[Dovecot] (summarized) wishlist :-)
by Clemens Schrimpe 26 Nov '10

26 Nov '10

Hello All (and Timo in particular :-) -- While reading through some of the conversations on this list over the past two weeks or so, I always thought "how would <this> particular problem affect you and how would you address it in your environment?". This results in a few suggestions, or "thing to wish for", which I thought others may find useful, hence I'm posting this here. 1) the whole "post login scripting" is a mighty tool, yet it presently lacks a few more words in the documentation, i.e., the syntax of the corresponding config files isn't /entirely/ clear to me. Yes, I can replay the examples given, but I'm not fully sure, what happens when, etc. I'm perfectly willing, though, to contribute to that, by documenting findings in the Wiki2 (I'm just using 2.0.x, sorry). I'd appreciate a few more examples, so if anyone has a funny, working configuration, making good use of "post login scripting", I'd appreciate it, if you'd "show" them! :-) Anyway: A bit more "control" over PLS would be nice. For example, I'd like to have a script invoked every time a new "session" starts (new IMAP/POP3 connection from a unique ID), as many clients open multiple connections at once and usually I wouldn't want to see the second, third, nth connection - just the first. "Nice" would also a "post logout scripting" feature - again: Both for "all" connections, as well as just for the "last" one. Yes, this certainly requires a bit more discussion, I know - but I hope to trigger just that with this message! :-) 2) The "local x.x.x.x {" feature is very nice, yet it could use some "polishing", I guess. Inclusion of ports and wildcards for either addresses or ports, for instance. I'm imagining a syntax like this: local 1.2.3.4 { ... } like now to remain backward compatible local 1.2.3.4:* { ... } same result, just different new syntax -> don't care about port local 1.2.3.4:4711 { ... } add port restriction local *:4711 { ... } don't care for address, but match on port and -of course- (yes, I am really USING IPv6), the use of "[2001:xxxx:yyyy::zzzz]" instead of "1.2.3.4" in the examples show above. If one would like to become really funky, the optional "/xx" addition to specify a prefix-length would leave no more wishes open. (Well ... maybe the use of "names" derived from DNS instead of literal addresses, of course :-) [if this feature becomes clearer to me, I'd -again- be happy to help document it within the Wiki2] 3) The "iterate_query" in the SQL interface (I assume, there is something similar in the LDAP realm?) could be supplied with a few (optional, of course) "%x" variables, i.e., "%s" could deliver the "service" again, like with the other queries. This could tell the database engine, what the "show me all users" query is being used for ("quota", "expunge", ... basically all functions of doveadm, where you can supply a "-A" parameter). A "%{env:HOST}" could be used to tell the DB interface, which node of a multi-node installation is "asking". I.e., if you have your users distributed over multiple nodes, each one might want to perform "cleanups" only for their own users, saving a lot of bandwidth for unnecessary NFS traffic, etc. That's it - for now. Otherwise I'm pretty happy with dovecot, let me make that very clear here! :-) :-) :-) Clemens

[Dovecot] ioloop.c panic
by Brad Davidson 26 Nov '10

26 Nov '10

Timo, Just this morning I upgraded from 2.0.6 to 2.0.7 (hg changeset 66a523135836). A few hours later we had some power problems that caused the networking to drop out at one site. The directors on the surviving site all had a few imap-login processes crash with the following error: Nov 23 09:15:30 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:15:31 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:55:48 cc-director1 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) Nov 23 09:55:51 cc-director2 dovecot: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) I don't have core dumps enabled, so I can't provide any more information than that. I could enable cores, but I honestly would be hard-pressed to replicate the network cut-out anyway so I'm not optimistic that any cores for this message would ever be forthcoming.

[Dovecot] ldap passdb + mdbox
by Daniel L. Miller 26 Nov '10

26 Nov '10

I previously had a static userdb and an ldap passdb. Everything's been working fine, both 1.2 and 2.0 - but now I need to support the nightly mdbox purge operation. I added the iterate params to my ldap configuration, but (I'm guessing) that with a defined static userdb it won't work. How should I setup my ldap userdb? Do I use prefetch? Current config: passdb { driver = ldap args = /usr/local/etc/dovecot/dovecot-ldap.conf } userdb { driver = static args = uid=vmail gid=mail home=/var/mail/%d/%n mail=mdbox:/var/mail/%d/%n/mdbox allow_all_users=yes } dovecot-ldap.conf: ## dn credentials shouldn't be needed since using auth-bind - but here anyway dn = xxx,dc=amfeslan,dc=local dnpass = xxx ## auth_bind = yes auth_bind_userdn = uid=%n,ou=users,dc=amfeslan,dc=local ldap_version = 3 base = ou=Users, dc=amfeslan, dc=local user_attrs = dbox:%d/%n/Maildir=mail,%d/%n=home user_filter = (mail=%u) pass_attrs = mail=user,userPassword=password pass_filter = (&(objectClass=inetOrgPerson)(mail=%u)) iterate_attrs = mail=user iterate_filter = (&(objectClass=inetOrgPerson)(mail=*)) -- Daniel

Hello, is it possible to provide service auth on tcp-socket instead of unix-socket? I changed my conf and dovecot 2.0.5 is restarting but on telnet test it throws: dovecot: auth: Fatal: getsockname(12) failed: Socket operation on non-socket Want to separate smtp and imap to different servers but keep using dovecot auth for postfix-sasl. Whats to do? hmm, is postfix able to use non-unix socket for dovecot-sasl? Thanks, Hajo

[Dovecot] proxy (director) and destination ports
by Oliver Eales 26 Nov '10

26 Nov '10

Hello, i am delivering Mail from postfix via LMTP to dovecot. I am using the director also for LMTP. As long as i connect to the dovecot LMTP TCP socket from postfix everything is working. postfix main.cf: virtual_transport= lmtp:localhost:30025 But when i try to switch to the local socket postfix main.cf: virtual_transport = lmtp:unix:private/dovecot-lmtp The dovecot proxy tries to connect to the backend server port 0 which is obviously not working. The proxy always seems to connect to the same port on the backend as it was accessed itself. Nov 24 14:55:09 auth: Debug: master out: PASS 1 user=1000000000030 proxy Nov 24 14:55:09 lmtp(7330): Debug: auth input: user=1000000000030 proxy host=10.1.1.151 proxy_refresh=450 Nov 24 14:55:09 lmtp(7330): Error: lmtp client: connect(10.1.1.151, 0) failed: Connection refused Nov 24 14:55:11 director: Error: director(15.189.34.59:13459/out): connect() failed: Connection refused Is it possible to set the destination port (30025) of the backend server to the proxy ?

[Dovecot] Director and deliver
by Thomas Hummel 26 Nov '10

26 Nov '10

Hello Timo, Although I haven't tried neither director nor deliver, I'm planning to try both. I've been catching up with threads on this list talking about director but I'm not sure about how deliver would fit into a setup using director. Since deliver would touch indexes and dovecot-uidlist, wouldn't it need to be proxied as well through director ? Is that the case ? If not, how can we use deliver as LDA in a setup where n directors would proxy to m dovecot backends ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] maildir maintenance?
by Brian Kroth 26 Nov '10

26 Nov '10

Hi, I'm running version 1.2.15 (so no doveadm) with around 6000 maildir users, some of which are very large. For completeness, the details of the setup are as follows: - The maildirs are stored via NFS. - The indexes are on a volume local to the dovecot server. - Only one IMAP server currently. - A separate sendmail/procmail server delivers via NFS. I recently wrote the attached script (could probably be improved) meant in theory to be run as a nightly cron job to do the follow: 1) Remove old messages marked as deleted. (I didn't really like the expunge/trash plugins the last time I looked at them.) 2) Rebuild the indexes to account of those changes. (So that the users aren't delayed by dovecot rebuilding them.) 3) Rebuild FTS indexes. (Again to avoid delay.) 4) Rebuild the maildirsize file. (It seems to become slightly inaccurate over time.) To the devs, I'm wondering if this seems sane? To other users of dovecot, I'm wondering what, if any sort of maintenance operations you tend to do in your setups? Thanks, Brian

[Dovecot] Quota by max file size
by Antonio Perez-Aranda 26 Nov '10

26 Nov '10

Is It possible have a quota for max file size? Per example, If the client try to save a very big mail as draft, p.e. 100M, and the limit of Exim configuration is 20M, the mail is really saved in Maildir at sent or Draft but it can't be sent. I think maybe is easy to create a plugin, get the saved stream size and then if it is over quota max file size, abort save and notice to use about the limit, but at first I want to know that really daesn't similar exists.

[Dovecot] iPhone leaves imap process active
by Jim 26 Nov '10

26 Nov '10

A quick search of the archives didn't reveal a fix, so I thought I'd ask the list. I was running Dovecot 2.0.2, and noticed a lot of CPU being used up. I discovered a number of IMAP processes burning a lot of cycles, when no connections should have been active. I traced this to the iPhone leaving the IMAP connection apparently active. I just upgraded to Dovecot 2.0.7, and I'm still seeing connections left active, but haven't seen the high CPU usage yet, but I've only been running 2.0.7 for about 30 minutes. I tried adding kill_idle to the IMAP config, but that doesn't seem to have helped. Turning off the iPhone does kill the connection, so I know that the iPhone is really keeping the connection alive, but if I can find a way to keep these connections down, I'd really rather have that ability. Here's my config: wrights-Mac-mini:/Users/transmit wright$ doveconf -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.4.0 i386 hfs auth_mechanisms = plain login cram-md5 default_internal_user = _dovecot disable_plaintext_auth = no first_valid_gid = 27 first_valid_uid = 27 last_valid_gid = 27 last_valid_uid = 27 mail_gid = 27 mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = postfix mail_uid = 27 namespace { inbox = yes location = prefix = type = private } passdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { process_limit = 64 } service imap { idle_kill = 150 secs process_limit = 128 } service pop3-login { process_limit = 64 } service pop3 { process_limit = 128 } ssl = no userdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocol lda { postmaster_address = postmaster(a)example.com } wrights-Mac-mini:/Users/transmit wright$

[Dovecot] auth_username_chars - special chars
by Hajo Locke 25 Nov '10

Hello, i use dovecot 1.2.11 with auth by mysql. auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@üÜöÖäÄ for some reasons more special chars in username are needed. in fact the % char is meant. Is this recommend to use with mysql? should i expect some problems when using chars with special function within mysql? Config is now: auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb prefetch { } } password_query = SELECT `inbox` as `user`, `password`, `home` as userdb_home, `uid` AS userdb_uid, `gid` AS userdb_gid FROM `mail_users` WHERE `login` = '%u' AND `active`='Y' Thanks for your ideas, Hajo

[Dovecot] dovecot transport with postfix and recipient restrictions.
by Mauro 25 Nov '10

25 Nov '10

I'm using dovecot deliver with my postfix smtp. In postfix configuration I have: smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/maps/recipient_checks and in recipient_checks I have: mail(a)example.com REJECT. It doesn't work. Perhaps the recipient restriction has to be put in dovecot side? How can I do this.

[Dovecot] Automatic expire on post-login

25 Nov '10

I need to clear two folder from Maildir at login. Exatly, delete all mails older than 30 days on Trash and 1 day on spam folder. I'm using dovecot 2.0 and I think about use a post-login script calling doveadm -u $user expunge but post-login scripts in dovecot 2.0 are very complex Is there possible to get the environment vars like on dovecot 1.2 ? I think this action must be done by expire plugin, but it isn't the work method if as I understand after read wiki2.dovecot.org about expire plugin, It run only with a cronjob.

[Dovecot] doveadm purge output

24 Nov '10

Running "doveadm purge" with both -D and -v parms, and both -A and -u options, I don't see much in the way of output. doveadm -v purge -u username just returns with no output doveadm -v purge -A returns no output for most users - for my own mailbox it yields "20 / 21" -D returns the same, along with messages about skipping plugin modules. Is this normal? I'm thinking not - since after deleting messages in the client, emptying the trash, compacting from the client, and then performing a purge - I see no difference in mailbox files. -- Daniel

[Dovecot] two mailboxes - sieve?
by Egbert Jan van den Bussche 24 Nov '10

24 Nov '10

Hi helpful list! I have this user that has two different accounts om the mail server. One is a system account, the other is a virtual account (for what it is worth...). This user would like to have all his email to the virtual mail box (maildir format) automatically moved (or delivered) to the system mailbox (also maildir fornat). Both are on the same machine and use the same postfix/dovecot installation. Something tells me that I might need the sieve plugin for lda here since dovecot is the local delivery transport. I have no knowledge whatsoever about sieve or its scripting. What do I need to o apart from enabling the sieve plugin in dovecot.conf? Or is there another simple solution for this problem directly in Postfix or with fetchmail? A simple working example would be wonderful! TIA Egbert Jan (NL)

[Dovecot] gnus/dovecot open transactions panic
by Greg Troxel 24 Nov '10

24 Nov '10

I have been using dovecot with gnus for a long time. Recently, I started getting failures, and I think it's a dovecot problem triggered by gnus being more aggressive, but I'd like to hear opinions about whether I should pursue this as a gnus bug. The log shows: Oct 25 19:27:36 gdtserver dovecot: IMAP(gdt): Panic: Trying to close mailbox foo.bar with open transactions Oct 25 19:27:36 gdtserver dovecot: dovecot: child 26231 (imap) killed with signal 6 (core not dumped - set mail_drop_priv_before_exec=yes) and this seems to be triggered when dovecot is going GCC: to a local mailbox (not imap) when sending, but also semi-randomly. most of dovecot -n: (I'm sure that I'm not having auth problems and would rather not post that part): # 1.2.14: /usr/pkg/etc/dovecot.conf # OS: NetBSD 5.1_RC1 i386 protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/pkg/libexec/dovecot/imap-login login_processes_count: 4 login_max_processes_count: 16 max_mail_processes: 32 first_valid_uid: 128 mail_location: maildir:~/IMAP I have 162 mailboxes polled by gnus on this dovecot instance. I get the panic on various mailboxes and I can't see a pattern. I do get Checking new news... nnimap-send-command: SIGPIPE raised on process *nnimap*; closed it From gnus. I then look at the listed one in the panic, and *imap-log* From gnus. This just may be an artifact of pipelining, but the panic-list mbox has 30 more after it that were sent, as in: 19:35:43 506 EXAMINE "mbox.named-in-panic" (QRESYNC (1208908407 1)) [30 more lines] I'm guessing that this is a dovecot problem. I realize I should update to 1.2.15 :-) but I didn't see anything in the 1.2.15 release notes that looks like a match.

[Dovecot] Doveoct crashes: UID
by Peer Heinlein 23 Nov '10

We're running Dovecot 2.0.2 and sometimes a user creates several imap- prozesses, all of them hanging with the UID-command, using 100% of the CPU resources: root@mail:~# ps ax | grep UID 8005 ?

[Dovecot] Namespace help
by Joy 23 Nov '10

23 Nov '10

Dear All, I am currently using courier-imap which uses INBOX. namespace configuration now i am willing to use dovecot instead of courier-imap but without INBOX. namespace configuration means default namespace of dovecot which helps me to sort out no of mail client issues as well. I know that i can change the default namespace configuation of dovecot to work with courier-imap namespace but not willing to do that so suggest me something which can help me doing the same. Is it possible using postlogin script or something else ? Thanks Regards Piyush Joshi

[Dovecot] multiple IMAP ports, each announcing different capabilities
by Clemens Schrimpe 23 Nov '10

23 Nov '10

Hello - is it syntacticly possible to define different "imap_capability" settings per each inet-listener? I might have to provide a service through a caching proxy sitting in front of dovecot, which might involve restrictions re: the announced imap capabilities. Any hint is highly appreciated! Greetings, Clemens

[Dovecot] "list" ACL privilege ignored for LSUB command?
by Willie Gillespie 22 Nov '10

22 Nov '10

Hello, I am new to this list, so feel free to correct me if I do something wrong. I don't have a problem, just a question. The RFC which covers IMAP ACLs [1] states that one of the standard rights is: l - lookup (mailbox is visible to LIST/LSUB commands, SUBSCRIBE mailbox) If I have a shared or public namespace and have a mailbox for which I do not have lookup rights, Dovecot seems to do great with the LIST commands at not showing it to me. Two things I noticed though: SUBSCRIBE-ing to the mailbox is still successful LSUB will list mailboxes which I do not have lookup rights to I imagine the first issue is easy enough to correct since it's just another check before actually subscribing. The second issue seems a little more difficult in my mind since Dovecot seems to just dump the subscription files to the client without checking whether the mailbox is allowed or not. I imagine a similar issue popped up with the LIST command and that's why the dovecot-acl-list files exist. Anyway, am I right in my observations, or am I completely overlooking something obvious? Thanks! Willie [1] http://tools.ietf.org/html/rfc4314#section-2.1 Dovecot's wiki also indicates support for this in http://wiki1.dovecot.org/ACL#ACL_files I'm using version 1.2.9 with the acl and imap_acl mail_plugins in case that matters.

[Dovecot] Soft Quota for moving messages
by Tim Traver 22 Nov '10

22 Nov '10

Hi all, ok, I have an account that is over quota, but they are unable to move things to the trash, because the system is giving an error because of course it is over quota. Is there a quota setting that will let them move things to the trash without error? this of course would be so they could decrease their disk usage and become under quota again... Thanks, Tim.

[Dovecot] Workaround for evolution?
by Axel Thimm 22 Nov '10

Hi, evolution has a bug when it comes to closing and IDLE' connection: https://bugzilla.gnome.org/show_bug.cgi?id=628515 evolution does not send a DONE command, and dovecot properly answers with an error. evolution ignores this and seems to wait on another response. Timo, do you think there could be a setting for tolerating missing DONEs? Thanks! -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] What is that error all about: "Timeout leak: 0x4bd230"
by Christian Rohmann 22 Nov '10

22 Nov '10

Hey dovecot-users, we are running dovecot 1.2.15 and are seeing some odd errors in our logfiles: --- dovecot.log --- 2010-11-22 12:34:56 imapserver local2.warning dovecot dovecot: IMAP(username(a)domain.tld): Timeout leak: 0x4bd230 --- /dovecot.log --- Those errors only appear if connections are done using IMAP (via Horde's IMP Webmail). With POP3 we don't see any of those errors. We actually don't see anything in general being broken or wrong (no errors on the webmail machines, no user complaints), but these errors are constantly being logged. Where would one start to look for the cause? Thanks for your help, Regards Christian

[Dovecot] Confused about Maildir
by Glen Lee Edwards 22 Nov '10

22 Nov '10

I'm trying to configure Dovecot 2.0.7. In the Dovecot Wiki for Maildirs it says that Maildirs are almost always located in ~/Maildir. I'm a Linux end user, not a programmer, so I may be wrong in this; but isn't the notation "~/" used for system users only to reference their home page; /home/<user>? If that's the case, then does that mean that Maildirs can only be used with system users and not with vmail accounts? Glen

[Dovecot] dsync mbox->mdbox II: highest_modseq changed
by Axel Thimm 19 Nov '10

19 Nov '10

Hi again, after replacing CRLF in 4 mboxes dsync was able to sync all of the 30+GB mailstore to mdbox. Now the (repeated) calling of dsync yields info messages of the kind dsync(athimm): Info: old/speicher: highest_modseq changed: 1 != 10 dsync(athimm): Info: root/root-heretic: highest_modseq changed: 1 != 10 dsync(athimm): Info: lists/ccrma.stanford.edu/planetccrma: highest_modseq changed: 11 != 14 I actually have 987 such messages for a total of 1115 mboxes. I checked a couple of them to see whether this is a CRLF issue and found no CRLF, so it's probably something different. As long as the mboxes were still being delivered to or read from I thought it was normal, but I'd like to see a silent dsync which would give me more confidence in the migration process. So I kept from delivering to the mbox store as well as reading from it and performed multiple dsyncs. The output of dsync became stable, e.g. the "highest_modseq changed" messages were exactly the same. Before nuking all indexes from the mbox storage and the mdbox itself and then repeating the whole process (which does take a long time), I wanted to know whether I should debug something. Thanks! -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] Dovecot and user's quota
by oriol llistes 18 Nov '10

18 Nov '10

Hi, We are planning to use Dovecot-2.0.5 (Maildir format) as IMAP server. Currently, we are using Postfix+UW-Imap (mbox format) with the following configuration: - Postfix: Sends new messages to /var/mail/user - UW-IMAP: Reads mails from /var/mail/user and moves them to ~/nsmail/mbox Using that configuration, when a user overtakes his HOME’s quota, the MTA is still able to send new messages to the user, although he cannot read it until he frees HOME space. Can we configure Dovecot to work in the same way? I mean… 1)Postfix must use /var/mail partition for new mails. 2)Dovecot must move these mails to user’s HOME. 3)User’s HOME must be in Maildir format. If that is not possible, how can we achieve an equivalent solution? Thanks in advance. Oriol.

[Dovecot] dovecot with Active Directory problem
by marie ot 18 Nov '10

18 Nov '10

Hello, I am using dovecot-2.0.6 with NetBSD amd64. Active Directory is used as an authentication server. (Windows Server 2008 R2) However, the message of "Operations error" was displayed first and it did not move. It solved it by understanding that this is because the authority of the user who used it for bind was insufficient, and adding to "Account Operators" group. # Though it is not the best. The error "Error: re_encode_request new request is" occurs, and it doesn't operate still as follows. Postfix operates though connects with LDAP. The following are samples. ------------------------ # Active Directory Server settings domain = example.com server_host = ldap://xxx.xxx.xxx.xxx:389 search_base = dc=example, dc=com version = 3 timeout = 30 # Active Directory Searcher settings bind = yes bind_dn = cn=Mail Administrator, cn=Users, dc=example, dc=com bind_pw = ********* # Filter Query query_filter = (&(&(objectCategory=person)(|(mail=%s)(userPrincipalName=%s)))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = userPrincipalName result_filter = %s/ chase_referrals = no ------------------------ The packet was done with wireshark by using this definition and a capture doing and a similar test were done to dovecot. It is a setting of dovecot. ------------------------ hosts = xxx.xxx.xxx.xxx:389 dn = cn=Mail Administrator, cn=Users, dc=example, dc=com dnpass = ********* auth_bind = no ldap_version = 3 base = dc=example, dc=com user_attrs = unixHomeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_attrs = userPrincipalName=user,unixUserPassword=password pass_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) iterate_attrs = userPrincipalName=user iterate_filter = (&(objectCategory=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) default_pass_scheme = MD5 ------------------------ # Schema of LDAP is matched to Windows Services for UNIX, # and the password is made a hush with MD5. Both dovecot and postfix the first "bindRequest" was quite the same demand and the results. Next, dovecot demanded query of "userPrincipalName" and "unixUserPassword". It seems to be ok for the result. # This fails if it doesn't add to "Account Operators" group. However, "name" and "simple" were issued by the blank (anonymously?) as for the following next demand (bindRequest). In addition, query of "userPrincipalName" and "unixUserPassword" is issued to "cn=Configuration, dc=example, dc=com" afterwards. And, "Operations Error" is returned because of this. Error description in LDAP packet: ------------------------ errorMessage: 000004DC: LdapErr: DSID-0C0906DC, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db0 ------------------------ Because LDAP is unprofessional, it has not understood though the source code was seen. Do you serve as a reference? Thanks powerful codes.

[Dovecot] Multiple MYSQL hosts as passdb backend
by moody_cz 18 Nov '10

18 Nov '10

Hello, I use mysql as passdb backend for my dovecot 2.0.6 installation. I have 2 mysql 5.0.77 servers with master/slave replication enabled. My goal is to ensure dovecot's ability to provide its services even when one of the mysql hosts are unavailable. Here is my passdb backend conf: passdb { driver = sql args = /etc/dovecot/mysql.conf } and mysql.conf: default_pass_scheme = PLAIN driver = mysql connect = host=10.0.0.3 host=10.0.0.4 dbname=some_database user=some_user password=some_password password_query = some_query Everything works fine as long as 10.0.0.3 is up and running. However, when I shutdown mysql server on 10.0.0.3, dovecot won't even try the other host 10.0.0.4 as it is told to do in the conf. My dovecot verbose log says: Nov 16 14:29:24 auth: Error: mysql: Query failed, retrying: MySQL server has gone away Nov 16 14:29:24 auth: Error: mysql: Connect failed to 10.0.0.3 (some_database): Can't connect to MySQL server on '10.0.0.3' (111) - waiting for 1 seconds before retry Nov 16 14:30:28 auth-worker: Error: mysql: Query timed out (no free connections for 64 secs): some_sql_query Nov 16 14:30:28 auth-worker: Error: sql(mail_user,127.0.0.1): Password query failed: Not connected to database Nov 16 14:30:28 auth: Error: auth worker: Aborted request: Lookup timed out Nov 16 14:30:28 auth: Error: mysql: Connect failed to 10.0.0.3 (some_database): Can't connect to MySQL server on '10.0.0.3' (111) - waiting for 1 seconds before retry Nov 16 14:31:33 pop3-login: Info: Disconnected (auth failed, 1 attempts): user=<mail_user>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured What am I doing wrong?

[Dovecot] add basic systemd support to dovecot
by Christophe Fergeau 17 Nov '10

17 Nov '10

Hi all, In the last days, I've been trying to add support for systemd[1] socket activation to dovecot. The basic idea is that systemd takes care of opening the sockets needed by dovecot to communicate with external processes, and when a connection happens on one of these sockets, systemd spawns dovecot, and then dovecot uses these sockets instead of creating its own sockets. The main reason why I hacked on this was that I wanted to get on-demand startup of dovecot on my home box. WIth the patch attached to this email, I'm now able to do that. The patch includes a dovecot.socket file which should be seen as a sample file, however I'm not sure what is the best way to handle this file (systemd uses it to know which sockets dovecot needs). What I wanted to ask the list for now is if such a patch is wanted, and to get feedback on how things are done in it, and what should be improved in it. [2] and [3] might be useful reading while looking at the patch. Thanks in advance for the feedback!

[Dovecot] Ongoing performance issues with 2.0.x
by Ralf Hildebrandt 17 Nov '10

17 Nov '10

Due to the ongoing performance issues with 2.0.x I switched back to 1.2.15 yesterday evening, with no changes to the machine or my users. (I migrated from 1.2.15 to 2.0.x by converting the existing config) Today, we have MUCH LESS load, with the same number of logins/min. I cannot say what exactly causes this immense increase in load, but one observation is that the time spent in system() has now dropped (user and iowait have stayed contant) to a third of the values I was seeing with 2.0.x. This evening I'll post some graphs showing two comparable 24 hour ranges. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] child 23925 killed with signal 6
by Jan Behrend 17 Nov '10

17 Nov '10

Dearest list, just now I migrated a pine user to dovecot. Nothing special so far, but then I saw this in my syslog and the user reported, that he got this error message: MAIL FOLDER "INBOX" CLOSED DUE TO ACCESS ERROR Obviously this problem is related to his local filter rules: If commented out everything works like a charm.

[Dovecot] local users and virtual users
by Egbert Jan van den Bussche 17 Nov '10

17 Nov '10

Hi list, I'm facing this problem: I have a e few local (system) users and a bunch of virtual users (in MySQL). To make it easy for the big group, I've set a default domain which is not the domain of the server (which is just the servername). So the big group logs in with there short name without @<domain>. BUT the few system users (in passwd) cannot login to pop or imap because they get the non-local domain attached and cannot be found in the mysql db but they cannot be found in passdb either with their long name. The same applies when system users give their longname with the local domain which IS the localname of the server. This name is not in mysql nor passdb either. Is there a way to find local users in passdb when the come in with a long name? Do I need another passwd like file (i hope not...) Recap: local Domain is :mail-dev.hobby.nl default domain added bij dovecot is kader.hcc.nl kader users are found in mysql regardless if they give @kader.hcc.nl or not (then it is added) system user are never found since longname is not in mysql nor in passdb. dovecot -n: root@mail-dev:/etc/dovecot# dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-25-server x86_64 Ubuntu 10.04.1 LTS log_path: /var/log/dovecot/error.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s managesieve listen: *, [::] ssl_cert_file: /etc/ssl/certs/ssl-mail.pem ssl_key_file: /etc/ssl/private/ssl-mail.key ssl_cipher_list: ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 3 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes first_valid_uid: 200 mail_privileged_group: vmail mail_location: maildir:~/Maildir mail_debug: yes mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): convert autocreate mail_plugins(imap): convert autocreate mail_plugins(pop3): convert autocreate mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): lda: postmaster_address: postmaster deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login realms: kader.hcc.nl hobby.nl default_realm: kader.hcc.nl cache_size: 1024 verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: failure_show_msg=yes cache_key=%u dovecot passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd args: mail=maildir:~/Maildir userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: convert_mail: mbox:/disk/mail/convert/%n autocreate: Trash autocreate2: Sent autocreate3: Drafts autocreate4: Spam autosubscribe: Trash autosubscribe2: Sent autosubscribe3: Drafts autosubscribe4: Spam Pse help.

[Dovecot] Dovecot + vpopmail + shared folders
by qmail＠top-consulting.net 17 Nov '10

17 Nov '10

I'm using dovecot 1.2.14 with vpopmail. I've enabled shared folders and the default setup was not working. The default setup being this line: location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u Going through the Archives I saw a message from Timo that said to apply a patch and use this line instead: location = maildir:/usr/home/vpopmail/domains/%d/%%n/Maildir:INDEX=~/Maildir/shared/%%u It seems like the patch is already existing in version 1.2.14 and that line works well for shared folders for domains directly under /usr/home/vpopmail/domains. However, with vpopmail after a certain number of domains, it starts putting them in /usr/home/vpopmail/domains/A, ..domains/B, etc. Shared folders do not work for those domains since my location line is forcing it to look directly in /usr/home/vpopmail/domains/xyz.com instead of /usr/home/vpopmail/domains/A/xyz.com Any workaround this ? How come we can't use %h or ~/ directly ?

German law limits the use of profiles like these quite strictly; in general an employer has no business to log all these actions generally. This does not mean it can be helpful for diagnosing problems, but I would not recommend to do so as a general procedure. On the other hands, it is a de-facto requirement today that you can trace every communiction that has entered the company. The only place where you can do this without potentiall missing some messages is the MTA. This is why all the archival tools want to couple to the MTA... JC

Hello This is a bit off Dovecot but ... I'm searching some software to mirror mailboxes and IMAP forlders from the mailhub to another (clone) computer. Actually I use rsync daily but I wonder if it exists some software that are real time mirroring capable ? I'm using Dovecot 1.2.14 and Postfix with MBOX format. Thanks

[Dovecot] Mail history function?
by Oliver Berse 17 Nov '10

17 Nov '10

I'm a newbie at Dovecot. For a company groupware I need a kind of a history function for mails to see which user sent which mail to whom / got which mail from whom. So I have to get the message ID of in- and outgoing mails (and write related data to a mysql database). My first idea was to monitor the log file with a daemon and search for strings like "deliver(x(a)y.z): 2010-11-15 17:34:56 Info: msgid=<AANLkTikoRgUiEg2KgUW2gLmULD4TX-bPst4yhUbuHoEH(a)a.b>". I'm not sure if this is the right approach. Does anyone know a better solution with Dovecot? thanks, Oliver

[Dovecot] Single-instance storage Thank You
by Daniel L. Miller 17 Nov '10

17 Nov '10

Timo, On following my previous thread that went somewhat off-topic, I noticed - or rather failed to notice - any response from you. This leaves me to draw one of the following conclusions: 1. You didn't see it. 2. You ignored it. 3. You saw it, took offense, and disregarded it. 4. You saw it, accepted the compliment for what it was - and didn't bother to respond. On the chance any of options 1-3 apply - please allow me to state as clearly as possible: your creation, that of Dovecot in general, and single-instance mdbox storage in particular, have significantly contributed to my own ease of system administration - and I offer my sincere thanks and admiration. -- Daniel

[Dovecot] Help - custom vpopmail
by Rick Romero 16 Nov '10

16 Nov '10

Hi, First, I'm not sure if dovecot should alter this, but it seems vpopmail writes the IP into the 'remote_ip' field instead of the auth type. Dovecot still writes the auth type. I want both. So I modified my vpopmail install to write an additional field into the lastauth table. My custom vpopmail writes the remote IP into remote_ip, and the auth type into a 'type' field. I tested with qmail's POP3 daemon to verify vchkpw would fill the table correcly. But I'm not sure how to get dovecot to do it: I know this is close, but there is something not right in src/auth/userdb-vpopmail.c line 99. vset_lastauth(vpop_user, vpop_domain, &auth_request->remote_ip, t_strdup_noconst(auth_request->service)); I'm, by far, NOT a C programmer - Feel free to laugh at my code publicly :) Thanks, Rick

Now that it is enforced, you might notice that the default limit is too low and you need to increase it. Dovecot logs a warning when this happens. * mail-log plugin: Log mailbox name as virtual name rather than physical name (e.g. namespace prefix is included in the name) + doveadm dump: Added imapzlib type to uncompress IMAP's COMPRESS DEFLATE I/O traffic (e.g. from rawlog). - IMAP: Fixed LIST-STATUS when listing subscriptions with subscriptions=no namespaces. - IMAP: Fixed SELECT QRESYNC not to crash on mailbox close if a lot of changes were being sent. - quota: Don't count virtual mailboxes in quota - doveadm expunge didn't always actually do the physical expunging - Fixed some index reading optimizations introduced by v2.0.5. - LMTP proxying fixes

[Dovecot] dsync mbox->mdbox: Unexpectedly lost From-line and other issues from a big conversion.
by Axel Thimm 16 Nov '10

16 Nov '10

Hi, I'm trying to convert a 33GB mail store from mbox to compressed mdbox (largest mbox is 2.7GB). The source store is live, e.g. there are mails delivered into it and mails are being read. Actually it is my own mail. :) Although my test runs were very successful I have run into trouble with the first run on the whole store. After fighting a bit around with errors like Error: Trying to open a non-listed mailbox with guid=f59c5b31b8f3df4c70180000e7dd553b I did several reruns in case these errors would be fixed on the next iteration, but my mdbox storage wasn't growing anymore. I decided to restart after removing all old index files from the source store in case I had some corruption somewhere. Since on mbox/maildir index files are completely recreatable this would just slow down thing at the worst. Indeed many of the errors went away, and I managed to convert about 10-20%, but then I hit another array of errors that would persist even after restarting: > $ grep -v Info: dsync2.log.old* > dsync2.log.old1:dsync(user): Error: Next message unexpectedly lost from mbox file /home/user/mail/lists/mplayerhq.hu/ffmpeg-devel at 58706201 (cached) > dsync2.log.old1:dsync(user): Error: read(msg input) failed: Invalid argument > dsync2.log.old1:dsync(user): Error: Next message unexpectedly lost from mbox file /home/user/mail/lists/gnupg.org/gnupg-users at 6507197 (cached) > dsync2.log.old1:dsync(user): Error: Unexpectedly lost From-line from mbox file /home/user/mail/lists/gnupg.org/gnupg-users at 6486645 > dsync2.log.old2:dsync(user): Error: mdbox /home/user/mdbox/mailboxes/lists/mplayerhq.hu/ffmpeg-devel/dbox-Mails: map uid lost for uid 26483 > dsync2.log.old2:dsync(user): Error: msg guid lookup failed: Internal error occurred.

I'd like to spot them and correct them, so I tried let's convert to maildir first, which I can debug more easily. Unfortunatly the conversion speed to maildir is about 25 times slower than converting to mdbox (wow!), and it would take almost 5 days to convert to maildir. This is no sane timeframe for debugging, so I'd rather try different tactics with mdbox. One thing I'm going to try is to do an offline conversion of a snapshot of the store. Anyway I wanted to document the issues I saw in case it is something that is a bug in dovecot. -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] POP users complaining about multiple copies of mail
by H. Wade Minter 16 Nov '10

16 Nov '10

Hello, We just switched from UW to Dovecot for our mail server. The transition went smoothly, except we have some users complaining about their email clients re-downloading mail or getting multiple copies of emails. When we go into their accounts, we only see one copy of the email, so I'm assuming there's something odd in the communication between their client and us that's causing the mail to get downloaded repeatedly. The clients that we've heard about are Outlook and one called "Goldmine". Has anyone run across this before? Scanning the archives didn't show me anything. This is Dovecot 1.2.12-1ubuntu8 on Ubuntu 10.10. Here's my config: # 1.2.12: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.4-rscloud x86_64 Ubuntu 10.10 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s managesieve ssl_ca_file: /etc/ssl/certs/ca.pem ssl_cert_file: /etc/ssl/certs/wildcard.skiltech.com.pem ssl_key_file: /etc/ssl/private/wildcard.skiltech.com.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_enable_last(default): no pop3_enable_last(imap): no pop3_enable_last(pop3): yes pop3_enable_last(managesieve): no pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): lda: postmaster_address: postmaster mail_plugins: sieve quota_full_tempfail: yes deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve

[Dovecot] Trying to building a customized auth plugin
by Antonio Perez-Aranda 16 Nov '10

16 Nov '10

I'm on dovecot 2.0.7 and I trying to building a customized auth plugin. I take passdb-passwd-file.c and userdb-passwd-file.c to try to build with a simple gcc comand out of dovecot environment as in example: export DOVECOT=/path/to/untar/dovecot-2.0.7 gcc -fPIC -shared -g -Wall -I$DOVECOT \ -I$DOVECOT/src/lib \ -I$DOVECOT/src/lib-auth \ -I$DOVECOT/src/lib-sql \ -I$DOVECOT/src/lib-settings \ -I$DOVECOT/src/lib-ntlm \ -I$DOVECOT/src/lib-master \ -I$DOVECOT/src/auth \ passdb-passwd-file.c -o passdb-passwd-file.o With this, I get errors relate with uoff_t Is possible to build this plugin by this way? Another way is patching against one plugin on dovecot RPM, but I prefer this on a separated RPM.

[Dovecot] Single-instance storage is bad for you!
by Daniel L. Miller 16 Nov '10

16 Nov '10

This single-instance storage is going to encourage bad habits! I just found myself preparing an e-mail that needs to be sent to multiple recipients - including several within my own organization - yet it's not necessary for everyone (in-house) to get the large attachment. As I was getting ready to split the message into two parts for distribution I remembered - I can just send it to EVERYBODY in-house and it only occupies a single instance - which it would anyway just being in my "sent" folder! Blasting away... You're quite the enabler, Timo! Now any mail admin who tries to lecture users on only sending attachments to those in-house personnel who really need it, because otherwise it's wasteful of precious server storage space, is going to hear the response, "Dude - don't stress out so much - just setup Dovecot with SIS!". Thanks again! -- Daniel

[Dovecot] service_count=0 for imap and pop3
by Mark Moseley 16 Nov '10

16 Nov '10

This is copy-pasted from Timo's comment in the "Todays Performance Data for 2.0.x" thread, but I didn't want to hijack that thread. In it, Timo says: <snip> service imap { service_count = 0 } (i.e. reuse imap processes) reduced the system CPU usage to almost nothing. But if you use different UIDs for different users you can't do that. </snip> Is that safe to do in imap and/or pop3? Or at least no more insecure than using service_count=0 for imap-login and pop3-login? Since I saw that comment I've been googling around and grepping the wiki but I can only find instances of using it with "service imap-login", not "service imap" or "service pop3". The mention in Timo's comment that it reduces the CPU usage by a lot got my attention, esp for pop3. We're already using service_count=0 for pop3-login and imap-login.

[Dovecot] Local node indexes in a cluster backend with GFS2
by Aliet Santiesteban Sifontes 15 Nov '10

15 Nov '10

Hi, all this days I'm testing a dovecot setup using lvs, director and a cluster email backend with two nodes using rhel5 and gfs2. In the two nodes of the email backend I configured mail location this way: mail_location = sdbox:/var/vmail/%d/%3n/%n/sdbox:INDEX=/var/indexes/%d/%3n/%n /var/vmail is shared clustered filesystem with GFS2 shared by node1 and node2 /var/indexes is a local filesystem at the node, so each node has his own /var/indexes stuff on ext3 and raid1 for improving performance, I mean each node a different /var/indexes of its own. Now, if the director was using node2 for the email for user1 and I removed node2 now all the connections for that user are redirected to node1, that node has its local /var/indexes, when this ocurr I can not see the emails that in fact are in the mailboxes, I guess should be indexes not current with the user mails. Is supposed indexes to be rebuilt automatically when the node switches?? Or I have to configure the indexes in the shared storage so the two node update the information concurrently? I will appreciate your help... best regards

[Dovecot] Is Dovecot Director stable for production??
by Aliet Santiesteban Sifontes 14 Nov '10

14 Nov '10

Today I will try Dovecot Director for a setup using a Cluster Backend with GFS2 on rhel5, my question is if is Director stable for use in production for large sites, I know is mainly designed for NFS but I believe it will do the job also for a cluster filesystem like GFS2 and should solve the mail persistence problem with a node and locking issues. I plan to add a layer behind a load balancer to do the stuff, I will appreciate if you guys can point me to best practices in configuring the director, or how the thing works since is new for me, I have seen the example conf but I don't have clarity in some of the concepts and the wiki is empty. I use 2.0.6, thank's for a great job with dovecot. best regards, Aliet

[Dovecot] squirrelmail inbox empty
by Paul Cartwright 13 Nov '10

13 Nov '10

I am running Dovecot + Postfix +Squirrelmail on Debian Lenny.Fetchmail pulls the mail, dovecot spreads it around. I had squirrelmail setup & I tested it from within my router ( internal LAN). yesterday I had to go babysit my grand daughter, and I setup port forward for IMAP port 143, and I can use squirrelmail through firefox on my laptop. All the other folders have all the mail from the time I left til now. Yesterday I was reading inbpox mail, deleted a few junks, etc, and suspended my laptop. When I came back my inbox was empty, and I've never seen any more messages in it. I know I should have LOTS of older+new messages that don't get filtered. Unfortunately ssh doesn't seem to work from this linux side, it does from the windos side ( ssh keys?), so I can't get in to look at the logs.. I already removed ( I think ) all the inbox index files... & restarted, but no joy. I am not sure if it is getting filtered from the ibox, or if I just can't see it. I am not familiar with how squirrelmail works with local IMAP folders, so I am unsure where to look or what logs to browse. I will be home later today. suggestions clues or otherwise?? -- Paul Cartwright

12 Nov '10

Hello , Went to /etc/dovecot/dovecot.conf, hunted down "ssl_listen =" which I had set it up to "ssl_listen = required" and commented it out. Tried "service dovecot start" and it started. The USD2,000,000 question being : what does this do (I know , I know, I cannot remember, I documented all this for v1.2.14) and will I need it in the future ?

[Dovecot] Occasional fchown errors?
by Knute Johnson 12 Nov '10

12 Nov '10

Hi: I get the occasional error below. Is there something I don't have configured correctly? Or should I just ignore this? It is not always this file, sometimes it is the cache.lock file or the log.newlock file. I have a mail client running on my computer and my phone at the same time, could that have something to do with it? Nov 10 08:32:59 rabbitbrush dovecot: IMAP(bob): fchown(/home/bob/mail/.imap/INBOX/dovecot.index.tmp, -1, 8(mail)) failed: Operation not permitted (egid=1000(bob), group based on /var/mail/bob) From dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-25-generic i686 Ubuntu 10.04.1 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps ssl_cert_file: /etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key_file: /etc/ssl/private/ssl-cert-snakeoil.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks: fcntl dotlock auth default: passdb: driver: pam userdb: driver: passwd Thanks very much, -- Knute Johnson

[Dovecot] questions of how to connect to pop3s
by Scott Berry 12 Nov '10

12 Nov '10

Hello there, I am new to Dovecot and I am using version1.2.12. I have included the dovecot -n output: root@ubuntuSnoopBear:/home/scott# dovecot -n \# 1.2.12: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35-22-generic-pae i686 Ubuntu 10.10 log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s listen: 995 ssl_key_password: nerdie1tech login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_greeting: pilotalknet.dyndns.org ready. mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd What I need to ensure is that everything is correctly set for a pop3s server. I also need to know how to tell someone how to configure their mail client as the pop3 and smtp server. For example do I say pop.pilotalknet.ldyndns.org and smtp.pilotalknet.dyndns.org? The hostname is: pilotalknet.dyndns.org also is it still possible to check the working of the connection via a telnet connection doing: telnet pilotalknet.dyndns.org:995 or do I have to do something different? what I am achieving with the telnet connection is to ensure the pop server comes up with the greeting from dovecot. Thanks much.

[Dovecot] alternate sendmail binary for sieve redirect OT
by Robert Schetterer 12 Nov '10

12 Nov '10

Hi , this isnt really a dovecot/postfix question in dove lda, there is sendmail_path = someone tried other progs here like mini_sendmail ? http://www.acme.com/software/mini_sendmail/ i.e for using a default from forwarder address when sending redirects by sieve....is a stupid idea? background, some other mail providers use a default sender forwarder mailaddress when redirect this may avoid problems at forwarding with spf etc any other idea to reach this goal, pipe etc? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] correct syntax for multiple ports
by Kilburn Abrahams 12 Nov '10

12 Nov '10

Hi, What is the correct format to specify multple ports in dovecot 2. With dovecot 1.2 listen = *:143 *:6188 worked fine. I cannot find any mention in the wiki2 about the different combinations of listen, address and port parameters and dovecot complains about the combinations I tried. Does not seem to work 1. inet_listener imap { listen = *:143 *:6188 } 2. inet_listener imap { address = *:143 *:6188 } 3. inet_listener imap { port = 143, 6188 or port = 143 6188 } This start dovecot, but roundcube will not connect on port 143, although Thunderbird will connect on 1432 and 6188 listen = *, :: 1. inet_listener imap { port 143 port = 6188 } Regards K

[Dovecot] Phantom email message
by Marc Perkel 12 Nov '10

12 Nov '10

Got sort of a strange problem on one email account. Everything works fine with Thunderbird/IMAP showing the correct unread message count. But on my DroidX smartphone one of my email accounts always shows one unread message, but I can't bring any unread messages up. It's like there's something there making it think there's a message when there isn't. The email client is K-9 mail Anyone have any ideas?
