Dovecot Pro Community Edition
by Markus Petzsch 28 Sep '16

28 Sep '16

Hi, I'm trying to setup push notifications for Open-Xchange (OX) and struggle with finding the push_notification plugin. According to https://oxpedia.org/wiki/index.php?title=AppSuite:OX_Mail#Requirements it should be found in the Dovecot Pro Community Edition. I'm currently running dovecot that came with CentOS 7.2 but am intrested in OX's push feature. Can someone point me in the right direction where to find the community edition repos? https://oxpedia.org/wiki/index.php?title=Dovecot:Main_Page_Dovecot#dovecotq… only lists password protected repos. Thx for your help in advance. Best Regards Markus Petzsch

Trying to regain access to my email archive after an upgrade.
by Rick Jones 27 Sep '16

27 Sep '16

Hi - I had been running an Ubuntu 12.04 system on which I receive email, with an inbox in /var/mail/ and a bunch of folders under ~/Maildir. When I upgraded from 14.04 there were a bunch of questions about keeping old/new config files and my muddling through it has me seeing only the inbox, and then a Drafts, Sent and Trash Folder. I would like to regain access to the messages stored under ~/Maildir, but have been thoroughly unsuccessful. I seem to run into duplicate prefix issues and I suspect I have other issues, when I try to add: namespace rest { separator = / prefix = location = maildir:~/Maildir } to what is already present. I've seen a few of the wiki pages, but not fully understanding what is going-on I'm afraid I've not groked them terribly well. any help/pointers for this cluser would be much appreciated. rick jones raj@tardy:~$ dovecot --version 2.2.9 raj@tardy:~$ dovecot -n # 2.2.9: /etc/dovecot/dovecot.conf doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:25: 'imaps' protocol is no longer necessary, remove it doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:732: protocol managesieve {} has been replaced by protocol sieve { } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:904: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:942: passdb pam {} has been replaced by passdb { driver=pam } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:1055: userdb passwd {} has been replaced by userdb { driver=passwd } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:1117: auth_user has been replaced by service auth { user } # OS: Linux 3.13.0-95-generic x86_64 Ubuntu 14.04.5 LTS auth_mechanisms = plain login log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail 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 = } passdb { driver = pam } passdb { driver = pam } protocols = imap service auth { user = root } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } raj@tardy:~$ vi /etc/dovecot/conf.d/15-mailboxes.conf raj@tardy:~$ dovecot --version 2.2.9

imapc fetch optimization
by Nagy, Attila 27 Sep '16

27 Sep '16

Hi, imapc does a lot of UID FETCH $UID (BODY.PEEK[]), which is nice, because it works even with the dumbest IMAP server, altough it really kills performance, especially on high latency lines. I wonder: if IMAP servers can effectively handle boundless fetches (like a list with all wanted UIDs, or simply 1:* if all are needed), do you see this as a good addition to develop? This could be a new imapc_features setting afterall... Thanks,

Drac Plugin
by Darryl Baker 27 Sep '16

27 Sep '16

I now have the drac plugin compiled and working. The plugin binary might even work with the Debian/Ubuntu binary. It was a one line change. I need to talk to the sendmail folks about their macro for the DRAC feature. My custom sendmail.cf code works in a way that makes using drac and SpamHaus for anyone on a blacklisted IP such as non-comercial Comcast users. I am hoping that the drac plugin will get fixed in the core distribution and possible the new binary make it into the Debian/Ubuntu binary build. *** dovecot-2.2.22/src/plugins/drac/drac-plugin.c 2016-09-23 22:49:56.345568783 -0500 --- dovecot-2.2.22/src/plugins/drac/drac-plugin.c-orig 2016-09-26 14:33:46.828670909 -0500 *************** *** 25,31 **** /* libdrac function */ int dracauth(char *, unsigned long, char **); ! const char *drac_plugin_version = DOVECOT_ABI_VERSION; static struct timeout *to_drac = NULL; static const char *drachost = NULL; /* dracd host */ --- 25,31 ---- /* libdrac function */ int dracauth(char *, unsigned long, char **); ! const char *drac_plugin_version = DOVECOT_VERSION; static struct timeout *to_drac = NULL; static const char *drachost = NULL; /* dracd host */ *Darryl Baker*

Shared mailboxes nightmare (for me :-( )
by Felix Rubio Dalmau 27 Sep '16

27 Sep '16

Hi everybody, I am honestly desperate: I have spent/invested the whole day in trying to set a shared mailbox, with quite partial success. The INBOX is merged with the top level mailbox, and there are many more folders. To give an idea, for the shared account sharedacc(a)domain.org, this is how looks the folder structure: sharedacc |-folderA |-folderB \-folderC in the account for usera(a)domain.org, I see the following: usera |-folderD |-folderE |-folderF \-shared \-sharedacc So, I do not get to see folderA, folderB, folderC, etc. My configuration is: # 2.2.25 (7be1766): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.14 (099a97c) # OS: Linux 4.5.4-0 x86_64 Debian stretch/sid zfs mail_plugins = zlib expire acl plugin { acl = vfile acl_shared_dict = proxy::acl } dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } namespace { list = children location = mdbox:/mnt/vmail/%%d/%%n:INDEXPVT=/mnt/vmail/indexes/shared/%%d/%%n prefix = shared/%%n/ separator = / subscriptions = yes type = shared } protocol lmtp { mail_plugins = zlib expire acl sieve } protocol imap { mail_plugins = zlib expire acl antispam imap_acl } the files I have one the account for sharedacc are: sharedacc |-dovecot-acl |-dovecot-acl-list \-mailboxes |-dovecot-acl |-folderA | \-dbox-Mails | \-dovecot-acl |-folderB | \-dbox-Mails | \-dovecot-acl \-folderC \-dbox-Mails \-dovecot-acl In dovecot-acl-list I have the following contents: 1474920778 folderA 1474920778 folderB 1474920778 folderC and in every dovecot-acl, I have: user=usera(a)domain.org akxeilprwts All the files on the filesystem are owned by the same vmail user. What is strange is that I can see all these folderA, folderB, folderC in roundcube, and I can click to subscribe to them. However, when I go back to the general view, the subscriptions have been reset and I see only sharedacc, without a thing inside. Finally, in kmail I can see the subscribed folders without a problem (??!) Can please somebody help me?

Setting hostdomain
by Arie Peterson 25 Sep '16

25 Sep '16

Hi all, Preparing for a replication setup, I read (at the bottom of <http://wiki2.dovecot.org/Replication>) that `dovecot --hostdomain` should give a different output on the two servers. This is not the case for me: both give "localhost". I'm trying to change my configuration to set the hostdomain to another value, but I can't find how to do this. I tried: • setting the environment variable DOVECOT_HOSTDOMAIN=mydomain in /etc/default/dovecot (which is read by the init script); • adding the line import_environment = TZ DOVECOT_HOSTDOMAIN=mydomain to dovecot.conf; • the combination of both of the above. However, after restarting dovecot none of these changes seem to have any effect: `dovecot --hostdomain` still returns "localhost". This is with dovecot version 2.2.13. How should one change this setting? Thanks, Arie

configure fail if libssl is named libssl-opt
by A. Schulze 25 Sep '16

25 Sep '16

Hello, I try to build dovecot with my own version of openssl. It's compiled in a way the libraries can coexist without symbol conflict with the real OpenSSL in /usr: They are named libssl-opt and libcrypto-opt. Now configure fail to find my libssl-opt: CFLAGS="..." CXXFLAGS="..." CPPFLAGS="..." LDFLAGS="..." SSL_LIBS='-lssl-opt -lcrypto-opt' ./configure ... --with-ssl=openssl ... checking for SSL_read in -lssl... no configure: error: Can't build with OpenSSL: libssl not found Is there an other way to tell configure the ssl libraries have other names?

Try this: Create a directory and do the following in that directory. Create the file openssl.cnf with the following information: [ req ] default_md = sha2 distinguished_name = req_distinguished_name [ req_distinguished_name ] countryName = US localityName = Boulder organizationName = Your orginizations name here organizationalUnitName = IT Department emailAddress = some email address at your company commonName = "Just a simple statement about the company" [ certauth ] subjectKeyIdentifier = hash authorityKeyIdentifier = keyid:always,issuer:always basicConstraints = CA:true [ client ] basicConstraints = critical,CA:FALSE keyUsage = digitalSignature, keyEncipherment, dataEncipherment extendedKeyUsage = clientAuth Just change the things you need to for you. Then issue the following command. openssl req -config ./openssl.cnf -newkey rsa:2048 -nodes -keyform PEM -keyout dovecot.key -x509 - days 365 -extensions certauth -outform PEM -out dovecot.pem -subj "/C=US/postalCode=00000/ST=state/L=city/streetAddress=some street/O=company name/OU=IT Department/CN=dovecort cert/emailAddress=email(a)yourcompany.com" Just change the C, O, OU, etc for your needs. Then verify the contents via: openssl x509 -noout -in dovecot.pem -subject openssl x509 -noout -in dovecot.pem -issuer openssl x509 -noout -in dovecot.pem -enddate openssl x509 -noout -in dovecot.pem -text This will show what is in the certificate. Now copy the pem & key files to where you want them. Restart dovecot. You may have to change the configuration to use the names just created.

Director keeping IMAP connections alive
by Webert de Souza Lima 23 Sep '16

23 Sep '16

Hello, I have a 2 director - 2 dovecot set up in a cluster. >From time to time I notice high usage of RAM by dovecot process, and analyzing with doveadm who, I see many users with dozens, even hundreds of PIDs. Inspecting those PIDs I see each one of them is an IMAP connection, coming from either director process, and ESTABILISHED. A deeper analysis shows me that there ltos of connections from the same users to BOTH dovecot instances, but as I am using director, this shouldn't happen, right? Ok. The thing is, one of the dovecot instances have only old connections (like 3 days old) and the other dovecot have some old and some newer connections. So, director is redirecting recent connections to the right dovecot, as expected, but it is keeping many of old and unused connections open, consuming resources. output of doveconf -n from dovecot: http://pastebin.com/trMEjeAs output of doveconf -n from director: http://pastebin.com/EUpHYMKY Thanks.

Broken auth-* sockets.

Hello. I am migrating my servers to Ubuntu and have been having an issue with Dovecot authenticator service. Exim is set up to use dovecot-auth, anticipating the question whether exim binary was compiled with support of Dovecot authenticator, it was: --- # exim -bV Exim version 4.86_2 #1 built 05-Apr-2016 12:21:41 Copyright (c) University of Cambridge, 1995 - 2015 (c) The Exim Maintainers and contributors in ACKNOWLEDGMENTS file, 2007 - 2015 Berkeley DB: Berkeley DB 5.3.28: (September 9, 2013) Support for: crypteq iconv() IPv6 PAM Perl Expand_dlfunc GnuTLS move_frozen_messages Content_Scanning DKIM Old_Demime DNSSEC PRDR OCSP Lookups (built-in): lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmjz dbmnz dnsdb dsearch ldap ldapdn ldapm mysql nis nis0 passwd pgsql sqlite Authenticators: cram_md5 cyrus_sasl dovecot plaintext spa tls Routers: accept dnslookup ipliteral iplookup manualroute queryprogram redirect Transports: appendfile/maildir/mailstore/mbx autoreply lmtp pipe smtp Fixed never_users: 0 Size of off_t: 8 Configuration file is /etc/exim4/exim4.conf --- The problem is sockets Dovecot creates are somehow broken. Exim reports something like: --- 2016-09-21 14:45:26 dovecot_plain authenticator failed for *** ([***]) [***]: 435 Unable to authenticate at present: authentication socket connection error 2016-09-21 14:45:26 dovecot_login authenticator failed for *** ([***]) [***]: 435 Unable to authenticate at present: authentication socket connection error --- and I initially thought it was wrong permissions for the socket, triple checked and they are 100% right. More than that, I temporarily chmodded it "rw" for the world as follows: --- # ls -l /var/dovecot/auth-* srw-rw-rw- 1 Debian-exim root 0 Aug 17 21:20 /var/dovecot/auth-client srw------- 1 dovecot root 0 Aug 17 21:20 /var/dovecot/auth-login srw-rw-rw- 1 Debian-exim root 0 Aug 17 21:20 /var/dovecot/auth-master -rw------- 1 root root 32 Aug 15 19:35 /var/dovecot/auth-token-secret.dat srw-rw-rw- 1 dovecot root 0 Aug 17 21:20 /var/dovecot/auth-userdb srw------- 1 dovecot root 0 Aug 17 21:20 /var/dovecot/auth-worker --- and Exim reports the same problem.

Logging of custom mail headers
by Francesco Fiore 22 Sep '16

22 Sep '16

Hi, I need to configure Dovecot to log some custom mail headers. I red the documentation of the mail_log plugin but I didn't found which field I've to use as value for mail_log_fields parameter. So, I red the plugin code but in mail-log-plugin.c there're defined only "from" and "subject" fields that match some email header. I found three alternatives: 1. use the mail_filter plugin (spawning a new process, ecc.) 2. coding a new plugin using the notify plugin 3. propose a patch to the mail_log plugin that use a new configuration parameter (es. mail_log_headers) and log the specified mail headers Which is the better solution for you? Thanks in advance Francesco

dsync-server: Configure lock-file location?
by Udo Waechter 21 Sep '16

21 Sep '16

Good day everyone, I have a situation where my mail-folder structure (mdbox) ist like this: My users have the following data: $ doveadm user XYZ(a)xx.com field value home /srv/mail/ mail mdbox:foo/XYZ@xx.com/ I also do replication between 2 nodes. Now, I sometimes (when a lot of replication is happening I get the following errors: dovecot: dsync-local(XYZ(a)xx.com): Error: Couldn't lock /srv/mail//.dovecot-sync.lock: Timed out after 60 seconds This of course not only for XYZ(a)xx.com It seems to me, that my mailbox structure should rather be: $ doveadm user XYZ(a)xx.com field value home /srv/mail/foo mail mdbox:XYZ@xx.com/ in order to get rid of these messages? Unfortunatly I cannot change that. I've searched around and took a look into the code of dsync-server, unfortunatly the path to the lockfile is not configurable. Is there a way to somehow configure the lock-file location for dsync-server? Thanks very much, udo.

The reason is that dovecot rebinds to anonymous bind after succesful auth bind instead of rebinding to external sasl bind.

by David Williams 20 Sep '16

20 Sep '16

Hi there I'm having problems getting sieve to send a second vacation response. For testing I've set sieve_vacation_min_period = 500s and the seconds option in the script is 600. I send the first test message and get a reply fine I then wait about 12 minutes send a second message and get no reply. In the log I get "discarded duplicate response". I've restarted dovecot and removed the .dovecot.lda-dupes file before running the last test. I'm using LMTP for delivery to Dovecot. The sieve script is require ["vacation-seconds"]; # rule:[Vacation] if true { vacation :seconds 600 :addresses "username(a)mydomain.com" :subject "vacation" "test"; } and doveconf -n is # 2.2.19: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.9 (357ac0a0e68b+) # OS: Linux 3.18.12-gentoo x86_64 Gentoo Base System release 2.2 ext4 auth_username_format = %Ln disable_plaintext_auth = no imap_capability = +XLIST mail_location = maildir:/srv/mail/%n/Maildir 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 index ihave duplicate vacation-seconds imapflags notify namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox "Sent Items" { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = } passdb { args = * driver = pam } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /var/lib/dovecot/sieve/default.sieve sieve_default = /var/lib/dovecot/sieve/default.sieve sieve_extensions = +notify +imapflags +vacation-seconds sieve_vacation_default_period = 1d sieve_vacation_min_period = 500s sieve_vacation_use_original_recipient = yes } postmaster_address = postmaster(a)mydomain.com protocols = imap lmtp sieve service auth { unix_listener auth-userdb { group = mode = 0777 user = } } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 10024 } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key submission_host = localhost userdb { driver = passwd override_fields = home=/srv/mail/%n } protocol lmtp { mail_plugins = sieve } protocol lda { mail_plugins = sieve } I've changed the identifying info to stop any spammers.

Dovecot and imapproxy

imapproxy sped things up a lot for me when I was using courier. I switched to dovecot a while back and kept using imapproxy. Lately I've been noticing weird TCP Queuing spikes in my munin graphs and discontinuing my use of imapproxy seems to have smoothed them out completely and I haven't noticed a slowdown in webmail. Is imapproxy generally not necessary with dovecot? - Grant

Panic: file auth-request.c
by Chris Wik 19 Sep '16

19 Sep '16

Hello Dovecot list, We've been running a really old CentOS 5 server with the stock dovecot from yum (1.0.7) for years and years with absolutely no problems. If it ain't broke, don't fix it, or something like that. Well it finally broke, but only due to the server no longer being able to handle the load of the increasing user base (many thousands now, with hundreds of concurrent IMAP connections any any given time) So we upgraded to a new CentOS 7 server with SSD RAID, fast CPUs and tons of RAM. No more load problems. We compiled the latest dovecot from source (as the version from CentOS yum repo is already quite old, figure we might as well run the latest version since we were upgrading anyway). Thanks to excellent documentation on dovecot.org and fairly thorough testing, the upgrade was quite smooth. We kept all the message UUIDs intact and tried to match the supported authentication methods etc to the old setup, and we didn't have any problems with clients re-downloading or re-syncing mail. We do however have one problem, which prompted me to join this list. It is the same problem as described in this thread from last month: http://dovecot.org/list/dovecot/2016-July/104899.html Here's the excerpt from our maillog: Sep 17 19:34:57 mail dovecot: auth: Panic: file auth-request.c: line 1049 (auth_request_lookup_credentials): assertion failed: (request->credentials_scheme == scheme) Sep 17 19:34:57 mail dovecot: auth: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x89470) [0x7fa9cb8af470] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x8954e) [0x7fa9cb8af54e] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fa9cb851f75] -> dovecot/auth() [0x4165bc] -> dovecot/auth() [0x4221fb] -> dovecot/auth() [0x41620b] -> dovecot/auth(auth_request_lookup_credentials_callback+0x58) [0x4162f8] -> dovecot/auth(passdb_handle_credentials+0x6a) [0x4254ba] -> dovecot/auth() [0x425b62] -> dovecot/auth() [0x41c1f8] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x4c) [0x7fa9cb8c207c] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xd7) [0x7fa9cb8c3377] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x7fa9cb8c2105] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fa9cb8c22b8] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fa9cb857f33] -> dovecot/auth(main+0x2eb) [0x40ccdb] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7fa9c9dc2b15] -> dovecot/auth() [0x40cf15] On the client side, it manifests as an authentication failure, and the user is prompted to re-enter their password. The reports we've had are all from users who have their passwords saved in a local password manager, so the client is definitely sending the correct password. It's not related to a particular mail client. It is also definitely not related to the particular user or password, as the user will authenticate many times successfully and then (seemingly) randomly be hit by this bug and prompted to re-enter their password. We enabled verbose logging and even logging of passwords for failed authentication attempts in an attempt to find a pattern, but so far we have not found one. Similar to the original poster in the above thread, we are using a MySQL backend, and CentOS 7 on x86_64 It happens quite frequently: in the past 6 days it happened 49175 times, according to a grep of the maillog. In the same period there were 294167 successful IMAP logins and 160322 POP3 logins. For now we have downgraded to 2.2.4 and so far have not seen the crash recorded in the maillog. What can we do to help track down and fix this bug? # dovecot -n # 2.2.24 (a82c823): /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.0-327.28.3.el7.x86_64 x86_64 CentOS Linux release 7.2.1511 (Core) ext4 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login digest-md5 cram-md5 ntlm rpa apop auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /var/log/dovecot-debug.log default_client_limit = 5000 default_process_limit = 1000 disable_plaintext_auth = no first_valid_uid = 89 mail_debug = yes mail_fsync = never mail_gid = 89 mail_location = maildir:/var/virtual/%d/%n mail_uid = 89 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 = } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } pop3_client_workarounds = outlook-no-nuls oe-ns-eoh service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_ca = <*** ssl_cert = <*** ssl_key = <*** userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_ssl = yes protocol lmtp { mail_fsync = optimized } protocol lda { mail_fsync = optimized } protocol imap { mail_max_userip_connections = 50 } protocol pop3 { mail_max_userip_connections = 20 } -- Chris Wik Anu Internet Services www.anu.net | www.cwik.ch

Hi, I'm currently debugging replication issues and I found that both servers answer to a "dovecot --hostdomain" simply with localhost From what I've read, this can lead to problems. Where do I configure the dovecot hostdomain name? The machine itself has a valid name in /etc/hostname Thanks, Thomas

Yes, exactly, that's my usual approach. I've used this as well for building other software with custom libraries. Unfortunately, I remember CFLAGS/LDFLAGS didn't play well with Dovecot, so I used SSL_CFLAGS/SSL_LIBS as suggested by the documentation and that worked well. > 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,... Based on your mail I've tried CFLAGS/LDFLAGS again, and now Dovecot didn't even compile any longer. I was close to giving up. But obviously, I didn't ... :-) After some investigation I found the non-default linker option "-Wl,--as-needed" as problem which is enabled by Dovecot for unknown reasons. Finally, this call to "configure" generates proper Makefile files to build Dovecot with a custom SSL library: env CPPFLAGS="-I/usr/local/ssl/include" LDFLAGS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib" LIBS="-Wl,--no-as-needed -lcrypto -lssl" SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -Wl,--no-as-needed -lcrypto -lssl" ./configure --prefix=/usr/local/dovecot --with-ssl=openssl (chances are that SSL_CFLAGS/SSL_LIBS could be removed completely but it won't hurt) I've read the section in the "ld" manual but still don't understand why Dovecot enables --as-needed (never seen that before with other software) and why it's such a big problem. But I'm no expert here. > 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. Thanks for pointing me at the proper direction again. Now Dovecot 2.2.25 compiles for me with a custom SSL. I understand that this issue might not have a high priority but maybe one of the developers could check if "--as-needed" is really needed (as it confuses people who try to use custom libraries) and what's the deeper meaning of SSL_CFLAGS/SSL_LIBS. My system is a regular CentOS 6 (latest sub-release with all patches), nothing special except for a custom SSL installation. Greetings, Andreas

converting maildir to mailbox
by Anton Yuzhaninov 16 Sep '16

16 Sep '16

Hi all! There is a script to convert maildir to mailbox in wiki: http://wiki.dovecot.org/Migration/MailFormat but it doesn't convert any message flags (seen e.t.c.). I wrote a script, which converts most flags and labels: https://bitbucket.org/citrin/scripts/src/tip/dovecot-maildir2mbox.pl It doesn't convert recent flag and UIDs though, because it was not necessary in my case. Do you think link to the script should be added to dovecot wiki? -- WBR, Anton Yuzhaninov P. S. My use case was: get maildir from other server, convert to mbox, compress (gzip -9) and add to my mailbox as read-only archive.

Hi, Looks like something has been committed to master-2.2 in the last week which is causing crashes as soon as the remote user logs in: Sep 17 01:11:19 thunderstorm.reub.net dovecot: dsync-server(reuben): Error: read(lightning.reub.net) failed: EOF (last sent=mailbox_state, last recv=mail (EOL)) Sep 17 01:11:31 thunderstorm.reub.net dovecot: imap(reuben): Panic: file fts-api.c: line 128 (fts_backend_set_cur_mailbox): assertion failed: (ctx->cur_box != NULL) Sep 17 01:11:31 thunderstorm.reub.net dovecot: imap(reuben): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0xb7f9f) [0x7f4cd5b4cf9f] -> /usr/lib64/dovecot/libdovecot.so.0(+0xb9515) [0x7f4cd5b4e515] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f4cd5b4d332] -> /usr/lib64/dovecot/lib20_fts_plugin.so(+0x96b4) [0x7f4cd50b86b4] -> /usr/lib64/dovecot/lib20_fts_plugin.so(fts_backend_update_deinit+0x45) [0x7f4cd50b872b] -> /usr/lib64/dovecot/lib20_fts_plugin.so(+0x142ed) [0x7f4cd50c32ed] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_sync_index+0x98e) [0x7f4cd5e4eed7] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x5f209) [0x7f4cd5e51209] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x5f497) [0x7f4cd5e51497] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_storage_sync_init+0xb2) [0x7f4cd5e517de] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x6d) [0x7f4cd5e2cc41] -> dovecot/imap(imap_sync_init+0xc7) [0x42e408] -> dovecot/imap() [0x42f96b] -> dovecot/imap() [0x42febc] -> dovecot/imap(cmd_sync_delayed+0x34) [0x42fef2] -> dovecot/imap(client_handle_input+0x138) [0x41e9d1] -> dovecot/imap(client_input+0xf5) [0x41eb02] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0xcd) [0x7f4cd5b6b054] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x209) [0x7f4cd5b6d5c1] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x24) [0x7f4cd5b6b1fd] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0xaf) [0x7f4cd5b6b149] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x2e) [0x7f4cd5aca603] -> dovecot/imap(main+0x300) [0x431169] -> /lib64/libc.so.6(__libc_start_main+0xf0) [0x7f4cd571c710] -> dovecot/imap(_start+0x29) [0x40c7b9] Sep 17 01:11:31 thunderstorm.reub.net dovecot: imap(reuben): Fatal: master: service(imap): child 1740 killed with signal 6 (core dumped) thunderstorm reuben # file core core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from 'dovecot/imap postlogin', real uid: 0, effective uid: 0, real gid: 0, effective gid: 0, execfn: '/usr/libexec/dovecot/imap', platform: 'x86_64' thunderstorm reuben # gdb /usr/libexec/dovecot/imap core GNU gdb (Gentoo 7.11.1 vanilla) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.

Hello, I'm using dovecot lmtp with Postfix. I'm enabling SMTPUTF8 (EAI), but when Postfix (v 3.1.2) tries to deliver the message to dovecot-lmtp it receive this error: status=bounced (SMTPUTF8 is required, but was not offered by host dlvmx.espsrv.net[private/dovecot-lmtp] I'm not sure if Dovecot lda and lmpt support EAI and how can I enable it. I've just found and old thread: http://www.dovecot.org/list/dovecot/2013-January/087756.html Thanks for your help. -- Igor Colombi

pop3 deleted count
by Dave 16 Sep '16

16 Sep '16

On pop3 logout, we're seeing log lines where the deleted count is blank (using default pop3_logout_format), so "del=%d/%m" is displaying in the logs as: "del=/1186" for example. In src/pop3/pop3-client.c:552: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : 0; Shouldn't this be: tab[4].value = client->delete_success ? dec2str(client->deleted_count) : "0"; (very minor bug) -- Dave

Hello Timo, from the maintainer of the OpenCSW package I got the below answer. As the newly build package yields another different commit hash (which I cannot find on GitHub too), I would ask, if you are sure that the commit hash-output in 'doveconf -n' is generated correctly?

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

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.

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

Sure, I understand this, but it's handy in lots of cases where you need to loading from an alternate location. Not everyone has access to resource to recompile. > 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). 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).

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
