How to obtain a "non-stripped" executable for producing a usable core-dump
by Ben Johnson 14 Sep '16

14 Sep '16

Hello, I'm attempting to capture a core-dump file, and gdb reports warning: core file may not match specified executable file. And only after installing "dovecot-dbg" on my system (Ubuntu 16.04 LTS) does gdb report further warning: the debug information found in "/lib64/ld-2.23.so" does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch). It took some searching the internet to realize that both messages are likely the result of having a "stripped" executable: # file /usr/lib/dovecot/dovecot-lda /usr/lib/dovecot/dovecot-lda: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=49c9c607c304a5c853c05a4ccb9e4b995f185ac4, stripped So, how best I am I to obtain a "non-stripped" dovecot-lda executable? Must I forego my distro's repositories and download the dovecot source, compiling every executable and all plugins "from scratch", in order to obtain a useful core-dump file? Perhaps the bug report instructions at http://www.dovecot.org/bugreport.html should mention "stripped" executables and how to avoid them. Perhaps I am simply ignorant, but if that is the case, there is little to no hope for the "average user" where submitting bug reports is concerned. Any guidance would be most appreciated. Thanks in advance, -Ben

Limit replication to one user
by Arne Hoffmann 14 Sep '16

14 Sep '16

Hello, we have a setup here where the main (and only important) feature of the IMAP server is the public folder. Two Dovecot instances are running in a active/passive cluster and mailstorage should be replicated between the two. Since there is a race condition when using public namespaces (locking on user level and not on mailbox level) I had the intention of limiting the replication to one user. I read somewhere that dsync is replicating all the users the command "doveadm user '*'" shows. And the command only shows *one* user because I have modified the iterate_query: ,----[/etc/dovecot/mysql.conf] | iterate_query = SELECT username AS user FROM mailbox WHERE username = 'data_replication(a)example.com' `---- root [~]# doveadm user '*' data_replication(a)example.com root [~]# So, why does Dovecot still replicate mails from other users inboxes? And why does doveadm replicator still show other users? root [~]# doveadm replicator status '*' username priority fast sync full sync success sync failed data_replication(a)example.com none 00:57:14 01:13:21 00:57:12 - arne.hoffmann(a)example.com none 00:20:04 00:31:40 00:20:02 - root [~]# [I removed some whitespace to keep line length in check] Any explanation of this behavior would be just awesome.

Dovecot con Autentication Checkpassword error signal 111
by zerocool＠modemsoft.it 13 Sep '16

Good morning, It is the first time I write in this mailing list and I apologize in advance for possible nonsense that i can write. I have a mail server with qmail + courier imap and I would "Migrate" to dovecot. I installed the package and configured the components necessary to me using as system autentication checkpassword. I have verified the checkpassword operation without the processor usage of Dovecot and is functioning. When you perform the tests with dovecot from the logs out these errors: auth: Error: checkpassword(plutos,127.0.0.1,<WLcLPkg8esF/AAAB>): Child 15375 died with signal 11 auth: Error: checkpassword(plutos,127.0.0.1,<WLcLPkg8esF/AAAB>): Child 15376 died with signal 11 imap-login: Info: Disconnected (auth failed, 2 attempts in 8 secs): user=<plutos>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured master: Warning: Killed with signal 15 (by pid=15479 uid=0 code=kill) or : auth: Error: checkpassword(plutos,192.168.1.113,<zzV561I8IuDAqAFx>): Child 15851 died with signal 11 auth: Error: checkpassword(plutos,192.168.1.113,<zzV561I8IuDAqAFx>): Child 15852 died with signal 11 imap-login: Info: Disconnected (auth failed, 2 attempts in 8 secs): user=<plutos>, method=PLAIN, rip=192.168.1.113, lip=192.168.1.113, secured imap-login: Info: Disconnected: Too many invalid commands (no auth attempts in 102 secs): user=<>, rip=192.168.1.235, lip=192.168.1.113 auth: Error: checkpassword(plutos,192.168.1.235,<7pLd+FI81uXAqAHr>): Child 15870 died with signal 11 It is already a long time that we slam but I can not figure out where to make the mistake.

Re: Use of obox2 and AWS S3

Thanks Karol My challenge with AWS EFS is waiting for it to be HIPAA/BAA certified. But good to know it's a satisfactory option.

As the initial performance is bad it scales pretty quickly with space used. So it handles maildir storage very well. The latency is a little high but with indexes there is no problem. It works as NFS storage with unlimited space (8EB) and you pay for what you use. So it turns out to be very cost effective as you do not have to worry about reserving space. For better performance you can keep indexes on ephermal storage or EBS, which both have much lower access times. As for 'elastic cloud type hosting' EFS store can be used by thousands of instances in multiple AWS AZs at the same time, so it looks like it is somehow optimized.

Sieve filtering SPAM and redirect
by Andre Luiz Paiz 12 Sep '16

12 Sep '16

Hi every body. I'm having difficulties to setup my filters correctly and I really need some help. This is my environment: Mail that is received on the system passes through a sieve_before script that checks the message header for SPAM tag and store it into the "Junk" folder. If no spam tag is found, mail goes to inbox. My horde webmail is integrated with sieve, so this allow users to create their own scripts to store mail in other folders or forward them to external accounts. And this are the problems I'm having: 1 - When users create a forward filter to redirect to external mail, mail that is stored inside the Junk folder are not forwarded; 2 - If I insert a "keep" parameter inside the sieve_before script to keep processing the rules, the mail is forwarded, but becomes duplicated and stored inside the inbox or other folders, if the user has more filters. 3 - If I move my sieve_before script to sieve_after, the same thing happened, one copy is stored on the user selected folder (inbox or filtered), including mail marked as SPAM. My needs are: I need to separate SPAM and HAM e-mail before users intervention (so I need sieve_before). But this SPAM e-mail has to be forwarded if a forward filter is created. Is it possible to use a sieve_after script that moves (instead of copy) the user mail marked as SPAM to the Junk folder even if it was stored in a different folder? Is that possible? Thanks a lot.

Use of obox2 and AWS S3
by Raymond Sellars 11 Sep '16

11 Sep '16

Hi Has anyone used or is using dovecot obox and S3 storage? I see very little chatter or documentation on it. Interested in how mature it is and technical items such as high availability and region replication. I'm guessing that multiple updates to a S3 mailbox is mitigated via the standard dovecot pattern of Director pointing multiple user sessions to a single/common dovecot node. And for disaster recovery - that's out of scope of dovecot and more reliant on S3 replication? Any one running a dovecot solution within AWS in general? Interested in best practice for the storage layer. Although NFS is possible its not really optimised for elastic cloud type hosting. Thanks Raymond

sieve - find in header
by Hajo Locke 09 Sep '16

09 Sep '16

Hello list, have a problem with sieve script. I want to perform an action if an arbitrary headerline contains a defined string. I tried with regex: if header :regex [".*"] ["searchstri.*"] { fileinto "junk"; } This is not working because regex is only used in 2nd argument ["searchstri.*"] In 1st argument [".*"] no regex is used, sieve expects just plain string. Something like this would work, if "x-myheader" contains "searchstring": if header :regex ["x-myheader"] ["searchstri.*"].... How to solve this case and find a string in arbitrary/unknown headerline? Thanks, Hajo

OK, the origin of your problem becomes clearer. You can hardcode these paths into the executables by doing something like env CFLAGS='-I/my'ssl/include' \ LDFLAGS='-L/your/ssl/lib -Wl,-rpath,/my/ssl/lib' \ configure ... I use this myself (except the -Wl part since these libs are symlinked to my shared library path). I think "-R/my/ssl/lib" might also be synonymous with -Wl,... > Dovecot is the only package I know of where there are like a thousand > places to put additional libs in the Makefile.am files, but most of > them are totally ignored by configure. I don't have that problem -- I use configure to tell dovecot where to find my self-compiled openssl, and the resulting executables load from where I want. Joseph Tam <jtam.home(a)gmail.com>

doveadm quota recalc returns a Segmentation fault
by Alessio Cecchi 07 Sep '16

07 Sep '16

Hi, with the latest dovecot-ee version (2.2.25.4 (5cb7c97)) if I run “doveadm quota recalc -u alessio(a)skye.xn--it-02t dovecot return a “Segmentation fault” (but the quota is update fine). Since dovecot version 2.2.24.3 (55cdc32) works fine. This is my quota backends configuration: plugin { quota = maildir:UserQuota quota2 = dict:Quota Usage::noenforcing:proxy::sqlquota } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } I found that if I comment the line “quota2 = dict:…” doveadm quota recalc works fine. I have two quota backends because with dict I can store everybody's current quota usage in a SQL database for fast retrieving (like quota_clone plugin but I cannot switch to it immediately).

You can also affect where shared libraries are loaded using the LD_LIBRARY_PATH environment variable.

It's fine for a temporary working around problems (like this one, so you're absolutely right :-) However, no program should require that for regular use because you never know exactly if somebody in the chain of executed code removes certain environment variables. And also the opposite way, if Dovecot runs external programs, those might not play well with an existing LD_LIBARY_PATH and incompatible SSL libraries. For every program I compile myself, I link it against my custom OpenSSL library (always newest version; distributions usually tend to stick with a specific version and only apply security fixes). For most packages (eg, Exim, Apache HTTP, BIND, INN, OpenSSH, Mutt, wget etc.) it pretty straightforward. Even if not, usually I can find a quick solution myself. Dovecot is the only package I know of where there are like a thousand places to put additional libs in the Makefile.am files, but most of them are totally ignored by configure. And even if I modify the Makefile files after configure, again most of the additional options get ignored. Never seen it that complicated. As Dovecot is my favorite IMAP daemon, there's no way I'm giving up. :-) I'm totally confident that the developers will find a good solution. And I'm happy to test every patch they come up with. Greetings, Andreas

Cannot subscribe to Public mailbox
by MI 04 Sep '16

04 Sep '16

I'm trying to set up a Public mailbox, but when I try to subscribe to it in Thunderbird, nothing happens: it doesn't appear as a folder, and when I go back to the Subscribe window, it is unchecked again. I use postfix local dlivery, which created a Maildir when a mail arrived for this mailbox: /home/others/sharedmail/Maildir/{cur,new,tmp} (sharedmail is a system user so that Postfix can deliver the mail; it doesn't have a login shell or a password) To make sure it is not a simple filesystem permissions problem, I did "chmod -R a+rwX Maildir/" This is my current config ( I tried to keep it short by leaving only what might be relevant ): # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.9 ... mail_location = maildir:~/Maildir namespace { list = yes location = maildir:/home/others/sharedmail/Maildir prefix = Public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox ... ... } prefix = separator = . } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } userdb { driver = passwd } Also, I'm not sure about the difference between type=public and type=shared. But anyway, I tried both with the same result.

Alternate mail store of few users is disparaged unexpectedly
by Prakash Autade 02 Sep '16

02 Sep '16

Hello, We are using dovecot with mdbox and ALT store on S3(Simple Storage System). We export the mail_location=mdbox:/<user-mailstore>/mdbox:ALT=/altmailstore/<user-mailstore>/mdbox of user in extra parameters. Today, alternate mail store of few users is disparaged unexpectedly which resulted in mail loss. We are unable to trace out why and when the alternate store is disparaged. Our hypothesis is, the folder is removed during doveadm altmove. We want to prevent this in future. It will be great if someone helps to identify the root cause. Dovecot version: 2.2.19 # dovecot -n # 2.2.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-573.el6.x86_64 x86_64 CentOS Linux release 6.0 (Final) auth_mechanisms = plain login auth_verbose_passwords = plain disable_plaintext_auth = no mail_fsync = always mail_gid = 65111 mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" mail_uid = 65111 mdbox_rotate_interval = 1 days mdbox_rotate_size = 20 M mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { auto = create } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = create special_use = \Trash } mailbox chat { auto = create } prefix = INBOX. separator = . type = private } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } ssl_cert = </conf/server/server.crt ssl_key = </conf/server/server.key -- Sincerely, Prakash P.

Dovecot 2.2.25 fails on SSL
by Andreas M. Kirchwitz 02 Sep '16

02 Sep '16

Dear Dovecot developers! This problem already existed some years ago, has been fixed, and now it's there again in Dovecot 2.2.25 (2.2.24 was fine). I'm running CentOS 6 with a custom OpenSSL installation in /usr/local/ssl Therefore, Dovecot is configured like this: env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/Dovecot-2.2.25 --with-ssl=openssl --with-ssldir=/usr/local/Dovecot-2.2.25/etc/dovecot/certs With "pkg-config", the same options for SSL are provided.

Force SSL/TLS and client certificate checking only for connections from Internet
by Konstantin Khomoutov 02 Sep '16

02 Sep '16

(Please CC me if possible.) I have Dovecot 2.2.13 (shipped with Debian 8 "Jessie") serving IMAP for a small organization. It's connected both to the Internet and to that organization LAN. I'd like to have Dovecot has rather tight security requirements for connections made from the Internet and reasonably laxed requirements for the LAN clients. Due to Dovecot authenticating users against a LDAP database which is also used for logging into the users' machines, we have to use somewhat weak passwords (randomly generated but short) for most users. Because of this I want to: * Mandate the usage of TLS for the connections made from Internet; * Require the clients to present their SSL certificates, and * Verify the validity of these certificates. The certificates are issued by our own CA, so it's not a problem to verify them. The first iteration was to set ssl = required and disable_plaintext_auth = yes which I then overrode with a "remote" section for LAN connections: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes } The next iteration was to actually enable verification of the client certificates. I have set the "ssl_ca" variable appropriately, then ssl_require_crl = yes ssl_verify_client_cert = yes and auth_ssl_require_client_cert = yes Then I went on and attempted to override the latter two settings for the LAN clients by appending them to my special "remote" section to it read: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes ssl_verify_client_cert = no auth_ssl_require_client_cert = no } But after restart Dovecot complained that I cannot use the "auth_ssl_require_client_cert" setting in a "remote" section. I have removed it in the hope that still having ssl_verify_client_cert = no there would inhibit SSL certificate checks for the LAN clients but apparently it did not. So, to recap: * I need to have tight TLS settings for the clients connecting from the Internet: - TLS is required; - The client must present a valid certificate (issued by a CA we control). * LAN clients should use relaxed security settings: TLS is okay but that's all. How do I go about setting this? (On a side note, I can supposedly get away installing stunnel and making it proxy IMAP and IMAPS connections to Dovecot -- at least from the documentation, it appears stunnel supports IMAP+STARTTLS, -- but I would rather have all this handled solely by Dovecot.)

Debian Jessie comes with systemd so you really should not use initscript anymore but switch to systemd for starting dovecot. There is systemd service description file available for you in case your vendor does not provide it in the package: https://github.com/dovecot/core/blob/master/dovecot.service.in Sami
