[Dovecot] Dovecot, AD and authenticated binds...
by Jeroen Scheerder 03 Mar '14

03 Mar '14

I posted earlier with reports of less than stellar success in using Active Directory for dovecot authentication. My approach is to using the two-step approach of - obtaining the user DN by a search using an authenticated bind (using a service account) - then binding as that DN, and returning the relevant user attributes This hasn't been succesful. Dovecot's authentication process does perform the (first) authenticated bind successfully, it does obtain the right DN, than just sits there doing nothing as far as I can tell, and after a long delay concludes authentication failure - shortly before deciding to perform the bind with the user-supplied credentials, successfully. Source inspection has not resulted in a glorious eureka yet. So I thought, why not handle it myself? And I wrote a little script, using the checkpassword interface. I've enclosed it. The script is based on <http://wiki2.dovecot.org/AuthDatabase/CheckPassword>, but somehow the userdb_uid and userdb_gid I've passed back in the "EXTRA" environment variable get lost along the way. It syslogs, and the syslogs show that the LDAP parts working as expected: Mar 3 14:49:09 <mail.info> ponyboy checkpassword: successful authenticated bind and DN(js) lookup Mar 3 14:49:09 <mail.info> ponyboy checkpassword: DN(js) is CN=Jeroen Scheerder,OU=Users,OU=Netherlands,OU=ON2IT,DC=office,DC=on2it,DC=net Mar 3 14:49:09 <mail.info> ponyboy checkpassword: js authenticated In dovecot's log, simultaneously, I see basically a successful login, except that the (user_)uid and (userdb_)gid work - unless I disable prefetch, and use a static userdb: Mar 03 14:49:04 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Mar 03 14:49:04 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 03 14:49:04 auth: Debug: auth client connected (pid=90856) Mar 03 14:49:09 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=+qFODbTzDgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=63246 resp=<hidden> Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): execute: /usr/local/etc/dovecot/checkpassword-on2it /usr/local/libexec/dovecot/checkpassword-reply Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): Received input: userdb_uid=143 userdb_gid=143 Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): exit_status=0 Mar 03 14:49:09 auth: Debug: client passdb out: OK 1 user=js Mar 03 14:49:09 auth: Debug: master in: REQUEST 4007395329 90856 1 29571963894e557ab643d2e51872ba55 session_pid=90899 request_auth_token Mar 03 14:49:09 auth: Debug: prefetch(js,127.0.0.1,<+qFODbTzDgB/AAAB>): success Mar 03 14:49:09 auth: Debug: master userdb out: USER 4007395329 js uid=143 gid=143 auth_token=e2d7c2463dd4c039010e904afb4ea45214cb7de5 Mar 03 14:49:09 imap-login: Info: Login: user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=90899, secured, session=<+qFODbTzDgB/AAAB> Mar 03 14:49:09 imap: Error: user js: Mail access for users with UID 143 not permitted (see first_valid_uid in config file, uid from userdb lookup).

[Dovecot] Tracking logins
by Alex 03 Mar '14

03 Mar '14

Hi, I'm using dovecot-2.1.17 on fc18 and wondered if there is some mechanism, perhaps a database, that can store the logins/logouts for each user? I realize there's something already logged to syslog, but I'd like more of a history. While lastlog is great for users that actually login, my dovecot users don't login, just check email via pop and imap. Any ideas greatly appreciated. Thanks, Alex

Hello; We are using maildir quotas and have found differences in many users in respect to what system command are showing and doveadm quotas. For example, four user test, we have: doveadm quota get -u test Quota name Type Value Limit % STORAGE 98066 102400 95 MESSAGE 883 - 0 But if we check user mail_location with "du" system command we get he is using 70458 Kb. We are running dovecot 2.1.17 ¿any clue? Thanks in advance.

[Dovecot] No speed improvement with FTS for iOS 7?
by Nicholas Riley 02 Mar '14

02 Mar '14

Hi, I recompiled Dovecot with Lucene FTS to try to improve iOS 7 IMAP search speed. Unfortunately this does not seem to help. I have 60 mailboxes, totaling 300 MB; lucene-indexes is 30 MB in size. % doveadm mailbox status -t all '*' messages=16335 recent=0 unseen=1736 vsize=280049586 Searching for a single word which is present in two messages of one mailbox takes 40 seconds to return. This is true whether or not fts is enabled. doveadm search takes much less than 1 second to do the same search. % time doveadm search BODY cython d8f09230c97af952b60c0000c1443b93 1 d8f09230c97af952b60c0000c1443b93 2 doveadm search BODY cython 0.18s user 0.05s system 99% cpu 0.230 total With fts disabled, it takes about 6.5 seconds. This is still a long way from 40 seconds. Is there any way I can make dovecot perform better here? Thanks, -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] + prefix in dovecot-virtual
by Nicholas Riley 01 Mar '14

01 Mar '14

Hi, The "+" prefix in dovecot-virtual does not seem to be documented. only discovered it because I tried to include a mailbox whose name began with + and Dovecot gave me an error when I tried to copy to it. I see it was added here: http://hg.dovecot.org/dovecot-2.2/rev/be0f0de75e34 My dovecot-virtual file looked like this: !+/2014-03 +/2014-02 all I just added another + to the second line and it seems to work. I don't care about \Recent thankfully but is there a better way to specify a mailbox whose name begins with +? Thanks. -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] Force SSL authentication per user basis
by Urban Loesch 28 Feb '14

28 Feb '14

Hi, I'm searching a way to force encrypted connections for POP3/IMAP on a per user basis. To not break clients which still connect in plaintext (there are still many of it) I must implement a mechanism to force encrypted connections on a per user basis. The users and passwords are stored in a mysql database. So there would be no problem to expand the database with a column like "ssl_tls" -> yes/no. The problem now: how can I get dovecot to process this field in the right way? I searched the list and googled about such a way, but I can't find any solution. My Dovecot version is 2.2.12. Many thanks and regards Urban Loesch

[Dovecot] Logging authentication failures when Dovecot's auth service used to authenticate postfix smtpd
by MV 28 Feb '14

28 Feb '14

Hello, tl;dr: Is there a way to get dovecot's auth to log failed smtp authentications without having to switch on "auth_verbose"? postfix version 2.11.0 and dovecot version 2.2.12 I'm currently migrating my postfix+courier to postfix+dovecot and so far it's working as expected. Except for logging smtp login failures. Despite Postfix logging successful authentications (see sample below), it doesn't log failed smtp logins. Feb 25 22:28:53 mailer2 postfix/submission[20274]: C981B20198: client=A-B-C-D.*****.net[A.B.C.D]:63107, sasl_method=PLAIN, sasl_username=joe(a)example.net And since my postfix setup authenticates virtual users through Dovecot's auth, I thought maybe dovecot could report smtp login failures the same way it reports imap and pop3 login failures. Below is a sample extracted from "info_log_path" after several imap and pop3 login failures. (Obviously the IP 255.... is made up and irrelevant for this mater). # begin extract "/var/log/dovecot-info.log" 2014-02-27 21:14:26 auth: Info: passwd-file(joe(a)example.net,255.255.255.255,<Y0lbzmnzfwAuQV80>): Password mismatch 2014-02-27 21:16:46 auth: Info: passwd-file(foobar,255.255.255.255,<Y0lbzmnzfwAuQV80>): unknown user 2014-02-27 21:52:00 auth: Info: passwd-file(foo(a)example.net,255.255.255.255,<0Su6VGrzGwAuQV80>): unknown user 2014-02-27 21:53:35 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Empty username 2014-02-27 21:53:55 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Username character disallowed by auth_username_chars: 0x5c (username: \0) 2014-02-27 22:08:05 auth: Info: plain(?,255.255.255.255): invalid input 2014-02-27 22:09:36 auth: Info: passwd-file(joe(a)example.net,255.255.255.255): Password mismatch 2014-02-27 22:09:53 auth: Info: login(?,255.255.255.255): Empty username # end extract I've tried adding "-L -o info_log_path=/var/log/dovecot-info.log" to the both auth and auth-worker services but that yield nothing. ----------------------%<-------------------------------- auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot/ info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/virtual_users driver = passwd-file } userdb { args = username_format=%u /etc/dovecot/virtual_users default_fields = uid=vmail gid=vmail driver = passwd-file override_fields = home=/home/vmail/%d/%u result_failure = return-fail result_internalfail = return-fail } service auth-worker { executable = auth -w -L -o info_log_path=/var/log/dovecot-info.log } service auth { executable = auth -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix user = postfix mode = 0660 } } service lmtp { executable = lmtp -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix mode = 0660 } } ---------------------->%-------------------------------- The relevant postfix config is ... smtpd_sasl_type = dovecot smtpd_sasl_path = private/dovecot-auth virtual_transport = lmtp:unix:private/dovecot-lmtp

[Dovecot] Dovecot2 vs. AD, "Inactivity during authentication"
by Jeroen Scheerder 28 Feb '14

28 Feb '14

Hi, I'm trying to setup Dovecot2 for o IMAP client access o LDA for postfix mail delivery (with SIEVE) ... on a FreeBSD host. The FreeBSD server has no users (by intention), so I've set up a virtual mail domain, using LDAP lookups in Postfix. So far so good. Mail delivers into the proper mailbox. But I'm stuck getting Dovecot to authenticate. User- and passwd DB's are set up for LDAP lookups to AD, using an authenticated bind (the AD server offers no anonymous binds, yet). I've enabled all the debugging I can find, but my logs have little information to offer. Any help in getting me a step further would be much appreciated. In particular, I'd like to learn how do diagnose these userdb/passdb issues properly. Here's what I see in the logs: Feb 27 12:25:49 <mail.info> ponyboy dovecot: imap-login: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 172 secs): user=<>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<r/ERi2HzQAB/AAAB> Feb 27 12:26:42 <mail.err> ponyboy dovecot: auth: Error: PLAIN(js,127.0.0.1,<r/ERi2HzQAB/AAAB>): Request 74099.1 timed out after 225 secs, state=1 This logging is related to the folloging IMAP session: ponyboy% telnet localhost 143 Trying 127.0.0.1...

[Dovecot] Quota-Status issue
by Cyberonic Turbo 27 Feb '14

27 Feb '14

Following this guide: http://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/ I can't seem to get it to work, as soon as I add the smtpd_recipient_restrictions setting to postfix I can no longer send mail at all. I get the message SMTP Error (450): Failed to add recipient "postmaster(a)example.com" (4.7.1 : Recipient address rejected: Internal error occurred. Refer to server log for more information.). I googled around and found this command to test the quota-status service: printf "recipient=postmaster at example.com\nsize=1234\n\n" | nc 127.0.0.1 12340 It seems to always return the quota_status_nouser message. I'm really stumped here. What logs do I need to check for errors and does anyone have any experience with this? I'm running Dovect 2.2.10 with Postfix 2.6.6 Here's my dovecot -n result: # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.5.1.el6.x86_64 x86_64 CentOS release 6.5 (Final) auth_master_user_separator = * auth_mechanisms = PLAIN LOGIN dict { acl = mysql:/etc/dovecot/dovecot-share-folder.conf quotadict = mysql:/etc/dovecot/dovecot-used-quota.conf } first_valid_uid = 2000 last_valid_uid = 2000 listen = * log_path = /var/log/dovecot.log mail_gid = 2000 mail_location = maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_plugins = quota mail_uid = 2000 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 { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/%%Lh/Maildir/:INDEX=/%%Lh/Maildir/Shared/%%u prefix = Shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } passdb { args = /etc/dovecot/dovecot-master-users-password driver = passwd-file master = yes } plugin { acl = vfile acl_shared_dict = proxy::acl auth_socket_path = /var/run/dovecot/auth-master autocreate = INBOX autocreate2 = Sent autocreate3 = Trash autocreate4 = Drafts autocreate5 = Junk autosubscribe = INBOX autosubscribe2 = Sent autosubscribe3 = Trash autosubscribe4 = Drafts autosubscribe5 = Junk quota = dict:user::proxy::quotadict quota_grace = 10%% quota_rule = *:storage=1G quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO quota_warning = storage=85%% quota-warning 85 %u quota_warning2 = storage=90%% quota-warning 90 %u quota_warning3 = storage=95%% quota-warning 95 %u sieve = /%Lh/sieve/dovecot.sieve sieve_dir = /%Lh/sieve sieve_global_dir = /var/vmail/sieve sieve_global_path = /var/vmail/sieve/dovecot.sieve } protocols = pop3 imap sieve service auth { unix_listener /var/spool/postfix/dovecot-auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { group = vmail mode = 0666 user = vmail } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service imap-login { process_limit = 500 service_count = 1 } service pop3-login { service_count = 1 } service quota-status { client_limit = 1 executable = quota-status -p postfix inet_listener { port = 12340 } } service quota-warning { executable = script /usr/local/bin/dovecot-quota-warning.sh unix_listener quota-warning { group = vmail mode = 0660 user = vmail } } ssl = required ssl_cert = </etc/pki/tls/certs/iRedMail_CA.pem ssl_key = </etc/pki/tls/private/iRedMail.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { auth_socket_path = /var/run/dovecot/auth-master lda_mailbox_autocreate = yes log_path = /var/log/sieve.log mail_plugins = quota sieve autocreate postmaster_address = root } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = quota imap_quota autocreate } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } For my postfix/main.cf I have this relevant setting: smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unlisted_recipient, check_policy_service inet:127.0.0.1:7777, check_policy_service inet:127.0.0.1:10031, check_policy_service inet:127.0.0.1:12340, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination

[Dovecot] dsync mirror to mailstores in director setup
by Murray Trainer 27 Feb '14

27 Feb '14

Hi All, I have dsync mirror command working between a standalone dovecot server and a backend mailstore in a Dovecot Director setup. Is it safe to do the dsync directly to the backend mailstore in this setup? It doesn't seem to work via the director proxy. Thanks Murray

[Dovecot] 2 users database on same LDAP with different mail location
by Francesco 26 Feb '14

26 Feb '14

Hello, i know i know, i'm getting annoying but appearently i always come up with weird ideas and i cant seem to accomplish such a task. the scenario is that i have an LDAP server with a bunch of users. some of them are in a specific OU, and i'd like to define for all these users belonging to this OU an alternative mail location/storage. in details for all the users i'd like to use maildir storage in a directory, while for the users belonging to a specific OU i'd like to use dbox with an alternative storage attached. so i created 2 userdb like this: userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-maildir.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-dbox.conf.ext } and then defined these 2 args files: maildir: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/vmail/%$ dbox: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = OU=dboxusers,OU=lowpriority,DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/local_dbox/%$, =mail=dbox:/var/local_dbox/%$:ALT=/var/iscsi_dbox/%$ user_filter = (&(ObjectClass=person)(mail=%u)) yet it doesn't matter how hard i try if i send an email to a user belonging to the dboxusers OU i still have the user to be addressed to the maildir storage in /var/vmail am i missing something? Thanks Francesco

[Dovecot] Dovecot upgrade 1 to 2 on Debian Squeeze : broken /var/run/dovecot
by Si L 26 Feb '14

26 Feb '14

Hi, I just upgraded from version 1 to version on Debian Squeeze using their backports. Like I expected my dovecot1 config had to be converted using doveconf and this I did. However, I see problems with files inside directory: drwxr-xr-x 4 dovenull root 4096 Feb 25 20:35 /var/run/dovecot All of them were created owned by root:root rw. I tried to changed, for example : chown postfix:dovecot /var/run/dovecot/auth-master but noticed when I restarted dovecot it reset the permissions back to root:root rw. Here's the version: # dovecot --version 2.1.7 Here's my slightly redacted conf. # grep -v ^# dovecot.conf|grep -v ^$ auth_mechanisms = plain login auth_verbose = yes dict { quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no first_valid_uid = 106 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/var/xx/%d/%u/ mail_plugins = quota mail_privileged_group = mail maildir_very_dirty_syncs = yes passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { quota_rule = *:storage=262144:messages=20000 quota_rule2 = Trash:storage=282144:messages=23000 } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = root } service imap-login { chroot = login inet_listener imap { address = 127.0.0.1 port = 3993 } inet_listener imaps { address = * port = 993 } process_limit = 256 process_min_avail = 24 service_count = 1 vsz_limit = 48 M } service pop3-login { chroot = login process_limit = 256 process_min_avail = 24 service_count = 1 vsz_limit = 48 M } ssl = required ssl_ca = </etc/ssl/certs/xxx.combined_for_dovecot.pem ssl_cert = </etc/ssl/private/xx.xx.xx.crt ssl_cipher_list = TLSv1+HIGH:!SSLv2:RC4+MEDIUM:!aNULL:!eNULL:!3DES:@STRENGTH ssl_key = </etc/ssl/private/xx.xx.xx.key ssl_verify_client_cert = yes userdb { args = uid=5000 gid=5000 home=/var/xx/%d/%u allow_all_users=yes driver = static } userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } valid_chroot_dirs = /var/xx protocol imap { mail_max_userip_connections = 96 mail_plugins = quota imap_quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = sieve quota postmaster_address = xxxx@xxxxx } I really don't understand how I should make this work, and the after I read the docs on dovecot.org and googled I realised I was really lost getting this back up and runing :( I should be really grateful if somebody would give me some advice. Thanks, Soph'

[Dovecot] Upgrading from 1.2.x -> 2.2.x in one step possible
by Götz Reinicke - IT Koordinator 26 Feb '14

26 Feb '14

Hi, after some off-ML discussions to and some reconsiderations, we might do the "big jump" from our current 1.2.17 to the atrpms 2.2. From googling and reading the dovecot upgrade wiki I don't see any (big) pitfalls. Basically we use the default config options, mbox, pop3s/imaps on RH EL 5. So "just" run the upgrade-config script, fingers crossed and thats it? Ii it possible to do such a big step form 1.2 to 2.2? Thanks for comments and suggestions .

[Dovecot] Removing Mount Points
by Jeff Geiger 26 Feb '14

26 Feb '14

Dovecot version 2.1.7 If a dovecot mount point (drive) dies, and the data is restored into the same path that's no longer a mount point (subfolder), dovecot complains about a missing mount point. Is it safe to do a `doveadm mount remove {path}` to fix the error since it's no longer a legit mount point? Example: We were storing indexes on an SSD drive mounted at /mnt/ssd. That drive died. I was able to put everything back into the /mnt/ssd folder (no longer mounted, just a folder). Everything seems to be working as expected. But, when I just went to dsync an account from another server to this one, I got the following error: dsync(sales(a)foo.com): Error: Couldn't create index dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Can't create mailbox root dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Mountpoint /mnt/ssd isn't mounted. Mount it or remove it with doveadm mount remove Would doing a `doveadm mount remove /mnt/ssd` fix my issue, or cause some type of catastrophe? Thanks, Jeff Geiger jeff.geiger(a)firespring.com

Re: [Dovecot] AUTH_USER variable has invalid value in checkpassword Script
by dovecot.pkoch＠dfgh.net 26 Feb '14

26 Feb '14

answering my own questions: > This has somehow changed and now AUTH_USER always > contains the username. This has fatal consequences as no > every owner of a valid certificate can logon as any user. I now use auth_ssl_username_from_cert = yes and this temporarily fixes my problem. Now if user A authenticates with his certificate and claims to be user B he will be logged on as user A. With ssl_username_from_cert = no (default) he was logged in as User B. > I'm absolutely sure that the value of the x500UniqueIdentifier > was stored into the AUTH_USER when I tested my setup > last year. If one looks at the source code, in particular routine env_put_auth_vars() in src/auth/db-checkpassword.c and routine auth_request_get_var_expand_table() in src/auth/auth-request.c it is clear, that this has never worked. The environemnt variable AUTH_USER always contais the username (in all Dovecot versions). It dows NOT contain the Dovecot auth_user-variable. Comparing AUTH_USER with the username makes no sense in a checkpassword-script So here's my next question: How do I find out the original username from within a chackpassword script after it has been replaced by the x500UniqueIdentifier value from a client certificate? Why is request->requested_login_user == NULL in env_put_auth_vars(). request->user contains the x500UniqueIdentifier value from the clients certificate so the original username was replaced and therefore should have been moved into request->requested_login_user. Kind regards Peter Koch
