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.....

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

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

doveadm pw with SHA512-CRYPT won't roundtrip

Hi, Not sure if this is a PBKAC or not:- root@ds3:/usr/share/postfixadmin# doveadm pw -s SHA512-CRYPT -p password {SHA512-CRYPT}$6$aUgGXP0UshkMj7hY$9JV4yMRsjIe/98CzmglYrMjf.9NJ.FXzxcLE9B0v3doCRUWo2wRncc6hg6VCs0DCUHQbeC/bRDZdGCge/nB/h/ root@ds3:/usr/share/postfixadmin# doveadm pw -t {SHA512-CRYPT}$6$aUgGXP0UshkMj7hY$9JV4yMRsjIe/98CzmglYrMjf.9NJ.FXzxcLE9B0v3doCRUWo2wRncc6hg6VCs0DCUHQbeC/bRDZdGCge/nB/h/ -p password doveadm(root): Fatal: reverse password verification check failed: Password mismatch root@ds3:/usr/share/postfixadmin# dovecot --version 2.2.9 It works ok with other schemes that i’ve tried (e.g. SSHA-512). Is this a bug, or my mistake? thanks Jon

Frequent error: unknown namespace Trash
by Michael Ludwig 12 Aug '14

Hello to all of you! ;-) My first post on this list. I frequently get this error in dovecot.log every time a user logs in and out: ============================= imap(mailaddress): Error: quota: Unknown namespace: Trash ============================= When I change my conf.d/90-quota.conf from "Trash" to ".Trash" (as this is the imap/maildir folder name, the error stays the same, but with the ".Trash" in dovecot.log This is what my 90-quoato.conf looks like: ============================= plugin { quota_rule = *:storage=2G quota_rule2 = Trash:storage=+100M quota_grace = 10%% } ============================= Where can I start my search, what is going wrong? Just for letting you know: This mailserver is a fresh and clean setup. I am using postfix/dovecotvimbadmin/mysql/spamassassin/clamsmtp. Cheers, Michael
