Hi Chris, I tried Evolution once about 10 years ago, and it was too complex and comprehensive for me to understand. The centerpiece of my emailing activity is a Dovecot IMAP server on my daily driver desktop computer. The way it works is that fetchmail grabs all my email from my various POP accounts, pushes them through procmail, whose filters distribute the emails into the proper Dovecot IMAP directories (and also /dev/null stuff from PITA people). As far as I know, my Dovecot has never malfunctioned. Currently, I access my local IMAP with Claws-Mail. Claws is capable, robust, and does what I need without being an ecological disaster like Kmail or intermittently pig slow like Thunderbird. Claws' configuration is difficult to wrap your head around, and very much in need of better documentation, but so far, thanks to a knowledgeable and helpful user community on the mailing list, I've been able to make almost every config change to speed my interaction with Claws. My one complaint about Claws that can't be cured by documentation is its propensity to do everything with one process and one thread, so while you're sending an email or scanning your IMAP, you cannot look at other emails. I also wanted their powerful search to be able to recurse folders, and when nobody volunteered to do it, I tried to do it myself. Making something recursive sounds like simply a matter of writing a simple loop around the existing functionality, but what I found out is, at least this part of Claws was written in a manner resembling MVC, with process and UI completely commingled. For that reason I was unable to make it recursive. I have Claws on my daily driver and all my laptops. Thanks to Kevin Korb's instructions, on the laptops I was able to tell Claws its IMAP server was at 127.0.0.1. I pinholed my OpenBSD/pf firewall appliance to port forward incoming ssh to my daily driver. Then, on my laptop, if I'm at home and on the LAN, I run the following inhouse.sh sudo ssh -NTL 993:127.0.0.1:993 slitt(a)192.168.1.88 While on the road I run this travelling.sh: sudo ssh -NTL 993:127.0.0.1:993 slitt(a)99.99.99.99 In the preceding, 99.99.99.99 is the IP address my ISP gave me, while 192.168.1.88 is the LAN IP address of my daily driver. This makes 127.0.0.1:993 get pushed through ssh to the ISP supplied internet address or the LAN address. So I can use Claws to interact with my daily driver desktop anywhere I go. I'm extremely pleased with this setup. My IMAP tree is trivial to back up, and gives me the assurance that if Claws-Mail ever commits suicide the way Kmail did when they went to Kmail2, I can simply plug in a different IMAP enabled email client. Meanwhile, Claws gives me an extremely productive and easy to use user interface. With my client/server setup, I no longer need to copy all my email too and from the laptop when travelling. I'm going to present on my remote use of my daily driver desktop Dovecot, using Claws and ssh, at tomorrow night's GoLUG meeting.

[Dovecot] Address extensions
by Armistead, Kurt 31 Jul '12

31 Jul '12

Hi guys, I'm trying to set up in-mailbox routing for messages using the + delimiter. The server runs postfix and dovecot 1.2.15. I have re-defined the delivery service in master.cf as "-f ${sender} -d ${user}@${nexthop} -n -m INBOX.${extension}" (server was formerly courier) but the routing only works when the destination folder has no uppercase characters. "Folder1" doesn't deliver correctly while "folder2" does. What am I doing wrong? Kurt

[Dovecot] mysql auth failover failing
by Paul B. Henson 29 Jul '12

29 Jul '12

We are running dovecot to provide authentication for postfix, using two mysql servers in a multi-master replication set as the password source: ---------------------------------------- # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-gentoo-r4 x86_64 Gentoo Base System release 2.0.2 auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = none service auth-worker { unix_listener auth-worker { user = postfix } user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = postfix } ssl = no userdb { driver = passwd } --------------------------------------- With an sql config of: ------------------------- driver = mysql connect = host=mysql-1.unx.csupomona.edu host=mysql-2.unx.csupomona.edu dbname=idmgmt user=postfix password=XXXXXXX default_pass_scheme = PLAIN password_query = XXXXXXXXX ------------------------- According to the sample SQL configuration file "HA / round-robin load-balancing is supported by giving multiple host settings, like: host=sql1.host.org host=sql2.host.org". However, as far as I can tell dovecot only connects to the first listed host, and processes all queries through it, there does not appear to be any load-balancing going on. That's not necessarily a dealbreaker; however, high-availability does not appear to be working either. If I shutdown the first mysql server, dovecot starts to log connection failures: Sep 9 15:47:34 tweak dovecot: auth: Error: mysql(mysql-1.unx.csupomona.edu): Connect failed to database (idmgmt): Can't connect to MySQL server on 'mysql-1.unx.csupomona.edu' (111) - waiting for 1 seconds before retry Sep 9 15:47:39 tweak dovecot: auth: Error: mysql(mysql-1.unx.csupomona.edu): Connect failed to database (idmgmt): Can't connect to MySQL server on 'mysql-1.unx.csupomona.edu' (111) - waiting for 25 seconds before retry And postfix starts to fail authentications: Sep 9 15:47:35 tweak postfix/smtpd[5119]: warning: bender.iitsys.csupomona.edu[134.71.250.134]: SASL DIGEST-MD5 authentication failed: Connection lost to authentication server Now and again the authentication process dies: Sep 9 15:47:39 tweak dovecot: auth: Panic: file auth-request-handler.c: line 697 (auth_request_handler_flush_failures): assertion failed: (auth_request->state == AUTH_REQUEST_STATE_FINISHED) Sep 9 15:47:39 tweak dovecot: auth: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x3f71a) [0x7f25822ca71a] -> /usr/lib64/dovecot/libdovecot.so.0(+0x3f766) [0x7f25822ca766] -> /usr/lib64/dovecot/libdovecot.so.0(+0x198ca) [0x7f25822a48ca] -> dovecot/auth() [0x4137f4] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xd4) [0x7f25822d5fe4] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x5b) [0x7f25822d6bcb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f25822d5c48] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f25822c3de3] -> dovecot/auth(main+0x2be) [0x4179de] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x7f2581898bbd] -> dovecot/auth() [0x40bdc9] Sep 9 15:47:39 tweak dovecot: master: Error: service(auth): child 4154 killed with signal 6 (core dumps disabled) Requests start to pile up: Sep 9 15:51:46 tweak dovecot: auth: Warning: auth workers: Auth request was queued for 25 seconds, 45 left in queue Lookups time out: Sep 9 15:57:22 tweak dovecot: auth: Error: auth worker: Aborted request: Lookup timed out This occasionally pops up: Sep 9 15:58:38 tweak dovecot: auth: Fatal: net_connect_unix(auth-worker) failed: Resource temporarily unavailable And sometimes the auth process gets temporarily disabled: Sep 9 15:58:57 tweak dovecot: master: Error: service(auth): command startup failed, throttling Resulting in more postfix authentication failures: Sep 9 15:58:57 tweak postfix/smtpd[6531]: warning: bender.iitsys.csupomona.edu[134.71.250.134]: SASL DIGEST-MD5 authentication failed: Sep 9 15:59:08 tweak postfix/smtpd[6551]: fatal: no SASL authentication mechanisms To the point where postfix also temporarily throttles smtpd: Sep 9 15:59:21 tweak postfix/master[6526]: warning: /usr/lib64/postfix/smtpd: bad command startup -- throttling Resulting in a complete unavailability of smtp service, not just unavailability of authenticated services. I don't think all authentications fail during the scenario, but I think the majority do. Based on the network traffic, dovecot is almost continuously trying to connect to the first listed server. It sometimes connects to the second listed server, but when it does, the connection does not persist, it goes away almost immediately. Ideally, I would like no authentications to fail if one of the MySQL servers is unavailable. If a few fail just when the server dies, that would be undesirable but acceptable as long as they do not continuously fail while the server is down. Am I doing something wrong? Does the example sql config have incorrect information? We were previously running dovecot 1.2.11, we just recently upgraded to 2. In the previous version, we actually had two different passdb's configured, each one listing only one of the mysql servers. I seem to recall that was the recommendation at the time for high-availability. When that configuration did not seem to work under version 2, I found an updated recommendation to list both servers in the same passdb, which also does not appear to work correctly. I actually went back and tested the older version, and determined it seemed to work okay in the case where the server was up but the service was down, and connections were refused, but also failed a large number of authentication attempts when the server was completely down and connections were timing out.

[Dovecot] Problem with preserving MIME format with Dovecot IMAP and Outlook
by Peter Grimmond 29 Jul '12

29 Jul '12

Hello, I have installed Dovecot 2.0.19 on Ubuntu 12.04 LTS. I have set up a very basic IMAP configuration. I have two different laptops running Outlook (one MacOS, one Windows 7) and I have configured both to connect to the Dovecot service. My problem is, emails in MIME format that I synchronise from one Outlook client are not being correctly decoded as MIME messages on the other client. Instead, the message is rendered in plaintext, starting with the lines: This message is in MIME format. Since your mail reader does not understandthis format, some or all of this message may not be legible. --B_3426360453_22814Content-type: multipart/alternative; boundary="B_3426360453_4099" --B_3426360453_4099Content-type: text/plain; charset="ISO-8859-1"Content-transfer-encoding: quoted-printable Can anyone help me understand why this might be happening? The output from dovecot -n is: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-26-generic-pae i686 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:~/Maildir passdb { driver = pam } protocols = " imap" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Thanks!

[Dovecot] Dsync replication
by list＠airstreamcomm.net 28 Jul '12

28 Jul '12

I have been loosely following discussions dsync replication, but I am wondering if this tool still in a testing phase or has it been committed as a production part of Dovecot? I would like to do some testing with the protocol to see if it's capable of handling the change rate our mail service generates, which has about 23,000 active users. We are trying to find solutions for a two site setup where mail processing is either being done at the primary data center A and fails over to a hot standby cluster at the secondary data center B, or where both data centers are doing active processing. I have been unable to find documentation on dsync replication on the wiki, so if there is any documentation available on how to setup dsync replication I would appreciate a nudge in the right direction.

[Dovecot] fts-lucene vs SEARCH HEADER
by Matthew Powell 28 Jul '12

28 Jul '12

Hello. This is in Dovecot 2.1.7 on Linux x86, but it looks as though 2.1.8 has the same issue. I'm using fts-lucene. SEARCH HEADER TO returns no results, but SEARCH TO works: B SEARCH TO TEST * SEARCH 1 2 3 4 5 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 24 26 27 28 29 31 B OK Search completed (0.000 secs). C SEARCH HEADER TO TEST * SEARCH C OK Search completed (0.000 secs). Without FTS enabled, both forms of the query work. It looks as though the header names are indexed in lower case. But Dovecot is passing the header name to the backend in upper case when SEARCH HEADER is used. I'm not sure whether this is the *right* fix, but lower-casing the header name in lucene-wrapper.cc seems to fix the problem: --- dovecot-2.1.7-clean/src/plugins/fts-lucene/lucene-wrapper.cc 2011-12-13 06:35:29.000000000 -0500 +++ dovecot-2.1.7/src/plugins/fts-lucene/lucene-wrapper.cc 2012-07-24 14:03:14.000000000 -0400 @@ -1094,7 +1094,7 @@ return false; q = lucene_get_query(index, - t_lucene_utf8_to_tchar(index, arg->hdr_field_name, FALSE), + t_lucene_utf8_to_tchar(index, t_str_lcase(arg->hdr_field_name), FALSE), arg); break; default: Now: B SEARCH TO TEST * SEARCH 1 2 3 4 5 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 24 26 27 28 29 31 B OK Search completed (0.000 secs).

[Dovecot] Auto logging-out client
by Nicolás 28 Jul '12

28 Jul '12

Hi list! I'm writing because of an issue I'm having with my Postfix-Dovecot installation. Everything's working fine but when an IMAP client is idle for some time, Dovecot automatically logs it out. Jul 26 14:01:16 mail dovecot: imap(nicolas(a)devels.es): Disconnected: Logged out bytes=1271/7439 This entails errors when trying to send e-mails after this auto logout, such as: host devels.es[91.215.158.237] said: 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message. Which result in a very annoying and continuous proccess of restarting my mail client. Is there a way to avoid this auto-logout, or at least configure the time after I want idle clients to auto-logout? Thank you very much! Nicolás

[Dovecot] Slightly OT - Winbind and remote authentication.
by Simon Brereton 28 Jul '12

28 Jul '12

Hi I was doing some research on setting up a samba server for my internal network (as an alternative to NAS). The setup looks easy enough, but then I got to thinking - I already have an internet host with an mysql DB that has usernames and passwords and it would be simpler all round to reuse that as the authentication server. That server is also running Dovecot, so I thought it might be simpler still to set up samba to authenticate using IMAP (the mysql server is not accessible on port 3306 anyway). A quick google resulted in a suggestion from Robert (who by now must be on every single list I'm on or rather vice-versa) about using winbind. I went off to the link he posted - http://wiki.dovecot.org/Authentication/Mechanisms/Winbind?highlight=%28winb… and the problem is that seems to indicate bind and dovecot are on the same server. So, this not being the samba list notwithstanding, is it possible to use a remote dovecot host as an authentication back-end on a local samba installation? Cheers Simon

[Dovecot] Problem overriding default quota limit
by RAUL JAREÑO MORAGO 28 Jul '12

28 Jul '12

Hi, We get user's quota limit from LDAP. It works fine when user has quota attribute in LDAP (this is when it's different from default quota). But when user doesn't have quota limit attribute Dovecot doesn't take default value defined in quota plugin and assign unlimit quota to user. Our configuration is similar to the example from wiki ( http://wiki2.dovecot.org/Quota/Configuration ). This is the plugin configuration _plugin {_ _ quota = maildir:User quota_ _ quota_rule = *:storage=1G_ _ .........._ _}_ And this is the recovered fields in LDAP search: _user_attrs = mailMessageStore=home,mailquotasize=quota_rule=*:bytes=%$_ It works if user has mailquotasize in its LDAP entry. But if it hasn't it Dovecot assign 0 instead of *:STORAGE=1G This is the log when LTMP deliver a mail to a user without mailquotasize attribute: _auth: Debug: master in: USER#0111#011eepp68#011service=lmtp#011lip=172.31.100.120#011lport=24#011rip=172.31.100.119#011rport=41452_ _auth: Debug: userdb-cache(eepp68,172.31.100.119): miss_ _auth: Debug: ldap(eepp68,172.31.100.119): user search: base=o=Junta de Castilla-La Mancha,c=ES scope=subtree filter=(uid=eepp68) fields=mailMessageStore,MAILQUOTASIZE_ _auth: Debug: ldap(eepp68,172.31.100.119): result: mailMessageStore=/buzones1/e/eepp68; MAILQUOTASIZE MISSING_ _auth: Debug: master out: USER#0111#011eepp68#011home=/buzones1/e/eepp68#011QUOTA_RULE=*:BYTES=_ _lmtp(8235): Debug: auth input: eepp68 home=/buzones1/e/eepp68 quota_rule=*:bytes=_ _lmtp(8235): Debug: Added userdb setting: plugin/quota_rule=*:bytes=_ _lmtp(8235, eepp68): Debug: Effective uid=11184, gid=2110, home=/buzones1/e/eepp68_ _lmtp(8235, eepp68): Debug: Quota root: name=User quota backend=maildir args=_ _lmtp(8235, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0_ I tried it with defining default_fields in userdb but I get the same result: _userdb {_ driver = ldap args = /etc/dovecot/dovecot-ldap-lmtp.conf.ext default_fields = quota_rule=*:bytes=1073741824 } If I don't recover mailquotasize (user_attrs = mailMessageStore=home) Dovecot assign default quota limit, so it works in this case: auth: Debug: master in: USER#0111#011eepp68#011service=lmtp#011lip=172.31.100.120#011lport=24#011rip=172.31.100.119#011rport=41427 auth: Debug: userdb-cache(eepp68,172.31.100.119): miss auth: Debug: ldap(eepp68,172.31.100.119): user search: base=o=Junta de Castilla-La Mancha,c=ES scope=subtree filter=(uid=eepp68) fields=mailMessageStore auth: Debug: ldap(eepp68,172.31.100.119): result: mailMessageStore=/buzones1/e/eepp68 auth: Debug: master out: USER#0111#011eepp68#011home=/buzones1/e/eepp68 lmtp(8198): Debug: auth input: eepp68 home=/buzones1/e/eepp68 lmtp(8198, eepp68): Debug: Effective uid=11184, gid=2110, home=/buzones1/e/eepp68 lmtp(8198, eepp68): Debug: Quota root: name=User quota backend=maildir args= lmtp(8198, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 Any idea about where is the problem?

The default is not taken since your LDAP query returns a quota_rule with an empty bytes= value when the mailquotasize entry is missing.

[Dovecot] emails are being marked as read auto-magically
by Joe Beaubien 28 Jul '12

28 Jul '12

Hi, I'm having a weird issue with dovecot 2.1.7 (using the latest thunderbird client). Something, I have emails that mark themselves as read on their own. No one touches them, and they get marked as read. I try to re-mark them as unread, but a few seconds later, they get marked as read again. The same problem happens in reverse (emails marks as unread become read). Has anyone ever experienced anything similar? I cannot see any warnings or errors in the dovecot logs, so I'm not sure if the problem is with thunderbird or with dovecot. However, I have never had this issue before switching from dovecot 1.0.X to dovecot 2.1.X. Unfortunately, we updated the thunderbird versions around the same time, so I feel like a dog chasing my tail on this issue. Any help would be appreciated. Regards, -Joe

I don't think anybody can give you any concrete idea of how to change your dovecot setup without a lot more information. It appears to me you'll have to do a clean re-do of your dovecot setup, using your old configuration as a reference. Joseph Tam <jtam.home(a)gmail.com>

I just tried configuring the submission port on postfix but the problem persists even sending by port 587. About what Harald said, I guess I initially missed the point of the problem, it was just my conclusion because that error happens always after the logout message appears, and SMTP authentication is set on my client, so I deduced the problem had something to do with the logout thing. The curious thing is it just happens with SMTP, not with POP3/IMAP protocols. Thanks again! Nicolás

[Dovecot] Sieve & Adding headers.
by Steven Haigh 26 Jul '12

26 Jul '12

Hi all, I've just migrated my mail system from procmail to managesieve/sieve and I'm having trouble trying to duplicate a could of rules I used to use in my procmail config. One particular rule would be this: :0 Wfh * ^Sender: owner-scientific-linux-devel(a)LISTSERV.FNAL.GOV | (sed -e '/^Subject:/ s/\[SCIENTIFIC-LINUX-DEVEL\] *//g'| sed ':a;N;$!ba;s/Precedence: list/Precedence: list\nList-Post: <mailto:scientific-linux-devel@fnal.gov>/g') :0 A .Mail\ Lists.SL-Devel/ This in effect adds the header "List-Post: <mailto:scientific-linux-devel@fnal.gov>" after "Precedence: list". This allows me to use the Reply To List functionality in Thunderbird. Another rule is: :0 Wfh * ^X-BeenThere: users(a)lists.repoforge.org | sed -e '/^Subject:/ s/\[users\] *//g' :0 A .Mail\ Lists.RPMForge/ This removes the [users] tag from the subject of each message to the RPMForge / RepoForge mailing lists. Is there a way to do this with sieve? Nothing I have seen seems to do this - however I'm only a beginner in this area. Please CC myself as well as the list. I'm not currently subscribed. -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299

We are running dovecot-1.2.10 on a Solaris 10 x86 host.

What is common with the three users is that they are using alpine mail client. Again these just started on July 24. We have over 300 user and a lot of them use alpine but only three users seem to generate these lock files. Can some one tell me what and why these are being created and why they are not getting destroyed? Thanks Robert _____________________________________________________________________ Robert P.

[Dovecot] deleted-to-trash plugin problems
by Steve Platt 24 Jul '12

24 Jul '12

We have a user who wants to use Outlook with our Dovecot IMAP server but doesn't like the way Outlook handles deletion with IMAP. Ironically she would like Outlook to move the message to her Trash folder, just like Outlook does with "local" folders, I guess. So I enabled the "deleted-to-trash" plugin (v0.3) on our Dovecot 1.2.17 server (built for SPARC, solaris 10, btw). The problem is that it doesn't seem to work; the message doesn't even appear to get marked for delete. The imap log says: "opening Trash succeeded" and then nothing else! I have found that there is a copy of the message in .Trash/tmp/ suggesting that the plugin may be bailing out part way through. Has anyone any idea what's wrong please? I'll attach the output of dovecot -n ... Thanks, Steve

Morten Stevens <mstevens(a)imt-systems.com> writes: > So it is now RFC compliant. Anyway I think delaying mail traffic is not > a good solution. Well, OK, if you not keen on greylisting, you can try greet pausing, which introduces a shorter delay. It tests a bot's patience by inserting a pre-HELO pause. RFC allows 5 minutes before timeout. This is last week's stat for one of my mail server and the count of early-talker or early-disconnecter, almost all of which are bots. A greet pause of over 20s dumps a lot of bots. Expect to whitelist the odd server here and there because they've tuned their servers to some aggressively small RFC non-compliant timeouts.

That's another problem with the poor IT guy trying to assemble bricks from different vendors: when he finally is heard, the answer is "uhm, the feature you requested fail beyond the scope of my brick. I'm sorry, I can't do that", even when there is a proposed patch available! If you read carefully all my referenced links you'll find one that is listing other imap servers that support it.

Unfortunately that feature only addresses PROVISIONING of data, which is quite unuseful since cyrus mail admins do this with the auto-* uoa.gr patches (that's another pain that devs refused to include for a long time) - What it lacks is the ability to handle CHANGE (change of default script, or alter existing user scripts).

[Dovecot] Couple of questions about the logs
by Steve Campbell 23 Jul '12

23 Jul '12

The log entries for imap disconnection shows a "bytes = x/y" format where the x equals bytes sent from client and y equals bytes received from client. Can someone explain that a little better to me, please? In an imap account, does this "y" represent the size of the header information being returned to the client or the amount of data of the email mailbox? Also, is there a way to tell if an email has been deleted (or marked for deletion) when using an imap client? Here's the situation: I've got a user who uses imap when using his phone and webmail. When in the office, he uses a pop3 client on his desktop. He indicates he's missing some emails from the weekend when first turning on his desktop. I know of no way to discover if he's deleted and then purged email from his mailbox using imap clients. I've checked the logs and he does not access his mailbox simultaneously from any of the 3 clients. I can find 31 emails he received since his last pop login on Friday until his first pop login on Monday. The pop login indicates he received only 27 emails during the pop retrieval. I'm a little lost here. Any help would be appreciated in interpreting the logs or suggesting how this might have happened. thanks steve campbell

[Dovecot] Performance based choices
by Hans J. Albertsson 22 Jul '12

22 Jul '12

I've stopped trying to find a HowTo that suits me right away, and instead I am happily trudging thru the Dovecot wiki, article by article. I have right up front thought of one question, a general one, and some detailed versions of that same question: Generally, is there much general performance and reliability background data available for making the basic choices? Say: 1st. delivery: maildrop or LDA or LMTP? I tend to think LMTP should be the ideal choice for me, from what I've gleaned so far. Above all it means that there's only one conceptual thing that needs to know, and postfix and other stuff can safely let dovecot deal with accessing and finding mailboxes. And it won't start and stop thousands of processes. 2nd. mailbox format: Maildir and mbox are the older forms. Are there any advantages to using dovecot's dbox instead? mdbox strikes me as having the potential for being a fast and reliable format. Is that an accurate impression? And, is mdbox mature enough for me to forget maildir and mbox? 3rd. I'm aiming for a poor man's High Availability system: I'm using zfs, and I'm hoping to place all config data for dovecot and postfix and everything else in one zfs file system, and all the user owned data (what should normally go in a home directory) in another (or two or three other) zfs file systems. Then I'm planning to copy over all data at regular intervals, to a second, normally passive, mail server. If the main server breaks, we'll manually (or using scripts and autodetection) fail over to the passive one, making it active, and turning power off to the failed guy using IPMI. The data transfer is to be zfs send/zfs recv over a separate highly redundant network connection. Is this a reasonable idea, or is there some advantage to letting dsync do some of the copying??? Or is there some totally different alternative? iscsi? 4th. With about a thousand users/accounts: does MySQL pay off? Or is LDAP the way to go? Or will a dovecot-specific passwd-file do the job well enough? Those are the three I'm used to since before. I'd like to stay with the flat file, but not the system password file: we're not going to let users in except into dovecot.

[Dovecot] Corrupted dbox file - purging found mismatched offsets

Hi, we are running a cluster using mdbox on NFS with director+mailbox on each node. After running our daily doveadm purge loop over all users, we got dbox corruption... doveadm user "*" |\ while read username do doveadm -c /etc/dovecot-director/dovecot-director.conf -D purge -u "$username" done For one user (which deleted a lot of messages from his mailboxes today), we got the following error in the dovecot.log: Jul 22 20:10:36 10.129.3.213 dovecot: doveadm(user(a)example.org): Error: Corrupted dbox file /mail/dovecot/example.org/user/mail/storage/m.24 (around offset=1380859): purging found mismatched offsets (1380829 vs 920527, 3/61) Jul 22 20:10:36 10.129.3.213 dovecot: doveadm(user(a)example.org): Warning: mdbox /mail/dovecot/example.org/user/mail/storage: rebuilding indexes What does this message exactly tell me and how to prevent this in the future?

[Dovecot] Confusion when trying to set up a first postfix+dovecot mailserver
by Hans J. Albertsson 22 Jul '12

22 Jul '12

I'm trying to set up a first test for a dovecot + postfix (+ many other things) mail server for about 1000 accounts, and I keep stumbling on confusing inconsistencies in the HowTo documents I'm trying to follow. I tried to do a simple setup with virtual users using a howto saying it was for just that and that it's for Dovecot 2.x, and it shows a few text chunks to put in files, and then says it's better to do the changes in the example-config conf file.... And then the whole structure of config files and dirs is totally different from what is implied in the howto. And of course it won't run. Probably because of the structure of a conf.d dir is multiple files, and the instructions are explicitly written for the case of having a single conf file. Can anyone suggest an order in which to read docs that will take me thru w/o being totally confusing? I would very much like to be able to enable bit by bit, rather than have to understand all of dovecot before I can even begin to test it. P.S: I want to setup a server using postfix+dovecot+tls+virtualusers+maildir+dspam+mailman, at least that's the target I'm aiming for. Please suggest a good HowTo for this setup that will not be too confusing. Also, Sorry if I sound like a whining kid: I am new to dovecot and postfix, but I was a software support engineer for Sun for ages, and I should really be able to manage this if I just had some consistent and non-confusing HowTo or Tutorial to follow as a first try.

[Dovecot] postfix/sendmail configuration
by Gary Partis 20 Jul '12

20 Jul '12

Hi all I have searched the net and cant find anything relating to this. In 15-lda.conf, the default sendmail is used to send messges from Dovecot, such as "out of hours" and "redirected" emails controlled by sieves. However, postfix/sendmail is looking in /etc/postfix/main.cf for the configuration file (as logged in /var/log/maillog), but I have the config file elsewhere, and I even have MAIL_CONFIG setup to point to the true config directory. Is there a method of setting 15-lda.conf sendmail config to ensure it uese the correct postfix config file? Thanks in advance Gary

Failing that, though it'll mean a LOT of work for me to manually convert all of the existing Maildirs, how do I get dovecot to work in future in MBox single file format. I tried entering 'mail_location = mbox:~/mail:INBOX=/%h/%u' in the 'dovecot.conf', but it still saves each message in a file of its own in the /new /cur /tmp directories ??

[Dovecot] Make a whole mailbox read-only
by Sandro Tosi 19 Jul '12

19 Jul '12

Hello, i've found an old thread [1] where it was stated that a whole mailbox can be made read-only only setting the according permissions on the filesystem side. [1] http://www.mailinglistarchive.com/html/dovecot@dovecot.org/2011-12/msg00300… i'd like to check if it's still the only option we have with dovecot v2.0.18 .

Whilst I would normally agree, at the same time I've had a fair amount of experience with dovecot and sendmail (been running them for over 10 years). Pigeonhole is new to me, however. . . > One thing I did notice is that you are sending this mail from an internal IP... since most people use very different checks for such mail (bypassing many/most checks), maybe you should be testing from an external address (one that comes in from outside your network)? So I have a DMZ that houses the mail server for my domain, which is where the private addresses are. Connections are passed through the OpenBSD router to the mail server. So testing from an external address would be essentially the same (since the connection to the SMTP server talks to the sendmail process as the /usr/lib/sendmail process). Regardless, my original tests were sending mail from the Mac off-network. > Also, it is always recommended when setting up a new server to start with the latest version... for 2.0.x that would be 2.0.19, but the latest is 2.1.8... When I set it up, 2.0.13 _was_ the latest. :-) I was hoping to avoid the pain of recompiling dovecot and pigeonhole. Not that big a deal, I guess. . . >> lda_original_recipient_header = X-Original-To >> lmtp_save_to_detail_mailbox = yes > > Ok, I think this is the problem... > > Dovecot's LMTP currently does NOT preserve the x-original-to header... in fact, brought this up recently (I was one of the ones interested in Timo adding support for it) on this (and the postfix, which is what I use) on this very list: > > http://www.dovecot.org/list/dovecot/2012-April/065075.html > > Apparently, after Timo discussed this on the postfix list, he determined that it would not be a very significant change for him to make to add support for this header in LMTP and that he would get to it sooner than later, but as of now, it has not been added. Actually, I'm not using lmtp. I whacked the lmtp_save_to_detail_mailbox in an effort to see if that was the issue before I realized I don't have it turned on. dovecot.conf has: protocols = imap though in 20-managesieve.conf I have: protocols = $protocols sieve I just turned it off and restarted dovecot (though lmtp was not running) and re-ran the test with the same result. So, I think what's going on is pretty straightforward. The local mailer definition in the sendmail.cf file is: Mlocal, P=/usr/local/libexec/dovecot/dovecot-lda, F=lsDFMAw5:/|@qSPhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u This is more or less right out of the wiki. Since dovecot-lda is passed the -d option, it's using that (and only that) for delivery. Since there's no X-Original-To: header, it doesn't really have any option (since the non-envelope-to address might not exist, or point to something other than the end user's mailbox, etc). It would appear that I have two options: 1) Figure out what macro(s) is(are) valid to pass to dovecot-lda with the -a option in the sendmail config file (sendmail.cf). 2) Get sendmail to put "X-Original-To: <address>" in the header. Both would appear to be a sendmail issue, not a dovecot/pigeonhole issue. Everything I find on the web seems to center around how to use plus addressing to accept mail from multiple email address and filter it into a single address for delivery, only to have the local delivery agent break it back out again. That's not my issue. :-( Sean Sean

[Dovecot] doesn't work at all

Hi, I can't seem to get dovecot to work. When I connect with thunderbird, tbird complains that it can't find the settings for my email. When I connect with evolution, it seems to go through all the motions but it doesn't pick up the waiting messages. Those messages are marked Status: O s if it had read them.

[Dovecot] SQLite dovecot query caching
by Dominic Malolepszy 19 Jul '12

19 Jul '12

Hi, I am wondering if Dovecot caches SQLite queries, and how well it works in high performance setups. I am particularly interested because in the below thread SQLite has been suggested as a means of Dovecot proxying connections to different ports. http://old.nabble.com/director%3A-non-standart-ports-at-backends-td33991991… Cheers, Dominic.

[Dovecot] MySQL dict issues
by list＠airstreamcomm.net 18 Jul '12

18 Jul '12

Testing using the mysql dict for quota storage (dovecot-2.0.12-2_127.el5), and ran into a couple issues. First is a permissions issue: dovecot: lmtp(26786, dude(a)test.tld) Error: net_connect_unix(/var/run/dovecot/dict) failed: Permission denied (euid=5000(<unknown>) egid=5000(<unknown>) missing +r perm: /var/run/dovecot/dict, euid is not dir owner) The file /var/run/dovecot/dict is listed with srw------- perms. I changes the perms to srw----rwx and it works, but I would like to figure out how to configure properly to run with the uid and gid 5000 as this is the user for virtual mail. The second issue is that two identical rows are created in the mysql database for each user quota. The next message delivered updates both rows. Here is my quota config: 90-quota.conf: plugin { quota_rule = *:storage=10G quota_rule2 = Trash:storage=+10% } plugin { quota = dict:user::proxy::userquota } dict { userquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } dovecot-dict-sql.conf.ext: connect = host=a.b.c.d dbname=mail user=user password=derp map { pattern = priv/quota/storage table = domain_user_quotas username_field = username value_field = bytes } map { pattern = priv/quota/messages table = domain_user_quotas username_field = username value_field = message_count } The last issue might be a documentation omission. Dovecot warned me that the mysql user did not have DELETE privileges on the quota table: dovecot: dict: Error: sql dict: commit failed: DELETE command denied to user 'user'@'a.b.c.d' for table 'domain_user_quotas' The quota dict documentation (at http://wiki2.dovecot.org/Quota/Dict) does not mention DELETE being needed: MySQL uses the following queries to update the quota. You need suitable privileges. INSERT INTO table (bytes,username) VALUES ('112497180','foo(a)spam.dom') ON DUPLICATE KEY UPDATE bytes='112497180'; INSERT INTO table (messages,username) VALUES ('1743','foo(a)spam.dom') ON DUPLICATE KEY UPDATE messages='1743'; UPDATE table SET bytes=bytes-14433,messages=messages-2 WHERE username = 'foo(a)spam.dom';

[Dovecot] expire-tool stops on first box with nothing to expire in it
by Michael Wessel 18 Jul '12

18 Jul '12

Hi, I'm running dovecot 1.2.11 on Centos and have the expire plugin enabled. I've had this in place for some time but until now never actually ran the expire-tool. I'm now trying to put this to use. The expire plugin as such is working fine and also the tool is working fine - up to a point. When I run it with --test it goes through a bunch of boxes and lists the messages it would expunge and the new date being logged at the end. As soon as it hits the first box that has nothing in it that's expired however, it stops and goes no further. As an example here are the last two lines of the output when I just ran it: Info: user(a)domain.com/Trash: timestamp 1342320464 (Sat Jul 14 19:47:44 2012) -> 1342937319 (Sat Jul 21 23:08:39 2012) Info: nextuser(a)domain.com/Trash: stop, expire time in future: Sat Jul 14 20:41:49 2012 If I run it again after the indicated expire time it will now also go through the nextuser(a)domain.com but then again stop as soon as it encounters another user with nothing to expire. As far as I can tell the same happens when I actually run the tool. Harder to tell of course as there is no output, but I can tell that not all boxes are expunged as they should be. Any ideas why this would be? Any way to get debug logging on this? Michael

[Dovecot] Compile issue Dovecot 2.1.8, OS X 10.6.x
by Jim 18 Jul '12

Hey all. I'm running Mac OS X 10.6.4, and had Dovecot 2.0.7 installed built from source. I'm now wanting to upgrade to Dovecot 2.1.8, but I can't get MAKE to finish without errors: ./configure --with-mysql (snip) Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : kqueue I/O notifys .... : kqueue SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file pam checkpassword sql : -shadow -bsdauth -sia -ldap -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword sql : -ldap -vpopmail -nss SQL drivers .... : mysql : -pgsql -sqlite Full text search : squat : -lucene -solr sudo make (snip) Undefined symbols: "_libiconv_open", referenced from: _charset_to_utf8_begin in libcharset.a(charset-iconv.o) "_libiconv", referenced from: _charset_to_utf8_reset in libcharset.a(charset-iconv.o) _charset_to_utf8 in libcharset.a(charset-iconv.o) "_libiconv_close", referenced from: _charset_to_utf8_end in libcharset.a(charset-iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status make[3]: *** [libdovecot.la] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 The reason for the 'sudo make' was to get around a permissions issue, but I don't think that's related to my issue here. I had build Dovecot 2.0.7 and earlier without issue on this system, but I'm a bit stumped on this particular problem. I also found that the configure parameter --with-sql-drivers no longer seems to work, even though it's still shown in the wiki for 2.x. As far as I can tell, I had used this parameter when compiling 2.0.7.

[Dovecot] Different LDAP filters for different protocols
by James Devine 18 Jul '12

Is it possible to query LDAP differently for different protocols? I am using dovecot for both pop3/imap and lmtp deliveries and there are different enable flags in ldap for them. I tried wrapping user_filter inside the protocols in the file dovecot-ldap.conf.ext as shown below but this didn't seem to work. protocol lmtp { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(msmtp=1)) } protocol imap { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(mpop=1)) } protocol pop3 { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(mpop=1)) }

[Dovecot] outlook and redirect sieve
by Lazy 17 Jul '12

17 Jul '12

Hi Aall, we are having issues with outlook clients, running exchange or lotus being unable to parse the email messages redirected by dovecot's sieve 0.3.1, the command is plain redirect "email(a)lotusmail.xxx"; redirects from mta also work correctly exchange was fixed by removing this commit http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-diff/082216ad12d6/src/lib… are there any other modifications to the email body or headers that can make those mesages not parsable for outlook ? looking at http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-diff/082216ad12d6/src/lib… maybe removing HEADER_FILTER_NO_CR fromi_stream_create_header_filter() will make redirected messages more in tact ? what can I do to make redirect more verbatim ? Thanks in advance for any information. Regards, Michal Grzedzicki

[Dovecot] Selective TLS per local IP
by Robert Blayzor 17 Jul '12

17 Jul '12

We have the requirement to provide SSL on some IP addresses, but not others on our servers. Providing SSL is the easy part and we're able to use multiple SSL certificates now. (thanks Timo!) All is working ok, but we several IP hosts that do not require SSL and do not have valid certificates. While we can limit access via a firewall ACL to TLS connect ports (993/995) we can't do so on port 110/143. The problem is that some clients now are smart enough to look for an offered STARTTLS or STLS, and if it's offered, they try to use it. While not normally a problem if your setup for SSL with valid key/certs, if you have a self signed or no CERT at all, it starts connection warnings and errors on the client side. So is there any way possible to turn off advertising of TLS on port or turn it off/on per IP? Something like: ssl = yes ssl_cert = </etc/ssl/cert/default.pem ssl_key = </etc/ssl/cert/default.pem local 10.1.1.1 { protocol imap { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } protocol pop3 { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } } local 10.1.1.2 { ssl = no } *or* ssl = no local 10.1.1.1 { ssl = yes protocol imap { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } protocol pop3 { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } } -- Robert Blayzor INOC, LLC rblayzor(a)inoc.net http://www.inoc.net/~rblayzor/

[Dovecot] [PATCH] Interop problem with Cyrus SASL and GSSAPI
by Ben Morrow 17 Jul '12

17 Jul '12

[I sent this a while ago, but it seems not to have made it to the list. I'm resending it having subscribed first; I apologise if anyone get it twice.] I have been trying to get a Postfix mail server using Dovecot SASL to accept GSSAPI AUTH from another Postfix server using Cyrus SASL, and I believe I have found a couple of bugs in Dovecot's GSSAPI implementation. The first problem is that, because of the way the client invokes libsasl, it sends a GSSAPI request which does not ask for mutual authentication. This means that on the server gss_accept_sec_context returns GSS_S_COMPLETE with a zero-length output token. Dovecot currently sends this to the client as a zero-length continuation response, but this is incorrect according to RFC 4752: what it ought to do instead is proceed straight to the security layer negotiations, and send a gss_wrap packet. The second is that Cyrus sends an empty authz identity; that is, the security layer negotiation packet, when gss_unwrapped, is exactly 4 bytes long. Dovecot objects to this, but in RFC 4422 this is explicitly allowed, and means the authz identity is identical to the authn identity. I believe the attached patches (for the 1.2 and 2.1 branches) fix the problem, though I'm not entirely sure if the difference between the p_strndup in mech_gssapi_unwrap and the t_strndup in get_display_name is important.

[Dovecot] Feature request
by Malloc Kilobyte 17 Jul '12

17 Jul '12

Hi, I am implementig Dovecot as a part of my new e-mail server, which is aimed to be replacement for proprietary software I've been using sofar. Appreciating all Dovecot rich features, I lack just one. And this is the ability to customize the "quota exceeded, message rejected" message. I know I can set it's default content using quota_exceeded_message parameter, but i would also like to have ability to set: - to whom the message is sent. Some mail systems send copy not only to the sender, but also to the recipient. It makes sense in case rejected message has big size. - it's subject - if the rejected message is being attached ( with or without it's own attachments ) or not Moreover, I think it would make sense if the "rejected messege" contained information about size of rejected message and current mailbox space usage. Please, consider this in future development. with regards and respect to the tremendousness of Dovecot, -- malloc4k

[Dovecot] doveadm director status username != doveadm director status username@mailserver
by Joseba Torre 17 Jul '12

17 Jul '12

Hi, I've almost finished my new director based setup, but in the first test I discovered that imap and lmtp connections were not always being proxied to the same server. After some research now I think that the main problem is that in imap connections users connect as 'username' while lmtp connections are as 'username@mailserver'. In my current setup I receive mail via SMTP in my director servers (which are loadbalanced by a CISCO machine), and then they send them to dovecot running on localhost. I've tried to get rid of the @mailserver in postfix in a generic way with no success. Is there any way to redirect connections based only in the local part of the address? Or there is a way to get rid of the @mailserver in the postfix -> lmtp connection? Both doveadm config -n and postconf -n are attached.

We don't use passdb in the directors because incoming mails have already been checked by postfix, and the final mail server need to check our ldap server for other values, so we check there.

[Dovecot] imapc: Restrict the number of connections
by René Neumann 17 Jul '12

17 Jul '12

Hi, I have managed to get an imapc connection to another server and bind its contents to only one account (via global ACL). The namespace itself is created as public, though it does not seem to make a difference for this use case (i.e., it does not matter, whether its type is 'public', 'shared', or 'private'). namespace { hidden = no list = children location = imapc: prefix = Gemeinsam. separator = . subscriptions = no type = public } One problem remains: Though there is only one account that is allowed to use this imapc-connection, each imap-process opens a connection to the imapc'd server. Is this caused directly by the imapc_*-definitions in the config? Or is there a way of restricting this to only the account which actually uses it. Used dovecot version: 2.1.8 Thanks, René

[Dovecot] Last login datetime on accounts
by Robert Blayzor 16 Jul '12

16 Jul '12

I have searching for the best way to tell if a Dovecot user is idle by finding the last time they have logged in. Right now the best way I can tell is to do something like "touch" a file in the users homedir via a post login exec. This seems like a LOT of overhead, to accomplish such a simple task, especially if your doing a lot of dozens of logins per second. Is there an easier/better way? Is there a way to possibly tell Dovecot to refresh the mod time on an index file whenever the user successfully auths or to refresh a separate file in the homedir, ie: ~/.lastlogin (not ~/Maildir/.lastlogin as that would obviously cause some issues) Seems like something that would be far less overhead than calling a shell, execing another command, etc. I'm open to other ideas/alternatives if they are out there!

[Dovecot] Multi Server Exim/Dovecot and NFS
by Robert Blayzor 16 Jul '12

16 Jul '12

In reading the Dovecot NFS WIKI entry: http://wiki2.dovecot.org/NFS It mentions a FreeBSD NFS client caching bug. I believe that bug only exists pre-8.x ? It seems that a patch in the PR notes was MFC'd and made it into 8.x at some point. (at least I checked the source in 8.3 and it was there). So I assume that FreeBSD 8.x mitigates the issue? Maybe not? So our deployment is multi server Dovecot/Exim running on FreeBSD servers, frontended by a layer3 load balancing switch and a NetApp NFSv3 datastore. The only real concern we have right now is race conditions and file write contention on the Dovecot index files. Our original plan was to use Dovecot LMTP on the servers to deliver to the inbox, but that doesn't seem to be recommended as we'll have a number of servers all acting as primary MX for domains and delivering to the same set of mailboxes. So are the Dovecot dotlock file locking mechanisms not enough for multiple servers trying to write/access index files in Maildirs? If we have to deliver straight to the ~/Maildir/new out of Exim, that's fine, also. We're just wondering if there is a added benefit of actually using LMTP. (other than making sure the index are kept the most recent). The other concern we have is client mailbox access. While we can make sessions "sticky" from one IP so they hit the same server, it doesn't help with the person that checks their email via POP from their PC while having their mobile phone access it via IMAP. (obviously from different IP addresses). So I guess there is some possibly index file write contention there as well. (though hopefully this should be rare). I'm curious as to know others experiences with a similar deployment. TIA -- Robert Blayzor INOC, LLC rblayzor(a)inoc.net http://www.inoc.net/~rblayzor/

[Dovecot] ACL with MySQL dict => full table scans
by Roland Rosenfeld 16 Jul '12

16 Jul '12

Hi! I'm just installing ACL support on 2.1.6. When a user changes these ACLs, this results in a full table scan on the dictionary, that tells dovecot who shares with whom. Here's what queries I see when I run $ doveadm acl delete -u user1 shared/user2/folder user=user1 1: SELECT dummy,to_user,from_user FROM imap_acl_shares 2: SELECT dummy,from_user FROM imap_acl_anyone 3: BEGIN 4: DELETE FROM imap_acl_shares WHERE to_user = 'user1' AND from_user = 'user1' 5: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user1','user1') ON DUPLICATE KEY UPDATE dummy='1' 6: DELETE FROM imap_acl_shares WHERE to_user = 'user2' AND from_user = 'user1' 7: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user2','user1') ON DUPLICATE KEY UPDATE dummy='1' 8: COMMIT Line 2 is okay, since imap_acl_anyone is always empty (I'm not able to disable this query, otherwise dovecot spawns errors about a missing map, but I can live with this). Don't ask me what lines 4/5 are repeated in 6/7, but these use indexes and I can live with this. But what the hell is line 1? Why doesn't dovecot use a WHERE clause here with either to_user='user1', to_user='user2', from_user='user1', or from_user='user2'? All these WHERE clauses would use an index and speedup the query. Without the WHERE clause I expect 100000 or more results on our production system, which could slow down it massively. Here's my setup: /etc/dovecot/dovecot-dict-sql.conf: connect = host=foo dbname=mail user=imap password=hidden map { pattern = shared/shared-boxes/user/$to/$from table = imap_acl_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = imap_acl_anyone value_field = dummy fields { from_user = $from } } And dovecot -n: # 2.1.6: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_cache_negative_ttl = 5 mins auth_cache_size = 100 M auth_cache_ttl = 5 mins auth_default_realm = example.com auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = always mail_gid = 999 mail_location = maildir:~/mail mail_plugins = acl quota mail_uid = 999 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave imapflags mmap_disable = yes namespace { list = children location = maildir:%%h/mail:INDEX=~/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/passwd.master driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/mail/sieve sieve_extensions = +imapflags } protocols = imap pop3 sieve service auth { unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0600 user = vmail } } service imap { process_limit = 4000 } service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 100 } service pop3 { process_limit = 1000 } shutdown_clients = no ssl = no syslog_facility = local2 userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 10 mail_plugins = quota imap_quota acl imap_acl } protocol pop3 { mail_plugins = quota pop3_no_flag_updates = yes pop3_uidl_format = %v.%u } Tschoeeee Roland

Hi Wojciech Thanks for your comeback.. > maybe - just as in article below > http://www.bishnet.net/tim/blog/tag/maildir-to-mbox/ > you like archive in such format I'm trying to switch dovecot to MBox, not just make archives. BTW: I use http://yergler.net/projects/one-off/maildir-to-mbox as it's much smaller and very simple to use to make archives. Does anyone else know the correct way to either switch the existing Maildir multiple file format to the single MBox file format. Failing that, though it will mean a LOT of work, how do I get dovecot to work in future in MBox single file format. I've entered 'mail_location = mbox:~/mail:INBOX=/%h/%u' in the 'dovecot.conf', but it still saves each message in a file of its own in the /new /cur /tmp directories ?? -------Original question -------- > Can someone guide me on changing the Maildir messages files > back to the single file format I used to have instead of the > dovecot.index /cur /tmp /new format my newer server currently > has.

[Dovecot] director: non standart ports at backends
by Костырев Александр Алексеевич 16 Jul '12

16 Jul '12

hello, I'm trying to figure out how to proxy pop3 and pop3s that listens on non-standart ports at backends. For example, pop3 is at 1110 and pop3s at 1995 (on backend side). is it possible? how should I separate this ports in director's config? it's easy for one port: for example lmtp - you just use passdb in protocol lmtp {}

[Dovecot] Issues with Plus addressing and detail part of subaddress.
by Sean Kamath 16 Jul '12

16 Jul '12

Hi all, So, it's been a while. I'm just ramping back up with Dovecot after a hiatus of a few years. I've been using it fine, complete with Sieve, for about a year, with little or no issues. I finally got around to setting up a second account, to start figuring out how I want to do some plus address filtering. In a nutshell, I want to put mail for foo+bar in foo's 'bar' folder. That's in the wiki. I did this: require ["fileinto", "envelope", "subaddress"]; if header :contains "subject" ["test"] { fileinto "Test"; } if envelope :detail "to" "test" { fileinto "test"; stop; } So, this fails miserably. No error message, nothing in the logs, no nothing. Yet, when I run sieve-test .dovecot.sieve /path/to/testmessage it works just fine. I even run sieve-test -e .dovecot.sieve /path/to/testmessage and it files it just fine into the folder. I tried adding some debug logging, but it looks like vnd.dovecot.debug isn't in my version. I searched the archives, and found a bit about adding (explicitly) the delimiter to the plugin section of 90-sieve.conf. So I did that. I'm running 2.0.13 of dovecot, and pigeonhole 0.2.3 on Solaris 10. Before I dive in and upgrade everything, am I missing something simple? The "test" bit works just fine (and in another account as well), so I think something's just not seeing the detail in subaddressing when mail is delivered (even though it works just fine with sieve-test). Thanks, Sean

[Dovecot] Migrating with dsync and INBOX.INBOX namespace issue
by Nikolai Schupbach 15 Jul '12

15 Jul '12

I'm working on migrating IMAP users from Mirapoint Message Servers to Dovecot servers. The Mirapoint IMAP server uses INBOX as a namespace for private mailboxes. I created the same namespace in Dovecot, but when I migrate mailboxes dsync seems to ignore/miss the namespace on Mirapoint and I end up with all mailboxes under a INBOX.INBOX hierarchy. Mirapoint Source Server ----------------------- * OK server.name Mirapoint IMAP4 3.8.3-GA server ready 1 LOGIN test(a)test.com test 1 OK User logged in 2 NAMESPACE * NAMESPACE (("INBOX." ".")) (("user." ".")) (("" ".")) 2 OK Completed 3 LIST "" * * LIST () "." "INBOX" * LIST () "." "INBOX.Draft" * LIST () "." "INBOX.Sent" * LIST () "."

Hello, More problems (it seems that we won't be able to put our new servers in production). The problem now is that when we reach 1000 dovecot processes we have errors like: Jul 9 12:10:22 myotis31 dovecot: imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument Jul 9 12:10:22 myotis31 dovecot: imap-login: Fatal: master: service(imap-login): child 32251 killed with signal 6 (core dumps disabled) and server doesn't accept any new connection. Our servers are running in ubuntu 12.04 with kernel 3.2.0-24-generic kernel. I have found a similar problem at https://bugzilla.redhat.com/show_bug.cgi?id=681578 but it is for redhat kernel of series 2.6. Could be the same problem?

First, this sub discussion in this thread has been dealing strictly with mechanical storage, and that was intentional. Now you've injected solid state storage, and in the process you first disagreed with my statement, then agreed with it. Apparently you didn't realize you did so. Would you please clarify what I stated that is "simply not true"? You comment WRT SSD doesn't prove anything I said to be untrue. Quite the contrary, you reinforced my statements. -- Stan

[Dovecot] recover .sieve plaintext from .sievec binary file
by Florin Andrei 10 Jul '12

10 Jul '12

Hi, I upgraded a server from an old Linux distribution to a much newer one. In the process, Dovecot got upgraded from v1 to v2. By mistake, I deleted the .sieve plaintext file with all the Sieve filters, but I still do have the .sievec compiled binary. Is there any way to dump the binary file back into plaintext format? Keep in mind, I'm running v2 now, and the binary was made on a v1 Dovecot server. Thanks. -- Florin Andrei http://florin.myip.org/

[Dovecot] mailboxes missing after upgrade from 2.1.4 to 2.1.7
by Micah Anderson 09 Jul '12

09 Jul '12

Hi all, I mentioned this on the #dovecot irc channel, but I thought I would post here so I can provide more details. The basic problem is that when I upgraded from 2.1.4 to 2.1.7, some users no longer are able to see their folders in pine/alpine. The folders are actually there, and are subscribed (according to doveadm) and its possible to do operations on those folders, if you know the name (for example, opening the folder works fine if you know the name). When I downgrade to 2.1.4 again, the folders appear again, so its clearly something that changed between the two versions. I looked through the changelog, and found a few possibile culprits, I think pine/alpine use imapc, so that could be related: . imapc: Use imapc_list_prefix also for listing subscriptions . Fixed looking up parent mailbox name with different namespace vs. layout separators. . imapc: Don't list mailboxes that don't match list patterns. . layout=fs: Fixed listing mailboxes with prefix=INBOX/ . LIST with mailbox {} settings incorrectly set subscribed-flags. Here is my dovecot -n output: # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_default_realm = example.net auth_verbose = yes default_process_limit = 256 default_vsz_limit = 512 M dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf quota = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 listen = * login_greeting = howdy, ready. mail_location = mdbox:~/mdbox:INDEX=/srv/dovecot_indexes/%d/%1n/%n mail_plugins = expire quota zlib stats maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . } namespace { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_allow_append_to_spam = yes antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /usr/local/bin/train_spam antispam_pipe_program_args = -d;10.0.1.109 antispam_pipe_program_notspam_arg = ham antispam_pipe_program_spam_arg = spam antispam_pipe_tmpdir = /var/tmp antispam_signature = X-Spam-Flag antispam_signature_missing = error antispam_spam_pattern_ignorecase = SPAM antispam_trash_pattern = trash;Trash;Deleted * expire = Trash expire2 = Trash/* expire3 = Spam expire_dict = proxy::expire quota = dict:Your mail quota::proxy::quota quota_rule = *:bytes=100663296 quota_rule2 = Trash:bytes=+20%% quota_rule3 = Spam:bytes=+10%% quota_rule4 = INBOX.Trash:bytes=+20%% quota_rule5 = INBOX.Spam:bytes=+10%% quota_rule6 = INBOX.restored_from_backups:bytes=+500%% sieve = ~/.dovecot.sieve sieve_after = /var/lib/dovecot/sieve/after.sieve sieve_before = /var/lib/dovecot/sieve/default.sieve sieve_dir = ~/sieve stats_refresh = 30 secs stats_track_cmds = yes zlib_save = gz zlib_save_level = 6 } postmaster_address = postmaster(a)example.net protocols = " imap pop3" service anvil { unix_listener anvil { group = dovecot mode = 0660 user = root } } service auth { unix_listener auth-userdb { group = mail mode = 0600 user = mail } } service dict { unix_listener dict { group = mail mode = 0600 user = mail } } service imap-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service imap-postlogin { executable = script-login /usr/local/sbin/postlogin_imap } service imap { executable = imap imap-postlogin process_limit = 2048 } service pop3-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service pop3-postlogin { executable = script-login /usr/local/sbin/postlogin_pop } service pop3 { executable = pop3 pop3-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = mail } } ssl_cert = </etc/certs/wildcard/cert.pem ssl_cipher_list = HIGH:-ADH:-aNULL ssl_key = </etc/certs/wildcard/key.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol lda { mail_plugins = expire quota zlib stats sieve plugin { quota_exceeded_message = Sorry, your message cannot be delivered to that person because their mailbox is full.

[Dovecot] + sub addressing setup
by Voytek Eymont 07 Jul '12

I have Dovecot/Postfix/MySQL/PostfixAdmin, I'd like to setup + sub addressing (for +spam and possibly user-defined +folders) I have setup a user+spam folder path in PostfixAdmin as so; vvv+spam@tld path:tld/vvv@tld/.spam/ that requires me to put a 'duplicate' user with the + and +path for each user, the folks on PostfixAdmin suggested that Dovecot might have a better way of handling this, how do I accomplish this in Dovecot ? thanks for any suggestions or tips -- Voytek

[Dovecot] Dovecot 2.1.8 crashes when doing POP3 UIDL on empty INBOX
by Joseph Tam 07 Jul '12

07 Jul '12

I noticed a bunch of crashes when Gmail users tried to slurp up their (empty) mailboxes. The problem is not noticed by clients though, but it crashes the pop3 process. POP3 session S: +OK Ready. C: USER user S: +OK C: PASS password S: +OK Logged in. C: UIDL ... server crash and disconnects ... Resulting log Jul 06 16:58:05 pop3(user): Panic: Trying to allocate 0 bytes Jul 06 16:58:05 pop3(user): Error: Raw backtrace: 0xff1e6454 -> 0xff1e4f78 -> 0xff20689c -> 0x18240 -> 0x1843c - > 0x185a0 -> 0x18a1c -> 0x1576c -> 0x159cc -> 0xff1fee6c -> 0xff200e24 -> 0xff1fef60 -> 0xff1d8010 -> 0x13584 - > 0x1285c Jul 06 16:58:14 pop3(user): Fatal: master: service(pop3): child 24972 killed with signal 6 (core dumps disabled) GDB traceback: #0 i_panic (format=0xff2302f8 "Trying to allocate %u bytes") at failures.c:259 #1 0xff2068a4 in pool_alloconly_malloc (pool=0x60330, size=0) at mempool-alloconly.c:259 #2 0x00018248 in client_uidls_save (client=0x54d28) at pop3-commands.c:761 #3 0x00018444 in cmd_uidl_init (client=0x54d28, seq=0) at pop3-commands.c:793 #4 0x000185a8 in cmd_uidl (client=0x54d28, args=0x19eb8 "") at pop3-commands.c:824 #5 0x00018a24 in client_command_execute (client=0x54d28, name=0x2b550 "UIDL", args=0x19eb8 "") at pop3-commands.c:889 #6 0x00015774 in client_handle_input (client=0x54d28) at pop3-client.c:629 #7 0x000159d4 in client_input (client=0x54d28) at pop3-client.c:682 #8 0xff1fee74 in io_loop_call_io (io=0x37298) at ioloop.c:379 #9 0xff200e2c in io_loop_handler_run (ioloop=0x34138) at ioloop-poll.c:211 #10 0xff1fef68 in io_loop_run (ioloop=0x34138) at ioloop.c:398 #11 0xff1d8018 in master_service_run (service=0x33c88, callback=0x13120 <client_connected>) at master-service.c:543 #12 0x0001358c in main (argc=1, argv=0xffbffe0c) at main.c:268 Some non-trivial changes in pop3-commands.c were done between 2.1.3 and 2.1.8 (expecially pop3_uidl_duplicates changes in 2.1.7). I guess this bug has crept in there. Joseph Tam <jtam.home(a)gmail.com>
