[Dovecot] IMAP and POP3 per SSL
by Lamprecht, Andreas 20 Mar '12

20 Mar '12

Hi! I'm new to this list and i could not find a way to search through the already posted articles, so please forgive me if this subject has been discussed before. Our security scanner stumbled over the IMAPs server i've set up recently using dovecot on a RedHat Enterprise 64bit Server. The security scanner found an error regarding a new SSL security leak named "BEAST". The exact error number is CVE-2011-3389. Details can be found here: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3389 "The internet" has some workarounds for this problem. For example, in Apache webserver, you need to set SSLHonorCipherOrder On in apache config. This results in the following C-Code being executed: SSL_CTX_set_options(ctx, SSL_OP_CIPHER_SERVER_PREFERENCE); This setting tells OpenSSL not to honor the Ciper Order sent from the client, but prefer it's own configured set of CipherSuites. According to Qualis SSL Labs ( https://www.ssllabs.com/ssldb/index.html ), a webserver configured with this setting is not affected by that BEAST security leak. Is there a way to implement such a setting into Dovecot, too? I have created a very quick and dirty solution to avoid being listed on our internal security problem's list. This patch is for dovecot 2.0.9 which is included in Redhat Enterprise Linux 6.2: *** src/login-common/ssl-proxy-openssl.c 2010-12-30 10:42:54.000000000 +0100 --- src/login-common/ssl-proxy-openssl.c_1 2012-03-20 09:48:28.359508087 +0100 *************** *** 924,930 **** X509_STORE *store; STACK_OF(X509_NAME) *xnames = NULL; ! SSL_CTX_set_options(ssl_ctx, SSL_OP_ALL | SSL_OP_NO_SSLv2); if (*set->ssl_ca != '\0') { /* set trusted CA certs */ store = SSL_CTX_get_cert_store(ssl_ctx); --- 924,930 ---- X509_STORE *store; STACK_OF(X509_NAME) *xnames = NULL; ! SSL_CTX_set_options(ssl_ctx, SSL_OP_ALL | SSL_OP_NO_SSLv2 | SSL_OP_CIPHER_SERVER_PREFERENCE ); if (*set->ssl_ca != '\0') { /* set trusted CA certs */ store = SSL_CTX_get_cert_store(ssl_ctx); Of course there should be a way to switch this setting on or off, but my C programming skills are rather basic ... So, maybe you have the time to look over it and implement a final solution for the BEAST problem. Greetings Andreas lamprecht

[Dovecot] Problem with sieve
by Cédric Jeanneret 20 Mar '12

20 Mar '12

Hello List! I have a tiny-teeny problem with dovecot + sieve: it seems that the LDA doesn't run sieve, and thus doesn't filter my emails. Here's the sieve configuration: plugin { # Used by both the Sieve plugin and the ManageSieve protocol sieve=/var/local/vmail/%n/dovecot.sieve sieve_dir=/var/local/vmail/%n/sieve sieve_extensions = +notify +imapflags } The managesiege: protocol managesieve { # Specify an alternative address:port the daemon must listen on # (default: *:2000) listen = localhost:2000 managesieve_logout_format = bytes ( in=%i : out=%o ) } (this one is working fine, I can edit the filters through roundcube webmail, and the correct file (/var/local/vmail/%n/dovecot.sieve) is edited) the lda part: protocol lda { postmaster_address = foo(a)bar.com mail_plugins = sieve } I think all is in place to allow dovecot to use sieve... ? One more thing: dovecot --version 1.2.15 Any help will be welcomed :). Thanks in advance ! Cheers, C.

[Dovecot] Per-user IMAP enable - is it possible?
by Alexander Chekalin 20 Mar '12

20 Mar '12

Just wonder if it is possible to enable/disable IMAP4 on Dovecot (2.0.x as far) on per-user basis? The deal is simple: our policy is not to store a lot of mailing on mailserver (the user should store it locally), thus the 'use POP3' approach, but for a vary few users it is permitted to use IMAP4. But users sometimes simple miss the point that some mail clients (e.g. TB) 'prefer' to use IMAP4 first, and afterward I see mailbox full of mailings and no local store of it on user's workstation. Sound too complicated, but setting up two Dovecots is not something I'd love to do as well. Thank you for any ideas, Alexander

I want to run plaintext authentication pop3 and ssl/tls only authentication imap. The 'allow plaintext authentication' configuration directive appears to be global, meaning I will need to run two instances of dovecot for a while. Is that correct, or can this be done on a single instance of dovecot? -- Jeff Simmons jsimmons(a)goblin.punk.net Simmons Consulting - Network Engineering, Administration, Security "You guys, I don't hear any noise.

I'm working with a company that presently has a Linux mailserver which all users have (no shell) accounts on. Mail is accessed via pop3 with plaintext authentication. They want to move to a system using imap with SSL. I'm building them a new server. I'd like to offer both for a while so we can work the bugs out and migrate users over to SSL imap over time. It appears that in order to limit the imap connections to SSL I will need to run two separate instances of Dovecot.

[Dovecot] Creating an IMAP repo for ~100 users need some advice
by Kaya Saman 19 Mar '12

19 Mar '12

Hi, I am currently in the process of setting up an IMAP repository for round 100 users.... Currently the user authentication method is being handled via a Windows Domain Controller. The host OS for Dovecot will either be FreeBSD or CentOS. Would Dovecot be able to authenticate to either the DC directly or would we need to go through LDAP?? Additionally what would be the best method to store the **mail** information? - as in MySQL database or Maildir format; coinciding with this what is the best backup method in order to be able to do 'dump' backups or restore single emails?? Can anyone give me a hand with this? Regards, Kaya

[Dovecot] Accessing maildir snapshots through dovecot
by Laurent CARON 19 Mar '12

19 Mar '12

Hi, I'm currently having a fairly simple setup: - users (real, not virtual) - Maildir storage (over NFS) - 1 namespace I'm currently trying to render the storage snapshots available through dovecot (to allow my users to browse their mail history). dovecot.conf: namespace { inbox = yes location = prefix = INBOX. type = private } I did the following modifications: dovecot.conf: namespace snaps-h0 { prefix = INBOX.EmailBackup.h0. hidden = no list = yes inbox = no location = maildir:/home/.snapshot/hourly.0/%u/Maildir:INDEX=/var/tmp/dovecot/indexes/hourly.0/%u:CONTROL=/var/dovecot/control/hourly.0/%u type = private } Problem: I don't see the content of the inbox folder contained in the snapshots (subfolders are perfectly viewed). Do any of you have a clue on how to render it visible ? Thanks Laurent

[Dovecot] Building Dovecot RHEL RPMs with custom LDAP packages
by Nikolaos Milas 19 Mar '12

19 Mar '12

Hi, We are (still) mainly using CentOS 5 (5.8 x86_64). As CentOS / RHEL 5 standard OpenLDAP packages are rather old (2.3.x), we've been using LTB OpenLDAP packages (http://ltb-project.org/wiki/download#openldap) which get installed in non-standard file system locations. So, I would like to re-build Dovecot packages based on these OpenLDAP libraries, esp. because I see that dovecot RPM packages are built using OpenLDAP v2.3 libraries. I am not much experienced in building RPMs and preparing spec files. In http://dl.atrpms.net/all/dovecot.spec I see: ------------------------------------------------ BuildRequires: openldap-devel, cyrus-sasl-devel ... Obsoletes: %{name}-pgsql < %{epoch}:%{version}-%{release}, %{name}-mysql < %{epoch}:%{version}-%{release}, %{name}-sqlite < %{epoch}:%{version}-%{release}, %{name}-ldap < %{epoch}:%{version}-%{release}, $ Conflicts: %{name}-pgsql > %{epoch}:%{version}-%{release}, %{name}-mysql > %{epoch}:%{version}-%{release}, %{name}-sqlite > %{epoch}:%{version}-%{release}, %{name}-ldap > %{epoch}:%{version}-%{release}, $ ------------------------------------------------ So, I can change the former reference (openldap-devel) to: openldap-ltb-debuginfo, cyrus-sasl-devel Question 1: What other changes should we make in order to specify that we will be using LDAP libraries from: /usr/local/openldap/lib64 and include files from: /usr/local/openldap/include (rather than from /usr/lib64 and /usr/include, respectively, which are the standard file paths used in openldap-devel) Question 2: How the Obsoletes and Conflicts lines should be changed? Question 3: It seems to me (by reading the spec file) that the final Dovecot RPM (and the included executables) does not need any LDAP dynamic library in order to run with LDAP support (because I don't see any dependencies on openldap package). Can somebody please confirm? Any other associated info would be appreciated. Thanks, Nick

http://wiki2.dovecot.org/MailboxFormat/dbox "Expunging a message only decreases the message's refcount. The space is later freed in "purge" step. This is typically done in a nightly cronjob when there's less disk I/O activity. " What happens if there is filesystem hard quota that is exceeded? Will dovecot allow to delete mails to free space without a need to wait for cronjob to do the purge? -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] POP3 Performance

Hi, We actually have a mail hosting solutions with aprox. 100 thousand of email account, where about 90% of a customers use POP3 like email configuration. About a few mounths (we perfomed a lot of migration throught mbox email software to Maildir with dovecot) but i can see that the performance is very poor and receive complaint about delays of autentications of accounts. The solution lives in Metrocluster Netapp storage, filesystem NFS, VMware as a virtualization (the mtas are a virtual machines lives in netapp too) about 4T of data mails and a 10G network connection (betwen mtas and nfs storage) All account information work in LDAP plataform (two servers in replicated mode, no high average or delays detected in this servers) When the traffic have a peak of 1800 concurrent connections POP3, all of service suffer a high load average (about 8 - 20 load average in each dovecot) and authenticacion takes about 2 -10 seconds (in low traffic, autenticacion takes about 60 miliseconds) Also, each dovecot instance lives un MTA server CentOS 5.8 x86_64 with 6G RAM (virtual machine) and share's hardware with a exim instance, like a MTA relay system (autenticated relay) Usage of network have peaks of 80Mbits (all dmz network have 1Gbits of bandwith) Attach of dovecot -n output: # 2.0.18: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-308.1.1.el5 x86_64 CentOS release 5.8 (Final) auth_debug_passwords = yes auth_default_realm = portalplata.cl auth_realms = portalplata.cl auth_verbose = yes auth_verbose_passwords = plain auth_worker_max_count = 100 base_dir = /var/run/dovecot/ debug_log_path = /var/log/dovecot.log default_process_limit = 200 default_vsz_limit = 512 M disable_plaintext_auth = no first_valid_gid = 12 first_valid_uid = 8 lock_method = dotlock login_greeting = Dovecot mta10 mail_cache_min_mail_count = 5 mail_debug = yes mail_fsync = always mail_full_filesystem_access = yes mail_gid = 12 mail_location = maildir:%h/Maildir:INDEX=/data/cache/indexes/%2d/%1u/%2u/%u mail_nfs_storage = yes mail_plugins = " quota" mail_uid = 8 maildir_copy_with_hardlinks = no passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = box from subject quota = maildir } postmaster_address = mail(a)mail.com protocols = imap pop3 sendmail_path = /usr/lib/sendmail service auth { unix_listener auth-userdb { mode = 0600 user = exim } } service imap-login { service_count = 0 } service imap-postlogin { executable = script-login /usr/local/bin/postlogin.sh user = root } service imap { executable = imap imap-postlogin } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } service_count = 0 } service pop3 { process_limit = 1024 } 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 } verbose_proctitle = yes protocol lmtp { mail_plugins = " quota" } protocol lda { mail_plugins = " quota" } protocol imap { imap_capability = mail_max_userip_connections = 10 mail_plugins = " quota autocreate notify quota imap_quota mail_log" plugin { autocreate = Sent Items autocreate2 = Spam autocreate3 = Drafts autocreate4 = Trash autosubscribe = Sent Items autosubscribe2 = Spam autosubscribe3 = Drafts autosubscribe4 = Trash } } protocol pop3 { mail_plugins = " quota quota notify mail_log" pop3_reuse_xuidl = yes pop3_save_uidl = yes pop3_uidl_format = %u } Output of account information in a LDAP: # nettester, email.net, MAIL, USERS, cl dn: uid=nettester,dc=email.net,o=MAIL,o=USERS,c=cl dc: email.net mailMessageStore: /export/mdir/3/12/nettester(a)email.net/Maildir uid: nettester cn: nettester(a)email.net sn: nettester(a)email.net gidNumber: 12 homeDirectory: /export/mdir/3/12/nettester(a)email.net mail: nettester(a)email.net uidNumber: 8 objectClass: mailUser objectClass: posixAccount objectClass: mailSetting loginShell: /bin/false description: enable service: pop3 service: imap service2: webmail mailRate: 200 mailQuota: 1024M deliveryMode: none mailReplyText: .

[Dovecot] Just in time AV scanning
by Kelsey Cummings 16 Mar '12

I'm curious if anyone has any plugins for AV integration directly into dovecot. Our old pop servers have been scanning messges as they're moved from new->cur in the inbox and, at least where user's aren't poping every few seconds, there is occasionally enough time between scanning through the MXs to message retreval to snag a few more virues with updated definitions before they reach customers.

[Dovecot] Problem copying e-mails to IMAP - Dovecot 2.1.2
by Odhiambo Washington 16 Mar '12

16 Mar '12

I have a situation where I need to migrate e-mails from Outlook 2011 (Mac) to Apple Mail. Having looked at all options, I have resorted to the, perhaps, most difficult way: Create folders on the IMAP server, copy e-mails into them from Outlook, connect Apple Mail and do the reverse. However, I have hit a wall. I am running Dovecot 2.1.2 on FreeBSD, with mdbox storage. In my first attempt, I have 1792 messages in the "Sent Items" folder for Outlook. I have tried (3 times) to copy the messages to the IMAP/Sent Items folder, but the process dies at some point. When that happens, Outlook pops a screen saying "IMAP session state is inconsistent, please relogin".

[Dovecot] v2.1.3 released
by Timo Sirainen 16 Mar '12

16 Mar '12

http://dovecot.org/releases/2.1/dovecot-2.1.3.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.3.tar.gz.sig Do not use v2.1.2 with multi-dbox format, it's broken. I didn't notice that a small optimization I did a few days ago broke mdbox in some situations (when mdbox first created a new m.X file, and later in same session saved another message to it). It's quite a high priority for me to run some automated testing before releasing new versions, for example a small imaptest run with mdbox would have caught this. Perhaps the next release will already have the automated testing.

[Dovecot] Another hint from the clue box 8-) imapc/imap proxy user mailbox server location
by Terry Carmen 16 Mar '12

16 Mar '12

I'm running imapproxy as shown at http://wiki2.dovecot.org/HowTo/ImapcProxy. In fact, that's my config in the wiki. 8-) It's been working, but has performance issues when the Exchange server that's hard-coded as imapc_host=xxx.xxx.xxx.xxx doesn't happen to be the user's home exchange server. I'd like to point dovecot at the correct Exchange server based on an LDAP query, and in fact, have an LDAP search that works: DC=example,DC=com (&(objectCategory=person)(objectClass=user)(!(userAccountcontrol:1.2.840.113556.1.4.803:=2))(sAMAccountName=username)) With the exchange server being returned in the msExchHomeServerName property as: /O=example/OU=INT/cn=Configuration/cn=Servers/cn=exchangeservername I believe this should somehow end up in the userdb section, which currently contains "driver = prefetch", but can't seem to figure out specifically what should be there. The only important part is "cn=exchangeservername", which is the machine name and would need to be prepended to example.com to get the fqdn. Can anybody toss me a clue? Once I get it working, I'll update the wiki. Thanks! Terry

[Dovecot] ldapi support
by Nikolaos Milas 16 Mar '12

16 Mar '12

Hi, Quick question: Does Dovecot support ldapi (i.e. via Unix Sockets) connections for LDAP lookups (user, password, auth etc.) or only ldap/ldaps (over TCP)? If yes, how do we specify ldapi://localhost in Dovecot configuration files? Thanks, Nick

[Dovecot] imaptest: performance testing
by Nick Urbanik 16 Mar '12

16 Mar '12

Dear Folks, Using head of imaptest with dovecot 2.1, I am attempting to put a heavy load on the server, with insufficient success. I made 15000 user accounts, put them in to a file, one per line. Then I ran imaptest with ./imaptest userfile=../../imap-test-userlist-15001.txt clients=15001 pass=SECRETPASSWORD But CPU load is only reaching 20. I put an mbox containing 67 messages into ~/mail/dovecot-crlf So what is the best way to put a really heavy load on an imap server? The documentation describes testing correctness of the server without really emphasising performance. I would like to do something like dnsperf, which adds a linearly increasing load until the server is unable to cope. This machine has 24G RAM and 8 cores. I'll be grateful for any constructive suggestions. -- Nick Urbanik http://nicku.org nicku(a)nicku.org GPG: 7FFA CDC7 5A77 0558 DC7A 790A 16DF EC5B BB9D 2C24 ID: BB9D2C24

[Dovecot] Upgrading from 2.0.x to 2.1.x
by Nikolaos Milas 16 Mar '12

16 Mar '12

Hi, A quick question: Are there any incompatibilities in config settings among versions 2.0.x and 2.1.x (and subsequently v2.2.x)? That is, upgrading Dovecot 2.0.x to 2.1.x software, will also require changes of any config settings (as upgrading from v1.x to 2.0.x did)? Thanks, Nick

[Dovecot] Lack of external documentation?
by Steve Campbell 16 Mar '12

16 Mar '12

Firstly, this isn't meant to be critical, and I realize the subject line probably suggest criticism, so... I was sort of forced into using dovecot as my imap/pop server due to upgrading 3 versions of OS on my mail servers. So far, that's not bad. What surprises me is that one of the first things I usually do whenever I start using different software is to purchase a book that seems to suit me. Searching all of the common places like amazon, ebay, etc for manuals turned up little to nothing on dovecot. I'm wondering why and is this so new that people just haven't written books about it yet? The one thing I'm a little critical of, though, is that trying to make heads or tails of dovecot by following the online documentation is a little problematic. I'm constantly jumping to another page and then back to the original page, and for the most part, I just don't know enough about it all yet to know what I'm looking for. Does anyone know of any manuals/books that have been written that might introduce me to most of the stuff in dovecot? So far, the list has been great, but once the "dsync" threads started popping up, I find there's even more I don't know about. Thanks for all the help I've received so far and I think I'm really going to like dovecot. Once I get the hang of it, I'll probably reduce the amount of noise on the list by half. steve campbell

[Dovecot] v2.1.2 released
by Timo Sirainen 16 Mar '12

16 Mar '12

http://dovecot.org/releases/2.1/dovecot-2.1.2.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.2.tar.gz.sig There are a ton of proxying related improvements in this release. You should now be able to do pretty much anything you want with Dovecot proxy/director. This release also includes the initial version of dsync-based replication. I'm already successfully using it for @dovecot.fi mails, but it still has some problems. See http://dovecot.org/list/dovecot/2012-March/064243.html for some details how to configure it. + Initial implementation of dsync-based replication. For now this should be used only on non-critical systems. + Proxying: POP3 now supports sending remote IP+port from proxy to backend server via Dovecot-specific XCLIENT extension. + Proxying: proxy_maybe=yes with host=<hostname> (instead of IP) works now properly. + Proxying: Added auth_proxy_self setting + Proxying: Added proxy_always extra field (see wiki docs) + Added director_username_hash setting to specify what part of the username is hashed. This can be used to implement per-domain backends (which allows safely accessing shared mailboxes within domain). + Added a "session ID" string for imap/pop3 connections, available in %{session} variable. The session ID passes through Dovecot IMAP/POP3 proxying to backend server. The same session ID is can be reused after a long time (currently a bit under 9 years). + passdb checkpassword: Support "credentials lookups" (for non-plaintext auth and for lmtp_proxy lookups) + fts: Added fts_index_timeout setting to abort search if indexing hasn't finished by then (default is to wait forever). - doveadm sync: If mailbox was expunged empty, messages may have become back instead of also being expunged in the other side. - director: If user logged into two directors while near user expiration, the directors might have redirected the user to two different backends. - imap_id_* settings were ignored before login. - Several fixes to mailbox_list_index=yes - Previous v2.1.x didn't log all messages at shutdown. - mbox: Fixed accessing Dovecot v1.x mbox index files without errors.
