[Dovecot] Append with literal+ and mailbox over quota
by Ewald Dieterich 19 Jul '12

19 Jul '12

I'm appending a mail with literal+ to a mailbox that is over quota: 1 APPEND INBOX {127+} From: <ewald.dieterich(a)fun.de> To: <ewald.dieterich(a)fun.de> Subject: Quota-Test Message-ID: <abcdefg(a)fun.de> Quota-Test 1 NO [OVERQUOTA] Quota exceeded (mailbox for user is full) 2 NOOP 1 BAD Error in IMAP command APPEND: Invalid arguments. 3 NOOP 3 OK NOOP completed. Somehow the first NOOP is considered to be part of the already failed APPEND. I have to add an empty line after to NO response for the NOOP to work: 1 APPEND INBOX {127+} From: <ewald.dieterich(a)fun.de> To: <ewald.dieterich(a)fun.de> Subject: Quota-Test Message-ID: <abcdefg(a)fun.de> Quota-Test 1 NO [OVERQUOTA] Quota exceeded (mailbox for user is full) 2 NOOP 2 OK NOOP completed. Can somebody confirm this to be bug? Here is the output of doveconf -n # 2.1.8: /usr/local/dovecot-orig/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.3 ext3 auth_debug = yes auth_verbose = yes debug_log_path = /var/log/dovecot/debug.log disable_plaintext_auth = no info_log_path = /var/log/dovecot/info.log log_path = /var/log/dovecot/error.log mail_debug = yes mail_location = mdbox:/var/spool/dovecot/%2.256Hu/%3.4096Hu/%u mail_plugins = notify mail_log quota acl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { driver = pam } plugin { acl = vfile autocreate = INBOX.Drafts autocreate2 = INBOX.Sent autocreate3 = INBOX.Trash quota = dict:User quota::file:/var/spool/dovecot/%2.256Hu/%3.4096/%u/dovecot.dict quota_rule = *:bytes=2000 } ssl = no userdb { driver = passwd } protocol imap { mail_plugins = notify mail_log quota acl autocreate imap_quota imap_acl

Hi, I'm using Dovecot 2.1.8. Is it possible to deactivate the "W=" Maildir filename extension, so that dovecot not add it to maildir filenames?

[Dovecot] Converting from Maildir format ?
by Nick＠5sg.eu 19 Jul '12

19 Jul '12

Hi again, I'm still trying to find out if anyone knows the correct way to either switch the existing Maildir multiple file format to the single file format I believe known as MBox. Failing that, though it'll mean a LOT of work for me to manually convert all of the existing Maildirs, how do I get dovecot to work in future in MBox single file format. I tried entering 'mail_location = mbox:~/mail:INBOX=/%h/%u' in the 'dovecot.conf', but it still saves each message in a file of its own in the /new /cur /tmp directories ??

[Dovecot] Make a whole mailbox read-only
by Sandro Tosi 19 Jul '12

19 Jul '12

Hello, i've found an old thread [1] where it was stated that a whole mailbox can be made read-only only setting the according permissions on the filesystem side. [1] http://www.mailinglistarchive.com/html/dovecot@dovecot.org/2011-12/msg00300… i'd like to check if it's still the only option we have with dovecot v2.0.18 .

Re: [Dovecot] Issues with Plus addressing and detail part of subaddress.

Whilst I would normally agree, at the same time I've had a fair amount of experience with dovecot and sendmail (been running them for over 10 years). Pigeonhole is new to me, however. . . > One thing I did notice is that you are sending this mail from an internal IP... since most people use very different checks for such mail (bypassing many/most checks), maybe you should be testing from an external address (one that comes in from outside your network)? So I have a DMZ that houses the mail server for my domain, which is where the private addresses are. Connections are passed through the OpenBSD router to the mail server. So testing from an external address would be essentially the same (since the connection to the SMTP server talks to the sendmail process as the /usr/lib/sendmail process). Regardless, my original tests were sending mail from the Mac off-network. > Also, it is always recommended when setting up a new server to start with the latest version... for 2.0.x that would be 2.0.19, but the latest is 2.1.8... When I set it up, 2.0.13 _was_ the latest. :-) I was hoping to avoid the pain of recompiling dovecot and pigeonhole. Not that big a deal, I guess. . . >> lda_original_recipient_header = X-Original-To >> lmtp_save_to_detail_mailbox = yes > > Ok, I think this is the problem... > > Dovecot's LMTP currently does NOT preserve the x-original-to header... in fact, brought this up recently (I was one of the ones interested in Timo adding support for it) on this (and the postfix, which is what I use) on this very list: > > http://www.dovecot.org/list/dovecot/2012-April/065075.html > > Apparently, after Timo discussed this on the postfix list, he determined that it would not be a very significant change for him to make to add support for this header in LMTP and that he would get to it sooner than later, but as of now, it has not been added. Actually, I'm not using lmtp. I whacked the lmtp_save_to_detail_mailbox in an effort to see if that was the issue before I realized I don't have it turned on. dovecot.conf has: protocols = imap though in 20-managesieve.conf I have: protocols = $protocols sieve I just turned it off and restarted dovecot (though lmtp was not running) and re-ran the test with the same result. So, I think what's going on is pretty straightforward. The local mailer definition in the sendmail.cf file is: Mlocal, P=/usr/local/libexec/dovecot/dovecot-lda, F=lsDFMAw5:/|@qSPhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u This is more or less right out of the wiki. Since dovecot-lda is passed the -d option, it's using that (and only that) for delivery. Since there's no X-Original-To: header, it doesn't really have any option (since the non-envelope-to address might not exist, or point to something other than the end user's mailbox, etc). It would appear that I have two options: 1) Figure out what macro(s) is(are) valid to pass to dovecot-lda with the -a option in the sendmail config file (sendmail.cf). 2) Get sendmail to put "X-Original-To: <address>" in the header. Both would appear to be a sendmail issue, not a dovecot/pigeonhole issue. Everything I find on the web seems to center around how to use plus addressing to accept mail from multiple email address and filter it into a single address for delivery, only to have the local delivery agent break it back out again. That's not my issue. :-( Sean Sean

[Dovecot] doesn't work at all
by David Drexler 19 Jul '12

Hi, I can't seem to get dovecot to work. When I connect with thunderbird, tbird complains that it can't find the settings for my email. When I connect with evolution, it seems to go through all the motions but it doesn't pick up the waiting messages. Those messages are marked Status: O s if it had read them. The log file for tbird looks like this: Jul 18 17:03:21 why dovecot: imap-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: imap-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: imap-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: pop3-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: pop3-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: pop3-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: imap-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: pop3-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: imap-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: pop3-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 Jul 18 17:03:22 why dovecot: pop3-login: Aborted login (no auth attempts): rip=68.12.110.134, lip=184.176.6.227 The log file with evolution is: Jul 17 19:36:43 why dovecot: imap-login: Login: user=<ddrex>, method=PLAIN, rip=68. 12.110.134, lip=184.176.6.227, mpid=22717, TLS Jul 17 19:36:43 why dovecot: imap(ddrex): Debug: Effective uid=500, gid=500, home=/ home/ddrex Jul 17 19:36:43 why dovecot: imap(ddrex): Debug: fs: root=/home/ddrex/mail, index=, control=, inbox=/var/mail/ddrex Jul 17 19:46:17 why dovecot: imap(ddrex): Error: Next message unexpectedly corrupte d in mbox file /var/mail/ddrex at 1504 My conf file: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.23.1.el6.x86_64 x86_64 CentOS release 6.2 (Final) base_dir = /var/run/dovecot/ imap_client_workarounds = "delay-newmail " listen = * mail_debug = yes mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail mbox_very_dirty_syncs = yes mbox_write_locks = fcntl passdb { driver = pam } pop3_client_workarounds = outlook-no-nuls oe-ns-eoh protocols = imap pop3 service imap-login { vsz_limit = 64 M } service pop3-login { vsz_limit = 64 M } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } -------------------------------------------------------------------- Thanks for any clues. dd

[Dovecot] SQLite dovecot query caching
by Dominic Malolepszy 19 Jul '12

19 Jul '12

Hi, I am wondering if Dovecot caches SQLite queries, and how well it works in high performance setups. I am particularly interested because in the below thread SQLite has been suggested as a means of Dovecot proxying connections to different ports. http://old.nabble.com/director%3A-non-standart-ports-at-backends-td33991991… Cheers, Dominic.

[Dovecot] MySQL dict issues
by list＠airstreamcomm.net 18 Jul '12

18 Jul '12

Testing using the mysql dict for quota storage (dovecot-2.0.12-2_127.el5), and ran into a couple issues. First is a permissions issue: dovecot: lmtp(26786, dude(a)test.tld) Error: net_connect_unix(/var/run/dovecot/dict) failed: Permission denied (euid=5000(<unknown>) egid=5000(<unknown>) missing +r perm: /var/run/dovecot/dict, euid is not dir owner) The file /var/run/dovecot/dict is listed with srw------- perms. I changes the perms to srw----rwx and it works, but I would like to figure out how to configure properly to run with the uid and gid 5000 as this is the user for virtual mail. The second issue is that two identical rows are created in the mysql database for each user quota. The next message delivered updates both rows. Here is my quota config: 90-quota.conf: plugin { quota_rule = *:storage=10G quota_rule2 = Trash:storage=+10% } plugin { quota = dict:user::proxy::userquota } dict { userquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } dovecot-dict-sql.conf.ext: connect = host=a.b.c.d dbname=mail user=user password=derp map { pattern = priv/quota/storage table = domain_user_quotas username_field = username value_field = bytes } map { pattern = priv/quota/messages table = domain_user_quotas username_field = username value_field = message_count } The last issue might be a documentation omission. Dovecot warned me that the mysql user did not have DELETE privileges on the quota table: dovecot: dict: Error: sql dict: commit failed: DELETE command denied to user 'user'@'a.b.c.d' for table 'domain_user_quotas' The quota dict documentation (at http://wiki2.dovecot.org/Quota/Dict) does not mention DELETE being needed: MySQL uses the following queries to update the quota. You need suitable privileges. INSERT INTO table (bytes,username) VALUES ('112497180','foo(a)spam.dom') ON DUPLICATE KEY UPDATE bytes='112497180'; INSERT INTO table (messages,username) VALUES ('1743','foo(a)spam.dom') ON DUPLICATE KEY UPDATE messages='1743'; UPDATE table SET bytes=bytes-14433,messages=messages-2 WHERE username = 'foo(a)spam.dom';

[Dovecot] expire-tool stops on first box with nothing to expire in it
by Michael Wessel 18 Jul '12

18 Jul '12

Hi, I'm running dovecot 1.2.11 on Centos and have the expire plugin enabled. I've had this in place for some time but until now never actually ran the expire-tool. I'm now trying to put this to use. The expire plugin as such is working fine and also the tool is working fine - up to a point. When I run it with --test it goes through a bunch of boxes and lists the messages it would expunge and the new date being logged at the end. As soon as it hits the first box that has nothing in it that's expired however, it stops and goes no further. As an example here are the last two lines of the output when I just ran it: Info: user(a)domain.com/Trash: timestamp 1342320464 (Sat Jul 14 19:47:44 2012) -> 1342937319 (Sat Jul 21 23:08:39 2012) Info: nextuser(a)domain.com/Trash: stop, expire time in future: Sat Jul 14 20:41:49 2012 If I run it again after the indicated expire time it will now also go through the nextuser(a)domain.com but then again stop as soon as it encounters another user with nothing to expire. As far as I can tell the same happens when I actually run the tool. Harder to tell of course as there is no output, but I can tell that not all boxes are expunged as they should be. Any ideas why this would be? Any way to get debug logging on this? Michael

[Dovecot] Compile issue Dovecot 2.1.8, OS X 10.6.x
by Jim 18 Jul '12

18 Jul '12

Hey all. I'm running Mac OS X 10.6.4, and had Dovecot 2.0.7 installed built from source. I'm now wanting to upgrade to Dovecot 2.1.8, but I can't get MAKE to finish without errors: ./configure --with-mysql (snip) Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : kqueue I/O notifys .... : kqueue SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file pam checkpassword sql : -shadow -bsdauth -sia -ldap -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword sql : -ldap -vpopmail -nss SQL drivers .... : mysql : -pgsql -sqlite Full text search : squat : -lucene -solr sudo make (snip) Undefined symbols: "_libiconv_open", referenced from: _charset_to_utf8_begin in libcharset.a(charset-iconv.o) "_libiconv", referenced from: _charset_to_utf8_reset in libcharset.a(charset-iconv.o) _charset_to_utf8 in libcharset.a(charset-iconv.o) "_libiconv_close", referenced from: _charset_to_utf8_end in libcharset.a(charset-iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status make[3]: *** [libdovecot.la] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 The reason for the 'sudo make' was to get around a permissions issue, but I don't think that's related to my issue here. I had build Dovecot 2.0.7 and earlier without issue on this system, but I'm a bit stumped on this particular problem. I also found that the configure parameter --with-sql-drivers no longer seems to work, even though it's still shown in the wiki for 2.x. As far as I can tell, I had used this parameter when compiling 2.0.7.

[Dovecot] Different LDAP filters for different protocols
by James Devine 18 Jul '12

18 Jul '12

Is it possible to query LDAP differently for different protocols? I am using dovecot for both pop3/imap and lmtp deliveries and there are different enable flags in ldap for them. I tried wrapping user_filter inside the protocols in the file dovecot-ldap.conf.ext as shown below but this didn't seem to work. protocol lmtp { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(msmtp=1)) } protocol imap { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(mpop=1)) } protocol pop3 { user_filter = (&(objectClass=posixAccount)(cn=%u)(active=1)(mpop=1)) }

[Dovecot] outlook and redirect sieve
by Lazy 18 Jul '12

18 Jul '12

Hi Aall, we are having issues with outlook clients, running exchange or lotus being unable to parse the email messages redirected by dovecot's sieve 0.3.1, the command is plain redirect "email(a)lotusmail.xxx"; redirects from mta also work correctly exchange was fixed by removing this commit http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-diff/082216ad12d6/src/lib… are there any other modifications to the email body or headers that can make those mesages not parsable for outlook ? looking at http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-diff/082216ad12d6/src/lib… maybe removing HEADER_FILTER_NO_CR fromi_stream_create_header_filter() will make redirected messages more in tact ? what can I do to make redirect more verbatim ? Thanks in advance for any information. Regards, Michal Grzedzicki

[Dovecot] Selective TLS per local IP
by Robert Blayzor 17 Jul '12

17 Jul '12

We have the requirement to provide SSL on some IP addresses, but not others on our servers. Providing SSL is the easy part and we're able to use multiple SSL certificates now. (thanks Timo!) All is working ok, but we several IP hosts that do not require SSL and do not have valid certificates. While we can limit access via a firewall ACL to TLS connect ports (993/995) we can't do so on port 110/143. The problem is that some clients now are smart enough to look for an offered STARTTLS or STLS, and if it's offered, they try to use it. While not normally a problem if your setup for SSL with valid key/certs, if you have a self signed or no CERT at all, it starts connection warnings and errors on the client side. So is there any way possible to turn off advertising of TLS on port or turn it off/on per IP? Something like: ssl = yes ssl_cert = </etc/ssl/cert/default.pem ssl_key = </etc/ssl/cert/default.pem local 10.1.1.1 { protocol imap { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } protocol pop3 { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } } local 10.1.1.2 { ssl = no } *or* ssl = no local 10.1.1.1 { ssl = yes protocol imap { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } protocol pop3 { ssl_cert = </etc/ssl/cert/site1.pem ssl_key = </etc/ssl/cert/site1.pem } } -- Robert Blayzor INOC, LLC rblayzor(a)inoc.net http://www.inoc.net/~rblayzor/

[Dovecot] [PATCH] Interop problem with Cyrus SASL and GSSAPI
by Ben Morrow 17 Jul '12

17 Jul '12

[I sent this a while ago, but it seems not to have made it to the list. I'm resending it having subscribed first; I apologise if anyone get it twice.] I have been trying to get a Postfix mail server using Dovecot SASL to accept GSSAPI AUTH from another Postfix server using Cyrus SASL, and I believe I have found a couple of bugs in Dovecot's GSSAPI implementation. The first problem is that, because of the way the client invokes libsasl, it sends a GSSAPI request which does not ask for mutual authentication. This means that on the server gss_accept_sec_context returns GSS_S_COMPLETE with a zero-length output token. Dovecot currently sends this to the client as a zero-length continuation response, but this is incorrect according to RFC 4752: what it ought to do instead is proceed straight to the security layer negotiations, and send a gss_wrap packet. The second is that Cyrus sends an empty authz identity; that is, the security layer negotiation packet, when gss_unwrapped, is exactly 4 bytes long. Dovecot objects to this, but in RFC 4422 this is explicitly allowed, and means the authz identity is identical to the authn identity. I believe the attached patches (for the 1.2 and 2.1 branches) fix the problem, though I'm not entirely sure if the difference between the p_strndup in mech_gssapi_unwrap and the t_strndup in get_display_name is important.

[Dovecot] Feature request
by Malloc Kilobyte 17 Jul '12

17 Jul '12

Hi, I am implementig Dovecot as a part of my new e-mail server, which is aimed to be replacement for proprietary software I've been using sofar. Appreciating all Dovecot rich features, I lack just one. And this is the ability to customize the "quota exceeded, message rejected" message. I know I can set it's default content using quota_exceeded_message parameter, but i would also like to have ability to set: - to whom the message is sent. Some mail systems send copy not only to the sender, but also to the recipient. It makes sense in case rejected message has big size. - it's subject - if the rejected message is being attached ( with or without it's own attachments ) or not Moreover, I think it would make sense if the "rejected messege" contained information about size of rejected message and current mailbox space usage. Please, consider this in future development. with regards and respect to the tremendousness of Dovecot, -- malloc4k

[Dovecot] doveadm director status username != doveadm director status username@mailserver
by Joseba Torre 17 Jul '12

17 Jul '12

Hi, I've almost finished my new director based setup, but in the first test I discovered that imap and lmtp connections were not always being proxied to the same server. After some research now I think that the main problem is that in imap connections users connect as 'username' while lmtp connections are as 'username@mailserver'. In my current setup I receive mail via SMTP in my director servers (which are loadbalanced by a CISCO machine), and then they send them to dovecot running on localhost. I've tried to get rid of the @mailserver in postfix in a generic way with no success. Is there any way to redirect connections based only in the local part of the address? Or there is a way to get rid of the @mailserver in the postfix -> lmtp connection? Both doveadm config -n and postconf -n are attached.

We don't use passdb in the directors because incoming mails have already been checked by postfix, and the final mail server need to check our ldap server for other values, so we check there.

[Dovecot] imapc: Restrict the number of connections
by René Neumann 17 Jul '12

17 Jul '12

Hi, I have managed to get an imapc connection to another server and bind its contents to only one account (via global ACL). The namespace itself is created as public, though it does not seem to make a difference for this use case (i.e., it does not matter, whether its type is 'public', 'shared', or 'private'). namespace { hidden = no list = children location = imapc: prefix = Gemeinsam. separator = . subscriptions = no type = public } One problem remains: Though there is only one account that is allowed to use this imapc-connection, each imap-process opens a connection to the imapc'd server. Is this caused directly by the imapc_*-definitions in the config? Or is there a way of restricting this to only the account which actually uses it. Used dovecot version: 2.1.8 Thanks, René

[Dovecot] Last login datetime on accounts
by Robert Blayzor 16 Jul '12

16 Jul '12

I have searching for the best way to tell if a Dovecot user is idle by finding the last time they have logged in. Right now the best way I can tell is to do something like "touch" a file in the users homedir via a post login exec. This seems like a LOT of overhead, to accomplish such a simple task, especially if your doing a lot of dozens of logins per second. Is there an easier/better way? Is there a way to possibly tell Dovecot to refresh the mod time on an index file whenever the user successfully auths or to refresh a separate file in the homedir, ie: ~/.lastlogin (not ~/Maildir/.lastlogin as that would obviously cause some issues) Seems like something that would be far less overhead than calling a shell, execing another command, etc. I'm open to other ideas/alternatives if they are out there!

[Dovecot] Multi Server Exim/Dovecot and NFS
by Robert Blayzor 16 Jul '12

16 Jul '12

In reading the Dovecot NFS WIKI entry: http://wiki2.dovecot.org/NFS It mentions a FreeBSD NFS client caching bug. I believe that bug only exists pre-8.x ? It seems that a patch in the PR notes was MFC'd and made it into 8.x at some point. (at least I checked the source in 8.3 and it was there). So I assume that FreeBSD 8.x mitigates the issue? Maybe not? So our deployment is multi server Dovecot/Exim running on FreeBSD servers, frontended by a layer3 load balancing switch and a NetApp NFSv3 datastore. The only real concern we have right now is race conditions and file write contention on the Dovecot index files. Our original plan was to use Dovecot LMTP on the servers to deliver to the inbox, but that doesn't seem to be recommended as we'll have a number of servers all acting as primary MX for domains and delivering to the same set of mailboxes. So are the Dovecot dotlock file locking mechanisms not enough for multiple servers trying to write/access index files in Maildirs? If we have to deliver straight to the ~/Maildir/new out of Exim, that's fine, also. We're just wondering if there is a added benefit of actually using LMTP. (other than making sure the index are kept the most recent). The other concern we have is client mailbox access. While we can make sessions "sticky" from one IP so they hit the same server, it doesn't help with the person that checks their email via POP from their PC while having their mobile phone access it via IMAP. (obviously from different IP addresses). So I guess there is some possibly index file write contention there as well. (though hopefully this should be rare). I'm curious as to know others experiences with a similar deployment. TIA -- Robert Blayzor INOC, LLC rblayzor(a)inoc.net http://www.inoc.net/~rblayzor/

[Dovecot] ACL with MySQL dict => full table scans
by Roland Rosenfeld 16 Jul '12

16 Jul '12

Hi! I'm just installing ACL support on 2.1.6. When a user changes these ACLs, this results in a full table scan on the dictionary, that tells dovecot who shares with whom. Here's what queries I see when I run $ doveadm acl delete -u user1 shared/user2/folder user=user1 1: SELECT dummy,to_user,from_user FROM imap_acl_shares 2: SELECT dummy,from_user FROM imap_acl_anyone 3: BEGIN 4: DELETE FROM imap_acl_shares WHERE to_user = 'user1' AND from_user = 'user1' 5: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user1','user1') ON DUPLICATE KEY UPDATE dummy='1' 6: DELETE FROM imap_acl_shares WHERE to_user = 'user2' AND from_user = 'user1' 7: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user2','user1') ON DUPLICATE KEY UPDATE dummy='1' 8: COMMIT Line 2 is okay, since imap_acl_anyone is always empty (I'm not able to disable this query, otherwise dovecot spawns errors about a missing map, but I can live with this). Don't ask me what lines 4/5 are repeated in 6/7, but these use indexes and I can live with this. But what the hell is line 1? Why doesn't dovecot use a WHERE clause here with either to_user='user1', to_user='user2', from_user='user1', or from_user='user2'? All these WHERE clauses would use an index and speedup the query. Without the WHERE clause I expect 100000 or more results on our production system, which could slow down it massively. Here's my setup: /etc/dovecot/dovecot-dict-sql.conf: connect = host=foo dbname=mail user=imap password=hidden map { pattern = shared/shared-boxes/user/$to/$from table = imap_acl_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = imap_acl_anyone value_field = dummy fields { from_user = $from } } And dovecot -n: # 2.1.6: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_cache_negative_ttl = 5 mins auth_cache_size = 100 M auth_cache_ttl = 5 mins auth_default_realm = example.com auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = always mail_gid = 999 mail_location = maildir:~/mail mail_plugins = acl quota mail_uid = 999 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 imapflags mmap_disable = yes namespace { list = children location = maildir:%%h/mail:INDEX=~/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/passwd.master driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/mail/sieve sieve_extensions = +imapflags } protocols = imap pop3 sieve service auth { unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0600 user = vmail } } service imap { process_limit = 4000 } service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 100 } service pop3 { process_limit = 1000 } shutdown_clients = no ssl = no syslog_facility = local2 userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 10 mail_plugins = quota imap_quota acl imap_acl } protocol pop3 { mail_plugins = quota pop3_no_flag_updates = yes pop3_uidl_format = %v.%u } Tschoeeee Roland

Hi Wojciech Thanks for your comeback.. > maybe - just as in article below > http://www.bishnet.net/tim/blog/tag/maildir-to-mbox/ > you like archive in such format I'm trying to switch dovecot to MBox, not just make archives. BTW: I use http://yergler.net/projects/one-off/maildir-to-mbox as it's much smaller and very simple to use to make archives. Does anyone else know the correct way to either switch the existing Maildir multiple file format to the single MBox file format. Failing that, though it will mean a LOT of work, how do I get dovecot to work in future in MBox single file format. I've entered 'mail_location = mbox:~/mail:INBOX=/%h/%u' in the 'dovecot.conf', but it still saves each message in a file of its own in the /new /cur /tmp directories ?? -------Original question -------- > Can someone guide me on changing the Maildir messages files > back to the single file format I used to have instead of the > dovecot.index /cur /tmp /new format my newer server currently > has.

[Dovecot] director: non standart ports at backends
by Костырев Александр Алексеевич 16 Jul '12

16 Jul '12

hello, I'm trying to figure out how to proxy pop3 and pop3s that listens on non-standart ports at backends. For example, pop3 is at 1110 and pop3s at 1995 (on backend side). is it possible? how should I separate this ports in director's config? it's easy for one port: for example lmtp - you just use passdb in protocol lmtp {}

[Dovecot] Issues with Plus addressing and detail part of subaddress.
by Sean Kamath 16 Jul '12

16 Jul '12

Hi all, So, it's been a while. I'm just ramping back up with Dovecot after a hiatus of a few years. I've been using it fine, complete with Sieve, for about a year, with little or no issues. I finally got around to setting up a second account, to start figuring out how I want to do some plus address filtering. In a nutshell, I want to put mail for foo+bar in foo's 'bar' folder. That's in the wiki. I did this: require ["fileinto", "envelope", "subaddress"]; if header :contains "subject" ["test"] { fileinto "Test"; } if envelope :detail "to" "test" { fileinto "test"; stop; } So, this fails miserably. No error message, nothing in the logs, no nothing. Yet, when I run sieve-test .dovecot.sieve /path/to/testmessage it works just fine. I even run sieve-test -e .dovecot.sieve /path/to/testmessage and it files it just fine into the folder. I tried adding some debug logging, but it looks like vnd.dovecot.debug isn't in my version. I searched the archives, and found a bit about adding (explicitly) the delimiter to the plugin section of 90-sieve.conf. So I did that. I'm running 2.0.13 of dovecot, and pigeonhole 0.2.3 on Solaris 10. Before I dive in and upgrade everything, am I missing something simple? The "test" bit works just fine (and in another account as well), so I think something's just not seeing the detail in subaddressing when mail is delivered (even though it works just fine with sieve-test). Thanks, Sean

[Dovecot] Migrating with dsync and INBOX.INBOX namespace issue
by Nikolai Schupbach 15 Jul '12

15 Jul '12

I'm working on migrating IMAP users from Mirapoint Message Servers to Dovecot servers. The Mirapoint IMAP server uses INBOX as a namespace for private mailboxes. I created the same namespace in Dovecot, but when I migrate mailboxes dsync seems to ignore/miss the namespace on Mirapoint and I end up with all mailboxes under a INBOX.INBOX hierarchy. Mirapoint Source Server ----------------------- * OK server.name Mirapoint IMAP4 3.8.3-GA server ready 1 LOGIN test(a)test.com test 1 OK User logged in 2 NAMESPACE * NAMESPACE (("INBOX." "."))

First, this sub discussion in this thread has been dealing strictly with mechanical storage, and that was intentional. Now you've injected solid state storage, and in the process you first disagreed with my statement, then agreed with it. Apparently you didn't realize you did so.

[Dovecot] recover .sieve plaintext from .sievec binary file
by Florin Andrei 10 Jul '12

10 Jul '12

Hi, I upgraded a server from an old Linux distribution to a much newer one. In the process, Dovecot got upgraded from v1 to v2. By mistake, I deleted the .sieve plaintext file with all the Sieve filters, but I still do have the .sievec compiled binary. Is there any way to dump the binary file back into plaintext format? Keep in mind, I'm running v2 now, and the binary was made on a v1 Dovecot server. Thanks. -- Florin Andrei http://florin.myip.org/

[Dovecot] mailboxes missing after upgrade from 2.1.4 to 2.1.7
by Micah Anderson 09 Jul '12

09 Jul '12

Hi all, I mentioned this on the #dovecot irc channel, but I thought I would post here so I can provide more details. The basic problem is that when I upgraded from 2.1.4 to 2.1.7, some users no longer are able to see their folders in pine/alpine. The folders are actually there, and are subscribed (according to doveadm) and its possible to do operations on those folders, if you know the name (for example, opening the folder works fine if you know the name). When I downgrade to 2.1.4 again, the folders appear again, so its clearly something that changed between the two versions. I looked through the changelog, and found a few possibile culprits, I think pine/alpine use imapc, so that could be related: . imapc: Use imapc_list_prefix also for listing subscriptions . Fixed looking up parent mailbox name with different namespace vs. layout separators. . imapc: Don't list mailboxes that don't match list patterns. . layout=fs: Fixed listing mailboxes with prefix=INBOX/ . LIST with mailbox {} settings incorrectly set subscribed-flags. Here is my dovecot -n output: # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_default_realm = example.net auth_verbose = yes default_process_limit = 256 default_vsz_limit = 512 M dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf quota = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 listen = * login_greeting = howdy, ready. mail_location = mdbox:~/mdbox:INDEX=/srv/dovecot_indexes/%d/%1n/%n mail_plugins = expire quota zlib stats maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . } namespace { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_allow_append_to_spam = yes antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /usr/local/bin/train_spam antispam_pipe_program_args = -d;10.0.1.109 antispam_pipe_program_notspam_arg = ham antispam_pipe_program_spam_arg = spam antispam_pipe_tmpdir = /var/tmp antispam_signature = X-Spam-Flag antispam_signature_missing = error antispam_spam_pattern_ignorecase = SPAM antispam_trash_pattern = trash;Trash;Deleted * expire = Trash expire2 = Trash/* expire3 = Spam expire_dict = proxy::expire quota = dict:Your mail quota::proxy::quota quota_rule = *:bytes=100663296 quota_rule2 = Trash:bytes=+20%% quota_rule3 = Spam:bytes=+10%% quota_rule4 = INBOX.Trash:bytes=+20%% quota_rule5 = INBOX.Spam:bytes=+10%% quota_rule6 = INBOX.restored_from_backups:bytes=+500%% sieve = ~/.dovecot.sieve sieve_after = /var/lib/dovecot/sieve/after.sieve sieve_before = /var/lib/dovecot/sieve/default.sieve sieve_dir = ~/sieve stats_refresh = 30 secs stats_track_cmds = yes zlib_save = gz zlib_save_level = 6 } postmaster_address = postmaster(a)example.net protocols = " imap pop3" service anvil { unix_listener anvil { group = dovecot mode = 0660 user = root } } service auth { unix_listener auth-userdb { group = mail mode = 0600 user = mail } } service dict { unix_listener dict { group = mail mode = 0600 user = mail } } service imap-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service imap-postlogin { executable = script-login /usr/local/sbin/postlogin_imap } service imap { executable = imap imap-postlogin process_limit = 2048 } service pop3-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service pop3-postlogin { executable = script-login /usr/local/sbin/postlogin_pop } service pop3 { executable = pop3 pop3-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = mail } } ssl_cert = </etc/certs/wildcard/cert.pem ssl_cipher_list = HIGH:-ADH:-aNULL ssl_key = </etc/certs/wildcard/key.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol lda { mail_plugins = expire quota zlib stats sieve plugin { quota_exceeded_message = Sorry, your message cannot be delivered to that person because their mailbox is full.

I have Dovecot/Postfix/MySQL/PostfixAdmin, I'd like to setup + sub addressing (for +spam and possibly user-defined +folders) I have setup a user+spam folder path in PostfixAdmin as so; vvv+spam@tld path:tld/vvv@tld/.spam/ that requires me to put a 'duplicate' user with the + and +path for each user, the folks on PostfixAdmin suggested that Dovecot might have a better way of handling this, how do I accomplish this in Dovecot ? thanks for any suggestions or tips -- Voytek
