[Dovecot] Autocreation of sieve filters
by Angel L. Mateo 14 Nov '13

14 Nov '13

Hello, Is there any way to create a predefined sieve filters during mailbox autocreation? What I want is that my user's mailboxes are automatically created (using mailbox option in namespaces) but I want them to have a predefined sieve script. Using a postlogin script could be an idea, but I'd prefer an automatic one, because postlogin only will filter after first user login -- Angel L.

[Dovecot] Dovecot 2.0.9 Quota Limit issues
by David Johnson 13 Nov '13

13 Nov '13

Hello, I've tried searching for information regarding this problem but haven't found anything. Currently I have a Dovecot 2.0.9 with virtual users from a SQL table. Right now I'm only using global quota limits. Here is my quota setup: plugin { quota = maildir:User quota quota_rule = *:storage=3G quota_rule2 = Trash:storage=+100M quota_rule3 = Archive:storage=+1G quota_rule4 = Archive/2013:storage=+1G quota_rule5 = Junk:ignore } According to the documentation this should allow the Archive folder to have an additional 1G in it that is not counted toward the global 3G. However I have users who have 2G in the Archive folder, and about 1G elsewhere. At this point they stop receiving emails due to quota exceeded. doveadm quota get -u <user> displays this: Quota name Type Value Limit % User quota STORAGE 3150312 3145728 100 User quota MESSAGE 8271 - 0 If I change Archive:storage=+1G to Archive:ignore then they can receive emails again. After the change doveadm quota get -u displays this: Quota name Type Value Limit % User quota STORAGE 1266885 3145728 40 User quota MESSAGE 8271 - 0 Is there something I'm missing as to why this setup isn't working? Thanks! -- David J.

[Dovecot] Can't see e-mails
by Muzaffer Tolga Ozses 12 Nov '13

12 Nov '13

Hi, I have a postfix+dovecot+mysql+roundcube setup. I recently changed providers. At the moment, postfix can receive e-mails but either dovecot or roundcube can't see e-mails. I did a telnet example.com 143 then a login user pass and this is what I see: 2013-11-12 16:08:51 auth: Debug: sql(alanya(a)boradental.com.tr,193.255.135.254): SELE CT '/var/vmail/boradental.com.tr/alanya' as home, 'maildir:/var/vmail/ boradental.com .tr/alanya' as mail, 5000 AS uid, 5000 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = 'alanya(a)boradental.com.tr' AND active = '1' 2013-11-12 16:08:51 auth: Debug: master out: USER 3767009281 alanya@borad ental.com.tr home=/var/vmail/boradental.com.tr/alanya mail=maildir:/va r/vmail/boradental.com.tr/alanya uid=5000 gid=5000 quota=dirsize:storage=0 so I'm assuming dovecot works. Am I right to assume this? If I'm not, what's the solution? If I am, how can I debug this? Regards,

[Dovecot] Dovecot MTA
by Timo Sirainen 12 Nov '13

12 Nov '13

Hi all, I've never really wanted to create my own MTA, because I like Postfix quite a lot. And I always thought it would require a horribly lot of time to be able to create something that was anywhere even close to having Postfix's features. (I would shudder to even think about recreating Dovecot from scratch nowadays.) But slowly over time I've also been thinking of ways how things could be done a bit better, and I think I have enough ideas to start thinking about Dovecot MTA more seriously in a few more months (after my current busy schedule calms down a bit). And (unlike Dovecot!) I'm not planning on taking over the world with the MTA (or at least not very quickly), but it would definitely be useful for many installations I know of. My main design goals for the MTA are: * In normal load don't queue mails, just continue delivering the mail through different processes/services until it succeeds or fails, and only after that return ok/failure to the SMTP client. So there's no (forced) post-queue filtering, everything would normally happen pre-queue. This is required because in Germany (and EU in general?) you aren't allowed to just drop spams after SMTP server has responsed OK to the client, even if you’re 100% sure it’s a spam. So this would also mean that the SMTP DATA replies will come more slowly, which means that the SMTP server must be able to handle a lot more concurrent SMTP connections, which means that in large installations the smtpd process must be able to asynchronously handle multiple SMTP client connections. * In some cases you can't really avoid placing mails into a queue. This could be because of temporary failures or maybe because of an abnormal load spike. A mail queue in local disk isn't very nice though, because if the local disk dies, the queued mails are lost. Dovecot MTA will allow the queue to be in object storage and it will also likely support replication (similar to current dsync replication). In both of these cases if a server dies, another server can quickly take over its queue and continue handling it. * Dovecot MTA is a new product, which means we can add some requirements to how it's being used, especially related to securely sending emails between servers. It could do a bunch of checks at startup and fail to even start if everything isn't correct. Here are some things I had in mind - not sure if all of these are good ideas or not: - Require DKIM configuration. All outgoing mails will be DKIM signed. - Require the domain’s DNS to contain _submission._tcp SRV record (and actually might as well require _imap._tcp too) - Require SSL certificates to be configured and always allow remote to use STARTTLS - Require DANE TLSA record to exist and match the server's configured SSL cert - Have very good (and strict?) DNSSEC support. If we know a remote server is supposed to have valid DNSSEC entries, but doesn't, fail to deliver mail entirely? - Add a new DNS record that advertises this is a Dovecot MTA (or compatible). If such entry is found (especially when correctness is guaranteed by DNSSEC), the email sender can assume that certain features exist and work correctly. If they don't, it could indicate an attack and the mail sending should be retried later. This DNS record would of course be good to try to standardize. * Configuration: It would take years to implement all of the settings that Postfix has, but I think it's not going to be necessary. In fact I think the number of new settings to dovecot.conf that Dovecot MTA requires would be very minimal. Instead nearly all of the configuration could be done using Sieve scripts. We'd need to implement some new MTA-specific Sieve extensions and a few core features/configurations/databases that the scripts can use, but after that there wouldn't be really any limits to what could be done with them. * Try to implement as many existing interfaces as possible (e.g. Milter and various Postfix APIs like policy servers) so that it wouldn’t be necessary to reimplement all the tools and filters. So perhaps something like this could be done in time for Dovecot v2.4. Any thoughts/ideas/suggestions?

This won't protect against: * NSA listening in on the mails when they arrive. * NSA taking a backup of your mails and wait for your first attempt to read them - at which time they'll have your private key in plain text.

[Dovecot] Can't get sieve/managedsieve working

When I try to edit filters with thunderbird sieve plugin 0.2.2 nothing happens. If I try to edit filters with roundcube managesieve plugin nothing happens, too, but I get some errors in logfile: > roundcube: "Authentication failed."

[Dovecot] Dovecot replication not redirecting if server is down

The bug is related to the sieve module in /src/lib-sieve/plugins/notify/ext-notify-common.c:266. The line contains only a check if mail_get_headers_utf8 returns an error. So the workaround for this line would be to add a check if header[0] is not NULL. if ( (mail_get_headers_utf8(msgdata->mail, "subject", &header) >= 0) && header[0] ) str_append(out_msg, header[0]); IMHO this patch should be applied to the "$from$" replacement as well. The comments in the dovecot's header file says for mail_get_headers: Returns -1 if error, 0 otherwise (with or without headers found). hope it helps, Regards Christian Ferbar

[Dovecot] Question about folder sharing
by Achim Gottinger 09 Nov '13

09 Nov '13

Hi, I run dovecot (2.1.7) on debian wheezy in conjuniction with postfix, samba4 (as ldap backend) and sogo. I configured folder sharing but have an few issues. With my current config users can share the inbox and other folders. If the acl allows creatings subfolders this does work for all folders beside inbox. What i want to archiev is the following: If an user shares his inbox, others should be able to create subfolders and those should inherit the inboxe's acl. All subfolders of inbox should appear as folders at root level and not as subfolders of the inbox. I thought this can be done by setting the prefix of namespace inbox to INBOX/. I did this and changed the IMAP Server Folder setting in thunderbird to INBOX (like it was earlier when i used courier). Now subfolders created at rootlevel or as subfolders of the inbox appear on rootlevel in thunderbird but they do not inherit the acl's from inbox. Is there an way to achive this? doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 ext4 auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_master_user_separator = % auth_mechanisms = plain login gssapi auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% auth_username_format = %n auth_verbose = yes debug_log_path = syslog disable_plaintext_auth = no first_valid_gid = 998 first_valid_uid = 998 info_log_path = syslog mail_debug = yes mail_gid = 998 mail_home = /home/vmail/%u mail_location = maildir:/home/vmail/%u/mail mail_plugins = acl mail_shared_explicit_inbox = no mail_uid = 998 maildir_very_dirty_syncs = yes 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 namespace { list = children location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = maildir:/home/vmail/%u/mail prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap-passdb.conf.ext driver = ldap } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } plugin { acl = vfile acl_anyone = allow acl_shared_dict = file:/home/vmail/.shared-mailboxes sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0777 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap-postlogin { executable = script-login /etc/dovecot/acl-groups.sh user = $default_internal_user } service imap { executable = imap imap-postlogin } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/easy-rsa/keys/dovecot.crt ssl_key = </etc/easy-rsa/keys/dovecot.key userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } userdb { args = /etc/dovecot/dovecot-ldap-userdb-groups.conf.ext driver = ldap } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = acl imap_acl } protocol lmtp { mail_plugins = acl sieve }

[Dovecot] how to calculate mail storage/traffic used
by Götz Reinicke - IT Koordinator 08 Nov '13

08 Nov '13

Hi, may be som mailserver admins on the list can give me som hint. Thats not dovecot related, but I know the knowledg here is enormous. We have to setup a server which gets a copy of all messages send and received by our mailserver as a 1:1 copy. Mails send to multiple recipients should be calculated and saved per user. (great if you usually have lost of mails send to groups of people.) So no dedublication should be used here. (e.g. save the message and refer the different recipients to it.) How can I calculate the current traffic in the best way to extrapolate the amount of space to be planed for the new server? We think to have a couples of days to be saved. Thanks for any hint or comment.

[Dovecot] Solr clusters
by Timo Sirainen 07 Nov '13

07 Nov '13

Hi all, Has anyone implemented larger Dovecot+Solr clusters and would be willing to give some details about how it works for you? My understanding about it so far is: - SolrCloud isn’t usable with Dovecot. Replication isn’t useful, because nobody wants to pay for double the disk space for indexes that could be regenerated anyway. The autosharding isn’t very useful also, because: I think the shard keys could be created in two possible ways: a) Mails would be entirely randomly distributed across the cluster. This would make updates efficient, because the writes would be fully distributed across all servers. But I think it would also make reads somewhat inefficient, since all the servers would have to be searched and the results combined. Also if a server is lost, there’s no easy way to reindex back the missing data, because it would contain a piece of pretty much all the users’ data. b) Shard keys could be created so that the same user would typically go only to 1-2 servers. It would be possible (at least in theory) to find a broken server’s list of users and reindex only their data, but I’m not sure if this method is any easier than the non-SolrCloud setup. - Without SolrCloud you’d then need to shard the data manually. This would be easy enough to do by just assigning different users to different shards. But at some point the index is going to become too large and you need to add more shards and move some existing users to them. To keep the search performance good during the move, I guess this could be done with a script that does: 1) reindex user to new shard, 2) update userdb to point to new shard, 3) delete user from old shard, 4) doveadm fts rescan the user to remove any mails already deleted during the reindexing. - It seems that Solr index shouldn’t grow above 200 GB or the performance will be getting too bad? I’ve seen this in a few web pages. So each server should likely be running multiple separate Solr instances (shards). - http://www.hathitrust.org/blogs/large-scale-search/scaling-large-scale-sear… recommends NFS (or I guess any kind of a shared filesystem), which does seem to make sense. Since Dovecot wants to get instantly updated search results after indexing, I think it’s probably better not to separate the indexing and searching servers. - Would be interesting to know what kind of hardware your Solr servers currently have, how well they’re performing and what are the bottlenecks? From the above URL it appears that disk I/O is first, but if there’s enough of that available then CPU usage is second. I’m not quite sure where most of the memory goes - caching? - I’m guessing users are doing relatively few searches compared to how many new emails are being indexed/deleted all the time?

[Dovecot] Postfix delivers mails to maildir and not to dovecot LDA for a virtual user
by Tru Pheenix 06 Nov '13

06 Nov '13

Hi I have been able to setup postfix and dovecot using postgres as the backend store with virtual user maps on Ubuntu 12.04 LTS Server. I have been following instructions from here: http://wiki2.dovecot.org/HowTo/DovecotPostgresql I haven't setup postfix to use saslauthd and PAM, instead I am using dovecot for SASL authentication. Rest of the table structures and query files are the same as from the wiki. SASL authentication works correctly for SMTP POP IMAP. I am able to send emails from a mail client such as Thunderbird with SASL authentication. However I am not able to receive emails for virtual users. I cannot figure out why. System users are getting their emails in the mail box correctly. Postfix fires the mailbox_command to hand over the mail to dovecot. This is how my *mail.log* looks when I send emails from an external domain: Nov 6 06:48:21 localhost postfix/smtpd[20053]: E075280C52: client= mail-ee0-f41.google.com[74.125.83.41] Nov 6 06:48:22 localhost postfix/cleanup[20064]: E075280C52: message-id=< CAJ+V0eCU891rSzSMVbcSy4zsRUk5GUp58b70Wv_WgZxLbKuyLw(a)mail.gmail.com> Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: from=< me(a)gmail.com>, size=3124, nrcpt=1 (queue active) *Nov 6 06:48:22 localhost postfix/virtual[20066]: E075280C52: to=<someone(a)mydomain.com <someone(a)mydomain.com>>, relay=virtual, delay=0.85, delays=0.7/0.02/0/0.13, dsn=2.0.0, status=sent (delivered to maildir)* Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: removed Nov 6 06:48:22 localhost postfix/smtpd[20053]: disconnect from mail-ee0-f41.google.com[74.125.83.41] Postfix seems to deliver the mail to maildir instead of the home directory of the virtual user.

[Dovecot] Missing i_stream_unref in imap_msgpart_crlf_seek()?
by Tomasz Potega 06 Nov '13

06 Nov '13

Hi, imap_msgpart_crlf_seek() returns an error stream in case of problems in message_skip_virtual(). The original input stream is not being unreferenced, preventing destroy callbacks from being executed. Shouldn't we have an i_stream_unref(&input) here: src/lib-imap-storage/imap-msgpart.c: 398 if (message_skip_virtual(input, virtual_skip, &cr_skipped) < 0) { 399 errinput = i_stream_create_error(errno); 400 i_stream_set_name(errinput, i_stream_get_name(input)); 401 return errinput; 402 } ?

[Dovecot] 2.2.6 auth process crash using LMTP and LDAP on director.
by Olivier Girard 06 Nov '13

06 Nov '13

I'm upgrading my configuration to use director and lmtp for delivery. (doveconf -n at end of the mail). I use the same config for auth on mail backends and see no errors. My setup seem to work nicely but i have some auth process crashing when using lmtp protocol. Everything is working a sexpected then i've got 5-6 errors like this in logs and a crach of the auth process: dovecot: lmtp(47269): Error: passdb lookup(_mail_): Disconnected unexpectedly pid 47406 (auth), uid 143: exited on signal 11 Actually, i didn't configure to core dump. Do you think seting up lmtp protocol to static auth adding something like folow will be better for this problem? protocol lmtp { passdb { args = proxy=y nopassword=y driver = static } } Please note that my configuration is actually listening on inet fot LMTP but that the goal is to configure postfix on the same server and switch to socket, this expain the configuration of the service auth to provide a socket to postfix. Here is my director config: % doveconf -n # 2.2.6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.4-RELEASE-p4 amd64 auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = sha1 default_process_limit = 4000 director_mail_servers = 192.168.16.1 192.168.16.2 192.168.16.3 director_servers = 192.168.16.4 192.168.16.5 192.168.16.6 disable_plaintext_auth = no doveadm_port = 24245 info_log_path = syslog instance_name = director lmtp_proxy = yes mail_debug = yes 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 passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } service anvil { client_limit = 12003 } service auth-worker { process_min_avail = 10 user = $default_internal_user } service auth { client_limit = 16000 unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 user = $default_internal_user } user = $default_internal_user } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { address = 192.168.16.4 port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service doveadm { inet_listener { port = 24245 } } service imap-login { executable = imap-login director } service lmtp { inet_listener lmtp { address = * :: port = 24 } } service pop3-login { executable = pop3-login director } ssl_cert = </etc/ssl/cert/mail.univ-angers.fr.pem ssl_key = </etc/ssl/cert/mail.univ-angers.fr.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { auth_socket_path = director-userdb } protocol doveadm { auth_socket_path = director-userdb } local 192.168.16.0/24/24 { doveadm_password = mysecret } Last thing, in my config file, there is only one /24 on local network but this is another problem.

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] v2.2.7 released

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

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

Hi, is it possible to run a script right after the IMAP/POP3 session was started? I know about post-login scripting but this is probably not what i'm looking for. I need to run a script which will know PID of process running IMAP session (so it must be already started). Thank you. azur

[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 '/'?

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

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

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. You can rule out a lot of the crazier options by answering the questions, (a) What attack scenario do you have in mind? (b) How will encryption help?

[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

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] 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?

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 ...

[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. Thanks, -Mark

Re: [Dovecot] Dbox group file permissions
by Chris Lasater 28 Oct '13

28 Oct '13

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?

[Dovecot] Plugin issue with update from 2.0.19 to 2.1.17
by Reinaldo Matukuma 26 Oct '13

26 Oct '13

Hello. Probably only Timo can help-me with this. I have a self-made plugin based on the zlib plugin that i use to cryptograph the messages at inbox. As a side-effect of the cryptography, my plugin changes the size of the message, but until 2.0.19 this works well with dovecot index and the W/S flags. But now, i'm going to upgrade to 2.1.17 and now i have these messages on log at my test ambiance: Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Cached message size smaller than expected (367 < 529) Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Maildir filename has wrong S value, renamed the file from /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/cur/1381879158.M634385P5208.test,S=367,W=378:2,S to /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/cur/1381879158.M634385P5208.test,S=529:2,S Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Corrupted index cache file /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 6 I understood with these messages that the dovecot is arguing to get the real size of the file now, overriding the return of size from my crypto plugin. But i don't understood if this is a consequence from the changes to correct the index issue (the dovecot.index.cache issue). So... I want know if the correct way to fix this would be change my plugin to return the real size of the file (that will be larger than the effective message that the plugin returne after the de-cryptography) or if i need use some new function to the plugin replace the expected size based on the real size of the message, not of the file. Thanks Reinaldo

Using Dovecot v2.2.5.4; I see: # doveadm -v -o imapc_user=user(a)example.com -o imapc_password=password -o imapc_host=imap.example.com -o imapc_port=993 -o imapc_ssl=imaps -o imapc_ssl_dir=/etc/ssl -o imapc_feature=rfc822.size -o imapc_ssl_verify=no sync -1 -R -u user(a)example.com imapc: dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8343, msgid=<4F387A25.5010900(a)example.com>, size=2954969 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8344, msgid=<5237B0BF.7030402(a)example.com>, size=3371710 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8345, msgid=<5237B588.6040009(a)example.com>, size=3266 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8346, msgid=<5237B6B4.2030203(a)example.com>, size=4201 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8347, msgid=<5237B888.7030807(a)example.com>, size=3371445 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8348, msgid=<5237C224.9010608(a)example.com>, size=3371745 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8349, msgid=<5237C350.5080608(a)example.com>, size=3371700 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8350, msgid=<5237C5EE.5030408(a)example.com>, size=3371619 dsync(user(a)example.com): Info: expunge: box=Drafts, uid=8209, msgid=< 4F387A25.5010900(a)example.com>, size=2954969 The interesting lines being uid=8209 and uid=8343; why would dsync both copy and then expunge the same message from the same mailbox?

[Dovecot] Strange output from LIST command
by azurIt 26 Oct '13

26 Oct '13

Hi, i'm using Dovecot 2.1.7 (Debian Wheezy) and output from LIST command looks strange: C: 4 LIST () "" (INBOX INBOX.Karantena INBOX.Spam) RETURN (STATUS (UNSEEN)) S: * LIST () "." "INBOX" S: * LIST () "." "INBOX.Karantena" S: * STATUS "INBOX.Karantena" (UNSEEN 0) S: * LIST () "." "INBOX.Spam" S: * STATUS "INBOX.Spam" (UNSEEN 0) S: 4 OK List completed. The UNSEEN information for INBOX is completely missing. It is correct behavior? If not, is this a known bug in 2.1.7? Thank you. azur

[Dovecot] Login into other user's account // master user for non-master users // chroot to users.<user>
by Steffen Kaiser 26 Oct '13

26 Oct '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Currently some of our organizational roles uses shared secrets (aka the password) to access the mail account of an organizational role, say "sales" for example. For one, I don't like shared secrets, for second, there had been some changes to shared mailboxes, I can only say "user sales has deleted the message at then and then". Therefore I would like to access the mailboxes of organizational roles with the accounts of the humans performing the role currently. Using sharing and ACLs it is possible to map the mailboxes of "sales" to "users.sales" namespace for specific other users, actually the human ones, say userA and userB for example. However, userB does not like managing identities in its MUA and refuses to acknowledge the messages in users.sales for various reasons. One reason was that userB wants to visibly separate strictly both mail accounts, the private messages in "userB" and the role's ones in "sales". Now, I came into thinking that it would be good in such case, if userB could authentificate as, say "sales*userB" - much like a master user - and ends in "sales"'s home, but with access permissions of "userB", well, like a chroot. Would it be an interesting feature to add to Dovecot's core? If I simulate "sales*userB" with password of userB and let the userdb return the home of sales, userB would gain "owner" privilegues of sales implicitly. So there seems to exist no workaround.

[Dovecot] LMTP, TLS/SSL, authentication, proxy
by Jogi Hofmüller 26 Oct '13

26 Oct '13

Folks, Several questions packed into one email ;) Can dovecot use TLS/SSL on LTMP inet socket? Can I configure dovecot to only let an authenticated user deliver mail via LMTP? Can I tell dovecot to use a user/password for proxying LMTP connections? All this is related to my quest to move from cyrus to dovecot transparently to our users. And if any of the above questions can be answered with yes, I would appreciate the odd hint on howto configure that :) Thanks in advance! -- j.hofmüller aka Thesix http://users.mur.at/thesix/

[Dovecot] Empty Mails from MAILER-DAEMON with Dovecot-Antispam and DSPAM
by Anna Christina Naß 26 Oct '13

26 Oct '13

Hallo, I've installed the dovecot-Antispam extension to my dovecot IMAP installation in conjunction with DSPAM. But when moving Mails from e.g. INBOX to Spam or vice versa, empty mails from MAILER-DAEMON appear after the original mail has been moved. This happens using Thunderbird 17esr, K-9 Mail on Android and Apple Mail (Mountain Lion). (Perhaps also when using a Webmail IMAP client) The source from one of these empty mails looks like this: ----snip---- Return-Path: <MAILER-DAEMON> X-Original-To: acn Delivered-To: acn(a)mydomain.name Received: from localhost (localhost.localdomain [127.0.0.1]) by <my host name> (Postfix) with SMTP id CB81B140011 for <acn>; Thu, 24 Oct 2013 09:23:33 +0200 (CEST) X-DSPAM-Reclassified: Spam Message-Id: <20131024072333.CB81B140011@<my host name>> Date: Thu, 24 Oct 2013 09:23:33 +0200 (CEST) From: MAILER-DAEMON ----/snip---- Do you have any idea why these mails appear and how I can prevent it?

[Dovecot] UIDL conversion courier -> dovecot
by Will Yardley 25 Oct '13

25 Oct '13

I've got a weird split setup where POP3 is currently handled by Courier (courier-imap-3.0.2 distribution), and IMAP is currently handled by the RHEL 5 version of Dovecot (1.0.7) I'm trying to figure out a way to convert the POP3 UIDLs (in cases where the courierpop3dsizelist is newer than dovecot-uidlist, at least) to something that Dovecot will read, or to configure Dovecot's pop3 to use a UIDL format that will work, as mentioned in the migration wiki. We have some "squeaky wheel" users who don't have their POP clients set to delete messages, and are likely to complain about re-downloading their several GB of mail. Thus far, the migration scripts haven't seemed to work properly, maybe because of the versions I'm using. I'm not sure whether the Courier versions there refer to Courier MTA version or Courier IMAP version, but adjusting the UIDL format to %v-%u (as suggested for early Courier 3 / Dovecot 1.0) hasn't worked (I saw %u-%v online, but that also didn't work). Since the Courier system doesn't seem to report validity, I also tried just '%u' - this works *if* I delete the header line as well as rename the courierpop3dsizelist to dovecot-uidlist, but I still don't get the exact same UIDLs as before. I'm willing to write my own migration tool, or to adapt the existing one, but I could use some assistance knowing how to do the translation. Dovecot -n for that instance is below, slightly sanitized, obviously I can change pop3_uidl_format; I also tried getting rid of pop3_reuse_xuidl: Basically, to give a concreate example, the Courier system seems to use the filename as the UIDL, with this courierpop3dsizelist: /2 45 1382654636 1199751891.13891_0.water-ox:2,Sa 2412 0:1382654636 1199927364.22870_0.fire-ox:2,S 2440 0:1382654636 1199936486.3332_0.wood-ox:2,Sa 2074 0:1382654636 1199985712.27745_0.water-ox:2,RS 4007 0:1382654636 1199993867.23139_0.fire-ox:2,S 1550 0:1382654636 producing this UIDL output: UIDL +OK 1 1199751891.13891_0.water-ox 2 1199927364.22870_0.fire-ox 3 1199936486.3332_0.wood-ox 4 1199985712.27745_0.water-ox 5 1199993867.23139_0.fire-ox [...] Dovecot's dovecot-uidlist: 3 V1199747645 N606 562 W2412 :1199751891.13891_0.water-ox:2,Sa 563 W2440 :1199927364.22870_0.fire-ox:2,S 564 W2074 :1199936486.3332_0.wood-ox:2,Sa 565 W4007 :1199985712.27745_0.water-ox:2,RS 566 W1550 :1199993867.23139_0.fire-ox:2,S producing: UIDL +OK 1 1199747645-562 2 1199747645-563 3 1199747645-564 4 1199747645-565 5 1199747645-566 (or, if I change the format to just %u): +OK 1 650 2 651 3 652 4 653 5 654 # dovecot --version 1.0.7 # 1.0.7: /etc/dovecot.d/XXX.cfg base_dir: /var/run/dovecot/pop-its syslog_facility: local4 protocols: pop3 pop3s listen: *:110 ssl_listen: *:995 ssl_ca_file: /etc/pki/dovecot/certs/XX.pem ssl_cert_file: /etc/pki/dovecot/certs/XXXX.pem ssl_key_file: /etc/pki/dovecot/private/XXXX.key disable_plaintext_auth: yes login_dir: /var/run/dovecot/pop-its/login login_executable: /usr/libexec/dovecot/pop3-login login_greeting_capability: yes login_processes_count: 4 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:/var/spool/maildir/%1Ln/%Ln:INDEX=/var/spool/dovecot/indexes/%1Ln/%Ln mail_debug: yes mmap_disable: yes maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_reuse_xuidl: yes pop3_uidl_format: %v-%u pop3_client_workarounds: outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: Mail. inbox: yes auth default: mechanisms: plain login passdb: driver: ldap args: /etc/dovecot.conf-ldap userdb: driver: static args: uid=vmail gid=mail home=/var/spool/maildir/%1Ln/%Ln socket: type: listen master: path: /var/run/dovecot/pop-its/auth-master mode: 384 user: vmail group: mail TIA! /wby

[Dovecot] Replication (Mac OS X)
by Rusty Ross 25 Oct '13

25 Oct '13

Hello, I am taking a stab at setting up dovecot replication between two OS X Mavericks servers. (The dovecot version in Mavericks is 2.2.5.) The first question I have is in regards to userdb. The user accounts are Open Directory based. The output of: doveadm user ‘*' …yields only: # doveadm user ‘*' submit However, specific user accounts can be looked up explicitly, ie: # doveadm user 'mary' field value uid 214 gid 6 home mail maildir:/Library/Server/Mail/Data/mail/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F quota maildir:User quota:noenforcing quota_rule *:storage=0 mail_location maildir:/Library/Server/Mail/Data/mail/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F sieve /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F/dovecot.sieve sieve_dir /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F sieve_storage /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F According to http://wiki2.dovecot.org/Replication, user listing via “doveadm user ‘*’” is required for replication. Any thoughts about how I can get that working (or work around it) in this environment? Thanks, Rusty

[Dovecot] Replication not happening on 2.2
by Lucas Rothamel - Eye Catching Webdesign 24 Oct '13

24 Oct '13

Hello, first - thanks for the help in getting dovecot 2.2 compiled and installed on Debian. I have Dovecot 2.2 running now on two servers, and to test replication, I am polling mail on one server whilst the other creates mail regularly from crontab output. I have replication set up, but nothing at all is appearing on the other server, and I do not have any dsync / doveadm messages in /var/log/mail.log any more. With 2.1, these two used to spam many errors into mail.log. Any hints?

Hello, i want to know if it's possible to use mailbox sharing with mdbox. I have done a setup with maildir where it's working fine but with mdbox I'm only able to subscribe the shared folder but there are no messages in it. (maybe a problem with the namespace) I'm running dovecot 2.2.6 [deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2.patched main ] on Debian Wheezy Kind regards Stefan

[Dovecot] Odd Feature Request - RBL blacklist lookup to prevent authentication
by Marc Perkel 23 Oct '13

23 Oct '13

I would like to have a list of IPs (hacker list) that I can do a lookup on so that if anyone tries to authenticate to dovecot they always fail if they are on my list. I have the list - and the list is available as a DNS blacklist. I'd like to have it work with both local IP lists or RBL lookup. The idea is so hackers from known IP addresses never succeed. If Dovecot provides the feature I have about 1/2 million IP addresses of known current hackers to block. Anyone else interested in this?

It did not. Any ideas why this is happening?

Surely there is a better way to do this? Looking at the code, it's trying to open the tty and turn off echo. For the record: FreeBSD 8.4-RELEASE-p3 And yes, there is no console.

[Dovecot] Dbox group file permissions
by Chris Lasater 21 Oct '13

21 Oct '13

Hi everyone, I feel like I am missing something obvious here. I have dovecot up and running and every piece of mail is given user read/write permission. I see the option mail_gid, but I do not see anyplace to set the group permissions. I see the below wiki talking about new home directories getting their permission from the parent directory, but this does not seem to work. Any assistance would be appreciated. http://wiki2.dovecot.org/SharedMailboxes/Permissions I changed the group permissions on the parent directory, and used rm -rf to delete the user directories, then logged in again so it was recreated. [user@dovecot ~]$ sudo ls -la /mnt/home/imapd/domain.example.net/ total 24 drwxr-x--- 6 imapd imapd 4096 Oct 21 17:35 . drwxr-xr-x 46 imapd nagios 4096 Oct 21 16:55 .. drwx------ 3 imapd imapd 4096 Oct 21 16:59 user1 drwx------ 3 imapd imapd 4096 Oct 21 17:35 user2 Setup Mail is written in dbox format CentOS 5.9 dovecot 2.2.6 NFS with director Mail Configs mail_home = /mnt/home/imapd/%d/%n mail_location = dbox:/mnt/home/imapd/%d/%n mail_uid = imapd mail_gid = imapd Thanks, Chris

[Dovecot] Mailboxes separated from IMAP server
by Reymer Antonio Vargas Solano 21 Oct '13

21 Oct '13

Hello folks, At my university we are trying to implement a distributed email backend, but I have some troubles, The topology: Server A: Postfix+LMTP # MTA Server B: Dovecot+LMTP # Just mailboxes Server C: Dovecot # POP3/IMAP Right now the Server A can leave a received email to the Server B, but I don't know how to communicate Server C to the Server B to retrieve the emails. I think that we should use IMAP protocol, but I am confused about how to connect them, I don't know if we have to use a proxy IMAP server, or another thing. Can anyone give me an idea? Regards, Reymer Antonio Vargas Solano
