Quotas not working after reboot
by Edgaras Lukoševičius 28 Apr '15

28 Apr '15

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. Before reboot it was like this: # doveadm -D quota get -u test1(a)testdomain1.tld doveadm(root): Debug: Loading modules from directory: /usr/lib64/dovecot doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib64/dovecot/doveadm 03NB0d9erYBwhnzXhbS66fLDMU8v4ZiCDQDM3tDHCKme4ujpHy/lRk33305AIO9UXtgHGFyJYSpcVgoVnXJQGpJBphGvkAF4XI1JGx83Dtlb44wgJ8ZBgOm4qSNOoQIXKv0NO35EwUohtYBMlDJKPRUTwRF93tW7RsfWZGVNi4Eo5k616Tn4ooU3JMXkQA8LZ5zzLllspBVDbyb4GPAmWiw== root@ovzcloud doveadm(root): Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/doveadm/lib10_doveadm_sieve_plugin.so doveadm(root): Debug: Skipping module doveadm_fts_lucene_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib20_doveadm_fts_lucene_plugin.so: undefined symbol: lucene_index_iter_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(test1(a)testdomain1.tld): Debug: Added userdb setting: plugin/quota=maildir:storage=512000000 doveadm(test1(a)testdomain1.tld): Debug: Added userdb setting: plugin/quota_rule=*:bytes=512000000 doveadm(test1(a)testdomain1.tld): Debug: Effective uid=997, gid=996, home=/home/vmail/t/e/testdomain1.tld/test1/ doveadm(test1(a)testdomain1.tld): Debug: Quota root: name=storage=512000000 backend=maildir args= doveadm(test1(a)testdomain1.tld): Debug: Quota rule: root=storage=512000000 mailbox=* bytes=512000000 messages=0 doveadm(test1(a)testdomain1.tld): Debug: Quota warning: bytes=486400000 (95%) messages=0 reverse=no command=quota-warning 95 test1(a)testdomain1.tld doveadm(test1(a)testdomain1.tld): Debug: Quota warning: bytes=409600000 (80%) messages=0 reverse=no command=quota-warning 80 test1(a)testdomain1.tld doveadm(test1(a)testdomain1.tld): Debug: Quota grace: root=storage=512000000 bytes=25600000 (5%) doveadm(test1(a)testdomain1.tld): Debug: Namespace inbox: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/home/vmail/t/e/testdomain1.tld/test1/ doveadm(test1(a)testdomain1.tld): Debug: maildir++: root=/home/vmail/t/e/testdomain1.tld/test1, index=, indexpvt=, control=, inbox=/home/vmail/t/e/testdomain1.tld/test1, alt= doveadm(test1(a)testdomain1.tld): Debug: Namespace : type=private, prefix=, sep=, inbox=no, hidden=yes, list=no, subscriptions=no location=fail::LAYOUT=none doveadm(test1(a)testdomain1.tld): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= Quota name Type Value Limit % storage=512000000 STORAGE 0 500000 0 storage=512000000 MESSAGE 0 -

[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

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).

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.

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. Thanks, Florian dovecot.conf https://paste.xinu.at/PUsJ/ syslog: > Apr 21 10:52:16 karif dovecot[7849]: imap-login: Disconnected (no auth attempts in 6 secs): user=<>, rip=81.217.47.122, lip=78.46.56.141, TLS handshaking: SSL_accept() failed: error:1407609C:SSL routines:SSL23_GET_CLIENT_HELLO:http request > Apr 21 10:52:16 karif dovecot[7849]: imap-login: Fatal: master: service(imap-login): child 7879 killed with signal 11 (core not dumped - add -D parameter to service imap-login { executable } [last ip=81.217.47.122] > Apr 21 10:52:16 karif kernel: imap-login[7879] segfault at f0 ip 00007fb2b8b1360b sp 00007fff926ffd50 error 4 in libssl.so.1.0.0[7fb2b8af3000+6f000] backtrace: > #0 0x00007f120100260b in ssl3_get_client_hello () from /usr/lib/libssl.so.1.0.0 > #1 0x00007f120100738f in ssl3_accept () from /usr/lib/libssl.so.1.0.0 > #2 0x00007f1201012b36 in ssl3_write_bytes () from /usr/lib/libssl.so.1.0.0 > #3 0x00007f1201906200 in ??

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 }
