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

16 Sep '13

Hello, I'm using dovecot v2.0.21. According to http://wiki2.dovecot.org/SSL/DovecotConfiguration,dovecot 2.x supports different SSL certificate for different virtual hosts by using "local_name" directive, but I can't get it to work. When testing the certificate using "openssl s_client -connect domain.com:pop3s" I get the default certificate instead of domain.com's.----------------------------------------------------------------------------Here is the my dovecot.conf:# 2.0.21: /etc/dovecot/dovecot.conf# OS: Linux 2.6.32-358.6.2.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_master_user_separator = *auth_mechanisms = PLAIN LOGINdict { acl = mysql:/etc/dovecot/dovecot-share-folder.conf quotadict = mysql:/etc/dovecot/dovecot-used-quota.conf}first_valid_uid = 2000last_valid_uid = 2000listen = *log_path = /var/log/dovecot.logmail_gid = 2000mail_location = maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/mail_plugins = quotamail_uid = 2000managesieve_notify_capability = mailtomanagesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihavenamespace { inbox = yes location = prefix = separator = / type = private}namespace { list = children location = maildir:/%%Lh/Maildir/:INDEX=/%%Lh/Maildir/Shared/%%u prefix = Shared/%%u/ separator = / subscriptions = yes type = shared}passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql}passdb { args = /etc/dovecot/dovecot-master-users-password driver = passwd-file master = yes}plugin { acl = vfile acl_shared_dict = proxy::acl auth_socket_path = /var/run/dovecot/auth-master autocreate = INBOX autocreate2 = Sent autocreate3 = Trash autocreate4 = Drafts autocreate5 = Junk autosubscribe = INBOX autosubscribe2 = Sent autosubscribe3 = Trash autosubscribe4 = Drafts autosubscribe5 = Junk quota = dict:user::proxy::quotadict quota_rule = *:storage=1G quota_warning = storage=85%% quota-warning 85 %u quota_warning2 = storage=90%% quota-warning 90 %u quota_warning3 = storage=95%% quota-warning 95 %u sieve = /%Lh/sieve/dovecot.sieve sieve_dir = /%Lh/sieve sieve_global_dir = /var/vmail/sieve sieve_global_path = /var/vmail/sieve/dovecot.sieve}protocols = pop3 imap sieveservice auth { unix_listener /var/spool/postfix/dovecot-auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { group = vmail mode = 0666 user = vmail } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail }}service dict { unix_listener dict { group = vmail mode = 0660 user = vmail }}service imap-login { process_limit = 500 service_count = 1}service pop3-login { service_count = 1}service quota-warning { executable = script /usr/local/bin/dovecot-quota-warning.sh unix_listener quota-warning { group = vmail mode = 0660 user = vmail }}ssl = requiredssl_cert = </etc/pki/tls/certs/iRedMail_CA.pemssl_key = </etc/pki/tls/private/iRedMail.keyuserdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql}verbose_ssl = yesprotocol lda { auth_socket_path = /var/run/dovecot/auth-master lda_mailbox_autocreate = yes log_path = /var/log/sieve.log mail_plugins = quota sieve autocreate postmaster_address = root}protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = quota imap_quota autocreate}protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv}local_name nourcc.com { ssl_ca = </etc/ssl/comodo.ca.crt ssl_cert = </etc/pki/tls/certs/nourcc.com.pem ssl_key = </etc/pki/tls/private/nourcc.com.key}local_name rockmetal-ae.com { ssl_ca = </etc/ssl/comodo.ca.crt ssl_cert = </etc/pki/tls/certs/rockmetal-ae.com.pem ssl_key = </etc/pki/tls/private/rockmetal-ae.com.key}local_name alliance-sir.com { ssl_ca = </etc/ssl/comodo.ca.crt ssl_cert = </etc/pki/tls/certs/alliance-sir.com.pem ssl_key = </etc/pki/tls/private/alliance-sir.com.key}----------------------------------------------------------------------------Here are my certs permissions, just in case:[root@epm certs]# ll /etc/ssl/comodo.ca.crt-rw-r--r-- 1 root root 6668 Sep 14 21:51 /etc/ssl/comodo.ca.crt[root@epm certs]# ll /etc/pki/tls/certs/nourcc.com.pem-rw-r--r-- 1 root root 1801 Sep 10 00:00 /etc/pki/tls/certs/nourcc.com.pem[root@epm certs]# ll /etc/pki/tls/private/nourcc.com.key-rw------- 1 root root 1708 Sep 15 19:37 /etc/pki/tls/private/nourcc.com.key----------------------------------------------------------------------------Here is my openssl test output:$ openssl s_client -connect nourcc.com:pop3sCONNECTED(00000003)depth=0 C = SY, O = epm.nourcc.com, OU = IT, CN = epm.nourcc.com, emailAddress = root(a)epm.nourcc.comverify error:num=18:self signed certificateverify return:1depth=0 C = SY, O = epm.nourcc.com, OU = IT, CN = epm.nourcc.com, emailAddress = root(a)epm.nourcc.comverify return:1.......................... blah blah blah ......................... so I'm not sure, is there a certain way for doing it that I overlooked?

[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.

[Dovecot] Unable to use dovecot-antispam plugin

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.

Hi, How can I disable mail delivery to a user or a mailbox temporarily. Is there something in the lines of qmail where you set a sticky bit on the home directory and mail delivery is deferred? Thanks, Avinash.

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

[Dovecot] Antispam plugin / sa-learn
by Mathieu R. 13 Sep '13

13 Sep '13

Hello, Sorry for posting on both list spamassassin and dovecot : my question is on dovecot antispam plugin, used to learn spamassassin with sa-learn. 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

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?

[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.

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?
by Anand Kumria 12 Sep '13

Hi, I am beginning to see many entries like: Sep 10 21:32:06 mail1 dovecot: imap(user1(a)example1.com): Warning: read(/var/run/dovecot/dict): dict lookup took 20 seconds Sep 10 21:32:11 mail1 dovecot: imap(user2(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 25 seconds Sep 10 21:32:16 mail1 dovecot: imap(user3(a)example3.com): Warning: read(/var/run/dovecot/dict): dict lookup took 30 seconds Sep 10 21:32:21 mail1 dovecot: imap(user3(a)example3.com): Error: read(/var/run/dovecot/dict) failed: Timeout after 30 seconds Sep 10 21:32:21 mail1 dovecot: imap(user1(a)example1.com): Warning: read(/var/run/dovecot/dict): dict lookup took 25 seconds Sep 10 21:32:21 mail1 dovecot: imap(user4(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 24 seconds Sep 10 21:32:26 mail1 dovecot: imap(user5(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 29 seconds What is the best way to look into making dict lookups faster? 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

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?

As above the maildir is 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] 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

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.

[Dovecot] best practice to have sent mail folder on dovecot imap server
by Thomas Koch 08 Sep '13

08 Sep '13

I've already asked this here: http://serverfault.com/questions/533940/best-practice-to-have-sent-mail- folder-on-dovecot-imap-server Hi, when I add a mail account to KMail (or most other MUA I suppose) the sent mail folder is on the local machine and I don't have my sent mails on other machines. I'd like to have a sent mail folder in IMAP and I thought that there would already exist a standard or best practice how to set this up so that the mail is only transfered once to the MTA and from the MTA to the IMAP server. I even thought to remember an RFC related to this problem? It isn't that simple, is it? I'm using Exim. Regards, Thomas Koch

[Dovecot] More fine-grained connection limitations?
by Micah Anderson 07 Sep '13

07 Sep '13

There is the mail_max_userip_connections setting, which helps for dealing with number of connections at any given time, but I'm looking for something that will help deal with users who configure their mail clients to connect too frequently. For example, I've seen users who configured their clients to check (IMAP) mail every 3 seconds. This is far too frequent and puts unnecessary load on the server. Even once per minute seems excessive to me. It would be really great if there were a way to tarpit those users to slow them down, or send them an imap message saying they are connecting to often and connections have been disabled for the next 5 minutes or something. Micah ps - what happens to a user when they hit mail_mx_userip_connections? Further connections are just denied, or dropped?

[Dovecot] Plus addressing
by LuKreme 07 Sep '13

07 Sep '13

It appease that I can enable +address filtering into separate mailboxes by simply setting $recipient_delimiter = '+'; However, is there anyway to get great control over that? For example, on one account I have a lot of +addresses I use. A few, I sort into mailboxes (like my bank, credit cards, etc). The rest are either on the “spammer => /dev/null” list or get sorted into a mailbox named “Misc” (like various newsletters and offers and sales from companies I do business with). -- Sigs are b0rk3d.

[Dovecot] Dovecot 2.1.7 not starting properly, mail not delivered
by Aldo & Caroline 07 Sep '13

07 Sep '13

On my debian box dovecot does not start properly any more, and mails don't get delivered or sent. I've googled around without finding any useful leads. Hopefully someone is willing to educate me. My guess is it must be a config problem after an upgrade, since I didn't change anything myself directly. Not sure when it started, since I this mail server is not our default machine (yet). Symptoms Upon /etc/init.d/dovecot restart my command line says [ ok ] Restarting IMAP/POP3 mail server: dovecot.

When starting Dovecot from the command line with dovecot -F -c /etc/dovecot/dovecot.conf nothing is printed (as if the process is waiting for more input), while it should at least produce some output, right?

This process does not seem to kick off when dovecot restarts. Please tell me if I'm thinking in the right direction, and - more importantly - what I need to do to get dovecot running. I will be happy to provide more test results if that helps, just tell me what you need. Regards, Aldo Verlinde

No. The date.saved value is (I think) stored in its indices, and is updated via IMAP operations. This value is not derived from file timestamps. You can use doveadm fetch to get the values that dovecot uses dovecot -ftab fetch -A 'mailbox date.saved' mailbox Junk If you actually use IMAP operations to move messages from INBOX to Junk, I think you'll find that date.saved reflects the correct value.

[Dovecot] userdb with LDAP
by Tobi 06 Sep '13

06 Sep '13

Hi list I currently having troubles to "connect" dovecot (for proxy) to an existing LDAP. If I got the dovecot wiki right only userdb is needed for a proxy setup where the proxy does not authenticate but just forward to the backend for authentication. So I setup the following in dovecot-ldap.conf.ext user_attrs = =password,=y=nopasswd,=y=proxy,mailHost=host user_filter = (&(objectClass=posixAccount)(uid=%u)) There is a field mailHost in LDAP which defines the correct backend for the user and defined userdb in auth-ldap.conf.ext userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } the same config again in auth-system.conf.ext The problem is that dovecot always reports back that the user is unknown. I turned on ldap debug and got the following Sep 6 13:06:10 kolab-frontend dovecot: auth: Debug: ldap(tobi.szyndler(a)datapark.li,213.196.149.1,<88FSBrXlSQDVxJUB>): pass search: base=dc=datapark,dc=li

[Dovecot] doveadm expunge problems
by nicolasfo 06 Sep '13

06 Sep '13

Hello there, I'm trying to use the doveadm expunge function, but it doesn't seems to work.. I have installed a mail test server using iredmail, Dovecot and postfix using mysql for authentications. I sent a email to this server, and change the timestamp using touch. the mail boxes are as follow : /home/mail/vmail1/mydomain.fr/n/i/c/nicolas-2013.09.05.14.30.49/Maildir I want to delete mails that are, let's say, 1day old from the "Junk" folder. (I put the mail I changed the date in it). I run this command : doveadm -Dv expunge -u nicolas(a)mydomain.fr mailbox "Junk" savedbefore 1d The mail is still in the "Junk" folder, and I have this output : root@mail:/home/mail/vmail1# doveadm -Dv expunge -u nicolas(a)mydomain.fr mailbox "Junk" savedbefore 1d doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so doveadm(root): Debug: Skipping module doveadm_zlib_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so: undefined symbol: i_stream_create_deflate (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(nicolas(a)mydomain.fr): Debug: Added userdb setting: plugin/master_user=nicolas(a)mydomain.fr doveadm(nicolas(a)mydomain.fr): Debug: Added userdb setting: plugin/quota_rule=*:bytes=1073741824 doveadm(nicolas(a)mydomain.fr): Debug: Effective uid=2000, gid=2000, home=/home/mail/vmail1/mydomain.fr/n/i/c/nicolas-2013.09.05.14.30.49/ doveadm(nicolas(a)mydomain.fr): Debug: Quota root: name=user backend=dict args=:proxy::quotadict doveadm(nicolas(a)mydomain.fr): Debug: Quota rule: root=user mailbox=* bytes=1073741824 messages=0 doveadm(nicolas(a)mydomain.fr): Debug: Quota warning: bytes=912680550 (85%) messages=0 reverse=no command=quota-warning 85 nicolas(a)mydomain.fr doveadm(nicolas(a)mydomain.fr): Debug: Quota warning: bytes=966367641 (90%) messages=0 reverse=no command=quota-warning 90 nicolas(a)mydomain.fr doveadm(nicolas(a)mydomain.fr): Debug: Quota warning: bytes=1020054732 (95%) messages=0 reverse=no command=quota-warning 95 nicolas(a)mydomain.fr doveadm(nicolas(a)mydomain.fr): Debug: dict quota: user=nicolas(a)mydomain.fr, uri=proxy::quotadict, noenforcing=0 doveadm(nicolas(a)mydomain.fr): Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir://home/mail/vmail1/mydomain.fr/n/i/c/nicolas-2013.09.05.14.30.49//Maildir/:INDEX=//home/mail/vmail1/mydomain.fr/n/i/c/nicolas-2013.09.05.14.30.49//Maildir/ doveadm(nicolas(a)mydomain.fr): Debug: maildir++: root=//home/mail/vmail1/mydomain.fr/n/i/c/nicolas-2013.09.05.14.30.49//Maildir, index=, control=, inbox=//home/mail/vmail1/mydomain.fr/n/i/c/nicolas-2013.09.05.14.30.49//Maildir, alt= doveadm(nicolas(a)mydomain.fr): Debug: Namespace : type=shared, prefix=Shared/%u/, sep=/, inbox=no, hidden=no, list=children, subscriptions=yes location=maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/Shared/%u doveadm(nicolas(a)mydomain.fr): Debug: shared: root=/var/run/dovecot, index=, control=, inbox=, alt= I don't understand, the output seems to be OK, except loading modules at the begining, but I think there's no effect to expunge command...

[Dovecot] stopping dictionary attacks (pop3)
by other＠ahhyes.net 05 Sep '13

05 Sep '13

Hi Guys, I was really hoping a couple of years later this would be addressed... I'm running Dovecot 2.2.5 on FreeBSD. Is there anyway to limit the number of auth attempts allowed in a single session? The reason for this is because I have "fail2ban" setup to firewall out any IP addresses that repeatedly auth fails. The issue occurs when the connection is already in an "established" state and the attacker uses the existing session to hammer away, fail2ban becomes ineffective as dovecot appears to allow the person to attempt authentication ad infinitum. It would be nice if there was config option that would for example cause the software to close the connection after X failed attempts. I use "pf" as the firewall on FreeBSD. Unless there was some command I could have fail2ban run a command that would destroy any tcp sessions in an established state prior to adding the offending IP to the block list, that would be the only way around the problem. Ideally it would be nice for dovecot have an option to control the number of failed auth attempts. Any suggestions? Cheers, Alex.

[Dovecot] Received header only showing localhost
by Matt Devaney 05 Sep '13

05 Sep '13

Hi all, Im a new dovecot user and a first-time poster so please forgive me if this is a stupid question, or even (as I suspect it might be) not really a Dovecot question. My system is the fairly typical mix of postfix, amavis-new, and Dovecot. For some reason Ive noticed that when I look at the mail headers for delivered messages the Received header is missing the detail of any external servers that the mail went through, and additionally the tag appears twice; for example the Welcome to the dovecot mailing list email has: Received: from localhost (localhost [127.0.0.1]) by droplet.the-wyvern.net (Postfix) with ESMTP id DDDD163F73 for <myname(a)mydomain.net>; Mon, 26 Aug 2013 16:40:19 +0000 (UTC) Received: from droplet.the-wyvern.net ([127.0.0.1]) by localhost (droplet.the-wyvern.net [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 6AFMiG0TAHUv for <myname(a)mydomain.net>; Mon, 26 Aug 2013 16:40:17 +0000 (UTC) Searching through the dovecot.markmail archive I can see this doesnt seem to be too unusual in that there are other examples where folk have posted message headers with the above format, however Im wondering if theres a good reason for it and if I can turn it off? I quite like being able to see where my mail came from :) If theres a man / wiki page to read somewhere that explains it then please feel free to tell me to RTM (.. long as you also point me in the right direction :p ) Thanks, Matt

[Dovecot] OT: z-Push
by Christian Rößner 04 Sep '13

04 Sep '13

Hi, just a short question: I have installed and configured z-Push to use BackendIMAP. On my iPhone I have created an account and I can see my mails. Also sending works. So far so good. Now the question: When I create a new folder i.e. Test under the root (/), then I get an error. And after resyncing the folder has been created not under /, but under /0/Test. Also I can not remove that folder over ActiveSync. Does somebody have z-Push fully working with Dovecot or is z-Push designed for Cyrus and only some features are working with Dovecot? So at the moment folder create/move/delete does not work here with z-Push-2.0.3 and Dovecot 2.1.9 Thanks in advance -Christian Rößner --- Bachelor of Science Informatik Erlenwiese 14, 36304 Alsfeld T: +49 6631 78823400, F: +49 6631 78823409, M: +49 176 93118939 USt-IdNr.: DE225643613, http://www.roessner-network-solutions.com

[Dovecot] Dovecot is not creating directories properly for new accounts

Isn't Dovecot supposed to be able to create these?

[Dovecot] dsync - convert plugin missing?
by Regan Yelcich 04 Sep '13

04 Sep '13

I'm looking to convert my mbox mailboxes over to Maildir. But when I try to run the dsync command: (changed with my variables) dsync -u username mirror mbox:~/mail:INBOX=/var/mail/username found on this dovecot v2.X page here: http://wiki2.dovecot.org/Migration/MailFormat I get an error that it can't find the "convert" plugin. Am I doing something wrong? Thanks.

Re: [Dovecot] Deleting messages with Mac Mail via IMAP
by Tim Schneider 04 Sep '13

04 Sep '13

The right wording (expunge) provided me with some clues. Anyway, Mac Mail does not have such a flag. It seems to be deliberately designed to do the expunge on quitting the application. Expunge can also be triggered by using cmd+shift+k with no marked messages to empty all trashes. Using this command, one can also mark a message and expunge it directly, bypassing the trash. I don't want to exclude the possiblity that this has got something to do with the IDLE system, and could be resolved by, for example, providing the right IMAP capabilities flags upon com init. Interestingly, iOS mail does delete the message in the inbox directly when moving it to trash. Thanks anyway to the contributors of this thread, I think I will have to accept this behavior, since Apple does usually not care about customer requests to resolve bugs. Mostly they declare them to be intended stupidity, even when they sell items that behave just the opposite way. Anyway, Zarafa mail server has a flag imap_expunge_on_delete. Perhaps this would be a useful feature for Dovecot to protect admins from angry customers who use well-designed Apple products.

[Dovecot] Deleting messages with Mac Mail via IMAP
by Tim Schneider 03 Sep '13

03 Sep '13

Hello mailing list subscribers! When I delete a message in Mac Mail 6.5 (OS X 10.8.4), with the option to move messages to the trash set in Mac Mail account preferences, the message is copied to the trash, and markes as trashed in the cur/inbox directory on the server (STa flag in the file name). My horde webmail then displays this messages correctly as trashed in the inbox. However, I want the message to be gone from the inbox. Quitting Mac Mail deletes it in the inbox reliably. Is there any IMAP setting for dovecot to get move, and not copy and mark as trashed behavior? Here are my dovecot settings: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.1 ext4 auth_mechanisms = plain login mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = mail 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 passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = admin(a)xxx.xxx protocols = imap pop3 lmtp sieve service auth-worker { user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 995 ssl = yes } } ssl = required ssl_cert = </etc/ssl/certs/mailportabile.pem ssl_key = </etc/ssl/private/mailportabile.key submission_host = localhost userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static } protocol lda { mail_plugins = " sieve" }

Re: [Dovecot] Logging passwords on auth failure/dealing with botnets

Yeah, distributed BFDs are tough to block unless you can characterize the clients well. > That leaves us back to getting dovecot to log the tried password for > unknown users. Another tactic might be to hook in a authentication script: http://wiki2.dovecot.org/AuthDatabase/CheckPassword You can run this as an external plugin and won't have to muck into the dovecot innards. From here, you can log attempts, keep track of bad IPs, or take action if you spot a username/password combination that merits instant blacklisting. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] sync re-copies emails assigning new UIDs
by Anand Kumria 03 Sep '13

03 Sep '13

Hi, I have been (attempting) to transition a company from in-house dovecot 1.x to a hosted dovecot 2.2 setup. I am running the doveadm sync command, and for the four mailboxes have been blocked -- sync'ing seem to be copying the same mails, over and over (note, initially I was using doveadm backup but my reading has indicated that 'doveadm sync' is better) Example: # date && doveadm -v -o imapc_user=kaye(a)example.com -o imapc_password=*pass* -o imapc_host=imap.example.com -o imapc_port=993 -o imapc_ssl=imaps -o imap c_ssl_dir=/etc/ssl -o imapc_feature=rfc822.size -o imapc_ssl_verify=no sync -1 -R -u kaye(a)example.com imapc: Sat Aug 3 09:05:37 UTC 2013 [...] dsync(kaye(a)example.com): Info: copy from INBOX: box=INBOX, uid=5306, msgid=<FB3A2E1C62B148F8B057476BDCBB4A9B@THENORMANS>, size=13544 dsync(kaye(a)example.com): Info: copy from INBOX: box=INBOX, uid=5307, msgid=<006b01ce8dad$b8864930$2992db90$(a)com.au>, size=10163563 [...] dsync(kaye(a)example.com): Info: copy from INBOX: box=INBOX, uid=5311, msgid=< cm.083930.bijjdjk.jdkimlhij.r(a)createsend5.com>, size=46658 [...] # date && doveadm -v -o imapc_user=kaye(a)example.com -o imapc_password=*pass* -o imapc_host=imap.example.com -o imapc_port=993 -o imapc_ssl=imaps -o imapc_ssl_dir=/etc/ssl -o imapc_feature=rfc822.size -o imapc_ssl_verify=no sync -1 -R -u kaye(a)example.com imapc: Sat Aug 3 10:01:48 UTC 2013 [...] dsync(kaye(a)kamdha.com): Info: copy from INBOX: box=INBOX, uid=5324, msgid=<FB3A2E1C62B148F8B057476BDCBB4A9B@THENORMANS>, size=13544 dsync(kaye(a)kamdha.com): Info: copy from INBOX: box=INBOX, uid=5325, msgid=<006b01ce8dad$b8864930$2992db90$(a)com.au>, size=10163563 [...] dsync(kaye(a)kamdha.com): Info: copy from INBOX: box=INBOX, uid=5329, msgid=< cm.083930.bijjdjk.jdkimlhij.r(a)createsend5.com>, size=46658 [...] The exact same number of emails (some in the INBOX, some in the Sent folder) are transferred each time. In this case, I've firewalled the origin - so their entire mail system is stopped whilst I do the transfer just in case modifications of IMAP flags or additional delivieres might have been the problem. I am using Dovecot v2.2.4; is this normal expected behaviour? If so, what is the best way to ensure that a migration is done without data loss. If this isn't expected, has anyone else seen this kind of error before? Thanks, Anand

[Dovecot] setup of dovecot as proxy to dbmail
by Regan Yelcich 03 Sep '13

03 Sep '13

Can anyone point me in the direction of a detailed how-to for setting up a postfix and dovecot (proxy) node with dbmail? In particular I'm looking for a how-to which shows dovecot authenticating against the dbmail database directly. The only example I've found is this one which requires a duplication of the user database. http://content.fens.org/index.php?q=admin-howto/mail/dovecot2dbmail-proxy Thanks.

[Dovecot] Auth error in log
by Per-Henrik Lundblom 03 Sep '13

03 Sep '13

Hi, I have a setup with Dovecot handling a few virtual domains delivering mails to both local Unix account mailboxes and seperate mailboxes for virtual users defined in a MySQL database. A quick overview of the configuration shows two passdb definitions: auth default { mechanisms = plain login passdb pam { args = dovecot } passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { args = mail=maildir:~/Maildir blocking=yes } userdb static { args = uid=vmail gid=mail home=/var/spool/vmail/%d/%n allow_all_users=yes } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail group = mail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } !include_try /etc/dovecot/auth.d/*.auth } When a virtual user defined in the MySQL database tries to log in using IMAP or SMTP I always get auth failures logged in the system logs. Entries are like this: Aug 21 06:25:36 roadrunner dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=luser(a)mydomain.com rhost=85.224.xx.xx I assume these failures comes form the fact that PAM doesn't recognize the virtual users and Dovecot continues to the SQL passdb entry. As a result I get a _lot_ of auth failures in the logs. I have tried to come up with a way where the auth failures from PAM arent't logged if the the SQL authenication is successful. Is this possible or are there any other recommended ways to handle this? /PH -- Per-Henrik Lundblom email: ph(a)whatever.nu phone: +46 733 207126 webpage: www.whatever.nu

[Dovecot] local AND virtual mail locations ?
by Pierre-Philipp Braun 02 Sep '13

02 Sep '13

Hi, I would like to use Dovecot not only for virtual mboxes, but also for local users. In other words, I would like to use different "mail_location"s depending on "passdb" "passwd-file" versus "passwd". I need that as the smtp daemon I am using (david parsons' postoffice smtp server) serves both but is only able to process messages through procmail on local users. Here are the two mail_locations I would like to use: mail_location: mbox:~/mail/:INBOX=/var/mail/%u mail_location: mbox:/var/spool/virtual/%d/%n.imap:INBOX=/var/spool/virtual/%d/%n depending on those passdb stanzas, respectively: passdb passwd-file { args = username_format=%n /etc/virtual/%d/passwd } passdb passwd { } Any help would be appreciated. Here's my Dovecot version and current working configuration for virtual users only: # dovecot -n dovecot -n # 1.2.17: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.3-RELEASE amd64 ufs protocols: imap ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login first_valid_uid: 6 first_valid_gid: 6 mail_location: mbox:/var/spool/virtual/%d/%n.imap:INBOX=/var/spool/virtual/%d/%n imap_client_workarounds: tb-extra-mailbox-sep auth default: user: mail passdb: driver: passwd-file args: username_format=%n /etc/virtual/%d/passwd userdb: driver: static args: uid=6 gid=6 I find that first_valid_uid and first_valid_gid don't look pretty but it seems mandatory for the standard 'mail' user and group ownerships to work on the virtual mbox files and folders. I created the user while the group already existed. If you have any advices on that too, I would be pleased. Thanks Pierre-Philipp
