Hi, I am having the same issue as: http://www.dovecot.org/list/dovecot/2014-April/095681.html although I am using the latest dovecot-core and dovecot-lucene packages from the debian sid repo which already has the patch (http://hg.dovecot.org/dovecot-2.2/rev/5e42a8c18b51) mentioned in the above thread implemented. doveadm(admin): Info: Old.All: Caching mails seq=1..300332 9400/300332 Program received signal SIGSEGV, Segmentation fault.

Dovecot failing with exit code 19200 in cron job
by Murray Trainer 18 Aug '14

18 Aug '14

Hi All, I am synchronizing a few hundred dovecot mailboxes with a perl script via a crontab. It works for a while (ie exit status=0) but the rest then start failing with exit code 19200. I tried redirecting STDERR but showed nothing. I suspect the cron job is hitting some sort of resource limit? If I run the perl script from the command line it appears to dsync all the accounts OK. The relevant part of my Perl code is below. Any ideas? Thanks, Murray foreach (@userlist) { my $email = $_; chomp ($email); # get rid of CR logit("Started sync of mailbox $email") if $debug; my $dsync_command="dsync -v -D -u $email mirror ssh -C root@$mailstore dsync -u $email"; logit("dsync_command=$dsync_command"); # Run dsync of mailbox logit("Started secondary sync of $mailbox to $mailstore") if $debug; my $exit_status = system ( $dsync_command ); logit("Dsync exit status: $exit_status") if $debug; logit("Finished secondary sync of $mailbox to $mailstore") if $debug; }

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

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

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.

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.

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

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?

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.

Any ideas? Andreas

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

prefix behavior with Dovecot / Squirrelmail
by Will Yardley 05 Aug '14

05 Aug '14

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
