[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 .

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

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.

[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

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
