Inexplicable missing permissions issue
by Nelson Crosby 21 Sep '17

21 Sep '17

Greetings all. I've been having great difficulty getting Dovecot working. I'm getting stuck with using mbox directories outside of /home. Dovecot keeps giving me this message: imap(ncrosby): Namespace '': stat(/var/logmail/mbox/ncrosby) failed: Permis sion denied (euid=1001(ncrosby) egid=1001(ncrosby) missing +w perm: /var/lo gmail/mbox/ncrosby stat(/var/logmail/mbox/ncrosby) failed: Permission denie d, dir owned by 0:0 mode=0755) in=0 out=340 I've tried letting Dovecot create this directory, I've tried creating this directory manually and giving it any permission I can think of, I've tried playing about with the permissions throughout the entire /var/logmail tree, but to no avail. Below is my setup. I appreciate any input. Here's `tree -apug /var/logmail`: /var/logmail ├── [drwx------ root root ] lost+found ├── [drwxr-xr-x root root ] mbox └── [drwxrwxr-x root mail ] spool ├── [-rw-rw---- fedora mail ] fedora └── [-rw-rw---- ncrosby mail ] ncrosby 3 directories, 2 files And permissions for `/var/logmail` itself: drwxr-xr-x. 5 root root 4096 Sep 19 01:52 . And now `doveconf -n`: # 2.2.31 (65cde28): /etc/dovecot/dovecot.conf # OS: Linux 4.11.8-300.fc26.x86_64 x86_64 Fedora release 26 (Twenty Six) ext4 disable_plaintext_auth = no mail_location = mbox:/var/logmail/mbox/%n:INBOX=/var/logmail/spool/%n mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = dovecot driver = pam } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_cipher_list = PROFILE=SYSTEM ssl_key = # hidden, use -P to show it userdb { driver = passwd } -- // Nelson Crosby /* nc(a)sourcecomb.com */

sieve stopped working and doveadm mailbox list without -s shows less folders then with
by Ralf Becker 20 Sep '17

Dovecot 2.2.31 with mailboxes in mdbox format. Since a couple of days some mailboxes have the problem, that sieve rules moving mails to folders stop working and .sieve.log in mailbox shows: sieve: info: started log at Sep 07 13:57:17. error: msgid=<20170907155704.EGroupware.S4yThVJRr12WSiJLpKbK0Bz(a)somedomain.egroupware.de>: failed to store into mailbox 'INBOX/Munser': Mailbox doesn't exist: INBOX/Munser. When I do a doveadm mailbox list -s -u <user>@<domain> I get all folders incl. the one mentioned above, while doveadm mailbox list without -s shows just user INBOX I already tried doveadm force-resync -u <user>@<domain> INBOX, but it did not change anything. I also moved the mailbox in filesystem to an other name and tried to restore it from there, which helped with most broken mailbox problems in the pre 2.2.31 aftermath, but that failed completly: /var/dovecot/imap/<domain> # mv <user> <user>.broken /var/dovecot/imap/<domain> # doveadm force-resync -u <user>@<domain> INBOX /var/dovecot/imap/<domain> # sudo -u dovecot doveadm -Dv import -u <user>@<domain> -s mdbox:$(pwd)/<user>.broken/mdbox INBOX all Debug: Loading modules from directory: /usr/lib/dovecot Debug: Module loaded: /usr/lib/dovecot/lib01_acl_plugin.so Debug: Module loaded: /usr/lib/dovecot/lib10_quota_plugin.so Debug: Module loaded: /usr/lib/dovecot/lib15_notify_plugin.so Debug: Module loaded: /usr/lib/dovecot/lib20_mail_log_plugin.so Debug: Module loaded: /usr/lib/dovecot/lib20_replication_plugin.so Debug: Loading modules from directory: /usr/lib/dovecot/doveadm Debug: Module loaded: /usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: Error relocating /usr/lib/dovecot/doveadm/lib10_doveadm_expire_plugin.so: expire_set_lookup: symbol not found (this is usually intentional, so just ignore this message) Debug: Module loaded: /usr/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so Debug: Module loaded: /usr/lib/dovecot/doveadm/lib10_doveadm_sieve_plugin.so Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: Error relocating /usr/lib/dovecot/doveadm/lib20_doveadm_fts_plugin.so: fts_backend_rescan: symbol not found (this is usually intentional, so just ignore this message) Debug: Skipping module doveadm_mail_crypt_plugin, because dlopen() failed: Error relocating /usr/lib/dovecot/doveadm/libdoveadm_mail_crypt_plugin.so: mail_crypt_box_get_public_key: symbol not found (this is usually intentional, so just ignore this message) doveadm(<user>@<domain> 54303): Debug: Added userdb setting: plugin/master_user=<user>@<domain> doveadm(<user>@<domain> 54303): Debug: Added userdb setting: plugin/userdb_acl_groups=admins@<domain>,hts büro@<domain>,hts@<domain> doveadm(<user>@<domain> 54303): Debug: Added userdb setting: plugin/userdb_quota_rule=*:bytes=10485760000 doveadm(<user>@<domain>): Debug: Effective uid=90, gid=101, home=/var/dovecot/imap/<domain>/<user> doveadm(<user>@<domain>): Debug: Quota root: name=User quota backend=dict args=:ns=INBOX/:file:/var/dovecot/imap/<domain>/<user>/dovecot-quota doveadm(<user>@<domain>): Debug: Quota rule: root=User quota mailbox=* bytes=107374182400 messages=0 doveadm(<user>@<domain>): Debug: Quota grace: root=User quota bytes=10737418240 (10%) doveadm(<user>@<domain>): Debug: dict quota: user=<user>@<domain>, uri=file:/var/dovecot/imap/<domain>/<user>/dovecot-quota, noenforcing=0 doveadm(<user>@<domain>): Debug: Namespace inboxes: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=no location=mdbox:~/mdbox doveadm(<user>@<domain>): Debug: fs: root=/var/dovecot/imap/<domain>/<user>/mdbox, index=, indexpvt=, control=, inbox=, alt= doveadm(<user>@<domain>): Debug: acl: initializing backend with data: vfile doveadm(<user>@<domain>): Debug: acl: acl username = <user>@<domain> doveadm(<user>@<domain>): Debug: acl: owner = 0 doveadm(<user>@<domain>): Debug: acl vfile: Global ACLs disabled doveadm(<user>@<domain>): Debug: Namespace users: type=shared, prefix=user/%n/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:%h/mdbox:INDEXPVT=~/shared/%u doveadm(<user>@<domain>): Debug: shared: root=/run/dovecot, index=, indexpvt=, control=, inbox=, alt= doveadm(<user>@<domain>): Debug: acl: initializing backend with data: vfile doveadm(<user>@<domain>): Debug: acl: acl username = <user>@<domain> doveadm(<user>@<domain>): Debug: acl: owner = 0 doveadm(<user>@<domain>): Debug: acl vfile: Global ACLs disabled doveadm(<user>@<domain>): Debug: Namespace subs: type=private, prefix=, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mdbox:~/mdbox doveadm(<user>@<domain>): Debug: fs: root=/var/dovecot/imap/<domain>/<user>/mdbox, index=, indexpvt=, control=, inbox=, alt= doveadm(<user>@<domain>): Debug: acl: initializing backend with data: vfile doveadm(<user>@<domain>): Debug: acl: acl username = <user>@<domain> doveadm(<user>@<domain>): Debug: acl: owner = 0 doveadm(<user>@<domain>): Debug: acl vfile: Global ACLs disabled doveadm(<user>@<domain>): Debug: quota: quota_over_flag check: quota_over_script unset -

Thanks for taking a look. > this is owned by root, and it's complaining about > /var/logmail/**mbox**/ncrosby > and dovecot cannot create this because mbox is only writable by root That's definitely not the issue. As I explained, I've played with permissions through the entire /var/logmail tree (including the /var/logmail/mbox directory). Another configuration in which the exact same message occurs (including the exact same statement about being owned by 0:0): /var/logmail |-- [drwx------ root root ] lost+found |-- [drwxrwxr-x root mail ] mbox | `-- [drwxr-xr-x ncrosby ncrosby ] ncrosby `-- [drwxrwxr-x root mail ] spool |-- [-rw-rw---- fedora mail ] fedora `-- [-rw-rw---- ncrosby mail ] ncrosby 4 directories, 2 files Your time is appreciated; // Nelson -- // Nelson Crosby /* nelsonc(a)sourcecomb.com */

lazy_expunge doesn't work since upgrade 2.2.30 to 2.2.32
by Harald Leithner 19 Sep '17

19 Sep '17

Hi, it seams that the lazy_expunge plugin doesn't work for me after the upgrade... 2.2.32 cry's about plugin { lazy_expunge_only_last_instance=no } is most likely handled as 'yes' - remove the setting completely to disable it. If this is intentional, add quotes around the value: lazy_expunge_only_last_instance="no" I changed it to lazy_expunge_only_last_instance="no" and tried to remove it but doesn't change the problem.

logins fail for virtual users (permission denied, we're not in group 5000)
by Paul Schreiber 17 Sep '17

I have: - Ubuntu 17.04 - Dovecot 2.2.27 (c0f36b0) - Postfix 3.1.4 - regular unix users with mail in /home/bob/Maildir - virtual users with mail in /var/mail/vhosts/domain.com/bob/ The regular users can receive mail as expected. When virtual users try to log in, it fails.

What INTERNALDATE does dovecot with mbox storage set on a COPY'd message?
by Steinar Bang 15 Sep '17

15 Sep '17

When a message is copied to a folder on dovecot with mbox storage, is the mtime of the saved mbox file set to the time of the save? Or is the mtime set to the Date: field of the source message that is saved? If there is a difference in the behaviour, do someone know the dovecot version number where the change happened? The reason I'm asking is a problem reported on the Gnus imap client in August 2016, where messaged moved by Gnus showed up with the wrong order and/or wrong date in other imap clients. (The reason for the different message ordering was that the other clients use the INTERNALDATE and that was changed to the time of message move when Gnus was used. Gnus use the Date of the source message) Thanks! - Steinar (Gnus user)

[RFC master-2.2 0/1] Support OpenSSL 1.1 API for setting allowed TLS versions
by Apollon Oikonomopoulos 14 Sep '17

14 Sep '17

Hi, I came up with the following patch while trying to figure out a good solution for the situation described in Debian bug #871987[1]. In short, OpenSSL in Debian unstable has disabled TLSv1.0 and TLSv1.1 *by default*. That means that unless an application requests otherwise, only TLSv1.2 is supported. In the world of e-mail this is seemingly an issue, as there are still way too many old clients out there supporting only TLSv1 or TLSv1.1. Now, traditionally OpenSSL 0.9.8/1.0 used SSL_CTX_set_options() to allow *disabling* specific protocols, without offering a way to enable previously disabled protocols. OpenSSL 1.1 introduced a dedicated API[2] to set allowed protocol versions, taking a linear version approach: the application may request a minimum and a maximum allowed version (inclusive), allowing all versions inbetween as well. Dovecot's existing ssl_protocols option is probably not ideal to use with this new "linear" model. Instead, I introduced two new options, ssl_min_proto_version and ssl_max_proto_version, that map directly to OpenSSL 1.1 concepts. I have tested the patch with both OpenSSL 1.0 and OpenSSL 1.1. With OpenSSL 1.1 it works as expected; with OpenSSL 1.0 it doesn't seem to break anything. Other than that, this is a first version; I'm sure there are still things to improve, so comments are welcome :) Regards, Apollon [1] https://bugs.debian.org/871987 [2] https://www.openssl.org/docs/man1.1.0/ssl/SSL_CTX_set_min_proto_version.html Apollon Oikonomopoulos (1): Support setting min/max SSL protocol version doc/example-config/conf.d/10-ssl.conf | 4 ++++ src/config/config-parser.c | 25 +++++++++++++++++++++ src/lib-master/master-service-ssl-settings.c | 4 ++++ src/lib-master/master-service-ssl-settings.h | 2 ++ src/lib-master/master-service-ssl.c | 2 ++ src/lib-ssl-iostream/iostream-openssl-common.c | 12 +++++++++++ src/lib-ssl-iostream/iostream-openssl.h | 1 + src/lib-ssl-iostream/iostream-ssl.h | 2 ++ src/login-common/ssl-proxy-openssl.c | 30 ++++++++++++++++++++++++++ 9 files changed, 82 insertions(+) -- 2.14.1

disable imap for ldap user
by Markus Rosjat 13 Sep '17

13 Sep '17

hi there, I have a LDAP dir with an attribute set to 0 or 1 and in my old setup (a courier server) I used this attribute to map it to an authoption called disableimap. This prevent users to access the mailbox with imap protocol. So the question is what should I set in dovecot to get the same behaviour? I looked at the docs but the part with the pass_ilter and service doesn't really fit. Some advice would be appreciated regards -- Markus Rosjat fon: +49 351 8107223 mail: rosjat(a)ghweb.de G+H Webservice GbR Gorzolla, Herrmann Königsbrücker Str. 70, 01099 Dresden http://www.ghweb.de fon: +49 351 8107220 fax: +49 351 8107227 Bitte prüfen Sie, ob diese Mail wirklich ausgedruckt werden muss!

Problems to configure IMAP Quota
by Jacques Belin 13 Sep '17

13 Sep '17

Hello, We manage a mail server using Dovecot under Debian. Since a long time, we run nightly a script permitting to display the storage usage of each user on the webmail, using internal calls. The usage on each mailbox is stored in a Mysql database. For several reasons, we would now want to use the IMAP quota feature, not only to let users have the quota displayed from their Mail clients. But testing that features, I encounter two problems : 1) It seems that when we use the sql dict, a map contaning the patern "priv/quota/limit/messages" is mandatory. Not specifying it in dovecot-dict-sql.conf.ext issues an error. As we are interested only by the storage size and don't want to process the number of messages, how to get rid of it ? 2) We store the storage value in kilobytes. But the plugin seems to only accept storage in bytes, Is there any way to let know to dovecot that the value stored in the database is in kilobytes ? (of course, I tried to put "size/1024" in the value_field field of the map. It works, but generate a lot of error lines in the dovecot log as it create a syntaxly incorrect MySQL uodate request...) Jacques. -- The last man connected to the Interet was browsing some old WebSites. "You have new mail" appeared on the screen... --------------------------- adapted from a short Fredric Brown's story

Problem w/ Dovecot authentication against AD
by Garry Glendown 13 Sep '17

13 Sep '17

Hi, I had to start using Dovecot on a machine as the new OS does not come with Cyrus IMAP anymore. After multiple problems, I managed to get everything working, including LDAP authentication against the (old) Novell LDAP server. Anyway, the authentication is supposed to be migrated to the new Windows AD. For other tools, I successfully migrated the config to use AD, but somehow Dovecot does not work as it should. I've been going back and forth, trying everything I could think of, but still can't get it to work. Here's the excerpt from the config file: hosts = 10.10.10.210 uris = ldap://10.10.10.210:389 dn = cn=Administrator,cn=Users,dc=srv,dc=SLD,dc=net dnpass = PASSWORD tls = no debug_level = -1 auth_bind = yes ldap_version = 3 base = DC=srv,dc=SLD,dc=net deref = never scope = subtree user_attrs = sAMAccountName=user user_filter = (&(sAMAccountName=%n)(objectclass=person)) pass_attrs = sAMAccountName=user pass_filter = (&(sAMAccountName=%n)(objectclass=person)) iterate_attrs = mail=user iterate_filter = (objectclass=person) default_pass_scheme = PLAIN The problem might be caused by the referal-info sent by the AD, which I can see both in the results dovecot gets (checked with tcpdump), as well as in ldapsearch ... apart from the actual search result, I always get three additional results: # refldap://DomainDnsZones.srv.SLD.net/DC=DomainDnsZones,DC=srv,DC=SLD,DC=net # refldap://ForestDnsZones.srv.SLD.net/DC=ForestDnsZones,DC=srv,DC=SLD,DC=net # refldap://srv.SLD.net/CN=Configuration,DC=srv,DC=SLD,DC=net >From what I can see in the pcap as well as some of the logs, dovecot binds to the AD, sends out the LDAP query correctly, gets the lookup result with the user queried plus the above three referrals, then unbinds from the (named) bind, attempts a simple bind without dn/dnpass (multiple times), and finally sends three additional search requests under the search bases cn=Configuration,DC=srv,DC=SLD,DC=net DC=ForestDnsZones,DC=srv,DC=SLD,DC=net DC=DomainDnsZones,DC=srv,DC=SLD,DC=net These three requests are denied by the AD as they are not permitted without a successful prior bind. Dovecot then fails the auth process. Is there a way to stop Dovecot from using the referals? Openldap seems to have an option to disable referals, but Dovecot does not allow that option in its LDAP config, and having the option set in the global ldap.conf doesn't seem to help any, either. Is there possibly a way to disable the referal information on the AD side? Thanks, Garry -- PGP Fingerprint: A79F A33F 5B13 BEB7 A51D 274F F99C 3AE2 4BCB 7015

(I'm assuming that's how these hooks work -- it's called after cert renewal using the same credentials as the certbot.) If you use privilege separation, and run the certbot as a regular user process, this won't work. You might have this scenario if, for example using the context of web serving, you serve many virtual sites with different owners, and you don't want give each owner administrative access.

Dynamic host with password plugin
by Jorge Bastos 12 Sep '17

12 Sep '17

Howdy, I’m making my multi-server instalation ready, but I’m facing just one small issue, that is with password plugin. So, in config.inc.php of it I have: config['password_db_dsn'] = 'mysql://webmail:bdkddddddz@192.168.69.222/postfix'; but, as I’m using in roundcube’s config.inc.php “dynamic” host: $config['default_host'] = 'mail.%s'; Can I have in the password plugin config.inc.php the same variable? (I can use same user/password/db on both servers for password change) Thanks in advanced,

Won't work, of course, if you employ the least-privilege security principle and run the certbot as a non-privileged user. You'll need a script with administrator privileges to detect cert renewals and restart the service. I can't willy-nilly restart dovecot to pick up renewed certs without webmail disruptions.

I am running Ubuntu 16.04. I am following this guide: https://wiki2.dovecot.org/HowTo/AntispamWithSieve. At the end when I try to compile the .sieve files, I get this error: sievec(root): Fatal: Plugin 'sieve_imapsieve' not found from directory /usr/lib/dovecot/modules/sieve. Does anyone know about this? I have dovecot-sieve installed and I'm using Postfix and Spamassassin. -- Mika Leppänen -- mika.leppanen(a)iki.fi

By "same pairs", I assume you mean key and certificate. Yes, just as long as you use the same Subject for all your services (e.g. "mail.yourdomain.com") or you have purchased a wildcard certificate e.g. "*.yourdomain.com" to authenticate "webmail.yourdomain.com", "imap.yourdomain.com", "smtp.yourdomain.com", etc.) Certificates do not authenticate services or protocols, but server names (typically).

Returning error response to the client from passdb (with dict protocol)
by Nagy, Attila 11 Sep '17

11 Sep '17

Hi, When using a passdb with (UNIX socket) dict protocol, I can return a JSON with fields. When I want to deny the user, I can send a JSON like this: {"fail":true} which yields (on POP) a friendly -ERR [AUTH] Authentication failed. Is it possible to return the response text itself? I want to tell the user why the authentication has failed.

Fail2ban 'Password mismatch' regex
by James Brown 11 Sep '17

11 Sep '17

I have turned on 'auth_debug_passwords=yes’ in dovecot.conf. I’m trying to get Fail2ban to detect this log line: Sep 11 15:52:49 mail dovecot[54239]: auth-worker(10094): sql(user(a)bordo.com.au <mailto:user@bordo.com.au>,::1,<L2xqieNYeM4AAAAAAAAAAAAAAAAAAAAB>): Password mismatch (given password: 2) I’ve added it as the last line of my dovecot filter regex: failregex = ^%(__prefix_line)s(%(__pam_auth)s($dovecot:auth$)?:)?\s+authentication failure; logname=\S* uid=\S* euid=\S* tty=dovecot ruser=\S* rhost=<HOST>(\s+user=\S*)?\s*$ ^%(__prefix_line)s(pop3|imap)-login: (Info: )?(Aborted login|Disconnected)(: Inactivity)? $((auth failed, \d+ attempts)( in \d+ secs)?|tried to use (disabled|disallo$ ^%(__prefix_line)s(Info|dovecot: auth\(default$|auth-worker$\d+$): pam$\S+,<HOST>$: pam_authenticate failed: (User not known to the underlying authentication$ ^%(__prefix_line)s(auth|auth-worker$\d+$): (pam|passwd-file)$\S+,<HOST>$: unknown user\s*$ ^%(__prefix_line)s(auth|auth-worker$\d+$): Info: ldap$\S*,<HOST>,\S*$: invalid credentials\s*$ ^%(__prefix_line)sauth: Info: sql$\S+,<HOST>$: (Password mismatch|unknown user)( $(SHA1 of given password: [0-9a-f]{5,40}|given password: \w*)$)?$ Have spent ages googling and trying different variations. Does anyone have a fail2ban regex that would work on the above Dovecot log line? (Running latest versions of Dovecot and fail2ban) Many thanks, James.

Is it possible to disable pipelining in imapc?
by Nagy, Attila 11 Sep '17

11 Sep '17

Hi, I've a broken IMAP server, which doesn't support pipelining and fails on dovecot's attempt to do this ([C] is dovecot's imapc, [S] is the IMAP server): [C] 24 LOGIN "user" "pass" [S] 23 OK [C] 25 SELECT "INBOX" [C] 23 UID FETCH 2 (INTERNALDATE) [S] 25 OK [S] 23 BAD No mailbox selected Sadly, fixing the server would be a hard task, turning off pipelining in dovecot's imapc (which already supports many workarounds for different servers) could be easy... ... except I can see no place to do this in imapc (only in pop3c and imap proxy, which I guess doesn't apply here). If I'm right, may I ask for a knob for such dumb servers? Thanks,

Per-user quota (passwd)
by Evgeniy Korneechev 11 Sep '17

Hello! We have passwd=pam, userdb=passwd. passdb { driver = pam #server was entered domain Active Directory } userdb { driver = passwd override_fields = home=/var/vmail/glu_vrem/%u } How can i use per-user quota? Only passwd-file? I tried: userdb { args = /etc/imap.passwd driver = passwd-file override_fields = home=/var/vmail/glu_vrem/%u } /etc/imap.passwd: administrator:*:95400500:95400513:Administrator:/home/DOM/administrator:/bin/bash::userdb_quota_rule=*:bytes=10G Authentication and quota - now OK. But doesn't work sending and receiving mail... postfix say 'Unknown user'... Is there "extra_field" in passwd-file for email? What generally will be advice on quotas in our case? dovecot -n: # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.4.39-std-def-alt0.M80P.1 x86_64 ALT 8.1 Server auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_socket_path = /var/run/dovecot/auth-userdb auth_username_chars = auth_verbose = yes auth_verbose_passwords = plain base_dir = /var/run/dovecot/ debug_log_path = /var/log/dovecot disable_plaintext_auth = no first_valid_gid = 502 first_valid_uid = 502 last_valid_gid = 268999999 last_valid_uid = 268999999 log_path = /var/log/dovecot login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_access_groups = vmail mail_debug = yes mail_gid = 502 mail_location = maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_plugins = " quota autocreate" mail_privileged_group = vmail mail_uid = 502 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 index ihave duplicate mime foreverypart extracttext imapflags notify mbox_write_locks = fcntl namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota_rule = *:storage=5G recipient_delimiter = + sieve = /etc/dovecot/sieves/default.sieve sieve_default = /etc/dovecot/sieves/default.sieve sieve_dir = ~/sieve sieve_extensions = +notify +imapflags sieve_max_redirects = 8 } protocols = imap pop3 lmtp sieve service auth-worker { user = root } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } } service imap { process_limit = 1024 vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service managesieve-login { inet_listener sieve { port = 4190 } vsz_limit = 64 M } service pop3-login { inet_listener pop3 { port = 110 } } service pop3 { process_limit = 1024 } ssl_ca = </usr/share/ca-certificates/ca-bundle.crt ssl_cert = </etc/dovecot/server.crt ssl_key = # hidden, use -P to show it userdb { driver = passwd override_fields = home=/var/vmail/glu_vrem/%u } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = " quota autocreate sieve" } protocol lda { mail_plugins = " quota autocreate sieve quota" plugin { quota = dict:user::file:/var/vmail/glu_vrem/%n/.quotausage } } protocol imap { mail_plugins = " quota autocreate autocreate imap_quota" plugin { autocreate = INBOX autocreate2 = Sent autocreate3 = Trash autocreate4 = Drafts autocreate5 = Junk autosubscribe = INBOX autosubscribe2 = Sent autosubscribe3 = Trash autosubscribe4 = Drafts autosubscribe5 = Junk quota = dict:user::file:/var/vmail/glu_vrem/%n/.quotausage } } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } -- WBR, Korneechev Evgeniy BaseALT/ALTLinux Team
