[Dovecot] postfix/sendmail configuration
by Gary Partis 20 Jul '12

20 Jul '12

Hi all I have searched the net and cant find anything relating to this. In 15-lda.conf, the default sendmail is used to send messges from Dovecot, such as "out of hours" and "redirected" emails controlled by sieves. However, postfix/sendmail is looking in /etc/postfix/main.cf for the configuration file (as logged in /var/log/maillog), but I have the config file elsewhere, and I even have MAIL_CONFIG setup to point to the true config directory. Is there a method of setting 15-lda.conf sendmail config to ensure it uese the correct postfix config file? Thanks in advance Gary

[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?

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 .

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.

[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';
