[Dovecot] Deleted mails in dsync backups
by Wolfgang.Friebel＠desy.de 22 Sep '13

22 Sep '13

Hello we are doing regular backups of the mdbox mail folders using dsync -u username backup mdbox:/somedir/BACKUPS/username (still with version 2.1.10, but 2.2.5 is in testing phase) We do observe that the directory size in the BACKUPS directory is growing with respect to the original mail folders. I believe this is due to deleted mails not being purged in the backup. We are doing regular doveadm purge -A cleanups, but this does (of course) not affect the backups and subsequent dsync backup runs seem not to clean up deleted mails in the backup either. Will the behaviour of the dsync backup command deal with deleted mails in the 2.2.5 release? If not, what could we do to get rid of the deleted mails in the backup (or is there another reason for the growth in size) We have e.g. after 9 month of running with 2.1.10 du -sk username 588520 du -sk /somedir/BACKUPS/username 863024 -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY

[Dovecot] Rfc: Limit the size of an email IN the mailbox
by Ralf Hildebrandt 22 Sep '13

22 Sep '13

Currently we're in the process of migrating Dovecot mailboxes to Exchange. This is all working very well, except for the occasional user, who used his/her Drafts folder as a file storage: They started writing an email containing lots of image attachments (and thus exceeding our maximum_message_size by far). So the mail never gets sent, but stays in the Drafts folder. Once I try moving that mail to exchange, it won't accept the message since it's too big. I think it would be interesting to have a limit on the total size of an IMAP object, just like in SMTP. Thought? -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] INBOX protected foldername?
by Hajo Locke 22 Sep '13

22 Sep '13

Hello, have a little problem with folders with name INBOX created by Users. Some Clients use a Prefix for their Folders. In our old setup (dovecot 1.2) it was possible to create a Folder INBOX in mbox-space with some Subfolders. These Subfolders of INBOX showed up in Mailclient at toplevel. Now we updatet to 2.1.7. In higher dovecot versions INBOX seems to be a kind of protected foldername. dovecot is not offering this folder in folderlist. If i rename it, the folder is available again. There are only a few users, so i could fix this manually. But how to explain this? I did not find a setting etc. which could explain this behaviour. Our Config is pretty standard: mail_location is unchanged some dovecot versions we use: mail_location = mbox:~/mail:INBOX=/var/mail/%u most of conf is out of the box and also used in older versions. only new is namespace inbox, but should also be default: namespace inbox { inbox = yes } Is there an explaination for this behaviour? Thanks, Hajo

[Dovecot] . (dot) in maildir folder names
by Christoph Anton Mitterer 21 Sep '13

21 Sep '13

Hi. Uhm... yeah as the topic implies I want to have . (dots) in my folder names... Unfortunately dovecot's maildirmake hasn't a -f switch as the one from courier/maildrop, but that one in turn is buggy[0] and doesn't encode any characters at all. In principle, maildir++ should allow[1] having (encoded) dots in folder names,... but I don't quite understand how the encoding actually works, cause UTF-7 seems to be already the encoded (without padding and such)... but . is . in UTF-7 as well. Does dovecot support this? At least my mail clients (well I only tried Evolution so far which sucks in so many areas)... couldn't create it... but I guess it's rather a stupid client issue. Anyone knows how it would be encoded? Interestingly, and this might be actually an inssue in doveocot when I create maildirs with non-ASCII chars without encoding these, e.g. maildir/.München/ (instead of the correctly encoded (.M&APw-nchen) Dovecot seems to "export" these to the clients,... at least Evolution shows it in the list of subscribable folders (even correctly as "München")... but it doesn't allow me to actually subscribe to it. Cheers & thx, Chris. [0] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=709555 [1] http://www.courier-mta.org/maildir.html#id351803

[Dovecot] Dovecot and CAPITALISATION = grrrr ;-(
by Ben 21 Sep '13

21 Sep '13

Hello, As far as I'm aware, email is case insensitive ? Dovecot however, seems to be taking offence at the fact that someone is sending mail to user(a)SOMEDOMAIN.XYZ. Postfix has no issues handling it, it when it gets passed over to Dovecot LMTP that I get log lines such as : Sep 17 13:48:22 ukc-vm02-mx01 dovecot: auth: passwd-file(user(a)SOMEDOMAIN.XYZ): unknown user However user(a)somedomain.xyz *DOES* exist in the passwd file. Just not with a capitalised domain ! I am confused. Ben

[Dovecot] mail-filter plugin v2.2 - corrupts IMAP indexes?
by Charles Cazabon 21 Sep '13

21 Sep '13

Hi, I'm trying out the mail-filter plugin (v2.2, with Dovecot 2.2.5 built from source), and it seems like any nontrivial filter causes some sort of index corruption that breaks IMAP use. i.e. using a null filter (basically `cat -`) for mail-filter.sh and mail-filter-out.sh appears to work fine, and the debug logging shows it's using the filters (though it reports the wrong Unix socket for one of them - not sure if that's an actual bug or just a copy&paste error where it logs it; there's a similar accidental use of the same Unix socket path in the readme for the plugin): Sep 15 14:24:03 imap: Debug: Loading modules from directory: .../dovecot/lib/dovecot Sep 15 14:24:03 imap: Debug: Module loaded: .../dovecot/lib/dovecot/mail_filter_plugin.so Sep 15 14:24:03 imap(charlesc): Debug: Effective uid=1000, gid=1000, home=/home/charlesc Sep 15 14:24:03 imap(charlesc): Debug: mail_filter: Filtering mail_filter via socket .../dovecot/var/run/dovecot/mail-filter Sep 15 14:24:03 imap(charlesc): Debug: mail_filter: Filtering mail_filter_out via socket .../dovecot/var/run/dovecot/mail-filter If I use a slightly more complex pair of filter scripts that just swap the case of all alpha chars in the message body (not headers), so this pair of filters results in the same output as the original message, something seems to get corrupted in the indexes, and the IMAP process fails to respond correctly to FETCH requests, and logs this: Sep 15 14:24:03 imap(charlesc): Debug: maildir++: root=.../Mail-test, index=, indexpvt=, control=, inbox=.../Mail-test, alt= Sep 15 14:24:03 imap(charlesc): Error: Cached message size smaller than expected (0 < 1092) Sep 15 14:24:03 imap(charlesc): Error: Maildir filename has wrong S value, renamed the file from .../Mail-test/new/1379276625.M25480P28541.ludmilla,S=0,W=1122 to .../Mail-test/new/1379276625.M25480P28541.ludmilla,S=1092 Sep 15 14:24:03 imap(charlesc): Error: Corrupted index cache file .../Mail-test/dovecot.index.cache: Broken physical size for mail UID 5 Sep 15 14:24:03 imap(charlesc): Error: read(BODY[]) failed: Invalid argument (FETCH for mailbox INBOX UID 5) Sep 15 14:24:03 imap(charlesc): Info: Disconnected: FETCH failed in=105 out=1176 It reports the size of the message changes, too, which is odd, as running the filters manually confirms the output is identical to the input. mail-filter.sh attached; mail-filter-out.sh is identical except using a different temp file name to avoid clashes. Am I doing something wrong? How can I prevent this "Corrupted index cache file" problem?

[Dovecot] SELECT: Bug in untagged response
by Michael M Slusarz 21 Sep '13

21 Sep '13

Dovecot 2.2.5 In selected state: C: 1 SELECT &#-&#/# S: 1 NO Mailbox name is not valid mUTF-7 S: * OK [CLOSED] Previous mailbox closed. I can verify that this only seems to happen when the mailbox name is incorrect mUTF-7. Things work fine if I access a non-existent mailbox: C: 1 SELECT non-existent-mailbox S: * OK [CLOSED] Previous mailbox closed. S: a NO Mailbox doesn't exist: non-existent-mailbox FYI: Switching to Dave C's workaround discussed here -- http://mailman2.u.washington.edu/pipermail/imap-protocol/2005-September/000… -- regarding servers that don't support UNSELECT. This would normally never happen on Dovecot since it supports UNSELECT; I'm intentionally ignoring that capability for testing purposes. I'm not pipelining a CLOSE with the above SELECT command, like Dave suggests, because the likelihood this SELECT will be successful is about zero and I'd rather avoid a BAD response to a CLOSE command, since it is plausible that a server could issue a CLIENTBUG response for a client that is trying to CLOSE a mailbox in Authenticated State. (Granted, a server could also plausibly issue a CLIENTBUG for identifying a mailbox in incorrect mUTF-7 also, but whatever.) michael

[Dovecot] Mountpoints with auto mounter
by Steffen Kram 21 Sep '13

21 Sep '13

Hi, I'm running dovecot on a OmniOS installation and I'm wondering what I can do about all those mount point warnings in my logfile. The problem occurs because of the running auto-mounter which manages my mail directories. Isn't it possible for dovecot just try to access the directories before logging an error message. Shall I remove the corresponding mount points from the list of tracked mount points with the doveadm mount-command? The documentation does say nothing about situation with an active auto mounter. Thanks for any suggestions. Cheers, Steffen

[Dovecot] zlib_save per-user or per-mailbox?
by /dev/rob0 21 Sep '13

21 Sep '13

We'd like to be able to activate zlib_save per-user or per-mailbox, but it seems to be global, all or nothing. Search of this list revealed a comment from Timo in 2012: http://www.dovecot.org/list/dovecot/2012-March/064909.html where he was thinking that compression per-namespace would be a worthy feature. Was that done? I'm in the process of replacing a 2.0 system with 2.2 EE. The old system had zlib_save activated, but seems to deliver to maildirs without compression. Does a userdb_mail entry override global zlib_save? (I'm about to test that, but duh, I am asking first.) Thanks. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

[Dovecot] Bug report: "doveadm rename" encodes special characters wrongly in mUTF-7 (in fs)
by megodin＠inboxalias.com 21 Sep '13

21 Sep '13

Hello there, I'm pretty sure I found a bug in latest Dovecot 2.2.5.5 (EE) when playing with the doveadm command. Naturally renaming a users mail folder should be done via "doveadm es consistent. So when using "doveadm rename" trying to rename a folder with special characters e.g. german umlauts like "Ã¤" it seems to create the folder wrongly in the filesystem. Example: When I want to rename a users folder 'geschaftliches' to 'gesch&AOQ-ftliches' ("&AOQ-" is the correct mUTF-7 encoding for "Ã¤") using the command doveadm mailbox rename -u user 'geschaftliches' 'gesch&AOQ-ftliches' it ends up in the filesystem renamed as "gesch&-AOQ-ftliches" which has an falsely added "-" set after the "&" and therefore the folder is also wrongly shown in Mailclients like Thunderbird or web-mail systems like Horde. (Apparently "doveadm rename" supports only UTF-8 which shows up when trying to rename the folder with "doveadm mailbox rename -u user 'geschÃ¤ftliches'" I get the error message "Fatal: Mailbox name not valid UTF-8: geschÃ¤ftliches") To get things worse, when renaming the mailfolder in Thunderbird to "geschÃ¤ftliches" it gets correctly written in the filesystem as "gesch&AOQ-ftliches" - but afterwards it's NOT found anymore in the dovecot index, e.g. when trying doveadm force-resync -u user it is not listed anymore (until back-renaming in fs to the name it was indexed before). This problem can be reproduced. Can you please fix this? (Not sure if this might change - maybe add an option to support UTF-7 similar to doveadm mailbox list "-7" option) Thanks in advance, Megodin My (relevant part) dovecot configuration (dovecot -n): mailstorage @ NFS with nfsvers=3 (NetApp) # 2.2.5.5 (e5350245ad9b): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.22.1.el6.x86_64 x86_64 CentOS release 6.4 (Final) nfs auth_cache_size = 10 M auth_cache_ttl = 10 mins auth_debug = yes auth_master_user_separator = * auth_username_format = %n auth_verbose = yes disable_plaintext_auth = no listen = * lock_method = dotlock mail_debug = yes mail_fsync = always mail_gid = vmail mail_home = /mnt/placeholder/%u mail_location = sdbox:/mnt/placeholder/%u/mailstore mail_plugins = " quota fts fts_lucene" mail_privileged_group = mail mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mmap_disable = yes passdb { args = /etc/dovecot/users.blocked deny = yes driver = passwd-file } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts = lucene fts_lucene = whitespace_chars=@. quota = dict:User quota::file:%h/dovecot-quota quota_rule = *:storage=100M quota_rule2 = Trash:storage=+50M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=98%% quota-warning 98 %u sieve = /mnt/placeholder/%u/.dovecot.sieve sieve_dir = /mnt/placeholder/%u/sieve sieve_global_dir = /var/lib/dovecot/sieve/global/ sieve_global_path = /var/lib/dovecot/sieve/default.sieve } postmaster_address = postmaster(a)example.com protocols = imap pop3 sieve service auth { unix_listener auth-userdb { group = vmail user = vmail } } service managesieve-login { inet_listener sieve { port = 4190 } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { user = vmail } user = vmail } ssl_cert = </example.pem ssl_key = </example2.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } verbose_proctitle = yes verbose_ssl = yes protocol lda { mail_plugins = " quota fts fts_lucene sieve" } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = " quota fts fts_lucene imap_quota" } --- Alle PostfÃ¤cher an einem Ort.

Re: [Dovecot] Migrating from dovecot 2.1 to 2.2
by megodin＠inboxalias.com 21 Sep '13

21 Sep '13

Hey there micah, assuming you have your Dovecot set up using virtual users, I would advise you to use imapsync for that. It does incremental and recursive IMAP transfers from one mailbox to another (on different servers too). As it doesn't make a file copy, but let the two dovecot servers talk directly to each other via IMAP, all your mails with all flags, dates etc. will be preserved on the destination system exactly like on your source system. In your case also the indexes will be written on the fast system automatically by Dovecot 2.2.5 (if configured to do so), so this might do exactly what you are looking for. I have myself successfully transferred over 35000 accounts with imapsync (with very few problems, almost all of them because of corrupt mailboxes or special character encoding problems occured through former use of weird obsolete mail clients) and can highly recommend it.

What the heck, I don't get it... seems like it's bug's day for me today... the d*mn freenet web-mailclient omitted half of the sentence on exact the same part *again* - so I split it to several lines and omit some quotes... Hope this is the last try to get the _whole_ message out: Naturally renaming a users mail folder should be done via doveadm rename - and not via filesystems "mv" command - to keep dovecot indexes consistent. So sorry again for all that additional reading garbage (forum admins, please feel free to fill in the correct sentence to my original post and delete the 2 correction posts). Seems like a have to write another bug report to freenet admins... (sigh) Sorry again, Megodin --- Alle PostfÃ¤cher an einem Ort.

[Dovecot] Ring SYNC appears to have got lost, resending after upgrade
by Patrick Westenberg 20 Sep '13

20 Sep '13

Hi @all, on Saturday I upgraded two dovecot servers from squeeze to wheezy and dovecot from 2.1.x to 2.2.5 (compiled from sources). After the upgrade everything worked fine at first. On Sunday Morning I recognized these errors (they occured after a reload for logging purpose on midnight) on one server: director: Error: Ring SYNC appears to have got lost, resending After reloading/restarting both dovecot services the error occured on both servers. After some research I deleted some "zlib"-File which isn't needed anymore in dovecot 2.2.x and reinstalled dovecot. The error message disappeared. Today the error occured again (after the reload on midnight) and again on one node only until reloading/restarting the other node too. However, there is an additional error message: Sep 09 10:27:07 director: Error: Ring SYNC appears to have got lost, resending Sep 09 10:27:10 director: Panic: file login-connection.c: line 88 (login_host_callback): assertion failed: (strncmp(request->line, "OK\t", 3) == 0) Any ideas?

Since Dovecot now supports storing messages in s3 compatible storage (using obox) I was thinking about extending an object storage app I developed using node.js on top of Cassandra to implement the s3 API and see if that could breath some life into this concept. When time permits I suppose.

[Dovecot] passwd-file and MySQL
by Paolo 17 Sep '13

17 Sep '13

Speaking about multiple DB ... A my customer has a server (CentOS 6.x, dovecot 2.0.x, postfix, Squirrel+RoundCube with vacation and password plug-in), with about 3.000 users (about 200 different domains), all defined as system users and home as /home/mail/%user% The system works fine. Its only additional interest is authenticating users like user(a)domain.tld / password (maintaining also the current user.domain / password). Is it possible and How complex configuring a similar environment? Only matter of sync /etc/shadow and DB or other problems? Regards, Paolo

[Dovecot] both passwd-file and MySQL
by Andreas Meyer 16 Sep '13

16 Sep '13

Hello all! Wondering if it is possible to use a flat passwd-file for some domains and for some other a MySQL-database for queries? All of our domains are handled by passdb { args = /etc/dovecot/passwd driver = passwd-file } userdb { args = /etc/dovecot/passwd driver = passwd-file } Can one use MySQL in addition for another domain? Greetings Andreas

[Dovecot] Dovecot replies with default SSL certificate instead of the vhost's
by Shadi Habbal 16 Sep '13

Hello, I'm using dovecot v2.0.21.

[Dovecot] Change mail_location for one user?
by Scott Galambos 16 Sep '13

16 Sep '13

Hello, I'm running the latest version of dovecot on Linux with mbox mailboxes. Everything works fine. So in my dovecot config I have mail_location = mbox:~/mail:INBOX=/var/mail/%u I would like to now change the mail_location for one user in an attempt to slowly migrate to Maildir format. I'm confused how to do this. I'm running shadow passwords: $: doveconf -n passdb passdb { driver = shadow } Testing any given user gives: $: dovecot user sarah field value uid 1478 gid 116 home /home/sarah mail mbox:~/mail:INBOX=/var/mail/sarah system_groups_user sarah What would I have to do to make only sarah's mail_location ~/Maildir now? My userdb is: $: doveconf -n userdb userdb { driver = passwd } I tried following the wiki's but its confusing. Thanks for any help or tips.

Hello everybody, I'm trying to use the Dovecot antispam on Debian Wheezy (dovecot version 2.1.7), but it's not working, each time I put a mail in the "Spam" folder, it is send in its original folder.

There are 1.0.1e packages for every Linux distro I've checked. my point is that it does not help much if you have the best of all available encryptions on your IMAP server because all the messages you receive pass the wire and since you can't disable SSL/TLSv1.0/TLS1.1 on the MTA side or if you do so you receive a lot of messages *completly unecnrypted* because the sending MTA falls back >>> Firefox and Thunderbird currently ship with TLS 1.1/1.2 support, >>> but not enabled by default >> >> so it is nut relevant > > How is TLS 1.1 and 1.2 support in one of the most popular suites of software not relevant? "but not enabled by default" is not relevant in the reality except you are the only user of your private server and even if see above what benefit do you have from TLS1.2 if the message passed the wire with SSL3 or unencrpyted at all > Sure, it's not enabled by default, but those of us working proactively can enable it taht will not go to happen for the majority of users > On by default simply means the feature has matured to the point where the cost of > supporting the general userbase is reasonably small. on by default means the ordinary users will use it off by default means the ordinary users will not use it >> as long the support for Windows XP is active and it comes to business >> you have to support it - period > > Yeah I know.

[Dovecot] Migrating from dovecot 2.1 to 2.2
by Micah Anderson 13 Sep '13

13 Sep '13

Due to the incompatibilities with the dsync protocol version between 2.1 and 2.2, I am unable to use dsync to move users to a new machine where we have 2.2.5 setup. This wouldn't normally be a problem, as I could just rsync the user's mdbox and dovecot would happily do the right thing. However, on the new system I've placed the indexes into a faster storage medium, where on the older system the indexes were included in their mail directory. I can rsync over the entire thing, including their old indexes, and dovecot will try to do the right thing and build new indexes, but what happens is all mail is marked as unread, and I get some old index cruft left around in the directories. How can I preserve the seen/unseen flags in such a migration? Thanks! micah

I wonder if there is a way to confirme sa-learn is correctly feeded by the antispam plugin. dovecot version : 2.1.7 spamassassin version : 3.3.2 (both packaged in debian stable, with postfix and amavis) i configured dovecot's antispam plugin this way : plugin { ... #Antispam antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_trash = Trash antispam_spam = Junk antispam_allow_append_to_spam = no antispam_pipe_program = /srv/datadisk01/bin/sa-learn-pipe.sh antispam_pipe_program_spam_arg = --spam antispam_pipe_program_notspam_arg = --ham } refering to : http://wiki2.dovecot.org/Plugins/Antispam using that script to pipe message to sa-learn : #!/bin/sh echo /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt ; echo "$$-start ($*)" >> /tmp/sa-learn-pipe.log ; #echo $* > /tmp/sendmail-parms.txt ; cat<&0 >> /tmp/sendmail-msg-$$.txt ; /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt ; rm -f /tmp/sendmail-msg-$$.txt ; echo "$$-end" >> /tmp/sa-learn-pipe.log ; exit 0; here is what i got when i move a mail to Junk folder : Sep 11 18:10:10 effraie01 imap: antispam: plugin initialising (2.0-notgit) Sep 11 18:10:10 effraie01 imap: antispam: verbose debug enabled Sep 11 18:10:10 effraie01 imap: antispam: "Junk" is exact match spam folder Sep 11 18:10:10 effraie01 imap: antispam: no unsure folders Sep 11 18:10:10 effraie01 imap: antispam: "Trash" is exact match trash folder Sep 11 18:10:10 effraie01 imap: antispam: pipe backend spam argument = --spam Sep 11 18:10:10 effraie01 imap: antispam: pipe backend not-spam argument = --ham Sep 11 18:10:10 effraie01 imap: antispam: pipe backend program = /srv/datadisk01/bin/sa-learn-pipe.sh Sep 11 18:10:10 effraie01 imap: antispam: pipe backend tmpdir /tmp Sep 11 18:11:10 effraie01 imap: antispam: plugin initialising (2.0-notgit) Sep 11 18:11:10 effraie01 imap: antispam: verbose debug enabled Sep 11 18:11:10 effraie01 imap: antispam: "Junk" is exact match spam folder Sep 11 18:11:10 effraie01 imap: antispam: no unsure folders Sep 11 18:11:10 effraie01 imap: antispam: "Trash" is exact match trash folder Sep 11 18:11:10 effraie01 imap: antispam: pipe backend spam argument = --spam Sep 11 18:11:10 effraie01 imap: antispam: pipe backend not-spam argument = --ham Sep 11 18:11:10 effraie01 imap: antispam: pipe backend program = /srv/datadisk01/bin/sa-learn-pipe.sh Sep 11 18:11:10 effraie01 imap: antispam: pipe backend tmpdir /tmp Sep 11 18:12:04 effraie01 imap: antispam: mailbox_is_unsure(Junk): 0 Sep 11 18:12:04 effraie01 imap: antispam: mailbox_is_trash(INBOX): 0 Sep 11 18:12:04 effraie01 imap: antispam: mailbox_is_trash(Junk): 0 Sep 11 18:12:04 effraie01 imap: antispam: mail copy: from trash: 0, to trash: 0 Sep 11 18:12:04 effraie01 imap: antispam: mailbox_is_spam(INBOX): 0 Sep 11 18:12:04 effraie01 imap: antispam: mailbox_is_spam(Junk): 1 Sep 11 18:12:04 effraie01 imap: antispam: mailbox_is_unsure(INBOX): 0 Sep 11 18:12:04 effraie01 imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Sep 11 18:12:04 effraie01 imap: antispam: running mailtrain backend program /srv/datadisk01/bin/sa-learn-pipe.sh Sep 11 18:12:04 effraie01 imap: antispam: running mailtrain backend program /srv/datadisk01/bin/sa-learn-pipe.sh Sep 11 18:12:04 effraie01 imap: antispam: running mailtrain backend program parameter 1 --spam and here is what i got in /tmp/sa-learn-pipe.log: 10545-start (--spam) 10545-end For me, it's working, but when i run sa-learn --backup, i just get this : v 3 db_version # this must be the first line!!! v 0 num_spam v 0 num_nonspam it's probably cause i'm using ***STANDARD-ANTI-UBE-TEST-EMAIL*** wich probably teach nothing to sa-learn, but i wonder if i can find somewher a log or something confirming sa-learn correctly get the email i pipe to it. thanks a lot in advance -- Mathieu

[Dovecot] Plugin antispam - mailtrain realtime sa-learn
by Hans Spaans 13 Sep '13

13 Sep '13

Hi, On Dovecot Wiki2[1] it is written that you need a wrapper script for sa-learn as it shouldn't support pipped input, but that is supported since SpamAssassin 2.6 at least. As far as I can see and test, the following config makes it work without a wrapper script. Can someone confirm it before the wiki is updated? plugins { antispam_backend = pipe antispam_trash = Trash antispam_spam = Junk antispam_mail_spam = --spam antispam_mail_notspam = --ham antispam_mail_sendmail = /usr/bin/sa-learn } Hans [1] http://wiki2.dovecot.org/Plugins/Antispam

by Mohsen Pahlevanzadeh 13 Sep '13

13 Sep '13

Dear all, I install postfix ,postfix-mysql,dovecot-core,dovecot-mysql,dovecot-pop3,dovecot-imapd and postfixadmin form debian repo. Also i configured postfixadmin. It work fine with mbox storage, But i need to change it to my path/domain/users i saw devecot have mail_location directive. i changed it to : mail_location = maildir:/var/pool/%d/%u My questions are: 1. how can i assign mail_location directive to a maildir storage according to my path and domain/user , such as qmail? 2. i want to mysql, i need to write bash script to add/delete/update for doing them ? or dovecot provides them with command line? 3. What's permission of path in mail_location ? 4. How can i enable mysql in dovecot? My dovceconf -n is: ////////////////////////////////////// # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.1 ext4 mail_location = maildir:/var/pool/Maildir/%d/%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 pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } ///////////////////////////////////////////////////// Yours, Mohsen

[Dovecot] Problem getting a dovecot proxy to connect to another dovecot machine via STARTTLS
by Arnoud van Heuvelen 12 Sep '13

12 Sep '13

Hi, I'm having a bit of a problem trying to setup a dovecot proxy. I have a setup with two nodes. One is a working Dovecot/Postfix mail server (node a). The other is running a dovecot proxy and roundcube webmail. Currently I can telnet to port 143 (or openssl s_client to port 993) to localhost on node b. I can then login to a test account on node a. This all works. However, once I instruct the proxy to use SSL or TLS my problems start. When I try to login on node b (both on port 143 and 993), it will send two TCP packets on port 993 to node a. There is no TLS handshake. Consequently, my telnet session will just hang until dovecot reaches a timeout. It will then disconnect me for inactivity. I can not find any information in the logs. To clarify, the dialog: Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot ready. a login atest(a)company.nl test123 * BYE Disconnected for inactivity. I have tried to use the following values in my proxy database: ssl='any-cert', starttls='Y' ssl='any-cert', starttls='any-cert' ssl=NULL, starttls='any-cert' Here is a strace of the imap-login process on node B: http://dpaste.com/1377232/ The illegal seek on line 30 of the strace looked suspicious to me. Here is the corresponding lsof: http://dpaste.com/1377239/ Here is node A's config: http://dpaste.com/1377247/ And here is node B's: http://dpaste.com/1377241/ This is node B's password query: password_query = SELECT NULL AS password, 'Y' AS nopassword, host, 'Y' as proxy, starttls, `ssl`, 10 AS proxy_timeout FROM proxy WHERE domain = '%d' The logs tell me the password query succeeds: Sep 12 16:32:35 auth-worker: Debug: sql(atest(a)company.nl,127.0.0.1): query: SELECT NULL AS password, 'Y' AS nopassword, host, 'Y' as proxy, starttls, `ssl`, 10 AS proxy_timeout FROM proxy WHERE domain = 'company.nl' Sep 12 16:32:35 auth: Debug: client out: OK 1 user= atest(a)company.nl host=31.CENCOR p roxy starttls=Yt ssl=any-cert proxy_timeout=10 pass=test123 Nothing after that. Node A's log gives me this: 2013-09-12 16:26:51 imap-login: Info: Disconnected (no auth attempts): rip=149.CENCORED, lip=31.CENCORED, TLS handshaking: Disconnected I'm running out of ideas. If anyone would be able to help I would be extremely grateful. Regards, Arnoud van Heuvelen

I think it's something more. Apparently it's not even looking at the database. Not sure what I didn't do. If anyone can point me to a good dovecot / mysql quota how to that would be helpful.

[Dovecot] Quota question.
by Bruce Markey 12 Sep '13

12 Sep '13

I have quotas setup with dovecot. Everything seems to be running fine. Values show up fine in mysql. I set up Roundcube to show quota amounts, this also works. For some reason it's showing the old value, I had upped a quot I assume that dovecot is reporting this wrong since roundcube talks to dovecot for its info. Imap debug info: [11-Sep-2013 15:57:47 +0000]: [5986] S: A0003 OK List completed.

[Dovecot] slow dict lookups?

In my case the dict is use for user / domain quotas and is looked up via Postgres (on another host). Is there further logging I can enable to see where the problem is? Thanks, Anand

[Dovecot] Double Maildir folders.
by Bruce Markey 12 Sep '13

Somehow in setting up quotas and sieve I somehow doubled my maildir. I noticed that when I logged into my webmail I didn't see the folders I created. I went to the actual location and noticed this. Mail location is set correctly in 10-mail.conf mail_location = maildir:/var/vmail/%d/%n/Maildir So I went to /var/vmail/domain/user and saw: drwx------ 8 vmail vmail 4.0K Sep 11 22:08 . drwx------ 4 vmail vmail 4.0K Sep 10 18:40 .. drwx------ 5 vmail vmail 4.0K Sep 11 22:04 .Sent lrwxrwxrwx 1 vmail vmail 21 Sep 11 15:44 .dovecot.sieve -> sieve/roundcube.sieve -rw------- 1 vmail vmail 199 Sep 11 15:45 .dovecot.svbin drwx------ 10 vmail vmail 4.0K Sep 11 18:40 Maildir drwx------ 2 vmail vmail 4.0K Sep 11 19:46 cur -rw------- 1 vmail vmail 51 Sep 11 19:47 dovecot-uidlist -rw------- 1 vmail vmail 8 Sep 11 19:47 dovecot-uidvalidity -r--r--r-- 1 vmail vmail 0 Sep 11 19:46 dovecot-uidvalidity.5230c8a2 -rw------- 1 vmail vmail 248 Sep 11 19:47 dovecot.index.log -rw------- 1 vmail vmail 24 Sep 11 19:47 dovecot.mailbox.log -rw------- 1 vmail vmail 15 Sep 11 22:08 maildirsize drwx------ 2 vmail vmail 4.0K Sep 11 19:46 new drwx------ 3 vmail vmail 4.0K Sep 11 15:44 sieve -rw------- 1 vmail vmail 5 Sep 11 19:47 subscriptions drwx------ 2 vmail vmail 4.0K Sep 11 19:46 tmp Which I shouldn't see correct?

The only two places I can think are 90-plugin.conf which are my sieve settings. plugin { # The location of the user's active script: sieve = ~/.dovecot.sieve # If the user has no personal active script (i.e. if the file # indicated in sieve= does not exist), use this one: sieve_global_path = /var/lib/dovecot/sieve/default.sieve # The include extension fetches the :personal scripts from this # directory. When ManageSieve is used, this is also where scripts # are uploaded. sieve_dir = ~/sieve # The include extension fetches the :global scripts from this # directory. sieve_global_dir = /var/lib/dovecot/sieve/global/ } But I don't see how that would affect it. And the password and user queries were changed for the quotas. password_query = SELECT username AS user, password,CONCAT('/var/vmail/', maildir) AS userdb_home,\ '5000' AS userdb_uid, '5000' AS userdb_gid,\ concat('*:storage=', quota) AS userdb_quota_rule\ FROM mailbox WHERE username='%u' AND domain='%d' AND active=1 user_query = SELECT CONCAT('/var/vmail/', maildir) AS home, 'maildir:~/' as mail, '5000' AS uid, '5000' AS gid,\ concat('*:storage=', quota) AS quota_rule\ FROM mailbox WHERE username='%u' AND domain='%d' AND active=1 maildir in the mailbox is domain/user/ <- do I have to concat on Maildir in the query?

[Dovecot] Need help with Replication

[Dovecot] Default mail folders.
by Bruce Markey 11 Sep '13

11 Sep '13

Just want to make sure before I set this up. I read that the autocreate plugin is deprecated and to use "Mailbox settings" as listed here http://wiki2.dovecot.org/MailboxSettings. If that is correct then do I just add those mailbox blocks in /etc/dovecot/conf.d/10-mail.conf? Lastly, will "sent items" auto populate with sent items or is there something else that needs to be done. I just switched over from courier and I'm still getting used to where/how things are done.

[Dovecot] Sieve, vacation, company (domain-wide) message possible?
by Charles Marcus 10 Sep '13

10 Sep '13

Hello, I've been using vacation.pl from postfixadmin for many years, and since the most recent modification that allows me to specify my own strings to test for for when NOT to send a message, I'm extremely happy with it (no more auto-responses to linked-in/facebook crap, etc)... But, there is one thing I'd like to be able to do that it can't do, and there hasn't been any positive response about implementing it, so I'm asking about if this is possible to do with sieve right now, and if not, how hard would it be to implement... What I'd like is to be able to set a company (domain-wide) auto-response for when our company is closed for holidays... more specifically, extra holidays (often the boss will close an extra day for an extra long weekend). He has asked more than once about setting an auto-response for *everyone* during these periods... Thanks, -- Best regards, */Charles/*

[Dovecot] Sieve Filter global vs user specific
by inkubus 10 Sep '13

10 Sep '13

Hi@all! I'm actually fighting to make sieve in dovecot work and made quite a success by now. However, I still fail at the following constellation: Background: I'm a Mail Admin of a small IT department and we are already using Dovecot as LDA with a filtering server. Any user can easily create filter rules that apply to him (to make it easier for my colleagues we use the Roundcube plugin for rule design). I can formulate global rules that apply to all. Individual users create their rules for redirectiong mails home (a la redirect: copy "users(a)theirhomes.de";) According to the policy of my company, certain file types (eg avi, mp4, mp3, wav, etc.) must NOT be sent out to the internet. But our phone system does INTERNALLY just that - receiving calls in absence of the user it sends mails with attachments MP3 (the spoken message). These mails must of course not be forwarded outside. I also created a global rule, which supresses the delivery of these mails (using the stop command), But after my global rule follows the user specific rule and the message ist sent anyway. QUESTION: Can cause dovecot somehow not to follow the user specific rules that apply to a message after going through my global ones? The mail has to remain directly in the inbox (and must not be forwarded by the user specific filter aftwerwards) My configuration: dovecot.conf (excerpt): plugin { sieve = /home/%n/.dovecot.sieve sieve_dir = /home/%n/.mailstore/sieve sieve_global_dir = /etc/dovecot/sieve/ sieve_before = /etc/dovecot/sieve/global } /etc/dovecot/sieve/global: require ["vacation","copy","fileinto","body","imap4flags"]; # rule:[Redirect] if anyof(header :contains "From" "f...ing.telefonanlage(a)firma.intern", header :contains "Subject" "Sprachnachricht") { stop; } user specific rules are as follows # rule:[Redirect] if true { redirect :copy "users(a)theirhomes.de"; } I hope my English is understandable (got quite a cold andfighting to keep my eyes open so my English is not the best today ;-) ) I'm sure the solution for this problem is a nobvious & simple one but I'm having my blond moments today... Any help would be appreciated! yours Sven P.S. Klar bin ich mir bewusst, dass einfach die Benutzerfilter aufgebohrt werden könnten. Da aber nicht alle Kollegen... sagen wir entsprechend firm... sind, würde ich den Pflegeaufwand gern gering halten und dieses Ausnehmen vo der weiterleitung zentralisieren. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Sieve-Filter-global-vs-user-specific-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Proxy and Master Config
by Regan Yelcich 10 Sep '13

10 Sep '13

I'm just sitting down to configure a Proxy & Master Dovecot setup with Postfix and virtual users. I have read plenty about how to configure Dovecot as a proxy, but I'm unclear what's required on the "master" end. Does the master need the -pop and -imap scripts? or does the proxy handle that and call -deliver on the master? Can anyone explain the basic setup so I get it right. Thanks.

Probably too quick (or perhaps you haven't configured dotlocking). Qpopper locks the INBOX when it creates a drop copy: this can be a time consuming operation, during which you can see the .$user.pop lock file. Dovecot is more intelligent: it doesn't create copies, and goes out of its way to avoid grautitous I/O. Most of the operations can be done by consulting the indices. However, I did contrive a situation to observe lock files being created. 1) Create large INBOX file test user (assuming mbox /inbox/testuser) 2a) In one window, run a shell loop monitor while : ; do ls -al /inbox/testuser.lock done 2b) In another window, create a POP3 session and do an operation that would require a lock: telnet pop-server 110 USER testuser PASS testpassword DELE 1 ... this still won't need locking -- not until ... QUIT If you use maildir format, it may still be too quick to catch. in this situation, you can process trace the pop3 worker process to verify a lock file is created. > Is this .pop file a lock file or just a temporary file? Temporary. If you have them lying around, qpopper crashed. Note: dovecot makes lockfiles of the form "$user.lock". > If its a temp file does dovecot do the same thing elsewhere? I'm > concerned dovecot is not locking properly and there will be mailbox > corruption, so I'm trying to get dovecot to mimic what qpopper does as > much as possible. By "mimic" you mean that locking works, but otherwise, you don't want dovecot to mimic qpopper: the former is much better. I have not had problems with users complaining about scrambled files. As I said, process trace your pop3 worker process if you need to verify the locking process. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] sieve vacation question
by Andreas Schulze 10 Sep '13

10 Sep '13

Hello Stephan, I love to use the vacation extension to build an echo service. I have not to worry about whether to answer or not if the sender is a list, postmaster, mailer-daemon or other crasy thing. But i like to echo the *complete headers* back. I did not found a solution with sieve yet. Is it really impossible? Thanks Andreas

[Dovecot] Is dovecot locking properly?
by Scott Galambos 09 Sep '13

09 Sep '13

Hello, I'm attempting to move form qpopper 4.1 to Dovecot 2.2.5 on Linux. When a user checks POP mail qpopper seems to make a .username.pop temporary file in the same /var/mail directory as the mbox INBOX file. Watching what dovecot does I don't see this happening. Is this .pop file a lock file or just a temporary file? If its a temp file does dovecot do the same thing elsewhere? I'm concerned dovecot is not locking properly and there will be mailbox corruption, so I'm trying to get dovecot to mimic what qpopper does as much as possible. I'm using procmail and its Locking strategies are: dotlocking, fcntl(), lockf(), flock(). I'm using sendmail too. I left dovecot's locking as the defaults. Thanks for any tips.
