Trash Plugin bugs
by Alexei Gradinari 29 Apr '15

29 Apr '15

dovecot v2.2.16 I've found a few bugs in Trash plugin. 1. If Quota set only messages limit (without storage limit) then Trash plugin does not expunge any message because Quota plugin sets too_large_r=TRUE. It's because quota_default_test_alloc function does not check if bytes_limit is set. /* if size is bigger than any limit, then it is bigger than the lowest limit */ - if (size > bytes_limit) { + if (bytes_limit > 0 && size > bytes_limit) { *too_large_r = TRUE; break; } 2. Trash plugin does not use bytes_ceil/count_ceil to calculate size_needed/count_needed to expunge. Trash plugin may expunge more messages that nedeed. + if (ctx->bytes_ceil!=(uint64_t)-1 && ctx->bytes_ceil < size + ctx->bytes_over) { + size_needed = size + ctx->bytes_over - ctx->bytes_ceil; + } + if (ctx->count_ceil!=(uint64_t)-1 && ctx->count_ceil < 1 + ctx->count_over) { + count_needed = 1 + ctx->count_over - ctx->count_ceil; + } + /* not enough space. try deleting some from mailbox. */ - ret = trash_try_clean_mails(ctx, size + ctx->bytes_over, - 1 + ctx->count_over); + ret = trash_try_clean_mails(ctx, size_needed, count_needed); 3. Trash plugin does not check 'unlimited' values in bytes_ceil/count_ceil and may overflow them when add expunged size/messages - ctx->bytes_ceil += size_expunged; - ctx->count_ceil += expunged_count; + if (ctx->bytes_ceil!=(uint64_t)-1) { + ctx->bytes_ceil += size_expunged; + } + if (ctx->count_ceil!=(uint64_t)-1) { + ctx->count_ceil += expunged_count; + } See attached patch.

seeking sasl configuration example

hi everyone could someone show me there sasl configuration section in their dovecot.conf, i have postfix and dovecot setup for virtual users (no system users) everything works fine including tls, i have tried various examples off the web for sasl but they either have obsolete parameters or are for a setup with system users, i would prefer to use dovecots sasl implementation. dovecot --version = 2.1.7 cat dovecot.conf ###################### ###################### disable_plaintext_auth = no mail_privileged_group = mail log_path = /var/log/dovecot.log # auth_verbose=yes # auth_debug=yes # auth_debug_passwords=yes mail_debug=yes # verbose_ssl=yes passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = "pop3 imap lmtp" protocol imap { mail_plugins = " autocreate" } plugin { autocreate = Trash autocreate2 = Sent autocreate3 = junk autosubscribe = Trash autosubscribe2 = Sent autosubscribe3 = junk } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } protocol lmtp { postmaster_address=postmaster(a)mydomain.com hostname=niya.mydomain.com } ssl_cert = </etc/ssl/certs/mailcert.pem ssl_key = </etc/ssl/private/mail.key ###################### ###################### thanks shadrock

Quotas not working after reboot

Hello, after rebooting my dovecot server quotas are no longer working. # dovecot --version 2.2.10 CentOS Linux release 7.0.1406 It is strange that restarting dovecot did not reveal this problem, but rebooting whole server did.

[patch] TLS Handshake failures can crash imap-login
by Hanno Böck 27 Apr '15

27 Apr '15

Hi, I tracked down a tricky bug in dovecot that can cause the imap-login and pop3-login processes to crash on handshake failures. This can be tested by disabling SSLv3 in the dovecot config (ssl_protocols = !SSLv2 !SSLv3) and trying to connect with openssl and forced sslv3 (openssl s_client -ssl3 -connect localhost:995). This would cause a crash. What was going on is this: In ssl-proxy-openssl.c in line 545 in the function ssl_step() the function ssl_handshake() is called. There SSL_accept() is called. If SSL_accept failes - because a client sent an invalid packet or something the server doesn't support or any other reason - ssl_handle_error() will be called. ssl_handle_error() will call ssl_proxy_destroy(). ssl_proxy_destroy() will then call ssl_proxy_flush(). And ssl_proxy_flush will call ssl_step() again. Here we have a loop. Now when SSL_accept() gets called again on the same context this is an invalid state for OpenSSL and it crashes. What to do? In essence, if ssl_proxy_destroy is called it shouldn't try to finish the handshake if the handshake hasn't even started due to an error. This can be done by a simple if check, see attached patch. I think this should do it. I have seen that a bug that is probably rootet in this has been posted here before regarding ssl3-disabled configs: http://dovecot.org/pipermail/dovecot/2015-March/100188.html cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

Using Identities to send Emails, question on Email Storage
by Kevin Laurie 27 Apr '15

27 Apr '15

hi, i was wondering that when sending mail with a different identity(bob(a)mydomain.com using help(a)mydomain.com identity), why does it not copy the message to help(a)mydomain.com(Sent box). instead it only shows it on bob(a)mydomain.com(Sent box). appreciate if someone could advise. could someone advise how to fix this as i would like to see the message in help(a)mydomain.com(SentBox) too. thanks kevin

prefetch not working (for me) on ldap user backend
by Hector M. Jacas 26 Apr '15

26 Apr '15

Dear Sir, I'm having problems with the implementation of prefetch userdb. Following the directives from the site (http://wiki2.dovecot.org/UserDatabase/Prefetch) I am unable to avoid the second search to the user backend (ldap). Could give me any advice or tips to achieve my goal? Thanks a lot, Hector M.

Auth-worker, Unknown User
by Stephen R Guglielmo 25 Apr '15

25 Apr '15

Hi list, I'm running Debian Jessie (8). I have Postfix and Dovecot working successfully. I attempted to setup LMTP in order to enable sieve support, but it seems I was not successful. Dovecot version 2.2.13. Postfix accepts an incoming test mail I sent, then tries to deliver it to Dovecot via LMTP: dovecot: lmtp(13493): Connect from local dovecot: auth-worker(13495): pam(srg(a)example.com): unknown user dovecot: lmtp(13493): Disconnect from local: Successful quit Postfix then bounces my mail with a "550 User doesn't exist." It seems that Dovecot is trying to lookup my whole address (srg(a)example.com) in PAM instead of just the username ("srg"), which does exist. What can I do to avoid this? I have searched the internet about this and found a few references to "args = %s" and "args = username_format=%n" for passdb and/or userdb, but I have tried both (restarting Dovecot) to no avail. Thank you! `doveconf -n` below: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab103.6 x86_64 Debian 8.0 auth_verbose = yes first_valid_uid = 1000 last_valid_uid = 1000 listen = 167.114.96.243, 2607:5300:100:200::fce lmtp_save_to_detail_mailbox = yes mail_location = maildir:~/Maildir 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 } plugin { recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 0 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl_cert = </etc/ssl/private/dovecot.cacert.pem ssl_cipher_list = HIGH:!aNULL:!eNULL:!EXP:!SSLv2 ssl_dh_parameters_length = 2048 ssl_key = </etc/ssl/private/dovecot.privkey.pem ssl_prefer_server_ciphers = yes ssl_protocols = TLSv1 TLSv1.1 TLSv1.2 userdb { driver = passwd } protocol lmtp { mail_plugins = sieve }

Performance

Hi, at moment I have this environment: CentOS nginx + phpfpm Dovecot, with Maildir format Postfix Roundcube MySQL backend about 10000 mailusers dual core Intel(R) Pentium(R) D CPU 3.00GHz 8 GB RAM network storage device (Coraid), ext4 file system I have no performance issue now, but I need to move to a different server: FreeBSD 10.1-RELEASE nginx + phpfpm Dovecot Postfix Roundcube dual core Intel(R) Xeon(R) CPU 5120 @ 1.86GHz 16 GB RAM local storage with zfs file system My question is: is better to use SQLite instead of MySQL? Should I prefer dbox format? Thank you in advance for your opinion!

[BUG] imap-login segfault when running nmap -sV
by Florian Pritz 24 Apr '15

24 Apr '15

Hi, I've noticed that nmap crashes my imap-login (also pop3-login) and narrowed it down to `nmap -sV -p 993 $host`. I've noticed that if I remove "ssl_protocols = !SSLv2 !SSLv3" from my config or enable SSLv3 rather than disabling it the segfault disappears. I'm running on Arch Linux with dovecot 2.2.16-1 and openssl 1.0.2.a-1. I've also attached a network capture, but since it's SSL this probably won't help all that much. I hope this is enough information to reproduce the issue. If necessary I can recompile dovecot with debug symbols for a better backtrace.

acl and lazy_expunge plugins are incompatible?
by Paolo Cravero 24 Apr '15

24 Apr '15

Hello list. Following two previous unanswered requests (http://www.dovecot.org/list/dovecot/2014-August/097449.html and http://www.dovecot.org/list/dovecot/2014-May/096261.html) I fell into the same problem: ACL and lazy_expunge plugins do not work together. I had lazy_expunge enabled working OK. Then I activated ACL plugin, and gave dovecot.2 visibily over paolo.cravero's Inbox: the IMAP connection fails on server-side. Relevant debug log is: Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: Quota grace: root=User quota bytes=576716800 (10%) Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: dict quota: user=paolo.cravero(a)csi.it, uri=file:/maildata1/home/csi.it/p/paolo.cravero/dovecot-quota, noenforcing=0 Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: fs: root=/maildata1/main/csi.it/p/paolo.cravero, index=/maildata1/indexes/csi.it/p/paolo.cravero, indexpvt=, control=, inbox=, alt=/maildata1/altstorage/csi.it/p/paolo.cravero Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl: initializing backend with data: vfile Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl: acl username = paolo.cravero(a)csi.it Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl: owner = 1 Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl vfile: Global ACLs disabled Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' Removing the lazy_expunge, ACLs do work as expected and I can add/remove/use them.

Moving a local domain to sql
by ＠lbutlr 22 Apr '15

22 Apr '15

I have a domain that current maps to local users that I want to move into the mysql maps with all the other domains, but I am unsure of the best way to proceed with this. For example, my mail server is covisp.net and my personal domain is kreme.com, and currently kremels(a)kreme.com maps to the local user kremels. I want it to map to the existing mysql database as “kernels(a)kreme.xn--com-9o0a. (For example only, I’m not moving kreme.com, I am too dependent on procmail for all my list processing). Once I setup the user account in the mysql database do I just move the Maildir from /home/kremels to /usr/local/virtual/kremels(a)kreme.com/ and reload dovecot? -- I leave symbols to the symbol-minded - George Carlin

dovecot efficient use of resources
by shouddy＠enet.cu 22 Apr '15

22 Apr '15

I just started a heavy load imap service and everything fitted OK in functional terms. The problem comes whith stress tests, I have no problem in the directors line. But my doubt comes whether the backends are using efficiently the resources assigned or not. The main goal is to maximize the concurrency without affect the integrity of operations. My question is: Is there a rule for relating the amount of computing resources (RAM, Processor) with the number of simultaneous connections to an IMAP/POP3 server running dovecot? I had made all the adjustmens for high performance in dovecot according to the docs and O.S specs Backend's hardware Processor: AMD Opteron(tm) Processor 6136 RAM: 16 GB HDD: Enought for testing I'm confident the NFS layer is not making noise (yet). Comparing the results, the output of tests are giving consistent numbers using local file systems (all of them properly tuned) I have run the tests with imaptest but even with 100 clients I'm having system's max load of 46 stable. I have the sense that memory is not using properly (2GB at most from 16GB). Thank you so much in advance, would be grateful for any help Conf below Dovecot version 2.2.10 doveconf -n # OS: Linux 3.10.0-123.20.1.el7.x86_64 x86_64 Red Hat Enterprise Linux Server release 7.0 (Maipo) nfs4 auth_mechanisms = plain login default_client_limit = 4000 disable_plaintext_auth = no listen = * mail_fsync = always mail_gid = 500 mail_location = maildir:/var/vmail/mailboxes/%d/%8n/%n:INDEX=MEMORY mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 500 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 { 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-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { client_limit = 14400 service_count = 0 unix_listener auth-userdb { group = vmail mode = 0640 user = vmail } } service doveadm { inet_listener { port = 24245 } } service imap-login { client_limit = 1000 process_limit = 100 process_min_avail = 16 service_count = 0 vsz_limit = 512 M } service imap { process_limit = 7000 service_count = 0 } service pop3-login { client_limit = 1000 process_limit = 100 process_min_avail = 16 service_count = 0 } service pop3 { process_limit = 7000 service_count = 0 } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_max_userip_connections = 1000 } local 172.28.200.0/24/24 { doveadm_password = secret }

Please help: error after upgrade to version 2.1.16
by Harald Langner 18 Apr '15

18 Apr '15

Hallo I can not find a forum at dovecot.org and I get a problem I can not solve. After Updating to the version dovecot2 2.1.16 I can no more get eMails with my eMail-client. All has been working fine before. Server: FreeBSD 10.0-RELEASE-p18, with perl 5, version 18, subversion 4 (v5.18.4) It seems it is an authentication problem with my server. The errors are: #cat dovecot.log Apr 17 22:19:37 imap-login: Error: Timeout waiting for handshake from auth server. my pid=41810, input bytes=0 Apr 17 22:19:58 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Apr 17 22:19:58 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Apr 17 22:19:58 master: Error: service(auth): command startup failed, throttling for 60 secs Apr 17 22:24:04 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Apr 17 22:24:04 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Apr 17 22:24:04 master: Error: service(auth): command startup failed, throttling for 60 secs I have google and has nothing found about "..environment corrupt; missing value for DOVECOT_" and about "auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address" I have make a reinstall - but doesn't help. I get the same error. I have not forget to create new certs with the dovecote shell-script after installation. I'm using passwd (virtual users). Make a cat on passwd shows that it is not empty. Also the date of the file show that the update installation has it not changed. So I have not create the dovecot users again. here are some other logs: #cat dovecot-info.log Apr 17 22:29:03 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 1 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS handshaking Apr 17 22:29:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 30 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS Apr 17 22:29:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 30 secs): user=<>, rip=85.181.222.126, lip=78.47.225.20, TLS #cat dovecot-debug.log Apr 17 22:30:03 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Apr 17 22:30:03 auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat Apr 17 22:34:01 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Apr 17 22:34:01 auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat Apr 17 22:34:01 imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client certificate A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] Apr 17 22:34:01 imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [85.181.222.126] ######################################################################################## My configuration is sendmail(MTA) -> procmail(LDA) -> dovecot(IMAP) with TLS and Maildir (no DB) Authentification been done with dovecot password file (no real user, no OpenLDAP, no other DB-User) #dovecot -n # 2.2.16: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.0-RELEASE-p18 amd64 ufs auth_debug = yes auth_mechanisms = digest-md5 plain login auth_verbose = yes auth_verbose_passwords = plain base_dir = /var/run/dovecot/ debug_log_path = /var/log/dovecot-debug.log default_internal_user = vmail default_login_user = vmail deliver_log_format = msgid=%m: %$ %f %s disable_plaintext_auth = no first_valid_uid = 1000 hostname = swdevil.de info_log_path = /var/log/dovecot-info.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /var/log/dovecot.log login_greeting = IMAPd ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_access_groups = mailnull mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/:INBOX=/home/vmail/%d/%n/.INBOX mail_plugins = " virtual" mail_temp_dir = /tmp/mail namespace inbox { inbox = yes location = prefix = } passdb { args = scheme=DIGEST-MD5 username_format=%n /usr/local/etc/dovecot/pass driver = passwd-file } service auth-worker { group = wheel user = root } service imap-login { group = dovenull inet_listener imap { port = 0 } inet_listener imaps { port = 993 } } service imap { process_limit = 100 } service pop3-login { group = dovenull inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 } } service pop3 { process_limit = 100 } ssl = required ssl_cert = </usr/local/etc/dovecot/certs/dovecot_ssl_crt.pem ssl_key = </usr/local/etc/dovecot/certs/dovecot_ssl_key.pem userdb { args = uid=vmail gid=vmail home=/home/vmail/%d/%n driver = static } verbose_proctitle = yes verbose_ssl = yes protocol pop3 { pop3_uidl_format = %08Xu%08Xv } Many thanks for Your advice what could be wrong.

Problem: mail moved by thunderbird script is invisible to mail clients, but in cur directory
by David Gessel 18 Apr '15

18 Apr '15

Over the last year I've had a script moving old mail (120 days) into my annual archive folder. This is the first year I've done this with Dovecot, previously it was running against Cyrus. There's nothing particularly clever: a few conditions to match, then "move message to" the appropriate archive folder. There's one for every year from 2000 to 2015. 2015 is just barely ahead of need. 2014 has about a year's mail in the cur directory. The 2000-2013 folders were filled by Cyrus and were migrated over using IMAP Migrate. They're fine, and read normally. The 2014 layout looks normal to me # ls cur dovecot-uidlist dovecot.index.cache dovecot.index.log.2 new dovecot-keywords dovecot.index dovecot.index.log maildirfolder tmp Permissions are the same as every other folder, as is owner: drw-r----- 2 vmail vmail 9.6K Apr 12 21:13 cur and # ls | wc -l 9822 I've checked with Thunderbird, Mulberry, Claws, and Sylpheed - none can read the directory. The files look normal: 2014/cur 1426411329.M123928P26360.host.domain.com,S=3523,W=3591:2,R More or less the same as a working directory: 2013/cur 1405500734.M958596P27867.host.domain.com,S=794,W=819:2,RS I've run # doveadm force-resync -u user .archives.2014 and nothing changed. I'm at a bit of a loss since no client can read them, something like moving them to another folder and back is a little complicated. Any hints?

Replace autocreate after upgrading
by trash＠skrilnetz.net 17 Apr '15

17 Apr '15

Hi, I just upgraded to 2.2.9 and found out that autocreate should not be used any more. I had a look at http://wiki2.dovecot.org/MailboxSettings and I tried to replace my old config but I had no success. Would somebody be so and help me to change my config? Here is my old config: http://pastebin.com/zFUAQmV3 Thanks,

Potentially breaking dict-proxy (dict-sql) backwards compatibility
by Timo Sirainen 17 Apr '15

17 Apr '15

Looks like the dict-proxy code doesn't currently do escaping newlines properly, but it still accidentally happens to work, because the data is stored in the escaped form. I'm thinking about fixing this, but this might break somebody's existing dict usage. But then again maybe nobody is actually using it now, especially because it hasn't been working exactly as expected. So, can anybody tell me if they're currently using a combination of: - dict proxy (especially to dict sql) - containing values which can contain LFs (or TABs) I guess this mainly means storing Sieve scripts or IMAP METADATA to SQL. Or maybe somebody is using dict (via proxy) for their own purposes?..

Thunderbird sync time? (reverse quota warning)
by E.B. 16 Apr '15

16 Apr '15

For reverse quota warning, it looks like webmail works nice. quota_warning3 = -storage=100%% quota-warning below %u # user is no longer over quota But using thunderbird I deleted enough messages to go below quota and I deleted them from trash folder too. But mail log does not show thunderbird connecting to imap to actually delete mails and get the trigger below quota warning msg. It's i thinks a thundrbrd behavior but i wonder if anyone on this list knows how it works? Do i just keep waiting for it to sync eventually? or??????? TIA!

Dovecot and recipient_delimiter

Disk space usage with mdbox
by Alexandros Soumplis 15 Apr '15

15 Apr '15

Hello, I am using dovecot with mdbox+sis and I notice an ever increasing disk space usage since I converted mailboxes from Maildir to mdboxes. I have checked with a user and while it actually uses only 65K, his mdbox files on disk are more than 6G. The backup of his mailbox is just 64K. Any suggestions ? Below are some relevant commands: [root@mail ~]# doveadm quota get -u test Quota name Type Value Limit % User quota STORAGE 10135 31457280 0 User quota MESSAGE 186 - 0 [root@mail ~]# du -k --max-depth=1 /mdboxes/test/ 220 /mdboxes/test/mailboxes 6029348 /mdboxes/test/storage 6029592 /mdboxes/test/ [root@mail ~]# doveadm purge -u test [root@mail ~]# du -k --max-depth=1 /mdboxes/test/ 220 /mdboxes/test/mailboxes 6029348 /mdboxes/test/storage 6029592 /mdboxes/test/ [root@mail ~]# doveadm backup -u test mdbox:/tmp/MDBOX_TEMP/ [root@mail ~]# du -k --max-depth=1 /tmp/MDBOX_TEMP/ 16 /tmp/MDBOX_TEMP/mailboxes 65540 /tmp/MDBOX_TEMP/storage 65568 /tmp/MDBOX_TEMP/

setting service_count results in Permission denied
by Micah Anderson 15 Apr '15

15 Apr '15

The load on our machines has gotten too high, so I started to see log messages that directed me to look at this page for config changes: https://pad.riseup.net/redirect#http%3A//wiki2.dovecot.org/SocketUnavailable One of the things I wanted to do on that page was to set the: service imap { service_count = 100 } but when I added that to the service imap block, and restarted dovecot, I see this in the logs: Error: net_connect_unix(/run/dovecot/imap-postlogin) failed: Permission denied I dont understand how this impacts permissions. Its clearly this setting, because when I remove it, things work again. I found nothing else in the logs indicating a configuration problem. This is what the config block looked like: service imap { # Most of the memory goes to mmap()ing files. You may need to increase this # limit if you have huge mailboxes. #vsz_limit = 256M # Max. number of IMAP processes (connections) process_limit = 4096 service_count = 100 executable = imap imap-postlogin } service imap-postlogin { # the script process runs as the user specified here (v2.0.14+): #user = $default_internal_user executable = script-login /usr/local/sbin/postlogin_imap # this UNIX socket listener must use the same name as given to imap executable unix_listener imap-postlogin { } } This is with dovecot 2.2.13, thanks for any help you can provide! micah

concurrent IMAP connections (plus 2 easy questions)
by Ron Cleven 15 Apr '15

15 Apr '15

I posted a few days back asking about configuration issues with a modestly large number of IMAP connections. Several people were kind enough to respond with various ideas. Armed with those ideas and Google, I was able to determine the underlying configuration issues with CentOS 7 and Dovecot 2.2.10. I did some further benchmarking to ensure that we could properly plan our server configuration requirements as we continue to roll this out, so I thought I would share this, partly to see if anyone has experiences that conflict with my findings. I found that each incremental dovecot IMAP process required about 750k of RAM. Simulations confirmed that 8 gig of RAM was sufficient to support approximately 10,000 concurrent IMAP connections (no POP3). CentOS settings: Added: fs/inotify/max_user_instances = 28000 to: /etc/sysctl.d/99-sysctl.conf Added: * hard nproc 28000 * soft nproc 28000 * hard nofile 28000 * soft nofile 28000 to: /etc/security/limits.d/20-nproc.conf To verify the settings after reboot: cat /proc/sys/fs/inotify/max_user_instances ulimit -Hn ulimit -Sn Dovecot: Added: process_limit = 28000 to service imap{} /etc/dovecot/conf.d/10-master.conf Added (using proxies, would like to just turn off this check): mail_max_userip_connections = 40 to protocol imap {}: /etc/dovecot/conf.d/20-imap.conf Added: process_limit = 28000 to service managesieve {}: /etc/dovecot/conf.d/20-managesieve.conf Hope this helps someone. Feedback would be welcome. It would be great if there was a blessed cookbook for Dovecot scaling. At this point it seems a bit like an art form. Now to my two "easy" questions. 1) TCP replication between our two CentOS boxes has been working great, no complaints. However, I realized I did not know how to check the status of replications, as one might want to do if one of the two boxes was taken offline for maintenance or repair. On the surface, it would appear that the command: doveadm replicator status '*' would likely show me what I want to know. However, when I tried it, I got: doveadm(): Fatal: net_connect_unix(/var/run/dovecot/replicator-doveadm) failed: No such file or directory The documentation says that doveadm assumes the socket /var/run/dovecot/replicator-doveadm and the command format provides a "-a" override. In that directory, there is no "replicator-doveadm" socket, but I do see a "replicator" socket. So, should I be using the command: doveadm replicator status -a /var/run/dovecot/replicator '*' or is the non-existence of the replicator-doveadm socket indicative of something I might have done wrong with the config? I hate experimenting more than I have to with a production box. The 2.2.10 Dovecot I am running was installed via yum, so there are no potential compilation issues. 2) It seems logical to me that: dovecot stop would first lock out any new user connections, then do the equivalent of a: doveadm kick "*" before actually cycling everything else down to ensure the shutdown is as graceful as possible. I suppose I could experiment and find out for certain, but I have the sense that the "stop" command is not quite that elegant, so we have implemented procedures to work around it. Just a point of curiosity. An alternative would be if there was a doveadm command to lock out any new user connections, which could then be followed by kick and stop. I have found that many clients are VERY quick to reconnect after a kick.

special_use folders
by Roman Gelfand 13 Apr '15

13 Apr '15

My setup is postfix mail gateway/spamassassin on one machine and dovecot mail box server on another machine. Will the following configuration work? 1. On the mail gateway, I install dovecot-lmtp and use it to deliver locally spam. 2. On the mailbox server, I configure special use junk folder to point mail gateway's spam folder via nfs. If this is correct, how can I configure special use folder to point to a path (variable based on email) which is different from default path? If there is a different way to handle this, I would interested. Thanks in advance

dovecot debug message help required
by Rajesh M 13 Apr '15

13 Apr '15

hi i was carrying out some testing using qmailtoaster with dovecot on a centos 64 server i am connecting to the mailbox using a windows machine with outlook across the lan. the mailbox is around 7gb in size with around 12000 emails spread across multiple folders and i am trying to sync the mailbox folders to by creating an account imap account in outlook. the mails are getting downloaded in the imap folder but the sync does not complete and outlook throws an error. Task 'Synchronizing subscribed folders for user(a)mydomain.com.' reported error (0x800CCC0F) : 'Outlook cannot synchronize subscribed folders for user(a)mydomain.com..

Disabling of userdb/passdb modules using config statements
by Jeroen Massar 13 Apr '15

13 Apr '15

Hola, Debian (and possibly other distros) use the /etc/dovecot/conf.d/* setup where default config files are stuffed and then one can just add a 99-myconfig.conf et voila, variables are overruled. This allows the distro to supply updates to the files at package upgrade time without any/much user intervention. The problem (for me ;) is that the system comes provided with: auth-system.conf.ext containing: passdb { driver = pam } userdb { driver = passwd } Hence pam & /etc/passwd based are always enabled. This while I don't have any local users. Replication seems to then always pick up the local users, which are vmail + nobody (65536). doveadm user '*' thus reports vmail, nobody + virtual users Setting: first_valid_uid = 5000 last_valid_uid = 5000 only keeps vmail in there, but apparently some module (guess replication) is still able to figure out that 'nobody' exists: Apr 10 09:48:25 mail dovecot: doveadm(IPADDR,nobody): Error: Mail access for users with UID 65534 not permitted (see first_valid_uid in config file, uid from userdb lookup). Apr 10 09:48:25 mail dovecot: doveadm(IPADDR,nobody): Error: dsync-server: User init failed Apr 10 09:49:38 mail dovecot: doveadm(nobody): Error: sync: Failed to start remote dsync-server command: Remote exit_code=75 and on the other side: Apr 10 09:54:38 mail dovecot: doveadm(nobody): Error: sync: Unknown user in remote This can be resolved by commenting out the entries in auth-system.conf.ext but then I'll have to do that again at package upgrade time. Hence, would it be a cool option to be able (in the 99-myconfig.conf) file to put: passdb { driver = pam enabled = false } userdb { driver = passwd enabled = false } And thereby disabling those modules completely? Thus avoiding upgrade conflicts etc. Greets, Jeroen

Calendar and address book with Dovecot
by mimicafe＠gmail.com 10 Apr '15

10 Apr '15

Hi all I recently install Postfix and Dovecot, and so far so good. My assumption was that calendar and address book (similar to Gmail calendar or address book) are part of Dovecot. However I do not see anything concerning them in any of the docs I have read so far. What other software (ideally open source, free) do I need in other to have Calendar and address book so my users can manage their contact on their phones or computer? I have looked at Roundcube already, but my requirement is not necessarily to provide web mail. Thanks Mimi

pop3 retr responses too large lines - Fails with current python's poplib
by Guillermo M. Narvaja 10 Apr '15

10 Apr '15

Since December 2014, clients using the Python poplib library (getmail in my case) started to limit the line length of RETR and other command responses sent from the server to 2048 bytes: See https://bugs.python.org/issue16041 (Included at least in Python-2.7.9) Dovecot doesn't have line split in the POP3 module, so Python fails to retrieve messages with long lines. RFC 1939 says: " Responses in the POP3 consist of a status indicator and a keyword possibly followed by additional information. All responses are terminated by a CRLF pair. Responses may be up to 512 characters long, including the terminating CRLF. " I think dovecot-pop3 should split it's output in lines of at least 512 characters. Or at least it should have a "pop3_max_line_length" setting (like "imap_max_line_length").

Hola, Dovecot: 2.2.16 (6bde7868cffd) That is the rename-it 2:2.2.16-1~auto+43 edition.

I would not be surprised if this was related to a broken index, as the other side effect I saw during this sync was an ever-expanding maildir (read: sdbox), multiplying itself during sync, keeping large amounts of the the .temp.<xxxx> in the dir, never moving them to a final directory. That was resolved by stopping dovecot, then deleting the broken sdbox (backups++) and performing a 'dovecot force-resync -u user Folder' on the source. Maybe there was a race somewhere while syncing the large amount of data over; seems that everything is okay now though. Greets, Jeroen

sa-learn with remote Dovecot folders
by Andreas Kasenides 10 Apr '15

10 Apr '15

Hi all! The set-up I have is a classic one: 1. one or more Dovecot relay/directors Postfix SMTP servers in DMZ 2. one or more backend IMAP/SMTP servers on the inside network 3. There may or may not be separate incoming or outgoing designated SMTP servers. Now the desired functionality is (of course): 1. relay machines receive messages from outside AND inside 2. relays check for all the bad things (spam, viruses etc). 3. for incoming messages relays check for valid local users and reject messages for invalid users 4. after all checks are done incoming messages are transferred to the backend systems where they are accessed via the Dovecot directors While all the above works nicely, the problem I have is how to train my spamassassin (used by amavisd) on the front ends when all messages are on the back ends. Of course transferring the spam detection procedures internally is not such a great option.Am I missing something? I tried googling for info but nothing substantial turned up. Thanks. -- Andreas Kasenides Senior IT Officer Dept. of Computer Science, University of Cyprus Tel: 22892714, Fax: 22892701 (5B4ANK)

gmail-migration: archived mails in \ALL
by Peer Heinlein 10 Apr '15

10 Apr '15

Hi, I don't completly understand http://wiki2.dovecot.org/Migration/Gmail I can't find the documentation for the -a and the -F Flag. I'd like to migrate ONLY archived mails from an existing gmail-Account. So I'd have to import all Mails from the \ALL-Folder that does NOT have any virtual folder flags set. I tried to use this command: doveadm -D -o imapc_user=user(a)example.com -o pop3c_user=user(a)exampe.com -o imapc_password=secret -o pop3c_password=secret -o imapc_host=imap.googlemail.com -v backup -m '[Gmail]/Tutti i messaggi' -F '-$GmailHaveLabels' -x \Flagged -x \Junk -x \Trash -x \Important -R -u user(a)example.com imapc: But it looks like it's importing too many mails and not only the archived mails without Flags. How do I have do understand -F '-$GmailHaveLabels ?? Is it "that NOT have $GmailHaveLabels"? And: Is there any better way to address the \ALL-Folder? I can use "-x \All" to exclude that folder, but it looks like I can't use "-m \All" to select that folder. We're a little bit in hurry since Google will stop its service this weekend. Any fast help would be appreciated.

Sieve, multiple addresses, and variables
by Andrew Sullivan 08 Apr '15

08 Apr '15

Hi, I have another sieve question, this time about setting variables. I join a lot of mailing lists at ietf.org. I thought it'd be handy to filter these all into a common folder and then into individual folders, without having to configure each mailing list independently. So wrote this (this is just a part, obviously): require ["envelope", "variables", "date", "fileinto", "mailbox" ]; if address :is :domain "to" "ietf.org" { if address :matches :localpart "to" "*" {set "lopart" "${1}";} } elsif address :is :domain "cc" "ietf.org" { if address :matches :localpart "cc" "*" {set "lopart" "${1}";} } else {set "lopart" "generic-list-box";} fileinto :create "ietf.${lopart}-in"; stop; } Now, this works, unless someone sends a To: line like this: To: ajs(a)crankycanuck.ca, listname(a)ietf.org The problem in that case is that you _do_ get a match, but the bit "if address :matches :localpart "to" "*" {set "lopart" "${1}";}" ends up putting this in a mailbox ietf.ajs-in, when what is the mailbox ietf.listname-in. I thought that allof(if address :matches :localpart "to" "*", address :matches :localpart "to" "*") {set "lopart" "${1}";}, would solve this, but it doesn't seem to. The localpart matching catches the ajs(a)crankycanuck.ca address anyway, which surprised me. Am I dim, am I not understanding something about how to do this, or is this really impossible? Thanks, A -- Andrew Sullivan ajs(a)crankycanuck.ca

Hello Everyone, I'm running the antispam plugin on Dovecot 2.0.19 on Ubuntu Server 14.04 and I can't seem to get it to work. In the IMAP section of dovecot.conf I have the following lines: protocol imap { mail_plugins = $mail_plugins imap_quota imap_acl antispam # mail_plugins = $mail_plugins imap_quota imap_acl imap_client_workarounds = tb-extra-mailbox-sep # Maximum number of IMAP connections allowed for a user from each IP address. # NOTE: The username is compared case-sensitively. # Default is 10. # Increase it to avoid issue like below: # "Maximum number of concurrent IMAP connections exceeded" mail_max_userip_connections = 20 plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_trash = Trash antispam_spam = Junk antispam_pipe_program_spam_arg = --spam antispam_pipe_program_notspam_arg = --ham antispam_pipe_program = /usr/bin/sa-learn antispam_pipe_program_args = --username=%Lu } } For some reason, when I try to move something to Junk, I get the following in my syslog: Mar 31 18:27:16 anonymail imap: antispam: plugin initialising (2.0-notgit) Mar 31 18:27:16 anonymail imap: antispam: verbose debug enabled Mar 31 18:27:16 anonymail imap: antispam: "Junk" is exact match spam folder Mar 31 18:27:16 anonymail imap: antispam: no unsure folders Mar 31 18:27:16 anonymail imap: antispam: "Trash" is exact match trash folder Mar 31 18:27:16 anonymail imap: antispam: pipe backend spam argument = --spam Mar 31 18:27:16 anonymail imap: antispam: pipe backend not-spam argument = --ham Mar 31 18:27:16 anonymail imap: antispam: pipe backend program = /usr/bin/sa-learn Mar 31 18:27:16 anonymail imap: antispam: pipe backend program arg[0] = --username=anthony(a)cajuntechie.org Mar 31 18:27:16 anonymail imap: antispam: pipe backend tmpdir /tmp Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_unsure(Junk): 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_trash(INBOX): 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_trash(Junk): 0 Mar 31 18:27:19 anonymail imap: antispam: mail copy: from trash: 0, to trash: 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_spam(INBOX): 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_spam(Junk): 1 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_unsure(INBOX): 0 Mar 31 18:27:19 anonymail imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program /usr/bin/sa-learn Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program /usr/bin/sa-learn Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program parameter 1 --username=anthony(a)cajuntechie.org Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program parameter 2 --spam Mar 31 18:27:21 anonymail imap: antispam: run program failed with exit code -1 This is probably a permissions issue but I'm not able to debug it.

can't create folders under shared mailbox's INBOX

Hello, I have a namespace / ACL problem with shared mailboxes that I can't figure out. I have a local user tam(a)crm.yb.lmax that shares it's INBOX and all other folders with on LDAP group.

ACL syntax for setting specified folders within Maildir/ read-only for owner
by kepa 08 Apr '15

08 Apr '15

Hi, I have dovecot (2.2.16, see dovecot -n at end) installed to /opt on CentOS 6 for access on a local network. I would like to create an archival mail account which will reduce the primary account file size and still make older emails easily accessible. How can I set specified folders in this Maildir read-only with ACL? For example, I included this in the dovecot-acl file to specify protected folders in the archives@ Maildir but it did not work: "Email 2013/*" user=archives lrs "Email 2014/*" user=archives lrs Also tried this on folders without spaces with no success (the folders were still delete-able by the user via the Thunderbird client). Each "Email..." folder has several child folders that should also be read-only. BTW, what is the maximum size for a Maildir that Dovecot can comfortably handle? Thanks!

Dovecot keeps creating info files in mail directory instead of home
by Jeffrey 'jf' Lim 08 Apr '15

08 Apr '15

I've been trying to troubleshoot this for a while now, and I'm really at a loss. My userdb is set up correctly to return home, and mail, and a test with 'doveadm user' verifies this: # doveadm user user@domain field value uid 1000 gid 1000 home /var/domain/user mail maildir:/var/mail/user@domain I've reloaded, restarted, stopped and started dovecot again - and even deleted the info files in the mail directory just to be sure - but each and every time I log in with imap, dovecot recreates the files again (dovecot.index.log, dovecot-uidlist, etc.) in the mail directory instead of home. I've even made sure just in case that the home directory is accessible to all, and chmod 777, but nothing gets created there. And I dont get any errors at all in the logs.

Authentication with Samba using Kerberos fails
by Justin Clacherty 08 Apr '15

08 Apr '15

Hi, I've been having some problems getting GSSAPI authentication going against a samba (4.2) server and am hoping someone can point me in the right direction. I've searched through Google and haven't managed to find a solution yet. I followed the config instructions at http://wiki2.dovecot.org/Authentication/Kerberos and run through the testing. Testing from the server with telnet does as expected i.e. I get the "+" after I try "a authenticate GSSAPI". However, when I go to test from Thunderbird on while logged in on a Windows PC joined to the domain authentication fails and I see the following in mail.log (I'm running Ubuntu 14.04.2 LTS).

Deleting empty folders
by Samuel Williams 07 Apr '15

07 Apr '15

So, along with the problem of lots of folders ending in 1 1 1 1, I'd like to have a strategy to delete these. I was trying to understand if it is possible to use http://linux.die.net/man/1/doveadm-expunge to delete empty folders, but without also deleting messages? Is this possible and if so what is the syntax? Kind regards, Samuel

What to read about interactions
by Andrew Sullivan 07 Apr '15

07 Apr '15

Hi, TL;DR: I am having a hard time synthesizing the information I need out of the website/wiki documentation, and google isn't turning up what I need, so I'm looking for advice on what I should read next to understand the way aliases, dovecot's lmtp, and pigeonhole work together. Details below. I've been using dovecot happily for some years, but in a recent migration of my mail server I set up something that I think will be slightly easier to maintain. I now have a single (in my case postgres) database backing all user names and so on, with postfix relying on dovecot auth for user validation and delivery. I have the usual anti-spam machinery in there, and have started using the (for me new) pigeonhole implementation of sieve. (My old mail system was built around the earlier dovecot implementation, and while I've patched it over time it's really pretty creaky.) On the whole, this all seems very nice, but I'm having a hard time understanding the details of what interacts with what other bits when. In particular, my mail system is known by several different names, and I thought it'd be much handier to have everything land in one real mailbox, since I could sort the inbound mail into different mailboxes without a lot of trouble using seive. This has turned out to be slightly trickier than I thought it ought to be (procmail is in some ways easier), and I've come to the conclusion that I don't have a strong foundation in exactly how this is supposed to work. Apart from reading the code (which would probably at this point be hard enough for me so as to make it impossible), are there things I ought to read to understand this better? I've read the seive RFCs, but while that gives me a clue about what ought to happen protocol-wise, it isn't helping me at all to understand the interaction among the different subsystems so that I can see clearly how different parts of the delivery chain are interacting. I'm sure there's some crucial bit of, "Everyone knows that," that I've overlooked, and I thought it would be better to ask for the FM than just to read randomly until I stumbled on it.

If you see, some folders got strange names. 41943652 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:42 INBOX 1 42205306 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:46 INBOX 1 1 42336882 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:48 INBOX 1 1 1 42337295 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:49 INBOX 1 1 1 1 42598861 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:51 INBOX 1 1 1 1 1 42730114 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:54 INBOX 1 1 1 1 1 1 42730261 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:57 INBOX 1 1 1 1 1 1 1 42730276 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:57 INBOX 1 1 1 1 1 1 1 1 42730291 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:58 INBOX 1 1 1 1 1 1 1 1 1 42730306 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:59 INBOX 1 1 1 1 1 1 1 1 1 1 42730321 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:00 INBOX 1 1 1 1 1 1 1 1 1 1 1 42730336 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:01 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 42730351 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:02 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 42730366 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:03 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 1 42730381 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:04 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 42730400 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:05 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 and so on.....

Using dovecot to serve an email archive
by Ramón Casares 06 Apr '15

06 Apr '15

I have a collection of old email messages, archived as follows: 1) One file per message. 2) Messages (=files) distributed in a hierarchy of dirs under mailarch. 3) Each file (=message) uses the name <seconds>.R<sha1>.mail Here <seconds> is the date of the message, expressed as the number of seconds from 1-1-1970 00:00 in 10 digits, and <sha1> is the SHA-1 hash of the message contents, expressed in hexadecimal, [0-9a-f]. The advantages of this file naming scheme are: 1) All important metadata are in the file name. 2) You can verify the integrity of each message using only its own data and metadata. 3) Each file name is unique. 4) It is compatible with maildir (qmail) unique names (uniq). 5) If a dir is sorted alphabetically, then it is ordered chronologically. 6) The extension .mail can be used to call an appropriate message reader. >From time to time I add new messages and dirs to the archive, but some dirs are closed forever, so it would be nice to tar.gz'ip them. Now I am looking for an IMAP server that can serve this collection in a read-only (ro) manner. That is, the server should not write the mailarch dir at all. I am exploring two possibilities: 1) using hard links. 2) using FUSE to set a rw layer on top of the ro archive layer. But I am new to dovecot, so perhaps there is an easier way to achieve what I want, and therefore I would appreciate very much your advice.

Sieve/ManageSieve documentation on Wiki2
by Robert Blayzor 06 Apr '15

06 Apr '15

Is it possible the Sieve/ManageSieve documentation on the Wiki can be cleaned up? It's incredibly confusing now. Some of the Sieve configuration information says certain options are deprecated, but then the example on how to configure it uses the deprecated options rather than what they *should* be now. More confusion is the sieve plugin configuration listing those same deprecated options, yet when you pull the document on how to configure ManageSieve, it (again) uses deprecated configuration information? http://wiki2.dovecot.org/Pigeonhole/ManageSieve/Configuration Or am I missing something? -- Robert inoc.net!rblayzor http://inoc.net/

IMAP logging / rawlog
by G H 06 Apr '15

06 Apr '15

I am trying to monitor with Nagios that my phones are consistently checking into dovecot via IMAP. I used to be able to parse syslog for imap-login messages. I have since updated my phones, the phoness email client (k9-mail) and dovecot. Now the imap-login messages are few and far between. However, I can clearly see via tcpdump that some traffic is happening when I click refresh on k9. I enabled "rawlog" support in dovecot, but it doesn't seem to write to disc frequently enough. 1) Does anyone have a better suggestion for how to monitor that my phone is checking in regularly? 2) Is there a flush-to-disk capability for rawlog in dovecot? 3) Also, when you have imap_zlib plugin enabled, the rawlog logs the raw compressed data instead of the decompressed IMAP commands. Is this an oversight? (FYI: k9 is calling SELECT "INBOX" on refresh) Thanks, G H

Question About Dovadm syntax
by Kenneth Ulrich 06 Apr '15

06 Apr '15

Hello All, I just have a quick question about doveadm commands. 1. Is there a command that we can use to count emails for a particular end user? 2. If an end user needed to copy/move emails from one account to another, is there a command? Also, I've searched Google results, numerous Ubuntu, CentOS, Fedora forums, Doveadm forums, and read the DoveCot/DoveADM man pages numerous times and either I am over looking, or I am not understanding. Thus why I am asking here.

speaking of sieve scripts... how to selectively not send vacation autoreply
by Harondel J. Sibble 04 Apr '15

04 Apr '15

Don't need to block anyone like in the "Re: Dovecot Oy merger with Open-Xchange AG" thread, but when I have my vacation recipie active, I'd like it to NOT reply to certain addresses. I tried the following, you can see the section with if header :contains "addressIdontwant(a)repliedtoo.tld" is commented out, once I'd added that section, no Vacation messages went out at all. Googling and reading the wiki and recipie suggestions doesn't make it clear how to exempt a list of addresses from ever receiving a vacation response. Suggestions on additional reading or solutions? require ["fileinto", "vacation"]; if header :comparator "i;ascii-casemap" :contains "Subject" "**SPAM**" { fileinto "Trash"; stop; } #if header :contains "addressIdontwant(a)repliedtoo.tld" { # stop; #} vacation # Reply at most once a day to a same sender :days 1 :subject "Changes to email addresses effective Jan 01/15" # List of recipient addresses which are included in the auto replying. # If a mail's recipient is not on this list, no vacation reply is sent for it. :addresses ["user(a)repliedtoo.tld"] This is on a Dovecot 1.x system that is slated for an upgrade soon. -- Harondel J.

Dovecot Oy merger with Open-Xchange AG
by Timo Sirainen 03 Apr '15

03 Apr '15

Hi all, Today I can finally announce that Dovecot Oy company has merged with Open-Xchange AG. This helps us to get more Dovecot developers, support people and so on. Most importantly, eventually it should allow me to get back to doing what I like the most: Designing new and interesting stuff for Dovecot and perfecting the old stuff :) OX is a great match to Dovecot going forward. They also really like open source and share our plans for the future. Nothing big will change as a result of this merger: Dovecot will stay Dovecot with its own name and release schedules. We're not going to force OX and Dovecot to be the same product, other than having a somewhat deeper integration between them. Here are the press release links about it: http://www.dovecot.fi/open-xchange-and-dovecot-announce-merger-to-create-wo… http://www.open-xchange.com/dovecot http://www.open-xchange.com/announcements/18

EL6 EE package dependencies
by Will Yardley 03 Apr '15

03 Apr '15

I've been trying to upgrade Dovecot-ee package (on EL6/x86_64) from 2.2.15.8-1 to 2.2.16.2-1. It's complaining on these two dependencies: liblz4.so.1 libtextcat.so.0 These would both seem to be related to plugins, and don't seem to be required as package dependencies by the RPM from what I can see from the SRPM. Anyone know what packages I need to satisfy these dependencies?

Install process breaks its self by design
by Merlin at Desktop Masters 02 Apr '15

02 Apr '15

Greetings, I just tried to install Dovecot for the first time. It was on a virgin Ubuntu/Debian server (Version: 1:2.2.9-1ubuntu5) and the install failed. After a bit of struggling I worked out that the install fails BY DESIGN. Spoke about this with a few people and we decided it was best to report this issue and request that you redesign the packing so it does not fail. The reason it fails is as follows... When you install it asks you if you want to use self signed certificates. I have certificates so I said, "No". At the end of the install the script tries to start dovecot. It cannot because the service does not have certificates so it fails. This causes the script to abort and the other packages not to install and breaks the install process. I had to purge dovecot, then install it with the self signed certificates. So we have 2 issues here. 1. Why allow people to not install certificates if it is just going to break the install and confuse them. 2. Why are you starting the service right after install when dovecot clearly requires manual configuration as part of the setup. I recommend you resolve this by NOT starting the service as part of the install unless it is an upgrade and the service was already running. ~ Merlin

Migrating from Cyrus to Dovecot
by Miloslav Hůla 31 Mar '15

31 Mar '15

Hi, we are migrating from Cyrus 2.3.7 to Dovecot 2.2.13. We have ~7000 maildirs with ~500GB. Our goal is to do the migration without users have notice and with the shortest service downtime. The users use IMAP (with shared folders and ACL), POP3 and sieve filters. As a first choice, we tried the Dovecot's dsync tool. First tests were great, but we are not able to change the Cyrus auth backend for migration. Moreover, this migration seems too slow for us. As a second try, we tried the cyrus2dovecot migrating Perl scripts (and their derivates) from Wiki2. More or less they works but we found we need more control during the migration. So, as a third try, we wrote own migrating scripts. And thanks to the cyrus2dovecot it wasn't too much complicated. And there are my questions: A) Files and dirs timestamps The mtime of email file is important as an internal date as I found on Wiki2. But what about timestamps of cur/new/tmp directories or Dovecot's internal files line dovecot-uidlist? Do they play some role here? B) The 128 bit mailbox UID The Wiki2 speaks about 128 bit mailbox UID at first line of dovecot-uidlist. Cyrus preserves only 64 bit UID. Is this mailbox UID required by Dovecot? If so, can we use 0000000000000000501100008c4a11c1 (Cyrus UID padded by zeros)? C) Format of dovecot-uidlist records Wiki2 shows two examples: 25006 :1276528487.M364837P9451.kurkku,S=1355,W=1394:2, 25017 W2481 :1276533073.M242911P3632.kurkku:2,F Which format is preferred? Or what the benefits are? D) Converting between CRLF and LF If I understand correctly, Dovecot stores emails with LF only. We have all emails with CRLF now on Cyrus and converting them to LF only is a little more time consuming. Is there any benefit to do that? Or can we live with 'mail_save_crlf' without problems? E) POP3 backend I found many informations about IMAP internals but few on POP3 internals. What do I need to do POP3 migration transparent for user? Many thanks for any answers. Regards, Milo

Hello list, I have been struggling with establishing a working installation of dovecot with mySQL quota support. I have not been able to find a guide or tutorial that works for the current revisions of software I have at my disposal. Most notably, the error I see in the mail log is as follows : Mar 23 00:55:31 host dovecot: lmtp(328): Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so Mar 23 00:55:31 host dovecot: lmtp(328): Error: dlopen(/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so) failed: /usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: undefined symbol: command_unregister Mar 23 00:55:31 host dovecot: lmtp(328): Fatal: Couldn't load required plugins I have attached my dovecot -n output. The installed revision of dovecot is 2.2.9 on ubuntu 14.04.02 LTS. Thank you in advance. --

sieve rule for "header don't exist"
by Reindl Harald 30 Mar '15

30 Mar '15

is there a way to expresse when the header "X-Spam-Status" *do not* exist move the message to a different folder? :contains, :matches and :is are not helpful here background: the spamass-milter option -B is lacking the spamassassin headers in case of milter-rejects and via sendmail generated BCC while flagged messages contain the headers - so it would be nice to move the rejected ones to a subfolder "REJECTED" instead into the inbox

v2.2.16 released
by Timo Sirainen 28 Mar '15

28 Mar '15

http://dovecot.org/releases/2.2/dovecot-2.2.16.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.16.tar.gz.sig A few fixes and some imapc improvements since the release candidate. * dbox: Resyncing (e.g. doveadm force-resync) no longer deletes dovecot.index.cache file. The cache file was rarely the problem so this just caused unnecessary slowness. * Mailbox name limits changed during mailbox creation: Each part of a hierarchical name (e.g. "x" or "y" in "x/y") can now be up to 255 chars long (instead of 200). This also reduces the max number of hierarchical levels to 16 (instead of 20) to keep the maximum name length 4096 (a common PATH_MAX limit). The 255 char limit is hopefully large enough for migrations from all existing systems. It's also the limit on many filesystems. + director: Added director_consistent_hashing setting to enable consistent hashing (instead of the mostly-random MD5 hashing). This causes fewer user moves between backends when backend counts are changed, which may improve performance (mainly due to caching). + director: Added support for "tags", which allows one director ring to serve multiple backend clusters with different sets of users. + LMTP server: Added lmtp_user_concurrency_limit setting to limit how many LMTP deliveries can be done concurrently for a single user. + LMTP server: Added support for STARTTLS command. + If logging data is generated faster than it can be written, log a warning about it and show information about it in log process's process title in ps output. Also don't allow a single service to flood too long at the cost of delaying other services' logging. + stats: Added support for getting global statistics. + stats: Use the same session IDs as the rest of Dovecot. + stats: Plugins can now create their own statistics fields + doveadm server: Non-mail related commands can now also be used via doveadm server (TCP socket). + doveadm proxying: passdb lookup can now override doveadm_port and change the username. + doveadm: Search query supports now "oldestonly" parameter to stop immediately on the first non-match. This can be used to optimize: doveadm expunge mailbox Trash savedbefore 30d oldestonly + doveadm: Added "save" command to directly save mails to specified mailbox (bypassing Sieve). + doveadm fetch: Added body.snippet field, which returns the first 100 chars of a message without whitespace or HTML tags. The result is stored into dovecot.index.cache, so it can be fetched efficiently. + dsync: Added -t <timestamp> parameter to sync only mails newer than the given received-timestamp. + dsync: Added -F [-]<flag> parameter to sync only mails with[out] the given flag/keyword. + dsync: Added -a <mailbox> parameter to specify the virtual mailbox containing user's all mails. If this mailbox is already found to contain the wanted mail (by its GUID), the message is copied from there instead of being re-saved. (This isn't efficient enough yet for incremental replication.) + dsync: -m parameter can now specify \Special-use names for mailboxes. + imapc: Added imapc_features=gmail-migration to help migrations from GMail. See http://wiki2.dovecot.org/Migration/Gmail + imapc: Added imapc_features=search to support IMAP SEARCH command. (Currently requires ESEARCH support from remote server.) + expire plugin: Added expire_cache=yes setting to cache most of the database lookups in dovecot index files. + quota: If overquota-flag in userdb doesn't match the current quota usage, execute a configured script. + redis dict: Added support for expiring keys (:expire_secs=n) and specifying the database number (:db=n) - auth: Don't crash if master user login is attempted without any configured master=yes passdbs - Parsing UTF-8 text for mails could have caused broken results sometimes if buffering was split in the middle of a UTF-8 character. This affected at least searching messages. - String sanitization for some logged output wasn't done properly: UTF-8 text could have been truncated wrongly or the truncation may not have happened at all. - fts-lucene: Lookups from virtual mailbox consisting of over 32 physical mailboxes could have caused crashes.

postfix sasl -> haproxy -> dovecot auth
by Edgaras Lukoševičius 28 Mar '15

28 Mar '15

Hello, is it possible to configure configure haproxy to work with postfix sasl and dovecot auth like this: clients -> 25:postfix -> 20025:haproxy -> 20025:auth-backend-1, 20025:auth-backend-2 The configuration I have now gives me this error randomly: 535 5.7.8 Error: authentication failed: Connection lost to authentication server This is probably because haproxy change servers while session is still active (postfix sasl don’t establish new connection to auth service every time new auth request arrives) Note that haproxy is between postfix and dovecot and is not facing clients directly, so there is no way to keep persistent connections by client ip. # POSTFIX smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_exceptions_networks = smtpd_sasl_local_domain = smtpd_sasl_path = inet:127.0.0.1:20025 smtpd_sasl_security_options = noanonymous smtpd_sasl_tls_security_options = $smtpd_sasl_security_options smtpd_sasl_type = dovecot # HAPROX frontend postfix-sasl bind 127.0.0.1:20025 default_backend dovecot-auth backend dovecot-auth mode tcp option tcplog option srvtcpka hash-type consistent balance roundrobin server mail-backend-1 31.220.19.52:20025 check server mail-backend-2 31.220.19.53:20025 check

For example, a mail reader that does local manipulation of mbox files rather than via IMAP. This log message is more or less saying that the indices are out of sync with respect to the mailbox, and the message that it expected to find at a file offset is not there anymore. > Mar 26 09:40:07 raspberrypi dovecot: imap(info): Panic: file > mbox-sync.c: line 1286 (mbox_sync_handle_eof_updates): assertion failed: > (trailer_size <= 2) This, though, should not happen. Your version of dovecot is rather old, so maybe an update will solve this. Joseph Tam <jtam.home(a)gmail.com>

Re: Error: open() failed with file /var/vmail/... Too many open files

I've already tried creating etc/default/dovecot chmod +x it and inside put ulimit but didn't work. Also i've tried to put the ulimit into the /etc/init.d/dovecot linked file but i found still 1024 the limit kn dovecot.

You need to put the ulimit commands somewhere in the init script. Or perhaps adding the ulimit command to /etc/default/dovecot would work. I don't know what's the correct Ubuntu way to do it.

Courier-dovecot migration issue: Forward and Junk flags
by Dennis Højgaard 27 Mar '15

27 Mar '15

Hello.. Another courier -> dovecot migrater here.. I ham having a bit of trouble converting the courier maildir correctly, or actually i'm almost there. The only thing i experience is that forwarded messages and messages marked as junk (in thunderbird) are downloaded again (i am using thunderbird and caching) after running the courier-dovecot-migrate.pl script and connecting to the newly configured dovecot imap server.. So i think that the Forward and Junk flag is not being converted..

IMAP ANNOTATE Extension RFC5257: priority on roadmap
by Florian Sager 27 Mar '15

27 Mar '15

Hi Timo, congrats to the merger with OX. Currently the implementation of RFC 5257, ANNOTATE-EXPERIMENT-1, has only low priority on http://wiki2.dovecot.org/Roadmap I want to explain a scenario that would benefit from annotation support to - maybe - increase the priority in your roadmap: I'm currently working on a project to publish bank customer related documents inside a banking webinterface (they call it 'postbox'). There are different requirements that would be satisfied very well by an IMAP server as data storage/provider for a long term email/document archive inside the bank. Annotations would be necessary to tag emails with customer numbers and document IDs to allow a delayed grouping of several emails by such identifiers (message IDs may not be available for references so annotations have to be used to compute references indirectly). Same for sorting and filtering by customer number or account number. I would highly appreciate if you at Dovecot could increase the priority of ANNOTATE in your roadmap.

Error "Next message unexpectedly lost from mbox file"
by BehrensM 26 Mar '15

26 Mar '15

Hi, i am the new one;) - and my first post is about a problem i ran into. I installed a mailserver on a RaspberryPi. It works mostly well, using dovecot 2.1.7. (exim4 4.8 (not in use, smtp direct to Provider), fetchmail 6.3.21, RasPi 3.12.28+, Roundcube (no version known) - the whole system went through an apg-get update/uppgrade this night to look if a known problem already been fixed. When getting bigger Attachments (not sure if it occurs by smaller too, but bigger attachments are normally "to open" and often fail) Not all of them, but much. Unpredictable when it occurs. These Attachments are shown with less size in the Mailclient (Thunderbird actual version). In Roundcube they are shown to small, too. But it looks as the mail IS "fullsized" on the lokal Mailserver: When i use Roundcube and try to open an x00kB .zip, Roundcube starts to get the whole xyMB (real size) .zip-file, even when disconnected from internet. Thunderbird behaves different, doesnt load the full file, so "ignore" is no option;) And yes, i always dont like that option:) Beside the lokal mailserver-account(s) there is/are pulled Mails via imap direct from the mailprovider, the "old" solution which shall be replaced by the new mailserver. imap direct from provider shows the mails/Attachments in corrects size an opening works. Only using the local mailserver fails. In the log-files i found (i quote a part in which - cronjob matching - one of these defect mails was pulled): In Syslog: Mar 26 09:40:01 raspberrypi /USR/SBIN/CRON[26696]: (info) CMD (/usr/bin/fetchmail -s --fetchsizelimit 0 --fetchlimit 0 --limit 0 --timeout 300) Mar 26 09:40:05 raspberrypi dovecot: imap(info): Error: Next message unexpectedly lost from mbox file /home/info/mail/.INBOX at 1066141935 (cached) Mar 26 09:40:05 raspberrypi dovecot: imap(info): Error: read(/home/info/mail/.INBOX) failed: Invalid argument (FETCH for mailbox INBOX UID 1247) Mar 26 09:40:05 raspberrypi dovecot: imap(info): Disconnected: Internal error occurred.

Lazy_expunge issue...
by giorgio paolucci 26 Mar '15

26 Mar '15

Hello everybody, I have a question about lazy_expunge plugin. I set up Dovecot with lazy_expunge plugin on a Debian Wheezy machine; I setup also a global acl to keep .expunged namespace readonly for all users. Imap client is Horde Webmail Edition 5.2.3 When I try to delete folders containing subfolders, lazy_expunge copies into expunged private namespace only the upper level folder. The subfolder and all messages inside it are lost. Quota is also corrupted (subfolder messages are still accounted in the Message counter and disk quota) and a recalc is needed to fix. Problem can be reproduced this way: 1)Create with horde a folder "extern" 2)Create a subfolder "extern/subfolder" 3) copy some messages into extern and some into subfolder (in my test 5 messages each) 4) verify quota usage: root@gold:# doveadm quota get -u testimap2.csia(a)unipd.it Quota name Type Value Limit % User quota STORAGE 4 1126400 0 User quota MESSAGE 10 - 0 3)Delete extern with option to delete all subfolders. 4)verify that all folders and messages have been deleted 5)verify that only extern folder has been copied into .expunged namespace and verify that quota still reports the 5 messages that were in subfolder: root@gold:# doveadm quota get -u testimap2.csia(a)unipd.it Quota name Type Value Limit % User quota STORAGE 2 1126400 0 User quota MESSAGE 5 - 0 6) recalc quota and check again that quota has benne corrected: # doveadm quota recalc -u testimap2.csia(a)unipd.it root@gold:# doveadm quota get -u testimap2.csia(a)unipd.it Quota name Type Value Limit % User quota STORAGE 0 1126400 0 User quota MESSAGE 0 - 0 Is there anything I am missing? Thanks in advance. Best regards.

Re: Dovecot Oy merger with Open-Xchange AG
by Patrick Coffin 25 Mar '15

25 Mar '15

To Timo and the Dovecot guys - congratulations! I'm sure this merger with OpenXchange is going to provide you with a lot of resources and opportunities. As a longtime user of dovecot, I do have a few concerns. I wonder if you can answer some questions for me. You say that OpenXchange really likes open source and shares your plans for the future. Is this a commitment that future versions core dovecot product will remain free and truly open source? According to Wikipedia (http://en.wikipedia.org/wiki/Open-Xchange#Licensing <http://en.wikipedia.org/wiki/Open-Xchange#Licensing>) , OpenXchange's backend is GPL'd, but the front-end is not - it's released under "Creative Common's Share Alike, Non Commercial, Attribution". The article points out: "The restriction to Non Commercial in the Creative Commons license for the Frontend restricts re-distribution to third parties, i.e. hosted deployments for third parties. However, since the front-end license prohibits commercial re-distribution, the software is neither free software nor open source software since the definitions of both require such re-distribution to be permitted" Do you expect that dovecot is moving in that direction? Here's why I'm asking: As a hosted email provider, I've long used dovecot, and been quite happy with it. But I have some concerns, as is common when any popular open source project gets acquired by a commercial entitiy. The current dovecot license is a mixture of the MIT and LGPL licenses. Will this remain? Or is dovecot going to go the way of OpenXchange licensing? What about other pieces of the dovecot ecosystem, such as the Object Storage plugin - will that remain closed source and proprietary? Or will you follow the lead of companies like RedHat and be truly open source? Is there a possibility that future versions of dovecot that contain what we might consider core features will be available only in the commercial version of the product? If I base a part of my business on a piece of software I've been running for the last 10 years, am I going to find myself in trouble in a year or two, when some new version of dovecot comes out with changes that I need, and I have to move to a commercial product, which I may or may not be able to afford? I'd love to hear that you're going to be following a model like RedHat did when they acquired GlusterFS and created the RedHat Storage Server. Gluster development is still going strong, and still completely open source. But they make money from people like me who know that by buying a contract, we can get the kind of support we need for such a critical part of our infrastructure. Again, congratulations and, as always, thanks for all the hard work creating dovecot in the first place. Patrick

Upgrading a dovecot director configuration?
by Will Rouesnel 25 Mar '15

25 Mar '15

Is Dovecot Director compatible across Dovecot versions? i.e. 2.0.x to 2.1.x or 2.2.x? I have a 6 host cluster in a director configuration which is getting somewhat aged, but it would be very beneficial if the director hosts could be upgraded seamlessly. Is such a thing possible, or will their be compatibility issues? Would a workaround be possible (i.e. migrate to a user system which enforces proxy destinations by another means, then do an upgrade?)

Fixing broken UTF-8 handling with MySQL driver
by Felix Zandanel 23 Mar '15

23 Mar '15

Hi, I noticed that dovecot's MySQL driver doesn't play well with UTF-8 encoded strings. I presume this issue has been around for a while. However, it still fails with the current release candidate 2.2.16-rc1. I have been using the sieve extdata plugin with a MySQL-backed dict to retrieve a folder name that is then passed to fileinto: fileinto :create "${extdata.folder_name_drafts}"; Whenever this dict returned a string with non-7byte characters, a line such as the following popped up in sieve.log. (This example query should return "Entwürfe".) error: folder name specified for fileinto command is not utf-8: Entw?rfe. Although my MySQL installation is set up to use UTF-8 as the default charset on every level (config, database, table and field), and the character_set_* runtime variables all yield the value "utf8", it still seems that the mysql client library must be instructed to actually use UTF-8 explicitly. Adding the following statement to driver_mysql_connect() fixes the issue for me: mysql_options(db->mysql, MYSQL_SET_CHARSET_NAME, "utf8"); I checked this against mysql 5.5.41. Regards, Felix

[PATCH] increase fd_limit to max_client_limit automatically
by Lauri Tirkkonen 23 Mar '15

23 Mar '15

Hi, with a low soft limit on file descriptors, dovecot 2.2.15 warns on startup: Warning: fd limit (ulimit -n) is lower than required under max. load (256 < 1000), because of default_client_limit It could try increasing the limit first, and only report the warning if that fails. I'm attaching a patch that does just this. Without the patch, the soft fd limit is kept at whatever it was on dovecot startup: % pfexec plimit $(pgrep dovecot) 18737: /opt/niksula/sbin/dovecot resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 10240 unlimited coredump(blocks) unlimited unlimited nofiles(descriptors) 256 65536 vmemory(kbytes) unlimited unlimited and with patch applied, it's increased to max_client_limit: % pfexec plimit $(pgrep dovecot) 18775: /opt/niksula/sbin/dovecot resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 10240 unlimited coredump(blocks) unlimited unlimited nofiles(descriptors) 1000 65536 vmemory(kbytes) unlimited unlimited It should probably be increased to higher than that to account for fds other than client sockets, but I don't have insights into that. -- Lauri Tirkkonen Niksula systems specialist

The drawback of getting thing in digest form -- you look like a boob when answering late. I defer to Steffen's superior knowledge. Joseph Tam <jtam.home(a)gmail.com>

2.2.16 link failure on FreeBSD 10.1, with patch
by Jan Mikkelsen 22 Mar '15

22 Mar '15

Hi, Compiling on FreeBSD 10.1 gives linker errors when linking test-message-snippet. The underlying problem is that libiconv appears on the actual linker line after libcharset.a, which leads to unresolved libiconv symbols. This build process worked fine with 2.2.15. The patch below to src/lib-charset/Makefile.in resolves the problem for me and seems broadly correct. libcharset.a does depend on libiconv so it should probably be declared that way. There is probably a more correct way to make the patch to Makefile.am, but I don't really use automake. Hopefully helpful to someone. Jan Mikkelsen.

Transitioning from version 1 to version 2
by Steve Matzura 21 Mar '15

21 Mar '15

I'm wrestling with transitioning from a 1.0.15 system to a 2.2.25 system. The old dovecot.conf cannot be dropped into position on the new system because so many config options and symbols have changed. It seems every time I change something to match the new formats, I break something else! Anyone out there have maybe half an hour to spare to look at my old and new files to help me whip them into shape?

FreeBSD ZFS maildir to mdbox
by Roland van Laar 21 Mar '15

21 Mar '15

Hello, I'm converting my mailbox from Maildir to mdbox.. The Maildir is from an 1.2 server. The new server is a virtual FreeBSD ZFS server. The conversion is not working, I'm getting either segfaults or the sync just quits with errors. I also did set with mmap_disable=yes. This didn't resolve the problem. How can I fix this? The same conversion on a virtual ubuntu 14.04 box works with mentions of "filename has the wrong S value" and Corrupted index errors. The FreeBSD errors and dovecot -n are included below: dsync(vagrant): Error: read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) dsync(vagrant): Error: Maildir filename has wrong S value, renamed the file from ./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa to ./Maildir/cur/1296038598.29562.mail.micite.net,S=20640:2,Sa dsync(vagrant): Error: Corrupted index cache file ./Maildir/dovecot.index.cache: Broken physical size for mail UID 475 dsync(vagrant): Error: write(/home/vagrant/mdbox/storage/m.12) failed: Invalid argument dsync(vagrant): Error: copy: i_stream_read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) dsync(vagrant): Error: read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) (uid=475, box=INBOX) dsync(vagrant): Error: Mailbox INBOX: read(msg input) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) dsync(vagrant): Error: read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) (uid=475, box=INBOX) dsync(vagrant): Panic: file mail-index-transaction-update.c: line 964 (mail_index_update_ext): assertion failed: (seq > 0 && (seq <= mail_index_view_get_messages_count(t->view) || seq <= t->last_new_seq)) Abort (core dumped) (gdb) core doveadm.core Core was generated by `doveadm'.

Strange empty folders 1 1 1 1 1
by Samuel Williams 20 Mar '15

20 Mar '15

I just updated to the latest dovecot from 1.2 and it has been working great for most of my clients. But one client,who is using Outlook, has found that hundreds of folders have been created, e.g. admin@domain Deleted Items 1 admin@domain Deleted Items 1 1 admin@domain Deleted Items 1 1 1 .... admin@domain Deleted Items 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 This appears to be affecting all folders in his account, across multiple accounts for his domain. It isn't affecting any other user, even other users using outlook. All the folders are empty. Just wondering if anyone has any suggestions or ideas why this is happening. Thanks Samuel
