NFS INTR mount option
by Murray Trainer 18 Aug '14

18 Aug '14

Hi again, We have our mailboxes on several NFS filesystems mounted with the options below. 10.11.0.238:/mailbox_store_01 on /home1 type nfs4 (rw,noatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,nordirplus,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.11.0.95,local_lock=none,addr=10.110.238) On the rare occasions that the NFS mounts hang, the system load goes through the roof and I often have to reboot the mailstore server as dovecot process are hung and can't be killed. Will the NFS INTR mount option help in this situation? Thanks Murray Send EMAIL [1] Links: ------ [1] https://webmail.westnet.com.au/index.php/mail#

Dear All, can I expose Dovecot's Manage Sieve port to the internet or should I restrict access (e.g. by IP address or VPN)? -- Christian

virtual plugin in HG unaware of namespaces
by Thomas Leuxner 17 Aug '14

17 Aug '14

The latest changes to the virtual plugin seem to have a negative effect on name space rules: $ cat dovecot-virtual * Public/* flagged While flagged messages inside the mailbox still show up, messages flagged in 'Public' are not picked up anymore. Regards Thomas

INBOX subfolders not showing up
by Matthias Sitte 16 Aug '14

16 Aug '14

Hi, I have a problem with INBOX subfolders and subscriptions which I can't solve... Maybe somebody has seen this, too... I can create regular subfolders (not in INBOX) and (un-)subscribe to them with Thunderbird. If I create subfolders in the INBOX with TB this seems to work now in v31 (just found this out), but with v24.6 neither INBOX subfolder creation nor subscriptions worked. When I modified the `subscriptions' file manually on the server, the folders would show up in TB, though. Maybe this was a TB bug, but quite similarly INBOX subfolders don't show up on iPhones (iOS up-to-date), but all other subfolders do. Any ideas what's going on?

Server dovecot: auth: Warning: sql: Ignoring changed iterate_quer
by Joseph Malloy 16 Aug '14

16 Aug '14

Hello, I am having an issue with Dovecot. I am using Roundcube to access my mailboxes, which I have set up using ViMbAdmin. However when I go to the Roundcube, I get login Failed. So looking in the mail.log I can see the following: Aug 15 13:20:09 Server dovecot: auth: Warning: sql: Ignoring changed iterate_query in /etc/dovecot/dovecot-sql.conf.ext, because userdb sql not used. (If this is intentional, set userdb_warning_disable=yes) Aug 15 13:20:11 Server dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<joe(a)anoblequest.co.uk>, method=PLAIN, rip=62.49.15.89, lip=192.168.0.90, TLS, session=<su7WCqoALAA+MQ9Z> I am most greatful for the support Joe :)

namspace management
by A. Schulze 15 Aug '14

15 Aug '14

Hello, since some weeks I'm playing with namespaces. But I still did nod found a solution for all faces of different problems. Current issue: Public namespace. I have users inbox as follow: mail_home = /data/mail/%Ln/ mail_location = maildir:~/Maildir:INDEX=~/.dovecot.index namespace { inbox = yes separator = / prefix = INBOX/ } Public namespace: namespace { location = maildir:/data/mail_public/Maildir/:INDEXPVT=~/.dovecot.index.public/ prefix = PUBLIC/ separator = / type = public } that way only one subscription file is possible. Any use could subscribe/unsubscribe any folder and that match all users. If I add "subscription=no" the parent namespace' subscription is used. In fact there is no parent namespace an no subscription management is possible at all. On the other side I tried to change the PUBLIC namespace prefix to "INBOX/PUBLIC" but now the namespace is *below* the inbox. That's also not what I want. How do other users organise the namespaces INBOX, PUBLIC, SHARED and VIRTUAL (via virtual plugin) ? Thanks Andreas

(Again) Some trouble with dovecot 2.1(.7) and SASL
by admin 15 Aug '14

15 Aug '14

The parentheses in the subject are due to referral to this discussion on the mailing list: http://dovecot.org/list/dovecot/2012-February/063851.html At first I thought I found the problem, but then realized this was 2012 and the suggested patch already is applied in dovecot. I also have segault messages in my kernel log; not too many, but it was enough to dig for it: > Wed Jun 25 08:29:05 2014 auth[17590]: segfault at 10 ip 00007f02ad5e8e56 sp 00007fff932f9250 error 4 in auth[7f02ad5d3000+40000] > Mon Jun 30 16:11:41 2014 auth[12501]: segfault at 10 ip 00007fc6a1fefe56 sp 00007fff276e6ea0 error 4 in auth[7fc6a1fda000+40000] > Sat Jul 5 13:11:32 2014 auth[15603]: segfault at 10 ip 00007f6447a6be56 sp 00007fff09c48020 error 4 in auth[7f6447a56000+40000] > Tue Jul 8 05:08:21 2014 auth[30071]: segfault at 10 ip 00007ff22656ae56 sp 00007fff26b017f0 error 4 in auth[7ff226555000+40000] > Mon Jul 21 14:25:28 2014 auth[30918]: segfault at 10 ip 00007fe1fc817e56 sp 00007fff7e654f20 error 4 in auth[7fe1fc802000+40000] <--- > Wed Aug 13 18:56:31 2014 auth[27593]: segfault at 10 ip 00007ffbf8ce8e56 sp 00007fffe0157f70 error 4 in auth[7ffbf8cd3000+40000] > Wed Aug 13 18:57:59 2014 auth[24264]: segfault at 10 ip 00007f2df31bde56 sp 00007fff094263c0 error 4 in auth[7f2df31a8000+40000] The last 2 entries are a result of me being able to reproduce the problem, the 3rd last is the only one I was able to track down (due to log rotation) I tracked the problem down to a contact form of a website of one of my customers. whenever used, the segfault gets triggered.

The used CMS is PyroCMS (v2.2.3) - the version is not up2date, but nevertheless the CMS might be the one to blame, a service should not segfault. Some packages are to be updated, as well as the CMS; but I am willing to wait to provide information, which leads to the problem, as I cannot switch between different versions on my productive system for the sake of gaining debug information. I hope that someone has any kind of clue and is willing to resolve that issue with me, asking me for the necessary information to do so. Thanks in advance!

Multiple Passdb's - Order
by Jean-Louis Dupond 15 Aug '14

15 Aug '14

Hi, Today I upgraded my dovecot to a newer version (2.2.9 debian wheezy-backports) At that moment I also reconfigured the whole thing a bit nicer. Now I stumbled on the following issue. In my configuration I use 2 backends (LDAP & passwd-file). passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n driver = static } Now this worked fine before. But if I tested it, LDAP logins worked, and passwd-file logins failed. Failed log (user is only in the passwd-file): Aug 01 21:31:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_pgsql.so Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Aug 01 21:31:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Aug 01 21:31:55 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Aug 01 21:31:55 auth: Debug: passwd-file /etc/dovecot/users: Read 10 users in 0 secs Aug 01 21:31:55 auth: Debug: auth client connected (pid=5516) Aug 01 21:31:55 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=c34kcZb/uwBbtKLu lip=xxx rip=xxxx lport=993 rport=52411 Aug 01 21:31:55 auth: Debug: client passdb out: CONT 1 Aug 01 21:31:55 auth: Debug: client in: CONT 1 xxxxx (previous base64 data may contain sensitive data) Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: ldap(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): pass search: base=uid=info(a)xxx.com,ou=mail,dc=dupie,dc=be scope=subtree filter=(&(objectClass=posixAccount)(uid=info(a)xxx.com)) fields=uid,userPassword Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: passwd-file(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): lookup: user=info(a)xxx.com file=/etc/dovecot/users Aug 01 21:31:57 auth: Debug: client passdb out: FAIL 1 user=info(a)xxx.com temp Aug 01 21:31:57 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=c34kcZb/uwBbtKLu lip=xxx rip=xxx lport=993 rport=52411 resp=xxx (previous base64 data may contain sensitive data) Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:32:01 auth: Debug: ldap(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): pass search: base=uid=info(a)xxx.com,ou=mail,dc=dupie,dc=be scope=subtree filter=(&(objectClass=posixAccount)(uid=info(a)xxx.com)) fields=uid,userPassword Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): hit: {CRAM-MD5}19192922.....

Cannot use dovecot with vpopmail and sendmail
by Matthias Fechner 15 Aug '14

15 Aug '14

Hi, I setup a configuration that will use sendmail with dovecot as imap/pop3 service and vpopmail as backend to handle virtual users and store email there. For this I created a dovecot.m4 as described in the wiki, it looks like: ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=l59DFMPhnu, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, M=51200000, U=vpopmail:vchkpw, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u Then I added to my .mc file: MAILER(dovecot) I added to my mailertable: dovecot.fechner.net dovecot:dovecot I create one entry in the virtusertable to catch a email and forward it to dovecot (all other email have to handled by another imap server till dovecot is running fine): dovecot(a)fechner.net idefix(a)dovecot.fechner.net I created a domain and a user in vpopmail to catch idefix(a)dovecot.fechner.net. If I execute: doveadm auth test idefix(a)dovecot.fechner.net Password: passdb: idefix(a)dovecot.fechner.net auth succeeded extra fields: user=idefix(a)dovecot.fechner.net So I think the first part is fine. But if I try to sent an email to dovecot(a)fechner.net I get the error message: Aug 14 21:48:34 anny dovecot: lda(idefix(a)dovecot.fechner.net): Fatal: setuid(89(vpopmail) from userdb lookup) failed with euid=1002(idefix): Operation not permitted (This binary should probably be called with process user set to 89(vpopmail) instead of 1002(idefix)) Aug 14 21:48:34 anny sendmail[94303]: s7EJXgma087740: to=<dovecot(a)fechner.net>, ctladdr=<idefix(a)anny.lostinspace.de> (1002/0), delay=00:14:52, xdelay=00:00:00, mailer=dovecot, pri=120389, relay=dovecot, dsn=4.0.0, stat=Deferred: dovecot mailer (/usr/local/libexec/dovecot/dovecot-lda) exited with EX_TEMPFAIL It seems to be a problem with dovecot-lda but I have no idea what is wrong.

Trying Dovecot Replication with dsync
by Minhas Listas 14 Aug '14

14 Aug '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ?

Quota Help
by user7743 14 Aug '14

14 Aug '14

Hi all, First post here so hopefully I get all the required information correct. I am running a mail server on Debian, its consists of Postfix (2.9.6-2), Dovecot (2.1.7) and MySQL (5.5). Basic stuff is all working find so I decided to try and implement quotas. This is working to an extent but not properly and I am a little lost so looking for some help. In my configuration the default mailbox quota is set to "*:storage=100M". When I create a mailbox with 250M specified in the database, dovecot is applying the default quota rather than that specified in the database. So in the database I have a test user with the following entry password,email,quota_kb [hash], test(a)example.org, 25000 If I turn debugging on for mail and auth I see the following logged when the user logs in (logs pasted at the end in a bid to maintain some readability) If I check the quota with doveadm I get the limit back of 102400 which is the default mailbox size rather than that from the database. doveadm quota get -u test(a)example.org Quota, name, Type, Value, Limit, % User quota, STORAGE, 19139, 102400, 18 User quota, MESSAGE, 567, - I can't quite figure out where I am going wrong in terms of getting the database value to supersede the default value set in 90-quota.conf. I did read one thing in the quota documentation on the dovecot website (http://wiki2.dovecot.org/Quota/Configuration) that I didn't get and this might be where I am going wrong but can't check. It says "Check that dovecot-lda is called with -d parameter." Where would this be configured and where could I check? Below are some other inputs - hopefully they help. ### Debug logs at login Aug 14 14:06:24: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 14 14:06:24: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 14 14:06:24: auth: Debug: auth client connected (pid=8090) Aug 14 14:06:24: auth: Debug: auth client connected (pid=8093) Aug 14 14:06:24: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=2QDLu5UAKAAuBSdf#011lip=99.99.99.99#011rip=55.55.55.55#011lport=993#011rport=50216 Aug 14 14:06:24: auth: Debug: client out: CONT#0111#011 Aug 14 14:06:24: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=ZBnLu5UAKQAuBSdf#011lip=99.99.99.99#011rip=55.55.55.55#011lport=993#011rport=50217 Aug 14 14:06:24: auth: Debug: client out: CONT#0111#011 Aug 14 14:06:24: auth: Debug: client in: CONT<hidden> Aug 14 14:06:24: auth-worker(8095): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 14 14:06:24: auth-worker(8095): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 14 14:06:24: auth-worker(8095): mysql(127.0.0.1): Connected to database mailserver Aug 14 14:06:24: auth-worker(8095): Debug: sql(test.example.org,55.55.55.55): query: SELECT email as user, password FROM users WHERE email='test.example.org';

Domain name lost for SASL
by Dominic Wong 13 Aug '14

13 Aug '14

Hi, I'm trying to set up Postfix + Dovecot (2.0.9) + PostfixAdmin on CentoOS (the standard amazon machine image) and am having problems with my SMTP user authentication. Turning on auth debugging I can see the username is losing the first part of the domain so one(a)two.three becomes one.three dovecot: auth: Debug: sql(one.three, ... ): query: SELECT username AS user,password FROM mailbox WHERE username = 'one.three' AND active='1' I don't know if it's postfix or dovecot which is trimming the username, any tips on what causes this would be greatly appreciated. Thanks

Defer email via LMTP when there is 'no space left on device' instead of rejecting it
by Christian Rohmann 12 Aug '14

12 Aug '14

Hello dovecot-users, (This problem was being discussed a little in this thread from 2011: http://www.dovecot.org/list/dovecot/2011-May/059009.html) I noticed (using LMTP) that Dovecot handles 'no space left on device' just like an 'over-quota', if I read this part of method "static int client_deliver(struct client *client, const struct mail_recipient *rcpt, struct mail *src_mail, struct mail_deliver_session *session)" "lmtp/commands.c" correctly: --- cut --- [...] else if (storage != NULL) { error = mail_storage_get_last_error(storage, &mail_error); if (mail_error == MAIL_ERROR_NOSPACE) { client_send_line(client, "%s <%s> %s", dctx.set->quota_full_tempfail ? "452 4.2.2" : "552 5.2.2", rcpt->address, error); } else { client_send_line(client, "451 4.2.0 <%s> %s", rcpt->address, error); } ret = -1; [...] --- /cut --- In consequence this means the configuration option quota_full_tempfail is applied in both cases. But to me there is a major difference between a full disk (a.k.a "admin fucked up") and over-quota (a.k.a. "user has simply too much stuff in his mailbox"). So I would like to be able tell Dovecot to reject messages due to full mailboxes, but simply defer those that cannot be stored due to a full disk (which I am to blame for). To me this should result in two separate configuration options for the two problem root-causes: quota_full_tempfail storage_full_tempfail Or did I simply miss or completely misunderstood anything here? Regards Christian

Sieve: Saving "pristine" messages for backups and spam training
by Jeff Rice 12 Aug '14

12 Aug '14

Hello, I'm trying to work out a way to have my Sieve filter save a "pristine" version of email messages as a backup, primarily to use for training the spam filter. I would like is to have every message saved into a single, site-wide directory (in the global sieve) before being processed additionally and delivered. The messages in that directory will be used to train the spam filter without having to worry about removing Spamassassin headers and so forth. I thought fileinto :copy might do what I wanted, but this creates a backup directory individually for each user. That's unmanageable for the spam training process I use. redirect *could* work, but that adds a header during the process so the email saved would not be "pristine". I'm thinking of using the extprograms plugin to pipe to a program that will do a simple copy. That feels very hackish, however, and I'm hoping there is a more elegant solution. Am I missing something obvious here? Thanks! Jeff

This seems weird, as I would expect it to be more or less randomly distributed over that interval. Does this happen at the top of each minute? If what you observe is true, the only situation I can think of that would cause this is a bunch of POP3 fetch clients running as a cron job synchronized to a minute grid (i.e seconds=0).

Options mail_nfs_storage and mail_nfs_index not in 2.2(.13) example config anymore?
by Christian Rohmann 11 Aug '14

11 Aug '14

Hey dovecot-users, did I miss anything anywhere about the configuration variables "nfs_storage" and "mail_nfs_index" being removed from the example configuration in 2.2? In 2.1 they where both in 10-mail.conf commented out and set to their default "no". But with 2.2 they are not in any of the exmaple config files anymore. doveadm is still showing the variables and they can be used as ever still. Just wondering if I missed something and this should be configured differently on 2.2 now. Regards Christian

poolmon improvements
by Timo Sirainen 11 Aug '14

11 Aug '14

I've been planning to improve poolmon failure checking for a long time already, but I still haven't managed to get to it. Maybe somebody else has more time, so here's a feature request for anyone to implement: poolmon currently gives up immediately if the first check to any service fails. It really should be trying multiple times over multiple seconds before giving up. I think ideally it would be: - Individual check timeout could still be the default 5 seconds - Add full check time setting, which could be e.g. 15 seconds. If all checks fail during this time then disable the host. - If request fails because connection gets rejected, retry quickly, e.g. after 0,1 seconds - If check fails because of protocol errors, wait for a long time, e.g. 1 second So this would avoid backend being removed in situations where it really shouldn't be removed: - Dovecot restarts - Dovecot reloads - load spikes and other random issues that cause temporary problems Especially the load spike is an annoying issue which my plan doesn't even fully solve. The solution to fix a heavily overloaded cluster isn't really to start removing all of its backends that are busy working..

Dovecot v2.2 FTS is not indexing "text/html" emails...
by Akash 09 Aug '14

09 Aug '14

Hi, I am not sure its intended or a fault in the newest Dovecot versions. I have been using Dovecot v1.2.15 on Debian squeeze and FTS is working as expected. When I search a quoted string "very good", I get 107 results including plain and HTML emails which have this phrase. In order to compare the benefits of lucene over squat, I recently started testing dovecot v2.2.13 on Debian Sid with the same maildir content. But now the same search "very good" yielded just 8 results. I thought it could be some problem with lucene so I tried switching to squat and got 107 results again. After this I deleted the old squat search index files created by v1.2.15 and re-indexed the mail-box by using doveadm index command. Now the same squat search is giving 8 results just as lucene. So I have realized that its not a problem with just lucene but FTS in newer dovecot isn't indexing those emails which have Content-type as text/html. Thus if a mail is like this: Content-Type: text/html <b>He is very good.</b> It isn't shown in search by the squat indexes created using dovecot v2.2.13. I have done further testing on some sample emails which confirmed this behavior. Why is this so? -Regards, Akash

Throttling pop3-login connections
by Alex 09 Aug '14

09 Aug '14

Hi, I have a fedora20 system with dovecot-2.2.13 running various services, including pop3. I'm noticing some users are frequently hamming pop3, and wondered if this was normal, or something I should be investigating? Aug 8 14:05:20 email dovecot: pop3-login: Login: user=<user1>, method=PLAIN, rip=97.77.115.121, lip=192.168.1.1, mpid=30509, session=<DnRtDCIAUQBhTXN5> Aug 8 14:05:21 email dovecot: pop3(user1): Disconnected: Logged out top=0/0, retr=0/0, del=0/15, size=5693601 So it is immediately followed by a logout, but when there are 50 of them successively in a five minute period, I wondered if it is creating unnecessary overhead on the system? I suppose this most likely is how they have their email client configured, but wondered if some throttling would be necessary? Any advice would be most appreciated. Thanks, Alex

postfix-dovecot via lmtp
by Timothy Murphy 08 Aug '14

08 Aug '14

I've been trying for some days to get postfix + dovecot + pigeonhole/sieve working on a CentOS-7 home server. I think I may have detected the problem; I read in /var/log/maillog Aug 4 11:29:13 alfred postfix/lmtp[14871]: 9C04C220A99: to=<tim(a)localhost.gayleard.eu>, orig_to=<tim@localhost>, relay=alfred.gayleard.eu[private/dovecot-lmtp], delay=971, delays=971/0.03/0.02/0.1, dsn=4.3.0, status=deferred (host alfred.gayleard.eu[private/dovecot-lmtp] said: 451 4.3.0 <tim(a)localhost.gayleard.eu> Internal error occurred. Refer to server log for more information. (in reply to RCPT TO command)) (I've split one long line here.) 1) I see that the permissions on /var/spool/postfix/private/ are [tim@alfred ~]$ ls -ls /var/spool/postfix/ 4 drwx------. 2 postfix root 4096 Aug 4 11:30 private The socket dovecot-lmtp setup by postfix is in this directory; does dovecot need permission to access this? 2) I see that this mail (a test email from me) was deferred. What exactly does this mean? Where is the mail stored? I couldn't find it anywhere. (It has already been brought to the server by fetchmail.) 3) Am I right in thinking that there are 2 alternatives to dovecot/sieve a) amavisd-new with postfix + spamassassin b) postfix + procmail ? 4) I remember seeing a posting (probably not in this mailing list) describing how one can trace the progress of email through the server. Unfortunately I didn't note the URL, and now cannot find it. Does anyone have a pointer to such a document? As will probably be obvious, I am not at all clear how postfix and dovecot fit together if one introduces lmtp. I take it that without lmtp (or similar) postfix just delivers email to ~/Maildir/cur (in my case), and dovecot is not involved at all until a client (KMail in my case) looks at email? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Dovecot, Thunderbird and messages in wrong folder
by Gerhard Wiesinger 08 Aug '14

08 Aug '14

Hello, Sometimes it happens that messages (e.g. one or two) appear in wrong folders in Thunderbird (latest version, also past versions, different computers, also Earlybird). When I repair the folder (folder/Settings/Repair Folder) in Thunderbird, the folder is correct then. It happens on my new server with Fedora 20, Dovecot 2.2.13 and Maildir but it also happened on my old server with Fedora 1, Dovecot 2.2.13 and mbox. Has anyone the same issue? Any guess whether it might be a thunderbird or dovecot issue? Anyone has the same issues with thunderbird and a different IMAP server (e.g. cyrus)? Thank you.

invalid/unknown path to storage
by Benjamin Connelly 08 Aug '14

08 Aug '14

Am I correct: pigeonhole now wants the symlink to the filter file to use an absolute path instead of the relative paths we had? i.e.) sieve-filterfile@ -> /home/mail/domain/user(a)domain/roundcube.sieve instead of sieve-filterfile@ -> roundcube.sieve Dovecot logs these: dovecot: managesieve(user(a)domain.org): Warning: sieve-storage: Active sieve script symlink /home/mail/domain.org/user(a)domain.org/sieve-filterfile is broken: invalid/unknown path to storage (points to roundcube.sieve). and the debug log: Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: Pigeonhole version 0.4.3 initializing Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts.

So I'm looking to make a configuration change (and then change all existing symlinks.) I just wanted to check with the list about the two settings we return as part of the user_query: concat(homedir, maildir, 'sieve-filterfile') as sieve, concat(homedir,maildir) as sieve_dir In testing it seems like changing 'sieve' to return not the whole path but just the link name, actuall causes pigeonhole to properly make the symlink with full path! Does this seem right? FreeBSD (8.4) dovecot-pigeonhole (0.4.3_1) dovecot2 (2.2.13_3) Benjamin

Pigeonhole version 0.4.3 on FreeBSD-10
by Jerry 07 Aug '14

07 Aug '14

Thu, 7 Aug 2014 06:22:01 -0400 I am running Pigeonhole version 0.4.3 on a FreeBSD 10 machine. How do I actually trace which rule in my sieve file is causing a specific action on a specific email. Other then eliminating each rule one by one and rerunning the script to isolate it, how can I discover what rule is causing the problem? Thanks! -- Jerry

Is atomic MOVING of messages between IMAP folders possible?
by Greg Sullivan 07 Aug '14

07 Aug '14

I would like to use a shared IMAP account, with multiple users accessing it simultaneously. The users would take ownership of messages by first attempting to MOVE the messages from the Inbox, into their private IMAP folder, still within the same account. Now, since there will be multiple users competing for the same messages, I naturally want only ONE of the simultaneous moves to be successful at a time. So far, this isn't working. If I do the move from two clients, simultaneously, the messages can go to *both *destination folders - duplicates can result. Is it possible to configure Dovecot and/or an IMAP client to behave the way I want it to? If the answer to this is YES, then I'll offer my config details. If the answer is NO, the next question is - do any email systems at all behave the way I want? (I tried a hosted Exchange/OWA service - it has the same problem) Thanks & regards, Greg.

Panic on alway_bcc mail with attachment while using sdbox

I do always get a panic on service lmtp, while receiving a mail by postfix through always_bcc, containing an attachment.

Important emails
by André Rodier 06 Aug '14

06 Aug '14

Hi, Sorry if I am not posting on the right mailing list, but I need email and especially IMAP experts opinion. I have developed a small perl script for Amavis that tries to recognise business emails from bulk & mailing lists, in order to promote 'important' emails, ala google. This is a feature I found very useful in corporate environments, where a lot of users are receiving advertisements, but not consider it as spam. (For info, the code is here: https://github.com/arodier/emclass) My script add an email header (X-Email-Type), and dovecot uses a virtual folder called 'Important' to present them. I know there is IMAP labels, and they are server side stored. I have successfully played with Thunderbird, but IMHO, it's not very reliable. The name of the label is the responsibility of the email client. As a result, if one client decided that $Label1 is 'Important', and $Label2 is 'Business', other clients should be configured exactly the same. I wonder if there is some norm - or convention - to attach labels to email headers, or if such a header exists, for instance a header called e.g. 'X-Tags', 'X-Keywords' or 'X-Labels'. So, once stored, an email could contains - for instance - a header like this: X-Tags: Travel,Advertisement,France. Then, it would be easy to have server side search for labels. Thanks for your feedback. Kind regards, André.

maildir: could lda/lmtp log filenames?
by A. Schulze 06 Aug '14

06 Aug '14

hello, on a mailstorage server receiving messages per lda/lmtp I like to pimp my logfile. when starting to search for a specific message I have a queueid. I like to combine that id with the filename the message has after delivery to a maildir. I know, that will not work with other formats then maildir. Aug 6 11:37:30 mailserver postfix/lmtp[17884]: 3hSnmj208Zz259d: to=<rcpt(a)example.org> relay=$lmtp-server status=sent (250 2.0.0 $dovecot-id) Aug 6 11:37:29 $lmtp-server dovecot: lmtp(1440, rcpt(a)example.org) $dovecot-id: sieve: msgid=<..>: stored mail into mailbox 'INBOX/folder' and exactly there I would like to see "stored mail into mailbox 'INBOX/folder/new/FILENAME'" yes, I know, I /should/ user doveadm and avoid access messages via filesystem but in that case it would be much faster to access the information I need. Any ideas? Andreas

Migrating from maildir to mdbox
by Felix Rubio Dalmau 05 Aug '14

Hi all, I have (I think) migrated my dovecot mail format from maildir to mdbox. I have changed in 10-mail.conf the format from maildir to mdbox, and I have executed this command for all my users: dsync -u user(a)domain.org mirror maildir:/mnt/vmail/domain/user The only output of the command has been, for some users, this: dsync(user(a)domain.org): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota Is this important? How can I check that I am effectively using the new format? Thank you, Felix

dovecot-lda 2.2.13 crashing when sieve_before used
by Christoph Lechleitner 05 Aug '14

05 Aug '14

Hi together! We use dovecot under Debian wheezy amd64, using the repository ... deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main Yesterday's routine upgrade to version 2:2.2.13-1~auto+130 (or some other upgrade that came along from Debian?) introduced a problem with mail delivery, which I was able to track down to a crash of dovecot-lda. Whenever I do something like ... /usr/lib/dovecot/dovecot-lda -d christoph.lechleitner(a)iteg.at <test.msg ... (with test.msg containing a raw e-mail message), dovecot-lda crashes. The gdb backtrace is: #0 buffer_free (_buf=_buf@entry=0x242eb20) at buffer.c:145 #1 0x00007f30d47ea4fd in array_free_i (array=0x242eb20) at /build/dovecot-8Ko2hw/dovecot-2.2.13/src/lib/array.h:108 #2 sieve_file_script_sequence_destroy (seq=0x242eb10) at sieve-file-script-sequence.c:242 #3 0x00007f30d47c963e in sieve_script_sequence_free (_seq=_seq@entry=0x7fffe2dbe900) at sieve-script.c:686 #4 0x00007f30d4a3d4b3 in lda_sieve_multiscript_get_scripts (svinst=svinst@entry=0x242abe0, label=label@entry=0x7f30d4a3e7c0 "sieve_before", location=location@entry=0x2416500 "/etc/dovecot/sieve/discard-viruses.sieve", scripts=scripts@entry=0x7fffe2dbe9b0, error_r=error_r@entry=0x7fffe2dbe998) at lda-sieve-plugin.c:271 #5 0x00007f30d4a3d7e5 in lda_sieve_find_scripts (srctx=0x7fffe2dbea40) at lda-sieve-plugin.c:740 #6 lda_sieve_deliver_mail (mdctx=<optimized out>, storage_r=0x7fffe2dbec00) at lda-sieve-plugin.c:973 #7 0x00007f30d5e05464 in mail_deliver (ctx=ctx@entry=0x7fffe2dbec70, storage_r=storage_r@entry=0x7fffe2dbec00) at mail-deliver.c:400 #8 0x0000000000402a92 in main (argc=3, argv=0x2402390) at main.c:437 The problem vanishes once I remove the sieve_before script, in our case /etc/dovecot/sieve/discard-viruses.sieve The sieve script does not contain anything fancy, and it works perfectly when used as sieve_default. It seems the mere presence of a sieve_before script triggers the problem. Some environment info: As of dovecot -n, I guess only the sieve related parts are relevant, if at all: plugin { sieve = /var/vmail/%d/%n/sieve sieve_before = /etc/dovecot/sieve/discard-viruses.sieve sieve_default = /etc/dovecot/sieve/default.sieve sieve_dir = /var/vmail/%d/%n/sieve-scripts } I also tried version 2:2.2.13-1~auto+138 from the dovecot-2.2.patched repository that I stumbled over while browsing the repository server. No difference regarding our problem. Our filesystem is ext4 disguised as simfs by the OpenVZ virtualization kernel. I'm pretty sure the filesystem does not matter with our problem. I'd be happy to re-test with testing releases, but I'd like to avoid setting up a full-blown test environment where unstable and bleeding edge versions would be ok.

Set an archive folder for every user
by Felix Rubio Dalmau 05 Aug '14

05 Aug '14

Hi everybody, I have a running postfix+dovecot installation, running flawlessly. The machine this setup is running onto has 2 mirrored SSD disks (in which dovecot stores the mails) and 2 mirrored regular HD. I'd like to keep the fresh emails in the SSD, and move them to an Archive folder after some days/weeks. Is there any way in dovecot to set up a folder for every user, that points to an external disk rather than the default one? Thank you, Felix

Old: Dovecot 1.1.18 + Squirrelmail 1.4.8 + Imapproxy New: Dovecot 2.2.10 + Squirrelmail 1.4.22 (no Imapproxy) In both, we have: [dovecot config] namespace private { separator = . prefix = Mail. inbox = yes } (The 'Mail' prefix is set this way for compatibility reasons) $imap_server_type = 'dovecot'; $default_folder_prefix = 'Mail.'; $trash_folder = 'Mail.Trash'; $sent_folder = 'Mail.Sent'; $draft_folder = 'Mail.Drafts'; $show_contain_subfolders_option = true; $default_sub_of_inbox = false; (I know some of these are redundant with $imap_server_type, but that's how it's setup now). This works as we expect with the old setup - folders are set in, e.g., $maildir/.Sent, and we only see one set of each. With the newer one, it auto-creates folders as Mail.{Trash,Sent,Drafts}, which translates into Mail.Mail.{Trash,Sent,Drafts}. If I set $foo_folder to just 'Foo' (e.g., $trash_folder = 'Trash';), the auto-creation works as expected, however, now I have two sets of folders (one indented) in the folder list, and the set linking to Mail.{Trash,Sent,Drafts} (the indented ones), don't work. What's the easiest way to get the new setup working in a way that will cause the least change (preferably no change) to end-users. TIA w

Solr indexing appends domain to users
by G H 04 Aug '14

04 Aug '14

My users are set up as "admin", "john", etc -- as opposed to john(a)example.com. When I run test command "/usr/libexec/dovecot/dovecot-lda -d admin < /tmp/mymail.txt", the mail is successfully imported with Solr, Tika (yay). However, results are never found when I search within IMAP. Why? Dovecot is appending the domain name to the user and admin fields of the Solr record ("admin(a)example.com" instead of just "admin") during index. But during searching, Dovecot is only searching for the user directly, from the Solr logs: q=body:"TESTCONTENT"&fq=%2Bbox:7dff0b0d4f84df53f25300003d823887+%2Buser:"admin" If I rerun the query via the Solr web gui with user:"admin(a)example.com", the message is found. How do I disable appending the domain name to the solr index names? Thanks, G H

I'm getting 2 errors which are probably related, the second of which I haven't actually seen an issue with yet (I just found it looking at the error log) The issue is that I cannot change my subscriptions through Thunderbird (version 31.0). I created the subscriptions through Thunderbird, but now it won't let me change them. dovecot responds with sutff like this when I sniff network traffic or configure Thunderbird to log IMAP traffic: 10 NO [NOPERM] No permission to modify subscriptions The time stamp on the .subscriptions.lock file gets updated every time I try to make a change. To test I edited .subscriptions by hand and forced Thunderbird to try to subscribe something and I got access to the folder I added, so I presume it is reading the file correctly. Permissions on~jreid/mail is 0700, the existing .subscriptions file is 0640 and .subscriptions.lock file is 0600. all the files are owned by me and their group is my primary group (not mail). As for the second error, the dovecot.index.log.newlock file gets created but no dovecot.index.log file gets created. And dovecot would have created the directory tree to those files itself... I'm new to dovecot but not Unix or IMAP so I'm sure this is just some configuration option I've missed, any help would be most appreciated. $ /opt/csw/bin/doveconf -n # 2.2.12: /etc/opt/csw/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc disable_plaintext_auth = no first_valid_uid = 100 mail_access_groups = mail mail_location = mbox:~/mail:INBOX=/var/share/mail/%u 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 { driver = pam } protocols = imap ssl_cert = </etc/opt/csw/ssl/certs/dovecot.pem ssl_key = </etc/opt/csw/ssl/private/dovecot.pem userdb { driver = passwd } $ doveadm log errors [...] Aug 03 16:47:02 imap(jreid): Error: rename(/home/jreid/mail/.subscriptions.lock, /home/jreid/mail/.subscriptions) failed: Permission denied Aug 03 16:52:49 imap(jreid): Error: rename(/home/jreid/mail/2012/.imap/Received/dovecot.index.log.newlock, /home/jreid/mail/2012/.imap/Received/dovecot.index.log) failed: Permission denied -- joe

Dovecot with dbox indexing weirdness
by Coert 04 Aug '14

04 Aug '14

Hello all, I run a local dovecot imap server, with dbox storage in my home directory. It works well, but everytime I restart the machine, it seems according to lsof to reindex everything (and I am sitting with 250k mails). Is this the intended behaviour? I would expect it to happen only once or on update of a folder? regards, Coert

autocreate mailboxes
by Mike Pultz 02 Aug '14

02 Aug '14

Hello, I just upgraded to Dovecot 2.2.13 from the 2.0 version branch- so far everything is working great. I wanted to take advantage of the mailbox option to auto create and auto subscribe users to a Sent and Trash folder (using the support for the special use flags), but ideally, I only want to do this for new mailboxes, and not for all the mailboxes that already exist on the system. The reason for this is because all the existing users likely already have a sent-mail folder configured, and I don't want to implement this, and have their sent-mail folder switched to this new one. When I set this up on my test system, I noticed that the new sent and trash folders appeared in my existing mailbox, and when I checked the account on my iPhone, it switched my sent-mail folder away from my "normal" sent-mail folder, and I couldn't change it back. Is there a way to do this ONLY when dovecot creates a new mailbox? Thanks, Mike

Advantage of LMTP
by Jerry 02 Aug '14

02 Aug '14

Sat, 2 Aug 2014 06:53:58 -0400 Presently, I have: "virtual_transport = dovecot" in my Postfix main.cf file and dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} in the master.cf file. Is there any advantage to using LMPT instead? All of my users are configured as virtual users. If I change it, do I have to eliminate the above from my master.cf file? -- Jerry

[Dovecot] Converting old emails to compressed format
by Renaud Allard 02 Aug '14

02 Aug '14

Hello, I know this question has already been asked, but I would really like a solution here as I tried all I could find on the wiki or mail archives I am now running dovecot 2.2.12 Compression works fine for new mails, so zlib works Mails are currently stored using dbox So I tried for testing dsync -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=xz" -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=" -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=" -D -v mirror -u user -m Archives maildir:~/temp dsync -o "plugin/zlib_save=xz" -D -v mirror -u user -m Archives maildir:~/temp And also converting again those maildir messages to dbox (just in case it wouldn't work from dbox format) And also with backup instead of mirror None of this actually works, mails are indeed copied, but not compressed So I am wondering if there is a way to compress those mails? Thank you

Configuring pigeonhole/sieve
by Timothy Murphy 02 Aug '14

02 Aug '14

I've been trying for a few days to get pigeonhole/sieve working in order to filter email with spamassassin. Unfortunately I have had no success; and I have found no document which simply tells me what changes I need to make to which files, and what other action I have to take. I'm running CentOS-7 on my home-server, and have postfix + dovecot working perfectly; moreover spam is marked with ***Spam*** added to the Subject header. The only problem is that this spam is getting through to my inbox. It's clear that I'm overlooking some action I should be taking, and I'm sure there must be a document somewhere that gives simple and complete instructions on setting up pigeonhole/sieve to work with SpamAssassin. If anyone knows of such a document I should be eternally grateful. I was told at one point that "You need to pass your mail through dovecot-lda or lmtp", but I have no idea what this means. I see in /var/log/dovecot when I re-start dovecot "Aug 02 00:13:04 master: Info: Dovecot v2.2.10 starting up for imap, pop3, lmtp, sieve, sieve (core dumps disabled", which seems to imply that lmtp is enabled. Any suggestions or advice gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Dovecot EE on SciLinux 6.5: No Config Files in /etc
by Asai 02 Aug '14

02 Aug '14

Greetings, I tried installing Dovecot EE on Scientific 6.5 yesterday, but there was no repo under that release version, so I hardcoded the release version to 6 in yum.repos.d/dovecot.repo. That worked, but when I installed, it didn't install any default configuration files. /etc/dovecot was empty. Is that to be expected for EE? -- --Asai

Are you implying that Dovecot 2.1.7 doesn't enable persistent modseq tracking in this case? I never claimed that earlier versions of Dovecot didn't advertise CONDSTORE or didn't implement it properly, etc. Perhaps I should have written "...after *any* of the two commands... (and maybe others)" -- meaning it does after either of those two commands, and the other ones I don't care about and so didn't test. > And as mentioned above, there are 6 different ways of enabling CONDSTORE. > (Enabling QRESYNC is done 1 way ... the "ENABLE QRESYNC" command). Yes, agreed, noted. I'm asking about two out of those five / six. And not just about what the RFC says, but about how real, out in the field, installed on mail servers that people use, possibly quite old, versions of Dovecot behave. So let me try again: Is sending SELECT ... (CONDSTORE) or STATUS (... HIGHESTMODSEQ ...) enough to enable reliable persistent modseq tracking for all versions of Dovecot which advertise CONDSTORE in their capabilities? Not what the currently relevant RFC says, but how Dovecot versions with CONDSTORE in their caps behave.

However: > Returning NOMODSEQ on mailboxes that don't support persistent > mod-sequences has worked since 1.2.0, at least as far as I know. The linked message from 2012, discussing 2.0.18, says: "2) If a mailbox doesn't have modseqs enabled, return NOMODSEQ. This isn't ideal, but seems like the only possibility" And based on my tests, Dovecot 2.1.7 returns "HIGHESTMODSEQ 1" for mailboxes where modseq tracking has not been enabled. You're largely right about the value only being relevant if the client enabled CONDSTORE, and I don't care too much about this quirk, just wanted to to get a clarification on this as well, if possible.

Differences in "Delivered-To" header between deliver and LMTP
by Jeff Rice 01 Aug '14

01 Aug '14

Hi, I'm transitioning my server over from using the deliver LDA and LMTP. Suddenly a bunch of sieve filters stopped working, and I noticed the contents of the Delivered-To header are different. Using Dovecot's deliver LDA, the contents are a bare email address (foo(a)bar.com) Using Dovecot LMTP, they are in brackets (<foo(a)bar.com>). Is there a reason why this isn't consistent between the two delivery agents? It seems like it ought to be. Jeff

solr_add_definite_query quotes queries
by G H 01 Aug '14

01 Aug '14

So Solr 4.0 and higher supports regular expressions in searching. However, Dovecot is quoting search queries in solr_add_definite_query (via solr_add_str_arg). This breaks regex searching. I do a sample search for emails with "merged" in their body via the query /merg.*/. If you look at the Solr logs, it is sending: q=body:"/merg.*/" which is converted to body:\"/merg.*/\" inside Solr. but if it had sent only: q=body:/merg.*/ then regex would have worked. Is regular expression searching on the dashboard? I'm considering patching fts-backend-solr.c to not quote-enclose the search, but am looking for any better suggestions. Or perhaps not quote-enclose if the search is prefixed with RX: (ie: "RX:/merg.*/")... Thanks, G H

Does anyone have a Solr 4+ compatible schema.xml for dovecot indexing? I am trying to test to see if regex-based FTS searching works through IMAP, but Solr 4.9.0 is throwing an error, "SolrException: undefined field text", on startup with the schema.xml included with Dovecot 2.2.9. Thanks. G H

Issue with exim and auth protocol
by Mildred Ki'Lya 31 Jul '14

31 Jul '14

Hi, I'm trying to set up exim (4.83) as a submission server, and need to set up the dovecot authentication in exim. I'm having an issue with that (documented at <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756258>) The problem is that exim doesn't follow the handshake as described here: <http://wiki2.dovecot.org/Design/AuthProtocol>. The wiki page says that the client should start the handshake, but exim waits for the server to start and to receive the DONE command until it starts its own handshake. What I actually get is: exim connects to dovecot auth dovecot VERSION 1 1 dovecot SPID 48 And then, dovecot stops (I presume it waits for the client handshake, VERSION and CPID). Exim on its side waits for the DONE. This results in the SMTP connection by exim never replying to the AUTH PLAIN command. This is exim 4.80 (or 4.83) and dovecot 2.1.7. I have another server set up almost exactly the same (but with dovecot 2.1.17) where it does work. In that case, dovecot finishes the handshake before exim starts its handshake. It results in: exim connects to dovecot auth dovecot VERSION 1 1 dovecot MECH PLAIN plaintext dovecot SPID 10905 dovecot CUID 1 dovecot COOKIE d3861d29441f06d962490eab8549fd46 dovecot DONE exim VERSION 1 0 exim CPID 10619 exim AUTH 1 PLAIN service=smtp secured rip=82.247.184.53 lip=80.67.179.36 nologin resp=<base64 encoded string> I don't understand what could change the dovecot behaviour in that regard. Is there a solution that would only require modifying the configuration? Thank you, Mildred

PAM and YubiKeys
by Jack 29 Jul '14

29 Jul '14

Hi List, I am trying to get authentication to Dovecot with a Yubikey OTP. I have the PAM modules installed and can successfully authenticate to ssh with the Yubikey, so I am confident that the network level and Yubikey configuration is correct. I can also authenticate to Dovecot via PAM using a plain password, however when I try to use the Yubikey authentication with Dovecot things don't go well. Network monitoring reveals that the software does not even attempt to connect to the authentication servers. My Dovecot authentication is configured as follows :- passdb { driver = pam args = failure_show_msg=yes dovecot override_fields = proxy host=1.2.3.4 master=XXXXXX pass=XXXXXX } userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users } The dovecot Pam config file is :- auth sufficient pam_yubico.so id=99999 key="xxxxxxxxxxx" authfile=/etc/yubikey_mappings debug @include common-auth @include common-account @include common-session When failing to authenticate with Dovecot, the PAM debug log shows :- [../pam_yubico.c:parse_cfg(761)] called.

identify MUA connecting?
by Juan Pablo 29 Jul '14

29 Jul '14

Hello I am using dovecot 1.2.15 on ubuntu. Is it possible to somehow log the MUA information that is connecting to Dovecot? The reason I am wanting to do this is I would like to know if people are getting their email on personal devices instead of work secured / standardized phones.

Missing IMAP Subfolders
by Tim 29 Jul '14

29 Jul '14

I've recently encountered an issue with my IMAP folders on Dovecot 2.0.19. When I telnet into my account and perform a list, I get the following response: A list "" "*" * LIST (\Unmarked) "." "INBOX" A OK List completed. However I know there are subfolders here and have examined the server directly via SSH and strangely: a select INBOX.Clients * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1394028715] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest a OK [READ-WRITE] Select completed. When I also subscribe to a couple if these which I am able to to do despite not being able to "LIST" them, I get this with LIST-EXTENDED: a04 LIST (SUBSCRIBED RECURSIVEMATCH) "*" "*" * LIST (\Subscribed \NonExistent) "." "INBOX" (CHILDINFO ("SUBSCRIBED")) * LIST (\Subscribed \NonExistent) "." "INBOX.Clients" (CHILDINFO ("SUBSCRIBED")) * LIST (\Subscribed \NonExistent) "." "INBOX.Clients.Bob" a04 OK List completed. Just not sure why a LIST is not giving me a full list as it's causing problems subscribing to these with Mail Clients. Any help is appreciated!

incremental mailbox syncs for quick migration
by Jogi Hofmüller 29 Jul '14

29 Jul '14

Hi all, We are facing quite large mailboxes (>10GB) in our migration from cyrus to dovecot. I did a test on one mailbox and repeated the sync a couple of times with the expected result that the second, third, etc. sync took only seconds compared to minutes for the first sync. We use this command to sync a mailbox: doveadm backup -R -u USER imapc: Are there any problems to be expected when we first do a sync for all mailboxes but do not migrate the users right away but instead do the actual migration using a second sync? Cheers, -- j.hofmüller http://thesix.mur.at/

problem migrating shared folders from cyrus to dovecot
by Jogi Hofmüller 29 Jul '14

29 Jul '14

Hi all, We face a problem migrating shared mailboxes from an old cyrus server to dovecot. Whereas migrating regular users works like a charm, the shared mailboxes cannot be migrated. dsync/doveadm states: "Error: Failed to access mailbox INBOX: Mailbox does not exist". This is somehow true since the shared mailboxes live not under user.mailbox but rather under shared.mailbox (cyrus special). Has anyone a solution for this peculiar problem? Cheers, -- j.hofmüller http://thesix.mur.at/

Multiple servers and NFS
by Richard Hector 29 Jul '14

29 Jul '14

Hi all, For some reason, I didn't go to http://wiki2.dovecot.org/NFS until now, and I'm starting to get worried ... The plan was to have multple servers (MXes) receiving mail, and delivering via LMTP to multiple backend dovecot servers (with amavis in front of dovecot; LMTP both sides). Then we'd have multiple servers for clients to use IMAP or POP3. This is more or less how the system already works, except with Courier IMAP, and postfix on the backends, delivering to maildirs with procmail. But with the recommendation to use the Director for both IMAP/POP3 and LMTP - that starts to sound like I need a whole bunch more servers to run Directors and proxies, and even then it might not be a good idea to have different servers running lmtp and imap/pop. One possible mitigating point is that our 'load balancing' is DNS round-robin, so a given client will probably stick with a single imap/pop server anyway, but if the user has multiple clients (desktop/mobile etc) then they may still hit different servers. Can someone clarify best practice for a setup needing multiple servers for load balancing and redundancy? Is Courier already likely to have been suffering these problems? Oh, the NFS server is a NetApp Filer, if that matters. I'm using dovecot 2.2.9 from debian wheezy backports, in order to get the quota policy daemon support. Thanks, Richard

Dovecot mailstore performance tuning
by Murray Trainer 29 Jul '14

29 Jul '14

HI All, We have a couple of dovecot director proxies and six backed mailstores each accessing mailboxes stored on five NFSv4 filsystems with about 1TB of mail on each in maildir format. We have about 800 max users on each mailstore at peak times and performance appears to starting to degrade at these times. The mailstores are pretty recent hardware with 64GB of RAM and 24 cores. The NFS storage is EMC VNX and we are doing about 250 I/O per sec upto max of 500 on each filesystem. I need to squeeze more performance out of these servers whether that is in the NFS client, Dovecot or Linux OS/kernel areas. We use LDAP for auth and I am doing some tuning in that area. The NFS filesystems are mounted with the options below: 10.11.0.238:/mailbox_store_01 on /home1 type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,nordirplus,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.11.0.96,local_lock=none,addr=10.11.0.238) My dovecot config is below. I am not seeing any obvious issues in the server logs. Any suggestions on how to improve performance would be appreciated.

No, this is a dovecot server running in my own laptop. I guess some computer crash left the mail in an inconsistent state, and I need to assert the extend of the problem.

Segfault dovecot 2.2.9
by Simon Gareste 29 Jul '14

29 Jul '14

Hi all, When trying to set up dovecot, I somehow managed to get a segfault. Trying to launch dovecot from command line (simply execute 'dovecot') results in the error message: Segmentation fault (core dumped) Trying dovecot -n results in pretty much the same: # 2.2.9: /etc/dovecot/dovecot.conf Segmentation fault (core dumped) Looking at syslog, I see doveconf[3676]: segfault at 200 ip 00007fbb93c4fcb3 sp 00007fff005b4c10 error 4 in libc-2.19.so[7fbb93c04000+1bc000] I tried but couldn't find the core dump anywhere on the server. Any help on this would be appreciated too. I (trying to ) run it with postfix, on an Ubuntu 14.04 (Linux mail2.arturia.com 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux), brand new server. What troubles me even more is that I just set up successfully another mail server a week ago, with the same configuration (diffing the conf folders) except for log or mailbox paths (driver and stuff are the same). In the google search I've done, I saw some stuff about openssl: both servers are running 1.0.1f, since one is running fine, I guess this is not the culprit. One difference I noticed between the two servers is that on the failing one, there is no /var/run/dovecot. I presume this folder and its files are created once dovecot is launched, so that's why it's not present, and is only a symptom of the failure, not a cause? Thanks for your help, and please tell me what other information I could provide to help. Simon

Multiple passwords with sql authentication
by BlackVoid 29 Jul '14

29 Jul '14

I'm currently working on a control panel which is using postfix, dovecot and other applications and I want to add application specific passwords to increase security. I found one solution [1], however it requires the password to be included in the query which is something I do not want to do, because the query may be written in clear-text to log-files. So I'm wondering if there is a way to have multiple passwords with dovecot without risking passwords being leakied in clear-text to log-files.

Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 28 Jul '14

28 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system. Unfortunately I can't get dsync to do that. Using a config that specifies only one namespace allows me to convert either mboxes or Maildirs to mdboxes but not both.

ACLs on Top level mailboxes.
by Dan Carroll 28 Jul '14

28 Jul '14

Hello, I’m in the process of migrating a mail server to new hardware. At the same time, I’ve made the decision to switch from courier to dovecot (v2.2.13) and from what I have seen so far I’m pretty happy. I have two questions for the list. I’d like my users mailboxes (Maildir format) to look like this: Inbox UserCreatedSubFolder1 UserCreatedSubFolder2 … Sent UserCreatedSubFolder3 Drafts Trash Junk Archives The Top level folders (Sent, Drafts etc) are all “Special” and I do not wish the users to be able to delete them. I also don’t want them to create new Top level folders. This will force all custom folders to be under a Top Level folder. The Maildir format currently looks like this: ~/Maildir/cur ~/Maildir/new ~/Maildir/tmp ~/Maildir/.INBOX/.UserCreatedSubFolder1/cur ~/Maildir/.INBOX/.UserCreatedSubFolder1/new ~/Maildir/.INBOX/.UserCreatedSubFolder1/tmp ~/Maildir/.Sent/cur ~/Maildir/.Sent/new ~/Maildir/.Sent/tmp etc…. I can get ACLs working with dovecot-acl files, and the permission I need (I think is) “owner lrwstipe”. But if I put it into the ~/Maildir directory, then it applies to Inbox. I’ve tried creating an .INBOX dir and putting it in there but that did not work. I also tried some global-acl file settings but I could not make that work either. Basically, I’m wondering how to apply ACLs to the Top level and have different ACLs for the actual inbox when using this scheme. I’m not opposed to changing the Maildir format, but that would mean a lot of work re-doing proemial scripts. My second question relates to migration. Is it enough that I copy the Maildir structure and simply delete the courier files or is it a lot better to use a courier->dovecot migration tool? I realise folder subscriptions would be lost but that’s OK, I’ll recreate them manually anyway. Thanks for your time. -Dan

After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character on a Linux system
by David Davidov 28 Jul '14

28 Jul '14

We have following issue: After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character. This was not possible with our previous version 2.1. Tested. Our Dovecot runs on Debian Wheezy system. According http://wiki2.dovecot.org/Plugins/Listescape this should be disabled on a Posix system. We use the usual separator '.' as you can see in the config file later. Issue can be reproduced using outlook 2013. On the file system this is the representation of the "Family/Friends" folder /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/new /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/tmp /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/cur Doveadm does not lists properly the folder doveadm mailbox list -usteve(a)alltimes.com |grep -i Family INBOX.Family This is the server configuration: ----------------------- dovecot -n # 2.2.13: /dovecot/etc/dovecot/dovecot.conf # OS: Linux 3.2.59-grsec x86_64 Debian 7.6 auth_username_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890@!#$&\'*+=?^_`{|}~.-" base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pid=%p %c mail_access_groups = vchkpw mail_fsync = never mail_plugins = quota stats namespace { inbox = yes location = maildir:~/Maildir:INDEX=/home/vpopmail/dovecot-indexes/%d/%n prefix = INBOX. separator = . type = private } passdb { args = /home/vpopmail/bin/chkpw driver = checkpassword } plugin { acl = vfile:/dovecot/acls quota = maildir quota_rule = INBOX.Trash:ignore stats_command_min_time = 1 mins stats_domain_min_time = 12 hours stats_ip_min_time = 12 hours stats_memory_limit = 64 M stats_refresh = 30 secs stats_session_min_time = 15 mins stats_track_cmds = yes stats_user_min_time = 1 hours } protocols = imap pop3 service imap-login { executable = /dovecot/libexec/dovecot/imap-login inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } process_min_avail = 16 service_count = 0 } service imap { executable = /dovecot/libexec/dovecot/imap-ld-hack process_limit = 1500 vsz_limit = 256 M } service pop3-login { process_min_avail = 16 service_count = 0 } service pop3 { executable = /dovecot/libexec/dovecot/pop3-ld-hack process_limit = 1500 vsz_limit = 256 M } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } ssl_ca = </apache/conf/ssl.crt/server-ca.crt ssl_cert = </apache/conf/ssl.crt/server.crt ssl_cipher_list = ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP ssl_key = </apache/conf/ssl.key/server.key userdb { driver = vpopmail } userdb { driver = prefetch } protocol imap { imap_client_workarounds = mail_max_userip_connections = 100 mail_plugins = quota stats acl imap_quota imap_stats } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota stats acl pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = yes pop3_no_flag_updates = yes pop3_uidl_format = %f } ----------------------- We need a way to prevent creation of those folders, because our users create several of them a day. Any suggestions? regards, David Davidov

mdbox "doveadm purge" strategy
by Jesus Cea 28 Jul '14

28 Jul '14

Hi there. I am using mdbox storage with great success but I am seeing something I find strange and I would like to compare notes with you. When doing "doveadm purge", "m.*" files with non deleted messages are left alone, but "m.*" files with deleted messages copy the "non deleted" messages to a newly created "m.*" file and delete the original. Good so far. What surprises me is that the newly created "m.*" files are not fullsize. they can be "small" files, not using the 2MB max size I have configured for mdbox storage. Moreover, those files stay in that size forever, no new messages are appended ever. I guess each old "m.*" file with deleted messages generates a new independent "m.*" containing only the non deleted messages. I wonder if that is the case and if that is a fundamental issue that can't be changed. I would like my "m.*" files to use the full configured mdbox size, instead of having quite a few of new SMALL "m.*" files. Thanks for your time and attention!. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

struggling with pigeonhole date extensions
by Laeeth Isharc 27 Jul '14

27 Jul '14

I am struggling with how to use the date extension for Dovecot/Pigenhole implementation of Sieve email filtering language. I have read RFC 5260 several times and tried different things with no luck. I would like to place all messages this year up till the end of March into the specified mail folder. What the snippet below actually seems to do is take any messages this year (whether before or after March). Any thoughts? if allof(date :value "eq" :originalzone "date" "year" "2014", date :value "le" :originalzone "date" "month" "3") { fileinto "INBOX/2014 up to Mar"; stop; } Incidentally, it's puzzling how sparse the ecosystem seems to be for managing sieve scripts given the importance of email and the unmanageability of volumes these days without rules. What would be nice to have is something like the Outlook rule manager as a front end and server side sieve scripts on the back. I looked at Modoboa (which seems to be the only standalone option), but it's a bit heavy for my taste and I struggled to configure it in the time I had available. Thanks in advance.

IMAP forward boxes
by Andre Dietrich 26 Jul '14

26 Jul '14

Hi all, since a few weeks I'm experimenting with some "IMAP forward boxes", but I didn't find a satisfactory solution yet. Target function is a directory structure like following in a shared mailbox: /intern/users/fred /intern/users/ted /intern/users/alice The idea is, that a mail, moved to the directory "/intern/users/fred" via IMAP-client will be forwarded to "fred(a)test.domain" without modifying the mail (except the header line "delivered to:"). So if you get a mail in your inbox and want fred to answer it, you drag'n'drop it to /intern/users/fred. Fred gets the mail in his inbox and can answer it. To share all inboxes, to drop mails directly to them, is not an option, because I don't want everybody to see all other inboxes mails. Only to apply "-w-" ACL rights isn't an option either, because it seems to irritate the mail clients. Some month ago I had a partially working solution using a cron bash script. The script read the mails in the cur and new folders, processed the folders path and passed it to sendmail. It's ok, but it has to run quite often to get an adequate forwarding time and on sendmail errors mails got lost without any notification. It would be nice to have a dot-forward file in this subfolder (like in the qmail mailbox root), which is processed by dovecot when a mail is dropped in. Is it possible to solve this with a sieve script, a dot-forward file, or something similar ? I'm grateful for all solutions / ideas ! thx! Andre

Hi, Yesterday, I committed two important and rather big changes to the Pigeonhole repository. The first creates a generic interface for implementing Sieve script storages. It was already possible to some extent to read Sieve scripts from other sources than the local filesystem, such as Dovecot dict, but that was still pretty limited, as it was not possible to do this with sieve_before/sieve_after. This is now supported. But, more importantly, ManageSieve did not support storing Sieve scripts on locations other than the local filesystem. Now, alternatives can be implemented. Still, I haven't actually implemented write access to a storage other than the local filesystem yet, but now this would be much easier to achieve. The second creates an LDAP script storage implementation. Much like the dict storage, it is still read-only. It can be compiled directly into the Sieve interpreter, and, alternatively, it can also be compiled as a plugin called sieve_storage_ldap. I've updated the documentation in the sources. For all Xi repository users: I added compilation of LDAP storage as a plugin. Read the INSTALL files and other files referenced therein for more information about how to use the plugin. The plugin is installed as part of the dovecot-ldap package. This is a rather big change, but it should all be backwards compatible in terms of configuration. If you have problems (I heard about one so far), please don't hesitate to notify me. Regards, Stephan.

Maildir migration - using separate INDEX and CONTROL directories?
by Richard Hector 24 Jul '14

24 Jul '14

Hi all, I'm working on a migration from Courier to Dovecot, and the courier-dovecot-migrate.pl seems to work ok, but it puts all the metadata files (dovecot-uidlist etc) in the Maildir, while I want to put them in the appropriate places as specified: mail_location = maildir:~/Maildir:INDEX=/var/mail/meta/index/%d/%1n/%1.1n/%n:CONTROL=/var/mail/meta/control/%d/%1n/%1.1n/%n http://wiki2.dovecot.org/Quota/FS explains why some of these files need to go in different places (which is why I'm doing it), but I haven't seen a complete list of what files will be moved as a result of those directives. Is there a handy tool to move the files to the right places? Or is there a complete list of what files need to go where? Thanks, Richard

Sieve plugin (fc17 + sendmail + roundcube)
by Franck CALLEJA 24 Jul '14

24 Jul '14

Hello, I'm trying to configure sieve plugin on my mail server so that people can do mail filtering (and mostly vacation notification) on their account. The mail server is running fine since 5 years and is based on :- sendmail- dovecot- roundcube It serves 2 differents domains. I've recently installed pigeonhole for fc17, and managed to configure managesieve plugin in roundcube successfully. Users can now manage filters from roundcube. The problem is that filters are not applied when new mails arrives. I've modified dovecot.conf to activate sieve plugin, and the configuration is as follow : # dovecot -n# 2.1.16: /etc/dovecot/dovecot.conf# OS: Linux 3.8.13-100.fc17.x86_64 x86_64 Fedora release 17 (Beefy Miracle) log_path = /var/log/dovecot.logmail_debug = yesmail_location = mbox:~/mail:INBOX=/var/spool/mail/%umanagesieve_notify_capability = mailtomanagesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihavembox_write_locks = fcntlnamespace 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 { driver = pam}plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve}protocols = imap pop3 lmtp sieveservice imap-login { service_count = 0}service lmtp { executable = lmtp -L}service pop3-login { service_count = 0}ssl_cert = </etc/pki/dovecot/certs/dovecot.pemssl_key = </etc/pki/dovecot/private/dovecot.pemuserdb { driver = passwd}protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log mail_plugins = " sieve"}protocol lda { mail_plugins = " sieve"} In /etc/sendmail.cf I've this configured :# cat /etc/mail/sendmail.mc divert(-1)dnl include(`/usr/share/sendmail-cf/m4/cf.m4')dnl VERSIONID(`setup for linux')dnl OSTYPE(`linux')dnl define(`confLOG_LEVEL', `15')dnl define(`confDEF_USER_ID', ``8:12'')dnl define(`confTO_CONNECT', `5m')dnl define(`confTRY_NULL_MX_LIST', `True')dnl define(`confDONT_PROBE_INTERFACES', `True')dnl define(`PROCMAIL_MAILER_PATH', `/usr/bin/procmail')dnl define(`ALIAS_FILE', `/etc/aliases')dnl define(`STATUS_FILE', `/var/log/mail/statistics')dnl define(`UUCP_MAILER_MAX', `2000000')dnl define(`confUSERDB_SPEC', `/etc/mail/userdb.db')dnl define(`confPRIVACY_FLAGS', `authwarnings,novrfy,noexpn,restrictqrun')dnl define(`confAUTH_OPTIONS', `A')dnl define(`confMIN_QUEUE_AGE', `15m')dnl define(`confTO_QUEUERETURN', `5m')dnl define(`confMAX_MESSAGE_SIZE', `15000000')dnl define(`confDONT_BLAME_SENDMAIL', `forwardfileingroupwritabledirpath,ForwardFileInUnsafeDirPath,ForwardFileInUnsafeDirPathSafe')dnl define(`confTO_IDENT', `0')dnlFEATURE(`no_default_msa', `dnl')dnl FEATURE(`smrsh', `/usr/sbin/smrsh')dnl FEATURE(`mailertable', `hash -o /etc/mail/mailertable.db')dnl FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable.db')dnl FEATURE(`genericstable',`hash -o /etc/mail/genericstable.db')dnlGENERICS_DOMAIN_FILE(`/etc/mail/generics-domains')dnlFEATURE(redirect)dnl FEATURE(always_add_domain)dnl FEATURE(use_cw_file) FEATURE(use_ct_file)dnl FEATURE(local_procmail, `', `procmail -t -Y -a $h -d $u')dnl FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access.db')dnl FEATURE(`blacklist_recipients')dnlEXPOSED_USER(`root')dnl DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnlFEATURE(`accept_unresolvable_domains')dnl FEATURE(`relay_hosts_only')dnl FEATURE(`dnsbl', `ipwhois.rfc-ignorant.org',`"550 Mail from " $&{client_addr} " refused.

Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 24 Jul '14

24 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system. Unfortunately I can't get dsync to do that. Using a config that specifies only one namespace allows me to convert either mboxes or Maildirs to mdboxes but not both. Using the above config dsync somehow thinks the source and destination are the same: Syncing mailbox for user nima (136 MB) Setup done. doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib20_zlib_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so doveadm(nima): Debug: Effective uid=5224, gid=1162, home=/home/nima doveadm(nima): Debug: Namespace mboxes: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=no, \ list=yes, subscriptions=yes location=mbox:~/Mail/MBox:INBOX=/var/mail/nima doveadm(nima): Debug: fs: root=/home/nima/Mail/MBox, index=, control=, inbox=/var/mail/nima, alt= doveadm(nima): Debug: Namespace maildirs: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, \ subscriptions=yes location=maildir:~/Mail/Maildir doveadm(nima): Debug: maildir++: root=/home/nima/Mail/Maildir, index=, control=, inbox=, alt= dsync(nima): Debug: Effective uid=5224, gid=1162, home=/home/nima dsync(nima): Debug: Namespace mboxes: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=no, list=yes, \ subscriptions=yes location=mdbox:/scratch/mail-convert/nima dsync(nima): Debug: fs: root=/scratch/mail-convert/nima, index=, control=, inbox=, alt= dsync(nima): Debug: Namespace #mbox/: Using permissions from /scratch/mail-convert/nima: mode=0700 gid=-1 dsync(nima): Debug: Namespace maildirs: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, \ subscriptions=yes location=maildir:~/Mail/Maildir dsync(nima): Debug: maildir++: root=/home/nima/Mail/Maildir, index=, control=, inbox=, alt= dsync(nima): Fatal: Both source and destination mail_location points to same directory: /home/nima/Mail/Maildir What am I doing wrong?

doveconf option "-e"
by Django [BOfH] 24 Jul '14

24 Jul '14

Hi Timo, If I could tell you a little smart wish, I've one for you. ;) Today I'm writing my own configurationdocumentation 'bout Dovecot in my dokuwiki and for documentation purposes I changing some options several times a day. Postfix supports on its own postconf an option -e. So I can set up mostly every configuration-option on the fly. Dovecot's doveconf has no such option. So, I changed the configuration-files and reload my dovecot-daemon. It were grait if doveconf has a similar function, like postconf's option "-e". Maybe you can make a little update to doveconf in one of the upcomming releases? ;) Best regards Django -- "Bonnie & Clyde der Postmaster-Szene!" approved by Postfix-God http://wetterstation-pliening.info http://dokuwiki.nausch.org http://wiki.piratenpartei.de/Benutzer:Django

Problems with custom plugin
by Lukas Mika 24 Jul '14

24 Jul '14

Hi everybody, I wrote a plugin for Dovecot 2.1.something which was based on the information found at http://wiki2.dovecot.org/Design/Storage/Plugins and by studying the mail_log plugin. My plugin can be found here: https://github.com/dim-0/dovecot-mbc It takes the notify plugin's information, that a new mailbox has been created (or an old one been renamed) in order to trigger a custom script (which in my case sets default ACLs for shared mailboxes). This plugin went quite well for a while, but then I recently upgraded Dovecot to version 2.2.9 and now I cannot build my plugin anymore. I get two error messages which both describe the same thing: src/mbc-plugin.c: In function ‘mbc_mailbox_create’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) src/mbc-plugin.c: In function ‘mbc_mail_user_created’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) Obviously the module context nowadays expects another attribute/struct named "reg". However, I cannot find any information about this within the documentation and plugin mentioned above. The only clue I have got yet is the definition in module-context.h: union STRUCT_NAME_module_context { struct STRUCT_NAME_module_register *reg; // it's allowed to have some structure here so it won't waste space. // for example: struct STRUCT_NAME_vfuncs super; }; However, I still cannot make any sense of it (yet). Could you please help me in filling the gap and understanding, what has to be changed? Thanks a lot in advance for an awesome piece of software and any input on this topic, Lukas

FTS lucene indexer-worker segfaulting

Hi, I've just set up fts-lucene and when I run searches on my inbox or when I run the indexer (`doveadm index INBOX`) I get the following segfault. I've run it multiple times and noticed that the data value is different each time so I guess it doesn't always crash at the same point. I'm running dovecot 2.2.13-1 with clucene 2.3.3.4-8 on Arch Linux.

Dovecot GMail API
by Timo Sirainen 23 Jul '14

23 Jul '14

Hi all, I'm still (mostly) on vacation this week and afterwards lots of different things to do .. But hopefully I'll still get around to answering all the pending mails in this list and applying some of the patches people have sent and get the next v2.2.14 release out. Anyway, people have kept asking about GMail API and Inbox App and how that affects Dovecot. For a while now I've been planning on implementing some kind of a HTTP API for mail access, so might as well use GMail's: http://www.dovecot.fi/dovecot-launches-a-gmail-api-compatible-rest-api-to-e…

SSL certificate problem (SSL alert number 42)
by Boyandin Konstantin 23 Jul '14

23 Jul '14

Hello, After client (Thunderbird, now version 31.0) updated today, it stopped connecting to Dovecot IMAP4S. The infamous "SSL alert number 42" is reported. Mail server uses local (created for intranet) CA certificate as root. I would appreciate pieces of advice on how to handle that without enabling plaintext authentication over insecure channels. Other intranet services work with this local CA quite fine. Thank you in advance.

[patch] enable ECDH auto functions based on feature defines, not on version number
by Hanno Böck 22 Jul '14

22 Jul '14

Hello, I recently tried to build my system with libressl instead of openssl. In dovecot one issue that popped up was that libressl doesn't have the ECDH auto functions from openssl 1.0.2 beta versions. However as the #ifdef's in dovecot's code check for the openssl version and libressl's version numbers are higher the compilation fails there. Attached is a patch that will change that checks. Instead of checking for the version number it checks for the availability of the feature itself (by checking for the define of SSL_CTRL_SET_ECDH_AUTO). This should make this check more robust and work independently of the version number of the used openssl instance. cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

BUG: Authentication client sent unknown handshake command
by Lukas Haase 22 Jul '14

22 Jul '14

Hi, Some time ago my dovecot started to become BUGgy: Evertime I restart the system, dovecot is started but I cannot login. I see the following information in the logs: Jul 4 04:04:36 mail dovecot: auth: passwd-file(user,127.11.91.218,<nfkQjFT9vwCADFra>): no passwd file: /etc/dovecot/imap.passwd Jul 4 04:04:36 mail dovecot: auth: Error: BUG: Authentication client sent unknown handshake command: REQUEST?1183186945?20438?1?a8c7241e7b0778f9f0125da760cd16fa Jul 4 04:04:36 mail dovecot: imap: Error: Authentication server didn't send valid SPID as expected: MECH#011PLAIN#011plaintext Jul 4 04:04:36 mail dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=20438 client-id=1) Jul 4 04:04:36 mail dovecot: imap-login: Internal login failure (pid=20438 id=1) (internal failure, 1 succesful auths): user=<user>, method=PLAIN, rip=127.11.91.218, lip=73.82.101.172, mpid=20439, TLS, session=<nfkQjFT9vwCADFra> It does not help to restart the client. But when I then restart the server service dovecot restart it works again. But this is very dangerous because the server might reboot and I might not immideately have the chance to restart dovecot manually.

subfolders in public mailboxes
by Burak Arslan 21 Jul '14

21 Jul '14

Hello, I added this to the configuration: namespace { type = public separator = . prefix = public. location = maildir:/var/mail/public subscriptions = no list = yes } and I can list maildirs inside these folders correctly. however, I can't see any subfolders. The issue seems to be that /var/mail/public dir itself is interpreted as a maildir directory. However, what I'd like to do is to have a bunch of directories inside /var/mail/public and treat them as separate maildirs. (I'd like to use this to make a few existing mailboxes public) is this possible? Best regards, Burak

Dovecot Replication: First Run
by Asai 19 Jul '14

19 Jul '14

Greetings, I'm working on building a redundant Dovecot server which will be replicated with my original. I would like to know if there's any potential problems I could run into in running this for the first time. For example, during an initial sync is it possible for the new server to sync improperly with the original and delete all of the emails on the original? Are there any gotchas that I should be aware of when doing a first run? -- --Asai

Difference btw. Dovecot Director and Dovecot Proxy
by Nathan Schultheiss 19 Jul '14

19 Jul '14

Hello, For a few days I try to understand what program (Dovecot Director or Dovecot Proxy) I should use for my email architecture. We are a hospital, and for security reasons, we must host ourselves our emails, and we must leave Google Apps... I wish to make a Dovecot backend for each department of the hospital. Each backend Dovecot has a local storage. Server 01: cardiology Server 02: emergency ... Server 05: administration Dovecot looks in the database which server to use to store email (lmtp) and transfer the mail for storage. I do not understand if I have to work with Dovecot Director or Proxy if I would that LMTP or IMAP request are forwarded to the right backend. Each have self storage and have not access to the other backend storage (no nfs, no network storage, ...). Users indicate imap.hospital.local, this point to Dovecot Director or Proxy and Dovecot check the login/password and forward the user to the right backend. In my database I put user@hospital = storage host 172.16.2.10 = folder /home/vmail/user/ (Maildir) I've read that the Director can refer the user to the same backend when there is a activ session (POP, IMAP, LMTP) But can we tell him to always refer the user to the same backend (IMAP and LMTP) ? I've found this picture schema who user have Dovecot Proxy => Dovecot Director => Dovecot Backend And I'm confused why they have proxy + director ?!? Can anyone tell me if I need to focus on Dovecot Director or Dovecot Proxy to create the architecture of this hospital ? My question is probably stupid for Dovecot sysadmin, but I'm lost in the WIKI :) Thanks in advance, Nathan

Postfix user@domain splitting
by Ricardo Branco 18 Jul '14

18 Jul '14

I have been trying looking though all the wiki documents to setup LMTP. It now seems to all be connected except that it keeps saying that the user is not recognised when postfix sends to LMTP, it sends the full recipent email address but seems that on the dovecot side it is unable to work with this. I have checked the userdb and made sure its using %n but alas it still does not work. Currently ive had to revert to using LDA as it works fine with that but i still dont know how as the postfix config variable $RECIPIENT is the full email address and does not seem to matter to LDA.

Does anybody is experiencing the same errors? cheers Giovanni

Dovecot/K9/Thunderbird IMAP interaction issues: replicated messages, constant reloading (TB) & missing new messages (K-9)
by David Gessel 18 Jul '14

18 Jul '14

Version Info: FreeBSD 9.2-RELEASE #0 r266046 AMD64, Dovecot 2.2.13, dovecot-pigeonhole-0.4.3, amavisd-new-2.8.0_2,1, clamav-0.98.4, postfix29-2.9.9_1,1, postfixadmin-2.3.6, spamassassin-3.4.0_12 (zpool data and output of dovecot -n at bottom of post) I suspect these are related problems and further that they are related to some trivial newb error I've made in my configuration, but searching descriptions of the symptoms has not yet guided me to a solution. I recently migrated from Courier to Dovecot on new hardware and imap synced a 16GB mailstore (du -hs) divided up into annual directories with about 15,000 messages each. I mention the size because it seems an errant Remove Duplicate Messages (Alternate) 0.3.9 acting on what seem to be false duplicates in Thunderbird reduced the inbox size from 7500-ish messages to 1300 (DOH!) and may have solved my K-9 problem described below. My old Courier server still has the vast majority of these messages and I will resync someday and then try to file them away more expediently than my previously somewhat lazy management style to keep the inbox small. * In thunderbird, I get constant downloading of messages. Every time I switch to the inbox from another folder, the messages start redownloading. This sometimes, but not always, seems to create duplicate messages, but I'm now fairly sure they are only created in the client and not on the server. Searching through various forums, it appears this has been a problem for Thunderbird for some time, but it wasn't for me on Courier. As posts about similar errors seem to have petered out over the last year without any clear guidance on how to fix it that I could find, I expect there's a simple fix I just haven't found yet, either in TB configuration or in Dovecot. Any hints? I tried Thunderfix to remove the .msf files and will be redownloading my mail over the thin pipe out to Iraq for the next 6 months (DOH!). One artifact is that when I restart thunderbird, my inbox is reported as having about 130 messages in it, then thunderbird starts redownloading headers and eventually gets back up to the 1297 currently listed both in the TB pane and by ls | wc -l in /cur. Is it possible there is a time out that needs to be extended? In TB, I've set (among other less apparently relevant options) mailnews.tcptimeout;1000 mail.db.idle_limit;30000000 * Also, with Thunderbird, I get duplication of messages in the client. I suspect this is related to the previous redownload error, but there is some indication in some posts that it is potentially related to a dirty flag. I've had this problem before with Thunderbird and Courier, but it went away after a TB update. It seems to have reappeared with Dovecot. The TB client hasn't been updated during the transition, so some interaction issue seems more likely than a pure TB bug. Likely TB's fault as this is a well known, but poorly diagnosed TB issue (deleting duplicates regularly seems to be the solution, but my inbox would double in size every few hours on the LAN. Now that I'm remote over a 2mbps link, it has slowed way down: bonus!). * "Expunged message reappeared, giving a new UID" errors appear a lot. This might well be related to the last error. This seems to happen with TB client connections, but I'm not sure what action triggers it. I am not replicating. I tried renaming 10-director.conf to 10-director.conf.disabled and got no complaints from Dovecot (as I'm not using replication, it shouldn't) but that indicates that this Expunged message reappeared error is probably of a different source than, for example, Simon Fraser's debug effort. * K9 was only showing a subset of my messages and generally not the new ones. They'd appear in the alert properly, but weren't visible in the client and sometimes they'd be visible and then disappear later. I imagined there could a correlation between TB checking mail and perhaps moving messages from /new to /cur and K9 losing track, but the potentially tragic "duplicate" removal may have reduced my inbox to a size that k9 can handle as K9 inbox display seems normal now as far as I can tell. When I resync (assuming I can), I sort of dread this problem reappearing. K9 worked as expected against Courier with the same inbox. These apparently difficult to diagnose problems are occasionally suggested as related to namespace configuration issues and thunderbird is reported to have issues with some separator options. I vaguely suspect this, but I'm pretty sure my namespace config is default and should be well tested. I haven't, for example, explicitly stated the default "/" but left it commented out. I increased the connection limit count per user*IP to 20 as TB seems to be parallel downloading a lot of folders. This has neither improved nor degraded performance in any way I can see and is probably irrelevant. Any hints greatly appreciated.

Sieve: adding Date: header when missing
by Daniele Nicolodi 17 Jul '14

17 Jul '14

Hello, there is a way with a sieve rule to add a Date: header when it is missing? Adding one with the time of reception of the message or using the date from the the first Received: header would be good options. Unfortunately I'm receiving some useful automated messages that lack a Date header and this screws up the sorting in my imap clients. I have a script to fix those acting on the Maildir storage, but I would prefer to have the thing solved more radically. Thanks. Cheers, Daniele

If local Dovecot stops working, check lo
by Steve Litt 17 Jul '14

17 Jul '14

Hi all, You probably know this already, but just in case... Let's say you have your email client getting mail from a Dovecot server on the same computer (which is a really good way of doing things, by the way). Then one day your email client starts saying "connection refused" after a suitably long timeout. So then, to find out where things are getting stuck, you do the following command: openssl s_client -connect 127.0.0.1:993 -quiet And you don't even get an OK back. This means it's not your username or password, because you never even got that far. Before spending a lot of time doing diagnostic tests and narrowing it to the root cause, try this as root: ifdown lo ifup lo A malfunctioning lo will cause Dovecot not to connect to clients. My experience with Debian Wheezy is that lo "goes down" a lot, so this is one of the first things I do when odd stuff happens.

Resource Temporarily Unavailable on replicator-doveadm
by Cassidy Larson 16 Jul '14

16 Jul '14

We're running 2.2.13 on two servers with replication. Still trying to get my replication tweaked correctly and I’m noticing a bunch of these errors for the same users over and over again: dsync-server(user(a)host.com): Error: write(/var/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable The 5-7 that I see all have quite a number of individual mailboxes (20+), I’m wondering if that has something to do with it? Also, my replicator status for full resync requests has been hovering around 2300-2400 the last few days: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 2410 Waiting 'failed' requests 1 Total number of known users 9836 In checking the replication status for some of the “Resource temporarily unavailable” list from above, if I run it multiple times it outputs different results for the fast and full sync time: # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:21 49:43:34 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:55 00:10:55 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:56 00:10:56 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:57 00:10:57 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:24 49:43:37 - doveconf output for the replicator service is: service replicator { process_limit = 10 process_min_avail = 2 unix_listener replicator-doveadm { group = mailsys mode = 0666 user = mailsys } unix_listener replicator { group = mailsys mode = 0666 user = mailsys } } Anybody have any clues or suggestions? I’d be much appreciative. Thanks, Cassidy

Dovecot 2.2.13 Assertion failed in mailbox_list_create
by Potapov Sergey 16 Jul '14

Hi All, I have noticed that dovecot / exim on Cpanels appear to support sending emails via exim after authenticating to Dovecot - see message below 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message We are migrating users mail off cpanels into split mta and dovecot servers and are having problems with some users being abble to send emails afterwards. Does anyone understand how the CPanel config works? Thanks Murray

Dovecot2 Antispam MAILTRAIN backend with SpamAssassin
by Mohammad S. Babaei 15 Jul '14

Hi there, I've already asked this question on FreeBSD forums without getting any response. So, I thought it's a good idea to ask it again here. I've setup Dovecote2 (2.2.13) + Postfix + SpamAssassin on my FreeBSD 10 VPS and it works flawlessly. Though, I couldn't setup the Dovecot Antispam plugin to train SpamAssassin when I move mails to the Junk folder.

Permissions with mailman

Hi, I'm running a Mailserver, and recently also a Mailinglist. I'm sporting # dovecot --version 2.1.7 on a debian stable machine with postfix & mailman. Everything works fine, except that no archive is being created (here an excerpt from my log): Jul 2 15:29:39 blade01 postfix/qmgr[5217]: B30BCE1F52: from=<list(a)mail.myserver.com>, size=802, nrcpt=1 (queue active) Jul 2 15:29:39 blade01 dovecot: lda(list): Error: user list: Initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/mail/vmail//list/mail) failed: Permission denied (euid=38(list) egid=38(list) missing +w perm: /var/mail/vmail/, we're not in group 5000(vmail), dir owned by 5000:5000 mode=0775) Jul 2 15:29:39 blade01 dovecot: lda(list): Fatal: Invalid user settings.

Now: $ groups list list : list vmail and the permissions are 775, but it's still complaining about "missing +w perm". What is it referring to with "we're not in group 5000"?

Changed IMAP MOVE behavior in Dovecot 2.2.x
by Iavor Stoev 15 Jul '14

15 Jul '14

Hello, After the migration to Dovecot 2.2.13 from Dovecot 2.1.17, I noticed a changed behavior when I move a message from one folder to another. I use Thunderbird with: Account Settings -> Server Settings -> When I delete a message: Just mark it as deleted. I use Thunderbird 24.6.0 with IMAP. With Dovecot 2.1.x when I move a message, the message appears in the new folder and is marked for deletion in the original folder (which gives me an easy option to undo the action if I made a mistake until I choose to Compact/Purge the folder). With Dovecot 2.2.x when I move the a message it is marked for deletion and is AUTO Compacted/Purged immediately. Is there a way to achieve the 2.1.x behavior with Dovecot 2.2.x? Thank you Iavor

Integrity check of mailboxes before dsync
by Murray Trainer 15 Jul '14

15 Jul '14

Hi All, I am migrating a large number of Dovecot mailboxes - some of them are quite old. I hit an issue yesterday with a corrupt file (index?) that was preventing the mailbox from being synced properly As soon as I removed the file the dsync worked. Is there a way to check the integrity of each mailbox / indexes before I dsync it? Thanks Murray

director / main instance
by Will Yardley 15 Jul '14

15 Jul '14

I have directors and backend servers running on the same systems (x3). To be able to run doveadm foo with a minimum of fuss (without having to list socket paths explicitly), should it be the director that's the "default"? If so, is it safe to symlink '/var/run/dovecot' to '/var/run/dovecot-director', or should I just make the director's base path /var/run/dovecot directly? in dovecot-director.conf, I have: service doveadm { inet_listener { port = 8889 } } local 192.168.x.0/24 { doveadm_password = Foo } doveadm_proxy_port = 8888 and in dovecot-main.conf, I have: service doveadm { inet_listener { port = 8888 } } local 192.168.x.0/24 { doveadm_password = Foo } protocol doveadm { auth_socket_path = director-userdb } Is this correct (and is there anything unneeded / redundant there)? # dovecot instance list path name last used running /var/run/dovecot-director director 2014-07-14 20:36:49 yes /var/run/dovecot-main main 2014-07-14 20:36:49 yes # dovecot director status mail server ip vhosts users 192.168.x.xx 100 2 192.168.x.xx 100 0 192.168.x.xx 100 0

Transition from one server to another.
by Anders Wegge Keller 15 Jul '14

15 Jul '14

A frind of mine and I are running a dedicated server, that among other things host mail for ourselves and friends and families. All in all about 15 different domains with 35-40 users. The machine in question is old, so we are doing a slow transition from the old server to the new one. So far, we've managed to move web hosts seamlessly. Due to the technical capabilities at some of the user base, it would be nice to get to a setup, where we can move individual users imaps from the old server to the new one, as we get the time to visit them. I have an idea how such a transition could go: 1. Upgrade the old dovecot 1.2.15 to 2.1.whateveritis from debian squeeze backports. 2. Set dsync up to replicate mails from the old server to the new server. I know that 2.2 is recommended, but with a limited amount of user, I'm willing to take a performance hit. 3. Migrate my parents &c to use the new server. 4. When all users have been moved on to using the new server, upgrade MX records for the domain to point at the new server. 5. When all MX records are updated, decalre success. Is this feasible, and what would the risks be. For instance, during step 4, mails are bound to arrive at bothe the old and new server for some time. Will this cause problems? Is there a simpler solution to the problem? -- /Wegge Leder efter redundant peering af dk.*,linux.debian.*

protocol specific AuthDatabase Queries
by claus 14 Jul '14

14 Jul '14

Hi, i have to configure different sql-queries for protocol lmtp, another for protocol smtp and one query for other protocols. I have configured in "/etc/dovecot/conf.d/auth-sql.conf.ext" one entry for all protocols and 2 protocol specific entries: protocol lmtp { passdb { driver = sql args = /etc/dovecot/dovecot-lmtp-sql.conf.ext } } protocol smtp { passdb { driver = sql args = /etc/dovecot/dovecot-smtp-sql.conf.ext } } passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } is this correct or do i have to configure all possible protocols seperately? First i had a working configuration for all protocols except for lmtp (but now i need additionally a special query for smtp): protocol !lmtp { .. } protocol lmtp { .. } Can you tell me whats the prefered configuration? Thanks Claus

doveadm dump ignores .pvt
by Thomas Herrmann 14 Jul '14

14 Jul '14

While debugging a different problem, I used "doveadm dump" to show information about a maildir folder; it happily reported values from dovecot.index and dovecot.index.log (confirmed by strace): [...] messages count ........... = 978 seen messages count ...... = 967 [...] However, mail clients reported different values, I guess because the Seen flags were actually stored in the dovecot.index.pvt.log files. Is this a known problem or a result of my (maybe unsupported?) setup? My public maildir folder contains only links to mailboxes of the private maildir of the mail admin, i.e.: /home/vmail/public/.Info -> ../adwin.de/mail-admin/Maildir/.Info namespace { list = children location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/adwin.de/%n/public prefix = ADwin/ separator = / subscriptions = no type = public } My setups leads to .pvt-files in the public namespace, could this be a problem? http://wiki2.dovecot.org/SharedMailboxes/Symlinks explicitly states that symlinking _should_ work. Using version 2.2.13 (debian packages). Regards, Thomas

Flags in public folders disappear when more than 25 flags are used
by Thomas Herrmann 14 Jul '14

14 Jul '14

Hello, I have been using flags in public folders for quite a while with no problems. Once the flags were added to all clients (Thunderbird), they were visible and synchronized properly. Now I have added some new flags, and in the dovecot-keywords files I see that I am now using more than 25 flags (in which case they are not stored using an additional letter in the filename). Now I see that newly added flags are only visible in the client for a short time and then suddenly disappear. How can I debug this, or what may be a reason for this?

High user number tune
by Edwardo Garcia 13 Jul '14

13 Jul '14

Halo, This might seem like another indirect thread. I Monday started new job, first task must replace courier. The job use POP3. and IMAP only for webmail, but must server support 4K POP3 at one times. I see from similar thread current settings not adequate , we will use TLS and if wiki read right Iprotocol So am close in think that need ? service pop3-login { process_limit = 4096 } service pop3 { process_limit = 4096 } service imap-login { process_limit = 2048 } service imap { process_limit = 2048 } then we have service managesieve { process_limit = 1024 } is that all we need change? I see in other thread someone says service anvil but I can not find out about it, does need change as well ? Why is it so complicated to change to let more user on, most other change one setting, dovecot want dozen :(

Pigeonhole sieve misfile
by Patrick Domack 13 Jul '14

13 Jul '14

I'm having an issue with sieve putting some emails into the spam folder, that should not be matching the spam rule. I tried looking but can't seem to find a debug option. Is there any way I can get a log of what the sieve rule path that matches so I can locate the misfiring rule? or maybe something else that is going on. I already checked the dovecot sieve log file, and there is nothing in there.

macros
by Arkadiusz Miśkiewicz 13 Jul '14

13 Jul '14

Does dovecot support any form of macros? I would like to share configuration file between several servers. Configs are different only in tiny aspects. Somethine like: dovecot-server.conf (different on each server): %define ID 55 %define SOMETHING SELECT FROM * WHERE something %define MECHANISMS digest-md5 dovecot-main.conf (common, shared config) !include dovecot-server.conf user_query = ${SOMETHING} AND id=${ID} auth_mechanisms = plain login ${MECHANISMS} etc -- Arkadiusz Miśkiewicz, arekm / maven.pl

Replication on dovecot 2.0
by Tom Barber(Alabs) 11 Jul '14

11 Jul '14

Hi Guys I'm running an Ubuntu 12.04 LTS server and not being particually inclined to upgrade I'm wondering what options I have for replication as it appears to be running dovecot 2.0.19. I saw the wiki page about replication and whilst it says you should use 2.2+ it doesn't say what the minimum requirements are, so I tried doing what it says but I get: Fatal: Plugin 'replication' not found from directory /usr/lib/dovecot/modules Any ideas or tips. Thanks Tom

1.2.4 disk full errors
by Iain Hallam 11 Jul '14

11 Jul '14

Hi. A user on a rather old mail system we have filled their disk space, and Dovecot has started to give lots of errors in the logs about "Expunged message reappeared" and "Duplicate file entry". The user can only see a few new messages, not the 33,551 in their inbox. In the TODO file in the current source code[1], Timo notes that (line 147): maildir: out-of-disk-space failures apparently cause all kinds of problems, e.g. "Expunged message reappeared", "Duplicate file entry"? [1] http://hg.dovecot.org/dovecot-2.2/file/c55c660d6e9d/TODO Does anyone know what's happening with Dovecot here and how to recover so that this user can see mail again? Unforuntately we're on a very old version, 1.2.4. Though there is a plan for migrating to a newer platform, I need to get this user accessing email again rather more urgently. Thanks, Iain Hallam.

dovecot lda invalid user settings
by CJ Keist 10 Jul '14

10 Jul '14

I'm now dealing with issue with some users on mbox getting invalid user settings in /var/adm/messages. /var/log/syslog has: Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.error] lda(ejames): Error: user ejames: Initialization failed: Namespace '': Mail storage autodetection failed with home=/top/academic/Atmos/people/ejames/home Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.crit] lda(ejames): Fatal: Invalid user settings.

Trigger for using an sqlite dictionary for quota
by David Anderson 10 Jul '14

10 Jul '14

Hi, I'm using Dovecot 2.0.9, and was trying to set up a dictionary process to use an sqlite database for quota management. The wiki page has examples for MySQL and PostgreSQL: http://wiki2.dovecot.org/Quota/Dict For sqlite, a trigger needs to be created to get it to work. But I was not sufficiently skilled in sqlite to adapt the PostgreSQL trigger (given on the above URL) for use. Nor did Googling find any example of anyone else who had done it. Does anyone here have an example, or the ability? (Through Googling I found an example trigger for using sqlite with expiries - but I was looking at quotas).

HIGHESTMODSEQ tracking
by Kostya Vasilyev 10 Jul '14

10 Jul '14

Hello, I'd like to follow up on someone else's old thread: http://dovecot.org/list/dovecot/2012-April/082624.html I understand that Dovecot (that 2012 discussion was about version 2.0.18) can return "HIGHESTMODSEQ 1" upon SELECT if persistent modseq tracking was never enabled for a mailbox. I'd like to get a clarification on how to enable proper persistent modseq tracking. Per RFC 4551, "A client supporting CONDSTORE.... indicates its willingness to receive mod-sequence updates... by issuing:" SELECT mailbox (CONDSTORE) STATUS (... HIGHESTMODSEQ ...) ... others ... It seems that Dovecot 2.1.7 (Debian 7.5) enables persistent modseq tracking after one of the above two commands (and maybe others). So far so good. So my questions are: 1 - Is this (enabling persistent modseq) also the case for all Dovecot versions prior to 2.1.7 that advertise CONDSTORE? There must be people running older versions out there, older than 2.1.7. If not, how can I branch my logic to not use HIGHESTMODSEQ, given that Dovecot doesn't appear to return any version info via its greeting or via the ID command? 2 - Is persistent modseq tracking (assuming it's been enabled) available for all types of backend mailbox formats that Dovecot might be using? To be more specific, can it ever be the case that Dovecot appears to enable modseq tracking, returning nice looking HIGHESTMODSEQ values from SELECT / STATUS, but the actual values get reset or not get updated because they're not properly persistent? I'm excluding changes to UIDVALIDITY here, obviously when that changes, the entire mailbox state must be assumed to have changed completely. 3 - I guess the change to return NOMOSEQ instead of "1" for mailboxes with modseq tracking disabled, as mentioned in that discussion from 2012, never happened? At least on the 2.1 branch? Thanks, -- K

Multiple email clients not in sync
by Marc Perkel 09 Jul '14

09 Jul '14

Hello everyone, I'm not sure if this is an issue with dovecot or my various email clients, or my settings. I'm running 2.2.13 and I have Thunderbird on my desktop and K@mail on my android phone. In theory if I delete email on one it should delete it on the other. It does delete it on the server - but the other client isn't always "aware" of it. Same thing sometimes with read messages. I read on one device but the other didn't know it's read unless I shut down and restart the app. Not knowing the details of how this all works I'm assuming there is some form of notification that goes on in the background so as to let other clients know what other clients do so they can sync up. And that where my setup isn't working consistently. Maybe my expectations are just too high? Maybe I don't have things set up correctly? What am I missing? Thanks in advance.

Problem with virtual mailbox when using K9 mail (android)
by Henrik Kjölhede 08 Jul '14

08 Jul '14

Hi! I've managed to setup a virtual mailbox that shows all unread or flagged mail from a selection of IMAP folders. This works great with Roundcube, which I use as webmail client. However, using K9 mail on my android phone, a mail that is opened seems to be immediately marked as read, and any flagging I do doesn't take. Presumably this is because it can't be reached any longer in the virtual folder. I tried adding the recent flag to the virtual search line, but that doesn't make any difference. I haven't been able to locate any information about anyone else experiencing this problem, so I was hoping that someone here could help. I realise that this is not exactly a "dovecot problem", but perhaps someone here has found a solution that they are willing to share. The search line in dovecot-virtual is currently "OR RECENT (OR UNSEEN FLAGGED). Regards

Limit confusion
by Micah Anderson 08 Jul '14

08 Jul '14

Hi, On one of my dovecot servers, i've got a limit problem... and I'm a little confused about which knobs I should adjust to solve it. I've been getting both of these: Error: net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailableess This one caused me to go read that wiki page, but none of those seem to apply to me: . i'm running 2.2.9 . i dont have service imap { client_limit }, although I do have service auth ( client_limit = 1024 } . my dovecot/auth process shows: dovecot/auth [91 wait, 0 passdb, 0 userdb] . it doesn't appear the master process is using very much cpu (in fact the system is mostly low load in general) . I have service_count = 0 set for imap-login for the 'high performance mode' dovecot: master: Warning: service(imap): process_limit (2560) reached, client connections are being dropped The second is because I have process_limit of 2560 for the imap service... I can raise that to 4096, but I suspect there are other limits I need to juggle? Thanks a lot for any suggestions!

Dovecot ignores existing mailboxes and creates its own
by Martin Vegter 08 Jul '14

08 Jul '14

Hello, I have Postfix with Maildir format. User's emails are being delivered into $HOME/mail/inbox Apart from ~/mail/inbox, there are the usual folders: $HOME/mail/archive $HOME/mail/drafts $HOME/mail/inbox $HOME/mail/trash Now I have installed dovecot, and set mail_location = maildir:~/mail:LAYOUT=fs additionally, I have defined mailboxes as follows: namespace inbox { mailbox drafts { special_use = \Drafts } mailbox sent { special_use = \Sent } mailbox trash { special_use = \Trash } } The problem I am having is following: 1) dovecot ignores the folders (drafts, sent, trash) and creates its own folders begining with capiotal letter: Drafts Sent Trash 2) dovecot ignores ~/mail/inbox and instead creates ~/mail/cur ~/mail/new ~/mail/tmp can somebody please advise how to tell dovecot, to use my existing folder structure, ie: ~/mail/inbox/{cur,new,tmp} ~/mail/drafts/{cur,new,tmp} ~/mail/sent/{cur,new,tmp} ~/mail/trash/{cur,new,tmp} any advice would be much appreciated thanks, Martin

Redis sentinel support in dict
by Lazy 08 Jul '14

08 Jul '14

Redis sentinel ( http://redis.io/topics/sentinel ) is a service that monitors and manages redis master slave replication. Using sentinel you can easily create a redis ha cluster. You can connect to a sentiniel and subscribe to certain events then in case of an failover update the redis address to new master etc. I think this is better suited to be used with dict proxy. Do You think it can be implemented without changes to dovecot core ? -- Michal Grzedzicki

We just upgraded from 2.1.16 to 2.2.13. One user is experiencing problems when using the shared namespace. Specifically it happens when opening/reading a message and when deleting messages. These functions work for other users. So far, this appears to be only affecting one user. The shared folder is a local ext4 file system and utilizes acls # 2.2.13: /private/dovecot/etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (15360) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (10243) # OS: Linux 2.6.32-358.11.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.5 (Santiago) default_process_limit = 5120 first_valid_uid = 100 listen = * mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/a2/imap-index/%u mail_plugins = quota acl namespace { hidden = yes inbox = no list = children location = maildir:/a1/dove-shared:INDEX=/a2/imap-index/dove-shared/%u prefix = sharedimap/ separator = / type = shared } 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 = /private/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } passdb { args = scheme=CRYPT username_format=%u /private/dovecot/etc/passwd driver = passwd-file } plugin { acl = vfile quota = fs:INBOX:mount=/a1 quota2 = fs:Home quota:mount=%h } protocols = imap lmtp service imap-login { service_count = 1 } service imap { process_limit = 2048 } ssl_cert = </private/ssl/certs/mail.engr.oregonstate.edu.pem ssl_key = </private/ssl/certs/mail.engr.oregonstate.edu.pem userdb { args = /private/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = username_format=%u /private/dovecot/etc/passwd driver = passwd-file } protocol imap { mail_max_userip_connections = 20 } Here's the backtrace in gdb.

Multiple Instances with Director
by Cassidy Larson 08 Jul '14

08 Jul '14

I have four front end servers with two backend servers. Each front end server has three instances for different mail hosts (individual SSL certs, etc). I'm looking at adding a fourth instance on each front end server for the director process. Currently we just return the backend server ip via SQL and use the old master username/password to proxy the inbound POP/IMAP sessions to the correct backend server. The plan is for each instance to have connect to the same list of director_servers (one from each front end server). What's the trick to separate a director instance into its own setup and having multiple instances/servers connect to that director? Currently I have on my proxy instance: director_servers = 10.128.1.42:9090 (this is the inet_listener from the director instance) service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } unix_listener director-userdb { mode = 0600 } } And I get in logs: director: Fatal: No inet_listeners defined for director service (for standalone keep director_servers empty) Do I need an inet_listener on the front end instance if I want to forward all director queries to the director_servers list? Or is there some other trick to get a proxy front end to talk to a separate director instance(s)? Thanks, Cassidy

question on lmtp logged message
by Leonardo Rodrigues 07 Jul '14

07 Jul '14

Hi, I have dovecot running for IMAP4/POP3 and also local delivery through LMTP. It's working just fine, absolutely no problem on that, setup is fine. Anyway, sometimes LMTP seems to not be able to deliver some messages and keep them on postfixqueue. And on the next or third try, the message gets delivered successfully. The logged message, however, is not helping me identify what is happening.Example: (error - message was expunged) Jun 25 11:49:39 correio postfix/lmtp[21835]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], conn_use=6, delay=13, delays=0.07/0/0/13, dsn=4.2.0, status=deferred (host correio.domain.com.br[private/dovecot-lmtp] said: 451 4.2.0 <vanilson.parreira(a)domain.com.br> Message was expunged (received-date) (in reply to end of DATA command)) (successfull delivery) Jun 25 12:34:42 correio postfix/lmtp[6411]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], delay=2716, delays=2714/0/0/2.3, dsn=2.0.0, status=sent (250 2.0.0 <vanilson.parreira(a)domain.com.br> U7pOLAHsqlPvMgAAHvf8vg Saved) During these two log entries, absolutely nothing was changed, no configuration, absolutely nothing. Everything is local, i mean, no NFS involved. So, finally, question is: what does the 'message was expunged' message given from LMTP means ??? This is happening quite often but, as i mentionted, sooner or later all messages are getting delivered. It's working despite the delay this is causing.

dbox alternate storage and samba
by Francesco 07 Jul '14

07 Jul '14

Hello everyone, i was just wondering if it's possible to use a samba share as an alternate storage for dbox format. I tried creating a samba share, but when i try to move the email to the alternate storage using doveadm altmove, no errors are printed but no mails are moved. Everything works if the alternate storage is simply another directory on the server hard drive. am i mssing something? thanks in advance.

rmdir() EBUSY warnings on 2.2.12
by Giel van Schijndel 07 Jul '14

07 Jul '14

Hi, I'm getting a lot of syslog spam on FreeBSD 10 from nfs_flush_file_handle_cache_dir where, apparently it tries to rmdir() the mountpoint of my mail storage. > Jul 4 00:04:44 mailhost dovecot: imap(user(a)example.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail/vhosts/example.com) failed: Device busy We're using ZFS and have /var, /var/mail, /var/mail/vhosts, /var/mail/vhosts/example.com and /var/mail/vhosts/example.com/user as separate ZFS datasets (to enable per-user and per-domain snapshotting). So apart from NFS flushing being unnecessary (ZFS != NFS) I'm not really sure why using rmdir() for another directory than the Maildir specified in mail_location is a good idea. I.e. given that Maildirs shouldn't ever be emtpy (cur,new,tmp) anyway. -- Met vriendelijke groet, With kind regards, Giel van Schijndel -- > A programmer started to cuss > Because getting to sleep was a fuss > As he lay there in bed Looping 'round in his head > was: while(!asleep()) sheep++; > -- piercings -- http://bash.org/?845468

[help]how to refresh pigeonhole sieve vacation days data
by wuwei 07 Jul '14

07 Jul '14

hello everybody: I'm using dovecot with pigeonhole sieve Plugin.everything goes well.but when i use vacation module,i found a problem: I write a sieve with a vacation module in, and put it to the sieve location ,used *PUTSCRIPT* comand with *ManageSieve* and *set it ACTIVE*.It's work!I use A email send mail to him and receive an auto-reply.then ,I modify the sieve only change the days num from 7 to 1.Then I use B email send mail to him and receive an auto-reply too. The next day,I send two mails too.But only B receive the auto-reply.I thought that I would receive two mails too. so i think that A email's data in sieve maybe still 7 days.Then I restart the dovecot,but the problem still exsit. Is anyone know how to refresh the data or is their anyother way to solve the problem? thank you! -- View this message in context: http://dovecot.2317879.n4.nabble.com/help-how-to-refresh-pigeonhole-sieve-v… Sent from the Dovecot mailing list archive at Nabble.com.

If like from Nick Edwards suggested a imapproxy is used it will. imapproxy is keeping the connection open. doveadm who will give you a list of all actual logged in users. Without imapproxy you are right: Every page reload will cause a login and a logoff. I get some webmail users by "accident". To get an overview how many users used roudcube within a period check the database table users/last_login. Andreas

Disable user login for a few seconds ?
by Florent B 05 Jul '14

05 Jul '14

Hi all, I need to move e-mail files of my users from one file system to another. I use a MySQL backend on Dovecot 2.1. How can I do to disable temporary an account while moving files ? I have an "active" bit in my DB, but if I set it to 0, my MX servers are bouncing mails. How can I do to disable temporary an account ? In fact, I need dovecot not to do any change on files... I think I could change account password for a while, and reset it after migration, but it will disturb connected users. Maybe I could chmod 0 files on my old file system during migration ? How Dovecot will act ? Thank you :) Flo

Shared Mailbox + LDAP Easy with this script
by Allan Cassaro 05 Jul '14

05 Jul '14

Hello guys, After some hours fighting with shared mailbox, I finally understand how it works - and, realy, I can't believe how easy it is! So, to help others like me and to improve the shared mailbox with Dovecot this script does all the "hard work". I don't know if this group permit attachments, so, let's the link: https://sites.google.com/site/allancassaro/mkshared.tar.gz Enjoy! ===== From README file ===== This is a simple code to help with Dovecot Public Shared Mailbox function. Just configure a public shared mailbox with ACLs, change the configuration file and run this program. How it works: 1) The program connect to the LDAP server and fetch groups from it (with ldap filter) 2) With groups, it fetches the members and owners (or any attribute you want); 3) It will walk into the "shared folder" folder base directory and: 3.1) Rename any directory that was renamed in LDAP (based on entryUUID ldap attribute); 3.2) Create diretories and skeletion (new, cur and tmp) of any group that exists in LDAP; 3.3) Optionaly, remove any "orphan" directory (wihtout a ldap entrey); Example: dn: cn=Everyone,ou=Shared_Mailbox, dc=example,dc=com objectClass: labeledURIObject objectClass: top objectClass: groupOfURLs cn: Everyone labeledURI: ldap:///ou=Users,dc=example,dc=com?uid?one?(objectClass=person) member: uid=user2,ou=users,dc=example,dc=com member: uid=user3,ou=users,dc=example,dc=com member: uid=user1,ou=users,dc=example,dc=com member: uid=user.surname,ou=users,dc=example,dc=com owner: uid=user4,ou=Users,dc=example,dc=com This will create a folder tree like this: /path/toshared/.Everyone /path/toshared/.Everyone/new /path/toshared/.Everyone/cur /path/toshared/.Everyone/tmp With permission file (/path/toshared/.Everyone/dovecot-acl): user=user1 lr ... user=user.surname lr user=user4 lrwstipekxa Hope this helps you!

Shared folders not listed by IMAP
by Bambero 04 Jul '14

04 Jul '14

Hello I just upgraded my system and there is a problem with shared mailboxes. When I use the doveadm command I can see shared folders: doveadm mailbox list -u 'test(a)mydomain.pl' Drafts Sent Spam Trash Shared Virtuals Virtuals/all Shared/test2(a)mydomain.pl Shared/test2(a)mydomain.pl/Sent INBOX But I can't see them over IMAP protocol. Some config opts: valid_chroot_dirs = /var/mail mail_chroot = /var/mail namespace { type = shared separator = / prefix = Shared/%%u/ location = maildir:/%%u/Maildir:INDEX=~/Maildir/Shared/%%u subscriptions = yes list = yes } plugin { acl = vfile:cache_secs=5 } plugin { acl_shared_dict = file:/var/mail/%i.db } protocol imap { mail_plugins = $mail_plugins imap_quota imap_acl imap_zlib } My version of dovecot is 2.2.10.

[Dovecot] dovecot: disable ssl compression
by Andreas Schulze 04 Jul '14

04 Jul '14

Hello, Our "it-security" department asked me about Qualys warnings like -> SSL/TLS Compression Algorithm Information Leakage Vulnerability As far as I learned it's compression inside ssl. postfix-2.11 knows 'tls_ssl_options = no_compression' ( see http://www.postfix.org/postconf.5.html#tls_ssl_options ) is the something comparable in dovecot too? Looks like most extensions in ssl exist only to be disabled :-/ Thanks Andreas

mixing Maildir and mdbox
by gustavo panizzo <gfa> 04 Jul '14

04 Jul '14

Hello i'm in the process to architect a new email system. i plan to use dovecot 2.2.9 (debian's wheezy). i would like to use maildir for 2 folders on each account (spam and no-spam) and the rest of the folders stored on mdbox. this should be opaque to my users. the reason for this, is i want to be able to train my anti-spam tools, but they read maildir or mbox, they don't read mdbox or dbox. but i want the other folders as mdbox (performance, backups, alternate storage) is there any way?, i prefer if is configurable in advance for all accounts but i could live with something that is done after account is created thanks! -- 1AE0 322E B8F7 4717 BDEA BF1D 44BB 1BA7 9F6C 6333

stripping extension from domain name
by Jerry 03 Jul '14

03 Jul '14

Thu, 3 Jul 2014 06:29:06 -0400 I know that the "%d" parameter is for the domain. Is there any way to use just the domain name sans its extension. EXAMPLE: example.com ==> example Also, I have a lot of logging going on in my dovecot log file. I want to limit it to just the barest amount, such as indicting what mail box mail was delivered to. Authentication errors, etcetera should only be shown if an error occurs. Is this possible? Thanks! -- Jerry

ACL configuration migration from Dovecot 2.1.17 to 2.2.13
by Iavor Stoev 03 Jul '14

03 Jul '14

Hello, I'm preparing migration to the latest Dovecot version 2.2.13 from the previous stable branch 2.1.17 which is deployed on my servers. With version 2.1.17 I use global acl dir to prevent all mail users to delete their INBOX.Junk Mail folder, which is part from our spam protection system. My current config is: cat /etc/dovecot/acls/INBOX.Junk\ Mail owner lrwstiae With version 2.2.13, the global acl dir support is disabled (with the above config, the imap server shows no folders at all) so I must use global acl file. The problem is that the "INBOX.Junk Mail" folder contains space character and I tried to escape it with "",'',/ and enclose the whole name with "" & '' without success. If I change the acl config to INBOX.Mail it works OK. The syntax of my global acl file is: cat /etc/dovecot/acls INBOX.Junk Mail owner lrwstiae The error is: Error: Global ACL file /etc/dovecot/acls line 1: Unknown ID 'Mail' Please advise Iavor Stoev Project Manager // Head of System & Network Administration Department

Bug/feature: mail fs pollution on IMAP select namespace/{non-existent}
by Peter Benko 03 Jul '14

03 Jul '14

Hi all, I have noticed a strange behavior with dovecot (tested with 2.2.13). I use shared folders to share mailboxes between users. I have a namespace called "Accounts" that hosts the shared folder for the users (prefix Accounts/%%n/). However, When I issue an IMAP select command on a random non-existent mailbox name under "Accounts", dovecot auto-creates it and pollutes my mail root directory: Python test code snippet: imapConn=imaplib.IMAP4_SSL(serverIP, serverPort) imapConn.login(serverLogin, serverPass) print imapConn.select("Accounts/NonExistentMailbox") imapConn.logout() Resulting in this: drwxr-x--- 1 vmail vmail 4096 Jun 12 10:00 _attachments_ >>> drwx------ 1 vmail vmail 4096 Jun 24 14:27 NonExistentMailbox <<< drwxr-x--- 1 vmail vmail 4096 Jun 24 00:54 user1 drwxr-x--- 1 vmail vmail 4096 Jun 24 01:24 user2 ... -rwxr-x--- 1 vmail vmail 72 Jun 24 14:27 shared-mailboxes.db ls -l NonExistentMailbox/ -rw------- 1 vmail vmail 0 Jun 24 14:27 dovecot-acl-list drwx------ 1 vmail vmail 4096 Jun 24 14:27 mailboxes <<< (empty) I attached a debug log and and my sanitized dovecot config. Please help! Is this a bug or a feature? I assume it might even cause more serious problems e.g., if I would select "Accounts/_attachments_" or something similar... I noticed this behavior with the latest Thunderbird client when I tried to subscribe to shared folders and it started to pollute my mail dirs (which signals that Thunderbird might be also buggy as it should not select non-existent folders under "Accounts"). I just reproduced it for simplicity with the above python script.

[Dovecot] zlib maildir reindex broken
by Richard Platel 03 Jul '14

03 Jul '14

I posted to the list about this a while ago but never got a response, I have a bit more information now. Dovecot 2.2.12 and other 2.2 versions are broken when using zlib and maildir. If messages are re-indexed, the INTERNALDATE of all messages is set to the time the re-index is done. The problem seems to be in src/plugins/zlib/zlib-plugin.c in the function zlib_mail_cache_open. During a reindex maildir_mail_get_received_date() does an i_stream_stat on the the i_stream_seekable stream created in zlib_mail_cache_open, but this istream does not know about the original maildir message file and always returns the current time for the file's stat times. This is also broken on initial index, but if mail is indexed when it's received (ours isn't) it coincidentally gets the right time.

BUG: segfault in auth when user listed multiple times in LDAP

Hi, I think I found a bug in the auth module. It can be triggered when the userdb is in LDAP and an user is found multiple times in LDAP.

Bug in quota_get_status
by Franz Knipp 03 Jul '14

03 Jul '14

Hi, the configuration option lmtp_rcpt_check_quota = yes didn't work, so I traced down the problem: quota_get_status (quota_storage.c:89) calls quota_test_alloc (quota.c:1352) with size = 0 bytes, which leads always to a FALSE result in quota_is_over (quota.c:1305). I've fixed the function quota_is_over by considering ctx->bytes_over and ctx->count_over. See the included patch. Kind regards, Franz -- Franz Knipp, +43 664 3980169 qnipp GmbH, Hauptstraße 54, 7064 Oslip, Österreich http://qnipp.com http://qnipp.com/qnipp.vcf

Mailboxes are in Maildir format. Any good backup tips? Had success with version control?
by deoren 03 Jul '14

03 Jul '14

I'm still pretty new to running a mail server, but one thing I've come to appreciate over the years is a good backup strategy. Since I have always run my own servers for practice and for personal use I don't have access to Enterprise backup solutions. Because of that I usually just fall back to scripts and tarballs and offload the content on a regular basis. Right now I'm using LVM snapshots + tarballs for daily backups, but I'd like to get better coverage for incremental changes that occur throughout the day. The size of existing content is low, but (small) changes are frequent. I went with Maildir format because based on my reading it is referred to as time tested and corruption resistant. Because individual emails are stored as separate files this also leads me to believe that a version control system (Git, SVN) would allow for easy point in time restores. I'm also going to research the GNU tar utility's support for incremental archives as that sounds promising. Suggestions and warnings are most welcome. Thanks!

doveadm director userdb

How do you configure an iterate_query SQL lookup for the doveadm director? I tried: service director { userdb { ... } } but userdb is not a valid stanza for director. I do not have a default userdb stanza, all my userdb definitions are specified in service imap/lda/lmtp blocks. Thanks. G H

Greetings, I'm getting reports from a user who's reading and deleting mail on Thunderbird, but read flags and deletions don't show up in his Android phone. He's using the native Android mail app with the newest Android OS. My question is, where do I start with troubleshooting this kind of issue? Thanks for anyone's insight here.

[Dovecot] TLS/SSL for Win8 & Outlook
by Sebastian Goodrick 02 Jul '14

02 Jul '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello I recently upgraded to dovecot 2.1.7 (as supplied with Debian Weezy). All clients work as expected except for Outlook (2013 &2010) on Win8 with a SSL/TLS connection. (Thunderbird on Win8 and Outlook 2013 on Win 7 works fine. On my previous dovecot version 1.2.13 all clients worked.) As far as I understand, one difference is the support for TLS1.2 and SSL3. And on the client side Win8 is now connecting through the Microsoft Unified Security Protocol Provider. My logs show these issues: Dovecot: May 06 21:05:43 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [78.42.x.x] May 06 21:05:43 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [78.42.x.x] May 06 21:05:43 imap-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [78.42.x.x] May 06 21:05:43 imap-login: Info: Disconnected (no auth attempts in 0 secs): user=<>, rip=78.42.x.x, lip=144.76.x.x, TLS handshaking: Disconnect Outlook 2013 (contains German, translation in []): IMAP: 12:30:02 [db] Mit 'mail.xxx.de' wird eine Verbindung an Port 143 hergestellt.

[Dovecot] lazy_expunge and shared folders
by Florian 02 Jul '14

02 Jul '14

Hi, since migration to Dovecot 2.2 I have troubles with lazy_expunge as soon as a user shares a folder. The user the folder is shared to cannot login anymore, dovecot logs Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' - When no folder is shared lazy_expunge is working fine, deleted mails are moved to the expunged namespace and can be recovered without any problems. - Sharing folders works as long as I disable lazy_expunge. I have used the config (with minor changes) with dovecot 2.0 for years without any problem. Switching to dovecot 2.2.10 (atrps repository) or 2.2.12 (dovecot enterprise repo) lazy_expunge and acl do not work together anymore. Is it a bug, a known limitation or is something wrong with my config? Any hints are welcome.

http://www.imapwiki.org/ImapTest/ <http://www.imapwiki.org/ImapTest/> I am doing imap testing using imaptest scripts. But, i am unable to append message. APPEND INBOX "15-Jun-2015 05:30:05 -0700" "From:abc@gmail.com" "Subject: test. HI this is msg". This command i am using in my testing script. Command executed properly. But, it is not appending mail which is i entered into command. Imaptest appending his own mail into mailbox. please tell me whether i am doing it wrong way. How to append msg i entered into command using imaptest ?? -- View this message in context: http://dovecot.2317879.n4.nabble.com/Imaptest-script-testing-tp48607.html Sent from the Dovecot mailing list archive at Nabble.com.
