[Dovecot] Sieve - not functioning for additional email aliases.
by Jacek Osiecki 14 Jan '14

14 Jan '14

Hi, On one of my servers (old one, version 1.2.5) user reported that vacation message for basic address works fine, but not for the aliases. I know that this is an old version, but we can't simply switch them to the most current dovecot release without preparing and testing everything... So I'm rather asking for help with debugging the case :) This person has email my.name(a)olddomain.pl. However, they are switching to new domain - newdomain.pl - and it is becoming their main brand. So temporarily olddomain.pl is still their "home" domain, but there is a domain alias newdomain->olddomain. The sieve file is simple: forward message and reply with vacation: ---- require ["copy","vacation"]; # rule:[redirect] if anyof (true) { redirect :copy "my.boss(a)newdomain.pl"; vacation :days 1 :addresses ["my.name(a)olddomain.pl","my.name(a)newdomain.pl"] text: I'm unavailable now. Please contact my boss: my.boss(a)newdomain.pl Greetings . ; } ---- When I send email to my.name(a)olddomain.pl - it is sent to my.boss(a)newdomain.pl and I receive the vacation message. When I send it to the alias (my.name(a)newdomain.pl) - none of above is done. Any idea how I can debug it? Running test-sieve does not help - it claims that will simply forward and deliver the message... Greetings, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need.

[Dovecot] dict ldap
by me＠electronico.nc 14 Jan '14

14 Jan '14

Hello everybody, Dovecot 2.2.6 with LDAP auth against AD (Samba4). I would like to know if it's possible to specify an LDAP transport for dict (something like dovecot-dict-ldap.conf.ext). I'm in need to setup shared mailboxes and if I could query LDAP, that would help a lot. IE : user1 user2 user3 are in OU=group1, so group1 (setup as user in AD) would share its mailbox with user1 user2 and user3. Thanks in advance for your time. Nicolas

[Dovecot] Slow authentication performance when switching folder
by ra＠rz.uni-frankfurt.de 13 Jan '14

13 Jan '14

Hello, we have a problem with Dovecot 2.2.9 running on an AIX 7.1 and compiled with xlc. At first we configured passdb to use our ldap directory via pam and experienced an Internal login failure like the following one Jan 13 16:20:02 imap-login: Info: Internal login failure (pid=29818948 id=1) (internal failure, 1 successful auths): user=<user>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=yyy.yyy.yyy.yyy, TLS, session=<r/P1m9vv5ACNAv6j> I read that this error occurs if the last passdb returns a continue and there is no other passdb to ask. We added two more passdb to rule out that pam is the problem. We added ldap directly and as third a fallback passwd file, but we still get the Internal login failure. As far as i can see this only occurs if i switch to another folder and i´m being reauthenticated. Are there any suggestions on what is going wrong? Any push in the right direction would be appreciated. kind regards Manuel PS: This is the dump of our dovecot configuration file: doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (32768) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (24579) # OS: AIX 1 00F7B83D4C00 auth_debug = yes auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890- auth_username_format = %n auth_username_translation = AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz auth_verbose = yes base_dir = /var/run/dovecot-imap default_process_limit = 8192 disable_plaintext_auth = no first_valid_uid = 100 info_log_path = /mailbase/dovecot/2.2.9/log/dovecot_imap_debug.log log_path = /mailbase/dovecot/2.2.9/log/dovecot_imap.log login_greeting = University-Frankfurt-IMAP-Horde ready. mail_access_groups = mhs mail_debug = yes mail_fsync = never mail_location = mbox:~/:INBOX=/var/spool/mail/%u:INDEX=/var/mail-indexes/%u mailbox_idle_check_interval = 90 secs mbox_write_locks = fcntl namespace { inbox = yes location = prefix = separator = / type = private name = } passdb { args = username_format=%u /mailbase/etc/passwd driver = passwd-file } passdb { args = %s driver = pam } plugin { stats_refresh = 30 secs stats_track_cmds = yes } service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service { inet_listener { address = * port = 0 name = imap } inet_listener { address = * port = 993 name = imaps } name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service { inet_listener { address = 10.1.1.40 port = 0 name = pop3 } inet_listener { address = * port = 0 name = pop3s } name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } ssl_cert = </etc/ssl/certs/thot_mit_chain.crt ssl_key = </etc/ssl/certs/private_key_thot.rz.pem userdb { driver = passwd } userdb { args = /mailbase/dovecot/2.2.9/etc/dovecot/dovecot-ldap.conf driver = ldap } protocol imap { mail_plugins = " stats imap_stats" service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service imap { name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service pop3 { name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } }

[Dovecot] dsync error: gz trailer has wrong CRC value
by Joe Beaubien 13 Jan '14

13 Jan '14

A few days ago by dovecot installation started behaving weirdly. First it was doveadm fts optimize which would fail (a thread running about that) and now it's dsync, which means my backups are not working. This all started a few days ago, which I find a little weird, because I haven't messed around with the dovecot setup in months. I've been searching the internet, but didn't find anything useful yet. Would anyone know how to fix the errors in the log below?

[Dovecot] Dovecot quota with MySQL - username issue
by michael 11 Jan '14

11 Jan '14

Hi all, I'm using Dovecot 2.2.8 with quota using a MySQL backend. The Quota plugin is listed for POP3, IMAP and LDA. When it is enabled for LDA, it populates the "username" field in the MySQL table with e mail addresses. I end up with a mixture of email addresses and usernames, which causes things to not fully work. It *should* be just usernames. the LDA SQL statement is: user_query = \ SELECT mailboxes.username, accounts.uid, accounts.uid AS gid, \ concat('/home/',mailboxes.username) AS home, \ (SELECT IF(accounts.new_mail_fmt=1, \ CONCAT('Maildir:',home,'/Maildir'), \ CONCAT('mbox:',home,'/Maildir:INBOX=/var/spool/mail/',mailboxes.username))) AS mail_location \ FROM mailboxes JOIN accounts ON accounts.username=mailboxes.username \ WHERE (mailboxes.email='%u' || \ (mailboxes.email=CONCAT('@','%d') AND (SELECT COUNT(email) FROM mailboxes \ WHERE email='%u') = 0) AND mailboxes.active IS TRUE) It clearly knows the username. Usernames on this system are just names, not full email addresses. The configuration of Quota Dict is: dovecot.conf dict/quotadict = mysql:/etc/dovecot/dovecot-dict-sql.conf ... quota = dict:user::proxy::quotadict dovecot-dict-sql.conf map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Can this be fixed?

[Dovecot] Possible to force cipher order?
by Matthias Rieber 10 Jan '14

10 Jan '14

Hi, is it possible to force the server cipher order instead of the clients preferences? When I connect with openssl using these ciphers: 'RC4-SHA:DHE-RSA-AES256-GCM-SHA384' -> RC4-SHA will be selected and with 'DHE-RSA-AES256-GCM-SHA384:RC4-SHA' -> DHE-RSA-AES256-GCM-SHA384 It seems to be recommended for webservers to override that due to bad clients choices and increasing knowledge, like RC4 vs. BEAST, AES128 better (theoretical) than AES256. Regards, Matthias

[Dovecot] Message filtering capability at IMAP proxy
by CM Reddy 10 Jan '14

10 Jan '14

Hi, I would like process the messages at Dovecot IMAP proxy. In one of the documents, it was mentioned that Dovecot proxy currently supports on the fly message filtering in latest releases. Will it it possible to extend the filtering feature to handle the following requirements. 1. Parse the email at IMAP proxy. 2. Replace the links with some other secure links. 3. Replace the attachments with some other document. It would be great, if any one can provide some pointers to move forward. - Thanks in advance CM Reddy

You could also chmod 1777 /var/mail but this will allow arbitrary uses who have filesystem access to create their own files here, and maybe DoS a new user from being created (or maybe even anticipate a new mailbox, create one with mode 0777 and wait to intercept mail?).

[Dovecot] imap auto create mailbox: we're not in group 8(mail)
by Adrian Zaugg 09 Jan '14

09 Jan '14

Dear List Somehow I don't understand the intended work flow to have new mailboxes auto created. On login of a new user with no mailbox, I get 2014-01-09 12:53:06 imap(tester): Error: user tester: Initialization failed: Namespace '': mkdir(/var/mail/tester) failed: Permission denied (euid=1016(tester) egid=1016(tester) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0771) The imap process runs as the user the login performed and thus it has only the privileges of that user. This is good and desired, when a mailbox already exists. I do not want to allow all users to write to /var/mail, only they should write to their dirs inside /var/mail. Same story for LMTP, if no mailbox exists yet: 2014-01-09 13:01:47 lmtp(20416, tester): Error: user tester: Initialization failed: Namespace '': mkdir(/var/mail/tester) failed: Permission denied (euid=1016(tester) egid=1016(tester) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0771) How can I configure the auto create mailbox feature that it works and let run LMTP and IMAP process as user %u and group mail and let create the mailboxes in /var/mail as (example user tester) with the following permissions: /var/mail: drwxrwx--x root mail 3072 Dec 18 01:43 . drwx------ tester tester 1024 Jan 09 12:53 tester ...or do I need a different approach?

Re: [Dovecot] BUG report: doveadm HEADER <field> <pattern> when concatenating with another Search key

I tried using logical conjections of header searches and it works with my installation of dovecot, so either it's a bug introduced later than 2.1.16, or perhaps it from the different search engine you use (I use the default that comes with dovecot -- squat?).

[Dovecot] Disallow certain characters in foldernames?
by Charles Marcus 08 Jan '14

08 Jan '14

Is there a way to do this in dovecot? Similar to how you can When using Maildir and Thunderbird, if a user tries to a create folder named "test.1" or "test/1", dovecot will happily create a folder called "test", with a subfolder called "1". Worse, the top level folder "test" is greyed out, which is how Thunderbird displays a folder that can contain only other folders, not both folders and files. I want to disallow this. Obviously I'd prefer if Thunderbird would display a meaningful error, but most likely dovecot cannot control that. I don't really care if the user just gets some kind of weird generic error or not, I'd just prefer to prevent dovecot from creating the problematic folders, and explain the problem to the user if/when they call about it (after NOT reading my carefully crafted documentation explaining the illegal characters that cannot be used in foldernames). -- Best regards, Charles

[Dovecot] acl, shared folders

Hi list, After spending quite some time to figure out how users can share folders I now hope someone of you could help me out. I am quite sure its just a stupid mistake/misunderstanding ... I am using Ubuntu 12.04 LTS with the shipped dovecot 2.0.19 When I login via telnet as user1 I get the following: 1 create folder1 1 OK Create completed. 2 setacl folder1 user2 rli 2 OK Setacl complete. 3 getacl folder1 * ACL "folder1" "user2" ilr "user1" lrwstipekxacd 3 OK Getacl completed. This seems fine. However, there is nothing listed in the account of user2. I think the mistake is in the namespace configuration of "location" or "prefix" Please help!

[Dovecot] LMTP with virtual and system users
by Philipp Kolmann 08 Jan '14

08 Jan '14

Hi, I have a mailsystem where i have some local users with shell access and full home dirs which receive mail and also several SQL virtual users only for mail. With the virtual users, everything works fine. Mail is delivered via LMTP and also sieve works :) The SQL Lookup knows what to do with username(a)domain.com The problem is the system user. If exim delivers the mail to the lmtp socket, the LMTPd can't find username(a)local.host I would be able to specify the global auth_username_format=%n but then my SQL queries break and I like the possibility to have xx(a)domain1.com and xx(a)domain2.com routed to two different accounts. As I have seen in the source, I can't specify username_format=%n in the passdb { driver = pam } backend. Do you have any suggestion how to solve this issue? thanks Philipp

[Dovecot] Question re: filesystem permissions
by Charles Marcus 08 Jan '14

08 Jan '14

Hi all, I want to make sure the filesystems are correct/optimal and secure as possible. This is a virtual hosting setup only (no system users), and dovecot is currently running in high performance mode (I'm thinking I want to change that too, so wondering if that would affect the permissions)... /var/vmail (and everything under it) is owned by vmail:vmail. Current permissions are: /var/vmail 755 /var/vmail/example1.com 777 /var/vmail/example2.com 777 /var/vmail/example1.com/user1 755 (all other user home dirs are the same) /var/vmail/example1.com/user1/Maildir 700 (all other user Maildirs and all subdirs are the same) All files are 600, with the exception of the dovecot-uidvalidity.blahblah files, which are 444 So... is this right? Anything need to be changed? Thanks, -- Best regards, Charles

[Dovecot] virtual mailboxes folder structure
by Marco Cusano 08 Jan '14

Hi, I am trying to find a way to list my virtual mailboxes hiding the namespace prefix into my imap client. Fore example now my “All” mailbox is listed under virtual/ as: Inbox Sent Drafts Spam Trash - virtual All I would like to list as this: Inbox Sent Drafts Spam Trash All This is my 10-mail.conf: http://pastebin.com/DumEbbmy and this is my 15-mailboxes.conf: http://pastebin.com/QFzWGzyC I thought that the list = children paramenter would do but it did not.

Re: [Dovecot] BUG report: doveadm HEADER <field> <pattern> when concatenating with another Search key

Hey Joseph! Thanks for testing. > I couldn't recreate this with 2.1.16. Also, my version of "doveadm > search" does not accept missing header patterns. Is this corroborated > by dumping out the header with this same search query? > > doveadm fetch -u exampleuser hdr SUBJECT Silvester \ > HEADER Return-Path someuser at example.com Yes, it's same phenomenon when dumping with fetch. Of course you can only test this properly when you really have some mails with corresponding existing Header fields. (You can also try out other HEADER fields, like Reply-To, References, X-Spam-Score or whatever - just look at some mail headers of your mails and try it with existing fields.) So E.g. When doing doveadm fetch -u exampleuser hdr SUBJECT Silvester HEADER Return-Path someuser(a)example.com it initially outputs 13 headers (same as when using with SUBJECT Silvester only) , when piping it to "grep -i 'Return-Path'" it even found only 3 out of 13 headers containing a Return-Path at all, 2 of them different than someuser(a)example.com - so SAME behaviour as with search. Maybe also relevant, as mail format I'm using sdbox (on a larger user base of 40.000 people). -- (relevant part) of dovecot -n # 2.2.5.5 (e5350245ad9b): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.23.2.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.4 (Santiago) nfs auth_cache_size = 100 M auth_cache_ttl = 10 mins auth_master_user_separator = * auth_mechanisms = plain login auth_username_format = %Ln auth_verbose = yes disable_plaintext_auth = no import_environment = TZ DEBUG_OUTOFMEM DOVECOT_HOSTDOMAIN listen = * lock_method = dotlock mail_fsync = always mail_home = /mnt/nfs/vmails/%u mail_location = sdbox:/mnt/nfs/vmails/%u/mail:ALT=/mnt/archivnfs/vmails/%u/mail mail_plugins = " quota fts fts_lucene" mail_privileged_group = mail 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 mmap_disable = yes service imap-login { process_limit = 200 process_min_avail = 8 service_count = 0 vsz_limit = 512 M } service imap { client_limit = 1 process_limit = 10000 } service pop3-login { process_limit = 200 process_min_avail = 8 } service pop3 { process_limit = 10000 } verbose_proctitle = yes protocol lda { mail_plugins = " quota fts fts_lucene sieve" } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 50 mail_plugins = " quota fts fts_lucene imap_quota" } _________________________________________________________________ Send and receive anonymous emails to your inbox with InboxAlias. http://www.inboxalias.com

[Dovecot] how to separate virtual delivery and authentication?
by Mihai Badici 08 Jan '14

08 Jan '14

I have a "pure ldap" setting with postfix and dovecot. When using dovecot delivery, the recipient is checked via ldap. The same ldap query is used when authenticate. So, if I want to authenticate with the uid , I can't use a filter like uid=%u because the delivery will fail. I don't want to use %nor something else because I could use multiple e-mail addresses on a single account. I actually use a filter like ( mail=%u)|(uid=%u) but I think for more complex situations should be better to have two separate filters, one for authentication and the other for the delivery. What is your oppinion? -- Mihai Bădici http://mihai.badici.ro

[Dovecot] Dovecot can't find CLucene's libstemmer on FreeBSD
by interfaSys sàrl 08 Jan '14

Hello, A set of patches was created by Lawrence Chen for the Dovecot2 port so that it could recognise and use libstemmer and libexttextcat. They can't be used as is as he's replacing statements with something that works only on FreeBSD, but I think it would be a good idea to try and include some of his fixes. http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/175813 Cheers, Olivier

Re: [Dovecot] using OR in doveadm search query

I guess > because now the query has become a mailbox name that does not exist. ( I > am using dovecot 2.2.9) Each search token ought to be a command line argument to doveadm, so if you're looking for all message with the string "a" or "b" in the subject in mailboxes shared/*, then this should be the correct syntax, with all arguments sufficiently escaped from shell interpretation: doveadm search mailbox shared/\* $ SUBJECT a OR SUBJECT b $ (Delete "OR" if both strings must be in the subject: expressions are implicitly AND'd if not OR'd. In fact, you can also remove the parenthesis since precedence doesn't matter anymore.) You can check the search query by fetching some values using the same query: doveadm fetch 'mailbox hdr' mailbox shared/\* $ SUBJECT a OR SUBJECT b $ Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Mailbox autocreate feature cannot create folders
by interfaSys sàrl 08 Jan '14

08 Jan '14

Hello, The "new" way of creating default mailboxes doesn't work for us. There seems to be a permission problem. We get this in the logs: imap(testuser(a)domain.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy That error message has nothing to do with NFS (not used) or /var/mail and appears every time an app is requesting a list of folders via IMAP and only if we enable the autocreate feature. We're using mdbox, emails are delivered via LDA and the folder permissions look like this: # la /home/user/imap/domain.com/testuser/mdbox/mailboxes/ total 5 drwx------ 3 user mail 3B Jan 5 19:33 INBOX drwx------ 3 user mail 3B Jan 5 19:33 . drwx------ 4 user mail 8B Jan 7 02:43 .. The mailbox definitions used come straight from the wiki: http://wiki2.dovecot.org/MailboxSettings I've enabled debugging, but there is no mention of the mailboxes to create: Debug: dict quota... Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mdbox Debug: fs:... Debug: acl:... ... Here is what works: - Autocreate plugin - Creating folders via various clients So, it seems Dovecot can create folders, just not using that feature. If that's not a bug, would there be a way to make it work without altering permissions? Cheers, Olivier

[Dovecot] need assistance migrating between apple servers

I am attempting to move imap folders from an Apple Snow Leopard server to a new Apple Mavericks server. Dovecot --version is not working , but I believe the old server is running dovecot 1.1.2 and can confirm the new one is running 2.2.x. I have tried taring and moving folders, but have not been able to get the transfered messages and folders to show up in user accounts (new messages show up fine). I have attempted to recreate index files, but that has not worked either. The last attempt I made to migrate was to use dsync, but it does not exist on the old server and I do not see a way to install it. What method would work best to migrate or move files and folders from the old server and get them to show up for clients on using the new server? -- Raymond Norton LCTN 952.955.7766 Sent from My Desktop

[Dovecot] [SIEVE] Locking Errors with vnd.dovecot.duplicate Extension

Hi, we are running a 4 host setup which each hosts a director+mailbox which is mounted via NFSv4 from a DRBD cluster. * Dovecot upstream release 2.1.16 * Doveadm batch subcommand fix - http://hg.dovecot.org/dovecot-2.1/raw-rev/850b5d8bbcc9 * Pigeonhole release 0.3.4 Now we would like to remove duplicate Mails using the vnd.dovecot.duplicate extension using a SIEVE script like this: require ["vnd.dovecot.duplicate", "fileinto", "mailbox", "regex", "vacation", "variables"]; if duplicate { fileinto :create "Trash"; } But as soon as we start delivering duplicate mails, we're sometimes getting locking errors from the mailbox (which is responsible for the user) according to the director: Dec 27 16:36:30 10.129.3.213 dovecot: lmtp(27975, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:33 10.129.3.213 dovecot: lmtp(27987, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:35 10.129.3.213 dovecot: lmtp(27994, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28011, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28013, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:38 10.129.3.213 dovecot: lmtp(28017, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:39 10.129.3.213 dovecot: lmtp(28025, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:42 10.129.3.213 dovecot: lmtp(28037, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:43 10.129.3.213 dovecot: lmtp(27973, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Configs and Error log is attached.

I would really love to get rid of all those folders created by all those different mail clients just because they can't agree to use the same folder for special purpose. Obviously clients need to support it too.

[Dovecot] Allow both SSL/993 and STARTTLS/143 connections (secure only)
by Charles Marcus 03 Jan '14

03 Jan '14

Hi all, Ok, up until now, I've only always allowed IMAPS connections to dovecot on port 993. I want to also start allowing clients to user port143+STARTTLS, but I walso want to make sure both ports are locked down to ONLY allow secure connections. So... is disable_plaintext_auth = yes in the main config enough to accomplish this? http://wiki2.dovecot.org/SSL/DovecotConfiguration says: There are a couple of different ways to specify when SSL/TLS is required: * disable_plaintext_auth=yes allows plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms> only when SSL/TLS is used first. * ssl = required requires SSL/TLS also for non-plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms>. * If you have only plaintext mechanisms enabled (auth { mechanisms = plain login } ), you can use either (or both) of the above settings. They behave exactly the same way then and the comments in 10-auth.conf say: # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP # matches the local IP (ie. you're connecting from the same computer), the # connection is considered secure and plaintext authentication is allowed. # See also ssl=required setting. #disable_plaintext_auth = yes These seem to be saying that all I need to do is set either or both (ssl-required and/or disable_plaintext_auth=yes). I'm looking for the simplest, and don't like redundant/unnecessary settings, so... which is the best/preferred way? And what is the difference between ssl=required and disable_plaintext_auth=yes?

I am getting an error that autogen.sh is missing from pigeonhole 0.4.2 source (as available from: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.2.tar…) /var/tmp/rpm-tmp.89185: line 92: /home/mockbuild/rpmbuild/BUILD/dovecot-2.2.10/dovecot-2.2-pigeonhole-0.4.2/autogen.sh: No such file or directory Indeed, the file is missing, as: tar --list -f dovecot-2.2-pigeonhole-0.4.2.tar.gz | grep autogen ...produces no output. However, I managed to use the latest source code: http://hg.rename-it.nl/dovecot-2.2-pigeonhole/shortlog/32beba3bfd8d which does contain an autogen.sh, and this package worked fine. I guess the released source tar pack should be updated? Thanks and regards, Nick

[Dovecot] Dovecot doesn't seem to read userdb for the first delivery
by phuhimself＠phunehehe.net 02 Jan '14

02 Jan '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello List, First of all, this is my first post so please bear with me if I miss something. I'm using Postfix with Dovecot 2.0.19 as the LDA. The home directory is of the form `/var/mail/virtual/<domain>/<username>`. The mail directory is under the home directory and named `mail`. `mail_location` is left empty, and userdb is specified using SQL: user_query = SELECT uid AS uid, \ gid AS gid, \ homedir AS home, \ maildir AS mail \ FROM users WHERE email = '%u' Everything had been fine, until I added a new user. In the log, Dovecot complains that it doesn't have permission to create the mail directory (email address replaced): > Jan 2 05:46:19 mail1 dovecot: lda(test(a)test.com): Error: user > test(a)test.com: > Initialization failed: Initializing mail storage from mail_location > setting > failed: mkdir(mail) in directory /var/spool/postfix failed: Permission > denied > (euid=5000(virtual) egid=5000(virtual) missing +w perm: > /var/spool/postfix, > dir owned by 0:0 mode=0755) Sometimes it complains about /run/dovecot instead of /var/spool/postfix, but I think that doesn't really matter. I think not specifying `mail_location` confused Dovecot, as explained in [MailLocation][1]. When I put in the right value for `mail_location` the error went away. What I don't understand is, it is said in the [same document][1] that the userdb field `mail` will override `mail_location` anyway. I would think that I can skip `mail_location` if I specify userdb `mail` for all users. Is the document wrong?

[Dovecot] How to add dovecot plugin?
by Timothy Murphy 31 Dec '13

31 Dec '13

I'm running dovecot version 2.0.9 under CentOS-6.5 . I want to add the following plugin: ==================== require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "Spam"; } ==================== Could some kind soul tell me where exactly I should place this script (eg "anywhere in /etc/dovecot/dovecot.conf" or "anywhere in /etc/dovecot/conf.d/90-plugin.conf"), and do I need to take any other action? Actually, the folder I should like spam to go to is ~/Maildir/.Spam/cur/ - should I modify the above script? If these queries are anwered clearly in some dovecot documentation, please point me to that. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

[Dovecot] dovecot 2.2.10 - imap: Error: Can't load plugin imap_stats_plugin:
by giovanni＠neweden.uk.to 30 Dec '13

30 Dec '13

dovecot 2.2.10 is raising this error on my installation. Dec 30 13:57:59 imap: Error: Can't load plugin imap_stats_plugin: Plugin stats must be loaded also (you must set: mail_plugins=$mail_plugins stats) Dec 30 13:57:59 imap: Fatal: Couldn't load required plugins This error occurs at logging phase. The dovecot configuration looks correct to me, here below an excerpt of it: ... ... mail_plugins=$mail_plugins stats protocol imap { mail_plugins = $mail_plugins imap_stats } plugin { # how often to session statistics stats_refresh = 30 secs # track per-IMAP command statistics stats_track_cmds = yes } ... ... I was already using this configuration but only now I am getting this error. From STRACE I see that the stat plugin is correctly localed . Is anybody else getting this error? or am I missing something? Here below an except of the strace message.
