[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.

Direct groups of users to pairs of backend mailstores?
by Murray Trainer 02 Jul '14

02 Jul '14

Hi All, We are using Dovecot in a Director setup with two director proxies, six backend mailstores, mailbox storage in NFS, and user accounts stored in LDAP. Currently we have five NFS filesystems on EMC VNX storage which are all mounted on each of the six backend mailstores. At the moment all users could be directed to any of the six mailstores. We have a group of users with very large mailboxes we want to put on separate cheaper Backblaze NFS storage. Because this will be less reliable than our VNX storage we want to be able to direct this group of users to a new pair of backend mailstores that only have the Backblaze NFS mounts. This would isolate the rest of the users isolation from problems with the Backblaze NFS servers. I have read the Dovecot documentation which indicates it is possible to direct users always to a single backend server. Can Dovecot direct users to a pair or more of backend mailstores - ie a subset or another set of mailstores. If not it would be a great enhancement which would allow more scalability, flexibility and redundancy. Thanks Murray

Managing users and home dirs
by deano-dovecot＠areyes.com 02 Jul '14

02 Jul '14

For those of you using virtual users, and SQL, how are you managing your users and their home dirs ? That is, what process do you use for adding/deleting users, creating their home dirs etc ? I suppose it's easy enough to do manually, inserting rows in the database, creating dirs, chown/chmod yada yada, but there must be a better way to do it ... If you're doing dovecot replication then it gets even more cumbersome, having to duplicate the effort in two places (and make sure it's correct). I have a nice test setup using Percona XtraDB Clustering in a 3-node cluster which works swimmingly, albeit in VMs only at the moment. A master DB node and two dovecot nodes. Dovecot replication is up and running nicely too, and I almost have all the communications going over ipsec tunnels, so it will be nice and secure. I'm thinking of something like a cronjob with two tasks, the first would periodically scan the home dirs and compare the users to what's in the database. When it finds a new userdir (plus a file labeled PASSWD) the script would add the user to the database, create the Maildir and whatever else, then delete the PASSWD file. DB replication will push that to the other nodes. The second task is scanning the user database and comparing to the home dirs - basically opposite of the first cronjob. When it finds a user in the DB that doesn't have a home dir, it would create it and whatever else is needed. This way, to add a user one would just create a PASSWD file in /var/mail/domain.com/newusername/PASSWD on either of the dovecot replication partner systems. The first cronjob task would discover the newusername dir, create the user in the DB, create the Maildir, chown/chmod etc. and delete the PASSWD file, so it's ready to go on that system. DB replication pushes the user table to the other nodes. The second task on the other dovecot system will discover a new user in the DB that doesn't have a home dir, and do its thing to create it all. So the whole create-a-new-user process becomes something like this on either dovecot system : mkdir -p /var/mail/domain.com/newusername ; echo "changeme" > /var/mail/domain.com/newusername/PASSWD A max of 5 minutes later the user is added to the database, and the home dir/Maildir/etc/etc is created on both dovecot systems.

i need a little advice with dovecot master user
by Francesco 02 Jul '14

02 Jul '14

Hello, As a step to migrate to a newer version of dovecot, i've been asked to configure a master user for logging in into mailboxes of a dovecot 1.2. I've followed the instructions from this page: http://wiki1.dovecot.org/Authentication/MasterUsers but appearently something is going wrong. I've turned on the auth verbose and what i get in the log is: 2014-06-30 15:25:03 auth(default): Info: passdb(administrator,127.0.0.1,master): Master user logging in as user(a)domain.tld but the output from a telnet session says: Trying 127.0.0.1...

Login failure with SElinux enforcing + Sqlite user DB
by G H 30 Jun '14

30 Jun '14

I am having a very strange issue with Dovecot + Sqlite + SELinux in enforcing. I am able to log in via IMAPS if SELinux is in permissive, but not able to do so when in enforcing. I do not see any SELinux denials even with dontaudit's enabled. I am running Centos 5 on x86_64 with a customized kernel build and SElinux Strict policy. The log dumps below are in the following order: 1. My syslog output when SElinux is enforcing 2. My mail client's protocol log (using Sylpheed) 3. My syslog output when SElinux is permissive. From the audit log, syscall 2 (from the message "type=SYSCALL ... syscall=2 success=no" appears to be sys_open for x86_64 architectures. syscall 87 is sys_unlink. Why is my mail client getting a SQL error message even though dovecot's auth log reported login success? Is this a sqlite problem instead of a dovecot one? FYI, I am using dovecot-2.2.10 (from ATrpms.net) and sqlite-3.3.6-7 There appears to be several options related to the temporary store on sqlite's documentation, the solution may be to use memory (instead of files) for temporary tables... dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so dovecot: auth-worker(29695): Debug: sql(mailadmin,10.0.77.80): query: SELECT password FROM users WHERE username = 'mailadmin' dovecot: auth: Debug: client passdb out: OK 1 user=mailadmin dovecot: auth: Debug: master in: REQUEST 3487432705 29692 1 17d4d0374be5dec51ce20917470caed8 session_pid=29696 request_auth_token dovecot: auth-worker(29695): Debug: sql(mailadmin,10.0.77.80): SELECT username FROM users WHERE username = 'mailadmin' AND view_mail = 't' AND 'imap' = 'imap' dovecot: auth: Debug: master userdb out: USER 3487432705 mailadmin uid=97 gid=12 home=/var/mail/mailadmin auth_token=e0d0ed3080574ab089f1a5302d43110ffa15ec42 dovecot: imap-login: Login: user=<mailadmin>, method=PLAIN, rip=10.0.77.80, lip=10.0.78.223, mpid=29696, TLS, session=<0C+M3A/9OwCsEQFQ> audispd: node=myhost.somewhere type=SYSCALL msg=audit(1404144473.421:46298): arch=c000003e syscall=2 success=no exit=-13 a0=7fff97f77ce0 a1=c2 a2=1a4 a3=0 items=1 ppid=29697 pid=29699 auid=7033 uid=8 gid=12 euid=8 suid=8 fsuid=8 egid=12 sgid=12 fsgid=12 tty=(none) ses=108 comm="sqlite3" exe="/usr/bin/sqlite3" subj=system_u:system_r:dovecot_t:s0 key="access" audispd: node=myhost.somewhere type=CWD msg=audit(1404144473.421:46298): cwd="/var/run/dovecot" audispd: node=myhost.somewhere type=PATH msg=audit(1404144473.421:46298): item=0 name="./sqlite_ZPh8vGq4ia1CCsJ" inode=8192027 dev=fb:02 mode=040755 ouid=0 ogid=97 rdev=00:00 obj=system_u:object_r:dovecot_var_run_t:s0 audispd: node=myhost.somewhere type=EOE msg=audit(1404144473.421:46298): audispd: node=myhost.somewhere type=SYSCALL msg=audit(1404144473.422:46299): arch=c000003e syscall=2 success=no exit=-13 a0=7fff97f77ce0 a1=c2 a2=1a4 a3=0 items=1 ppid=29697 pid=29699 auid=7033 uid=8 gid=12 euid=8 suid=8 fsuid=8 egid=12 sgid=12 fsgid=12 tty=(none) ses=108 comm="sqlite3" exe="/usr/bin/sqlite3" subj=system_u:system_r:dovecot_t:s0 key="access" audispd: node=myhost.somewhere type=CWD msg=audit(1404144473.422:46299): cwd="/var/run/dovecot" audispd: node=myhost.somewhere type=PATH msg=audit(1404144473.422:46299): item=0 name="./sqlite_9i9aIbK0rBuJWFS" inode=8192027 dev=fb:02 mode=040755 ouid=0 ogid=97 rdev=00:00 obj=system_u:object_r:dovecot_var_run_t:s0 ...

Does this configuration look sane? I seem to have a few duplicates and I am not sure if that is a problem or not.

Sieve seems to break mailbody during automatic redirection
by Urban Loesch 30 Jun '14

Hi, I have a strange problem with sieve. After upgrading to 2.2.13 sieve seems to break the mailbody during automatic redirection. I have the following configuration. - User A sends mail to User B. - User B has an automatic redirect to User C - User C geht the mailbody broken I did some debugging. This is a part of the mailbody which i grabbed from the mailqueue before the mail gets delivered to user B: ...

The part of the mail-header looks normal. But as you can see at beginning of the mailbody something inserts the strange character "^M" after each newline. According to Google this is a endline charachter from Windows. And this seems to break some clients (Eg. Lotus Notes). With dovecot version 2.1.x I don't have this problem. Have you any solution for me? Many thanks Urban Loesch

Any issues with dsync between 2.1.7 and 2.2.9 ?
by deano-dovecot＠areyes.com 29 Jun '14

29 Jun '14

My current production system is running dovecot 2.1.7-7ubuntu1 on Ubuntu 13.04, and I'm building a new setup based on Ubuntu 14.04 with dovecot 2.2.9-1ubuntu2.1 - current standard in the repos. I'd like to use replication to get the mailstore from the old system to the new. Are there any caveats or gotchas to be aware of ? Is it possible to make it a one-way replication ? So problems or glitches on the new setup don't propagate to the old production ? Thanks - D.

Procmail to Sieve translation
by Gerhard Wiesinger 28 Jun '14

28 Jun '14

Hello, I'm trying to move from procmail to dovecot sieve. I found the translation script at http://www.dovecot.org/tools/procmail2sieve.pl It works well except the following use cases: * ^From:.*myemail@mydomain.com.* | formail -I"X-Priority: 2 (high)" -I"X-mydomain-com-seen: yes" | $SENDMAIL -oi \ myemail(a)mydomain2.com \ myemail(a)mydomain3.com :0c * ^From:.*myemail@mydomain.com.* ! +1123456789(a)mysmsprovider.com :0c * ^(To|Cc|Bcc):.*myemail@mydomain.com.* ! myemail(a)mydomain2.com myemail(a)mydomain3.com Is there a possibility to support these use cases (can be done manually)? How does forwarding to another domain work at the deliver process? :copy seems not to be supported, right? Thank you. Ciao, Gerhard

Dovecot virtual and SASL with Postfix
by Jerry 28 Jun '14

28 Jun '14

This is my first attempt to set up virtual users and sasl with Postfix. Can I use a regular password file in this format: user:{plain}password user2:{plain}password2 or do I need to use a different format? I have been trying to find an example of a virtual user SASL file, but without any luck. I suck at Googling too. All of the mail will be delivered to :/var/mail/vmail/<domain>/<user> -- Jerry

mixing Maildir and mdbox
by gustavo panizzo <gfa> 28 Jun '14

28 Jun '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! PD: please keep me CC'ed as i'm not subscribed to the list -- 1AE0 322E B8F7 4717 BDEA BF1D 44BB 1BA7 9F6C 6333

Just did some more scripting and got a total of 1413 distinct emails (distinct queueids) that suffered from this 'message was expunged' problem on the 36 hours i got the problems. As noted before, not even a single one of these 1413 were nrcpt=1. Problems were from nrcpt=2 or greater. So, whatever this is, it really seems to NOT affect single recipient messages. As you suspected, on those 1413 the very first recipient ALWAYS got a status=sent from dovecot/lmtp. "Message was expunged" never happened on the very first recipient delivery. About the first user (the first delivered message) checking the message right after delivery, i tried to confirm that by the logs. To make things a little easier, i used nrcpt=2 and nrcpt=3 situations, just to avoid posting lots of logs here.

Despite of that, 2nd recipient got the message successfully delivered. But we have also a delay=22 ... maybe lmtp instance had already opened the message BEFORE it was erased by the 1st user ? this delay is high, i know that and, usually, server do NOT suffer from this delays on deliveries. Anyway, during this problem period, queues were pretty large and, thus, load was very high, which i think explains this unusual delays. With these two cases, it really seems that this is somehow related to: - lmtp as delivery agent - multiple recipient messages - first (or previous users in fact) checked and deleted the message before all the recipients got the message delivery About the two parameters, maildir_copy_with_hardlinks and pop3_fast_size_lookups, i'll try to change them one at a time and try to reproduce the problems. Fact is i only had the problem with both set to yes and problems were completly vanished when both were set to no. -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

imap/pop3/lmtp proxy question/problem
by Jogi Hofmüller 25 Jun '14

25 Jun '14

Dear list, We are finally back to our task of migrating from cyrus to dovecot. dovecot mostly does what we want in terms of POP3/IMAP server. Now we are preparing for migration. The plan is to use dovecot as proxy for not-yet migrated accounts. This works wonderfully for IMAP but not for LMTP.

sievec drops privileges unexpectedly
by Matthijs Kooijman 25 Jun '14

25 Jun '14

(Please keep me CC'd, I'm not subscribed) Hi folks, I'm using dovecot 2.1.7 (from Debian stable) with sieve. I have default sieve script configured, which lives in /etc/dovecot/sieve. I use dovecot-lda running under the virtual-mail user, which does not have write access to the /etc/dovecot/sieve directory. Now, when a mail gets delivered, I get the following message in my logs. Jun 25 14:29:43 mail dovecot: lda(2001): Error: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve/default.svbin.mail.local.18902.) failed: Permission denied (euid=2009(virtual-mail) egid=2009(virtual-mail) missing +w perm: /etc/dovecot/sieve, dir owned by 0:0 mode=0755) Jun 25 14:29:43 mail dovecot: lda(2001): Error: sieve: the lda sieve plugin does not have permission to save global sieve script binaries; global sieve scripts like /etc/dovecot/sieve/default need to be pre-compiled using the sievec tool Due to the lack of permissions, this is of course expected. However, when I then try to precompile the script using sievec, that also fails: # sievec /etc/dovecot/sieve/default sievec(root): Error: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve/default.svbin.mail.local.18952.) failed: Permission denied (euid=2009(virtual-mail) egid=2009(virtual-mail) missing +w perm: /etc/dovecot/sieve, dir owned by 0:0 mode=0755) So, apparently sievec drops privileges to the virtual-mail user. Why does this happen? It seems kind of counter-productive - I don't see a way to properly run sievec as root now? How is this supposed to work? Now I wrote this, I realized that it might be related that I have specified mail_uid and mail_gid globally in my dovecot.conf file. Perhaps those are intended to only be put inside the protocol imap and protocol lda blocks? This would mean duplicating of this bit of configuration, which doesn't really sound nice. Gr.

ot: accepting self certs into win pc?
by voytek＠sbt.net.au 24 Jun '14

24 Jun '14

few month ago, I've got a new Dovecot/Postfix server with self issued certificate (like the previous server), transferred users, all went well EXCEPT for one user on Win/Outlook (or Outlook Express) who tells me his new PC 'doesn't want to accept certificate' (sorry, I'm short on exact details at this time) I need to get it sorted out, I expect it 'should just work' like it did for other users, BUT, before I start looking, trying to 'educate myself' better if any one has any pointers, dos or don't regarding win email clients with self certified server, pls point me that way is using IE with www.dom.com/mycert.crt good point to start ? (after copying mycer.crt to web linked directory first?) thanks, V

Wheezy Dovecot workarounds
by Steve Litt 24 Jun '14

24 Jun '14

Hi all, In switching from Ubuntu to Debian Wheezy (7.5 64bit, network install), I'm finding some surprises in getting Dovecot to work. PROBLEM: As installed, the package manager doesn't give you the dovecot executable. WORKAROUND: To install the dovecot executable, you need to follow these instructions: http://wiki2.dovecot.org/HowTo/DebianStable PROBLEM: Even when you install Dovecot, it doesn't work, as evidenced by the inability of a local email client to talk to it. Further elements of the symptom are that nmap -A -T4 LocalIPAddress, whether LocalIPAddress is the IP of eth0, or 127.0.0.1, fails to find any open ports. Telnet can't operate dovecot at port 143, and openssl can't operate it at 993. However, bizarrly, executing these same commands on a remote machine into the original machine (including accessing the machine's Dovecot from an email client) work perfectly. WORKAROUND To "solve" this problem, do the following raindance as root: ifdown lo ifup lo After the raindance, local access to Dovecot works perfectly, and all nmap commands perform as expected. LOL, hey man, don't shoot me, I'm just the messenger. SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance

Mangesieve security question
by Vijay Rajah 24 Jun '14

24 Jun '14

Hello, I have a dovecot 2.2.6 on a Linux platform. I have configured manageseive extension. I have opened the manageseive port (4190) to entire world. (since I need my thunderbird and other clients to create seive scripts). I just wanted to know if it is ok to open that port to everyone, and get some feedback on some security measures specific to manageseive. -Thanks in advance Vijay PS: I have taken reasonable server hardening measures. This question is specific to manageseive.

Wishlist: add a variable %{x509} expanding to the client cert in Dovecot-auth
by Guilhem Moulin 24 Jun '14

24 Jun '14

Hi there, As of Dovecot 2.2.9, it's possible to enable passwordless authentication using client certificates [1]: ssl_ca = </etc/ssl/ca.pem ssl_verify_client_cert = yes auth_ssl_username_from_cert = yes (Password checking can be bypassed by returning the extra fields ‘password= nopassword’ in the passdb when the variable ‘%k’ expands to "valid".) However this requires the server admin to set up a PKI. Having a variable %{x509} expanding to the X.509 client cert in Dovecot-auth would remove such hassle and instead provide a way to manage authorized clients in the fashion of OpenSSH's ‘authorized_keys’. Postfix has a similar configuration option: relay_clientcerts [2]. There, the keys for the lookup table can be either client cert fingerprints or public key fingerprints (the digest algorithm can be configured with smtpd_tls_fingerprint_digest). I can't see why %{x509} should digest the certificate and not merely PEM-encode it, but having another %{pubkey} variable expanding to the (PEM-encoded) cert's SubjectPublicKeyInfo block would surely be useful :-) I wonder if there are other folks interested in having the client cert available in the passdb. Thanks, cheers, -- Guilhem. [1] http://wiki2.dovecot.org/SSL/DovecotConfiguration#Client_certificate_verifi… [2] http://www.postfix.org/postconf.5.html#relay_clientcerts

ACL group-override question
by Peter Chiochetti 23 Jun '14

23 Jun '14

Trying to get ACLs working, very basic setup: Virtual users are put into different acl_group via passdb. > u:{PLAIN}B::::::userdb_acl_groups=g The global acl file restricts what they can do. > * group-override=g > * group=g lr Shouldn't this mean, that the group rights override the user rights? The effect that I see though is, that the user "u" then may not do anything, not even lookup and read. The wiki text is not fully clear to me: It tells about disabling access fully (probably by specifying a non-existent group?). But this can only be one way to use group_override… -- peter

ACL group vs. owner question
by Peter Chiochetti 23 Jun '14

23 Jun '14

A hopefully simple question regarding the use of ACLs - the spirit being of taking away most permissions first and then adding them back selectively: In the global ACL declaration I have: > * owner lr > * group=SYS lrwstipekxa The owner is put into the SYS group via userdb extra field in static passwd file ("archiv" is a system user, but pam is disabled for the server): > archiv:::::::userdb_acl_groups=SYS Still, the group permissions do not get applied: > root@host:/etc/dovecot# doveadm -D acl debug -u archiv INBOX > […] > doveadm(archiv): Debug: Added userdb setting: plugin/acl_groups=SYS > doveadm(archiv): Debug: Effective uid=1002, gid=1001, home=/home/archiv > doveadm(archiv): Debug: acl: No acl_shared_dict setting - shared mailbox listing is disabled > doveadm(archiv): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir > doveadm(archiv): Debug: maildir++: root=/home/archiv/Maildir, index=, indexpvt=, control=, inbox=/home/archiv/Maildir, alt= > doveadm(archiv): Debug: acl: initializing backend with data: vfile:/etc/dovecot/dovecot-acl > doveadm(archiv): Debug: acl: acl username = archiv > doveadm(archiv): Debug: acl: owner = 1 > doveadm(archiv): Debug: acl vfile: Global ACL file: /etc/dovecot/dovecot-acl > doveadm(archiv): Info: Mailbox 'INBOX' is in namespace '' > doveadm(archiv): Info: Mailbox path: /home/archiv/Maildir > doveadm(archiv): Info: All message flags are shared across users in mailbox > doveadm(archiv): Debug: acl vfile: file /home/archiv/Maildir/dovecot-acl not found > doveadm(archiv): Info: User archiv has rights: lookup read > doveadm(archiv): Info: Mailbox in user's private namespace > doveadm(archiv): Info: Mailbox INBOX is visible in LIST My question: Shouldn't this work? (In a stock setup.) PS: when I add "* group-override=SYS" to /etc/dovecot/dovecot-acl the user will not even be able to list INBOX. PPS: As an aside, the setup also switches any sytem or /virtual/ users during login in local.conf: > userdb { > driver = static > args = uid=archiv gid=archiv home=/home/archiv user=archiv > } but I get the above result without that switching when I make it read: > userdb { > driver = static > args = home=/home/archiv > } So I suppose that it's not relevant in this case… Thank you in advance -- peter

Hi. What is the best way to do this, please ? I can override with -o but this applies to source as I read the docs. So I wish to do something like this dsync mirror -u myuser(a)me.com mdbox:/home/mail/myuser/mdboxcopy With either of: 1) attachments stored within message so mail_attachment_dir for dest being blank Or 2) attachments stored in a sub directory of mdboxcopy eg mdboxcopy/attach/ Timo hints that this is possible, but I cannot see how to do this, Any ideas ?

config best practice
by Egbert 20 Jun '14

20 Jun '14

Hi! We will soon start upgrading our Ubuntu mail server (running 2.0.19) from 12.04.1 LTSto 14.04 LTS. The dovecot config is still pretty much in 1.x style; one flat file called dovecot.conf. I can easily switch to a dovecot.conf with the "!include" lines and rename my flat config file to local.conf. I've tested that and it works fine. I could also try to move all lines in local.conf to the different XX-.conf files in the conf.d subdir. What is wise and best practice? Should one edit the files in conf.d? Or will the files in conf.d be overwritten on an update of dovecot? Then I'll better stick to the way of working with the dovecot.conf with the !includes and local.conf and assume that all files in conf.d are default settings. TNX for any advise!

Sis attachment deduplication
by Laeeth Isharc 20 Jun '14

20 Jun '14

Hi. Two questions: 1. Is this now reasonably stable for large mailboxes (c 2mm messages)? 2. Will this leave the filename in the message body unchanged? So for example if I have the same attachment called proposalfromvendor.pdf and proposaltoclient.pdf in two different emails, will the original names be kept ? Or will it replace the filename with some kind of numeric hash ? Many thanks. Laeeth Sent from my iPad

IMAP Chunking Thunderbird
by MrLINK 20 Jun '14

20 Jun '14

Hi, using dovecot-2.0.9-7.el6.x86_64 on CentOS release 6.5 (Final) I have an issue with thunderbird imap chunking. Some attachments are corrupted, because Thunderbird is just storing the first chunk. Since there are some workarounds by editing the "mail.imap.fetch_by_chunks" via about:config this is not the best choice for me because every client has to be edited. Is there a way to set a central value on the dovecot server (i.e disable chunking since this is not a client behaviour only)? Thanks in advance!

Suggestion: Split login_trusted_networks
by Peter Mogensen 20 Jun '14

20 Jun '14

Hi, It seems the use of login_trusted_networks is overloaded. Example: * It's used for indicating which hosts you trust to provide XCLIENT remote IP's. * It's used for indicating from which hosts you trust logins enough to disable auth penalty. (like in a webmail) However... trustwise, this is trusting two different entities. The first case you put trust in the host. In the second case, you actually put trust in the user which uses the webmail (unless of course the webmail it self implements auth-penalties). So you can't have one set of hosts which you trust for XCLIENT and another set of hosts you trust for not being the origin of brute force attacks. /Peter

Replication and namespaces
by Laeeth Isharc 19 Jun '14

19 Jun '14

Hi. Replication in dovecot is running into trouble as it is trying to sync virtual namespaces and does not like it. dsync parameters With v2.2.9+ you can configure what parameters replicator uses for the doveadm sync command: replication_dsync_parameters = -d -N -l 30 -U The -f and -s parameters are added automatically when needed. Usually the only change you may want to do is replace -N (= sync all namespaces) with -n <namespace> or maybe just add -x <exclude> parameter(s). ........ What is the description of namespace that follows -n or -x? -x virtual Or -x 0/ Where 0/ is the prefix for my virtual namespace Does not seem to stop it trying to sync the virtual namespace... What should I be doing instead? Do I need to use all the parameters above? Or can I just use the -x ? Sent from my iPa

dsync initial replication failing
by Cassidy Larson 19 Jun '14

19 Jun '14

Trying to get my new storage server synced up using dsync replication with SSH. Followed the wiki and everything works great for the initial sync, for about 4 hours, then I get some errors and it stops replicating: dsync-local(user(a)host.com): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync dsync-local(user(a)host.com): Error: Remote command returned error 75: ssh -lusername <remote_ip> doveadm dsync-server -uuser(a)host.com -U It happened around 2am. I restarted the new server dovecot process and it started to copy back up again, and then happened about four hours later. I have about 10,000 accounts, and it chugs through the list to replicate pretty well (~300Mbps), so I know it's working. Just not sure why it's failing after it's working so great. Running 2.2.13 on both on FreeBSD. Both show this: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 5645 Waiting 'failed' requests 0 Total number of known users 9957 Any ideas? Suggestions? Thanks, Cassidy

I think you will hear from proponents of both styles. I would say use whatever works best for you. I personally use one dovecot.conf without any includes because I like having all my configs in one place. Less editing mutiple files, and less forgetting some configuration squirreled away in some conf.d file. Joseph Tam <jtam.home(a)gmail.com>

RFE: dnsbl-support for dovecot
by Reindl Harald 17 Jun '14

17 Jun '14

after having my own dnsbl feeded by a honeypot and even mod_security supports it for webservers i think dovecot sould support the same to prevent dictionary attacks from known bad hosts, in our case that blacklist is 100% trustable and blocks before SMTP-Auth while normal RBL's are after SASL i admit that i am not a C/C++-programmer, but i think doing the DNS request and in case it has a result block any login attemt should be not too complex setup a own honeypot and feed rbldnsd with the sources is quite easy and in case of a own, trustable RBL where no foreigners report somebody by mistake it's relieable and scales well over many machines and services as long services supporting it mod_security: http://blog.inliniac.net/2007/02/23/blocking-comment-spam-using-modsecurity…

[Dovecot] Replication with virtual users and static userdb possible ?
by deano-dovecot＠areyes.com 17 Jun '14

17 Jun '14

Is it possible to get replication working in a virtual user setup that uses a static userdb ? My environment is fairly simple and typical - there's a single system user (vmail) that owns all the home dirs (/var/mail/domain.com/user). The virtual users (userid@domain.com:secretpassword) are kept in a single file (/var/mail/domain.com/PASSWD) that's unique per domain, and referenced as a static userdb : passdb { driver = passwd-file args = scheme=plain username_format=%u /var/mail/%d/PASSWD } userdb { driver = static args = uid=vmail gid=vmail home=/var/mail/%d/%n } I know the wiki http://wiki2.dovecot.org/Replication states that user listing must be enabled, but that's not available for a static userdb. The wiki http://wiki2.dovecot.org/UserDatabase/Static also says that it shouldn't be a problem because it will use do a passdb lookup instead (except for PAM which isn't used here). Unfortunately, it's not working. I've testing with ssh : dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} mail_replica = remote:vmail@server2.domain.com as well as with straight tcp (SSL for later) mail_replica = tcp:server2.domain.com:999 /var/log/mail.err shows the problems ... Jun 3 11:30:53 server1 dovecot: auth: Error: Trying to iterate users, but userdbs don't support it Jun 3 11:30:53 server1 dovecot: replicator: Error: User listing returned failure Jun 3 11:30:53 server1 dovecot: replicator: Error: listing users failed, can't replicate existing data Anyone else have it working ? I'm sure it's something simple that I've just overlooked. Thanks - D.

Accessing a user mailbox from another user
by Angel L. Mateo 17 Jun '14

17 Jun '14

Hello, I'm looking for something maybe similar to master password but for final users and I don't know if there is already a way I could do it with dovecot. I have accounts that are used by a set of users who know their password. But I now want to remove this shared password and the users has to access to this shared account with their own password. Using shared folders is not an option (at least, not the first option) because of the behaviour our users are familiar with, such as: * They have and manage different sieve filters for the account * They have thier own Sent, Drafts, SPAM... for this shared account and their email client recognizes them as it (because they have its own account). What I'm looking for is something similar to master password, but for a user identifying as another regular user, not the "master" one. Do you know if there already is a way to configure a similar behaviour? I'm planning to configure an user and authentication backend (maybe pam) that gets users as <realuser>$<finaluser> and the realuser password, checks if <realuser> should access to <finaluser> and then returns <finaluser> mail location to dovecot. Any idea? -- Angel L. Mateo Martínez Sección de Telemática Área de Tecnologías de la Información y las Comunicaciones Aplicadas (ATICA) http://www.um.es/atica Tfo: 868887590 Fax: 868888337
