[Dovecot] How to disable pop3 in version 2?
by Knute Johnson 24 Nov '11

24 Nov '11

I'm about to bring up a new mail server running Ubuntu 11.10 with Dovecot 2. I've been using 1.2 all along and there are a bunch more config files in 2. In 1.2 I just edited the protocols statement but I can't find one in version 2. Is there a way to disable pop3 or do I just firewall the ports? And a related question, I've been using imaps on port 993 but I hear that's not the best solution anymore, I should be using imap with STARTTLS? How do I disable imaps? Thanks, -- Knute Johnson

Re: [Dovecot] Seg fault in dovecot/auth 2.0.15

Sorry about the HTML. I removed the string "-O2" from the /auth Makefile and, for good measure, did make clean, make and make install for all of Dovecot. Still, it crashed when trying to log in via IMAP (webmail). Core dumped, here's the backtrace. [snip] Core was generated by `dovecot/auth -w'.

[Dovecot] 1.2.15 can't get zlib working
by Stan Hoeppner 24 Nov '11

24 Nov '11

Following these instructions: http://wiki.dovecot.org/Plugins/Zlib I enabled zlib and restarted Dovecot. I made a backup copy of a 68MB mbox file and moved it to a non mail directory. The mbox file is an existing TBird IMAP folder in my UNIX user mail directory. It is an archive of a defunct mailing list. It was a regular IMAP folder prior to attempting this. I was able to access all emails in the folder. It worked fine. I gzipped the original mbox file down to 14MB and removed the write flag with chmod. I launched TBird and received the following error in Activity Manager when accessing this IMAP folder: The current operation on '1-Spam-l' did not succeed. The mail server for account stan(a)hardwarefreak.com responded: Mailbox doesn't exist: 1-Spam-l I deleted the Dovecot index files and the TBird 1-Spam-l.msf file which didn't help. Curiously, there are no entries in either dovecot.err or dovecot.log, giving not even the slightest hint as to where I should troubleshoot. Kinda sucks when one follows instructions exactly, simple instructions at that, and it doesn't work, and generates zero log errors. A bit frustrating...

[Dovecot] v2.1.beta1 released
by Timo Sirainen 23 Nov '11

23 Nov '11

http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz.sig Here's the first beta release of Dovecot v2.1. This version has already been tested quite a lot, so I'm not expecting any major bugs. So please upgrade and see if you can find any problems. I'm optimistic about getting rc1 released this year and perhaps even v2.1.0. Since alpha2 there have been a lot of fixes, especially to imapc backend. There are probably also some small new features, but nothing huge. As a reminder, here's the largest changes since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] dovecot as an imap "client"
by David LEROUX 23 Nov '11

23 Nov '11

Hi, I need to get emails from one of my users imap account on a server which is not managed by us to his local imap mailbox. I'm almost sure that I've read some times that dovecot would be able to do that, kind of imap relay, but I can't find it again. I'm not sure to be very clear. Thanks, -- David

[Dovecot] [PATCH] SCRAM-SHA-1 authentication
by Florian Zeitz 23 Nov '11

23 Nov '11

Hy, over the last days I have implemented SCRAM-SHA-1 in Dovecot's 2.1 branch. It does not do SCRAM-SHA-1-PLUS, but should be extendable enough to introduce it later. There are some checks for the message format which (assuming the client acts correclty) are not strictly necessary during parsing. This is partially in the hope that it might aid client implementers, partially because it (IMHO) improves readability when checking against the RFC. Also errors found in this way could be sent to the client, this is however strictly OPTIONAL in the RFC, for now they are just logged. Some of the variable names are rather long. This is in order to have them match the terms introduced in the RFC, again I expect it to help readability (maybe my recent Objective-C programming showing though). I do feel somewhat insecure about my usage of some lib functions. Hopefully no API has been abused too much. I also note that there are a lot of fields in the scram_auth_request struct. I think they are all there for a reason, however feel free to prove me wrong. Attached is a hg export. It also includes a hmac-sha1 implementation, an adaption off of the hmac-md5 implementation already in Dovecot. I guess those should eventually be merged into a hash-independent hmac implementation, but I figured this would have to do for now. The implementation has been tested against GNU SASL and does appear to work fine. (The command line was `gsasl -m SCRAM-SHA-1 -a user -p pass --imap host` for those curious) Regards Florian "Florob" Zeitz

[Dovecot] Can't delete sub-folder
by pch0317 23 Nov '11

23 Nov '11

Hi list, I have problem with deleting sub-folder. I use thunderbird 8.0 as a client and dovecot 2.0.9 with imap protocol as a server. I use dovecot with tb-extra-mailbox-sep parameter. I use mbox mailboxes and thunderbird with *not checked* option 'server supports folders that contain sub-folders and messages' so when I create sub-folder I can choose between 'folders only' and 'messages only'. When I try to delete 'parent' folder which contain 'messages only' folder, error message appear: [ALREADYEXISTS] Mailbox has children, delete them first. Ok, so I delete 'message only' folder first and try to delete parent folder, but the same error appear: [ALREADYEXISTS] Mailbox has children, delete them first. When I list mailboxes from console I see inside 'parent' folder ".imap" folder. When I delete .imap folder from console and then delete parent folder from thunderbird, parent folder is deleted correctly. Which application create this ".imap" hidden folder and how solve this problem. Thanks

[Dovecot] Unique message IDs?
by Alexander Chekalin 23 Nov '11

23 Nov '11

Hello, I'm working with indexing my mail box. What I need is to have index in which mailing specified header string is located. I work with the messages via IMAP. I know that sounds like FTS can help me but no, I don't want to index whole message nor I want to patch FTS source to make it to index headers only. I need a way to identify message across my mail box. The idea is that I can move messages between IMAP folders and the index still should be able to identify it. What I want to know, will UID strings be unique across all my messages no matter which IMAP folder it belongs now to, or the UID can change if I move message? If I remove dovecot-uidlist from the folder will UIDs of messages in the folder be changed? What happened if I put a message to the given IMAP folder (and dovecot-uidlist will record UID for it), then shut down dovecot, and (given maildir storage model) move the message's file info another folder in the same mail box - after I start dovecot, will the UID for the message be the same or not? Thank you in advance, Alexander Chekalin

[Dovecot] dsync strange duplicate directories
by Frank 23 Nov '11

23 Nov '11

Hello, i'm testing whether dsync will help me in setting up a redundant master - master imap setup and experience this: 1. Master 1 dovecot is running, master 2 dovecot is down 2. I use rsync to create an exact copy of the master 1 maildir on master 2 3. I start up master 2 dovecot 4. I do a dsync on master 2: dsync -D -u test(a)example.com mirror ssh root@master1 dsync -D -u test(a)example.com Now what i see is this: Each mail directory is duplicated on master 1 and master 2 to a directory name with some MD5 hash value (as it seems) e.g. before dsync: ls -a /home/vmail/example.com/test/Maildir cur new .Drafts .Junk .Sent ... after dsync: ls -a /home/vmail/example.com/test/Maildir cur new .Drafts .Drafts_af61060f6f9fcb4efc0a00002691362e .Junk .Junk_b261060f6f9fcb4efc0a00002691362e .Sent .Sent_b261060f6f9fcb4efc0a00002691362e ... The new directories contain the same files as the original directories. What am i doing wrong? Thanks for the help Frank

[Dovecot] No duplicates on imap copy?
by Alexander Chekalin 22 Nov '11

22 Nov '11

Hello, when from my script I try to copy messages from one imap folder into another own (within the same imap mailbox). That works perfectly, but... If I copy the same message N times from one folder into another one, in the destination folder I see N copies of the same message, each with its own UID. I wonder if there any way to deduplicate folder content (so in the destination folder I'll get only one copy of each message)? I'd implement something like that myself in my script but I just don't know which part of the messages should I compare - probably md5 of headers? Thank you in advance! Yours, Alexander Chekalin

[Dovecot] Dovecot Log analysis

Hello, Before writing them myself, I'd like to figure out if some tools exist (anvil ? ...) and how to use them to extract from dovecot logs things like who is doing what and how hard or how fast in order to do some rate limiting. For instance, I'd like to be able to identify, slow or block users who . read or write to much / slice of time . login/logout too often / slice of time Note : I'm still using the 1.2.x branch.

21 Nov '11

We are currently experiencing performance issue with our Dovecot system which we believe is caused by excessive writes to the dovecot files. The confusing thing is that we are seeing more writes than reads on our Dovecot volume when you would assume that most of the IO should be reads from customers checking their mail. We're seeing reads vs. writes similar to the following: # iostat -d 5 -x Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util dm-4 0.00 0.00 485.80 865.80 3886.40 6926.40 8.00 28.69 19.63 0.70 94.00 drbd0 0.00 0.00 485.80 865.80 3886.40 6926.40 8.00 111.42 94.44 0.74 99.60 We can't figure out why we would be seeing twice as many writes as we are reads. Could this have something to do with the index files? Appreciate any assistance on this issue.

[Dovecot] Question about imaps
by jgiles＠cybermesa.com 21 Nov '11

21 Nov '11

Hi List! Had a questions about imap vs. imaps. I read the ssl article at http://wiki2.dovecot.org/SSL and from what I am reading, imaps is no longer needed as imap with initiate SSL/TLS on its own if STARTTLS is started and I have disable_plaintext_auth=yes and ssl=required settings. I do have SSL up and working, and can connect using imap (143) to my server without issue, but was not able to connect using imaps (993) using Kmail as my client. I Was getting a client error stating that the authentication failed using my password. However, there was nothing in the mail.err or mail.log file even when I enable debugging. If I specify imaps as my only protocol, then dovecot fails to even start without any error loging at all. As I stated, imap works just fine. So, is imaps deprecated as mentioned in the article and imaps no longer needed? I am running Dovecot 2.0.13 on an Ubuntu 11.10 64bit server. This server is simply an imap serer and not a MTA (No postfix or sendmail installed.) Thanks! Joe

[Dovecot] issues with 2.1b1 on OS X
by metro_domain_admin＠fastmail.fm 21 Nov '11

21 Nov '11

Two issues came up for me when building 2.1beta1 on OS X (10.5.8 on PPC). The first was already mentioned in an earlier thread by a BSD user (http://dovecot.org/list/dovecot/2011-September/061201.html) I just wanted to point out that the error is still occurring in spite of a new test for GNU ld in the configure script. I needed to remove "-no-undefined" specifically: #NOPLUGIN_LDFLAGS="-no-undefined" if test "$with_gnu_ld" = yes; then NOPLUGIN_LDFLAGS="$NOPLUGIN_LDFLAGS -Wl,--as-needed" fi More important, Dovecot aborts on launch with the following error: Nov 19 10:23:52 kerio2 dovecot[33553]: master: Fatal: kevent(EV_ADD, READ, 16) failed: Invalid argument I configured using the same args as I had used successfully on 2.0.15: --with-gssapi --with-ldap --with-sql --prefix=/opt/dovecot-2.X.X. I also tried an exact copy of my known-good config from 2.0.15, to no avail. Thanks, Tony

[Dovecot] Released Pigeonhole v0.2.5 for Dovecot v2.0.16
by Stephan Bosch 19 Nov '11

19 Nov '11

Hello Dovecot users, Before I move active development of Pigeonhole to Dovecot v2.1, I first release all the pending bug fixes and small improvements. Changelog v0.2.5: + Sieve vacation extension: made discard message for implicit delivery more verbose - The sieve-test tool: mixed up original and final envelope recipient in implementation of command line arguments. - Sieve vacation extension: resolved FIXME regarding the use of variables in the :handle argument. Variables are now handled correctly. - Sieve body extension: fixed handling of :content "message/rfc822". This now yields the headers of the embedded message as required by the specification. Handling of :content "multipart" remains to be fixed. - LDA Sieve plugin: fixed problem with recipient_delimiter configuration. Now it falls back to global recipient_delimiter setting if plugin/recipient_delimiter is not set. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.5.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.5.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] CCing outbound IMAP mail?
by Dave Stevens 18 Nov '11

18 Nov '11

For some users on my site I'd like to be able to CC a particular user on all outgoing IMAP mails. Incoming I can do but don't see how to do outgoing. Ideas?

[Dovecot] Mail_quota plugin and LDAP on Dovecot 1.2
by Victor 18 Nov '11

18 Nov '11

Hi, I'm new in this List, but I have 6 years using Dovecot on my debian from etch,lenny and now squeeze Package: dovecot-imapd Version: 1:1.2.15-4 Tags: squeeze -- System Information: Debian Release: 6.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/24 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages dovecot-imapd depends on: ii dovecot-common 1:1.2.15-4 secure mail server that supports m ii libc6 2.11.2-10 Embedded GNU C Library: Shared lib ii libldap-2.4-2 2.4.23-7 OpenLDAP libraries ii libssl0.9.8 0.9.8o-4 SSL shared libraries the quota_imap plugin not working when I use against MailquotaSize Attribute of LDAP users. this setup works perfectly on lenny and dovecot-imapd 1:1.0.15-2.3 but on squeeze dovecot-imad 1:1.2.15-7 doesn't work, the service is up, but The quota does not display. In logs nothing happens the configuration in dovecot.conf below protocol imap { mail_plugins = quota imap_quota } protocol lda { mail_plugins = quota } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } the configuration in dovecot-ldap.conf below uris = ldap://server-ldap.com.ve auth_bind = yes ldap_version = 3 base = dc=dominio,dc=com,dc=uk deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota=dirsize:storage user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(uid=%u)) This is the same configuration in the 6 last years. So, I would really appreciate if give me a hand which are more than 15000 Users who administered easily taking the quota in the LDAP attribute. and I want to keep the scheme.
