namspace management
by A. Schulze 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. 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..... Aug 01 21:32:03 auth: Debug: client passdb out: FAIL 2 user=info(a)xxx.com temp As you see it returned a FAIL, but the password was retrieved from the users file (see the cache hit). Now I changed the order of the passdb's in my config, to make passwd-file come first, and then LDAP. And what happend now, it started working ...

It works fine now, but it not clear to me why the order is so important. Could somebody explain this? Or is this some bug? Thanks Jean-Louis

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. The user is set in the .m4 file and permission/group/user is set in the auth socket correctly.

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

Hi! I have to excuse my behave and I am really sorry. Yesterday I wrote two mails to this list and they never showed up in the online archives where I checked it. So that's the reason for this testmail. I hope this mail is readable to all of you? Cheers, Michael

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
