[Dovecot] dsync: convert only mbox in /var/mail to maildir?
by Jeff Simmons 26 Apr '12

26 Apr '12

I'm migrating an old UW pop server to a new Dovecot server. The old server did not allow mail to be stored on the server, so only mbox files exist in /var/mail, with nothing in /home/$user. I'd like to copy the /var/mail directory over to the new server and then use dsync to convert the mbox files and put them in /home/$user/Maildir, but every permutation of the command line I've tried dies with a variation on can't find/write either /var/mail/mail or /home/$user/mail, seems it won't deal with mbox files without an associated mail directory. Can dsync be used for this kind of conversion, or should I look elsewhere for conversion utilities? Thanks for helping a noob who can't traverse a wiki without leaving a trail of breadcrumbs. -- Jeff Simmons jeff(a)j-simmons.net Simmons Consulting - Network Engineering, Administration, Security

[Dovecot] 2.1.x changes and dsync -- Wiki suggestion
by Jeff Kletsky 26 Apr '12

26 Apr '12

There are a couple things that show up on the Upgrading/2.1 wiki page that would be useful to have on pages describing dsync (Tools/Dsync, Migration/MailFormat, Tools, perhaps others): * dsync was merged into doveadm * You can't dsync 2.0.x to/from 2.1.x That second point is especially "interesting" to me as it seems that Apple MacOS X Server is still on 2.0.16, at least from what I see on opensource.apple.com. I was planning on migrating mail off the current server onto my friend's new MacMini, but I'll have to figure out how to "downgrade" the mail jail to a 2.0 version, it seems. Thanks for all the great work, Jeff

[Dovecot] Reading Mutt mboxes from Thunderbird
by Leonardo M. Ramé 26 Apr '12

26 Apr '12

Hi, I'm a user of Mutt, and before moving to Thunderbird I'm trying to share mboxes between them. To do this, I installed Dovecot to create an IMAP server in my local machine, to serve mutt mboxes to be read by Thunderbird. So far, I can read my inbox from /var/mail/%u, but in mutt, I have many folders in ~/mail, like 2010-mails, 2011-mails, mailing-list-x, mailing-list-y, and so on. How can I configure Dovecot to read them?. In /etc/dovecot/conf.d/10-mail.conf I have this: mail_location = mbox:~/Mail:INBOX=/var/mail/%u I'm using Ubuntu 11.10, and Dovecot 2.0.13.

[Dovecot] How to remove duplicate GUID messages from storage?
by Daniel Parthey 26 Apr '12

26 Apr '12

Hi, I tried to import messages like this: doveadm import -u username(a)example.org mdbox:/mail/dovecot/example.org/username/mail mbox:/root/mail.txt all This seemed to have imported the same messages in the mail storage, as they were already there. And now I have got a lot of duplicates. Then I deleted the mbox:/root/mail mail stuff from "mailboxes" folder and the storage remained, with duplicate GUIDs. The following command doveadm -v force-resync -u username(a)example.org INBOX outputs lots of messages like this one, with different GUID doveadm(username(a)example.org): Error: mdbox /mail/dovecot/example.org/username/mail/storage: Duplicate GUID 0b8a032d66a0924fb42c0000de5f8128 in m.55:45484041 and m.14:52173045 The messages at m.55:45484041 and m.14:52173045 have the same content, since they were seemingly imported from the mail store itself, they are in the storage twice now and require twice as much disk space as before. How can I manually remove these identical, duplicate messages from the storage to save space? Dovecot does not do it automatically. Kind regards, Daniel

[Dovecot] 2.1.5 problem with mail_location
by postmaster 25 Apr '12

25 Apr '12

I've been advised to set : mail_location = maildir:~/ as the home directory is found through a sql request. this has been working perfectly up to and including 2.1.4 from 2.1.5 however this setting gives cause to a problem : instead of looking in the mail home eg /var/mail/domain/user\@domain/ dovecot is looking for mail in /var/mail/domain/user\@domain/~ the '~' directory is created upon the first request for mail and all future mail transactions in dovecot is done relative to this folder. is this behavior a bug or a feature ??? -- Bjarne D Mathiesen København N ; Danmark ; Europa ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ denne besked er skrevet i et totalt M$-frit miljø MacOS X 10.7.3 Lion ; 2.8GHz Intel Core i7 ; 16GB 1067MHz DDR3

[Dovecot] dsync on large mailbox "fails"
by Jeff Kletsky 25 Apr '12

25 Apr '12

I've been trying to convert an existing set of mbox mail to maildir using dsync, but it seems to fail when it gets to the large boxes. $ dsync -Dv mirror maildir:~/Maildir Everything seems to work reasonably well until the first of the large boxes hits: dsync(jeff): Warning: Maildir /home/jeff/Maildir/.cron.2010-07-10: Synchronization took 1210 seconds (102289 new msgs, 0 flag change attempts, 0 expunge attempts) dsync(jeff): Warning: Transaction log file /home/jeff/Maildir/.cron.2010-07-10/dovecot.index.log was locked for 1210 seconds After this, the doveadm process goes from ~75% of the CPU core utilization to 100% and stays there, even overnight. I've also tried $ dsync -Dv backup maildir:~/Maildir with similar results. While I did see some threads on dsync speed, they seemed to be minutes for a few GB of data, not hours. There is plenty of space on the drive, and, from what I understand, there is not a file-count limit on FreeBSD's ufs (at least not one that I'm anywhere near) Any suggestions? Thanks!

[Dovecot] trash plugin bug?
by Cor Bosman 25 Apr '12

25 Apr '12

Hey all, has anyone ever tried turning on the trash plugin when the directory is already over quota? I see some messages being deleted, but it seems it just deletes enough to fit the new email, not enough to go below quota. Example: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591036 5242880) * QUOTA "Spam Quota" (STORAGE 21173 20480) I now move a 5K message into this folder, and I see: Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226337, msgid=<3YVKIIE4II6R0064BA7IM55C2Q4MD01VX12U1I(a)shedevils.com>, size=12984 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): expunge: box=Spam, uid=226338, msgid=<aab6bffa3ad83767d4a7bc571c31449c(a)bonus-news.com>, size=5623 Apr 23 22:26:43 lmtp1 dovecot: imap(cor): save: box=Spam, uid=227759, msgid=<20120423191509.F3B584A355B(a)signal.groundspeak.com>, size=2694 And now: . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam Quota" * QUOTA "User quota" (STORAGE 591016 5242880) * QUOTA "Spam Quota" (STORAGE 21158 20480) . OK Getquotaroot completed. This seems like a possible bug. For one, it shouldnt be allowed to actually save a message into that folder, but it does. The email does end up in the Spam folder even though the folder is over quota. And of course it doesnt clear up enough space to have the new email fit, it just deleted enough to match the 5K. Without the trash plugin quota is being properly enforced. Everything works fine if you start out below the quota limit btw. Regards, Cor ps: this is 2.1.4, but with the recent trash and quota patches applied.

[Dovecot] Dovecot Virtual Users with Users Domain Mapping
by Piotr Maier 24 Apr '12

24 Apr '12

I have successfully compiled, configured and ran Dovecot with virtual users feature. Here's part of my /etc/dovecot.conf configuration file: mail_location = maildir:~/Maildir auth default { mechanisms = plain login userdb passwd-file { args = /home/%d/etc/passwd } passdb passwd-file { args = /home/%d/etc/shadow } socket listen { master { path = /var/run/dovecot/auth-worker mode = 0600 } } } I faced one issue I can't resolve myself. Is there anyway to create users' domains mapping and provide username in mail_location? Example of usersdomains file: domain.com:user1 domain2.org:user3 Examples: 1. currently I have /home/domain.com/user/Maildir 2. I'd like to have /home/SYSTEM_USER/domain.com/user/Maildir Can I achieve this somehow?

[Dovecot] quota not being calculated
by Cor Bosman 23 Apr '12

23 Apr '12

It looks like my quota isnt being calculated properly after I started setting quota to a specific folder. The quota in that folder is always starting out at 0, and only new email is being added to the quota. If I remove the maildirsize file, and recalculate, it still starts at 0. Once email arrives in the folder, it gets added to maildirsize. This is with maildirquota, in perhaps a bit of an exotic config. The idea is to set a specific quota to Spam folder, using the trash plugin to keep it at a certain size. . getquotaroot "Spam" * QUOTAROOT "Spam" "User quota" "Spam quota" * QUOTA "User quota" (STORAGE 40848 1228800) * QUOTA "Spam quota" (STORAGE 0 20000) . OK Getquotaroot completed. Once 1 email gets added: .Spam# cat maildirsize 20480000S 0 0 2017 1 namespace { hidden = no ignore_on_failure = no inbox = yes list = yes location = maildir:%h:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/INBOX prefix = separator = / subscriptions = yes type = private } namespace spam { hidden = yes ignore_on_failure = no inbox = no list = yes location = maildir:%h/.Spam:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u/.Spam:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/.Spam prefix = Spam/ separator = / subscriptions = no type = private } plugin { quota = fs:User quota quota2 = maildir:Spam quota:ns=Spam/ quota2_rule = *:storage=20000K sieve = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/dovecot.sieve sieve_before = /etc/sieve/before sieve_dir = /var/spool/mail/dovecot-control/sieve/%1u/%2u/%u/scripts trash = /etc/dovecot/conf.d/dovecot-trash.conf.ext } (full config: http://pastebin.com/Mui4X7Zh)

[Dovecot] error when using dovecot-lda as non root (vmail) user

Hello, after finally having managed to setup up dovecot with virtual users and public folders I tried to get it connected to postfix. The problem is, that I can't get postix to deliver mail via dovecot-lda. After some testing it seems to come down to dovecot-lda behaving different when called as root then when called as user vmail.

[Dovecot] questions about SPECIAL-USE and virtual
by l.chelchowski＠eurocar.pl 23 Apr '12

23 Apr '12

Hi, I have some questions about Special-Use and virtual namespace: I want to create a virtual namespace with mailboxes: Sent, Unread, Flagged, All. 1. Is it enough to put in the config file: mailbox virtual/Sent { auto = subscribe special_use = \Sent } mailbox virtual/Unread { auto = subscribe special_use = \Unread #Is it correct? } mailbox virtual/Flagged { auto = subscribe special_use = \Flagged } mailbox virtual/All { auto = subscribe special_use = \All } and it would displays mail from every namespace I have subscribed (Shared, Public)? OR I have to make also dovecot-virtual files? 2. In dovecot-virtual file can I put for mailbox virtual/Sent something like: * \Sent 3. Is the http://wiki2.dovecot.org/Plugins/Virtual full documented, if not , where can I find it? 4. Is there a documentation for Special-Use? -- Łukasz

[Dovecot] Bug in HIGHESTMODSEQ when MODSEQ tracking is not enabled for version 2.0.18.
by Glenn Wurster 23 Apr '12

23 Apr '12

Greetings, I'm new to the list. I have encountered what I believe to be a bug in the return of HIGHESTMODSEQ when talking to a IMAP client. HIGHESTMODSEQ does not appear to be incrementing when a new message arrives. The exact steps I took are: 1) Create a new mail account 2) Send a mail to the account, check that you can receive the email. Send a second mail to the account. 3) perform a SELECT on the mailbox from a new session. PMLK4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest PMLK4 OK [READ-WRITE] Select completed. 4) Retrieve the mail. Then perform another SELECT on the mailbox from yet another session. LLEP4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 2 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest LLEP4 OK [READ-WRITE] Select completed. 5) Send another mail to the account, and check SELECT again. FKDA4 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 3 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1334074920] UIDs valid * OK [UIDNEXT 4] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest FKDA4 OK [READ-WRITE] Select completed. It appears as if HIGHESTMODSEQ is not being updated. I can get HIGHESTMODSEQ to start updating correctly if I send a "UID FETCH 1 MODSEQ" or similar command, which appears to enable MODSEQ tracking at the server (according to the comment around line 173 in file src/lib-index/mail-index-modseq.c), but until that command is sent, MODSEQ tracking is not enabled and hence HIGHESTMODSEQ is always going to return 1. According to RFC4551, the combination of HIGHESTMODSEQ and UIDVALIDITY should be sufficient to determine if the metadata associated with the mailbox has changed, but in this case looking at only those two parameters does not yield sufficient information about changes in the mailbox. The mail client I'm using relies on the combination of HIGHESTMODSEQ and UIDVALIDITY to determine if there are changes in the mailbox, and hence does not see new mail come in. It seems that Dovecot should not be returning HIGHESTMODSEQ in response to a command if MODSEQ tracking is not enabled, but I could be wrong. I've attached my configuration (it's Dovecot 2.0.18 running on Debian Stable). Let me know if you need more information.

[Dovecot] imapc / namespace question
by René Neumann 23 Apr '12

23 Apr '12

Hi, I've got two questions regarding imapc and namespaces: 1) Is there a way of stating, that I only want part of the hierarchy on the end of an imapc connection to be available here? My "problem": On the other end the layout is: INBOX.Shared.{some,nice,folders} If I mirror this into my dovecot hierarchy with prefix "Gemeinsam" I get the following folder structure: Gemeinsam.INBOX.Shared.{some,nice,folders} But I want to ignore the two top-most parts of the hierarchy, i.e. I want it to look: Gemeinsam.{some,nice,folders} Is this possible? I tried with 'location=imapc:INBOX.Shared.' but this did not change anything. 2) "Private" namespaces only make sense, if location contains something user-specific like "%u" or "~". Is this correct? If yes: Is there some other way to make something like an imapc connection only appear for one user, if there is nothing in the location or imapc_user to denote the user it belongs to and hence I cannot use "private"? The only way I see currently is to use "shared" and set up ACLs to forbid all users except one to access the namespace (which gets slightly ugly as I have to use global ACLs, as -- I think -- there is no way to store ACLs for an imapc storage). Thanks, René

This is just one dovecot IMAP client process moaning after another user client process pulled the rug out from under it by modifying the mailbox. I get a few dozen log entries of this sort per week with ~200 IMAP users without shared access. Unless your users actually complain about a problem, I think it's safe to ignore them.

[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

[Dovecot] Custom LDAP filter for doveadm-mailbox?
by Zhang Huangbin 19 Apr '12

19 Apr '12

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? Thanks. ---- Zhang Huangbin iRedMail: Open Source Mail Server Solution for Red Hat Enterprise Linux, CentOS, Scientific Linux, Debian, Ubuntu, Mint, Gentoo, openSUSE, FreeBSD: http://www.iredmail.org/

[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!

[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] 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

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

[Dovecot] trash plugin
by Cor Bosman 18 Apr '12

18 Apr '12

The trash plugin docs say: "Normally if a message can't be saved/copied because it would bring user over quota, the save/copy fails with "Quota exceeded" error. The trash plugin can be used to avoid such situations by making Dovecot automatically expunge oldest messages from configured mailboxes until the message can be saved" This leads me to believe that if a message cant be stored, the plugin would avoid returning a quota error, but instead delete/expunge messages until the original message can fit, and then complete the command. But I see something different, at least using the plugin in imap (havent tried it on lmtp). When I drag a message to a folder thats almost full, and the message doesnt fit, I get an actual quota error: 23 uid copy 454343 "Spam" 23 NO [OVERQUOTA] Quota exceeded (mailbox for user is full) After my client sees this error, I see the trash plugin creating space. But then it's too late right? The client already has a visible error. Am I just misunderstanding how the trash plugin is supposed to work? Dovecot 2.1.4, config is on a set of test servers: namespace { type = private separator = / inbox = yes } namespace { type = private separator = / inbox = no prefix = Spam/ location = maildir:/var/spool/mail/%1u/%1.1u/%u/.Spam:INDEX=/var/spool/mail/dovecot-control/indexes/%1u/%2u/%u/.Spam:CONTROL=/var/spool/mail/dovecot-control/%1u/%2u/%u/.Spam subscriptions = no list = yes hidden = yes } plugin { quota = maildir:Spam quota:ns=Spam/ quota_rule = *:storage=5000K } My goal is to create a FIFO spam folder that never returns a quota error, but instead just deletes the oldest emails as new spam comes in.

[Dovecot] Dovecot and Outlook Express "plaintext authentication not allowed..."
by D Chen 18 Apr '12

18 Apr '12

Server: Ubuntu 11.10 server with postfix (MTA), dovecot (MDA) Mail client: Outlook Express in Windows XP with IMAP on port 143, SMTP on port 25 When tried to set up a new Outlook Express mail acct, the following error encountered: Your IMAP server wishes to alert you to the following: plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. When asked "would you like to download folders from the mail server you added?" then got the following error: The server has rejected your login. Please verify that your user name and password are correct. I re-entered several time with the correct username and password, but still responded the same error. Any insights would be greatly appreciated. Here is the message from the /var/log/mail.log: Apr 17 01:54:17 server dovecot: imap-login: Disconnected (tried to use disabled plaintext auth): rip= 192.168.20.51, lip=192.168.20.100Apr 17 01:54:28 server dovecot: imap-login: Disconnected (tried to use disabled plaintext auth): rip= 192.168.20.51, lip=192.168.20.100 What might be wrong in my dovecot.conf file.
