[Dovecot] LMTP ignoring tcpwrappers
by Harm Weites 23 Jan '12

23 Jan '12

Hello, we want to use dovecot LMTP for efficient mail delivery from our MX servers (running postfix 2.8) to our storage servers (dovecot 2.0.17). However, the one problem we see is the lack of access control when using LMTP. It apears that every client in our network who has access to the storage machines can drop a message in a Maildir of any user on that storage server. To prevent this behaviour it would be nice to use libwrap, just as it can be used for POP3/IMAP protocols. This, however, seems to be impossible using the configuration as mentioned on the dovecot wiki: login_access_sockets = tcpwrap service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } This seems to imply it only works for a login, and LMTP does not use that. The above works perfectly when trying to block access to IMAP or POP3 in /etc/hosts.deny, though a setting for LMTP is simply ignored. Is there a configuration setting needed for this to work for LMTP, or is it simply not possible (yet) and does libwrap support for LMTP requires a patch? Any help is appreciated. Regards, Harm

IMAP proxy could be a problem if the user had opened more than 10 (unique) mailboxes. The proxy would keep this connection open until a timeout, and after some time, could accumulate more connections than your limit. The lack of proxy could solve your problem if for some reason your webmail software is not closing the IMAP connection properly (I assume IMP does a connect/authenticate/IMAP command/logout for every webmail operation). Every connection (even to the same mailbox) would open up a new connection. The proxy software will recognize the reconnnection and funnel it through its cached connection. You can lsof the user's IMAP processes (or troll through /proc/{imap-process} or what you have) to figure out which mailboxes it has opened. On my system, file descriptor 9 and 11 gives you the names of the index files that indicate which mailboxes are being accessed. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Clients show .subscriptions folder
by Mark Sapiro 21 Jan '12

21 Jan '12

Since upgrading from dovecot-2.1.rc1 to dovecot-2.1.rc3, some clients are showing a .subscriptions file in the user's mbox path as a folder. Some clients such as T'bird on Mac OS X create this file listing subscribed mbox files. Other clients such as T'bird on Windows XP show this file as a folder in the folder list even though it cannot be accessed as a folder (dovecot returns CANNOT Mailbox is not a valid mbox file). I think this may be a result of uncommenting the inbox namespace in conf.d/10-mail.conf <http://hg.dovecot.org/dovecot-2.1/rev/2c8d39467f21>. Is there a way to supress exposing this file to clients that don't use it? # dovecot -n # 2.1.rc3: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-8.1.14.el5 i686 CentOS release 5 (Final) auth_mechanisms = plain apop login auth_worker_max_count = 5 mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl dotlock namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /usr/local/etc/dovecot.passwd driver = passwd-file } passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </etc/httpd/conf/ssl/combined.crt ssl_key = </etc/httpd/conf/ssl/www.grizz.org.key userdb { driver = passwd } protocol imap { mail_max_userip_connections = 30 } # -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] Performance of Maildir vs sdbox/mdbox
by Lee Standen 20 Jan '12

20 Jan '12

Hi Guys, I've been desperately trying to find some comparative performance information about the different mailbox formats supported by Dovecot in order to make an assessment on which format is right for our environment. This is a brand new build, with customer mailboxes to be migrated in over the course of 3-4 months. Some details on our new environment: * Approximately 1.6M+ mailboxes once all legacy systems are combined * NetApp FAS6280 storage w/ 120TB usable for mail storage, 1TB of FlashCache in each controller * All mail storage presented via NFS over 10Gbps Ethernet (Jumbo Frames) * Postfix will feed new email to Dovecot via LMTP * Dovecot servers have been split based on their role - Dovecot LDA Servers (running LMTP protocol) - Dovecot POP/IMAP servers (running POP/IMAP protocols) - LDA & POP/IMAP servers are segmented into geographically split groups (so no server sees every single mailbox) - Nginx proxy used to terminate customer connections, connections are redirected to the appropriate geographic servers * Apache Lucene indexes will be used to accelerate IMAP search for users Our closest current live configuration (Qmail SMTP, Courier IMAP, Maildir) has 600K mailboxes and pushes ~ 35,000 NFS operations per second at peak Some of the things I would like to know: * Are we likely to see a reduction in IOPS/User by using Maildir alone under Dovecot? * What kind of IOPS/User reduction could we expect to see under mdbox? * If someone can give some technical reasoning behind why mdbox does less IOPS than Maildir? I understand some of the reasons for the mdbox IOPS question, but I need some more information so we can discuss internally and make a decision as to whether we're comfortable going with mdbox from day one. We're very familiar with Maidlir, and there's just some uneasiness internally around going to a new mail storage format. Thanks!

When I googled this error there was a thread on this list from May 2011 that indicated one would need one connection per user per subscribed folder. However, I know that user doesn't have 10 folders, let alone 10 subscribed folders! I can increase, it but it's not going to scale well. And there are people on this list with many 1000x users than I have - so how do they deal with that? 127.0.0.1 is obviously webmail (IMP5). So, how/why am I seeing this, and should I be concerned?

[Dovecot] shared folder files not displaying in thunderbird
by Eric Broch 19 Jan '12

19 Jan '12

Hello, I have dovecot installed with the configuration below. One of the subfolders created (using the email client) under the '/home/vpopmail/domains/mydomain.com/shared/projects' share no longer (it used to) displays the files located in it. There are about 150 folders under the '/home/vpopmail/domains/mydomain.com/shared/projects' share all of which display the files located in them, the one mentioned used to display the contents but no longer does. What would be the reason that one folder would no longer display existing files in the email client (Thunderbird) and the other folders would? And, how do I fix this? I've already tried unsubscribing and resubscribing the folder. This did not work. Would it now be simply a matter of unsubscribing the folder, deleting the dovecot files, and resubscribing to the folder?

[Dovecot] Quota won't work

I tried to set a quota setting. I installed dovecot with newest version, patched it and started it. dovecot -n: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.3 ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_listen: 143 ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%n/Maildir mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 namespace: type: private inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)opsys.de mail_plugins: sieve quota log_path: auth default: mechanisms: plain login verbose: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail /etc/dovecot/dovecot-sql.conf: driver = mysql connect = host=127.0.0.1 dbname=mailserver user=mailuser password=****** default_pass_scheme = PLAIN-MD5 password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; user_query = SELECT CONCAT('/var/mail/', maildir) AS home, CONCAT('*:bytes=', quota) AS quota_rule \ FROM virtual_users WHERE email='%u' virtual_users has this: CREATE TABLE IF NOT EXISTS `virtual_users` ( `id` int(11) NOT NULL AUTO_INCREMENT, `domain_id` int(11) NOT NULL, `password` varchar(32) NOT NULL, `email` varchar(100) NOT NULL, `quota` int(11) NOT NULL DEFAULT '629145600', PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`), KEY `domain_id` (`domain_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Also postfix is installed with this (not the hole cfg): virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_limit_inbox = no virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql-quota.cf virtual_mailbox_limit_override = yes virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_maildir_extended = yes virtual_maildir_limit_message = "The user you are trying to reach is over quota." virtual_maildir_limit_message_maps = mail:/etc/postfix/mysql-quota.cf virtual_overquota_bounce = yes /etc/postfix/mysql-quota.cf: user = mailuser password = ****** hosts = 127.0.0.1 dbname = mailserver query = SELECT quota FROM virtual_users WHERE email='%s' I changed the quota of my mail account to 40, so 40Byte should be the maximum. My account is at a size of 600KB now. I still recieve mails, also they will be saved without errors. /var/log/mail.log says nothing to quota, just normal recieve and store entries. What to fix? -- Markus Fritz Administration opsys.de

[Dovecot] LMTP Logging
by Mark Moseley 18 Jan '12

18 Jan '12

Just had a minor suggestion, with no clue how hard/easy it would be to implement: The %f flag in deliver_log_format seems to pick up the From: header, instead of the "MAIL FROM:<...>" arg. It'd be handy to have a %F that shows the "MAIL FROM" arg instead. I'm looking at tracking emails through logs from Exim to Dovecot easily. I know Message-ID can be used for correlation but it adds some complexity to searching, i.e. I can't just grep for the sender (as logged by Exim), unless I assume "MAIL FROM" always == From:

[Dovecot] v2.1.rc3 released
by Timo Sirainen 18 Jan '12

18 Jan '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc3.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc3.tar.gz.sig Whops, rc2 was missing a file. I always run "make distcheck", which should catch these, but recently it has always failed due to clang static checking giving one "error" that I didn't really want to fix. Because of that the distcheck didn't finish and didn't check for the missing file. So, anyway, I've made clang happy again, and now that I see how bad idea it is to just ignore the failed distcheck, I won't do that again in future. :)

[Dovecot] Dovecot unable to locate mailbox
by Jason X, Maney 18 Jan '12

18 Jan '12

Dear all, I hope someone can point me in the right direction. here. I have setup my Dovecot v2.0.13 on Ubuntu 11.10. The logs tells me that the mail location has failed as follows: ========= Jan 16 14:18:16 myservername dovecot: pop3-login: Login: user=<userA>, method=PLAIN, rip=aaa.bbb.ccc.ddd, lip=www.xxx.yyy.zzz, mpid=1360, TLS Jan 16 14:18:16 myservername dovecot: pop3(userA): Error: user molla: Initialization failed: mail_location not set and autodetection failed: Mail storage autodetection failed with home=/home/userA Jan 16 14:18:16 myservername dovecot: pop3(userA): Error: Invalid user settings. Refer to server log for more information. ========= Yet my config also come out strangely as below: ========= root@guyana:~# dovecot -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 3.0.0-12-server x86_64 Ubuntu 11.10 passdb { driver = pam } protocols = " imap pop3" ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } root@guyana:~# ========= My mailbox location setting is as follows: ========= cat conf.d/10-mail.conf |grep mail_location # path given in the mail_location setting. # mail_location = maildir:~/Maildir # mail_location = mbox:~/mail:INBOX=/var/mail/%u # mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n mail_location = maildir:~/Maildir # explicitly, ie. mail_location does nothing unless you have a namespace # mail_location, which is also the default for it. ========= I am wondering how best to work around this Dovecot problem. Please help. Regards Jason.
