Hi all there - sorry I have to repeat the mail since I got the message it was not delivered correctly. Hi all, I have run successfully a postfix/dovecot installation some time ago.

[Dovecot] doveadm backup issue with ACL plugin enabled
by Thomas Leuxner 05 Jan '13

Hi, when trying to backup mailboxes I noticed some hiccups when the ACL plugin is enabled. It works fine with ACL disabled: $ doveadm -o plugin/quota= backup -u tlx(a)leuxner.net mdbox:/home/backups/tlx/mdbox However, enabled (and w/ a mailbox actually using ACLs) the following error occurs: $ doveadm -o plugin/quota= backup -u tlx(a)leuxner.net mdbox:/home/backups/tlx/mdbox dsync(tlx(a)leuxner.net): Error: Couldn't update mailbox <name> metadata: Permission denied I tried to override the ACL plugin via '-o' to no avail, but I may be using the wrong syntax there.

Hello, I'm trying to investigate a problem with dovecot/imap dumping core when connecting connecting mith mutt (everything else works). imap(user@domain): Fatal: master: service(imap): child 31752 killed with signal 11 (core dumped) I managed to create a core file and passed that to gdb.

[Dovecot] Non-standard fields?
by Attila Nagy 04 Jan '13

04 Jan '13

Hi, Non-standard fields are mentioned here: http://wiki2.dovecot.org/MailboxFormat/Maildir and they are stated as currently not used. Questions: - am I right that if they will be used, they will be key=value pairs, like fields in the base filename? Like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,X=12,A=something - or are they supposed to be flags, like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,ABCD - are there any plans to utilize these? Thanks,

[Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 04 Jan '13

04 Jan '13

I'm trying to get Dovecot working with Virtual Users and Sendmail on OpenIndiana 151a7. OpenIndiana is the Open Source continuation of OpenSolaris after Oracle tried to kill it off a couple of years ago shortly after acquiring Sun Microsystems. I'm not sure if this is so much a Dovecot problem, as much of a Sendmail problem. I thought this would probably be a better list to start with, though. If not, please let me know. I initially used this Dovecot wiki page to approach this: Simple Virtual User Installation http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I had to make few minor changes, but I don't think anything significant to the problem I'm having. I can log into SquirrelMail with both virtual users, and with system users. I can send mail to system users from both virtual and system users. I can see the mail that I sent in the Sent Messages folder for both types of users. I just can't send mail to virtual users. When I try to, I get the following message: ERROR: Message not sent. Server replied: Requested action not taken: mailbox unavailable 550 5.1.1 <dswebstore@localhost>... User unknown My configuration info is as follows: systemuser@openindiana:~# /usr/local/sbin/dovecot --version 2.1.12 systemuser@openindiana:~# /usr/local/sbin/dovecot -n # 2.1.12: /usr/local/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 101 info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = mbox:/home/vmail/%u/mail:INBOX=/var/mail/%u passdb { args = /usr/local/etc/dovecot/passwd driver = passwd-file } pop3_uidl_format = %g protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } ssl = no userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { postmaster_address = systemuser@localhost } --- My dovecot password file looks something like this, though changed for obvious security reasons: systemuser:{PLAIN} systemuserPASS virtualuser1:{PLAIN}virtualuser1PASS virtualuser2:{PLAIN}virtualuser2PASS --- I read on this page that I needed to put the following in my sendmail dovecot.m4 file: Dovecot LDA with Sendmail http://wiki2.dovecot.org/LDA/Sendmail So this is my dovecot.m4 file, which shows up in my sendmail.cf file after recompiling my sendmail.mc file. ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u --- Finally, this is my sendmail.mc file: divert(-1) # # Copyright (c) 1983 Eric P.

[Dovecot] clucene-config.h location
by Dimitri 04 Jan '13

04 Jan '13

By deafult, CLucene installs the clucene-config.h header to /usr/lib/CLucene, but fts-lucene tries to include it from /usr/include/CLucene and fails. Here is how it is fixed in Fedora, for instance: sed -i '/DEFAULT_INCLUDES *=/s|$| '"$(pkg-config --cflags libclucene-core)|" src/plugins/fts-lucene/Makefile.in Indeed, Lucene's pkgconfig file reflects the fact that some headers reside in /usr/lib/CLucene. It would be great if Dovecot used pkgconfig for CLucene. Thanks, Dimitri Mageia Linux packager

[Dovecot] Can't rename mailboxes, any ideas on how to fix?
by Howard Leadmon 04 Jan '13

04 Jan '13

I am running Dovecot 2.1.12 under FreeBSD, and I use Outlook 2010 with imap to connect to my server. I know I used to be able to rename mailboxes, as I do this every year at year end, but when I went to rename some mailboxes the start of this year, blamo up popped the message "CANNOT Renaming not supported across conflicting directory permissions". Then only thing that has really been updated here, is Dovecot itself, as I know the FBSD port updates when new versions are released. Any clues on what may have caused this, or how to best correct it? --- Howard Leadmon

[Dovecot] Dovecot 1.2.7 and Roundcube LIST-EXTENDED commands
by aristidis fesarlis 04 Jan '13

04 Jan '13

Hi all, we use Dovecot 1.2.7 with Maildir, and recently we have set up the latest Roundcube webmail. Inside its config file,it is mentioned that: // By default list of subscribed folders is determined using LIST-EXTENDED // extension if available. Some servers (dovecot 1.x) returns wrong results // for shared namespaces in this case. http://trac.roundcube.net/ticket/1486225 // Enable this option to force LSUB command usage instead. I notice that it seems to work fine, though. We don't have shared namespaces. So my question is: should I change it to LSUB, or will I have problems with my Maildir subscriptions? Thanks

[Dovecot] Folder names
by James Starowitz 04 Jan '13

04 Jan '13

Running a pretty basic setup of imap +pop3 on version 2.1.10 Users are able to create folders in imap that contain "&" the folder on the backend reflects "&-" as it should, you can list folder, but then when you relog into imap then decides it can no longer subscribe to this folder due to invalid UTF characters. Essentially allowing users to lock themselves out by using a very common character in a folder name. Might one of the imap client compatibility plugins in imapd cause this quirkiness ? Should I be coming at this from another direction? Is this a bug?

[Dovecot] Kerberos/GSSAPI auth via .k5login file
by Jörg Herzinger 04 Jan '13

04 Jan '13

Hi, we are currently moving our mailserver to a new server with Dovecot, virtual users in LDAP, Passwords in Kerberos Setup. Everything works fine except for GSSAPI which seems to be a bit buggy. The thing is, that when using a .k5login [1] file it seems that SASL does not get passed the home directory specified userdb. In other words, mails for user1 (see below) are stored in /home/domain.at/user1, while the home dir defined in LDAP is /afs/domain.at/home/user1 (virtual users, so only dovecot, not the system does know about this user and home dir). If I do create a .k5login file in /home/domain.at/user1 with the content "someotheruser(a)DOMAIN.AT", then someotheruser should be able to authenticate himself as user1 via GSSAPI. However, this .k5login file is completely ignored. So it seems to me that the home is not passed on to SASL. If I do add ldap to my nsswitch (for testing only) I additionally have real system users. Now if I create a .k5login in their home defined in LDAP which now also the system knows about everything works just fine. It is still the wrong home since its the one in LDAP and not the one defined by dovecot but at least it shows that our setup is working.

[Dovecot] dovecot and avahi
by Robert Moskowitz 03 Jan '13

03 Jan '13

I am trying to figure out if I need avahi on my mail server. I see that POP3 and IMAP are services that Avahi can advertise/discover. Does Dovecot work with Avahi and how do you get POP3 and IMAP advertised? And perhaps more importantly, what clients look for mail services this way? I can't find any information on this in the Dovecot documentation ot googling. Perhaps my search fu is low this year. thank you

[Dovecot] Migration Problem UW-IMAP to Dovecot Maildir
by Michael Sloan 03 Jan '13

03 Jan '13

I've just replaced our ancient (10-year old) mail server running Sendmail/UW-IMAP on Solaris with Postfix/Dovecot 2.1.10 running on Linux on new hardware. I opted to go with virtual users and I didn't want to create system accounts and I might end up hosting another department's mail as well. We have a mix of POP3 and IMAP users, roughly 90 total. The POP3 user mailboxes migrated without a hitch, and the IMAP user mailboxes (in what looks like mbox format) migrated well for the INBOX (found in /var/mail/<username> ) but for those few who managed to create local folders and had mail files in their home directories, those mail files were ignored. Is there any clean way to manage to migrate those folders to the new server now? There were no .mailboxlist or .subscription files anywhere on the old mail server. When I was planning the migration, I tried a variety of the methods listed on the UW-IMAP and generic migration pages including dsync, uw2dovecot.pl, and several others. What appeared to work well at the time was this, although I still have the mail in users' home directories to recover/migrate: /usr/local/bin/doveadm -o imapc_user=$1 -o pop3c_user=$1 -o imapc_password=$2 -o pop3c_password=$2 backup -R -u $1(a)caps.fsu.edu imapc: with this dovecot.conf: # 2.1.10: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.0.13-0.27-pae i686 SUSE Linux Enterprise Server 11 (i586) ext3 auth_mechanisms = plain login disable_plaintext_auth = no imapc_features = rfc822.size imapc_host = p1.caps.fsu.edu imapc_list_prefix = INBOX listen = * mail_location = maildir:/var/vmail/%d/%n/Maildir namespace { hidden = yes list = no location = pop3c: prefix = POP3-MIGRATION-NS/ } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { pop3_migration_mailbox = POP3-MIGRATION-NS/INBOX } pop3_uidl_format = %08Xv%08Xu pop3c_host = p1.caps.fsu.edu service auth { unix_listener /var/run/dovecot/auth-master { mode = 0600 user = vmail } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = postmaster_address = postmaster(a)caps.fsu.edu } protocol doveadm { mail_plugins = " pop3_migration" } -- Michael Sloan Systems Administrator FSU Center for Advanced Power Systems sloan(a)caps.fsu.edu

[Dovecot] How To Remove?
by Christian Guastella 03 Jan '13

03 Jan '13

hi, i was looking to setup imap on an old PPC G5 mac i have running as webserver and gateway/firewall machine.. found a dovecot-2.1.7-0.pkg online, and it looked like the typical easy install thing.. someplace called rudix made the package.. not much there in way of instructions, but after i finally figured out where the executable had been stuck i tried it, just to see what kinda config errors would be thrown-up.. got the line below.. /usr/local/sbin/dovecot: Bad CPU type in executable so i'm guessing this means dovecot is intel-cpu only? i don't have the time or patience to read all the unix junk, and get a compiler, do all the make files etc.. been years since i did any of that, and don't want to do it again.. the pkg installer did not come with an uninstaller, and since the install is pretty much useless, is there some list of what it installed so i can get rid of it all? thanks, christian

Re: [Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 01 Jan '13

01 Jan '13

Well our situation is kind of like this: We've been using UW-Imap for 12-15 years, and have loved it. It has a beauty and simplicity to it that is simply wonderful. We're located in a remote part of the Rocky Mountains, and the only internet connection we can get that's faster than a dial-up is a satellite. Lousy upload speeds. Can't host our own sites here. We've been hosting our sites on one of our parishioner's servers for years; but through the years, that's become more and more problematic, and we'd like to do more with it than we currently can. We'd like to set up our own server at our guest house in town. I wanted to use OpenIndiana (Solaris) to take advantage of some of the really amazing features it has. So, I set up UW-Imap on it. Works great. Glory be to our holy God. The problem is, after I got all that working, I went to set up the users for it, and discovered the GUI for creating the users won't allow me to add any users with usernames longer than eight characters. I'm not real dependent on GUI's, and a quick search on the net told me that I can easily add the users with the long user names from the command line. So, I asked on the UW-Imap and on the OpenIndiana list for people's experience about this. Two people said they'd been using long user names on Solaris and BSD for years without any problems, while two others recommended changing to an IMAP server that supports virtual users. One of those recommended Dovecot. So I started looking at Dovecot. I'm not real keen on Sendmail, but to make matters worse, we host our own email on our server here in the mountains. Since we can't get reverse DNS set up for our satellite connection, we have to relay our emails through our parishioner's server, which does have reverse DNS, or else most people's email servers reject them as spam. We also need to be able to send and receive emails from multiple domains. So, I have to be able to figure out how to do both parts of the relay -- our part where we tell our MTA to relay it through the other host, and what will become the server at our guest house to accept those emails and relay them on to the recipients. And the multiple domain issue. I can do all this with UW-Imap and Sendmail, because we've already done all the fighting necessary to get it to work. We've been doing it for years. It just leaves us with the question of whether it's better to go with using UW-Imap on a system that's not designed to support long user names, and possibly getting bit by that, or whether it's better to fight it out trying to learn all this other stuff with a different IMAP server and MTA? Fun! I could probably get Cyrus IMAP to work with Sendmail, because I tried it briefly years ago and already have gone through the grief of figuring that out. But I didn't particularly care for it. One of the things I like most about UW-Imap -- and Dovecot shares this -- is that it's easy to backup, restore inadvertently deleted directories, and to move emails from one server to another. From what I remember, Cyrus wasn't so friendly about that. And it was more difficult to administer than UW-Imap and Dovecot. After reading the 13-page article Ken posted this afternoon, I started looking at Postfix. My impression is, that maybe this might be a good route to try. Dovecot - PostFix - and if I'm going to go through all that, I might as well go with Sieve, instead of Procmail, like we've been using for years. I used Sieve briefly with Cyrus. I've never been thrilled with Procmail. So, with all that background, if anyone would like to share any suggestions or advice, I would certainly appreciate it.

[Dovecot] dovecot crashing?
by Eric 30 Dec '12

30 Dec '12

Happy holidays! I am experiencing an issue when trying to check my mail using IMAP. with Dovecot I have tried checking my mail using a full GUI client (Thunderbird) and telnet. Both times I get disconnected before all of my messages can be downloaded and I see an error in my mail log. Here are the details: [root@cust19-1-prod-domain userqa]# dovecot --version 2.0.9 [root@cust19-1-prod-domain userqa]# dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 CentOS release 5.4 (Final) disable_plaintext_auth = no login_trusted_networks = 172.19.136.0 mail_location = maildir:~/Maildir mail_max_userip_connections = 100 mbox_write_locks = fcntl mmap_disable = yes passdb { args = scheme=plain username_format=%n /etc/dovecot/users driver = passwd-file } protocols = imap ssl = no userdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } [root@cust19-1-prod-domain userqa]# i try to check my mail: username@ops1-1-domain:~$ telnet cust19-1-prod-domain imap Trying 172.19.136.223...

The attachment seems small in size: Content-Disposition: attachment; filename="report_amex.xlsx"; size=20527; That means the attachment is 20527 bytes, correct?

Postfix doesn't allow external hosts to connect & relay mail, which explains what you're seeing. Why you're seeing that is better addressed on the postfix list, although you seem to have told postfix to use Dovecot for sasl auth, so maybe, since this is the Dovecot list you should send your Dovecot conf so we can see why it's not working. Also, if you ask on the postfix list you will be asked for the out-put of postfinger which can diagnose sasl problems. Simon

[Dovecot] Update 1.2 -> 2.0 ... INBOX away?
by Martin Rabl 29 Dec '12

29 Dec '12

Hi, yesterday I did an update from dovecot 1.2 to 2.0.19 (Ubuntu 10.04 -> 12.04). After fixing the configuration dovecot startups as it should, but with one error, I don't understand: the INBOX will not be delivered to the Mailclient and will not be filled by "deliver". Instead, dovecot create the two dirs "new" and "cur" directly in "Maildir". the filesystem looks now like: domain/user1/Maildir/INBOX # official INBOX domain/user1/Maildir/new # new mail domain/user1/Maildir/cur # read mail We have searched for an configuration error, but didn't found anything - or did not see one ;-) Maybe there is someone in the list, which see our error in a moment? We are using only imap/s and managesieve, no pop3. Maildir-Layout is FS. Here a snippet of our configuration: ------------ mail_home = mail_location = maildir:~/Maildir:LAYOUT=fs namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/Maildir/:INDEX=%%h/Maildir/shared/%u:LAYOUT=fs prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = yes location = maildir:/srv/vmail/public:LAYOUT=fs prefix = public/ separator = / subscriptions = no type = public } protocol lda { mail_plugins = sieve autocreate } protocol imap { imap_client_workarounds = delay-newmail tb-lsub-flags tb-lsub-flags mail_max_userip_connections = 10 mail_plugins = acl autocreate imap_acl } ------------ Hope you can help! Thank you! Martin

[Dovecot] question
by mattk＠kraner.us 29 Dec '12

29 Dec '12

I just install Dovecot and postfix. When I'm pull dovecot I see in the log that its checking for mail. if a put a test message locally on the server I can pull the message down to my cell phone and other computers. But when I try to a message from gmail or aol it doesn't come in to the server. it always bounces back to the place were I sent it from

[Dovecot] mdbox: more then one altstorage
by Peer Heinlein 29 Dec '12

29 Dec '12

The mdbox-format with the altstorage-feature is quite nice and important. But we're having much more then >> 30 TB of maildata and doing an fsck on huge partitions takes too much (down-) time for our mailsystem. It would be much easier, if Dovecot would be able to use at least THREE storage-paths for his m-Files (and not just TWO like now). Having an altstorage1 and altstorage2, we would be able to move away all mails from on altstorage-mountpoint, we could put this storage-moungpoint into "maintenance" and do an fsck without Downtime for Dovecot. It would be nice having a doveadm-feature to put a altstorage-path in "maintenance-mode", so to move easily away all m-files to other alt-storage-paths and to let Dovecot know not to use this locked partition. Having even more then 3 storage-paths would be nice for huge setups: In this case we could easily use different SMALLER partitions without having just two or three huge partitions > 15 TB. The architecture of the altstorage-system is nice and simple. Wouldn't it be easily possible to look (at least) in three, then just in two places for a m-file? What about a "hash_dir"-system for the storage? What about a configuration-parameter like altstorage_dirs=4 which would mean, that there are 4 storage-mountpoints that could be addressed by "%m": mail_location = mdbox:/vmail/%d/%n/mdbox:altstorage/alt/%m/%d/%n In this case, Dovecot could easily use all existing partitions automatically "round-robin". Or maybe it would be better to tell Dovecot the partitions by: altstorage_dirs_existing = 1,2,3,4 altstorage_dirs_newmail = 1,4 so it would be very easy to tell Dovecot in which partitions he has to look for m-files and where he is allowed to save round-robin new e-mails. With this setup it's easy to put a partition in maintenance mode.

[Dovecot] dovecot 2.1.12 panic in mbox-sync.c

Hello! I use dovecot 2.1.12 locally on a 32bit Linux with an ext4 filesystem and after deleting a lot of emails from a mbox folder, I now get the following messages in the log: dovecot: imap(amied): Panic: file mbox-sync.c: line 1351 (mbox_sync_handle_eof_updates): assertion failed: (offset == 0 || offset > 31) dovecot: imap(amied): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4559a) [0x6f68959a] -> /usr/lib/dovecot/libdovecot.so.0(+0x45611) [0x6f689611] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x6f658fa0] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x2d707) [0x6f708707] -> /usr/lib/dovecot/libdovecot-storage.so.0(mbox_sync+0x53) [0x6f7091d3] -> /usr/lib/dovecot/libdovecot-storage.so.0(mbox_storage_sync_init+0x6d) [0x6f70936d] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x3b) [0x6f72333b] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync+0x3f) [0x6f72347f] -> dovecot/imap(cmd_select_full+0x16b) [0x805529b] -> dovecot/imap(cmd_select+0x17) [0x8055c57] -> dovecot/imap(command_exec+0x32) [0x80596f2] -> dovecot/imap() [0x80586fd] -> dovecot/imap() [0x805880d] -> dovecot/imap(client_handle_input+0x125) [0x8058a05] -> dovecot/imap(client_input+0x60) [0x80592f0] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x44) [0x6f6981f4] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xce) [0x6f6991ce] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x6f697cd0] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x2e) [0x6f680dbe] -> dovecot/imap(main+0x279) [0x804fdd9] -> /lib/libc.so.6(__libc_start_main+0xf5) [0x6f49bad5] -> dovecot/imap() [0x804ff51] The mbox file seems to be unchanged and a .lock file remains even after stopping dovecot.

[Dovecot] dovecot testinstallation does not tell how to quit
by Robert Moskowitz 28 Dec '12

28 Dec '12

I am having problems logging in with RoundCube, so thought I should see if there were instructions for testing Dovecot login, and sure enough I found some at: wiki.dovecot.org/Testinstallation Well it works, so the problem is probably all RoundCube's, but this wiki page is missing an important line about how to end the Telnet session without killing Telnet! What is the quit/exit command? And please add this to the wiki! Oh, I just guessed it: a logout

[Dovecot] Using -module flag on sieve libs
by Dimitri 26 Dec '12

26 Dec '12

Some modern distros (Mageia, Mandriva) use -no-undefined as a default linker flag for building software. However, undefined symbols are OK if the binary being linked is a plugin. To detect plugins, build system looks for presence of "-module" libtool flag in makefiles. There are two libraries in Pigeonhole that couldn't be linked with -no-undefined: src/lib-sieve/plugins/mailbox/libsieve_ext_mailbox.la src/lib-sieve/libdovecot-sieve.la These modules do contain undefined symbols, but they are not linked against library that provides them. It would be good if corresponding makefiles contained "-module" flags, so that build system could selectively turn off that -no-undefined linker flag. Please see proposed patch (attached). Thanks, Dimitri Mageia Linux packager

[Dovecot] Postfix/mysql/dovecot - Understanding password encryption
by Robert Moskowitz 25 Dec '12

25 Dec '12

I am switching from a fedora/postfix/mysql/couriermail/squirrelmail to Centos/.../dovecot/roundcubemail and adding postfixadmin to the mix. My tutorial before was an earlier version (on F14) of: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-my… Now I am using http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMai… to get me started. I am up to roundcubemail setup and am stumbling to understand what the author here is doing with encrypted passwords, so felt it was time to delve deeper into this. My old setup uses mysql-crypt for the password. MYSQL_CRYPT_PWFIELD password and users could be added to the table with: INSERT INTO `users` (`email`, `password`, `quota`) VALUES ('sales(a)example.com', ENCRYPT('secret'), 10485760); But where this was all simple and no choices, I get to figure out what to do with my dovecot setup. Some of the 'secret' is hinted at in postfixadmin's config.inc.php: // Encrypt // In what way do you want the passwords to be crypted? // md5crypt = internal postfix admin md5 // md5 = md5 sum of the password // system = whatever you have set as your PHP system default // cleartext = clear text passwords (ouch!) // mysql_encrypt = useful for PAM integration // authlib = support for courier-authlib style passwords // dovecot:CRYPT-METHOD = use dovecotpw -s 'CRYPT-METHOD'. Example: dovecot:CRAM-MD5 $CONF['encrypt'] = 'md5crypt'; Where is there information on the different choices and how to choose. Is it as 'simple' as setting up postfixadmin to control the password encryption format then 'inform' dovecot in the dovecot-mysql.conf with default_pass_scheme = MD5-CRYPT Thank you for any pointers.

[Dovecot] Understanding Sockets
by Tim Smith 22 Dec '12

22 Dec '12

Hi, Just trying to consolidate my knowledge of Dovecot and I want to understand various things rather than just key out lines of config in dovecot.conf with the hope of it working. What I wanted to clarify is my understanding the "socket listen" section of the config file. From my limited understanding, this section details how other processes can access the userdb defined in Dovecot. The master socket is used for "internal" processes which is mainly dovecot-lda so that when Dovecot receives mail it knows where to deliver it and client is defined for "external" processes, for example Postfix who would use the info to determine if a user existed. Would you say this is a fair (albeit) dumbed down!!) synopsis of sockets and their purpose? Thanks in advance! Tim

[Dovecot] Non-dovecot user looking for feedback
by Chris Ross 21 Dec '12

21 Dec '12

I've been using UW-IMAPd for neigh on forever (at least since 2001). But, as it's basically stalled, and I'm about to update the hardware that is my mail server, I thought it was time to review existing open-source IMAP servers. Dovecot is the top three in my looking. The other of the top three candidates, because I know of people who've used it, is Cyrus IMAP. So, I should note that my thoughts are "uw-imapd, because I already know how to use it", "Cyrus, because someone I know/trust liked it years ago", and dovecot, because "it seems stable, professional, and to meet all of my needs". I guess the biggest question I have is how files/folders are stored in the filesystem. uw-imapd has a "mbx" format that all of my folders are in, and also has support for mbox and maildir (i think). mbx had some advantages for speed access, which would be unimportant I assume with dovecot's indexes, but IIRC there was also some reason the mbox format coped poorly with multiple clients accessing the same folder at the same time. So, am I right that dovecot supports only the "one big full file" mbox format, and the maildir format? And if so, is it known to allow multiple simultaneous IMAP clients to access and monitor and/or modify the same folder simultaneously? After those questions, it's just a "what do you think the pros and cons of each are?" I know asking in this forum, that I will get most if not all votes for Dovecot. And that's fine, as long as you have specific reasons why it would be better for someone with only a handful of users and minimal time available to administer the systems in question. Thanks! I appreciate any and all feedback. - Chris

[Dovecot] backtrace from postgres dict
by Steffen Kaiser 20 Dec '12

20 Dec '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since I enabled ACLs I get following backtrace. It looks like that it happens if the ACLs had been changed only. Also, it looks like that it always happens 1 minute after last "dict: Info: pgsql(localhost): Connected to database dovecot", no matter if the user is logged in (and idle) or logged off. Postgres logs: "could not receive data from client: Connection reset by peer" and "unexpected EOF on client connection". Is there some TCP keep alive issue? Postgres is using the "system default" for TCP keep alive. I'm currently testing ACLs via telnet, so the activity with the ACL dict is pretty low, hence, an idle timeout would make much sense. # ../../sbin/dovecot --version 2.1.10 (a4f02f6c0d32) dict connect string: connect = host=localhost dbname=db user=user 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:58 IMAP(user) [22922]: Info: Disconnected: Logged out in=23 out=763 2012-11-28 10:04:41 dict: Panic: file driver-pgsql.c: line 84 (driver_pgsql_set_state): assertion failed: (state == SQL_DB_STATE_BUSY || db->cur_result == NULL) 2012-11-28 10:04:41 dict: Error: Raw backtrace: /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x4857a) [0x7f91f511157a] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x485c6) [0x7f91f51115c6] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f91f50e4eaf] -> dovecot2.1/dict() [0x40aa36] -> dovecot2.1/dict() [0x40aa91] -> dovecot2.1/dict() [0x40bed3] -> dovecot2.1/dict() [0x409504] - -> dovecot2.1/dict(sql_db_cache_deinit+0x20) [0x408a60] -> dovecot2.1/dict(main+0x169) [0x405a59] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f91f4b5cc8d] -> dovecot2.1/dict() [0x404bb9] 2012-11-28 10:04:41 dict: Fatal: master: service(dict): child 22923 killed with signal 6 (core not dumped) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBULXbiGoxLS8a3A9mAQI9Ywf/YItPO4fFT70HcuwCkDXgx0Sn7CEyXu2j +1VzOu3R/TMs1rcxYJIvWiei6Nk3wXywzQl84POadJn61Yf2NuT80nMxwBsBbgio e+0oRE9JNVSjtvX5l7kehEdUDQjqRRKyrhWG9KDlpjWidGsYh7pQg0rDtp3UwG57 HuSBMiBAZ9t9sC2DXjn9wT9vweH3gMIhc/K5U0BLF5JG/K8UAKc5QBUgezjIYzvn KP90TJ4RoZ2vnPzmWfeIsjffRBvvC6UUgWmU02e2H9xJxzF32Nix0s8YWi7G91sH Ei057HW5NsKNDtp6B5fYk+xCpC6ucQiwFSr/ZG+uZCAdtTd2qmf60g== =tQYK -----END PGP SIGNATURE-----

[Dovecot] setting mail_home and vacation
by Andreas Meyer 20 Dec '12

20 Dec '12

Hello! dovecot version 2.1.7 I set up vacation with sieve. We have mboxes and maildirs and in dovecot.conf mail_location = mbox:/var/spool/vhosts/%d/dovecotprivate/%n:INBOX=/var/spool/vhosts/%d/%n Error: User archiv(a)xyz.de doesn't have home dir set, disabling duplicate database Dec 19 20:37:03 lda(archiv(a)xyz.de): Error: sieve: sieve script file path ~/.dovecot.sieve is relative to home directory, but home directory is not available. Dec 19 20:37:03 lda(archiv(a)xyz.de): Error: sieve: failed to access user's sieve script ~/.dovecot.sieve (using default script location instead) When I set mail_home = mbox:/var/spool/vhosts/%d/%n:INBOX=/var/spool/vhosts/%d/%n I get this for mboxes in the log: Error: user archiv(a)xyz.de: Relative home directory paths not supported: mbox:/var/spool/vhosts/xyz.de/archiv:INBOX=/var/spool/vhosts/xyz.de/archiv The .dovecot.sieve script of the user seems to be found, a vacation response is sent and the email is stored mail into mailbox 'INBOX' What is wrong?

[Dovecot] Problems trying to add dspam delivery to dovecot LDA to working Postfix/Dovecot server. No passdb.
by Brian Jarrett 20 Dec '12

20 Dec '12

Hello list, I'm really hoping someone can point me in the right direction on this. I set up a server using Postfix with LDAP lookups to Active Directory. Postfix delivers to maildir. Dovecot IMAP and POP are working correctly using PAM Kerberos to authenticate via Active Directory. I want to add spam filtering, so I'm trying to set up Postfix to use dspam which is then supposed to use Dovecot LDA to deliver messages to the mailbox instead of having Postfix deliver to the Maildir. I can't get any deliveries to Dovecot LDA to get past passdb lookup. When I run /usr/lib/dovecot/deliver -f bjarrett(a)garfield16.org -d bjarrett(a)metcalfexcavation.com I get: Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master in: USER#0111# 011bjarrett(a)metcalfexcavation.com#011service=lda Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: password( bjarrett(a)metcalfexcavation.com) passdb doesn't support credential lookups Dec 19 20:57:55 mxserver2 dovecot: auth: Error: static( bjarrett(a)metcalfexcavation.com) passdb doesn't support lookups, can't verify user's existence Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master out: FAIL#0111 Dec 19 20:57:55 mxserver2 dovecot: lda: Error: user bjarrett(a)metcalfexcavation.com: Auth USER lookup failed Dec 19 20:57:55 mxserver2 dovecot: lda: Fatal: Internal error occurred.

[Dovecot] Maildir hardlinks with sieve
by Benedetto Vassallo 19 Dec '12

19 Dec '12

Hi all, First of all, excuse me for my previous posts (Maildir hardlinks). Today I realized the following issue. Maildir hardlinks works OK on dovecot 2.1.10 without sieve. If set sieve plugin in dovecot-lmtp hardlinks stop working. Is there a way to have both sieve and hardlinks working?

[Dovecot] namespace subscription problem
by Holger Hegmanns 19 Dec '12

19 Dec '12

Hi all, my problem seems to be a cosmetic one (again). According to the docs: subscriptions: "yes" (default) if this namespace should handle its own subscriptions. If "no", then the first parent namespace with subscriptions=yes will handle it. Therefore is no way to create the following scenario: three namespaces (private, shared, public) the private namespace has to handle its own subscriptions the private namespace setup with "prefix = INBOX." the both shared and public namespace setup with "subscriptions = no" cause there is no so called "parent" namespace. Private namespace setup with "prefix = " works fine, but that's not what I want. namespace { type = public separator = . prefix = public. location = maildir:/var/spool/dovecot/vmail/public subscriptions = no } namespace inbox { type = private separator = . prefix = INBOX. inbox = yes } namespace { type = shared separator = . prefix = user.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } Any chance that the private namespace can subscribe to shared mailboxes with the principals above? ... Few hours later. Added a default namespace without any prefix: namespace { prefix = separator = . hidden = yes subscriptions = yes } Subscriptions works as expected, but when I telnet to dovecot now the LSUB command shows all boxes beneath the INBOX as well as without the prefix: b lsub "" * * LSUB () "." "Sent" * LSUB () "." "Templates" * LSUB () "." "Trash" * LSUB () "." "Drafts" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Templates" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Drafts" * LSUB () "." "INBOX.user.bar.Sent" * LSUB () "." "user.bar.Sent" b OK Lsub completed. Completely stuck Holgert

[Dovecot] migration to dovecot pop3
by Rajesh M 19 Dec '12

19 Dec '12

hi i am planning to migrate from qmail pop3 to dovecot pop3 the number of users on the server is large over 5000 also data volume is large - over 3.5 tb -- ie many users several 1000s of emails in their inbox email clients used are outlook / outlook express / windows mail, etc my questions 1) will the migration cause all the emails on the server to re-download 2) can dovecot be configured to allow only one download at a time - pop3 locking with time out setting that can be customized 3) can dovecot pop3 be configured so that it will allow download of emails only of the last say 15 days ie even if the same pop3 user is configure on another machine it will download only messages of the last 15 days 4) has anybody migrated from qmail pop3 to dovecot pop3 successfully without emails being downloaded again thankyou very much in advance rajesh
