDAP url's (or SQL queries, etc) out of sieve scripts, and into nicely compartementalized configuration files. Being very ldap focussed at my site, I hadn't looked at dict before today. 2. sieve language: an extension which would allow scripts to get information from an external source. I'm asking the draft-ietf-sieve-external-lists authors a few questions about this. The end result would be something like what follows: Dovecot implementation (proposed): ------------------------------------- <dovecot.conf> dict { dict_sieve = ldap:/etc/dovecot/dovecot-sieve-ldap.conf } plugin { # TODO: proxy this dict? sieve_extsrc = dict } </dovecot.conf> then I'm not sure how you specify multiple hosts with the dict-sql format, so I'm using the postfix convention. there's probably a better way for dovecot. <dovecot-sieve-ldap.conf> map { name = responder_mode server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_mode result_scope = sub bind = no version = 3 } map { name = responder_text server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_text result_scope = sub bind = no version = 3 } map { name = forward_keep server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardKeep result_scope = sub bind = no version = 3 } map { # in this case we can have many responses name = forward_addresses server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardAddress result_scope = sub bind = no version = 3 } </dovecot-sieve-ldap.conf> Sieve language: --------------------- then with proposed new functions of the sieve language (all names plucked out of my head 2hrs ago, would have to think about the semantics some more): 1. a “:list” argument that expects a string-list 2. a “:extsrc” argument that expects an <ext-name: string> and returns a string-list 3. a “:extsrc1” argument that expects an <ext-name: string> and returns a string 4. a new test that uses information that is not in the message, say “arbitrary [comparator] string string” (syntax needs work) sample uses in scripts are then: 1. redirect to a mailing list sourced from ldap (or wheverver): # mailForwardAddress attribute can be present >=0 times redirect :list :extsrc “dict:forward_addresses” 2. decide whether to keep or discard forwarded messages (eg: after the above rule) # mailForwardKeep attribute should only be present once, if at all if arbitrary :is :extsrc1 “dict:forward_keep” “TRUE” { keep; } 3. decide vacation action and text based in information in an ldap dir: # mailResponderMode & mailResponderText attrs should only be present once, if at all if arbitrary :is :extsrc1 “dict:responder_mode” “alwaysreply” { vacation :days 1 :extsrc1 “dict:responder_text"; } if arbitrary :is :extsrc1 “dict:responder_mode” “holiday” { vacation :days 30 :extsrc1 “dict:responder_text”; } ... where the "dict:mapname" syntax would be dovecot implementation specific. could also support the URL & TAG-URI schemes as proposed by draft-ietf-sieve-external-lists. This would allow query URLs as a more general case, using whatever's configured in /etc/ldap/ldap.conf (or whatever the platform's ldap client lib uses). Doing this does raise some resource consumption concerns, hence there should probably be a means of restricting external queries to global scripts only (or sieve_before, sieve_after), and a means of providing timeout values, etc. eg: if arbitrary :is :extsrc1 “ldap:///o=myorg?mailForwardKeep” “TRUE” { keep; } I'll keep on thinking about the design, staring intently at the dovecot sources and http://wiki.dovecot.org/Design for another couple days before attempting to write some code to test this. Feedback on the design of both the sieve language extension, & dovecot interface very appreciated. Cheers, -Martin Foster

[Dovecot] Failed IMAP Login Attempts in Logs
by Carlos Williams 06 Jan '10

06 Jan '10

I had a user telling me that they can't login to the Postfix email server via Webmail (RoundCube) and I decided to see if I could locate this issue in the logs and understand if the user was simply using a wrong password credential and or something more serious. More than likely the person is just using a wrong password but in search of this on my logs, I don't understand why Dovecot doesn't log failed login attempts. When I attempted to login with a wrong password, I show the following in my logs: [root@mail log]# cat /var/log/maillog | grep 'Jan 5' | grep -i 'dovecot' | grep -i 'carlos' Jan 5 11:00:13 mail dovecot: imap-login: Disconnected: user=<carlos>, method=PLAIN, rip=::ffff:192.168.0.10, lip=::ffff:192.168.0.10 Is there a log level or something I am not searching for that will allow me to see failed or invalid logins for Dovecot (IMAP)? Thanks!

[Dovecot] Sorting in IMAP list command?
by Ronald Johnson 06 Jan '10

06 Jan '10

Hi All, I'm running Dovecot 1.2.9 and have noticed the IMAP list command does not appear to send a sorted list of folders with list command. For example on our Cyrus server I get a sorted list of folders (with INBOX listed first): 2 list "" "*" * LIST (\Noinferiors) "/" "INBOX" * LIST (\HasNoChildren) "/" "CalProject" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "Drafts" ... while on our Dovecot server I get seemingly random listing: 2 list "" "*" * LIST (\HasNoChildren) "/" "lsf" * LIST (\HasNoChildren) "/" "mrg" * LIST (\HasNoChildren) "/" "studiosysadmins" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "TriTeam" * LIST (\HasNoChildren) "/" "systemupdates" * LIST (\HasNoChildren) "/" "bb" * LIST (\HasNoChildren) "/" "nagios" * LIST (\HasNoChildren) "/" "server" ... Is this intentional, or have I done something wrong? I didn't see any option in the dovecot.conf to set the behavior of the list output.

[Dovecot] Dovecot quota not working
by Bruno Guimarães Sousa 05 Jan '10

05 Jan '10

Hi everyone, I'm trying to make quota to work in dovecot 1.0.rc15 in a Debian machine. Setting the limit to 1GB and starting to fill up the mailbox and nothing stopped me. It just kept growing and nothing happened. Restarted the service and nothing. I had already exceeded the 1 GB limit and nothing happens, the mailbox still goes bigger and bigger... The *"check_quota"* plugin for squirrelmail shows "0.0% of 1.0GB" in my browser. 1GB is exactly what it is defined in dovecot.conf by maildir. Is it necessary to configure something in postfix?

[Dovecot] imap default separator ignored?
by Harald Dunkel 03 Jan '10

03 Jan '10

Hi folks, I have configured the imap folder separator to '/' (see below). AFAIU the separator character does not affect the internal folder representation managed by Dovecot, but just the communication between client and imap server. Question is: What is supposed to happen if I try to create a folder named "a.b" in this configuration? Since '.' is not a separator character anymore, and since the client doesn't know anything about the internals of Dovecot, I do not see why Dovecot complains about an invalid character?

[Dovecot] Problems getting the antispam-plugin to work
by Malte Schirmacher 03 Jan '10

03 Jan '10

Hi List, i'm running the current debian lenny dovecot-version (dpkg says it's 1.0.15-2.3+lenny1) and i'm trying to get the antispam-plugin ('1.2+20090702-1~bpo50+3') to work. Unfortunately dovecot always says "antispam plugin not configured" moving spam into the spam-folder. My config: protocol imap { mail_plugins = antispam } plugin { antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash = Trash antispam_spam = Spam antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --deliver=;--user;%u } Thanks in advance Malte Schirmacher

[Dovecot] What auth ?
by Spyros Tsiolis 03 Jan '10

03 Jan '10

Hello people, First of all a Happy New Year and best wishes to you all. I've managed to setup dovecot v1.2.9 on a CentOS 5.4 system and I am now, trying to make it auth. I would prefer virtual users and only want to make the IMAP/ IMAPS part work. I don't need POP3 or anything else. The rest will be handled by another SMTP/POP3 application. Now, I almost managed to make dovecot auth a virtual user with his password. However, when it seems it has passed the auth stage (either via IMAP _or_ IMAPS), the command line kicks me out. Here's roughly what I did : 1. Created /etc/dovecot/users and /etc/dovecot/passwd 2. filled in a couple of usernames/passwords encrypted in MD5 format 3. Ran dovecot from command line (service dovecot start [after I created the service ofcourse]) 4. telneted to localhost via port 143 or 993 (with the help of openssl: "openssl s_client -connect the.system.name:993") 5. typed : . login username@fqdn <password> Something worth noticing for step "5". If I do this logging-in with the "user@fqdn" format, the systems kicks me out. I, then, check the latest on "/var/log/dovecot/errors" to find that the system does not complain about the auth. If I do the same logging-in but instead use "user@localhost" (and not the fqdn), the system fails the authentication stage and does _not_ drop me into the shell. Go figure !! Anyway. My question, in essence, is this; Which type of auth should I use ? The manuals (that i've been sinking my head for the last couple of weeks) suggest I should use PAM. PAM, I cannot understand. At the moment, I _think_ I am using MD5. Any pointers here ? I've been reading the /doc/wiki directory for quite some time until it made no sense to me anymore (too much info makes me loose perspective). Any help would be greatly appreciated. TIA, spyros

[Dovecot] disable lazy_expunge for some mailboxes?
by Frank Cusack 03 Jan '10

03 Jan '10

How to disable lazy_expunge for certain mailboxes? My problem is I have a public namespace, whose mail is on a different filesystem than user mails. Some users are allowed to expunge on this shared mailbox, but lazy_expunge is stopping that from working since the mail has to cross a filesystem boundary to make it into the lazy_expunge namespace (location is under the user's home directory). As a workaround can I run a daily cron job to remove messages with the \Deleted flag on them? If so how do I find them? thanks -frank

[Dovecot] Recalculate quota usage on demand
by Michael 02 Jan '10

02 Jan '10

I would a method for Dovecot to recalculate the quota usage and rewrite it to the quota DB (Called on demand by a non-Dovecot POP3 daemon) I don't want the line deleted in the DB as this would only recalculate next time the Dovecot LDA or IMAP handles a message, and I want to keep the data availability contiguous. Can this be done?

[Dovecot] nested folders

using both thunderbird and roundcube with dovecot IMAP, I can create all the folders I desire, but cannot create subfolders; I also cannot delete a folder once created. I get a very un-informative error message from each. Is there a special setting required to permit sub-folder creation? folder deletion?

[Dovecot] Using Push IMAP to trigger POP3 download
by Aaron Whitehouse 02 Jan '10

02 Jan '10

Hello all, I have an HTPC connected 24/7 to the Internet running Mythbuntu. I also have a web/email host that runs Dovecot for email and provides IMAP and POP3 access. I understand that Dovecot supports Push IMAP and I could, for example, use Thunderbird to connect to my email host to receive instant email as it arrives. I would like to add a Dovecot IMAP server on my HTPC (for increased storage, to aggregate multiple email accounts, to process messages with SpamAssassin and to provide a better webmail interface) and retrieve email from my webhost to my HTPC by POP3. To set up POP3 on my HTPC, I understand that the norm is to set a time interval (say, every 10 minutes) for clearing email. What I would prefer to do, if possible, would be to have Dovecot on my HTPC keep a Push IMAP connection with Dovecot on my webhost. When a new message is available on the webhost, my HTPC would be "pushed" a notification and it could do a POP3 download. This would allow it to clear emails with POP3 (and reduce storage requirements on my webhost), mean that I received emails instantly and not require me to have it poll for messages on a very-regular basis. Does anybody know if this is possible? As an alternative (not solving my space problem on the webhost, but solving the others), is it possible to set up Dovecot to "piggy back" off an existing IMAP server? In my example, my webhost does not offer good spam-checking and webmail. Would it be possible for me to set up a Dovecot server on my HTPC that received messages by Push IMAP, processed them with SpamAssassin (say, moving all of the spam messages to a subfolder) and provided a good web interface, all the while providing updates to the webhost's server? In some ways, this is almost more like an IMAP client than a server. I apologise if these questions are stupid! Happy New Year and thanks in advance, Aaron -- FSF Associate Member: 5632 http://www.fsf.org

[Dovecot] Deliver virtual user's mail to a specific namespace?
by Brian Schang 02 Jan '10

02 Jan '10

Hello: I have virtual users set up for the various mailing lists that I subscribe to. Everything has been working well in both Postfix and Dovecot. Postfix is configured to deliver to a specific mbox file within my mbox mail root. I can access retrieve and read email via Dovecot without any issues. Now I want to make my setup more robust and have these messages delivered to a maildir namespace. I have configured the LDA within the Postfix master.cf file: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} I have configured the 'dovecot' transport within Postfix in the transport file: test(a)lists.schang.net dovecot: In dovecot.conf I have set up the namespace as follows: namespace private { separator = / prefix = "Lists/" location = maildir:~/MailLists subscriptions = yes } I'm having a hard time specifying the "Lists/" namespace in my userdb passwd-file: test:{PLAIN}linux:2000:200::/home/brian::userdb_mail=maildir:Lists/test I can't get the userdb_mail portion to work. For this user, 'test(a)lists.schang.net', how do I tell Dovecot/deliver to put the message in the 'test' mailbox within the 'Lists/' namespace? I'd appreciate any insight. Thank you. -- Brian Schang

[Dovecot] Issue Authenticating to a new dovecot-postfix installation
by Anthony Nedland 02 Jan '10

02 Jan '10

(Apologies if this is a resend, but I thought I had received a bounceback message.) I have installed dovecot-postfix and postfixadmin on an Ubuntu 9.10 machine. The userdb and passdb are both mysql. If I set up a user in postfixadmin they are able to send. I can successfully telnet into the server remotely by name on 110 and 25. I'm not looking for any authentication encryption/ssl any of that, just POP3/SMTP. When I telnet into 110 I can enter a username with user [username] then when I do pass [password] I get -ERR Authentication failed. I know the user info is correct. When I set up an account in Outlook Express I get "There was a problem logging onto your mail server. Your Password was rejected:" Also saying -ERR Authentication failed.'. (0x800ccc90,0x800ccc92) So basically the same thing. I can attach the tutorial I used in as a .doc if that would help.

[Dovecot] Dovecot LDA with SetUID
by Michael 02 Jan '10

Has anyone been able to get Dovecot LDA working where each user has a different UID? All the howtos on the Internet I have found set the UID of a mailbox as fixed for all users. However I have tried to run it on the current SQL database we have (with different UID per user) and I get the following: Jan 1 16:25:40 HOST dovecot: deliver(EMAIL): Fatal: setgid(1000(stdusers)) failed with euid=8(mail), gid=12(mail), egid=12(mail): Operation not permitted I am calling this from Postfix with: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient}

[Dovecot] Quota with Dict + SQL not updating
by Michael 01 Jan '10

01 Jan '10

Hello all, I have a Dovecot server deployed with a MySQL back end. If the user logs in and there is no quota set for them in table 'quota', the system will automatically inset a line with their username and current messages/storage. However after this it fails to update the information when to reflect new messages coming to their inbox after the original insert of the information. It will only update the information when a user deletes a message. Why is it not updating this information every time their mail is checked with IMAP? Cheers, Michael

[Dovecot] Oracle SQL driver
by Alexander Bukharov 31 Dec '09

31 Dec '09

Hi all. Recently I was looking for an IMAP-server with Oracle support and unfortunatelly I couldn't find one. It was a surprise for me but there is no such functionality at all. So I've chosen an IMAP-server with most flexible and convinient architecture that was Dovecot-1.2.9 and written a driver for Oracle RDBMS support. I used Oracle Pro*C so a Pro*C preprocessor is needed to compile the driver. There is a lot of logging there that should be removed. It would be great if you consider to include this driver to mainstream so Dovecot will be the first IMAP server supporting Oracle as auth backend. All related files are attached. Cheers.

[Dovecot] A Dovecot Sieve spam filter question.

Hi, I'd like to make a filtering threshold for users to let them deal with spamassassin spam-level starred < 8 themselves, but spam-level starred higher than 8 should be discarded how can one do that with the "anyof" option ? the following doesn't work with a test email with "gtube", which scores > 999 : # require "fileinto"; if header :matches "X-Spam-Level" "\*\*\*\*\*\*" { fileinto "discard"; } and I think it would be nice to have not so many lines in the globalsieverc file.

[Dovecot] Hostname setting defaults
by Timo Sirainen 30 Dec '09

30 Dec '09

Any thoughts about the following? hostname setting currently defaults to system's host name, without the domain part. It's used (in v2.0): - dovecot-lda (new deliver): If -a parameter isn't specified and there's no Envelope-To: header, the destination address is generated as <username>@<hostname setting> - lda/lmtp: In generated Message-Id: headers ("dovecot-stuff@<hostname>") for rejects, vacation, etc. - lda/lmtp: in reject messages as part of MIME boundary, and also in "Reporting-UA: <hostname>; Dovecot mail delivery agent" header. - lmtp: In the protocol, e.g. "220 <hostname> Dovecot ready" or "421 4.4.2 <hostname> Disconnected for inactivity" - lmtp: In added Received: header Seems pretty clear to me that it should be host.domain.org, not just host. So I suppose I'll change that default. The other thing is postmaster_address. That's accidentally been postmaster(a)example.com in dovecot-example.conf and uncommented. So who knows how many installations have their postmaster address set to that.. I'm thinking of just commenting it out in next v1.2 release so admins needs to change that. But for v2.0 maybe there could be a good default for postmaster_address? "postmaster@<hostname setting>" I think? Because it's postmaster(a)host.domain.org instead of postmaster(a)domain.org, it might not be correct in most installations, but I'm thinking that maybe it's safer. Someone trying out Dovecot on testbox.biguni.edu probably doesn't want bounces going to postmaster(a)biguni.edu..

[Dovecot] dovecot-shared
by Frank Cusack 30 Dec '09

30 Dec '09

I'm confused about dovecot-shared. If the file exists, \SEEN flags are NOT shared? So if dovecot-shared exists, flags are actually private. The doc seems clear on this (albeit not worded very well). I only question it because intuitively you would think the opposite. If backwards compatibility is the reason for this reverse behavior, the file should have been named dovecot-private-flags. In fact that's a great name to stick a list of flags (one-per-line) that are private. -frnak

Re: [Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 30 Dec '09

30 Dec '09

Thanks for the reply. I won't be changing any files, or even accessing them, i'll simply be passing the filename along to "another system". I'm not allowed to change this other system or any of its interfaces. The other system has been in place and is "off limits" as far as changes go (I'm told). To make it simple, this other system needs to be notified of any flag changes on emails. So, when we detect a flag change (in our plugin), we need to pass the message filename along to this other system. I hope this makes sense...and again...i'm not justifying the need for it, but I have to play the hand i'm dealt....Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040-----Original Message-----From: "Timo Sirainen" [tss(a)iki.fi]Date: 12/29/2009 04:02 PMTo: "Tony Rutherford" CC: dovecot(a)dovecot.orgSubject: Re: [Dovecot] Retrieve Physical Message FilenameOn Tue, 2009-12-29 at 15:50 -0500, Tony Rutherford wrote: > Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm > overriding "update_flags":void my_mail_update_flags(struct mail > *_mail, enum modify_type modify_type, enum mail_flags flags)For this > email which is having its flags updated, I need to retrieve the > physical filename of the message.

The problem is that by the time you're trying to access the file, its flags may have already changed, which also means its filename could have changed. So even if you got it, your code would probably randomly fail. What exactly are you going to do with the filename? Maybe you should instead be opening the file with mail_get_stream() and doing something with the fd. This message is intended solely for the individual(s) to whom it is addressed.

[Dovecot] Mail storage creation fails with virtual users
by Scott H. W. Snyder 30 Dec '09

30 Dec '09

So I have recently set up dovecot with a virtual users dovecot.passdb file, but when I attempt to telnet in, it fails because my virtual users don't have proper permissions to create mailboxes. I don't want to have to create actual users for each email account. Any idea as to what to do?

[Dovecot] Install fails when libdir and libexecdir are the same directory

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using Dovecot 1.2.9.

[Dovecot] multiple attribute templates?
by Mariano Absatz 29 Dec '09

29 Dec '09

Hi, I've been using an attribute template for some time without any problems. My accounts are on an LDAP server and I have an attribute maildropPath which is the maildir path for the user relative to /home/vmail That is, user "mabsatz(a)example.org" has, in attribute maildropPath the string "example.org/mabsatz", meaning that the maildir is in /home/vmail/example.org/mabsatz This is configured like this (taken from http://wiki.dovecot.org/AuthDatabase/LDAP/Userdb) user_attrs = maildropPath=mail=maildir:/home/vmail/%$ pass_attrs = uid=user,userPassword=password,maildropPath=userdb_mail=maildir:/home/vmail/%$ and it works OK. Now I want to start using sieve and, since all accounts are virtual, I want to use a subdirectory "sieve" within the maildir to hold the scripts, so I need (I think) a userdb home to point to the same path... being a monkey I tried to imitate (or rather, extend) the previous configuration like this: user_attrs = maildropPath=mail=maildir:/home/vmail/%$,maildropPath=home=/home/vmail/%$ pass_attrs = uid=user,userPassword=password,maildropPath=userdb_mail=maildir:/home/vmail/%$,maildropPath=userdb_home=/home/vmail/%$ Alas... this didn't work... that is, apparently, the "home" attribute works OK (I got my scripts on the /home/vmail/example.org/mabsatz/sieve directory), but the "mail" attribute got lost and mail is being delivered to /home/vmail/mabsatz. Is there a way to use more than one attribute template AND that both use the same LDAP attribute? Otherwise, can someone think of a better way to do what I'm trying to do? I'm using dovecot 1.1.11 from the standard ubuntu 9.04 package (dovecot-imapd_1.1.11-0ubuntu4.1). -- Mariano Absatz - "El Baby" el.baby(a)gmail.com www.clueless.com.ar -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Real programmers use: cat > a.out http://xkcd.com/378/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- * TagZilla 0.066 * http://tagzilla.mozdev.org

[Dovecot] Deliver EX_TEMPFAIL's without giving any information
by Denis Khromov 29 Dec '09

29 Dec '09

Hi all. I've had a hard time trying to find out why deliver isn't working after I've updated dovecot from v1.11 to v1.2.8. It just gave me EX_TEMPFAIL without any info in the logs. My deliver was setuid-root. Once I've made a simple shell wrapper script for the deliver executable which saves deliver's stdout+stderr, I've found the reason: /usr/local/libexec/dovecot/deliver must not be both world-executable and setuid-root. This allows root exploits. See http://wiki.dovecot.org/LDA#multipleuids Did a 'chmod o-x deliver' and fixed groups/owners and now everything works as it should. I think this error message should go to log files, not just to stdout/stderr. And it's worth to describe this behaviour in the Wiki. Cheers, Denis

[Dovecot] dovecot -n output of (default) is confusing me
by john.blue＠cox.net 29 Dec '09

29 Dec '09

Hello, I'm new to dovecot and I've been taking my time examining what makes dovecot work. If I have imap and pop3 listed as protocols, dovecot -n outputs: mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 I don't understand why imap is listed twice once as (default), and the other without (default). As a secondary question, why would you want a default of imap as opposed to pop3? Thanks. John

[Dovecot] Log rotation?
by Beto Moreno 29 Dec '09

29 Dec '09

Hi people. I had read dovecot logging info, they say something about using log rotation to help us rotate our log, with this setup: # dovecot SIGUSR1: Re-opens the log files. /var/log/dovecot*.log { missingok notifempty delaycompress sharedscripts postrotate /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true endscript } Well, my question is simple, Do we need to restart the service each time logrotation runs? In my case, is wrong this? var/log/dovecot*.log { weekly rotate 8 notifempty missingok copytruncate create 600 root start 0 } I have 2 dovecot logs: dovecot-info.log dovecot.log dovecot-info.log is the biggest, 5MB by week, is to much? Do I have to change our log rotation to "daily"? Centos 5.4 updated, dovecot 1.0.7-7.el5, thanks!!!

[Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 29 Dec '09

29 Dec '09

Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm overriding "update_flags":void my_mail_update_flags(struct mail *_mail, enum modify_type modify_type, enum mail_flags flags)For this email which is having its flags updated, I need to retrieve the physical filename of the message. I see where using:mail_get_special(_mail, MAIL_FETCH_UIDL_FILE_NAME, &fname);...I can retrieve part of the filename, but without the ":2" and the flags part.Is there a method I can use to get the whole filename (without having to reassemble it myself). I've looked around, and I'm guessing it exists, but I don't see it offhand.Thanks,...Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040 This message is intended solely for the individual(s) to whom it is addressed.

[Dovecot] Design: Optimizations for high-latency storage backend
by Timo Sirainen 29 Dec '09

29 Dec '09

Mainly intended for future support of key-value (etc.) databases, but this is probably useful even for regular disk I/O. By using async I/O for disk access, the OS could more intelligently do seeks on disk to read the wanted data with less latency. Problem #1: Accessing message body while searching (e.g. SEARCH BODY). The idea is that searching wouldn't block. Caller would typically use mailbox_search_next_nonblock() function, which can return "try again later" result. Whenever search sees a query that could potentially block (e.g. SEARCH BODY, or searching a header that might not be cached), it goes into a slightly different search mode: - the whole search would typically be run from beginning to end immediately, and the search result state would be stored for each message. - whenever search runs into a situation where the result can't be determined without opening message body, it issues a prefetch command for that message, marks the result for the message as "incomplete", and continues to the next message - once the search is done with all messages, it starts replying to the caller. if the next search result is incomplete at the time, the search returns "try again later". optimizations: - probably there should be prefetch limit (a queue) so that only maybe 10 requests are actually pending at a time. - probably the whole search shouldn't run immediately. maybe it should stop after having 10 requests pending. - prefetch could return only the needed parts of the message, such as "only header" or "only body" (or in future something like "message without attachments") There would be a new call, something like mailbox_search_set_nonblock_callback() that specifies a function to be called when next search result is available. The callback then would continue the search. This is similar to how IMAP SEARCH is already implemented, except currently when mailbox_search_next_nonblock() returns "try again later", Dovecot simply adds a 0 second timeout after which it's called again (that's enough for Dovecot to do some other pending work). Problem #2: Accessing index cache while searching. Cache file is typically in memory or in low-latency disk already. Anyway something similar to #1 could be implemented for it. "Make sure cache x..y bytes in cache file have been read to memory" call or something. Problem #3: Fetching message body (and uncached fields). The nice thing about lib-storage's fetching API is that the caller already specifies what fields it intends to access in mailbox_search_init(). So this code can use a similar technique than searching: - callers only use mailbox_search_next_nonblock() - which keeps returning "try again later" until the message body has been read to memory - trying to access a field that's not specified in wanted_fields in mailbox_search_init() could be (optionally) treated as a programming error and cause a crash instead of a blocking wait. Problem #4: How to drop latencies between IMAP commands? For example a (stupid) client issues commands: a FETCH 1 BODY.PEEK[] a FETCH 2 BODY.PEEK[] ..etc.. You really don't want to a delay between each command. So what Dovecot code needs to happen is to start processing the next command while waiting for previous one to finish reading the body to memory. A lot of this actually already works as intended, but there are some cases that don't, such as FETCH + SELECT (see #5). Problem #5: Opening mailbox index. So if your indexes are also stored in high-latency disk, how do you optimize getting STATUS for each mailbox? Again, a similar idea than before: Create a new mailbox_open_nonblock() function that calls a given callback function when the indexes are read to memory. During the wait it can continue processing more STATUS commands (hopefully client sends them all at once, instead of waiting for each reply before sending next STATUS). .. I think that's all of the problematic cases that could cause blocking. And the solution is always the same: Use prefetching and "try again later" status code with a callback function to be called when it's ready. Luckily there are only two functions that need the above behavior, implementing async callbacks for all functions would have made programming it horrible. The main problem will then be to optimize what and how much to prefetch. For example in the cache file case, should the cache be read to memory when mailbox is opened, or should it be delayed until something is actually wanted to be read from it? Should all of it be read, or should Dovecot attempt to be smarter to reduce memory usage and I/O bandwidth, so e.g. if the cache is wanted to be accessed to 3rd last message, maybe just read the cache file beginning from that message to EOF? Transaction log files have a similar problem. Actually all of this is similar to how Dovecot attempts to cache them to memory when using mmap_disable=yes, so it's not really a new problem.

[Dovecot] Design: Mailbox list indexes
by Timo Sirainen 29 Dec '09

29 Dec '09

I drove over 2000 miles in recent days, so I had some time to think about future Dovecot things. :) Maybe for v2.1 or v3.0, whichever I happen to release next. Here's the first thought: The main idea behind mailbox list indexes was to make getting STATUS information for mailboxes from a single index file. The code was already written for Dovecot v1.1, but it was disabled because of bugs I never got around to fixing. It also was maybe a bit overdesigned to make it fast with thousands of mailboxes. There were two indexes: Mailbox UID -> name map index, and UID -> status info index. I don't think most people have that many mailboxes. Using two index files just makes the common case slower. So the new mailbox list index could be a single index (read/written to using the same index file API as for mails). Index's header would contain an ID -> string map. So basically an array of {uint32_t id, char nul-terminated-name[]} records. Each index record would contain: - mailbox UID number (32 bit) - ID number (32 bit), pointing to a string in the header. That'll be this mailbox's name. - parent mailbox UID (e.g. if parent's name is "foo" and our name is "bar", the mailbox is "foo/bar") - mailbox global UID (128 bit) - mailbox flags (\Noselect, \Nonexistent) - STATUS information: message/unseen counts, last-non-recent-uid (for recent count), uidvalidity, uidnext, highest-modseq - storage backend specific timestamps So typically the whole index would be read into memory and the mailbox tree would be generated based on the parent UID pointers. If there are any \Noselect or \Nonexistent mailboxes, they just have their GUIDs and STATUS info zeroed out. Each time a mailbox is created or renamed, a new name ID is added to the header with the given name. I don't think it's worth it to try to reuse old IDs. Unused names (after delete/rename) will be dropped sometimes later. Whenever STATUS information changes while accessing mailbox, the STATUS info is updated in mailbox list index. Also unless mailbox_list_index_dirty_syncs=yes (or something similar), the index can't be trusted by itself. So before trusting the index, Dovecot needs to check if the index is up to date by comparing the timestamps to what exists in filesystem. For example with Maildir there would be new/ and cur/ directories' mtimes. Then there's the problem of how to notice externally added/deleted/renamed mailboxes. It'll be immediately noticed if such mailbox is tried to be opened, but what about LIST replies? One possibility would be to refresh the list once when session begins and after that just have LIST return indexed mailboxes. Another would be to keep track of directory mtimes and keep stat()ing the dirs to see if something changes. The latter is probably more trouble than worth.. Besides caching LIST and STATUS replies, there's one additional thing I thought of that the mailbox list indexes will be useful for: atomic mailbox list updates. Even if the backend doesn't support e.g. atomic RENAME (such as Maildir++), this can be made practically atomic using the list index. CREATE, RENAME and DELETE commands begin by writing and committing a record to the mailbox list index about the change. Then they'll start the actual change, and finally write to the index that the change is complete. If it crashed in the middle, the next session would finish it. If another session tries to do a conflicting change before the change is finished, it would wait for the previous one to finish. (Probably practically the index would be write-locked and all changes would wait for previous ones to finish.) And the final functionality of this mailbox list index is for the future support of key-value (etc.) databases: The mailbox list index would be the authoritative list of mailboxes. It wouldn't be stored anywhere else.

[Dovecot] checking all folders for new mail (IMAP STATUS command)
by Florian Effenberger 29 Dec '09

29 Dec '09

Hello, I use Thunderbird as IMAP client and do a lot of server-side filtering with Sieve scripts. To be notified of new mails, I want to check all folders (a lot of them...) at once for new mails, and not only the inbox. According to http://kb.mozillazine.org/Checking_for_new_messages_in_other_folders_-_Thun… it should be sufficient to enable one setting -- given that the IMAP server returns the STATUS command correctly. I still run Dovecot 1.0 (from Debian 4.0), and it seems this version doesn't support the IMAP STATUS command, as I have to explictly query each folder with the second mentioned setting. What is the recommended way of checking all folders for new mails? Is there any server-side setting I can activate? Do newer versions of Dovecot support the STATUS command in the way Thunderbird expects it? Or does Dovecot even offer an option like the mentioned IMAP_CHECK_ALL_FOLDERS=1 and IMAP_ENHANCEDIDLE=1 in Courier? Sorry for my maybe dumb question... :-) Thanks, Florian

I am using Dovecot 1.2.9 "dovecot-1.2-sieve-0.1.14" and discarding email seems to work fine. The things I can think of are: 1) Wrong privileges for deleting. What user does procmail / deliver run as? 2) Old Bug in Sieve (http://www.dovecot.org/list/dovecot/2007-July/024290.html) 3) If it fails just sometimes, what is the difference between discarded and nondiscarded mails. If this does not turn up something, I do not have an idea what is going wrong. Only bugfix I then can you provide with, is not to discard but to move those files to a folder 'SPAM' and delete them by hand. Tobi

Hi, I'm currently running Dovecot 1.2.8 with dbox mailboxes. I've configured the use of shared mailboxes. I'm able to only see the top-level mailboxes: e.g. Inbox LogWatch Trash Sent but not LogWatch/Server1 LogWatch/Server2 Is this a know limitation of a bug? Rgds, N.

[Dovecot] sieve vs deliver -m
by Frank Cusack 29 Dec '09

29 Dec '09

I'm invoking deliver through postfix with a dovecot transport in master.cf, using the -m ${extension} argument. If I have no sieve script, or a sieve script with an implicit keep, the mail gets correctly filed into the -m mailbox. However if the sieve script has an explicit discard, this gets honored if it doesn't match another sieve action. Shouldn't -m take precedence? I would say that if an extension is present any other sieve action should be ignored, perhaps just sieve_before should be run then the message filed per the extension. -frank

[Dovecot] basic understanding of imap in dovecot
by dovecot＠paz.bz 24 Dec '09

24 Dec '09

I have always used a pop3 daemon, and switching to dovecot has been my introduction to imap. Imap is foreign to me. I am wondering if I am a little off-track here, and would like some clarification. My MTA (exim) delivers email to: /mail/user dovecot, sucks that mail from /mail/user TO /home/user/mail/<filenamesoffolders> dovecot IMAP further uses /home/user/mail/.imap/folders/{.index / .index.cache / .index.log} the mail folder which exim uses doesn't seem to get emptied by dovecot when it sucks the email into /home/user/mail/<filenamesoffolders> when using IMAP. If POP3 is used via dovecot, then it appears that the interaction is directly to the original exim folder and that it does indeed empty (or at least it has the "FOLDER INTERNAL DATA" entry). I suppose my question is, is there a way to have dovecot empty/parse the original exim mailbox so that the customer email isn't sitting in two spots, taking up double the space. This would be in the IMAP environment only, as POP3 seems to be fine. Any online references available to help a newbee understand IMAP? Thanks!

[Dovecot] Permissions errors while reading messages via IMAP
by Geoff Sweet 24 Dec '09

24 Dec '09

Greetings all, I have been trying to setup a new system using Postfix and Dovecot to manage email for a bunch of virtual domains. So far everything is great, and I am now at the point where I am trying to build a webmail interface for the system. I'm using RoundCube for now. The tutorial I have been working from is here: http://workaround.org/articles/ispmail-etch/ Which seems to be a decent enough read. At this point I can login without issue but I can't see any mail messages. When I login, dovecot throws errors like this: Dec 23 12:08:49 mail1 dovecot: auth(default): client out: OK 1 user=geoff.sweet(a)test.com Dec 23 12:08:49 mail1 dovecot: auth(default): master in: REQUEST 1 4312 1 Dec 23 12:08:49 mail1 dovecot: auth(default): master out: USER 1 geoff.sweet(a)test.com uid=5000 gid=5000 home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Effective uid=5000, gid=5000, home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir: data=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir++: root=/home/vmail/test.com/geoff.sweet/Maildir, index=, control=, inbox=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: imap-login: Login: user=<geoff.sweet(a)test.com>, method=PLAIN, rip=192.168.20.11, lip=192.168.20.12 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Disconnected: Logged out bytes=39/431 Dec 23 12:08:49 mail1 dovecot: auth(default): new auth connection: pid=4315 Dec 23 12:08:49 mail1 dovecot: auth-worker(default): sql(geoff.sweet(a)test.com,192.168.20.11): query: SELECT email as user, password FROM view_mailboxes WHERE email='geoff.sweet(a)test.com'; Dec 23 12:08:49 mail1 dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=192.168.20.12 rip=192.168.20.11 lport=143 rport=43878 resp=AGdlb2ZmLnN3ZWV0QHdob290aXMuY29tAGJvYjEyMzQ1 Dec 23 12:08:49 mail1 dovecot: auth(default): client out: OK 1 user=geoff.sweet(a)test.com Dec 23 12:08:49 mail1 dovecot: auth(default): master in: REQUEST 2 4311 1 Dec 23 12:08:49 mail1 dovecot: auth(default): master out: USER 2 geoff.sweet(a)test.com uid=5000 gid=5000 home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: imap-login: Login: user=<geoff.sweet(a)test.com>, method=PLAIN, rip=192.168.20.11, lip=192.168.20.12 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Effective uid=5000, gid=5000, home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir: data=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir++: root=/home/vmail/test.com/geoff.sweet/Maildir, index=, control=, inbox=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Namespace : Using permissions from /home/vmail/test.com/geoff.sweet/Maildir: mode=0700 gid=-1 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): open(/home/vmail/test.com/geoff.sweet/Maildir/dovecot.index.log) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /home/vmail/test.com/geoff.sweet/Maildir/dovecot.index.log) Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): open(/home/vmail/test.com/geoff.sweet/Maildir/dovecot-uidlist) failed: Permission denied Dec 23 12:08:49 mail1 last message repeated 2 times There is some permission issue that allows dovecot to deliver email to the /home/vmail location (I dislike this location and want to change it) via the dovecot LDA process, but then not be able to read it when accessed via IMAP.

[Dovecot] imap-login crashes after upgrade to Dovecot 1.2.8 Linux 64-bit
by Chris Wakelin 23 Dec '09

23 Dec '09

Hi all, We moved our Dovecot installation first of all to have all folders and inboxes on NetApps via NFS (with indexes local) then from a physical Solaris 8 4-way UltraSparc server running Dovecot 1.2.5 (32-bit) to a virtualised Ubuntu 8.04 64-bit server with a single virtual processor (in VMWare ESX 3.5) running Dovecot 1.2.8 (64-bit). Since the change, many of our users have experienced random disconnections when proxied in imap-login (either using the internal SSL proxy, or to an external IMAP server) and the error logs contain things like: > Dec 18 00:27:58 imap-login: Info: Disconnected: Connection queue full (auth failed, 1 attempts): user=<user0>, method=PLAIN, rip=<ip0>, lip=134.225.32.156, TLS > Dec 18 00:27:58 imap-login: Panic: file ioloop.c: line 39 (io_add): assertion failed: (fd >= 0) > Dec 18 00:27:58 IMAP 9486 <user1> <ip1> : Info: Connection closed bytes=224/1753 > Dec 18 00:27:58 IMAP 10116 <user2> <ip2> : Info: Connection closed bytes=82/707 ... > Dec 18 00:27:58 IMAP 10296 <user3> <ip3> : Info: Disconnected in IDLE bytes=44/435 > Dec 18 00:27:58 IMAP 10298 <user3> <ip3> : Info: Disconnected in IDLE bytes=263/1662 > Dec 18 00:27:58 dovecot: Error: child 5124 (login) killed with signal 6 (core dumped) (latest ip=<ip0>) > Dec 18 00:27:58 imap-login: Info: Aborted login (no auth attempts): rip=<ip0>, lip=134.225.32.156, TLS: Disconnected and a backtrace gives: > (gdb) bt > #0 0x00007ff1030ad095 in raise () from /lib/libc.so.6 > #1 0x00007ff1030aeaf0 in abort () from /lib/libc.so.6 > #2 0x00000000004112d5 in default_fatal_finish (type=<value optimized out>, status=0) at failures.c:160 > #3 0x0000000000411333 in i_internal_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=<value optimized out>, args=<value optimized out>) at failures.c:443 > #4 0x0000000000410996 in i_panic (format=0x6 <Address 0x6 out of bounds>) at failures.c:207 > #5 0x000000000041420e in io_add (fd=-1, condition=IO_READ, callback=0x404db0 <client_input>, context=0x6af000) at ioloop.c:39 > #6 0x00000000004059db in client_auth_failed (client=0x6af000, nodelay=true) at client-authenticate.c:103 > #7 0x0000000000405e07 in client_handle_args (client=0x6af000, args=<value optimized out>, success=true, nodelay_r=0x7fff571009af) > at client-authenticate.c:198 > #8 0x0000000000406214 in sasl_callback (_client=0x6af000, reply=SASL_SERVER_REPLY_SUCCESS, data=0x0, args=0x6361d0) at client-authenticate.c:277 > #9 0x000000000040eb13 in auth_client_input_ok (conn=0x75b6c8, args=<value optimized out>) at auth-server-request.c:196 > #10 0x000000000040dbf3 in auth_client_input (conn=0x75b6c8) at auth-server-connection.c:136 > #11 0x0000000000414aa8 in io_loop_handler_run (ioloop=<value optimized out>) at ioloop-epoll.c:208 > #12 0x0000000000413b9d in io_loop_run (ioloop=0x6552b0) at ioloop.c:335 > #13 0x0000000000408e81 in main (argc=2, argv=0x7fff57100c58, envp=0x7fff57100c70) at main.c:494 Up until this afternoon we had "login_process_per_connection = yes", and login_max_connections at the default (256). This evening I tried with "login_process_per_connection = no" with no problems, except more CPU load and needing to increase login_max_processes_count (and strictly speaking the max fds set with ulimit -n would need to be increased, though I didn't do that as it would have involved killing and restarting the master process - come back Solaris plimit!) Just after midnight, I switched back to "login_process_per_connection = no" and set "login_max_connections = 32" and managed to get core dumps enabled, hence the above! Apart from this problem, the virtual machine has been doing extremely well, so it's not CPU or I/O load related. I'm not sure whether the problem is caused by the switch from Dovecot 1.2.5 to 1.2.8, Solaris to Linux, physical to virtual, or 32-bit to 64-bit! Perhaps we changed too much at once, but it did mean we kept the service going while power was turned off in our main machine room last weekend ...

[Dovecot] expire db(s)?
by ben＠electricembers.net 23 Dec '09

23 Dec '09

with two separate dovecot/backend servers accessing one central mysql server, will it be ok to have them both use the same expires table? Or will that confuse the actual dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool.sh cronjob since some of the entries mailboxes won't exist locally? Ben

[Dovecot] qpopper to dovecot migration
by Jernej Porenta 23 Dec '09

23 Dec '09

Heya, We are in the process of migrating from qpopper to dovecot as POP3 server (and IMAP as well) and we hit the UIDL issue with dovecot. Qpopper uses its own algorithm to create UIDL values and if you set it up to write them down in the mbox file as X-UIDL, then dovecot can use them (pop_uidl_reuse = yes). But if you don't use that feature from qpopper, than X-UIDLs are missing and there is no way to create the same UIDL values. So, I was wondering if anyone else hit that issue and maybe knows how to address it (writing an extension or something)? Thanks in advance, regards, Jernej

[Dovecot] Dovecot Deliver CPU usage
by Aravind Divakaran 23 Dec '09

23 Dec '09

Hi All, We have upgraded the dovecot from 1.0 to 1.2.8. After upgradation we have noticed that dovecot deliver process is utilizing a lot of CPU. As a result the mailsystem will stop working. When we limit the no of procs in postfix for dovecot deliver the CPU usage will come down. But we are not facing this problem with the previous version. Below is the log files for dovecot when the error occurs write_full(/home/vmail/dhanbank.co.in/vinukumarvm/temp.server.be3e5a849a909847) failed: No space left on device dovecot: deliver(user(a)example.com): stat(/tmp/Dovecot Delivery Mail) failed: No space left on device But my system has 54gb of free space for root filesystem where tmp residing. Can anyone help me to solve this issue. Rgds, Aravind

[Dovecot] Openbsd Postfix-Dovecot-SASL
by thekat 22 Dec '09

22 Dec '09

Greetings all, I have a OpenBSD /Dovecot server at home running and sending / receiving email "internally" without issue.. Recently, I set up the same at our Parish, but one of our users wants to get their email externally. The user can read their email but has to "send" via the local ISP server.. The problem After much searching I have not found an answer to my question. I would like the user to authenticate to be able to "send" email "through" the server.. OpenBSD uses bsdauth by default in Dovecot.

[Dovecot] Dovecot v2.0 wiki
by Timo Sirainen 21 Dec '09

21 Dec '09

I forked the wiki to http://wiki1.dovecot.org/ is the old docs for v1.x http://wiki2.dovecot.org/ is the new docs for v2.0 For now wiki.dovecot.org points to wiki1, but once v2.0 is released I'll change it to point to wiki2. I symlinked the user directory, so users should stay synced between the wikis. The main reason for wiki2 is to be able to describe Dovecot v2.0's actual behavior everywhere and get rid of all the old v1.x specific settings. The wiki1 is already annoyingly bloated and confusing with information about v1.0 and then v1.1 and maybe even how it's still different in v1.2.. Now would be a good time to do any other larger changes, if anyone has suggestions. :) (Oh, and I haven't yet done any actual changes to wiki2..)

The main disadvantage of this way is executing external aplication on every RCPT TO command. If you'll decide to use perl consider using option perl_at_start to minimize aplication starting time.

[Dovecot] Released Pigeonhole Sieve v0.1.14 and ManageSieve v0.11.10 for Dovecot v1.2.9
by Stephan Bosch 21 Dec '09

21 Dec '09

Hello Dovecot users, Due to personal matters I haven't had time to do anything in the last few weeks. Before that I provided some pre-releases and since nobody indicated problems with those, I release them definitively now. I hope the shit storm has blown over, so that I can dedicate more of my time towards Pigeonhole development. The Sieve release involves a large architectural change, but also fixes quite a few small problems. The ManageSieve release is necessary to match Sieve API changes. Changelog Sieve v0.1.14: * Made the imposed limits on the number of redirects and the number of actions configurable. The settings are called sieve_max_actions and sieve_max_redirects. * Did a major rework of extension handling, making sure that no global state is maintained. This change was triggered by problems that global state info would cause for Dovecot v2.0, but it is also important for v1.2 as it significantly cleans up the library implementation. + Made LDA Sieve plugin recognize the deliver_log_format setting. + Message headers produced from user-supplied data are now RFC2047-encoded if necessary for outgoing messages. This is for example important for the :subject argument of the vacation action. + Added support for the $text$ substitution in the deprecated notify extension. + The subaddress extension now also accepts recipient_delimiter setting as an alias for sieve_subaddress_sep setting. This anticipates the recipient_delimiter setting in v2.0. - Fixed logging of mailbox names. It logged the converted mUTF7 version in stead of the original UTF8 version supplied by the user. - Fixed a minor memory leak in the multiscript support. - Fixed a bug in the recompilation of Sieve scripts. Made sure that scripts are only recompiled when the script file - or the symlink pointing to it - is strictly newer. Changelog ManageSieve v0.11.10: * This release contains adjustments to match changes in the Sieve API. This means that this release will only compile against Pigeonhole Sieve v0.1.14. - Fixed compilation of ManageSieve against CMUSieve. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.14.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.14.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.10.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.10.tar.gz.… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.9-managesieve-0.11.10.diff.… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.9-managesieve-0.11.10.diff.… Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new releases and don't hesitate to notify me when there are problems. Releases for Dovecot v2.0 are still under development... Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Dovecot vs Exim file locking
by Daniel Campos 21 Dec '09

21 Dec '09

Hi all: We're planning to deploy a large e-mail system storing maildirs in a NAS system through NFS. One of the options we're thinking on is using Dovecot+EXIM. As far as I've read in both project's documentation, both services implement locking allowing multiple servers to access the same maildirs in order to distribute the service load. However, I can't find any information explaining whether both locking mechanisms are compatible, whether any additional configuration is needed both in Dovecot and/or EXIM, or even whether any locking synchronization between both services is needed/recommendable at all. The only remote clue I've found is that, according to Dovecot docs: "Because Dovecot uses its own non-standard locking (dovecot-uidlist.lock dotlock file), other MUAs accessing the maildir don't support it." (but EXIM is not a MUA, anyway) Anyhow theoretically MailDir could even be considered free of locking problems, but I'm not sure of the real implications of putting together several Exim and Dovecot installations pointing to the same NFS filesystem. Any knowledge/experience/link/clue on this would be greatly appreciated. Thanks in advance, Daniel Campos

[Dovecot] deliver panics when handling mails bigger than some kByte
by Leon Meßner 19 Dec '09

19 Dec '09

Hi, i've just upgraded to dovecot-1.2.8 (from 1.2.4) and do now get the following errors when deliver gets hands on mails with some attachments. # tail -n 1 /var/log/messages Dec 14 19:00:36 mail3 dovecot: deliver(user): Panic: file istream.c: line 96 (i_stream_read): assertion failed: (stream->eof) The MTA is postfix running inside a FreeBSD 7.2-STABLE jail. The homes where deliver should put mails are mounted via NFS. As it works with small attachments perhaps this is related to the message size. However i don't get the "stale NFS file handle" error any more which i did under 1.2.4 (See thread that begins with: Message-ID: <20091016122519.GC6309(a)emmi.physik-pool.tu-berlin.de> ) Greetings, Leon

[Dovecot] dovecot: pipe() failed: Too many open files
by JW 19 Dec '09

19 Dec '09

In the past few months we've been having increasing problems with dovecot timing out pop3 logins. As best I can tell it gets to the point where it won't accept any new pop3 logins. The error in the mail log is: dovecot: pipe() failed: Too many open files I've researched this problem a number of times, usually I see suggestions to increase ulimit. I've done this a number of times, all the way up to: ulimit -n 8192 I've put that in the init script right above the daemon start line. So far it hasn't helped. In addition, when looking at lsof, it doesn't seem like we're anywhere near the actual limit. for example, last time dovecot only had 1032 files open. Does anyone have any idea what could be causing the error? Or what else I can try to figure this out?

[Dovecot] Maildir on NFS - attribute caching question
by Brandon Davidson 18 Dec '09

18 Dec '09

Hi Timo, We've been running Dovecot with Maildir on NFS for quite a while - since back in the 1.0 days I believe. I'm somewhat new here. Anyway... The Wiki article on NFS states that 1.1 and newer will flush attribute caches if necessary with mail_nfs_storage=yes. We're running 1.2.8 with that set, as well as mail_nfs_index=yes, mmap_disable=yes and fsync_disable=no. We have a pool of POP/IMAP and SMTP machines that are accessing the maildirs, and can't guarantee any sort of user session affinity to a particular host. We also mount our NFS shares with 'noac', which is what I'm writing to ask about. I'd like to stop doing that for performance reasons. Do you see any issues with taking that out of the mount options, given our environment? Thanks, -Brad

[Dovecot] lot's of timeouts
by Götz Reinicke - IT-Koordinator 18 Dec '09

18 Dec '09

Hi, since some time ago we do have a lot of "timeouts" connecting to our imap/po3 server. This week I switched the whole system to a new dual quadcore xeon, 24GB RAM, SAS2 RAID-10. (SUN Fire 4170) But the mailclients (mostly thunderbird and apple mail) still reporte the timeouts by accessing the mailboxes. The server is doing smtp, imap/pop3, webmailsystem and spam/antivirus-checking all together. (RH EL 5, sendmail, horde, mysql, mailscanner, spamassassin) We use the original RH dovecot-1.0.7, mbox-format and mailboxes up to 4 GB ... (historicaly grown ...) So where to start debugging the imap/pop3 timeouts? What information may I provide, which doc may I read? Thanks for helping me to find and fix the problem.

[Dovecot] v2.0.beta1 released
by Timo Sirainen 18 Dec '09

18 Dec '09

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta1.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta1.tar.gz.sig Now that v2.0 is in beta stage I don't expect anything big to change anymore. The configuration and the APIs shouldn't change in non-backwards compatible ways. There are still bugs left to be fixed and some small features to be implemented, but I'd like to have people start testing it more. The biggest unimplemented "feature" is how to convert v1.x configuration easily/automatically to v2.0. Either the old config file should be translated to new one, or Dovecot should be able to read the old config file as-is. I think I like the translation better, so that people won't still be using v1.x configuration when v2.1 arrives and drops v1.x support. Largest changes since alpha3: - if some IP address is failing authentications, all auth attempts from the IP are delayed increasingly. a successful auth drops the delay. max delay is 15 seconds. this is enforced by auth process, so it works across different connections/processes/protocols. - lib-storage plugin API changed. processes handling multiple users now support different plugins for different users. - expire plugin's settings work a bit differently now: http://hg.dovecot.org/dovecot-2.0/rev/46691becc45e - post-login scripting works again, see http://dovecot.org/list/dovecot/2009-December/045139.html - Tons of fixes

Hi all We are planning to upgrade Dovecot from production version 1.0.10 to latest version 1.2.9 Users are using maildir style mailboxes with ~20 GB of messages on SLES10 server. Upgrade will be done by installing new server and then migrating mailboxes from old on new server. Since dovecot-uidlist file have new format and index files have changed in v1.1, what must be done to have new Dovecot v1.2 working properly with old v1.0 maildirs? Thanks, regards Ivica Glavocic

Imagine of a web server running the administration interface, that is not even the IMAP server (I know I can install only common dovecot components) or imagine to write a OSX/Windows Administration tool (I would like to write a Xcode/PyOBjc tool). Anyway, I’ll give a try to module hmac. Andre

[Dovecot] Why dovecot does not want to read my acl file?
by Lukas Haase 17 Dec '09

Hi, Simple Scenario: Shared namespace and a specific UNIX group should have access to it. System is Debian lenny (stable). # cat /etc/dovecot/dovecot.conf [...] namespace public { separator = . prefix = Shared. location = maildir:/var/mail/shared } mail_executable = /usr/local/sbin/dovecot-imap-fix.sh mail_drop_priv_before_exec = no #just to make sure [...] # dpkg -l | grep dovecot ii dovecot-common 1:1.0.15-2.3+lenny1 secure mail server that ii dovecot-imapd 1:1.0.15-2.3+lenny1 secure IMAP server that # cat /usr/local/sbin/dovecot-imap-fix.sh #!/bin/sh cat /var/mail/shared/.Office/dovecot-acl > /tmp/dovecot-$USER env >> /tmp/dovecot-$USER ACL_GROUPS=`groups $USER | tr ' ' ','` export ACL_GROUPS exec /usr/lib/dovecot/imap $* # ls -la -R /var/mail/shared/ # (cut the .,.. in output) /var/mail/shared/: total 28 drwxrwx--- 5 root office 4096 Dec 15 15:53 .Office drwxr-xr-x 2 root root 4096 Dec 14 16:55 cur -rw-r--r-- 1 root root 23 Dec 15 07:46 dovecot-acl -rw-r--r-- 1 root root 0 Dec 15 07:42 dovecot-shared drwxr-xr-x 2 root root 4096 Dec 14 16:55 new drwxr-xr-x 2 root root 4096 Dec 14 16:55 tmp /var/mail/shared/.Office: total 24 drwxrwx--- 2 root office 4096 Dec 15 09:53 cur -rw-r--r-- 1 root root 52 Dec 15 15:53 dovecot-acl -rw-rw---- 1 root office 0 Dec 15 07:42 dovecot-shared drwxrwx--- 2 root office 4096 Dec 15 09:53 new drwxrwx--- 2 root office 4096 Dec 15 09:53 tmp # id peter uid=1000(peter) gid=100(users) groups=51683(office),25783(ssh_users),100(users) # Now I log in as peter but I my client (latest TB 2) does not display the office folder. In the log it claimes that it is not able to open the acl file what really can NOT be true: Dec 15 15:56:05 mail dovecot: IMAP(peter): acl vfile: no access to file /var/mail/shared/.Office/dovecot-acl I tried: * su peter: Access no problem! * ps aux: The process is running as peter * As you can see I have debugging code in my dovecot-imap-fix.sh which successfully prints out the content of the ACL file to /tmp/user-peter I can't image that, it seems as if it is not true. By the way: As soon as I change the mail_executable to /usr/local/sbin/dovecot-imap-fix.sh I get this message and have absolutely no clue why: # /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecotid: dump-capability: No such user . # Which dump-capability? Which user? Does anybody have an idea what could be wrong here? Thank you very much, Luke

[Dovecot] Filing to public folders
by Cajus Pollmeier 17 Dec '09

Hi all, I'm currently playing with a setup which might replace my current cyrus imapd one with dovecot. Currently I'm stuck with trying to file messages that got to the user "lists" to the public namespace' System folder (public/System) with sieve. Dovecot claims "Permission denied", and I tried several debugging techniques to get the cause - without a result right now :-( Thanks, Cajus 8<-------- /var/log/mail.info Dec 16 21:40:51 ferdi dovecot: deliver(lists): sieve: using sieve path for user's script: /home/lists/.dovecot.sieve Dec 16 21:40:51 ferdi dovecot: deliver(lists): sieve: opening script /home/lists/.dovecot.sieve Dec 16 21:40:51 ferdi dovecot: deliver(lists): sieve: executing compiled script /home/lists/.dovecot.sieve Dec 16 21:40:51 ferdi dovecot: deliver(lists): acl vfile: reading file /var/dovecot/public/.System/dovecot-acl Dec 16 21:40:51 ferdi dovecot: deliver(lists): sieve: msgid=<3044.1260989392(a)ferdi.test.net>: failed to store into mailbox 'public/System': Permission denied Dec 16 21:40:51 ferdi dovecot: deliver(lists): Namespace : Using permissions from /var/dovecot/mails/lists: mode=0700 gid=-1 Dec 16 21:40:51 ferdi dovecot: deliver(lists): sieve: msgid=<3044.1260989392(a)ferdi.test.net>: stored mail into mailbox 'INBOX' Dec 16 21:40:51 ferdi dovecot: deliver(lists): sieve: execution of script /home/lists/.dovecot.sieve failed, but implicit keep was successful 8<-------- /home/lists/.dovecot.sieve require ["fileinto"]; if header :contains "From" [ "root(a)test.net", "logcheck(a)test.net", "root(a)ferdi.test.net", "logcheck(a)ferdi.test.net" ] { fileinto "public/System"; stop; } 8<------- /var/dovecot/public/.System/dovecot-acl user=lists lrwstiekxa authenticated lr 8<-------- dovecot information Dovecot version 1.2.8 (Backport on debian lenny 1:1.2.8-1~bpo50+1) system> dovecot -n # 1.2.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-trunk-amd64 x86_64 Debian 5.0.3 ext3 log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/cert/ferdi.cert.pem ssl_key_file: /etc/cert/ferdi.key.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_access_groups: publicmail mail_privileged_group: mail mail_location: maildir:/var/dovecot/mails/%u mail_debug: yes mbox_write_locks: fcntl dotlock mail_plugins: acl namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: public/ location: maildir:/var/dovecot/public:INDEX=/var/dovecot/mails/%u/public list: children lda: postmaster_address: postmaster(a)test.net mail_plugins: acl sieve auth_socket_path: /var/run/dovecot/auth-master debug: yes auth default: passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 432 user: root group: mail plugin: acl: vfile sieve: ~/.dovecot.sieve sieve_dir: ~/sieve antispam_signature: X-DSPAM-Signature antispam_signature_missing: error antispam_spam: SPAM antispam_dspam_binary: /usr/bin/dspam antispam_dspam_args: --deliver=;--user;%u antispam_mail_tmpdir: /tmp antispam_mail_sendmail: /usr/sbin/sendmail antispam_crm_binary: /bin/false antispam_signature: X-CRM114-CacheID
