[Dovecot] Correction of home and mail directory config
by "L. Grün" 22 Apr '12

22 Apr '12

Hello, after running dovecot for a while, I stumbled accross the warning, not to have mail and home directory settings point to one and same directory. Here is the output of dovecot -n: > dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.4 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps imap disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_max_userip_connections: 100 mail_privileged_group: mail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_full_filesystem_access: yes mbox_write_locks: fcntl dotlock namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: xxxx(a)xxxx.org mail_plugins: sieve log_path: auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail In "args: uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes" I should delete "Maildir". My question is: What files do I have to copy from /Maildir to the home directory /var/vmail/%d/%n/ ? Are there other side effects, I have to consider? Thank you very much for your help! Stefan

[Dovecot] sieve against ldap in Dovecot 1.2 vacation messeage
by Victor Oñate 22 Apr '12

22 Apr '12

Hi. I need configure "sieve" against ldap this is my file configuration dovecot.conf plugin { quota = dirsize:user sieve_dir = ~/sieve } protocol lda { mail_plugins = sieve } auth default { mechanisms = plain passdb pam { } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = nobody } I dont know what I have to put in dovecot-ldap.conf, ofcourse I have a atribut in LDAP by user with a vacation messeage "I'm out of office, please contact Mr. Black" this is dovecot-ldap.conf hosts = server auth_bind = yes ldap_version = 3 base = dc=dominio,dc=uk deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) The principal idea is keep the control the message by user with LDAP and Dovecot(IMAP). without touching the postfix configuration file is that possible, or am I dreaming. Thanks.. Victor Oñate.

If not, look at this page to configure logging http://wiki.dovecot.org/LDA That's your best chance at finding out the problem. I don't have virtual users, so I can't venture to say whether this is part of the problem. I know I had to fiddle with the mailer flags (you have "DFMPhnu9") to get my setup working, but I don't remember what I did or why. Try adding the "S" flag and see if that helps.

[Dovecot] migrate 15K users to new domain name
by Jan-Frode Myklebust 21 Apr '12

21 Apr '12

I need to migrate 15K users to a new domain name, and plan to use "dsync mirror" in the transition phase. Could someone confirm that this should work: Before giving users access to new-domain do a first sync to get all the stale data over: for user in $old-domain; do dsync mirror $user@old-domain $user@new-domain done Configure sieve vacation filter to forward all messages from $user@old-domain to $user@new-domain, and notify sender of changed address. Give users access to both new-domain and old-domain, and do a final sync. for user in $old-domain; do dsync mirror $user@old-domain $user@new-domain dsync mirror $user@old-domain $user@new-domain # twice in case the first was slow drop all messages for $user@old-domain Leave notice message for $user@old-domain saying he should use new-domain done Wait a few weeks/months, and then drop all users@old-domain. Does this look sensible? -jf

[Dovecot] mbox folders on-disc layout
by John Robinson 21 Apr '12

21 Apr '12

I'd like to change the on-disk layout for my mboxes from being ~/mail/foo/bar to ~/mail/foo.bar so that I can have folders containing both messages and subfolders, without having subfolders beginning with . and then having to do all the other fiddling with locations of index files etc. that goes along with LAYOUT=maildir++, and also leaving the filesystem layout looking sensible so my users see their mailboxes instead of the index and control files. Is this possible or do I need to patch something? (CentOS 6, dovecot 2.0.9) Cheers, John.

[Dovecot] Error in logs indicating broken files
by Steve Campbell 20 Apr '12

20 Apr '12

Still new to dovecot, I'm seeing a couple of errors in my log file indicating corruption of index files. Error: Corrupted index cache file/home/xxxxxx/mail/.imap/sent-mail/dovecot.index.cache: Broken virtual size for mail UID 67: 1 Time(s) Error: FETCH [] for mailbox ~/mail/sent-mail UID 67 got too little data: 6203 vs 7478: 1 Time(s) This account is used by multiple users, but it is not a shared account (haven't set any of those up yet - still new to me), so I would expect corruption possibilities when multiple users modify the account folders in some manner. Until I get some experience under my belt and make this a truly "shared" account, is there any way to resolve the corruption of the files mentioned above? Maybe just delete them? thanks steve campbell

[Dovecot] array code issue ?
by Tim Ruehsen 20 Apr '12

20 Apr '12

Hi, I just took a look into the dovecot 2.1 sources and just saw a possible issue in array.h. This code snippet as an example: #static inline void * #array_get_modifiable_i(struct array *array, unsigned int *count_r) #{ # *count_r = array->buffer->used / array->element_size; # return buffer_get_modifiable_data(array->buffer, NULL); #} array->buffer->used and array->element_size are of type 'size_t' which is 64bit on amd64 and others while 'count_r' is a 32bit value. At least, I see ugly warnings with -Wconversion (which I personally like to use). I know, it is unlikely that 'array->buffer->used / array->element_size' exceeds 32bit range. But then, dovecot's source is so well written, that the above code seems to disturb dovecot's code aesthetics. And who knows... in a few years (when we have THz and TBytes on our desktops) emails (and array sizes) might exceed everything that we think of today. Tim

Dear Timo, With Dovecot-2.0.16, 'doveadm mailbox list -A' will perform LDAP search with filter "(objectClass=posixAccount)", and get value of attribute 'uid' as mail user. Is it possible to custom the ldap filter and returned attribute name? For example: - LDAP filter: (&(objectClass=mailUser)(accountStatus=active)) - Returned attribute name: mail Did i miss something?

[Dovecot] old messages being delivered to blackberry
by Luc Belliveau 19 Apr '12

19 Apr '12

Several users are reporting old messages (sometime years old) are being delivered as new on their blackberry devices... I've confirmed that this happens to all blackberry users... I believe the problem is related to this error: Maildir: Expunged message reappeared, giving a new UID In fact, this is the only mail related error message on the server... the mail is stored on a glusterfs share, and I'm using director to prevent simultaneous access... although I wasn't able to get LMTP to work with Director... to simplify things, I've temporarily only enabled 1 dovecot server anyway, to get everything else working first... I'll fiddle with lmtp later... so right now only 1 server is accessing the mailboxes. Delivery is also done from that one server, from postfix. Possibly caused by GlusterFS, the indexes were still getting corrupted, even with only 1 server... so I've moved the indexes to a local directory on each server. I'm no longer getting index related errors... but the expunged error is still occuring... and the error seems to happen a few moments before the BB gets a bunch of messages... so it's very likely related. I would like to continue using GlusterFS if possible; I haven't found any indication that it is outright unsupported, as long as I'm using Director... I am using dovecot 2.0.16. Any help would be appreciated! Here is my configuration: # 2.0.16: /etc/dovecot/dovecot.conf # OS: Linux 3.1.9-1.4-desktop i686 openSUSE 12.1 (i586) auth_mechanisms = plain login disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = always mail_location = maildir:~/Maildir:INDEX=/var/indexes/%u mail_nfs_storage = yes mail_privileged_group = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = dict:user::file:/var/vmail/%d/%n/.quotausage sieve = /var/vmail/%d/%n/.sieve } postmaster_address = postmaster(a)bigdata.nb.ca service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } user = root } service lmtp { inet_listener lmtp { port = 24 } unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0660 user = postfix } } ssl_ca = </etc/postfix/smtpd.bundle ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota } protocol lmtp { mail_plugins = quota sieve } Luc

[Dovecot] Re-indexing of fts-solr not working
by Joe Beaubien 18 Apr '12

18 Apr '12

Hi, I am currently testing a 2.1 dovecot setup with fts-solr. Search speed is simply amazing. I decided to try to delete and rebuild the solr indexes, but i can't seem to rebuild them thru dovecot. At first, when telnetting to the imap server, the search initially built the index, and then subsequent searches are blazingly fast. 1- I deleted all the solr indexes with the following query: <delete><query>*:*</query></delete> 2- Flag the mailbox to be re-indexed: doveadm force-resync INBOX At this point, it doesn't work. When I telnet into the imap server, the searches always come back empty 3- I also tried a few other commands: doveadm fts rescan, doveadm index INBOX. Still no search results. Nothing seems to be appearing in the logs when I issue all the doveadm commands. What did I miss? Thanks, Joe

[Dovecot] namespace hierarchy
by Tom Fernandes 18 Apr '12

18 Apr '12

Hi, I'm migrating from Courier to Dovecot and would like to keep the original namespace and add two new ones on the new server. There's only one namespace in Courier which is "INBOX." . The seperator is "." In the new server I would like to have 3 namespaces (private, public, shared) and use "/" as separator. Is it possible to keep "INBOX." for private, so that the users mailboxes appear below the Inbox, but have public and shared on the same hierarchy-level like the Inbox? When I set prefix to "INBOX/" for private I get the users mailboxes below the Inbox, like I have it Courier now. But then at least the public, probably also the shared namespace doesn't work any more. I get "unknown subscription namespace" when trying to subscribe to some of the folders. My current configuration is: namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: public/ location: maildir:/var/vmail/example.com/public list: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:%%h/Maildir list: yes warm regards, Tom

[Dovecot] LMTP auth problem
by Cor Bosman 18 Apr '12

18 Apr '12

hey all, im getting the following error: Apr 14 14:29:44 lmtpdirector1 dovecot: auth: Error: passdb(scorpio,127.0.0.1): Auth client doesn't have permissions to do a PASS lookup: /var/run/dovecot/auth-userdb mode=0666, but not owned by UID 112(dovecot) Apr 14 14:29:44 lmtpdirector1 dovecot: lmtp(18298): Error: user scorpio: Auth PASS lookup failed My config. Director servers running both imap and lmtp with a matching set of real servers accepting imap/lmtp. Imap is working fine, and has been working fine for a while. Im trying to add lmtp to the director, but i cant seem to get that working. We're passing passdb on to the real servers. How does this work with lmtp? protocols = imap lmtp protocol lmtp { auth_socket_path = director-userdb } lmtp_proxy = yes # passdb check on real servers passdb { driver = static args = proxy=y nopassword=y } Cor

[Dovecot] Hints for a NFS-Setup
by Patrick Westenberg 18 Apr '12

18 Apr '12

Hi everyone, as I have often trouble with OCFS2 I want to switch to NFS but I'm not sure how to rebuild my cluster with regard to locking and indexing problems. By now my I have a four server configuration (there are another 2 servers for outgoing mail but they can be ignored): MTA(MX10) --(lmtp/socket)--> local dovecot --> iSCSI-LUN with OCFS2 MTA(MX10) --(lmtp/socket)--> local dovecot --> iSCSI-LUN with OCFS2 IMAP-User <--(imap)--> IMAP-Server1 (local dovecot) <--> iSCSI-LUN/OCFS2 IMAP-User <--(imap)--> IMAP-Server2 (local dovecot) <--> iSCSI-LUN/OCFS2 As far as I understood I will get poor performance if I'd just switch from OCFS2 to NFS (while keeping this configuration) with 4 hosts accessing the NFS-share and the index files on it and it is recommended to assign users to a specific host (http://wiki2.dovecot.org/NFS) I'm uncertain what's the meaning of "user" in this context. Is it an IMAP-User or every incoming mail? An IMAP-User assigned to a specific IMAP-Server is ok for me and I could store and profit from local index files. However, I want my incoming mailservers to be equally receiving mails. Both should accept mails for every mailbox but in this case I won't have local indexes. I would appreciate any hints. Patrick

[Dovecot] 487 imap-login processes - is this ok
by Götz Reinicke 18 Apr '12

18 Apr '12

Hi, recently I checked our mailserver for some more tuning and optimizing and noticed, that currently I do have 487 imap-login processes and I'm asking myself if that's o.k. We do have about 1.000 user in total and not everybody is currently logged in. May be this is o.k. but if not, what might I check? We run the dovecot package provided by redhat EL 5.8 dovecot-1.0.7-7.el5_7.1 Thanks for any comment or suggestion. Regards .

[Dovecot] returning a namespace location from userdb?
by Cor Bosman 18 Apr '12

18 Apr '12

hey all, is it possible to return the location of namespace from the userdb lookup? The code is a bit unclear about it. There seems to be a part of the docs saying: If you want to override settings inside sections, you can separate the section name and key with '/'. For example: namespace default { inbox = yes } The inbox setting can be overridden by returning namespace/default/inbox=no extra field I realize you can set 'location=' in the namespace, but we have mailbox locations that cant be expressed by the normal variable substitution vars in dovecot (dont ask). So we have a userdb that returns the correct mail location. This works fine. But im currently trying to implement a second namespace, and Im having trouble returning a mailbox location for this specific namespace from our userdb. Is this possible? If so, what would the userdb have to return exactly? namespace spam { type = private separator = / inbox = no prefix = Spam/ subscriptions = no list = yes hidden = yes } Regards, Cor
