Cached message size smaller than expected

Hi Since i upgraded to Dovecot 2.2.15 i start experiencing "Cached message size smaller than expected" errors that render a whole imap folder unusable as dovecot panics. I used Timo Sirainen maildir-size-fix.pl v1.1 script to try to fix the sizes but it does not seem to work trying to access the maildir produces this log in dovecot: Jan 07 19:34:13 imap(forumed(a)forumed.biz): Error: read(zlib(/var/spool/exim/mail/forumed.biz/forumed/.Sent/cur/1386527120.M104960P2012.mail,S=7725131:2,S)) failed: Cached message size smaller than expected (7725131 < 7729083, box=Sent, UID=2734) Jan 07 19:34:13 imap(forumed(a)forumed.biz): Error: Maildir filename has wrong S value, renamed the file from /var/spool/exim/mail/forumed.biz/forumed/.Sent/cur/1386527120.M104960P2012.mail,S=7725131:2,S to /var/spool/exim/mail/forumed.biz/forumed/.Sent/cur/1386527120.M104960P2012.mail,S=7729084:2,S Jan 07 19:34:13 imap(forumed(a)forumed.biz): Error: Corrupted index cache file /var/spool/exim/mail/forumed.biz/forumed/.Sent/dovecot.index.cache: Broken physical size for mail UID 2734 Jan 07 19:34:13 imap(forumed(a)forumed.biz): Panic: file istream.c: line 167 (i_stream_read): assertion failed: (old_size <= _stream->pos - _stream->skip) Jan 07 19:34:13 imap(forumed(a)forumed.biz): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x75e1a) [0x7feb14469e1a] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x75e96) [0x7feb14469e96] -> /usr/local/lib/dovecot/libdovecot.so.0(i_error+0) [0x7feb1441b2bf] -> /usr/local/lib/dovecot/libdovecot.so.0(i_stream_read+0x214) [0x7feb144731f4] -> /usr/local/lib/dovecot/libdovecot.so.0(i_stream_read_data+0x52) [0x7feb144733b2] -> /usr/local/lib/dovecot/libdovecot.so.0(message_get_body_size+0xa9) [0x7feb1445da89] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(index_mail_init_stream+0x16f) [0x7feb1473795f] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0x2dacc) [0x7feb14701acc] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mail_get_stream+0x4d) [0x7feb1470f3ed] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0x2e3e8) [0x7feb147023e8] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mail_get_virtual_size+0x2b) [0x7feb1470f07b] -> dovecot/imap() [0x41b2f5] -> dovecot/imap() [0x419d6c] -> dovecot/imap(imap_fetch_more+0x31) [0x419fa1] -> dovecot/imap() [0x40ebb0] -> dovecot/imap(command_exec+0x3d) [0x4183ad] -> dovecot/imap() [0x416a7e] -> dovecot/imap(client_output+0x10b) [0x417adb] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x931d9) [0x7feb144871d9] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x5b) [0x7feb1447b0db] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xaf) [0x7feb1447c27f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7feb1447b169] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7feb1447b1f8] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7feb14420193] -> dovecot/imap(main+0x2b0) [0x4210d0] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7feb140b1c4d] -> dovecot/imap() [0x40bea9] Jan 07 19:34:13 imap(forumed(a)forumed.biz): Fatal: master: service(imap): child 9337 killed with signal 6 (core not dumped) 1386527120.M104960P2012.mail,S=7725131:2,S is actually a gzip compressed mail, it's compressed size (file system size) is 7725131 bytes after dovecot panic it's automatically renamed to 1386527120.M104960P2012.mail,S=7739837:2,S by dovecot dovecot -n # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.3 auth_cache_size = 10 M auth_cache_ttl = 1 days auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyz01234567890.-_@ disable_plaintext_auth = no hostname = pop.olsns.net log_path = /usr/local/log/dovecot.log mail_fsync = never mail_gid = mail mail_plugins = " zlib" mail_uid = exim mailbox_list_index = yes maildir_very_dirty_syncs = yes namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } plugin { zlib_save = gz zlib_save_level = 6 } pop3_fast_size_lookups = yes protocols = imap pop3 service auth { user = root } service imap-login { executable = /usr/local/libexec/dovecot/imap-login inet_listener imap { address = 82.98.162.142 127.0.0.1 } service_count = 100 user = dovecot } service imap { service_count = 100 } service pop3-login { executable = /usr/local/libexec/dovecot/pop3-login inet_listener pop3 { address = 82.98.162.142 } service_count = 100 user = dovecot } service pop3 { executable = /usr/local/libexec/dovecot/pop3 service_count = 100 } ssl_cert = </usr/local/etc/dovecot/dovecot.pem ssl_key = </usr/local/etc/dovecot/dovecot.key userdb { driver = prefetch } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol imap { mail_plugins = " zlib imap_zlib" }

Kerberos problems with /dev/null as dovecot home
by Roland Hopferwieser 07 Jan '15

07 Jan '15

Hi, this is for documentation if someone else has the same problem. After migration from Dovecot 1 to 2.2. it was no longer able use Kerberos (Heimdal). I found out that dovecot tries to read ~/.krb5/config in the home of the dovecot user. This file doesn't need to exist, but if the home is set to /dev/null, it will not work. Maybe it would be nice to have an error message for this case. Regards, Roland

'ssl_cipher_list' setting
by Yoshito Takeuchi 06 Jan '15

06 Jan '15

Hi, I am Yoshi, Japanese. I used FreeBSD 10.1 Dovecot 2.2.15 I want pop3s, so I made /usr/local/etc/dovecot/local.conf ssl = yes ssl_cert = </usr/local/etc/dovecot/server.pem ssl_key = </usr/local/etc/dovecot/server.key ssl_ca = </usr/local/etc/dovecot/ca.pem ssl_protocols = !SSLv2 !SSLv3 ssl_cipher_list = ALL:!LOW:!SSLv2:!SSLV3:!EXP:!aNULL:!RC4 It's work fine. But, change ssl_cipher_list = ALL:!LOW:!SSLv2:!SSLv3:!EXP:!aNULL:!RC4 ( SSLV3 -> SSLv3 ) I did trouble. /var/log/maillog Jan 6 05:41:53 example dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, TLS handshaking, session=<5e9 zuO0LVwB+PO8D> Is this bug ? or I did miss setting ? Thank you for reading. Yoshi

Crashes with tracebacks
by Timothe Litt 05 Jan '15

05 Jan '15

Crashes, redux. I hope I have provided all the information required for a solution. Many thanks in advance for having a look. I have 71 core files for a user, that all happened in the space of about 6 hours. It appears that mail delivered to 'Junk E-mail' is being accessed. I suspect they're all the same issue. I saw the same syslog entry a while back; did a resync & enabled process dumps. Naturally, it went away -- until this cluster of crashes. File system is ext3. It is NFS mounted by other machines, but only the local machine should be touching the mail directories. The user does not have an interactive login - it's an e-mail only account. This user's IMAP client is AppleMail. The delivery agent is procmail; Junk is detected by spamassassin; clamav is also present. pop3 is configured, but I don't think anyone uses it.

mdbox GUID
by Nagy, Attila 04 Jan '15

04 Jan '15

Hi, The dbox page says: "Each message has a 128 bit globally unique identifier (GUID)" I guess this is what guid_128_generate() generates. Is this believed to be really globally unique? As far as I can tell, in the current architecture they are -given there are enough time precision-, because all dovecot daemons are single threaded, so they have concurrency but doesn't have parallelism (they are not multi threaded). I would like to list all of the messages, with this GUID as the unique identifier, so a collision would be fatal here...

ntlm_auth random failures with dovecot
by Jason Gunthorpe 04 Jan '15

04 Jan '15

I'm still a bit fuzzy on exactly what has blown up here since my 1.2 install (or maybe it was broken then and I never noticed), but it looks like the way dovecot is calling out to ntlm_auth is violating the --helper-protocol=squid-2.5-ntlmssp scheme. The issue is how it handles simultaneous clients connecting - for instance launching thunderbird with NTLM auth creates multiple imapds that all have to be auth'd. Since dovecot doesn't (and apparrently didn't in 1.2?) serialize this it ends up sending a jumble to ntlm_auth. Strace sayth, as example: read(0, "YR xxxxxxx=\n", 4096) = 48 read(0, "YR xxxxxxx=\n", 4096) = 48 read(0, "KK xxxxxxx=\n",4096) = 176 read(0, "KK xxxxxxx=\n",4096) = 176 That is two clients connecting at once, and the sequence has become jumbled. Fiddling around with ntlm_auth manually I can get it to give me this: YR xxx # 1 TT xxx # 1 YR xxx # 2 TT xxx # 2 KK xxx # 2 AF jgg # 2 KK xxx # 1 Called NTLMSSP after state machine was 'done' GENSEC login failed: NT_STATUS_INVALID_PARAMETER NA NT_STATUS_INVALID_PARAMETER Ie, reordering the sequence (# 1 and # 2) causes it to tell you that, no, the sequence cannot be reordered. To me this says the samba folks expect that the YY/TT/KK/AF sequence is *NOT* reordered. The implication is that the mech-winbind in dovecot must seralize everything, and it doesn't! So, this is fairly broken, I can hit these failure causes with a high probability when using thunderbird. Any thoughts on how to repair this? The simplest answer would be to pool and assign a ntlm_auth process to each incoming auth context, or to actually serialize auth. But it can't treat ntlm_auth as a stateless helper. Jason

[PATCH] LAYOUT=imapdir is broken in v2.2
by Jason Gunthorpe 04 Jan '15

04 Jan '15

The next thing I noticed in my v1.2 -> 2.2 upgrade is that mail_location = maildir:[..]:LAYOUT=imapdir is broken, the symptom is dovecot returning this to the client when requesting any mailbox beyond INBOX: Character not allowed in mailbox name: ' Which is actually trying to say "Character not allowed in mailbox name: '\0'", but since the %c is not escaped it ends up with the truncated string. This patch fixes it: diff --git a/src/lib-storage/list/mailbox-list-maildir.c b/src/lib-storage/list/mailbox-list-maildir.c index c99a2900a6d6..ae5f35d955ac 100644 --- a/src/lib-storage/list/mailbox-list-maildir.c +++ b/src/lib-storage/list/mailbox-list-maildir.c @@ -46,6 +46,7 @@ static struct mailbox_list *imapdir_list_alloc(void) list = p_new(pool, struct maildir_mailbox_list, 1); list->list = imapdir_mailbox_list; list->list.pool = pool; + list->sep = '.'; list->global_temp_prefix = IMAPDIR_GLOBAL_TEMP_PREFIX; list->temp_prefix = p_strconcat(pool, list->global_temp_prefix, Analysis: I noticed this while upgrading a dovecot install from 1.2.15 (squeeze) to 2.2.13 (jessie).

dovecot and ntlm_auth through winbind
by Jason Gunthorpe 04 Jan '15

04 Jan '15

Hi all, I am upgrading a dovecot 1.2 installation to a 2.2 installation and have found and fixed a number of problems.. I've seen several postings in the archive about ntlm_auth not working, and it is true, there are several regressions in dovecot here. The first and simplest is that the enablement instructions in the wikki are wrong. ntlm_auth must be called as root, which is what 1.2 did. 2.2 defaults to calling it as the auth user which subtly doesn't work: Dec 30 20:30:21 quartz dovecot[8439]: auth: Error: Login for user []\[jgg]@[wakko] failed due to [Reading winbind reply failed!] Dec 30 20:30:21 quartz dovecot[8439]: auth: Error: ../auth/ntlmssp/ntlmssp_server.c:454: Checking NTLMSSP password for \jgg failed: NT_STATUS_UNSUCCESSFUL Dec 30 20:30:21 quartz dovecot[8439]: auth: Error: GENSEC login failed: NT_STATUS_UNSUCCESSFUL Dec 30 20:30:21 quartz dovecot[8439]: auth: Error: winbind: ntlm_auth exited with exit code 0 The fix is simple, run auth as root: service auth { user = root } This ended up as debian bug #774263 which has a few more details.

Help with installing Apache Solr with Dovecot 2.2
by Kev Lau 03 Jan '15

03 Jan '15

Hi, I am relatively new to Apache Solr and I am trying to get it to integrate with Dovecot 2.2 running on Ubuntu 14.04 and needed a little help with configuration. The following steps I have already configured. Appreciate if someone could help, so please help me! 1. Apache Solr installed, up and running 6406 [main] INFO org.eclipse.jetty.server.AbstractConnector ? Started SocketConnector@0.0.0.0:8983 I can then ssh into it and see the running solr admin. ssh -t -L 8983:localhost:8983 user(a)mydomain.com 2. Schema file added startTime: 3 minutes ago instanceDir: /opt/solr/solr/collection1/ dataDir: /opt/solr/solr/collection1/data/ In my collection1 core selector I have the following files:- 1.solrconfig.xml 2.schema.xml The output of schema.xml is shown below:- <?xml version="1.0" encoding="UTF-8" ?>  <schema name="dovecot" version="1.5"> <field name="_version_" type="long" indexed="true" stored="true"/> <field name="_root_" type="string" indexed="true" stored="false"/> <types>  <fieldType name="string" class="solr.StrField" omitNorms="true"/> <fieldType name="long" class="solr.LongField" omitNorms="true"/> <fieldType name="slong" class="solr.SortableLongField" omitNorms="true"/> <fieldType name="float" class="solr.FloatField" omitNorms="true"/> <fieldType name="boolean" class="solr.BoolField" omitNorms="true"/> <fieldType name="text" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/>  <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="15"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0"/> <filter class="solr.LowerCaseFilterFactory"/>  <filter class="solr.SnowballPorterFilterFactory" protected="protwords.txt"/> <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> </analyzer> </fieldType> </types> <fields> <field name="id" type="string" indexed="true" stored="true" required="true" /> <field name="uid" type="slong" indexed="true" stored="true" required="true" /> <field name="box" type="string" indexed="true" stored="true" required="true" /> <field name="user" type="string" indexed="true" stored="true" required="true" /> <field name="hdr" type="text" indexed="true" stored="false" /> <field name="body" type="text" indexed="true" stored="false" /> <field name="from" type="text" indexed="true" stored="false" /> <field name="to" type="text" indexed="true" stored="false" /> <field name="cc" type="text" indexed="true" stored="false" /> <field name="bcc" type="text" indexed="true" stored="false" /> <field name="subject" type="text" indexed="true" stored="false" /> </fields> <uniqueKey>id</uniqueKey> <defaultSearchField>body</defaultSearchField> <solrQueryParser defaultOperator="AND" /> </schema> 3.

Disabling compressed storage for one public namespace - is it possible?
by Marc Stürmer 02 Jan '15

02 Jan '15

Greetings, I've got Dovecot 2.2.X running with gzip compressed storage enabled by default. My question though is: is it possible to disable this compressed storage for one specific, public namespace only? I haven't found quite much information about it on the wiki. Thanks in advance.

dovecot 2 low TCP speed (fetching big mail)
by Wojciech Puchar 01 Jan '15

01 Jan '15

i use dovecot 2 under FreeBSD (dovecot2-2.2.15 compiled from ports). tried both with kqueue enabled or not. everything works very fast, EXCEPT fetching big mail. tried multiple clients (thunderbird on windows, alpine on the same server, alpine on other unix server connected by 1Gb/s LAN) and fetching peaks at 1MB/s. NO SSL! could you please point me where to search for a problem. hints: writing over IMAP (eg. writing to Sent folder) works at full speed. Doesn't seem like a problem with unix server, every other service goes at speed 70-100MB/s both directions (like samba, ftp). tried to turn off "kqueue" compile time option, no difference. Please give me a hint at least what to check. Does dovecot use other way to sent data over TCP socket than other programs? thank you.

Postfix and Dovecot SASL - wiki update
by Dan Langille 01 Jan '15

01 Jan '15

I wanted to mention I updated the Postfix and Dovecot SASL wiki entry yesterday. http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL The entry: submission inet n - - - - smtpd was incorrect. It should be: submission inet n - n - - smtpd By specifying n for chroot, it ensures that DNS lookups can occur. Otherwise, if you are using reject_unknown_recipient_domain the following error will occur: Recipient address rejected: Domain not found Hope that helps. — Dan Langille http://langille.org/

Authenticating Virtual Users without domain
by Leon Kyneur 31 Dec '14

31 Dec '14

Hi, I'm trying to migrate a large number of users to a new Dovecot cluster. The existing mail system allows a user to authenticate with a bare username if they have connected to the correct local IP on the server. e.g. imap.somedomain.com = 1.1.1.1 imap.anotheromain.com = 2.2.2.2 charlie@somedomain can authnenticate as 'charlie' or 'charlie(a)somedomain.com' as long as he is connected to imap.somedomain.com (1.1.1.1) likewise for bare usernames if they connect to imap.anotherdomain.com. A previous colleague actually achieved this by hacking with the Dovecot source code and writing in a lookup table feature. The code is very old and won't patch cleanly to the latest 2.2.15 source. Another platform we are using (commercial product) also has this feature but we also need to migrate these users to Dovecot. I already have a Dovecot proxy layer for mailbox lookup - so ideally I would like to do this on my Dovecot proxies. I know I can also do this kind of thing if I swapped my dovecot proxy for Perdition, however I don't really want to do that. I've looked into checkpassword scripts and could possibly make something work (albeit ugly) - is this the right direction to take here? Thanks, Leon

Segmentation fault in pigeonhole lib-sieve
by Orion Poplawski 30 Dec '14

30 Dec '14

The sieve plugin for Thundirbird likes to rapidly compile work in progress sieve scripts to continually give feedback on any errors in the script. This can trigger segmentation faults in lib-sieve with certain pathologically incomplete sieve scripts. One example: #0 tag_comparator_validate (valdtr=0x7f291aa713a0, arg=0x7fff5c3cfa58, cmd=0x7f291aa69360) at sieve-comparators.c:143 143 if ( (*arg)->type != SAAT_STRING ) { Missing separate debuginfos, use: debuginfo-install bzip2-libs-1.0.6-12.el7.x86_64 glibc-2.17-55.el7_0.3.x86_64 sssd-client-1.11.2-68.el7_0.6.x86_64 zlib-1.2.7-13.el7.x86_64 (gdb) list 138 *arg = sieve_ast_argument_next(*arg); 139 140 /* Check syntax: 141 * ":comparator" <comparator-name: string> 142 */ 143 if ( (*arg)->type != SAAT_STRING ) { 144 sieve_argument_validate_error(valdtr, *arg, 145 ":comparator tag requires one string argument, but %s was found", 146 sieve_ast_argument_name(*arg) ); 147 return FALSE; (gdb) print arg $1 = (struct sieve_ast_argument **) 0x7fff5c3cfa58 (gdb) print *arg $2 = (struct sieve_ast_argument *) 0x0 So sieve_ast_argument_next() is returning NULL and we're trying to dereference it without checking.

PAM issues on OS X Yosemite
by Markus Mayer 30 Dec '14

30 Dec '14

Hi, I have been running dovecot successfully on OS X Mavericks for several months. After upgrading to Yosemite, however, PAM authentication for dovecot is failing. Or rather, creating the PAM session is failing. Either way, I can't get to my e-mail. $ /usr/pkg/sbin/dovecot --version 2.2.15 $ /usr/pkg/sbin/dovecot -n # 2.2.15: /usr/pkg/etc/dovecot/dovecot.conf # OS: Darwin 14.0.0 x86_64 hfs auth_debug = yes auth_verbose = yes mail_location = maildir:/Volumes/Secure/%u/Maildir 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 { args = session=yes dovecot driver = pam } ssl_cert = </usr/pkg/etc/openssl/certs/dovecot.pem ssl_key = </usr/pkg/etc/openssl/private/dovecot.pem userdb { driver = passwd } $ defaults read "/System/Library/CoreServices/SystemVersion" ProductVersion 10.10.1 Dec 30 13:21:47 my.host.name dovecot[49247]: auth: Debug: auth client connected (pid=49289) Dec 30 13:21:51 my.host.name dovecot[49247]: auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=3bBdlHULNgAAAAAAAAAAAAAAAAAAAAAB lip=::1 rip=::1 lport=143 rport=52278 resp=<hidden> Dec 30 13:21:51 my.host.name dovecot[49247]: auth-worker(49286): Debug: pam(markus,::1): lookup service=dovecot Dec 30 13:21:51 my.host.name dovecot[49247]: auth-worker(49286): Debug: pam(markus,::1): #1/1 style=1 msg=Password: Dec 30 13:21:51 my.host.name dovecot[49247]: auth-worker(49286): Error: pam(markus,::1): pam_open_session() failed: session failure Dec 30 13:21:53 my.host.name dovecot[49247]: auth: Debug: client passdb out: FAIL 1 user=markus It does successfully verify my password. If I purposefully enter a wrong password the error becomes "pam_authenticate() failed: authentication error (password mismatch?)". So that portion is okay. Do you have any suggestions how I might find out why pam_open_session() is failing? The auth process *is* running as root. I have tried these two PAM configurations. The first one based on Maverick's /etc/pam.d/login and used to work fine on Mavericks. # dovecot: auth account password session auth optional pam_krb5.so use_kcminit auth optional pam_ntlm.so try_first_pass auth optional pam_mount.so try_first_pass auth required pam_opendirectory.so try_first_pass account required pam_nologin.so account required pam_opendirectory.so password required pam_opendirectory.so session required pam_launchd.so session required pam_uwtmp.so session optional pam_mount.so I tried to simplify it by using the one suggested on dovecot's PAM wiki. # dovecot: auth account password session auth required pam_opendirectory.so try_first_pass account required pam_nologin.so account required pam_opendirectory.so password required pam_opendirectory.so On Yosemite, neither works. Or, quite possibly, both configurations are fine and the problem lies elsewhere. Any pointers would be greatly appreciated. In the mean time I'll be using auth-passwdfile, since that works. Thanks, -Markus

Hi, Great to see Thunderbird support SPECIAL-USE now. I would like to hear the list about the intended use of SPECIAL-USE. I get the impression from several earlier mails here that the intention is for the server to globally decide what the folder-name of a specific SPECIAL-USE folder is for all users. That's the way the documentation exemplifies it and what I get from posts like this: http://www.dovecot.org/list/dovecot/2013-February/088129.html I get the point that if *all* clients ignored the real folder-name and only obeyed SPECIAL-USE, the clients could locally in the GUI decide language and name of the \Sent, \Drafts, \Trash folders. And the real folder name would become just an opaque identifier. However that's not how the world is like. There are plenty of clients ignoring SPECIAL-USE and placing meaning in the actual folder name in a language of their own choice. It seems natural for me to let the user configure their own individual SPECIAL-USE tagging according to their language and/or mix of IMAP clients. - either by setting IMAP METADATA (RFC5464) or by having the userdb return entries like: "namespace/inbox/Papperskorg/specialuse=\Trash" (for a swede) /Peter PS: Also... Isn't there a need for a Sieve extension to allow "fileinto" to target a folder based on special-use ?

What on earth is going on here? There must be something > fundamental that I am missing. "doveadm pw" is working correctly. CRAM-MD5 and SSHA use hashing in 2 different ways to authenticate a user. CRAM-MD5 is a challenge-response system where the server sends the client a random string each and every session. The client hashes the password and the random string and sends it to the server as proof of authenticity. The server performs the same calculation to verify. However, the server needs to know the password (or password equivalent) in order to duplicate the hash calculation. SSHA precomputes the random strings (salt) and hashes the password with it, and stores both salt and hash in the password database. During authentication, the password is (or ought to be) transmitted plain within a SSL connection from the client to the server, then the server hashes the password with the stored salt and compares with the hash in the database. Every time you run "doveadm pw -s sha" a new random salt is generated, hence a new hash is produced even though you use the same password. You would use challenge-response in situations where the communication channel is insecure (i.e. non-SSL). However, the drawback is the password database contains enough information for someone to authenticate if it should fall into the wrong hands. Joseph Tam <jtam.home(a)gmail.com>

The problem with "slowness" is that it can result from just about anything. I've seen reports of slowness caused by LDAP handups, filesystem and I/O polling, client issues, network issues, firewall issues, anti-virus stuff, resource starvation. That's just the stuff I remember. You'll need to dig further to reduce the scope of where it can be going wrong. I would suggest getting hints from - process tracing - network snooping - logs Test if it's a mail client issue by sampling more than one mail client (or better yet, talk IMAP directly to the server via telnet or netcat and download a large piece of Email). If that provokes a problem, work your way back to the server and do the same thing on the server itself (bypassing the network stack) and see if the problem still persists. Depending on what you find out, at least you'll know which side of the fence you should be looking at. (Also, asks yourself the obvious question: did you change anything before dovecot performance went down the tubes? New hardware? Patches?) Joseph Tam <jtam.home(a)gmail.com>

Deleting files in sdbox
by Jeff Mitchell 28 Dec '14

28 Dec '14

Hello, I'm curious as to what happens if I were to manually delete files in an sdbox on the server. A long time ago -- I'm not sure how, as it was several years ago -- something happened and a number of users got a large number of mail messages duplicated. Literally duplicated -- all headers, all body content. I have a script that can find these duplicated messages (by ignoring the first few and last few lines of each message, and using SHAs to compare and find the duplicates). However, I don't see a doveadm style command to manually delete messages, except for doveadm-expunge. In the past I've used that with search queries but my experience is that trying to do many individual operations on individual files with doveadm-expunge can be quite slow. So, if Dovecot is going to just say "huh, my indexes/metadata are wrong, lemme rebuild them", I'd rather just rm the messages and let Dovecot do its thing. Again, this is with sdbox storage. Dovecot version is 2.2.9. Thanks! --Jeff

Thunderbird supports SPECIAL-USE (Merry x-mas!)
by Patrick Ben Koetter 27 Dec '14

27 Dec '14

I've waited about two years to write this mail... :) As of Dezember, 24th Mozilla Thunderbird can handle SPECIAL-USE. The patch, which adds the required functionality, has passed review and TBs nightly build was successful. The next official Thunderbird release (version 38, release date 2015-05-19) will very likely ship SPECIAL-USE included. \o/ SPECIAL USE is an IMAP extension. It means less mailbox chaos for admins. But more than that it means less configuration work and easier orientation for end users. If IMAP server and client are capable of SPECIAL-USE [1] the server may tell the client some of the folders (Inbox, Drafts, Sent, Trash etc.) are reserved for SPECIAL-USE. Any client, capable of SPECIAL-USE, may adapts its local folders to the servers view. It may map e.g. "Sent Items" to "Sent", "Deleted Items" to "Trassh" etc. pp. All this takes place automatically. No more user interaction. No more locale problems. When all components - server, desktop-, webmail-, and mobile client - can handle SPECIAL-USE live becomes easier. Clients don't create their own 'special folders'. They understand special folders already exist and adapt. No more superfluous ambiguous folders. Users will know where their messages have been stored. Note: Combined with automx [2] users will only have to enter their realname, mail address and (optional) password and their client will setup all the rest automatically. SPECIAL-USE started as a suggestion to friends at IETF. We sponsored its implementation in Dovecot [3], when it had become a RFC standard. Then we took out to bring it to Thunderbird. This took use longer than expected. The moment we had begun to work on it, Mozilla withdrew most people from the Thunderbird team and reassigned them to Firefox OS. Things slowed down significantly and Microsoft Outlook became the first mail client to adopt SPECIAL-USE. Two years later - together with Ben Bucksch (Thunderbird developer) - we finally succeeded and it is about time to close the RFE [4]. Nobody should have to spend more time than required to configure their client. Everyone should be able to focus on their primary goal - communication via mail. We - sys4 and our business partner Becon - sponsored SPECIAL-USE. I hope SPECIAL-USE will make your and your customers life easier. The patch just became ready for x-mas. :) p@rick P.S.

Awfully slow dovecot

Hi, We’re using dovecot 1.0.7, which seems to be the latest version available on CentOS 5. Downloading emails are dead slow.

Curious dovecot behavior with service_count = 0

Hello, I'm not experiencing this problem at all with service_count = 1 With service_count = 0, this is what I got randomly in my logs: TLS: SSL_read() syscall failed: Connection reset by peer To be successfully logged, the user have to initiate a new connection. I primary thought about vsz_limit but I've put this value to 10GB (yes this is very overkill, that was just for the test) and that don't change anything. I use the lastest version of dovecot. Any ideas ? Thanks.

Re: Maildir permissions on creation?

doveadm pw generates different hash each time it is invoked !?
by reik red 26 Dec '14

26 Dec '14

I am absolutely dumbfounded by "doveadm pw". My understanding is that the command should be used to create a hashed password that should in turn be placed into /etc/dovecot/passwd Here comes the "dumbfounded" part. I was creating a new virtual user, running doveadm pw to generate the hashed password. But when I tried to login via imap, the password was rejected. So I started checking that I had populated /etc/dovecot/passwd with the correct values, and in the process I ran "doveadm pw" again to make certain I had not accidentally pasted the wrong value along with a username. (I'm re-submittting after setting up a subscription, so I don't have to wait for the moderator) , What happened next surprised me greatly: if I specify "-s ssha", the resulting hashed password changes each time I invoke "doveadm pw", but if I do not specify the hashing method, I get the same password each time (as I expect). What on earth is going on here? There must be something fundamental that I am missing. ============================================== Illustrative example: machine(user) 6136 > doveadm pw -u joebob Enter new password: Retype new password: {CRAM-MD5}00747cf2ffaf11c5ea4a64979c3901fc1d20dee13f480bb598f7d8575b23e61b machine(user) 6137 > doveadm pw -u joebob Enter new password: Retype new password: {CRAM-MD5}00747cf2ffaf11c5ea4a64979c3901fc1d20dee13f480bb598f7d8575b23e61b #SAME, as expected machine(user) > doveadm pw -u glorg Enter new password: Retype new password: {CRAM-MD5}00747cf2ffaf11c5ea4a64979c3901fc1d20dee13f480bb598f7d8575b23e61b #another surprising behavior: The (virtual) username specified does not affect the hash!!! machine(user) 6138 > doveadm pw -u joebob -s ssha Enter new password: Retype new password: {SSHA}AtjINkQra967qIhU6khRED4U1x3aKwDi machine(user) 6139 > doveadm pw -u joebob -s ssha Enter new password: Retype new password: {SSHA}fZiFlHPKDn6ESM/gnUIcjJ14hRlH10DV # DIFFERENT, very unexpected ============================================== I'm on fedora 19, using dovecot.x86_64 version 1:2.2.15-1.fc19 per yum.

director + lmtp + ldap user
by Lazy 25 Dec '14

25 Dec '14

Hi, recently I have migrated our prevoius dovecot-lda to 2.2 with director + lmtp. And we are having some issues. When lmtp delivers to ldap uid names everything works except sieve vacation (login is not found in headers so reply is not sent). When using full email addresses in rcpt to vacation works but usernames are inconsistent (one user can login using his email address, or aliases, or uid). To fix that in ldap settings a have added uid=user which should be setting the username to approperate values. Most of the times it works but some deliveries are using email addresses not ldap uid's which seems to break dict quota's. It's must be related to auth cache (flushing the cache fixes the issue temporarly for given account). I think that the cache can be "polluted" by some other dovecot service. Does anyone have an idea where this can be comming from ? doveadm auth lookup -f user mon(a)test.com returns expected ldap uid no email address Thanks in advance for any help.

Maildir permissions on creation?
by Von Random 24 Dec '14

24 Dec '14

Hello. In my configuration dovecot reads home from mysql and uses no variables within it. It uses Maildir++ storage with virtual users. I also happen to use LMTP. I want to use a backup solution that does not involve running itself as root. Neither do I want to run it as dovecot's mail user. And there lies the problem: dovecot creates maildirs with 0700 and files within them inherit that set of permissions. And there seems to be no sane way to control it. I think I've figured out what to patch in order to change that default, but if possible, I'd like to avoid doing that. tl;dr: is it possible to change the default set of permissions for new maildirs created by dovecot?

Configuring LMTP/IMAP proxy
by Le Moing, Guenhaël 23 Dec '14

23 Dec '14

Hi, First, my version: [root@centos1 conf.d]# dovecot --version 2.2.15 [root@centos1 conf.d]# I have already configured dovecot that way (on one single VM, so everythinh is stored on the same machine) - A post fix server sending out to LMTP - LMTP is the dovecot LMTP server, configured with "lmtp-proxy= no", - LMTP checks the users receiving messages by using Linux passwd file "userdb" section in auth-passwdfile.conf.ext, - IMAP LOGINS are authenticated using DIGEST-MD5 also configured in auth-passwdfile.conf.ext : - # Authentication for passwd-file users. Included from 10-auth.conf. # # passwd-like file with specified location. # <doc/wiki/AuthDatabase.PasswdFile.txt> passdb { driver = passwd-file args = scheme=DIGEST-MD5 username_format=%n /etc/dovecot/users.DIGEST-MD5 #args = scheme=CRAM-MD5 username_format=%n /etc/dovecot/users.CRAM-MD5 } userdb { driver = passwd # Default fields that can be overridden by passwd-file #default_fields = quota_rule=*:storage=1G default_fields = uid=root gid=root home=/home/%n # Override fields from passwd-file #override_fields = home=/home/virtual/%u } This works fine, I can send messages through SMTP, and read them using IMAP access. But now, I woukd like to have amore structured architecture with : - A LMTP server configured as PROXY : has to identify the user, and proxy the request to the backen LMTP server (where its mailbox will stand) - On backend, I also have to start another LMTP serevr, but not configured in proxy mode of course, - Same for IMAP : IMAP proxy first checking LOGIN credentials, and then forwarding to IMAP server running on backend. As a first step, I would like to continue using my files to authenticate uses (so passwd file , and users.DIGEST-MD5), but final goal will be using a MySQL DB. So my main question are : 1) I just made a test and changed "lmtp_proxy" to "yes" in my 20_lmtp.cong file, but, strangely, this did not cah nge anything ! The LMTP process still receives mails and stores them on the local host , 2) Are there any documentation describing this process in details ? I only found some pieces on wiki pages, but not enough unfortunately ... 3) Are there some configuratiion files ready to use for my configuration. Thanks in advance. Cordialement. Guenhaël.

zlib, mdbox and spam filtering scripts
by Philon 22 Dec '14

22 Dec '14

Hi all, I am quite happily running a dovecot setup with maildirs. This was once running courier but since the migration I have never ever looked back. Now, with growing userbase I’m looking into using zlib compression and mdbox instead of maildir. This seems to go quite well using dsync on a testbed server. So let’s go production! Before final decision I came across this: - I’m using a spam learning address, where users forward their mails to train SpamAssassin. - there is a cron script on the server, mime-stripping the attachments and feeding them into SA - works quite well even for the still numerous POP users So well… compression ok, I could add a gunzip into the script and go from there. But mdbox seems only accessible via dovecot. I don’t think that accessing via IMAP makes sense for a local script. So I would block myself out when using mdbox. How are your spam/ham training routines? How do you feed SA? thank you! Philon

lmtp usernames with -
by Lazy 19 Dec '14

19 Dec '14

Hello I have a problem with lmtp delivery to usernames with '-' char. Everythong after - is ignored. when delivering to test-test2 the error message is. User doesn't exist: test I suspect this is a sideefect of auth_username_format = %Lu I have tried %Ln without success. Imap works without problems for those users. How can I disable this mapping for lmtp and use verbatim username for lookup. Thanks in advance for any answers.

LDAP: Connection appears to be hanging, reconnecting
by Matthias Egger 17 Dec '14

17 Dec '14

Hello List I have a strange problem here which i try to analyse, but i'm stuck. Maybe someone has a hint? What happened: A few weeks ago one of the LDAPS Servers which is not maintained by us has crashed. From that moment on, users could still login to check their emails, but they were not able to send any email through postfix (which uses smtpd_sasl_type = dovecot) What i do not understand, is why did dovecot not switch to the second configured LDAPS Server? It looks like it retried for ever to reconnect to the crashed LDAP Server. From the moment of the crash we see a lot of Errors like these in our logfiles: Nov 30 16:51:53 servername dovecot: [ID 583609 mail.error] auth: Error: ldap(userone,USERS_IP1,<WKiTeBUJQQBUSAnE>): Connection appears to be hanging, reconnecting AND Nov 30 16:51:59 servername dovecot: [ID 583609 mail.error] auth: Error: plain(usertwo,USERS_IP2,<QgJvcBUJqABTTWrJ>): Request 1982.83548 timed out after 151 secs, state=1 The used dovecot version is 2.2.13, runs on a solaris 10 system and the configuration for passdb and userdb are: passdb { args = /etc/dovecot-ldap.conf default_fields = deny = no driver = ldap master = no name = override_fields = pass = no result_failure = continue result_internalfail = continue result_success = return-ok skip = never } userdb { args = /etc/dovecot-ldap.conf default_fields = driver = ldap name = override_fields = result_failure = continue result_internalfail = continue result_success = return-ok skip = never } And the dovecot-ldap.conf contains (obfuscated): uris = ldaps://server2.tld ldaps://server1.tld ldaps://server4.tld ldaps://server3.tld dn = ... dnpass = ... ldap_version = 3 auth_bind = yes base = ... scope = onelevel user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = ... pass_attrs = uid=user pass_filter = ... The strange thing is, that with the very same binaries and configuration (okay, some minimal modifications have been made to bind to the correct interfaces...) a test on our testsystem works as it should. When we shutdown slapd, dovecot recognizes it an connects to the alternate LDAPS. When we shutdown slapd and start a netcat (just to let something listening without responding)... you guess it. Dovecot does recognize it and switches over to the alternate testsystem. So on our testsystem, everything worked as it should. But the productive system did not. And since the LDAPS are not maintained by us it is somewhat hard to try to reproduce something. At least i got the logfiles from server2.tld and server1.tld. But they only show what i still knew. Our server connected to server2.tld until the crash happened. But server1.tld never got any connection. Has someone an idea what i could try to find out why dovecot did not switch to server1.tld?

dsync summary?
by Randall Gellens 17 Dec '14

17 Dec '14

Is there a way for dsync to report a summary of what it did? For example, when finished, it could report how many messages in how many folders were added (or deleted for a two-way sync) or had flags modified, and if any messages/folders were skipped due to errors or whatever. This could provide a sanity check that a sync looks like it worked. -- Randall Gellens Opinions are personal; facts are suspect; I speak for myself only -------------- Randomly selected tag: --------------- Hippogriff: An animal (now extinct) which was half horse and half griffin. The griffin was itself a compound creature, half lion and half eagle. The hippogriff was actually, therefore, only one quarter eagle, which is two dollars and fifty cents in gold.

replication - more than 2 servers?
by Ron Cleven 17 Dec '14

17 Dec '14

We tested dovecot for a fair amount of time and decided finally to put it into production under CentOS 7 (we are running 2.2.10). I just joined the list, so I apologize for what is probably a question that has been answered many times, but I was wondering if there are any plans to implement replication among 3 or more servers (all "masters", as with 2)? As best as I can tell, replication seems to be limited to 2 servers, and it is not obvious to me even how more than 2 would be supported syntactically in the configs. That is, what might be an example of the "mail_replica" clauses if such a thing was supported?

Problem with TLS and Outlook 2010

Dovecot 2.0.9 So I am trying to get my Outlook 2010 client to use TLS with Dovecot. The Outlook error that I get is: Log onto incoming mail server (IMAP): A secure connection to the server cannot be established. I have set the port to 143,993,995 none of them work, and the security to TLS. I have all of the certificates in the full chain installed on my machine and when viewing them they all show This certificate is OK.

Today dovecot was unable to delibery, via LDA, email in the Maildir and in the log i found the following error. Login via POP or IMAP works fine but is impossibile to delivery new email (the INBOX have about 135000 emails). I have delete all files in Maildir except cur/ new/ tmp/ and rebuild the dovecot cache, but the error is the same. Could be a sieve problem? In the user's home there was a file called .dovecot.lda-dupes.lock What is wrong?

Failed installation on Ubuntu with Postfix/Dovecot/Squirrelmail
by ghalvors78＠hushmail.com 15 Dec '14

15 Dec '14

Hello all, I did an install following a HOWTO document that has a fair number of positive reviews, but something went wrong along the way: https://www.digitalocean.com/community/tutorials/how-to-configure-a-mail-se… I made a couple deviations. I opted to not use StartSSL keys, and decided to stay with the default keys. Also, I chose to use Squirrelmail, but not Spamassassin. I tried to ensure that there are no issues with the Postfix installation (Dr. Venama and the team were quite helpful). I also had two Postfix book at my side, but I have none for Dovecot. While my goal is to get my server running, I would like to gain an understanding of Dovecot along the way, because sooner or later, it will break and I'll need to revisit the installation. First hint of a problem was that Squirrelmail would say the IMAP server dropped the connection on a successful login. So I went to a command line and used 'mail' to compose a test message from my laptop and see how the machine at Digital Ocean handled it. It didn't go over so well, in fact, it's generating errors as I'm writing this (every 5 minutes). For privacy, I swapped my domain name, for the generic example.com. Dec 14 20:24:18 example postfix/qmgr[13624]: EF3C0C0A17: from=<gary(a)Garys-MacBook-Pro.local>, size=597, nrcpt=1 (queue active) Dec 14 20:24:18 example dovecot: lmtp(21652): Connect from local Dec 14 20:24:18 example dovecot: lmtp(21652, bob(a)example.com) Error: user bob(a)example.com: Initialization failed: namespace configuration error: inbox=yes namespace missing Dec 14 20:24:18 example dovecot: lmtp(21652): Disconnect from local: Successful quit Dec 14 20:24:18 example postfix/lmtp[21651]: EF3C0C0A17: to=<bob(a)example.com>, relay=mail.example.com[private/dovecot-lmtp], delay=168169, delays=168169/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host mail.example.com[private/dovecot-lmtp] said: 451 4.3.0 <bob(a)example.com> Temporary internal error (in reply to end of DATA command)) Now when I was checking that Postfix wasn't the likely problem, one of them mentioned: http://archives.neohapsis.com/archives/postfix/2014-12/0189.html (Postfix-users archive) that I needed: namespace inbox { inbox = yes } But I'm curious why that I'm the only one that seems to have been nailed by this omission. A keyword search on 'namespace' only brought up a single comment. What are your thoughts? Below, I appended the configuration files that I modified. I tried to compress them to a minimum space for the list by omitting the comments. # # /etc/dovecot/dovecot.conf # !include_try /usr/share/dovecot/protocols.d/*.protocol protocols = imap lmtp pop3 dict { } !include conf.d/*.conf !include_try local.conf # eof # # /etc/dovecot/dovecot-sql.conf.ext # driver = mysql connect = host=127.0.0.1 dbname=servermail user=usermail password=changed_it default_pass_scheme = SHA512-CRYPT password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; # eof # # /etc/dovecot/conf.d/10-auth.conf # !include auth-sql.conf.ext # eof # # /etc/dovecot/conf.d/10-mail.conf # mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail # eof # # /etc/dovecot/conf.d/10-master.conf # service imap-login { inet_listener imap { port = 143 } inet_listener imaps { } } service pop3-login { inet_listener pop3 { } inet_listener pop3s { } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 user = postfix group = postfix } } service imap { } service pop3 { } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service auth-worker { user = vmail } service dict { unix_listener dict { } } # eof # # /etc/dovecot/conf.d/10-ssl.conf # ssl=required ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem # eof Thanks for making it all the way down here!

virtual mailbox segfault
by Tóth Balázs 15 Dec '14

15 Dec '14

Hello, I have a segfault problem, and I can not resolve myself. The details below (stack trace, config....). Maybe important to reproduce, everithing working well until I connect with SoGo ActiveSync (SoGo web, and other IMAP clients are working well). So maybe the SoGo send something magical command if the user client use the ActiveSyn... (the IMAP debug attached too) Thanks, Balazs Toth Program terminated with signal 11, Segmentation fault. #0 0x000002ba68e83609 in array_count_i (array=0x52d1cf10b8) at ../../../src/lib/array.h:140

[2.3 feature request]: multiple passwords for single user
by Arkadiusz Miśkiewicz 15 Dec '14

15 Dec '14

Hi. I wonder if there any plans of finishing "multiple passwords for single user" feature? Few months old thread mentioned this: http://www.dovecot.org/list/dovecot/2014-July/097217.html and even a patch that unfortunately was never finished http://dovecot.org/patches/2.0/auth-multi-password-2.0.diff Multiple passwords for single user are great since allow easy password management for users. For example you could have one password on a laptop, one on a phone, one on a tablet. Revoking access to the device is as easy as dropping single password and it doesn't affect other devices. There are more use cases. Untill that happens (not that great) workaround exists: http://wiki2.dovecot.org/Authentication/MultipleDatabases Thanks, -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Userdb's and IMAP proxying
by Thomas HUMMEL 15 Dec '14

15 Dec '14

Hello Timo, In order to plan a migration, I want to setup an IMAP proxy (proxy_maybe) with a dovecot server (I'm running the old dovecot-2.1.15 but I could upgrade or use a proxy only dovecot-2.2.x server)/LDAP pass et userdb's. I'm won't be in charge of the migration itself but I think the idea will be to migrate a chunk of users each night and then let the proxy send them to the new server. I wonder if, instead of altering my LDAP schema to be able to add the needed attributes (matching proxy/proxy_maybe, host, ...) I could use a second userdb (preferably in a file : passwd-file ?) only for those extra_fields (i.e. the second userdb would extend the LDAP one). As a matter of fact, I guess those who will migrate users will prefer writing to a file than to add some LDAP attribute in the user entry. In other words, can I get different extra_fields for the same user in different userdb's ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Groupe Exploitation et Infrastructure

Can't save to folders

When I login through imap, I can see everything in ~/mail/ just fine. I cannot save to any of them. If I have an autocreate-autosubscribe folder (ZZZ here), it shows up as empty (correct).

stacking istreams and ostreams
by Philipp Brüll 12 Dec '14

12 Dec '14

Hello, I'm developing an encryption plugin for dovecot and ran into a problem with the stacking of i/o-streams. The encryption i/o-streams are working fine on any kind of mail the test suite is passing through them. But as soon as the zlib plugin is enabled the logs show an cache error: failed: Cached message size larger than expected (214 > 206, box=INBOX, UID=1) I've already double-checked the return values of ostream's sendv and istream's read function. They seem correct (and equal). If the order of the streams are changed (by changing the number in the lib-filename libxx_scrambler.so); meaning that the encryption is done before the compression (which isn't efficient) both streams are working correct without any errors. Is there some way the zlib plugin changes the cached message size? Is there some behaviour of the zlib plugin that I'm missing? Any help would be very welcome. Best regards, Philipp -- simia.tech GbR http://simiatech.com

Dsync issues between Cyrus and Dovecot

Hello, I have some issues related with dsync when trying to perform two way synchronization between Cyrus and Dovecot. 1st time synchronization always works and email, folders, flags can be synced between these but once for example in dovecot side the user creates a folder, dsync fails with the following errors: Debug: brain M: Other brain should change mailbox INBOX/dove GUID c77e7711be9a6c77fc845ea745963ddb -> df0d180f71e38a544f9e00008aa015be Debug: brain M: out state=master_send_mailbox changed=1 Debug: brain S: in state=recv_mailbox_tree_deletes Error: Can't create mailbox INBOX/dove: Mailbox already exists INBOX/dove folder was created in Dovecot side and does not exist in Cyrus side. I have tried full sync or backup but without any luck. If I delete the folder from Dovecot side the sync works fine again. I can post more info on the configuration if needed. Thank you, Ova

PATCH - add username_format to the PAM auth module
by Bradley Kite 12 Dec '14

12 Dec '14

Hi there, Other auth modules (eg passwd-file) allow a username_format to be specified, but not the PAM module. The use-case, is where I want a static userdb configuration which takes the domain into account but still want to use PAM for authentication, eg: userdb { driver = static args = uid=8 gid=12 home=/mnt/storage/mail/vhosts/%d/%n } passdb { driver = pam args = username_format=%n allow_pam_transform=no dovecot } The global "auth_username_format" setting ends up changing the username, so looses the ability to have different mailboxes based on domain. There is also a new setting, allow_pam_transform which stops the username being changed after a successful authentication. Normally, if PAM changes the username, then dovecot must update its record of the username for further processing - but in this use case we must disable this function. -- Brad.

Error: mremap_anon(###) failed: Cannot allocate memory
by Andy Dills 12 Dec '14

12 Dec '14

We're running dovecot 2.2.15 with pigeonhole 0.4.6, in a clustered environment, nfs with proxy and backend on all servers. I've been seeing some odd errors from lmtp: Error: mremap_anon(127930368) failed: Cannot allocate memory It seems to affect specific users, but it doesn't seem to manifest in any particular way; no user complaints. Just the occasional log message. I would guess this is a bug? I'm open to suggestions and I'd be happy to post config if somebody has an idea. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

LMTP BUG
by Peter Hodur 12 Dec '14

12 Dec '14

Hello, just setting up mail hub with Postfix & Dovecot I have found BUG in LMTP implementation. * assumptions - latest stable Postix & Dovecot, - Postfix delivers via Dovecot LMTP (virtual_transport = lmtp:127.0.0.1:24), - Dovecot userdb & passwd lookups are made via custom checkpassword interface, - each user (email account) has different UID/GID * description LMTP process must run as root to be able to deliver msgs to each user. It drops privileges temporarily when delivering and then restoring effective UID/GID to root (saved one). The problem is, when an attempt with more than ONE recipients is made. More than one recipient within single session. It seems, that Dovecot LMTP restores root privileges not between each recipient delivery attempt but after whole transaction. The only solution is throttle Postfix to send single message with multiple recipients as many small transactions - all with only ONE rcpt. lmtp_destination_recipient_limit=1 makes this magic. Otherwise you can find: Dec 12 03:30:36 vm dovecot: lmtp(3580, info(a)xxx.com) Fatal: setgid(48672 from userdb lookup) failed with euid=33001, gid=43570, egid=43570: Operation not permitted (This binary should probably be called with process group set to 4867 2 instead of 43570) Can someone confirm that this is an error/bug? Thanks Pete

mdbox backup strategy
by Jiří František 11 Dec '14

11 Dec '14

Hi, now we backup maildir with rdiff-backup every single day. Backup takes almost 20hours. I would like to switch to mdbox, but how to acomplish possibility of restore emails from any date what I want? Now if I need to restore mails from the day before yesterday I put the right date to parametrs of rdiff-backup restore command and I get what I want. But if I use doveadm backup I have backup only from last run. Because we have tens of TB email I couldn't do full backup every single day. Is it possible to restore state of mailbox from backup run before the last run if I use doveadm? I don't want do full backup every day, because backup storage is not unlimited. Thank you Jiri

dovecot & Apple Mail & maildir & lots of Mail
by Thomas Klausner 11 Dec '14

11 Dec '14

Hi! I have dovecot 2.1.12 running on a mail server, and recently configured Apple Mail to connect to it using secure IMAP, for the first time. At the beginning it just showed the inbox and everything was fine, but then I wanted to look at some of my folders and found the 'subscribe' menu. When I opened it, Apple Mail went to discover what mailboxes there are, and that's where my trouble began. It seemed to make good progress for some time (though slow -- over days), and now lists the mailboxes from starting with letters a to d on the left hand side (filling all the visible space, so there might be more). However, whenever Apple Mail gets focus, the cursor becomes a spinning rainbow circle and I can't interact with it. I tried deleting the mail account and setting it up again. The inbox was shown again immediately and Apple Mail was usable, but the first time the cursor moved over the mailboxes on the left hand side, it froze again. There were two imap processes on the server, one rather idle, the other eating CPU for about two minutes, then idling, and some time later it disappeared too. My Mail directory is 31G with about 180 directories, each containing mails in maildir format. Has anyone had similar issues? Is my maildir too big for dovecot too handle? How can I debug this? Thanks, Thomas

Quota issue with mailbox.

Interpreting the last section: The transaction log records recent changes to a mailbox, and together with the index, gives the current state of the mailbox. This is an I/O optimization so that mailbox states changes are quickly updated without having to compare an entire index file with the last (in-memory?) index. For large mailboxes, this can save a lot of I/O. It may persist because updates to the indices are not done immediately (again, possibly to reduce I/O), so the current mailbox state is reflected by the index file *and* deltas in the transaction log. I suspect that you could remove the transaction logs (if you do not use dbox) and dovecot should rebuild them (or more likely, rebuild the indices). Joseph Tam <jtam.home(a)gmail.com>

Renaming directories with subdirectories over IMAP
by Зинин Дмитрий Андреевич 10 Dec '14

10 Dec '14

Hi, I¹ve a problem with renaming directories with subdirectories. In root directory I create directory named ³lvl1² with subdirectory ³lvl2² When I rename directory lvl1 to lvl1-new I get: 1. /lvl1-new with subdir lvl2 but I can use only /lvl1-new and not /lvl1-new/lvl2 2. /lvl1 with subdir lvl2 but I can use only /lvl1/lvl2 and not /lvl1 Is it a feature or a bug? If bug is there a fix? PS: CentOS 6.6 and Dovecot 2.0.9-7 from official repository with all updates. Best regards, Dmitriy

doveadm -A operations failing due to broken mdbox
by Ralf Hildebrandt 10 Dec '14

10 Dec '14

I'm using "/usr/bin/doveadm purge -A" to purge the mdboxes of my users. Unfortunately this command terminates prematurely once it reaches a defective mdbox! Is there a workaround for this? Like using doveadm to get a list of valid users and then run "doveadm purge -u" on each of those? -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Dovecot Pre-Login Scripting
by Jeremy Hayden 09 Dec '14

09 Dec '14

Hello, We are in the process of migrating users from one system that is currently not hosted by our company, to our dovecot 2.2.10 installation. We are planning on doing the dovecot dsync command for copying users mail over to the new installation, but the one snag we are running into is ensuring we are able to get the users credentials stored in our system. We are migrating the email from a Gmail ISP account to our installation as they are discontinuing their support next year. The setup is a multistep process we are hoping to accomplish. When a connection is started to our cluster, it will first check the database to see if the credentials match, if not it will verify against Gmail's servers. If the Gmail test is successful, it would pass the credentials to a script to store them for future login attempts. Once the authentication is verified and stored locally, we would run a post-login script to run dsync to copy the mail down to the new system. The problem we are running into is efficiently and appropriately hooking into the dovecot authentication process. We are unable to find anything regarding PreLogin Scripting to contrast the PostLoginScripting we are currently using, and the only other thing we are currently seeing as a possible option is running a custom authentication socket or password imap-login to a script. This seems like it would be a resource nightmare depending on the server load and are hoping for a more elegant option to be unveiled. Any other options or suggestions are welcome. We are also wondering, if we have to go with the custom authentication setup, if there are any examples out there to base our scripts off in setting it up. Thank you, Jeremy

I have a Dovecot cluster which is on separate machines from my webmail/caldav/cardav cluster, and I currently have the system setup with ssl = required. Unfortunately the caldav/cardav server I am running doesn't support STARTTLS so I was wondering if there is a way to still enforce ssl for every connection with the exception of a certain subnet, or if there is a better way to accomplish this without install a local install of Dovecot on each of my caldav/cardav servers.

Using dovecot with existing mbox hieararchy - possible?
by Chris Green 08 Dec '14

08 Dec '14

I currently use mutt to read my E-Mail on a machine which runs a postfix server to receive mail by SMTP. Mail is actually delivered to the final mbox mailboxes by a custom filtering script writtin in Python. Will dovecot happily serve mail from the existing hierarchy (obviously if I configure it right) so that I can connect using IMAP to my server machine to read mail? The mbox files are all under ~/Mail with several levels of directories in some trees. Does dovecot need any sort of notification from postfix (or my Python script) to indicate that new mail has been delivered or does it just re-scan the mbox files at intervals to see changes? -- Chris Green

sdbox and IMAP folders
by Jeff Larsen 08 Dec '14

08 Dec '14

We have just migrated from cyrus-imap to dovecot 2.2.9 on Ubuntu. By default, all our user's manually created folders appear at the same folder level as INBOX (i.e., they are next to INBOX, and not inside INBOX in a typical tree view of the folders). But on Dovecot, users are able to create new folders either parallel to INBOX or as subfolders within INBOX, which I think is going to lead to confusion for our users, especially when working from the limited UI of a smartphone client where folder hierarchy is not as easy to visualize. With cyrus, this behavior depended on the client setting for "IMAP server directory" as it is called in Thunderbird. If the setting was given the value "INBOX", then all folders were parallel to INBOX and you could not create any folder that would appear in the tree inside INBOX. With the setting empty, then all folders appeared as subfolders of INBOX. It was all or nothing. When the mail accounts were migrated to dovecot, the existing top-level user folders were created in dovecot at the same level as INBOX. We did nothing intentional to get this result. We just used cyrus2dovecot to export to maildir, then doveadm sync to convert to the final sdbox. With dovecot, when "IMAP server directory" is empty, we get the original folder tree with all folders parallel to inbox, but users are also able to create subfolders inside INBOX . We are using sdbox storage and the folder heirarchy as seen in the client tree (parallel folders and subfolders) is also reflected in the server's local file system. If we change the "IMAP server directory" setting on the client while using dovecot, then all the folders that were previously at the same level as INBOX become inaccessible, so that's not a viable option. So, my question is this: Can I replicate the cyrus behavior where INBOX subfolders are an all-or-nothing option? Or are we stuck with users (having questionable file management skills in the first place) getting lost between INBOX subfolders and top-level folders.

Missing hits when performing full-text searches
by Frerich Raabe 08 Dec '14

08 Dec '14

Hi, we're running Dovecot 2.1.7 together with Solr for efficient fulltext search. A couple of days ago we reinstalled our Solr server on a new machine. After adjusting our Dovecot setup to use the new server, it took a few days to notice that something seems fishy about our full-text search: expected hits wouldn't be shown among the search results. For instance, one of the folders (a shared, read-only folder which is basically a mailinglist archive) with about 210k messages has a plaintext mail with the text 'Amman'. However, logging into the IMAP server and issueing a . SEARCH TEXT Amman In the folder doesn't yield any hits. It seems that this happens for older mails only -- trying other keywords, we did notice hits in recent mails but not in older ones. Some caching related to the old Solr server causing issues? Debugging this further, I noticed that the above IMAP command shows this in the Solr log files: INFO: [] webapp=/solr path=/select params={fl=uid,score&sort=uid+asc&q=(hdr:"Amman"+OR+body:"Amman")&fq=%2Bbox:b68ece09e22fb9502d34010017227a26+%2Buser:""&rows=209392} hits=0 status=0 QTime=229 And indeed, something like $ curl 'http://indexer:8080/solr/select?fl=uid,score&sort=uid+asc&q=(hdr:"Amman"+OR+body:"Amman")&fq=%2Bbox:b68ece09e22fb9502d34010017227a26+%2Buser:""&rows=209392' Yields no results. However, I noticed that if I remove the 'fq=' part from the query then I get a bunch of hits. Alas, I don't know whether those are to be expected or not. Does anybody have an idea what might cause this, or what the meaning of that 'box' checksum is? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

Missing metadata on Dovecot 2.2.14, on Kolab 3.3, Centos 6.6
by Max Raafat 08 Dec '14

08 Dec '14

Hello everyone, We were trying to provision a system with Dovecot instead of another working cyrus kolab system. I am stuck with a problem with the metadata, especially when it comes to the Special Folders in Kolab 3.3, like Calenders, Tasks, etc, as well as any user created Folders. Emails work perfectly, and all the types are correct. But for example, If I try to change the type of Calenders, or create a new folder from inside roundcube and set it to type "Calenders", it stays at the default which is "mail". Therefore it causes problems, when sharing events, since they are displayed as "mail" type and not "event" type. We've tracked the problem down to the metadata not existing for special folders. A simple search only shows the default "mail" metadata, but nothing for shared folders, or special folders, etc. Here is the doveconf -n ------------------------------------------------------------------------------------------------------------- [root@m3 ~]# doveconf -n # 2.2.14: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-504.el6.x86_64 x86_64 CentOS release 6.6 (Final) imap_metadata = yes mail_attribute_dict = file:Maildir/dovecot-metadata mail_gid = 5000 mail_location = maildir:~/Maildir mail_plugins = " acl" mail_uid = 5000 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / type = shared } 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 = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { driver = shadow } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/lib/dovecot/db/shared-mailboxes.db sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = vmail user = vmail } } service dict { unix_listener dict { group = vmail mode = 0666 user = vmail } } service lmtp { executable = lmtp unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve { address = 127.0.0.1 ::1 port = 4190 } } service managesieve { process_limit = 1024 } ssl = required ssl_cert = </etc/ssl/m3.company.includingchain.crt ssl_key = </etc/ssl/m3.company.de.key userdb { driver = passwd } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = " acl sieve" } protocol lda { mail_plugins = " acl sieve" } protocol imap { mail_plugins = " acl imap_acl" } ------------------------------------------------------------------------------------------------------------ Would appreciate any help or ideas as to what I can do to fix this.

MD5-CRYPT/CRAM-MD5 vs SHA512-CRYPT/PLAIN
by ML mail 06 Dec '14

06 Dec '14

Hello, I am wondering which variant is more secure for user authentication and password scheme. Basically I am looking at both variants: 1) MD5-CRYPT password scheme storage with CRAM-MD5 auth mechanism 2) SHA512-CRYPT password scheme storage with PLAIN auth mechanism In my opinion the option 2) should be safer although it is using PLAIN auth mechanism. Of course I would always use STARTTLS and not allow unencrypted connection. What is your opinion? Best, ML

Size of array hosts, vhosts_count and modulo operation
by rub zorghy 05 Dec '14

05 Dec '14

Hi, Timo Sirainen wrote (May 19, 2010 1:50:34 am) : "When a connection from a newly seen user arrives, it gets assigned to a mail server according to a function: host = vhosts[ md5(username) mod vhosts_count ]" This hash function is it still used as it is without modification ? My another question sounds pretty innocent but I have doubts about vhosts_count. Taking two directors with three backend Dovecot as an example, the number of (v)hosts assigned for each host is "100" (default value of the vhost_count variable). I gather that the value for vhosts_count (to perform the modulo operation) and the size or length of the array (vhosts[]) in terms of number of elements are equal to 300. Thx so much. gdrub

Dovecot Director and Dovecot proxy
by rub zorghy 05 Dec '14

05 Dec '14

Hi, Dovecot Director is used to keep a temporary user -> Dovecot backend server mapping. So, Director decides which backend handles each user and the user is always redirected to the same server. All user data is stored in shared storage (NFS). The Dovecot presentation featured during this webinar <http://knowledgebase.open-xchange.com/fileadmin/user_upload/open-xchange/mi…> mentions (slide 7) a Dovecot proxy cluster (doing credentials and user info lookup) behind the LB device (F5 Big-IP) Why Dovecot Director server isn't used to perform this without Dovecot proxy ? Thus, the load balancer (F5 Big-IP) can distribute requests based on IMAP protocol to Dovecot Director cluster. Thx so much. gdrub

speed up doveadm search
by Vu Ngoc VU 05 Dec '14

05 Dec '14

Hello, I have recently migrated our mail accounts from old setup with courier-imapd to Dovecot 2. I thought that I can search quicky messages in mailboxes with doveadm because of indexes. Our users are asking (sometimes) to remove messages that they have sent wrongly. Some of them are coming from Exchange, and there is a feature in Outlook to recall (to delete) a message. So basically, they give me some infos (date, sender, subject) of message to remove. And I planned to do "doveadm search", then "doveadm fetch" and at last "doveadm expunge" on the found results. But it appears that the first run of doveadm is very slow. I don't know if it is because some indexes/caches are missing at this time. But when I run again same commands it is fast. Could you tell me if I speed up search on our maildir storage? I have no idea if I must manually (or with cron) run "doveadm index" on all our accounts because index/cache is only generated when users access their mailboxes. Or do I have to tune some settings like : mail_always_cache_fields, mail_cache_fields, mail_cache_min_mail_count, mail_never_cache_fields Thanks

mail_location maildir:~/Maildir Invalid user settings[SOLVED]
by soko.tica 03 Dec '14

03 Dec '14

Hallo list, I was having quite a hard time configuring dovecot on OpenBSD -current. The problem was default Maildir setting in 10-mail.conf, namely: mail_location maildir:~/Maildir was unable to locate user's home directory. As far as I can remember, it was the correct setting on OpenBSD-current a week or two ago. Once I figured out and changed it to mail_location maildir:/path/to/home/%u/Maildir the problem was solved. Attached are dmesg, maillog and doveconf -n output.

Unknown scheme SSHA256.HEX.b64
by grundy 02 Dec '14

02 Dec '14

I'm getting a very strange error and I'm completely mystified by it. Thank you so much for taking a look! I recently migrated some users from another dovecot server to my own, and the previous admin had the passwords in their database using the SSHA256 scheme in HEX format. All the password hashes are in my database (MySQL) with a {SSHA256.HEX} prefix, and I thought at first that they were working fine, but then I checked my logs and am seeing this: localhost dovecot: auth: Error: password(***(a)***.***): Unknown scheme SSHA256.HEX.b64 (I have replaced the email address with asterisks) I am completely flabbergasted, as I can't imagine how "SSHA256.HEX.b64" is even coming in to existence as a string. I have triple checked the database and that combination appears nowhere in it. Does anybody have any idea how that is happening? Thanks again. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Unknown-scheme-SSHA256-HEX-b64-tp50803… Sent from the Dovecot mailing list archive at Nabble.com.

disabling certain ciphers
by Will Yardley 02 Dec '14

02 Dec '14

Can you use both ssl_protocols *and* ssl_cipher_list in the same config (in a way that's sane)? ssl_protocols (>= 2.1) and ssl_cipher_list co-exist, or are they mutually exclusive? I have a Dovecot 2.2.13 system, and I tried setting: I also tried things like ssl_cipher_list = HIGH or ssl_cipher_list = HIGH:!MEDIUM:!LOW however, doing this seems to make v3 still work unless I explicitly do !SSLv3 in ssl_cipher_list in addition to disabling it in $ssl_protocols. This is different from Apache, which has similar parameters, but where disabling the protocol takes precedence. If I just do: ssl_protocols = !SSLv2 !SSLv3 I still get some ciphers that show up as "weak", e.g., | SSLv3: | ciphers: | TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA - strong | TLS_DHE_RSA_WITH_AES_128_CBC_SHA - strong | TLS_DHE_RSA_WITH_AES_256_CBC_SHA - strong | TLS_DHE_RSA_WITH_DES_CBC_SHA - weak [....] | TLS_RSA_WITH_DES_CBC_SHA - weak Is there a way to exclude these ciphers, while still keeping my config easy to parse and avoiding duplicative or deprecated configs? The behavior is also pretty strange; if I have something like one of the following, with or without $ssl_protocols set to exclude SSLv2 and SSLv3: ssl_cipher_list = HIGH:!MEDIUM:!LOW:!SSLv3 ssl_cipher_list = ALL:!ADH:!LOW:!SSLv2:!SSLv3:!EXP:!aNULL:+HIGH:!MEDIUM TLS v1.0 and v1.1 get disabled as well. I also can't seem to explicitly enable TLS 1.0 or 1.1 in $ssl_cipher_list. w

Adding extra fields from an external source
by Ian Allison 02 Dec '14

02 Dec '14

Hi, I have an existing (Open)LDAP which I'm using with dovecot and I would like to implement quotas. I have global quotas working, but I would like per user quotas similar to what is described in the wiki (http://wiki2.dovecot.org/Quota/Configuration#LDAP) My problem is that there is no obvious attribute in the schemas shipped in the RHEL/Centos 6 to hold the quota string. Is it possible to get User database extra fields from an external source? e.g. flat file or MySQL table. I would like to pull everything else from LDAP but just fill out quota_rule from a different source. I realize I could expand my LDAP but I'm wary of just importing some random schema. I've had mixed results doing that in the past (the qmail schema (http://www.zytrax.com/books/ldap/ape/qmail.html) was incompatible with my existing structure, and at the moment I'm using a hacked version of the linux quota project's LDAP schema (http://sourceforge.net/projects/linuxquota/) - I'd rather have something a bit more official). If there is a recommended schema that you guys use which is stable and works well I would like to give that a try. -Thanks, Ian.

If I get a reproducer, I'll see if I can get core dumps. The user involved had several procmail processes hung waiting for the lockfile on this mbox. Killing sendmail & dovecot, the procmails & restarting sendmail & dovecot is all that I did after the errors. It is possible that the last message delivered prior to the errors was truncated ("note the input-eof" in the trace), but this shouldn't result in a panic. I'd expect a warning, then the message truncated to whatever is there, and operations proceeding... Also, it appears that make install doesn't remove the doveadm zlib plugin, which it seems was obsoleted by http://www.dovecot.org/list/dovecot-cvs/2012-October/021796.html.

v2.2.15 - make check - Conditional jump or move depends on uninitialised value
by AMM 01 Dec '14

01 Dec '14

Hello, I am currently using Dovecot 2.2.10 on Fedora 16 - 64 bit system I had made v2.2.10 Fedora 16 rpm file using spec file from ATrpms. http://dl.atrpms.net/all/dovecot.spec It has been working well from 6 months or so. Today I tried to make v2.2.15 rpm using same spec file. But "make check" is giving following error: fatal_printf_format_fix .............................................. : ok 0 / 190 tests failed ==8834== Conditional jump or move depends on uninitialised value(s) ==8834== at 0x4F7FE99: __strspn_sse42 (in /lib64/libc-2.14.90.so) ==8834== by 0x10FCF1: test_ds_recurse (test-data-stack.c:123) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== by 0x10FCC9: test_ds_recurse (test-data-stack.c:119) ==8834== There are more similar errors after that and then rpmbuild aborts. I already saw that someone reported same error recently: http://dovecot.org/pipermail/dovecot/2014-October/098452.html But I do not know what is the right solution / patch? Can I disable "make check" safely? Its a production server so would not take any risk. Can anyone please tell what should I do? Thanks in advance. AMM

Unable to see virtual users

Hi all, I’m having issues getting Dovecot to work with AD on 2012 R2 in a test environment. Background: AD is running on dc1.ad.automaton.uk<http://dc1.ad.automaton.uk>, the domain is ad.automaton.uk<http://ad.automaton.uk>. The DNS server is running on ad.automaton.uk<http://ad.automaton.uk> and the automaton.uk<http://automaton.uk> DNS is set up correctly in the test environment in that everything resolves to the correct IP address and I can authenticate with whichever LDAP clients (ldapsearch, ApacheDS, sssd). It refuses to bind on Dovecot for some reason. aaron@mail:/var/log$ uname -a Linux mail.ad.automaton.uk 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:56:17 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux aaron@mail:/var/log$ dovecot --version 2.2.9 aaron@mail:/var/log$ dpkg -l | grep dovecot ii dovecot-core 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - core files ii dovecot-gssapi 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - GSSAPI support ii dovecot-imapd 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - IMAP daemon ii dovecot-ldap 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - LDAP support aaron@mail:/var/log/$ cat dovecot-debug.log … Nov 19 09:22:23 auth: Debug: auth client connected (pid=10345) Nov 19 09:22:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:23 auth: Debug: client passdb out: CONT 1 Nov 19 09:22:23 auth: Debug: client in: CONT 1 (previous base64 data may contain sensitive data) Nov 19 09:22:29 auth: Debug: client passdb out: FAIL 1 user=aaron.jenkins temp Nov 19 09:22:29 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:39 auth: Debug: client passdb out: FAIL 2 user=aaron.jenkins temp Nov 19 09:22:40 auth: Debug: client in: AUTH 3 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:44 auth: Debug: client passdb out: CONT 3 Nov 19 09:22:44 auth: Debug: client in: CONT 3 (previous base64 data may contain sensitive data) Nov 19 09:22:50 auth: Debug: client passdb out: FAIL 3 user=aaron.jenkins temp Nov 19 09:22:50 auth: Debug: client in: AUTH 4 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:56 auth: Debug: client passdb out: FAIL 4 user=aaron.jenkins temp (I’ve removed the base64 as it might contain passwords I actually use, if it’s important I’ll re-run it with a different password unredacted) Do you guys have any ideas on how to get it working with 2012 R2?

how to start a replication master-master correctly
by Eduardo Casarero 28 Nov '14

28 Nov '14

Hi all, I currently have one dovecot 2.2.15 working and I would like to add a second master server. If I configure the second server and enable the dsync in both servers, the sync will copy everything from A to B ? I mean, B server won't remove messages in A as it doesn't have anything in its users mailbox? The second master server will be a cold server just for contingency. Thanks

Move mail behavior
by Martin Stigge 27 Nov '14

27 Nov '14

Hi! I've recently migrated my IMAP mail setup from a server running an older Debian Squeeze with dovecot 1.2.15 to a new Debian Jessie system with dovecot 2.2.13. In the old setup, it used to be so that a mail moved from a folder to another one was marked as deleted in the originating folder (in dovecot 1.2.15). In the new setup, the mail just disappears from the originating folder (with dovecot 2.2.13). The mail arrives properly in the target folder, so that's fine. But I actually liked the old behavior. I observe this with Evolution as well as Icedove (Thunderbird) mail clients, which is why I assume that it's actually a change in the IMAP server behavior. Is it supposed to behave like that? Is there a way to configure this? Regards, Martin

2.2.15: SMTP submission server?
by Ron Leach 27 Nov '14

27 Nov '14

List, we're migrating to 2.2 from a 1.x version. There has been mention from time to time of a dovecot SMTP submission server. Last I saw was Timo suggesting this would be a 2.3 feature, but that there was already a 'basic' capability in 2.2 that, more or less, merely provided a secured/authorised SMTP submission. I haven't found anything about this in the wiki, but the feature is of interest to us. I would like to *not* have our MTA capable of being exploited as a relay (it isn't, at the moment) whereas users are logging into our dovecot from offsite using imaps with passwords. While moving to 2.2, I'd like to try to use a secure SMTP submission *separate* from the MTA so that that software, with whatever vulnerabilities or weaknesses it might have, remained locked down and could not relay, if at all possible. (Imaps with passwords means the login details are not transmitted in cleartext and, so, leak no security to an observer of the communications channel. Doubtless there are other weaknesses somewhere but, at least, when using hotel wifi, for example, there is little chance of revealing login details to a packet sniffer. It won't be perfect, there are probably other vulnerabilities, not least in the underlying OSs at each end, but the connection - which is a serious vulnerability in many places - will be as good as is practical to make it.) So, is there some kind of SMTP submission service for a logged in dovecot user, and how would a client make use of that? Is it possible to setup 2.2.15 for this? And, crucially, would the connections between the client (eg at a hotel in some unreliable location) be encrypted right from the start, not using STARTTLS, as is the case in imaps? And, just to be really demanding, could we configure its use on a non-standard port? regards, Ron

2.2.15 Panic in mbox_sync_read_next_mail()
by Hans Morten Kind 27 Nov '14

27 Nov '14

It might not be a fault in dovecot, as the user is accessing the folder locally with alpine while also running imap-sessions. However it would have been nice with a more graceful action than panic? The panic is preceeded by Error: Next message unexpectedly corrupted in mbox file PATH Panic: file mbox-sync.c: line 152 (mbox_sync_read_next_mail): assertion failed: (sync_ctx->input->v_offset != mail_ctx->mail.from_offset || sync_ctx->input->eof) At #7 in the enclosed backtrace the actual values are sync_ctx->input->v_offset = 564 mail_ctx->mail.from_offset = 564 sync_ctx->input->eof = 0 Some will recommend convertion to maildir, but with 25 years history, thousands of active users and dozens terrabytes of mboxes, we are not even considering it. hmk GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Pigeonhole, vacation being sent incorrectly
by Harry Mills 26 Nov '14

26 Nov '14

Hi, I have an issue with a vacation message in a sieve script. I can't see an error in the script itself. Pigeonhole version: 0.4.2-32 Dovecot Version: 2.2.10 The script was created by Ingo (part of the Horde suite), but I think the script is fine. The problem is that when a message is sent to the "everyone" group (and alias for every person in the organisation), vacation messages are being sent back which I believe is an error. The script is: =============================================== # Sieve Filter # Generated by Ingo (http://www.horde.org/apps/ingo/) (11/11/14, 5:20:06 pm GMT) require ["vacation", "regex", "fileinto"]; # Vacation if allof ( not exists "list-help", not exists "list-unsubscribe", not exists "list-subscribe", not exists "list-owner", not exists "list-post", not exists "list-archive", not exists "list-id", not exists "Mailing-List", not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) { if header :regex "Received" "^.*(2014) (\$.*\$ )?..:..:..

I cannot see the address for "user2(a)example.com" in any of those fields, or indeed referenced anywhere in the email. Is this a bug, or am I misunderstanding something?

imap-login segfaults when using post-login
by Nico Rittner 26 Nov '14

26 Nov '14

hello, i get these lines in syslog when using post-login within imap-login: imap-login: Fatal: master: service(imap-login): child 574 killed with signal 11 (core dumps disabled) imap[5523]: segfault at 14 ip b7556276 sp bfc1c940 error 4 in libdovecot.so.0.0.0[b7529000+d4000] these are the relevant sections i added: service imap-login { executable = imap post-login } service post-login { executable = script-login /path/to/exec } i also used /bin/true as /path/to/exec to exclude the used exec itself as the reason. same result. version is 2.2.13 on gentoo-linux. i wonder if this error is gentoo-specific (cflags/etc...) or a bug in dovecot. this behaviour can be reproduced on two other of my gentoo-machines. same configuration worked in previous versions, don't know the exact version number. thanks a lot for your suggestions. i'll also cc to the gentoo-people. nico

slow incremental indexing of maildirs with squat
by vitalif＠yourcmc.ru 26 Nov '14

26 Nov '14

Hi! I'm using Dovecot 2.1.7 on Debian Wheezy 32-bit (package version is 1:2.1.7-7+deb7u1) with maildirs. My problem is that the incremental indexing of maildirs with squat takes a very long time... I don't know if it reindexes anything, but it seems it iterates though all messages on each search query and reads them. It works fast only on successive queries within several minutes, probably because of the messages being in cache. What do you think, is it a bug? -- With best regards, Vitaliy Filippov

Shared mailboxes using SQL
by Daniel Miller 26 Nov '14

26 Nov '14

I recently tried to change from the simple file to a SQL dictionary for ACL. While the Wiki instructions seemed fairly clear I was having errors. After some further digging, and a little thinking - I read the errors and tried to infer what was happening. I have some IMAP groups configured for sharing. And I guessed the example dictionary didn't allow for them. Looking at my existing shared-mailboxes.db flat file I saw something that gave me a clue. So I added the following: map { pattern = shared/shared-boxes/group/$to/$from table = user_shares value_field = dummy fields { from_user = $from to_user = $to } } And things started working again! A suggestion that perhaps this be added to the wiki - possibly with a bit more information on the "map" sections. Also - would there be any benefit to setting up a separate SQL table for groups? -- Daniel

v2.2.14 released
by Timo Sirainen 26 Nov '14

26 Nov '14

http://dovecot.org/releases/2.2/dovecot-2.2.14.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.14.tar.gz.sig Looks like it took a bit longer to make this release after RC1 than I thought. I'm now in San Jose area for a few months and still jumping between apartments and trying to adjust to the new timezone. Some of the more important fixes since RC1: - Fixed several race conditions with dovecot.index.cache handling that may have caused unnecessary "cache is corrupted" errors. - auth: If auth client listed userdb and disconnected before finishing, the auth worker process got stuck (and eventually all workers could get used up and requests would start failing). Some of the larger changes since v2.2.13: * lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either. * "Out of disk space" errors are now treated as temporary errors (not the same as "Out of disk quota"). * replication plugin: Use replication only for users who have a non-empty mail_replica setting. + lmtp proxy: Log a line about each mail delivery. + Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports). + Rawlog settings can use tcp:<host>:<port> as the path. + virtual plugin: Don't keep more than virtual_max_open_mailboxes (default 64) number of backend mailboxes open. + SSL/TLS compression can be disabled with ssl_options=no_compression + acl: Global ACL file now supports "quotes" around patterns. + Added last-login plugin to set user's last-login timestamp on login. + LDAP auth: Allow passdb credentials lookup also with auth_bind=yes - IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks. - passdb static treated missing password field the same as an empty password field. - mdbox: Fixed potential infinite looping when scanning a broken mdbox file. - imap-login, pop3-login: Fixed potential crashes when client disconnected unexpectedly. - imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks. - lmtp proxy: The proxy sometimes delivered empty mails in error situations or potentially delivered truncated mails. - fts-lucene: If whitespace_chars was set, we may have ended up indexing some garbage words, growing the index size unnecessarily. - -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable. - quota: Quota recalculation didn't include INBOX in some setups. - Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed. - doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

Possible to adjust username used to determine the proxy destination?
by Andy Dills 25 Nov '14

25 Nov '14

I'm in a fairly standard cluster environment: shared storage, bunch of servers each acting as both proxies and backends. We do /bin/checkpassword authentication, allowing a great deal of flexibility...protection against brute force, billing mechanisms, but relevant to this issue, I have it set up to allow users to login with either their username (if they are in one of our default domains) or their email address. I'm realizing now that as a consequence of this, "joe" and "joe(a)xecu.net" are unique as far as dovecot is concerned. Users who login with just their username (and not the full email address) can get assigned to a different backend server than when they login with the full email address (which would also include LMTP deliveries). This has been happening for years, a few broken indexes here and there that seem to resolve themselves, so it hasn't been impacting the service, but I'd like to correct it properly. Is there a way to manipulate this? For example, if I moved the authentication to the proxy layer (it's currently proxy=y nopassword=y), and set $ENV{USER} to the full email address, will director use that for selection instead of the user-supplied username? I'm open to suggestions on how best to accomplish this. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

doveadm backup for all users to file system
by Jeff Larsen 24 Nov '14

24 Nov '14

The wiki says that doveadm backup supports the -A option for all users, but when I specify a file-system destination (like /tmp, or an NFS mounted folder), it just rewrites each user backup to the same location overwriting the previous user's content. You end up with just the content for the last user processed. I tried the typical %u substitution but that just created folder named '%u' and had the same overwrite problem. My userdb is LDAP which works just fine for other doveadm commands. The verbose/debug output from doveadm backup shows that it is processing every user. Example: doveadm -vD backup -A sdbox:/tmp/backup My understanding is that "doveadm backup" is just a front-end for dsync. The dsync manpage on the other hand says "dsync can currently sync only one user at a time. If you want to dsync all users, you'll need to get a list of all users and execute dsync separately..." It appears that "doveadm backup -A" is doing the iteration for me, but it's not generating individual destination paths for each user. So, is this is a documentation problem for "doveadm backup"? Or am I missing something here? Is there some secret sauce for "doveadm backup -A" that I'm not finding? If all else fails, I know I can write a script to iterate over the available users and run the backup repeatedly, but I would like to keep this as simple as possible. Thanks, Jeff

Outlook 2010 not connecting to secure POP3
by Robert Moskowitz 24 Nov '14

24 Nov '14

OK, I did not know that this user has a new computer with Outlook 2010. This SHOULD make it easier but... I have the computer right next to me, they brought it over. It is on the same LAN as this notebook. I can access my server with: openssl s_client -connect z9m9z.htt-consult.com:995 And then log the user in with the appropriate POP3 credentials. In Outlook 2010, in Advanced settings I have specified "This server requires an encrypted connection (SSL)" and it switches to port 995 (from 110). I try connecting and I get an error that "Your server does notg support the connection encryption type you have specified." The first time we tried this it installed my self-signed cert in the local cert store. Any idea on what is going on or how to get this working?

Strange repplication issues
by Bertrand Caplet 24 Nov '14

24 Nov '14

Hi, I know there are lots of questions about replication, but I searched and didn't find my question. I've got some problems with syncing. I've got 2 servers: A and B When a email arrives on server A sometimes it's not syncing in server B I think server A doesn't always notify server B there are new mails to sync. But I don't know how to fix it. And I spotted something, when it isn't syncing. The only thing to do is to send local or remote mail to server B and then it sync or do a "doveadm sync -A tcp:serverB.example:port" of course. My doveconf -n of the two servers are in attachements bellow. By the way both of my dovecot servers are v2.2.9 P.S.: I didn't test from server B to A but I think it's the same problem.

Migrate Separator and prefix
by Hanns Mattes 23 Nov '14

23 Nov '14

Hi, I'm thinking of changing the separator form "." to "/" and also to allow only folders under INBOX, changing the Prefix. I have to dovecot-servers, which are synched by the replication plugin. My idea is to switch off Server B, make the necessary config-changes, delete all user maildirs, restart the server an let replication do it's work. After that (and correcting the sieve-rules of the users if necessary), I'd stop server A, delete, restart, resync. My idea is, that this will avoid dealing with subscriptions files and change them to reflect the new INBOX-Structure. Is this going to work at all and/or is there a better way for the wanted migration? Thanks in advance Hanns

Prevent a message from be deleted but not from be moved
by Bruno Galindro da Costa 22 Nov '14

22 Nov '14

Is it possible to prevent a message from be deleted but not from be moved to another mailbox via ACL? I need this because I'm using antispam plugin with the mailtrain backend. It calls a script every time a message is moved to/from a monitored spam mailbox. But, if the user deletes a message from the spam folder, the script is executed with the option to train the antispam to consider that excluded message as a non spam. So, what I need is to prevent the user from delete a message from the spam mailbox, but I want to permit the user to move a menssage from the spam mailbox to another mailbox. -- Att.

It looks like these are not system users, so you may need to set mail_home explicitly to set up the home directory to /home/mail/%d/%u See http://wiki2.dovecot.org/MailLocation http://wiki2.dovecot.org/MailLocation/Maildir http://wiki2.dovecot.org/VirtualUsers/Home > > root@fastmail:/home/mail/a.com/a@a.com# l > total 108 > drwx------ 13 5000 5000 4096 Nov 20 22:19 ./ > drwx------ 3 5000 5000 4096 Nov 3 23:06 ../ > drwx------ 2 5000 5000 4096 Nov 20 22:07 cur/ > -rw------- 1 5000 5000 9920 Nov 21 03:25 dovecot.index.cache > -rw------- 1 5000 5000 12908 Nov 20 22:19 dovecot.index.log > -rw------- 1 5000 5000 202 Nov 10 22:35 .dovecot.lda-dupes > -rw------- 1 5000 5000 312 Nov 10 22:23 dovecot.mailbox.log > lrwxrwxrwx 1 5000 5000 23 Nov 9 12:21 .dovecot.sieve -> > sieve/managesieve.sieve > -rw------- 1 5000 5000 461 Nov 9 12:28 .dovecot.sieve.log > -rw------- 1 5000 5000 270 Nov 9 15:43 .dovecot.svbin > -rw------- 1 5000 5000 782 Nov 19 23:26 dovecot-uidlist > -rw------- 1 5000 5000 8 Nov 8 16:32 dovecot-uidvalidity > -r--r--r-- 1 5000 5000 0 Nov 3 23:06 dovecot-uidvalidity.54580a72 > drwx------ 5 5000 5000 4096 Nov 8 16:33 .Drafts/ > drwx------ 5 5000 5000 4096 Nov 8 16:33 .Junk/ > drwx------ 5 5000 5000 4096 Nov 8 18:50 .Junk E-mail/ > drwx------ 2 5000 5000 4096 Nov 19 23:44 new/ > drwx------ 5 5000 5000 4096 Nov 8 16:33 .ola ' aaaa \r/ > drwx------ 5 5000 5000 4096 Nov 8 16:33 .Sent Items/ > drwx------ 3 5000 5000 4096 Nov 9 15:42 sieve/ > -rw------- 1 5000 5000 69 Nov 10 22:23 subscriptions > drwx------ 5 5000 5000 4096 Nov 8 21:15 .subscriptions/ > drwx------ 2 5000 5000 4096 Nov 19 23:26 tmp/ > drwx------ 5 5000 5000 4096 Nov 8 21:15 .Trash/ > root@fastmail:/home/mail/a.com/a@a.com# > > > doveconf: > # 2.2.13: /etc/dovecot/dovecot.conf > # OS: Linux 3.14.23x x86_64 Debian 7.6 ext4 > auth_mechanisms = plain login > dict { > sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext > } > disable_plaintext_auth = no > listen = * > login_greeting = myserver > mail_location = maildir:/home/mail/%d/%u > mail_plugins = quota > mail_privileged_group = mail > managesieve_notify_capability = mailto > managesieve_sieve_capability = fileinto reject envelope encoded-character > vacation subaddress comparator-i;ascii-numeric relational regex imap4flags > copy include variables body enotify environment mailbox date ihave > 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 = /etc/dovecot/dovecot-sql.conf.ext > driver = sql > } > plugin { > quota = dict:User Quota::proxy::sqlquota > quota_exceeded_message = Quota exceeded (mailbox for user is full) / Conta > de destino cheia (o email de destino tem a caixa cheia) > quota_rule = *:storage=100M > sieve = ~/.dovecot.sieve > sieve_dir = ~/sieve > sieve_max_script_size = 10M > } > postmaster_address = trash(a)email.pt > protocols = imap lmtp pop3 sieve > service dict { > unix_listener dict { > mode = 0777 > } > } > service imap { > process_limit = 1024 > } > service lmtp { > inet_listener lmtp { > address = 0.0.0.0 > port = 24 > } > process_min_avail = 10 > unix_listener /var/spool/postfix/private/dovecot-lmtp { > group = postfix > mode = 0666 > user = postfix > } > } > service pop3-login { > inet_listener pop3 { > port = 110 > } > } > service pop3 { > process_limit = 1024 > } > ssl = no > ssl_cert = </etc/dovecot/dovecot.pem > ssl_key = </etc/dovecot/private/dovecot.pem > userdb { > args = /etc/dovecot/dovecot-sql.conf.ext > driver = sql > } > protocol lmtp { > mail_plugins = quota sieve > } > protocol imap { > mail_plugins = quota imap_quota > }

There are a number of funny things here. First of all, dovecot.sieve belongs in the *home* directory, not in Maildir. The home directory can be, typically, the parent directory of the Maildir. Like in: domains/example.com/user1/Maildir - the user1/ is the home directory and dovecot.sieve lives there. Would you please post your complete dovecot config (output of the command: dovecot -n) and also an example output of ls -la of your directory structure? See also http://dovecot.org/mailinglists.html

logwatch reporting

I am expecting better things with this new server, but I was use to some login information in logwatch that I am not seeing now.

You can contort the virtual plugin to fuse your user's INBOX and spam box together into a virtual INBOX: http://wiki2.dovecot.org/Plugins/Virtual (See section "Virtual POP3 INBOX") This turns the problem from a delivery problem into a reading (or presentation) problem. Seems sort of klunky though. In my opinion, your energy is better invested in converting your POP3 holdouts to IMAP. Joseph Tam <jtam.home(a)gmail.com>

spam folder and POP users
by Robert Moskowitz 21 Nov '14

21 Nov '14

I am new to actually running dovecot. I actually still use POP as I have for YEARS and thunderbird does not make it easy to convert to IMAP... My server is moving all tagged spam into the IMAP spam folder. Very nice for the IMAP users, but not for the POP users. Of course the server don't know, and the mysql database for users does not have any flags for this. Don't want my server to fill up with spam from POP users that don't know to check via IMAP. I am using roundcubemail for the webmail IMAP client. Is there any way for POP users to indicate that they do not want spam so nicely auto moved to the IMAP spam folder?

UNIX perms appear ok (ACL/MAC wrong?)
by [FnG] Lambik 21 Nov '14

21 Nov '14

Hi, I am struggling with Postfix/SASL/Dovecot-IMAP setup with ~/Maildir/ setup. Receiving the mail works fine, but viewing the mail(+listing) is failing. The setup I use is simple unix users from etc/passwd, (pam thru SASL) as I only host for a few people. The ~/Maildir folder has the ownership of the user, not mail or vmail, as I would have expected from the master.cf from Postfix, the permissions are drwx.- - - .- - - user group Maildir the {USER} and {GROUP} are the user/group of the person logging in on IMAP Can someone help me explain what is going wrong, or how I can increase debugging ? (I did the auth debugging, that was all fine) If you require more information please let me know.

how to recover mails - dovecot 2.2.13
by Götz Reinicke - IT Koordinator 21 Nov '14

21 Nov '14

Hi, I still have a messed up user account, with no mail client (appl mail, thunderbird, sogo) mails show up as expected. Folders look empty, some have something in it, but cant access the mails. My idea is, to move the users mal folder, let him regenerate the folderstructure from scratch and than reimport the old mails. Question: We use maildir. Can I just copy the "old" mails from e.g. user-backup/Maildir/curl/* to user/Maildir/curl/* Or which steps are needed? rebuilding any index or something etc ....? Thanks very much for any suggestion!

indexes with ocfs2
by Eduardo Ramos 20 Nov '14

20 Nov '14

Hi guys! I'm having performance issues with my dovecot+ocfs2 environment, so I'm thinking about some changes. Now, I have mail store and indexes stored in a iscsi-ocfs2 volume with that options: mmap_disable = yes dotlock_use_excl = yes mail_fsync = always mail_nfs_storage = yes mail_nfs_index = yes lock_method = dotlock I want to change indexes to local volume ext4 and do this: mmap_disable = no mail_nfs_index = no Could it cause some problem? Thanks.

High I/O wait with Dovecot POP3
by Frido Otten 20 Nov '14

20 Nov '14

Hello, In the past we've had 4 loadbalanced servers configured with courier pop3 and dovecot handling respectively POP3 and IMAP connections. These 4 servers have a shared NFS storage on a Netapp FAS3220 controller with SAS disks. This setup is handling 50 POP3 sessions per second without any problems. Now we're installing 6 new loadbalanced servers to do the same job on the same storage, but using Dovecot to handle the POP3 sessions instead of Courier. The IMAP sessions are already handled by those 6 new servers, but we're encountering high iowait issues when using POP3 on those servers. I've applied the hints from http://wiki2.dovecot.org/NFS but this had no improvement. The 6 new servers are quad core Intel(R) Xeon(R) CPU X3323 @ 2.50GHz, with 4 GB RAM connected with gigabit ethernet connection to the storage. The 4 old servers are single core (w/o HT) P4 2,8 GHz with 1 GB RAM. # dovecot --version 2.1.7 # /usr/sbin/dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686-bigmem i686 Debian 6.0.10 ext4 auth_cache_negative_ttl = 0 auth_cache_size = 8 k auth_mechanisms = plain digest-md5 cram-md5 login base_dir = /var/run/imap/ dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no login_greeting = Dovecot MX. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_fsync = always mail_location = maildir:/var/spool/mail/%1u/%1.1u/%u mail_nfs_index = yes mail_nfs_storage = yes maildir_stat_dirs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mmap_disable = yes namespace { inbox = yes location = prefix = separator = . type = private } namespace { list = children location = maildir:/var/spool/mail/%%1u/%%1.1u/%%u/:INDEX=/var/spool/mail/%1u/%1.1u/%u/shared/%%u prefix = shared.%%u. separator = . subscriptions = no type = shared } passdb { args = /etc/dovecot/dovecot-sql-auth.conf driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl quota = maildir quota_rule2 = Trash:storage=+25M } protocols = imap service anvil { client_limit = 4614 } service auth { client_limit = 2560 executable = /usr/lib/dovecot/auth unix_listener auth-master { mode = 0600 user = exim } user = dovecot } service dict { unix_listener dict { group = exim mode = 0660 user = exim } } service imap-login { chroot = login client_limit = 2048 executable = /usr/lib/dovecot/imap-login inet_listener imap { address = *, :: port = 143 } inet_listener imaps { address = *, :: port = 993 } process_limit = 2048 process_min_avail = 3 service_count = 0 user = dovecot vsz_limit = 128 M } service imap { executable = /usr/lib/dovecot/imap process_limit = 2048 } service managesieve-login { chroot = login client_limit = 2048 process_limit = 2048 process_min_avail = 3 service_count = 0 user = dovecot vsz_limit = 128 M } service managesieve { process_limit = 2048 } service pop3-login { chroot = login client_limit = 512 inet_listener pop3 { address = 1.2.3.4 port = 110 } inet_listener pop3s { address = 1.2.3.4 port = 0 } process_limit = 512 process_min_avail = 3 service_count = 0 user = dovecot vsz_limit = 128 M } service pop3 { process_limit = 2560 } ssl_cert = </etc/ssl/certs/wildcardcertificate.crt ssl_key = </etc/ssl/private/wildcardcertificate.key syslog_facility = local7 userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql-auth.conf driver = sql } protocol imap { mail_plugins = quota imap_quota acl imap_acl } protocol pop3 { pop3_uidl_format = %v.%u } protocol lda { auth_socket_path = /var/run/imap/auth-master info_log_path = /var/log/dovecot-deliver.log log_path = /var/log/dovecot-deliver.log mail_plugins = sieve quota postmaster_address = Mailer-Daemon(a)mx.domain.nl rejection_reason = Your message with subject "%s" was automatically rejected:%n%r sendmail_path = /usr/sbin/exim } Best regards, Frido

redis dict auth and default_fields
by brd 20 Nov '14

20 Nov '14

Hi all, i'm trying to configure default_fields with redis dict (allow_nets, proxy, ...) but it seems that the properties defined are not used even if they appear on output of doveconf. It is a known behaviour? Does default_fields works only for ldap db? I have a director+NFS environment and with dict passdb i'have to put proxy=y for every entry in pass/userdb; to limit the redis memory footprint it should be cool if the proxy=y can be configured as a default_field. It is a limit of using dict for pass/userdb cause using SQL you can manage it as a SELECT fixed field, using LDAP you can manage with default_fields but with dict you are forced to put all inside the db entries. doveconf output: [...] passdb { args = /etc/dovecot/dovecot-dict-auth.conf.ext default_fields = proxy=y driver = dict } [...] Regards -brd

Dovecot auth process repeatedly crashes on OS X Server 10.9
by James Reynolds 20 Nov '14

20 Nov '14

My dovecot/auth process crashes several times a minute, sometimes at the same second, sometimes randomly. I’ve turned on auth_debug and been pouring over everything trying to see if I can see what is going on but I can’t find anything. I’m running OS X Server 10.9 and dovecot 2.2.5. I can’t say for sure, but it looks to me like the crashed process doesn’t even save anything to mail-debug.log before it crashes. It takes about 2 seconds for it to come up. Once it crashed about 10 times in 2 seconds. Can anyone give me any ideas where I should look? Here are relevant portions from logs: mail-info.log Nov 06 17:19:10 pop3-login: Info: Aborted login (auth process communication failure): user=<>, method=DIGEST-MD5, rip=155.101.106.229, lip=10.0.0.128, TLS mail-err.log Nov 06 17:19:10 pop3-login: Warning: Auth connection closed with 1 pending requests (max 0 secs, pid=66114, EOF) Nov 06 17:19:10 auth: Fatal: master: service(auth): child 66100 killed with signal 11 (core dumps disabled) It looks exactly like what is discussed here: https://discussions.apple.com/thread/6482632?start=0&tstart=0 I do have clients using Outlook.

Handle of "subscription" file/folder for IMAP
by Jorge Bastos 19 Nov '14

19 Nov '14

Hi, For IMAP users, there's the subscription file in the user's home, and if I try to subscribe more imap folders that are invisible, there's that one, but as it is a file, nothing is supposed to happen. Is there an way to, allow users to create the "subscriptions" folder without any collision, or just deny or don't show this file as an possible folder (which Is not) to subscribe. What does people normally do? Thanks in advanced,

Storage IOPs Calculation for Qmail Server
by SasiKumar.K 19 Nov '14

19 Nov '14

Dear DovecotORG, In my organization, we are about to implement Qmail Server. * The number of current users will be 800, in future it may increase upto 1200. * The number of concurrent users will be 300. I am the engineer to deploy the Qmail in Linux server. I need to tell the storage team on the IOPs requirement. I requested 8TB usable space for the mail storage (can scale up in future). Kindly provide your suggestion on this. Thanks & Regards, K.SasiKumar Systems Engineer, Locuz Enterprise Solutions Limited, Bangalore

userdb-nss crash

Hi All. I have a some problem with dovecot, when I try to use nss in auth userdb. nss was setup to resolve users and group by winbind. nss and winbind works well, command "id user" shows remote user's info. I would like to use nss userdb, but dovecot crashes on start. Is this a bug or incorrect settings?

custom ssh port doveadm sync
by dvm＠rdyn.net 18 Nov '14

18 Nov '14

Hi all, First sorry i really couldn't find it back been searching everywhere even the docs and its bit confusing. I am using # doveadm -D sync -u *(a)mydomain.net remote:myserver.net # which works perfect however for security reasons we now need to change the sshd port on the remote server. How do i tell doveadm to use a custom SSH port (would love to continue to use just the ssh connection), if anyone could explain that would be great, because all i found is custom tcp or tcp ssl which is not what we want to use, as i wish to stick with custom ssh port. Regards, r. -- This email was Virus checked by UTM 9. http://www.astaro.org

Different SSL certificates per IP and protocol
by tree 18 Nov '14

18 Nov '14

Hi Dovecot Users and Developers, I am hosting the server with multiple domains. I have setup the dovecot with the instructions from http://wiki2.dovecot.org/SSL/DovecotConfiguration Each domain has it's own ip address. However, when I connect via Thunderbird or any other mail clients, the client is ONLY picking up the top-level "default" ssl_key and ssl_cert and the certificat in /etc/ssl/dovecot.pem Is this a bug? This is on Debian Wheezy. Any help pointing in the right direction would be appreciated thanks. Here is the ssl section: ----------- ssl_cert = </etc/ssl/dovecot.pem ssl_key = </etc/ssl/dovecot.pem local 192.0.2.10 { # instead of IP you can also use hostname, which will be resolved protocol imap { ssl_cert = </etc/ssl/dovecot/imap-01.example.com.cert.pem ssl_key = </etc/ssl/dovecot/imap-01.example.com.key.pem } protocol pop3 { ssl_cert = </etc/ssl/dovecot/pop-01.example.com.cert.pem ssl_key = </etc/ssl/dovecot/pop-01.example.com.key.pem } } local 192.0.2.20 { protocol imap { ssl_cert = </etc/ssl/dovecot/imap-02.example.com.cert.pem ssl_key = </etc/ssl/dovecot/imap-02.example.com.key.pem } protocol pop3 { ssl_cert = </etc/ssl/dovecot/pop-02.example.com.cert.pem ssl_key = </etc/ssl/dovecot/pop-02.example.com.key.pem } } -----------------------

Mail sync at filesystem level
by Cédric Jeanneret 18 Nov '14

18 Nov '14

Hello, I'm currently building a mail infra using some decentralized filesystem for the storage. As I'm wanting to get multiple "entry-points" (servers running dovecot + postfix + other mail-related stuff), all of them sharing the same storage (most probably xtreemfs), how will dovecot cope in this case? As I see things: server1 gets a mail for User1; it pushes it to the xtreemfs directory. server2 shares the same xtreemfs directory, thus it can access the same mail listing User1 connects to server2: will he see the new mail? Will dovecot on server2 know about it? Thanks! Cheers, C.

Understanding why Dovecot unexpectedly died
by Luca Bertoncello 18 Nov '14

18 Nov '14

Hi list! I use Dovecot 1.2.17 (I can't upgrade right now, due to many reasons), controlled by Pacemaker (I have an HA-Cluster). Now I see that Pacemaker restarts often Dovecot. I wrote my own script to manage Dovecot, since Pacemaker does not have his own. My script, by the "monitor" section has this: monitor) if [ ! -e $OCF_RESKEY_pid ]; then echo "stopped (no pidfile)" echo "DOVECOT STOPPED - NO PIDFILE" | /usr/bin/logger -p local0.info -t DOVECOT-MONITOR -i exit $OCF_NOT_RUNNING else /bin/ps axuwf | /bin/grep `/bin/cat $OCF_RESKEY_pid` | /bin/grep -v grep > /dev/null 2>&1 if [ $? -ne 0 ]; then echo "stopped" echo "DOVECOT STOPPED - NO PROCESS" | /usr/bin/logger -p local0.info -t DOVECOT-MONITOR -i exit $OCF_NOT_RUNNING else if [ "`/bin/netstat -tupan | /bin/grep dovecot | /bin/grep $OCF_RESKEY_bindaddr | /usr/bin/wc -l`" -ne 0 ]; then exit $OCF_SUCCESS else echo "DOVECOT STOPPED - NO LISTEN [`/bin/netstat -tupan | /bin/grep dovecot`]" | /usr/bin/logger -p local0.info -t DOVECOT-MONITOR -i exit $OCF_ERR_GENERIC fi fi fi exit $OCF_SUCCESS ;; The "loggers" was added now to try to understand why it dies... Well, I can see in my syslog, when Pacemaker restarts Dovecot, these lines: ov 15 18:59:09 mail01 DOVECOT-MONITOR[530]: DOVECOT STOPPED - NO LISTEN [tcp 0 0 192.168.33.1:37545 192.168.33.3:3306 ESTABLISHED 637/dovecot-auth Nov 15 18:59:09 mail01 DOVECOT-MONITOR[530]: tcp 0 0 192.168.33.1:37537 192.168.33.3:3306 ESTABLISHED 529/dovecot-auth] So, there is no "dovecot"-Process listening anymore... Normally I have these: tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN 634/dovecot tcp 0 0 192.168.33.1:40994 192.168.33.3:3306 VERBUNDEN 891/dovecot-auth tcp 0 0 192.168.33.1:40984 192.168.33.3:3306 VERBUNDEN 638/dovecot-auth tcp6 0 0 :::110 :::* LISTEN 634/dovecot tcp6 0 0 :::143 :::* LISTEN 634/dovecot tcp6 0 0 :::993 :::* LISTEN 634/dovecot tcp6 0 0 :::995 :::* LISTEN 634/dovecot In the mail.log and mail.err I can't see anything but: Nov 15 18:59:13 mail01 dovecot: Dovecot v1.2.17 starting up Nov 15 18:59:13 mail01 dovecot: auth-worker(default): mysql: Connected to 192.168.33.3 (exim) And in the syslos there is nothing about Dovecot... Any idea? Thanks a lot! Luca Bertoncello (lucabert(a)lucabert.de)

LMTPS : TLS over LMTP not working
by Stanislas SABATIER 17 Nov '14

17 Nov '14

Hello, I tried to activate SSL on LMTP service, to secure connections between Postfix and Dovecot on my LAN, but Dovecot is not negociating a TLS session with Postfix. If I enforce TLS for LMTP at Postfix's side, communication between Postfix and Dovecot is not working. I put ssl = yes ssl_cert = </dovecot/ssl/ssl-LMTP.pem ssl_key = </dovecot/ssl/ssl-LMTP.key in section protocol LMTP within 20-lmtp.conf and service lmtp { inet_listener lmtp { name = dovecot_lmtp address = xx.xx.xx.xx port = 26 ssl = yes } process_min_avail = 5 } within 10-master.conf Did I miss something ? Thank you for your help. Regards, Stan

inbox parameter is ignored within location config for public namespaces?
by Dieter Knopf 17 Nov '14

17 Nov '14

Hello, i already asked a similiar question some month ago but still have no fix for my problem :-( This is my global location option in 10-mail.conf: mail_location = maildir:/home/vmail/%d/%n/MAILDIR:INBOX=/home/vmail/%d/%n/MAILDIR/.INBOX:INDEX=/home/vmail/%d/%n/INDEX/ This works fine, until i'm using a public namespace. The following namespace is a normal user too, every mail to bos(a)foo.eu is stored in /home/vmail/foo.eu/bos/MAILDIR (within the INBOX-folder) and this directory is used for the location of the namespace. Config: namespace { type = public separator = / prefix = BOS/ location = maildir:/home/vmail/foo.eu/bos/MAILDIR:INBOX=/home/vmail/foo.eu/bos/MAILDIR/.INBOX:INDEX=/home/vmail/foo.eu/bos/S_INDEX:INDEXPVT=/home/vmail/foo.eu/bos/S_INDEXPVT/%u subscriptions = yes } The namespace itself works fine and without a problem, but the INBOX folder is the main problem. Mail users agents like Thunderbird now shows a folder structure like: BOS (grey, not useable) - INBOX (the .INBOX folder) - Other folder 1 - Other folder 2 - Other folder 3 The INBOX-config works fine for every single user, but it don't work on namespaces? Is this a bug? Thanks Dieter

A6 Yes, but be aware of the following point. A file descriptor is a reference to an open file description (see open(2)). Whenever a descriptor is duplicated via dup(2), dup2(2), fcntl(2) F_DUPFD, or fork(2), a new file descriptor referring to the same open file description is created. An open file description continues to exist until all file descriptors referring to it have been closed. A file descriptor is removed from an epoll set only after all the file descriptors referring to the underlying open file description have been closed (or before if the descriptor is explicitly removed using epoll_ctl() EPOLL_CTL_DEL). This means that even after a file descriptor that is part of an epoll set has been closed, events may be reported for that file descriptor if other file descriptors referring to the same under‐ lying file description remain open. So the close(11) should be enough to remove the fd 11 from epoll(10) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBVGNvlHz1H7kL/d9rAQKYcAf/dJKQGFqi8wZBwG1GevEc+DYJeZYGSUxB YOtMV+szUrVyl+vD0GZNyXKotO6/xn0gipeV1tLTZ1xIg7NIsVcJ2/DC1WENenrE YePmuuX/TQNpj7nOcQiATFtOtenqV9itwm5zrhTN1vzjyVbEnPwhVjsaOAnaUk9u HN/BdxTazDd7QTEQmJNMKJBFyg/Im0ktJpo/eAKuysv/mcZ9HOorTQhtocK7Goro YqOWacuEZVA0TUtD1hqDn9OfvEymp0oPoM8gEYON7lK4OQ9d6+hWMpkH5BG5x+7Z ZPmq9xUJW17tcbe2imKkXw+RBRNofgf5GyhMwNVoLhbOKa29tYWqXw== =yIiy -----END PGP SIGNATURE-----

Optional mail attribute in ldap
by Alexandros Soumplis 17 Nov '14

17 Nov '14

Hello, I am using an ldap database (active directory) for dovecot authentication and I am trying to change the mail location for some users only, thus any mail should be delivered to the default location unless the ldap query returns a successful result which defines the mail variable. I have chosen the AD atttribute "otherMailbox" and added for the required user the value "=mail=mdbox:/newmailboxes/%Lu/". It seems not to work and mails still get delivered to the default location. Any suggestions ? a.

Understanding filesystem quotas
by Chris Szilagyi 15 Nov '14

15 Nov '14

Hello: I've been trying to set up filesystem quotas for IMAP, and cannot seem to get it to work. In IMAP clients it either shows quota unavailable or unknown. I've read the documentation several times. I've enabled the quota plugins and to my knowledge that part is good. I've edited the file 90-quota.conf and uncommented these lines and set them as follows: plugin { quota_rule = *:storage=1G } plugin { quota = fs:User quota:user } To my knowledge, this should enable filesystem quotas by user. However when I run "doveadm quota get -u username", it shows: Quota name Type Value Limit % User quota STORAGE 0 - 0 So basically all zeros. I've also tried running "doveadm -Dv quota get -u username" and don't see anything that stands out or that would indicate an issue. It shows the correct block device and such. I know filesystem quotas are working as I can run "quota username" and it shows the usage. The reason I picked filesystem quotas is because we have /var/spool/mail/username (spool file), and /home/username/mail on the same partition, and because it sounds like it's fast and doesn't require disk I/O. But I'm trying to also figure out by setting the "storage=" command in Dovecot, do I even need to set a hard and soft limit on the filesystem quota then? I would prefer to let Dovecot enforce quotas rather than rely on the filesystem quota mechanism, but keep disk I/O down. Any help would be greatly appreciated on this. Thank you. -- Chris

Using dovecot-lda with sendmail
by Chris Szilagyi 15 Nov '14

15 Nov '14

Hello: I'm trying to get dovecot-lda to work with sendmail on a CentOS 7 server. I've tried following the instructions at the wiki, http://wiki2.dovecot.org/LDA/Sendmail, by adding the lines to /etc/mail/sendmail.mc, recompiling to /etc/mail/sendmail.cf and restarting sendmail -- the process for any sendmail config change. However it is still not working and in the maillog, it shows: sendmail[31949]: sAEM4GTt031742: to=<user@localhost>, ctladdr=<test@localhost> (1000/1000), delay=00:08:31, xdelay=00:00:00, mailer=local, pri=210942, dsn=4.0.0, stat=Deferred: local mailer (/usr/libexec/dovecot/dovecot-lda) exited with EX_TEMPFAIL I verified that SELinux is not interfering in this case. I see talk of having sendmail run /usr/libexec/dovecot/dovecot-lda as other users, but I see that the file on my system is uid/gid as: root/root. Is there a way to get this working? Thanks much! -- Chris

Evolution clientware and Dovecot
by The Doctor 14 Nov '14

14 Nov '14

Got a customer using Evolution 2.12.3 and was using SSL and could not retrieve e-mail in the last week. Got the custome to turn off SSL and he was able to retrieve e-mail. Recently I compiled SSL so that any comprimise was removed and then all apps using SSL including dovecot was recompiled. Could this be an app/Evolution issue? -- Member - Liberal International This is doctor@@nl2k.ab.ca Ici doctor@@nl2k.ab.ca God,Queen and country!Never Satan President Republic!Beware AntiChrist rising! http://www.fullyfollow.me/rootnl2k Look at Psalms 14 and 53 on Atheism Lest we forget 2014

Dovecot wiki LMTP description
by Ron Leach 14 Nov '14

14 Nov '14

List, we are planning a new configuration to which we'll migrate an existing installation shortly. We are hoping to use Dovecot LMTP and have a query about the wiki entry for LMTP http://wiki2.dovecot.org/LMTP where it suggests this config: service lmtp { inet_listener lmtp { address = 192.168.0.24 127.0.0.1 ::1 port = 24 } Does this example mean that LMTP will only listen for input messages from the interface with IP address 192.168.0.24 (plus localhost)? If so, I probably haven't understood how LMTP is intended to work. Is there a reason why we want to limit LMTP to listening for messages from a specific IP on the network? I need to understand that so that I replace ...24 with a suitable host interface that exists on our LAN (we don't have a host at 192.168.0.24). Apologies for what must seem, to people using LMTP, a very basic question. Nevertheless, I would be grateful for any clarification. regards, Ron

Dovecot Cur and New Directories are empty
by Nguyen Dinh Phuoc Thanh 14 Nov '14

14 Nov '14

Hi, Recently, we faced an issue with dovecot.

automatically create Spam mailbox
by Cliff Hayes 14 Nov '14

14 Nov '14

I am trying to set up dovecot to automatically create a Spam mailbox for every user. http://wiki2.dovecot.org/MailboxSettings shows how to do this but not what config file to put it in so I assume 10-mail.conf. When I put it in there as follows... namespace inbox { mailbox Spam { auto = create special_use = \Junk } } ... I get the following error ... doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-mail.conf line 107: Unknown setting: mailbox How do I create the mailbox?

Core Dump upon startup (SEGV) - v2.2.10

In my recent messages I mentioned how I was having difficuilty in making my wife's email readable in Squirrelmail; this was solved with directory permissions. However, my usual email client is Thunderbird; I was holding off on using that as there appeared to be authentication issues. Today was my opportunity to start debugging those; it occurred to me that I might have issues with PKI and tried to make/install working certificates. When this didn't work, I though to just scrub the installation and start over. On my CentOS 7 system I erased and reinstalled from RPM. With what should have been working certificates, I ran through the config files, and then restarted to the following error: [root@dungeon dovecot]# systemctl -l status dovecot.service dovecot.service - Dovecot IMAP/POP3 email server Loaded: loaded (/usr/lib/systemd/system/dovecot.service; disabled) Active: failed (Result: core-dump) since Thu 2014-11-13 19:05:52 EST; 30min ago Process: 23700 ExecStart=/usr/sbin/dovecot -F (code=dumped, signal=SEGV) Process: 23695 ExecStartPre=/usr/libexec/dovecot/prestartscript (code=exited, status=0/SUCCESS) Main PID: 23700 (code=dumped, signal=SEGV) Nov 13 19:05:52 dungeon.the-leveys.us systemd[1]: Started Dovecot IMAP/POP3 email server.

Migrate system users to virtual users
by Ron Leach 13 Nov '14

13 Nov '14

List, good afternoon, We are at the planning stage of wanting to migrate from an existing installation onto a new machine, and also to change from system users to virtual users. May I check that our ideas for user id are correct? I am not sure whether we will encounter a 'permissions' and 'user id' problem when moving from a system-user scheme to a virtual scheme. We use Maildir, and the maildirs at the moment are in their users' linux /home directories. After reading the wiki, we think that the 'single system user for vmail' arrangement, ie just one system user to manage all the mail for all virtual users, will work for us. I think that means that the permissions on all our existing 'system-user-oriented' maildirs will have to be changed (in the new machine) so that they are owned by the 'single-system-user', such as 'vmail'. One thought was to first copy the existing maildirs into the new virtual user file system tree, and then, second, change the owners and permissions on the maildirs and directories and messages to permit control by 'vmail'. From the point of view of transferring all the mail files, is that all we would have to do? (Of course, we would also have to create the virtual users and their passwords, and arrange the appropriate password lookups etc, but that's not the direct topic of this post. And that arrangement has to be compatible with the MTA, as well.) If we do copy the maildirs and change the permissions, does all the metadata that the clients, or Dovecot, use to detect new, existing, or downloaded mail remain valid? Or should we use a different approach? Grateful for any comment regards, Ron

Bug (?) while listing imap folder

Dear All, I think I've hit a bug after migrating our mail server to the newest version of dovecot (version 2.2.15). When I try to list all imap folders for one user the imap process crashes. The listing to a specific folder (ex. INBOX) works fine, only the "*" crashes. Client side: --------------------- [root@mb log]# telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to 127.0.0.1.

Hi, after upgrade to Dovecot >= 2.2.14rc1 sometimes I found this error/crash in the log (never happened with 2.2.13), I'm the only one? Can be fix? Nov 11 17:44:26 imap(info(a)myemail.com): Error: Corrupted transaction log file /home/domains/myemail.com/info/Maildir/dovecot.index.log seq 190: Invalid transaction log size (32756 vs 32772): /home/domains/myemail.com/info/Maildir/dovecot.index.log (sync_offset=32756) Nov 11 17:44:26 imap(info(a)myemail.com): Error: Log synchronization error at seq=0,offset=0 for /home/domains/myemail.com/info/Maildir/dovecot.index: Append with UID 10777, but next_uid = 10778 Nov 11 17:44:26 imap(info(a)myemail.com): Error: /home/domains/myemail.com/info/Maildir/dovecot.index view syncing failed to apply changes Nov 11 17:44:26 imap(info(a)myemail.com): Panic: file index-sync.c: line 265 (index_mailbox_sync_next_expunge): assertion failed: (range->seq2 <= ctx->messages_count) Nov 11 17:44:26 imap(info(a)myemail.com): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x75e1a) [0x7fbbd213ae1a] -> /usr/lib/dovecot/libdovecot.so.0(+0x75e96) [0x7fbbd213ae96] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7fbbd20ec2bf] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb219c) [0x7fbbd245719c] -> dovecot/imap(imap_sync_more+0xc3) [0x41fd13] -> dovecot/imap() [0x420437] -> dovecot/imap(cmd_sync_delayed+0x209) [0x4208f9] -> dovecot/imap(client_handle_input+0x1ed) [0x4178dd] -> dovecot/imap(client_input+0x6f) [0x417b9f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x5b) [0x7fbbd214c0db] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xaf) [0x7fbbd214d27f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7fbbd214c169] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fbbd214c1f8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fbbd20f1193] -> dovecot/imap(main+0x2b0) [0x4210d0] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7fbbd1d81cad] -> dovecot/imap() [0x40bea9] Nov 11 17:44:26 imap(info(a)myemail.com): Fatal: master: service(imap): child 13586 killed with signal 6 (core dumped) # gdb /usr/libexec/dovecot/imap /home/domains/myemail.com/info/core Reading symbols from /usr/libexec/dovecot/imap...done. warning: Can't read pathname for load map: Input/output error.

Query: SELECT "INBOX" permission denied
by Don Levey 12 Nov '14

12 Nov '14

Yesterday I was forced to migrate servers due to a hardware failure. I have been able to bring up my mail server, and set up Squirrelmail and Dovecot. I am able to access (via Squirrelmail) all users' mail except one - which happens to be my wife's, so it would be really helpful if I could get that working too. I am able to log in, but see the following message in the main pane: ERROR: Could not complete request. Query: SELECT "INBOX" Reason Given: [NOPERM] Permission denied I have see similar errors in my searches, but they all relate to *creating* files (inbox, sent, etc). The files do already exist here, they used to work in the same directory structure on the old server configuration, and I can see no relative difference between this user's files/permissions and working users' files/permissions. Suggestions are welcome; thanks in advance, -Don Here are the vitals: Version: 2.2.10 OS: CentOS 7 # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-123.9.3.el7.x86_64 x86_64 CentOS Linux release 7.0.1406 (Core) ext3 auth_mechanisms = plain login disable_plaintext_auth = no log_path = /var/log/dovecot.log mail_location = mbox:/home/%u/~mail:INBOX=/var/spool/mail/%u mbox_write_locks = fcntl 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 } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } [root@dungeon sandra]# ls -la /var/spool/mail total 2097152 drwxrwxr-x. 2 root mail 4096 Nov 11 22:10 . drwxr-xr-x. 16 root root 4096 Nov 11 14:21 .. -rw-rw----. 1 sandra mail 625547161 Nov 11 21:32 sandra -rw-rw----. 1 spamtrap_000 mail 26773946 Nov 11 20:53 spamtrap_000 -rw-rw----. 1 spamtrap_001 mail 3092961 Nov 11 22:10 spamtrap_001 -rw-rw----. 1 spamtrap_002 mail 8778257 Nov 11 00:03 spamtrap_002 -rw-rw----. 1 spamtrap_003 mail 63579856 Nov 11 21:21 spamtrap_003 Her directory: [root@dungeon .imap]# ls -la total 100 drw-------. 25 sandra sandra 4096 Jul 1 2008 . drwx------. 4 sandra sandra 4096 Nov 10 10:48 .. drwx------. 2 sandra sandra 4096 Jul 1 2008 bday drwx------. 2 sandra sandra 4096 Jul 1 2008 beads drwx------. 2 sandra sandra 4096 Jul 1 2008 books drwx------. 2 sandra sandra 4096 Jul 1 2008 Drafts drwx------. 2 sandra sandra 4096 Jul 1 2008 ham drwx------. 2 sandra sandra 4096 Nov 11 21:39 INBOX drwx------. 2 sandra sandra 4096 Jul 1 2008 Sent drwx------. 2 sandra sandra 4096 Jul 1 2008 spam drwx------. 2 sandra sandra 4096 Jul 1 2008 Trash drwx------. 2 sandra sandra 4096 Jul 1 2008 Work A working directory: [root@dungeon .imap]# ls -la total 56 drwx------. 14 spamtrap_003 spamtrap_003 4096 Oct 23 19:22 . drwx------. 3 spamtrap_003 spamtrap_003 4096 Nov 10 09:15 .. drwx------. 2 spamtrap_003 spamtrap_003 4096 Jun 8 08:40 Deleted Messages drwx------. 2 spamtrap_003 spamtrap_003 4096 Aug 11 2011 Drafts drwx------. 2 spamtrap_003 spamtrap_003 4096 Mar 18 2011 ham drwx------. 2 spamtrap_003 spamtrap_003 4096 Nov 11 21:21 INBOX drwx------. 2 spamtrap_003 spamtrap_003 4096 Oct 18 2013 Sent drwx------. 2 spamtrap_003 spamtrap_003 4096 Aug 28 09:55 Sent Messages drwx------. 2 spamtrap_003 spamtrap_003 4096 Oct 6 20:11 spam drwx------. 2 spamtrap_003 spamtrap_003 4096 Nov 11 21:21 Trash

I am using dovecot in mbox format. I'm going to set to leave the 30-day mail to the server with the mail client. The other day, some of email was received duplicate When receive mail.

Disabling SSLv3 protocol
by Timo Sirainen 12 Nov '14

12 Nov '14

Since people are now talking about the SSLv3 security hole and how to disable it, here's a thread where you can talk about that. In Dovecot v2.1+ you can disable SSLv3 by setting: ssl_protocols = !SSLv2 !SSLv3 In older versions you'd have to patch the source code. Attached a patch against v2.0. I don't know if there are any clients that would break by disabling SSLv3. I'd expect all the clients to use the system (or otherwise generic) SSL libraries, which would automatically choose the TLS protocol over SSL. So my guess is that unless somebody is using over a 10 year old client there wouldn't be any problems. Maybe some old mobile phones might be using SSL.. If you find out about any clients that require SSLv3 I'd like to know about it. For Dovecot v2.3 I could maybe disable SSLv3 by default if there's no real need for it. (Also: Don't be confused by SSL/TLS protocols vs. SSL port/STARTTLS, as described in http://wiki2.dovecot.org/SSL. For example https://en.wikipedia.org/wiki/Comparison_of_email_clients#SSL_and_TLS_suppo… is irrelevant here.)

New director features
by Timo Sirainen 12 Nov '14

12 Nov '14

I implemented a couple of larger director changes today. These could still be changed a bit if somebody has any ideas. http://hg.dovecot.org/dovecot-2.2/rev/b9df3d654710 Support for director "tags", which allow creating multiple Dovecot backend groups using a single director ring. So you can mark different backend hosts with @tag names and then have passdb lookup return the wanted tag for each user. Note that because director works using user hashes, two users with the same hash can't be in different backend groups. Use "doveadm director map -u user@domain" to see which hash is used by the user@domain. http://hg.dovecot.org/dovecot-2.2/rev/b9df3d654710 Added director_consistent_hashing=yes setting so users don't move around much when backend servers are added/removed. Ideally at some point this setting will be removed and directors will automatically switch to it when all the directors in the ring support it.

FTS-Solr: indexer-worker does not find mailbox
by Marc Stürmer 11 Nov '14

11 Nov '14

Greetings, I am running Dovecot v. 2.2.13 on a Gentoo Box. Mail users are virtual, data for them is stored in a MySQL-DB, Sieve is enabled and deliver is the LDA in conjunction with Postfix. This setup has been running for a few years now without problems, the configuration works. Some weeks ago the setup was still on a Ubuntu 12.04 LTS box, and Dovecot was v. 2.0.9. I've installed a Tomcat there with Solr and configured the FTS-Solr plugin from Dovecot. Worked like a charm without any problems at all. Now the same setup on the Gentoo box does not work at all; either indexer-worker does not find the directory or is just indexing 0 messages. Solr is also installed again (v. 3.6.0) on Tomcat, and Solr is running properly. I checked it with my browser and the logs, they are showing no errors. gentoo ~ # dovecot --version 2.2.13 dovecot -n: http://pastebin.com/NqLfrbp8 dovecot-sql.conf: http://pastebin.com/KLf4pjJZ Debug log.

Virtual User Authentication
by Jerry 11 Nov '14

11 Nov '14

I have only "virtual users" on the system that I maintain. I am using Postfix which is configured to use Devecot for authentication. I get several attempts everyday to hack into the system, both via Postfix and directly via Dovecot. The following is from the dovecot log: Nov 11 04:14:48 auth-worker(21005): Error: pam(monica,69.193.88.146): pam_authenticate() failed: authentication error (/etc/pam.d/dovecot missing?) Now, I do not use "pam" on this system. Is there a way I can eliminate Dovecot from trying to use it? -- Jerry

Replication Advice Needed
by Asai 11 Nov '14

11 Nov '14

I successfully set up Dovecot replication, having 2 servers syncing with each other. While I had both servers in the same room on a Gigabit network, they were syncing fine. But I took one to another location, and syncing was turned off for about 2 weeks. Now I've turned both back on, they're sort of syncing, but not really. The one remote server is not populating emails into various folders and it really should be cranking to sync those emails. Do anyone have any insights on how we could troubleshoot this? -- --Asai

deliver an email to a large number of local users directly via doveadm
by Mahdi Mahdi 11 Nov '14

11 Nov '14

Hello,We have a mail service that uses postfix and dovecot. We would like to send an email to a large number of users(about 100K). However, it takes too long to send the email through smtp. Is there any solution to deliver the email locally to all user mailboxes directly.dovecot uses lmtp for transfering local emails. the worst solutoin is that copy the email to all mailboxes via linux file system. But we would prefer to use some tools provided by dovecot like doveadm. is there any way to do this job?
