[Dovecot] squat assertion result core dump with imap process
by Kui Zhang 05 Nov '13

Hello, Recently, we had a file system problem. After fsck we started to get some core dump with imap process.

[Dovecot] Message parser loops on certain messages (e.g. with a trailing CR character)
by Tomasz Potega 05 Nov '13

05 Nov '13

Hi, dovecot's message parser enters an endless loop when fed with certain multipart messages with stray CR characters. parse_next_body_to_boundary() assumes the '\r' might be the beginning of a boundary line, reducing the block size by one: src/lib-mail/message-parser.c: 404 /* no linefeeds in this block. we can just skip it. */ 405 ret = 0; 406 if (block_r->data[block_r->size-1] == '\r') { 407 /* this may be the beginning of the \r\n--boundary */ 408 block_r->size--; 409 } For a block size of 1 (e.g. the trailing '\r' character), dovecot ends up processing zero-sized blocks, calling message_parser_read_more() without skipping the input stream: ... #6 0x00007f94f49374c7 in i_stream_read (stream=0xbe2fc8) at istream.c:167 #7 0x00007f94f49383d5 in i_stream_read_data (stream=0xbe2fc8, data_r=0x7fff2141d6b0, size_r=0x7fff2141d6b8, threshold=1) at istream.c:497 #8 0x00007f94f4918c2b in message_parser_read_more (ctx=0xbe7c10, block_r=0x7fff2141d6a0, full_r=0x7fff2141d667) at message-parser.c:128 #9 0x00007f94f491af67 in message_parser_parse_next_block (ctx=0xbe7c10, block_r=0x7fff2141d6a0) at message-parser.c:1012 #10 0x00007f94f491b2fb in message_parser_parse_body (ctx=0xbe7c10, hdr_callback=0x7f94f4c69a75 <parse_bodystructure_part_header>, context=0xbf0450) at message-parser.c:1075 #11 0x00007f94f4c6a876 in index_mail_parse_body (mail=0xbecd00, field=MAIL_CACHE_IMAP_BODYSTRUCTURE) at index-mail.c:895 #12 0x00007f94f4c6aedb in index_mail_parse_bodystructure (mail=0xbecd00, field=MAIL_CACHE_IMAP_BODYSTRUCTURE) at index-mail.c:1046 #13 0x00007f94f4c6b4a5 in index_mail_get_special (_mail=0xbecd00, field=MAIL_FETCH_IMAP_BODYSTRUCTURE, value_r=0x7fff2141d958) at index-mail.c:1170 #14 0x00007f94f4bfab53 in maildir_mail_get_special (_mail=0xbecd00, field=MAIL_FETCH_IMAP_BODYSTRUCTURE, value_r=0x7fff2141d958) at maildir-mail.c:570 #15 0x00007f94f4c36ea1 in mail_get_special (mail=0xbecd00, field=MAIL_FETCH_IMAP_BODYSTRUCTURE, value_r=0x7fff2141d958) at mail.c:269 #16 0x000000000041c5d7 in fetch_bodystructure (ctx=0xbd6a48, mail=0xbecd00, context=0x0) at imap-fetch.c:678 ... You will find a sample message attached to this mail. I have added a check to see if the parser is past the EOF (and omit reducing the block size then) as a band-aid fix, but this might call for a more elegant solution.

[Dovecot] Config problem: want SSL + local roundcube
by Rich 05 Nov '13

05 Nov '13

Hi, Have used dovecot for many years, happy that it worked well without me needing to do anything much! But since the upgrade from v1 to v2.1.7-7 I've come across some config probs. I want IMAP and to force TLS for all internet connections. However, I run RoundCube on the same server (over https) and this needs access too, but this doesn't need to be TLS because it's local anyway. The auto-config update script made some changes, it added the following to force SSL. service imap-login { inet_listener imap { port = 0 } } ssl = required But this seems to forbid the local roundcube service from logging in. Can anyone help me with my config? I had a stab, adding the following, but it didn't work. Was a complete guess anyway! remote 127.0.0.1 { ssl = no service imap-login { inet_listener imap { port = 143 } } } Here's my full config: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 7.2 ext3 auth_default_realm = artfulrobot.com log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/virtual/%d/%n mail_privileged_group = mail passdb { args = username_format=%n /etc/exim4/virtual_domains/%d/passwords driver = passwd-file } protocols = imap service auth { unix_listener auth-client { group = Debian-exim mode = 0660 } user = root } service imap-login { inet_listener imap { port = 0 } } ssl = required ssl_cert = </etc/ssl/certs/mail.artfulrobot.com-with-chain.crt ssl_key = </etc/ssl/private/mail.artfulrobot.com.key userdb { args = uid=1001 gid=1001 driver = static } userdb { driver = passwd } Thanks, Rich

[Dovecot] [bug] ssl-params hangs when FIPS is enabled
by Michal Hlavinka 05 Nov '13

05 Nov '13

Hi, we found a bug in ssl-params. It calls openssl DH generator for 512 and 1024 bits, but in FIPS mode, openssl won't generate anything for less than 1024, so it fails with: error:0506A06E:Diffie-Hellman routines:DH_BUILTIN_GENPARAMS:key size too small but when DH generator fails, ssl-params hangs forever in io_loop_run: __epoll_wait_nocancel() io_loop_handler_run(..) at ioloop-epoll.c:176 io_loop_run(..) at ioloop.c:406 master_service_run(..) at master-service.c:566 main(..) at main.c:156 Getting system in FIPS mode can be a little tricky, but DH_generator simulated failure can do the trick. Just change ssl-params/ssl-params-openssl.c:generate_dh_paramaters:39 - if (dh == NULL) { + if (1 || dh == NULL) { and when you run ssl-params (with no ssl-parameters.dat), it hangs. Let me know if you need more information. Regards, Michal Hlavinka

[Dovecot] Issue with postfix not handing over e-mails to dovecot
by Tru Pheenix 05 Nov '13

05 Nov '13

Hello! I have installed postfix with dovecot and postgresql. I have set up SASL authentication for postfix and dovecot and been able to test them successfully. I am able to send sasl authenticated emails through smtpd on postfix using a mail client like Thunderbird. However, now I am unable to receive any e-mails. When I respond to the emails, I get a not delivered failure from postfix. I cannot figure out why postfix is not handing over the e-mails to dovecot. So here are some links to follow: posftconf output: https://gist.github.com/anonymous/7318863 doveconf output: https://gist.github.com/anonymous/7318896 tail -f /var/log/mail.* output (when receiving mail): https://gist.github.com/anonymous/7318945 Any help to solve this would be highly appreciated.

This is a great idea. In my case I think I will get away with a five minute cron job since the pickup latency should be manageable to the users and there is less to install. But I like in principle the idea of an immediate, fs-driven trigger, which would probably use fewer CPU cycles in the aggregate. > [...]all my users moved messages into spam/yes, > but copied them into spam/no Unfortunately I can't rely on users getting this right, much less understanding the difference between copy and move semantics. And I'm probably not going to be able to upgrade my users. Thanks for your advice! -d

[Dovecot] Is it safe to manipulate Maildir files directly?
by David Henkel-Wallace 05 Nov '13

05 Nov '13

Dovecoters, is it safe to manipulate files in Maildir/xxx directly or will Dovecot become unstable if I don't make these changes by talking to Dovecot and having it make the changes? (I'm running 2.1.7 under Wheezy, IMAP only) My specific application: I am running spamassassin and would like users to be able to submit spam (and ham) directly by moving it into special folders. A cron job can then find it and take action: feed spam messages to the bayesian trainer and then delete them; feed ham messages to the trainer and then move them into ~/Maildir/cur/ Having the cron job find the messages and train spamassassin is no problem. The question is how to move the messages. Is it safe to simply rename the files from my cron job? The dovecot wiki implies that dovecot will notice a change in mtime and deal with it safely. Am I reading this correctly? Changing a message flags (i.e. name) and/or directory will change mtime. If I have to go through to Dovecot I am afraid I'd need the user's credentials, which is not appropriate. Thanks! -d

[Dovecot] backup maildir mailbox bugs

[Dovecot] v2.2.7 released
by Timo Sirainen 04 Nov '13

04 Nov '13

http://dovecot.org/releases/2.2/dovecot-2.2.7.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.7.tar.gz.sig * Some usage of passdb checkpassword could have been exploitable by local users. You may need to modify your setup to keep it working. See http://wiki2.dovecot.org/AuthDatabase/CheckPassword#Security + auth: Added ability to truncate values logged by auth_verbose_passwords (see 10-logging.conf comment) + mdbox: Added "mdbox_deleted" storage, which can be used to access messages with refcount=0. For example: doveadm import mdbox_deleted:~/mdbox "" mailbox inbox subject oops + ssl-params: Added ssl_dh_parameters_length setting. - master process was doing a hostname.domain lookup for each created process, which may have caused a lot of unnecessary DNS lookups. - dsync: Syncing over 100 messages at once caused problems in some situations, causing messages to get new UIDs. - fts-solr: Different Solr hosts for different users didn't work.

[Dovecot] Shared mailbox help needed
by Alex Ferrara 04 Nov '13

04 Nov '13

Hi everyone, I am in the middle of a migration from Cyrus 2.4 to Dovecot 2.1.7, and I have everything mostly working. I set up Dovecot to authenticate against Active Directory (Samba4) using PAM and SSSD, and have also used the fantastic cyrus2dovecot perl script to do a test migration of all our mail, and that is now working flawlessly. I have the issue of shared IMAP accounts to deal with, and I am a little stuck. I see that Dovecot is very flexible, and I think I am getting stuck in this flexibility. I thought that if I explain what I am trying to achieve, someone might point me in the right direction. In the Cyrus regime, we have several imap accounts that are shared with a group of people. These groups are actual unix groups that actual unix users are a member of. If we want a person to access a mailbox, we add them to the group and then at next login, it pops up in Thunderbird automatically. SSSD does, from what I can tell, a decent job of binding to AD and mapping AD users to unix users, but since not all of the users have an NIS uid in AD, I decided to use a static mapping. This might have been the wrong decision, I am not sure. userdb { driver = static args = uid=900 gid=900 home=/mnt/mail/%u allow_all_users=yes } It probably isn't important at this stage, but the mail spool is stored on an NFS server and the indexes are stored locally. Thanks in advance, Alex Ferrara Director Receptive IT Solutions

Re: [Dovecot] Doveadm with a 2nd Instance
by Chris Lasater 03 Nov '13

While testing some more I found out something else. I have an alias set for doveadm so it was running with sudo and that ended up being part of the issue. If doveadm is run as a regular user then the problem goes away [user@server ~]$ doveadm -i Director log find Debug: /home/user/apps/logs/director/director_debug.log Info: /home/user/apps/logs/director/director_info.log Warning: /home/user/apps/logs/director/director.log Error: /home/user/apps/logs/director/director.log Fatal: /home/user/apps/logs/director/director.log [user@server ~]$ sudo doveadm -i Director log find Debug: /home/user/apps/logs/dovecot_debug.log Info: /home/user/apps/logs/dovecot_info.log Warning: /home/user/apps/logs/dovecot.log Error: /home/user/apps/logs/dovecot.log Fatal: /home/user/apps/logs/dovecot.log Also if I run "sudo doveadm stop" to stop the main instance, I now have the ability to use the -i Director using sudo. Unfortunately this makes it difficult to manage two instances. Does anyone have an idea of getting this to work with sudo? Chris

[Dovecot] Encryption solution for messages at rest
by Douglas Mortensen 03 Nov '13

03 Nov '13

Hi, We have clients with various security & compliance requirements. Although not required, it would be ideal to have messages encrypted at rest. We already use SSL/TLS to secure the transmission of most email. However, it would be nice to have them encrypted sitting on our server. Is anyone doing this? I think that ideally, rather than full-disk encryption, we should use an encryption that encrypts the actual email messages as they sit on our file system. This way even if we ever had our server breached by an attacker, they wouldn't be able to do anything with the messages. However, this would also mean that if the attacker can't decrypt the files, than dovecot and postfix still would need to. This means that the encryption key would need to be available to the dovecot deamon. We'd either need to have it in a file that is restricted to access only by dovecot (less secure), or use an encryption passphrase for the certificate which would have to be typed in manually each time that dovecot starts or restarts (more secure, but also more work and possibility of disruption because the server can't restart gracefully without a human being having to be present [although I don't think we have issues with unexpected restarts anyway]). Is anyone doing anything like this with dovecot? Thanks!! - Doug Mortensen Network Consultant Impala Networks Inc CCNA, MCSA, Security+, A+ Linux+, Network+, Server+ A.A.S.

[Dovecot] Assertion error in Dovecot 2.2.6
by Mark Sapiro 03 Nov '13

03 Nov '13

Background. A while back I upgraded my phone to one currently using Android 4.1.2 and K9 mail 4.409. This phone/MUA combination seems at times to go crazy making IMAP connections. At first, I had mail_max_userip_connections = 30 (my largest imap account has 19 folders). The issue I had at that time was multiple errors like Oct 14 17:45:16 sbh16 dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=30): user=<xxx>, method=PLAIN, rip=xx.xx.xx.xx, lip=xx.xx.xx.xx, TLS, session=<c63x5bzowQBi0uQR> I then set mail_max_userip_connections = 50 This greatly reduced but didn't completely eliminate these messages, but then I would see multiple Oct 31 16:13:40 sbh16 dovecot: master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped and Oct 31 16:13:40 sbh16 dovecot: imap-login: Disconnected: Connection queue full (no auth attempts in 4 secs): user=<>, rip=xx.xx.xx.xx, lip=xx.xx.xx.xx, TLS handshaking, session=<s26xmRHqVQBi0uQR> followed finally by Oct 31 16:13:40 sbh16 dovecot: imap-login: Panic: file client-common.c: line 190 (client_destroy): assertion failed: (!client->authenticating) Oct 31 16:13:40 sbh16 dovecot: auth: Warning: auth client 19669 disconnected with 1 pending requests: EOF Oct 31 16:13:40 sbh16 dovecot: imap-login: Fatal: master: service(imap-login): child 19669 killed with signal 6 (core not dumped - add -D parameter to service imap-login { executable } I then set default_process_limit = 200, and things seem to have settled down, but I thought the panic should be reported.

[Dovecot] METADATA for v2.2.7
by Timo Sirainen 02 Nov '13

02 Nov '13

In case someone wants to try: http://hg.dovecot.org/dovecot-2.2/rev/0a08efeb3f40 The commit message lists the TODO. So for example if you want to enable it just for webmail (because quota limits aren’t there yet): mail_attribute_dict = file:%h/dovecot-attributes local 10.0.0.0/24 { imap_metadata = yes } Compared to the old metadata plugin, there are some improvements: - Uses lib-storage attributes internally, which means: - dsync replicates METADATA - it will be easy to add support for untagged METADATA notifications to clients when they change - SETMETADATA atomically either updates all or none of the changes Things that work in the METADATA code, but still require lib-dict changes to work properly: - Values with unlimited sizes - Values with binary data (NULs)

[Dovecot] DH parameter length too small?
by Jörg Lübbert 02 Nov '13

02 Nov '13

Hello, from my understanding, using 1024bit DH parameters results in a not sufficiently secure key exchange for DH(E). Therefore I think it would be advisable to have parameters of at least 2048bit . In fact, I would see a great benefit in chosing parameter length arbitrarily. I also do not see the benefit of parameter regeneration. What were the design goals here? Thanks, Jörg Lübbert

[Dovecot] Shared namespace, separator, username and dots.
by Marcio Merlone 02 Nov '13

02 Nov '13

Hi folks, I run a legacy mailserver that i had replaced courier-imap for dovecot 1.2. Everything is fine except for shared namespace. Maildir structure has been created using dot '.' as folder separator. It happens that all our users are created as name.surname as default. So when I want to select a shared folder, MUA end up with the following IMAP command: select shared.jhon.doe.folder.subfolder Obviously I took ages to figure why it won't work since it takes 'doe' as a folder and not a username part. When sharing a folder from 'sales' user, for example, it works fine. What do you suggest to make shared folders work for all without rebuilding hundreds of maildirs to change folder separator from '.' to '/'?

02 Nov '13

We're running Dovecot 2.1.17 on Debian: # 2.1.17 (9efbc0731929): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab078.27.debug i686 Debian 7.1 simfs and we're having this namespace configuration: mail_location = mdbox:/var/mail/%Ld/%Ln/mdbox namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = prefix = separator = . subscriptions = yes type = private } As you can see, our namespace seperator is "." and not "/": a LIST "" "*" * LIST (\HasChildren) "." INBOX.test * LIST (\HasNoChildren) "." INBOX.test.huhu * LIST (\HasNoChildren \Trash) "." Trash * LIST (\HasChildren) "." INBOX a OK List completed. The problem is, that doveadm isn't able to import his own mdbox-directory: 1) delete the whole mdbox folder # rm -rf mdbox 2) create the new mdbox folder and create some subfolders in it # doveadm mailbox create -u max.muster INBOX.test # doveadm mailbox create -u max.muster INBOX.test.huhu 3) put a mail into a subfolder 4) try to re-import the whole mdbox: it doesn't work # doveadm import -u max.muster mdbox:mdbox BACKUP all doveadm(max.muster): Error: Couldn't create mailbox BACKUP.INBOX/test/huhu: Character not allowed in mailbox name: '/' Looks like there's something wrong in the namespace or like doveadm is working with a hardcoded internal namespace...

[Dovecot] Configuring SPECIAL-USE Dovecot 2.0.9
by Keith Mountifield 01 Nov '13

01 Nov '13

Hi All, I'm trying to configure Dovecot 2.0.9 to support Outlook 2013. As I understand it, I need to configure XLIST. I have added imap_capability = +XLIST to 20-imap.conf When I try to query the IMAP folders I get an error "An IMAP command Failed". Looking at the logs I get XLIST Command not found. I can only assume that I'm missing something in the configuration. Any help would be greatly appreciated Thanks Keith

[Dovecot] init script as provided http://wiki2.dovecot.org/DovecotInit
by Jess Portnoy 01 Nov '13

01 Nov '13

Hello list, I would add: # dovecot Startup script for the dovecot server # # chkconfig: - # processname: dovecot # config: /path/to/config # pidfile: /path/to/pid So that it supports the chkconfig used by RHEL and clones too. Also, maybe it should be installed by the Makefile's install target? it could then also set: DAEMON=/path/to/dovecot/daemon instead of: DAEMON=/usr/local/sbin/dovecot Cause naturally, it will know the prefix chosen. May the source be with you, Jess Portnoy

[Dovecot] Logging in to a virtual users Maildir
by Steve Downes 01 Nov '13

01 Nov '13

Trying to set up a mailserver to run exim4, dovecot2, (clamav procmail or similar not yet installed) on a virtual machine & access it from various hosts mostly using Mutt. So far no attempt at encryption although there are some pem files from a previous attempt & some evidence from the mutt debug file they may be being used . So far I have attempted to set up dovecot to by accessed by MUAs only & tried to access it from Mutt on on the mailserver virtual machine & on another on locally networked machine (no networking problems). When I open a local mutt I get the following:- 1) could not connect to vmail-s (connection refused) (vmail-s is the mailserver host) 2) mutt then opens, with a blank message screen 3) from mutt I then put C (open mailbox ? for list) & ?. 4) I then get a file list for the mailbox including all dovecot files but no mailbox files except cur. new, & tmp 5) if enter on ../ I get (presumably) /home/vmail/users/steve/ showing Maildir as the 2nd line 6) select Maildir gives me my inbox but continuing the process does not give me acces to any other folders. The files in my mailbox are from my previous version of Dovecot (V1*) but I have previously tried to start anew set of mailboxes with similar results. I enclose below:- my Dovecot.conf file My muttrc file a .muttdebug0 file Dovecot log files show nothing but Dovecot stop/start lines. Any pointers please?

[Dovecot] IMAP Dovecot unknown namespace creating root folders
by marcus lively 31 Oct '13

31 Oct '13

Hi, I hope someone can point me in the right direction here. I am migrating a mailbox from a non cPanel server, and the mailboxes have folders which seem to be at the same level as the Inbox. The users access these mailboxes using IMAP. The new server configuration is Exim > Dovecot 1.2.17 > Maildir with the standard cPanel install settings. dovecot -n output below I have created the new mailbox within cPanel however when I try to create a 'top level' folder in Outlook I receive the error 'Cannot create the folder: Unknown namespace' (Note I also tried this with the windows mail client to ensure it was not client side) I know that I can get round this by setting the root folder path on the client to 'Inbox' and therefore the folders would be created as sub-folders of Inbox, and this would not be visible to the user, but I was hoping to migrate without touching the clients. Should dovecot report the default root folder path automatically, or create a default top level namespace for each user so this can be done, or could I have just gone wrong and missed something. Any advice on getting this working appreciated, thanks for any help Maspry # 1.2.17: /etc/dovecot.conf # OS: Linux 2.6.32-71.el6.x86_64 x86_64 CentOS release 6.4 (Final) protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/dovecot/ssl/dovecot.crt ssl_key_file: /etc/dovecot/ssl/dovecot.key ssl_cipher_list: ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_process_per_connection: no login_processes_count: 2 login_max_processes_count: 50 login_max_connections: 500 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 3 maildir_copy_preserve_filename: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): acl quota imap_quota mail_plugins(imap): acl quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v pop3_logout_format(default): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(imap): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(pop3): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s, bytes=%i/%o namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login cache_size: 1024 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!#$-=?^_{}~./@+% passdb: driver: checkpassword args: /usr/local/cpanel/bin/dovecot-auth userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir quota_rule: Trash:ignore acl: vfile

Re: [Dovecot] Encryption solution for messages at rest
by Douglas Mortensen 30 Oct '13

30 Oct '13

Currently our dovecot servers are on our webhosting linux boxes. We are using the LAMP stack to host websites, and also doing email with postfix & dovecot on these systems. We provide this as a hosting setup for 100+ accounts/websites on a single server (a multi-tenant setup). Each customer has anywhere between 1-100 email accounts which Dovecot services. If a customer has vulnerable PHP code on a website, some of these will allow a remote file upload. I have seen cases where they upload a PHP script that is a sort of web-based console/shell to the server (file-system, etc.). It provides several tools which all run through the uploaded PHP script to try to brute force and do other attacks. I've seen attempts at a root exploit. We've never had a root exploit and any such case of a customer's site being hacked has been easily contained by simple filesystem permissions being correct (and the fact that we have apache setup to run all scripts as the user who is the owner of the script files, which confines the script to that users' permissions). Still nobody loves the idea of bad guys trying to hack on your box. So.... given that type of scenario, if filesystem permissions weren't correct, or some new exploit surfaced that allowed someone bypass or elevate to root, then they could theoretically have access to the entire fileystem including where emails are stored. I hope to never have this sort of thing happen. We patch our systems regularly and have other security measures we follow to prevent this. We also are managing most of the PHP scripts customers use ourselves now and are updating those for the CMS' and other systems proactively. However, it would be nice to know that even if we were breached, the emails on the server were encrypted and would be completely useless to an attacker. This type of encryption is ideal and some regulations prefer (although don't require) it. - Doug Mortensen Network Consultant Impala Networks P: 505.327.7300 -----Original Message----- From: dovecot-bounces(a)dovecot.org [mailto:dovecot-bounces@dovecot.org] On Behalf Of Michael Orlitzky Sent: Monday, October 28, 2013 11:52 AM To: dovecot Subject: Re: [Dovecot] Encryption solution for messages at rest On 10/28/2013 12:02 PM, Douglas Mortensen wrote: > Hi, > > We have clients with various security & compliance requirements. > Although not required, it would be ideal to have messages encrypted at > rest.

[Dovecot] Right values for Antispam plugin
by Michael Neurohr 30 Oct '13

30 Oct '13

Hi! I'm currently configuring the Dovecot Antispam plugin for the use with Dspam. In general it works, but I'm not sure about one special config parameter: antispam_dspam_args At the moment I set it to: antispam_dspam_args = --source=error;--signature=%%s;--user;%u Is that the appropriate value for retraining? I'm not sure if "%%s" is correct to get the signature value. I was not able to find any documentation that describes that value. So I just want to know if my plugin config is correct for retraining. plugin { antispam_backend = dspam antispam_spam = Spam antispam_trash = trash;Trash;Deleted Items;Deleted Messages antispam_signature = X-DSPAM-Signature antispam_signature_missing = move antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --source=error;--signature=%%s;--user;%u } Thanks, Michael

Webservers are best treated as "disposable" and should be heavily sandboxed. Any resources they can use should be vetted and ideally set as "read only" Inbound external access should be firewalled down to the webserver ports and OUTBOUND traffic should be firewalled too (If it has no business initiating external connections then block all SYNs), in order to stop it becoming a DDoS zombie. It's foolish (at best) to have mail servers running on a webserver, because if it's compromised it can immediately be used as a spam engine without much further effort. At least if it has to hand mail off to another mailserver you have a chance to run outbound filtering on the emitted mail without worrying about that being compromised too.

Hi to all. Is it possible to disable unsecure POP3 protocol at all in Dovecot 2.1? There was "protocols" option in 1.x version, and there was separate pop3 and pop3s modules. There is no "pop3s" in configuration files in 2.1.

[Dovecot] Problem with dovecot-lda
by Wolfgang Ganzert 29 Oct '13

29 Oct '13

Hello Ladies and Gentlemen, first of all I have to say that dovecot is really impressive. I seems to be a very goot IMAP server and has in general a good documentation. I'm a beginner regarding the administration so please excuse if my questions sound silly but I want to learn to administrate these sophisticated things. Now here's my configuration: Linux openSuSE 12.1 Postfix 2.8.8 Dovecot 2.0.16 Boundary condition: Postfix as smtp (Postfix is configured as relay server; mail is sent to smtp.web.de if mail is not locally distributed) Dovecot as IMAP server in my private network (192.168....) Situation: I want to store outgoing mail which is send by postfix also in a "SENT" folder in Dovecot. The SENT folder is available and created through the plugin "autocreate". The main.cf file from postfix contains the following mailbox command: mailbox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" -m SENT If I send a simple mail from the shell with the following command echo "Hello me" | mail -s "Dovecot test 50, shell nach SENT" $USER the mail is send to my mailbox and stored in the folder "SENT" as unread. Problem: 1. I would expect to have to mails coming in; one in my "SENT" folder because this is copy of the mail and another one which is the incoming folder because the mail was sent to me. But, there is no mail in the incoming folder. 2. If I use a mail client like kmail2 the same thing happens. The mail is distributed to the SENT folder but there's no copy in the incoming folder. 3. If I send a mail to my adress at @web.de with the postfix configuration from above I do not receive the mail at web.de. 4. If I send a mail to my adress at @web.de with a postfix simplified mailbox command NOT containing the mailbox with "-m", then mail is send to web.de and there I receive it in the incoming box. This is the simplified command: mailbox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" Summary: All examples from above show that I do not get a COPY of the outgoing mail in my "SENT" folder but it's the REAL mail. Can You please give me some advice what to do? Thank You! Wolfgang P.S.: In /var/log/mail and /var/log/dovecot.log I do not get any errors.

[Dovecot] Building the Antispam plugin fails
by Michael Neurohr 29 Oct '13

29 Oct '13

Hi! I'm running Dovecot 2.2.5 on a CentOS 6.4 server from the ATRPMs repository. Unfortunately this repo does not provide a packaged version of the Antispam Plugin. So I followed the steps outlined in the Dovecot Wiki [1]. But when running the command ./configure, I get stuck with the following error: checking for dovecot-config in "/usr/local/lib/dovecot"... not found configure: configure: Use --with-dovecot=DIR to provide the path to the dovecot-config file. configure: error: dovecot-config not found So I downloaded the dovecot-devel package and run the configure command again with the following command: ./configure --with-dovecot=/usr/include/dovecot but with the same result. I made sure the the directory "/usr/include/dovecot" does contain the Dovecot header files. What can I do next? Do I really also have to install Dovecot from the sources only to get the Antispam Plugin working? Thanks, Michael [1] http://wiki2.dovecot.org/Plugins/Antispam

[Dovecot] Encryption solution for messages at rest

Webservers are best treated as "disposable" and should be heavily sandboxed. Any resources they can use should be vetted and ideally set as "read only" Inbound external access should be firewalled down to the webserver ports and OUTBOUND traffic should be firewalled too (If it has no business initiating external connections then block all SYNs), in order to stop it becoming a DDoS zombie. It's foolish (at best) to have mail servers running on a webserver, because if it's compromised it can immediately be used as a spam engine without much further effort. At least if it has to hand mail off to another mailserver you have a chance to run outbound filtering on the emitted mail without worrying about that being compromised too.

[Dovecot] recipient_delimiter deux
by LuKreme 29 Oct '13

29 Oct '13

OK, I've been banging my head on why my procmail setup for virtual users is no longer working (difficult to test, since enabling it breaks live user's mail). There are only a few virtual users who have any sort of filters in place anyway (the heavy procmail users are local, not virtual), and they are fairly simple, so I think I can recreate them with sieve. I think I have everything I need for sieve to work, but now what? The first thing I want to do is have sieve process recipient_delimiter into a separate mailbox (creating it, if needed). Googling just for example sieve scripts comes up empty (well, directing to the dovecot wiki which at least on the links that come up, does not have sample scripts). so, foo+bar(a)example.com will go into foo's mailstore in the folder .bar/new/ On 27 Sep 2013, at 00:24 , Steffen Kaiser <skdovecot(a)smail.inf.fh-brs.de> wrote: > Dovecot LDA uses the "-m" option and only lda_mailbox_autocreate and lda_mailbox_autosubscribe, no need for recipient_delimiter to override the default mailbox. Which I still don't understand. recipient_delimiter = + is the default, so I shouldn't need to set it in my confs, I just need to setup a sieve recipe (is that what it is called? script?) that will process these messages, right? What would that look like? I have to setup the SQL users so that LMTP or LDA is used for deliver, but I want that to apply only to the sql users. Something like this, maybe? userdb { args = /etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u mail=maildir:/usr/local/virtual/%u sieve=/var/sieve/%u.sieve protocol_lda=$mailplugins sieve driver = sql } I'm sure that protoco_lda isn't the right syntax though. If I set sieve=/var/sieve/%u.sieve as above would users still be able to use sieve-manage to manage their own sieve files? And what MUAs support this? If I left that out, do I put ~/.dovecot.sieve in with the other mailboxes and {cur,new,tmp} and the index files, or will there be issues? If I put a dovecot.sieve file there will it just be seen, processed, and work?

[Dovecot] pigeonhole sources no more available
by me＠electronico.nc 29 Oct '13

29 Oct '13

Hi all, Please excuse me for this message but I can't find the pigeonhole sources available anymore. This page : http://pigeonhole.dovecot.org/download.html Points to (for latest sources) : http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.2.tar.gz And it seems that : www.rename-it.nl is now : http://www.medicalbits.nl So we get 404 error ... Could someone point us the to right URL and, maybe, update pigeonhole.dovecot.org ? Thanks in advance for your time. Nicolas

[Dovecot] Dovecot replication - I'm stuck
by IT geek 31 28 Oct '13

28 Oct '13

Hi, I've been following the wiki document at http://wiki2.dovecot.org/Replication, but I've become stuck. I'm running version 2.1.3 on NetBSD 5.2 (v2.2+ isn't available as a package yet, and compiling my own is well outside my wheelhouse). I have a couple of questions: The wiki page keeps referring to "vmail". Is this a just system user I need to create? Presumably on both Dovecot boxes? If I don't use virtual users, do I need this? Here is my dovecot -n: # 2.1.3: /usr/pkg/etc/dovecot/dovecot.conf # OS: NetBSD 5.2 cobalt auth_mechanisms = plain login dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u listen = 192.168.1.1 login_greeting = Go on then, let's have it... mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_plugins = " notify replication" passdb { driver = passwd } plugin { mail_replica = remote:vmail@server2.mydomain.com replication_full_sync_interval = 1 hours } protocols = imap service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { inet_listener imap { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/openssl/certs/mail.mydomain.com.crt ssl_key = </etc/openssl/private/mail.mydomain.com.key userdb { driver = passwd } protocol lda { postmaster_address = postmaster(a)mydomain.com } Any help would be greatly appreciated, as I'd really love to get this working.

Just in case someone else has the same problem, I had to change the following two variables mail_home = /mnt/home/imapd/%d/%n mail_location = dbox:/mnt/home/imapd/%d/%n to mail_home = /mnt/home/imapd/%d/%n mail_location = dbox:~/ "When mail_location begins with%h or~/, its permissions are copied from the first existing parent directory if it has setgid-bit set. This isn't done when the path contains any other %variables."

[Dovecot] Blocking certain hostnames/clients
by Charles Marcus 28 Oct '13

28 Oct '13

Hello, As a result of learning of the new 'Intro' App introduced by LinkedIn, and discussing how to block SMTP access to my postfix server from these clients, I'm now interested in doing the same for dovecot. Bottom line desire is to avoid scraping/hijacking email stored on my dovecot server by any client other than a users client. This includes Intro (so, LinkedIn), Blackberry, GMail, Outlook, etc. The boss has expressed the desire to NOT block all email from them, just disallow any of their clients from AUTH'ing (either SMTP or IMAP/POP). I'd be interested if anyone has any kind of database of hostnames/IP blocks of the freemailers out there that support adding 3rd party accounts, especially ones supporting IMAP. Anyway, article raising the concern found here: http://www.bishopfox.com/blog/2013/10/linkedin-intro/ "LinkedIn released a new product today called Intro. They call it ?doing the impossible?, but some might call it ?hijacking email?. Why do we say this? Consider the following: Intro reconfigures your iOS device (e.g. iPhone, iPad) so that all of your emails go through LinkedIn?s servers. You read that right. Once you install the Intro app, all of your emails, both sent and received, are transmitted via LinkedIn?s servers. LinkedIn is forcing all your IMAP and SMTP data through their own servers and then analyzing and scraping your emails for data pertaining to?whatever they feel like." -- Best regards, */Charles/*

[Dovecot] Which MTA for a personal-use dovecot instance?
by Dan Langille 27 Oct '13

27 Oct '13

I'm planning to deploy a personal dovecot IMAP server (i.e. I am the only user) in a FreeBSD jail. At present, I have IMAP deployed on the same host as one of my mail servers, which is running Postfix. I do like Postfix, but it seems to be a bit overkill for this particular situation. All my incoming MX are provided by Google. They handle the incoming mail and forward to my private MX, and from there the mail for me goes into my ~/Maildir. With the move to IMAP in a jail, I need to get the mail from my private MX into that jail. All mail being sent to that jail will be destined for my ~/Maildir, with some massaging via procmail. Given that I've just started using mail/nullmailer, I was wondering if there was something simple that I could use. I was planning to use postfix, require TLS, lock things down tightly. But I'm open to suggestions for something simple. -- Dan Langille - http://langille.org/

[Dovecot] Dovecot proxy hooks
by dac＠getodata.ro 26 Oct '13

26 Oct '13

I am interested in the possibility of using Dovecot IMAP/POP proxying capabilities to analyze emails that are passing through and possibly modify content on the fly. This subject has been discussed here [1] before. I have tried the mail-filter plugin [2], but the hooks it uses are only called in a non-proxy setup. Is there a practical way of doing this, or plans to add such a feature?
