[Dovecot] feature request: IMAP passdb prefetch
by Richard Platel 02 Aug '13

02 Aug '13

It'd be useful for us if the IMAP passdb could be used as a prefetch userdb. The remote IMAP server could respond with something like * OK key=value * OK key=value SEQ OK [CAPABILITY ...] Logged in. Or * OK <some JSON key value pairs> SEQ OK [CAPABILITY ...] Logged in. Would anyone else find this useful?

> You should take this discussion off list. Tell me Dem.... which part of my original question was not fit for the list ? It was a perfectly valid technical question relating to Dovecot, and according to the description of the mailing list "This is the main list for requesting help with Dovecot or talking about it in general" So I was "requesting help" with Dovecot, and everyone else is perfectly within their rights to "talk about it".

[Dovecot] 2.2.4 - Some questions about and needing help with quota-status
by Axel Luttgens 02 Aug '13

02 Aug '13

Help! I'm stuck. :-( The config of my experimental setup appears at the end of this message; I'm providing hereafter some more info that may not be immediately obvious. This is dovecot 2.2.4 with changesets 9091d0f2d971 and 2be295a0b64f. All involved databases are sqlite ones. passdb and userdb are devised so as to change usernames. For example, I could have a user with addresses "doe(a)oldexample.com", "johnd(a)oldexample.com" and "john.doe(a)example.com" needing to be able to log in as "jdoe" or "u123456"; all db lookups for that user then end with name "john.doe". This is a single mail user setup (user/group "dovemailer", uid/gid 999). Service lmtp has been configured to run as that user; that required a slight adjustment at the auth-userdb socket level. As a general rule, the quota dict appears to be correctly updated upon message arrivals and removals (thru lmtp, pop, imap), and to be correctly queried/interpreted by the various parts of the server. For example, thru the userdb query, user john.doe has been given an even lower quota limit than the already low default defined for testings: $ sudo doveadm quota get -u john.doe Quota name Type Value Limit % Quota utilisateur STORAGE 20 5 400 Quota utilisateur MESSAGE 14 - 0 and is clearly recognized as being over-quota by lmtp: $ telnet /_ROOT/var/run/dovecot/lmtp Trying /_ROOT/var/run/dovecot/lmtp... Connected to (null). Escape character is '^]'. 220 almba.local Dovecot ready. mail from:<mary.jane(a)example.com> 250 2.1.0 OK rcpt to:<john.doe(a)example.com> 250 2.1.5 OK data 354 OK Subject: test . 552 5.2.2 <john.doe(a)example.com> Quota exceeded (mailbox for user is full) Note that both services config and dict are launched if they aren't running. Since it has been previously seen that running quota-status as root comes with its own problems, and since it is a single user setup anyway, I'm trying to run it as dovemailer as well. So, let's try to see what quota-status thinks about john.doe: $ sudo -u _postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. Connection closed by foreign host. Clearly, not much... Looking in the log: dovecot[10554]: quota-status: Fatal: Error reading configuration: net_connect_unix(/_ROOT/var/run/dovecot/config) failed: Permission denied This thus raises a first question: Q1. What makes lmtp and quota-status different? How does lmtp manage to fetch all needed info, while quota-status seems to require an access to the config socket? Let's then slightly adjust dovecot.conf, in the hope to make quota-status happy: service config { unix_listener config { group = dovemailer mode = 0660 } } Q2. Should the above really be needed, wouldn't there be a better way? I ask, because it seems to me that I'm starting to seriously lose the benefits of privilege separation... Anyway, let's ask quota-status again: $ sudo -u _postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Password: Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. recipient=john.doe(a)example.com size=10000 action=OK ^] telnet> quit Connection closed. In the log: dovecot[11050]: auth: Debug: userdb out: USER 1 john.doe(a)example.com quota_rule=*:storage=5k dovecot[11050]: quota-status: Debug: auth input: john.doe(a)example.com quota_rule=*:storage=5k dovecot[11050]: quota-status: Debug: Added userdb setting: plugin/quota_rule=*:storage=5k dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Effective uid=999, gid=999, home=/_Mailstores/john.doe dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota root: name=Quota utilisateur backend=dict args=john.doe:proxy::sql_quota dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota rule: root=Quota utilisateur mailbox=* bytes=5120 messages=0 dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota grace: root=Quota utilisateur bytes=512 (10%) dovecot[11050]: quota-status(john.doe(a)example.com): Debug: dict quota: user=john.doe, uri=proxy::sql_quota, noenforcing=0 dovecot[11050]: quota-status(john.doe(a)example.com): Debug: fs: root=/_Mailstores/john.doe/mboxes, index=, indexpvt=, control=, inbox=/_Mailstores/john.doe/mboxes/inbox, alt= It is to be noted that the config server is now launched as expected, but that the dict server still isn't. Trying a dirsize backend instead of the dict backend doesn't help. The problem seems to be circumscribed to the interaction with the quota backend since, for example, querying quota-status for an unknown recipient yields an expected "action=REJECT Unknown user". Hence my last question, after having tried a lot of things for several days now, with no more success: Q3. What am I doing wrong?

[Dovecot] mails delivered to the wrong user when using lmtp_proxy and reject_unverified_recipient
by Peer Heinlein 02 Aug '13

02 Aug '13

Hi, looks like we detected a serious bug in dovecot's lmtp proxying where e-mails are delivered to the wrong user. The setup is: *) Dovecot is configured with "lmtp_proxy=yes" # Support proxying to other LMTP/SMTP servers by performing passdb lookups. lmtp_proxy = yes *) Postfix uses "dynamic recipient verification", so Postfix starts sending a (verify) mail by LMTP to dovecot, but quits the lmtp-session right after the RCPT TO:. No DATA-stage is reached in the protocol and no real e-mail is sent. But Postfix had a LMTP-connection for "user1". *) Just some seconds later a "real" e-mail to "user2" has to be delivered to dovecot by LMTP. But Dovecot will deliver this mail to the wrong "user1" instead of "user2". Looks like dovecot re-uses the (still opened?) lmtp-proxy-connection from "user1" to deliver an e-mail to "user2". Have a log at the protocol: 1) There's a verify call to user1 from Postfix: Jul 19 13:49:49 mailms postfix/lmtp[9842]: DE653280C51: to=<user1(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=2, delay=120, delays=117/0.45/0/2.5, dsn=2.1.5, status=deliverable (250 2.1.5 OK) 2) Just five seconds later the e-mail to user2 (see Postfix' point of view in the last line) is delivered to user2 (see result from Dovecot in the last line): Jul 19 13:50:04 mailms dovecot: lmtp(10965, kraemer): save: box=INBOX, uid=49880, msgid=<59798276-E5D1-4053-A570-9901B731DF5D(a)example.come>, size=11020 Jul 19 13:50:04 mailms dovecot: lmtp(10965, kraemer): 1zTeKrMn6VHVKgAAhyqEuA: msgid=<59798276-E5D1-4053-A570-9901B731DF5D(a)example.com>: saved mail to INBOX Jul 19 13:50:04 mailms postfix/lmtp[10953]: C25FC280BE5: to=<user2(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=19, delay=116, delays=115/0.53/0/0.33, dsn=2.0.0, status=sent (250 2.0.0 <user2> 1zTeKrMn6VHVKgAAhyqEuA Saved) Same with user3 and user4: Jul 19 14:47:53 mailms postfix/lmtp[10845]: C389A2809D7: to=<user3(a)example.com>, relay=localhost[127.0.0.1]:24, delay=4.7, delays=3.7/0.87/0/0.19, dsn=2.1.5, status=deliverable (250 2.1.5 OK) Jul 19 14:47:55 mailms dovecot: lmtp(26546, fs211113): save: box=INBOX, uid=8504, msgid=<928729810.113.1374238063381(a)example.com>, size=233151 Jul 19 14:47:55 mailms dovecot: lmtp(26546, fs211113): MbMvI2816VGyZwAAhyqEuA: msgid=<928729810.113.1374238063381(a)example.com>: saved mail to INBOX Jul 19 14:47:55 mailms postfix/lmtp[22524]: 6F0D2280A6E: to=<user4(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=2, delay=10, delays=8.4/1/0/0.8, dsn=2.0.0, status=sent (250 2.0.0 <user3> MbMvI2816VGyZwAAhyqEuA Saved) The user itself is quite normal in the user database (but has a mailhost=127.0.0.1 set): root@mailms:/etc/dovecot/conf.d# doveadm user user2(a)example.com userdb: user2(a)example.com uid : 5000 gid : 5000 home : /srv/mail/user2 root@mailms:/etc/dovecot/conf.d# doveadm auth user2(a)example.com Password: passdb: user2(a)example.com auth failed extra fields: user=user2 Peer -- Heinlein Support GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-42 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Auth-woker log lines
by Grzegorz Staniak 02 Aug '13

02 Aug '13

Hi, Are log lines like the following: Jul 28 15:30:50 mx1.somewhere dovecot: auth-worker(18980): sql(user(a)domain,217.67.x.x): unknown user Jul 28 15:32:56 mx1.somewhere dovecot: auth-worker(18980): sql(user(a)domain,212.182.x.x): Password mismatch written every time any authetntication phase fails, in SASL as well as in POP3/IMAP mailbox access? I have a legacy app that would gain a lot if I could distinguish between failed SASL authentication and failed POP3/IMAP authentication. I know I can use the "auth failed" lines for the latter case, and postfix log lines in the former, but they don't contain user info. Is there a way for log monitoring software to get failed login lines with both user info, and the reason (SASL, POP3, IMAP)? Regards, -- Grzegorz Staniak <gstaniak [at] gmail _dot_ com>

[Dovecot] 2.2.4 - quota-status changing the user it is running as
by Axel Luttgens 02 Aug '13

02 Aug '13

Hello, I'm currently experimenting with this quota-status service configuration: service quota-status { client_limit = 1 executable = quota-status -p postfix # Let's make the default explicit. user = root unix_listener /var/spool/postfix/private/quota-policyd { user = postfix } } The idea is to run the service as root during the preliminary tests (at worst, since the service is going to be used as a policy daemon by Postfix only, it shouldn't be very problematic to have it running as root anyway). A user, with address john.doe(a)example.com and identified as john.doe, is known to be over-quota. A "doveadm quota get" returns: $ sudo doveadm quota get -u john.doe Password: Quota name Type Value Limit % Quota utilisateur STORAGE 5 5 100 Quota utilisateur MESSAGE 9 - 0 and messages for that user are correctly rejected by lmtp: dovecot[4989]: lmtp(5069, john.doe(a)example.com) QWSWLgrP4lF7FAAA5Q0ykw: msgid=<20130714161643.9085DF176F2(a)ALMba.local>: save failed to INBOX: Quota exceeded (mailbox for user is full) Let's now simulate a connection from Postfix: $ sudo -u postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. A look at the output of top (excerpt) confirms that quota-status is running as root: PID COMMAND UID 5100 quota-status 0 Going on with our telnet session: recipient=john.doe(a)example.com size=10000 action=OK Hmmm... OK, this may be a config problem of mine which may require further investigation. Anyway, looking at top's output: PID COMMAND UID 5100 quota-status 999 it appears that quota-status is now running as the mail_uid/mail_gid user; the switch happens immediately after having entered the empty line in the telnet session. Let's then try to go further within the telnet session: recipient=john.doe(a)example.com size=10000 action=DEFER_IF_PERMIT Internal error occurred. Refer to server log for more information. ^] telnet> quit Connection closed. and a look at the log indeed reveals that quota-status doesn't have sufficient privileges anymore: dovecot[4989]: quota-status(john.doe(a)example.com): Error: user john.doe(a)example.com: Error reading configuration: net_connect_unix(/_ROOT/var/run/dovecot/config) failed: Permission denied Is this the expected behavior, to have quota-status switch to another user? TIA, Axel

[Dovecot] [PATCH] quota-status: allow different action for messages that are too large (over maximum quota)
by Ulrich Zehl 02 Aug '13

02 Aug '13

This proposed patch to quota-status allows the administrator to return different actions for messages that (a) cannot currently fit in the quota (because there's not enough free space) and (b) are over the maximum quota limit (and could not even be delivered if the mailbox was empty). Configuration works like this: plugin { quota_status_overquota = DEFER_IF_PERMIT 4.2.2 Mailbox full quota_status_toolarge = REJECT 5.2.3 Message length exceeds administrative limit } The patch is backwards compatible: If quota_status_toolarge is not set, quota_status_overquota is returned. No changes are necessary in setups where the new feature is not desired. The reason I developed this patch is: In my environment, I have mostly POP3 mailboxes, where condition (a) changes frequently (usually after each login), but condition (b) will almost never change (users do not get additional mailbox space often). Thus, I'd like to avoid bouncing mails that could be delivered half an hour later. This patch works for 2.2 and 2.1. (This assumes you have already applied the trivial patch I sent earlier; otherwise patch(1) will report some fuzz.) What do you think of this?

[Dovecot] misconception in uid and gid
by Felix Rubio Dalmau 02 Aug '13

02 Aug '13

Hi, I'm using a SQL database to store the usernames and passwords of my users. However, I have found that I must explicitly return the uid and gid with every query, even though all virtual users use the same uid and gid. The query, that works, is: user_query = SELECT mail, 'vmail' AS uid, 'vmail' AS gid, home, CONCAT('*:storage=', quota_MB*1024) AS quota_rule \ FROM virtual_users AS V LEFT JOIN virtual_domains AS D ON V.domain_id=D.id WHERE V.user='%n' AND D.name='%d' Nevertheless, if I remove the segments "'vmail' AS uid, 'vmail' AS gid" and modify the file conf.d/10-mail.conf to show mail_uid = vmail mail_gid = vmail I get this error: dovecot: auth: Error: userdb(<mail>): client doesn't have lookup permissions for this user: userdb reply doesn't contain uid (change userdb socket permissions) Does anybody know what is wrong in my set-up?

Hello Axel, but then I don't get it: I thought that "uid" and "gid" in the user_query where used to access the local FS, whereas the "unix_listener auth-userdb" are used to indicate under which owner/group must be auth-userdb run... although maybe I'm wrong :-S :-) What I'm looking forward to is to eliminate the need for returning these two fixed items, as long as all the virtual_users will be using the same uid and gid.

[Dovecot] Wrong remote IP (rip) in mail.log using IMAP login
by tyli 02 Aug '13

02 Aug '13

Dear list users While trying to secure our dovecot server with fail2ban I came across the following problem: We use dovecot (1.2.9, ubuntu package) behind a NAT, and failed login attempts are logged with our firewall as the remote ip. Example: Apr 15 08:36:26 mail dovecot: imap-login: Disconnected (auth failed, 6 attempts): user=<xy>, method=PLAIN, rip=192.168.0.1, lip=192.168.0.3 Therefore I would ban 192.168.0.1 which means that I ban EVERY user. Funny thing is that POP3 login attempts are logged correctly: Apr 13 11:05:50 mail dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<sgvyniwx>, method=PLAIN, rip=217.81.27.55, lip=192.168.0.3 Any ideas how to change this? Thanks in advance tyli

[Dovecot] trouble with setting individual quota values for multiple namespaces
by Andreas Oster 01 Aug '13

01 Aug '13

Hello all please apologize that I repost this problem again. I tried to get some help several times on the list but did not find/get a solution. I am still struggling to setup different quotas for namespaces. In addition to the default "INBOX" namespace I have created a namespace called "MailArchive" which should have its own quota value of 5G per user. At first I configured quota2 like this: quota2 = maildir:MailArchive quota:ns=MailArchive/ quota2_rule = *:storage=5G and this seemd to work quite well. Users, accessing the MailArchive namespace can see the 5G limit in their mail client, unfortunately in the mail.err log file, errors like these repeatedly appear: Jul 29 11:40:24 mailserver dovecot: imap(testuser): Error: quota: Unknown namespace: MailArchive/ Jul 29 11:41:43 dovecot: last message repeated 47 times In the WIKI I have read, that in order to have quota for different namespaces, one would have to use different quota backends so I changed the quota config for the MailArchive namespace to SQL. namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = mailbox Drafts { auto = subscribe driver = special_use = \Drafts } mailbox Junk { auto = subscribe driver = special_use = \Junk } mailbox Sent { auto = subscribe driver = special_use = \Sent } mailbox "Sent Messages" { auto = no driver = special_use = \Sent } mailbox Trash { auto = subscribe driver = special_use = \Trash } prefix = separator = / subscriptions = yes type = private } namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = yes location = maildir:/var/vmail/archive/%Ln/Maildir mailbox "Archived Mails" { auto = subscribe driver = } prefix = MailArchive/ separator = / subscriptions = yes type = private } plugin { quota = maildir:User quota:ns= quota2 = dict:Archive Quota:%u.mailarchive:ns=MailArchive/:proxy::sqlquota quota2_rule = *:storage=5G quota_rule = *:storage=1G quota_rule2 = Trash:storage=+200M } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } Unfortunately this did not change anything. Quota is working like expected but I still get the same errors in mail.err. I am currently using dovecot version 2.2.4. Thank you for your kind help best regards Andreas

I think the cause is clear enough: you (user=md5i/uid=1000) are not part of group mail (gid=8), so the dovecot user process doing things on your behalf cannot create index files that are anlogous to the mailbox it's indexing. You can either 1) add "md5i" to group mail 2) remove g+w permission on your mail files (making group membership irrelevant) 3) fiddle with "mail_privileged_group = mail", but I'm a little hazy on all the ramifications of this. I don't know your particular circumstances, so I don't know which is best. If (big if) nothing on your system (particularly the MTA) requires access to your mail spool files by running as group=mail, probably 2) is your best option. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] LMTP: userdb lookup - user-filter with variables
by Burckhard Schmidt 31 Jul '13

31 Jul '13

I tried to use dovcots lmtp instead of dovecot-lda. postfix has in master.cf ... dovecot-lda -f ... -d ${user} to separate the user part from user(a)hostname.domain. So lookup of "user" succeeds in userdb (LDAP) done by dovecot-lda. I have always local addresses like to=<user(a)hostname.domain> postfix/lmtp[6579]: [ID 197553 mail.info] B3CDA66A16: to=<h0094slk(a)mailstore4.hu-berlin.de> With lmtp the userpart must be separated also. I tried user_filter (LDAP) with %n, %Ln, %8n without success: userdb lookup: user(a)hostname.domain doesn't exist) dovecot-2.1.17 I used "doveadm user h0094slk" and "doveadm user h0094slk(a)mailstore4.hu-berlin.de" for my tests. userdb { driver = ldap args = /usr/dovecot/etc/ldapuser.conf } and ldapuser.conf with ... user_filter = (&(uid=%n) (objectClass=cmsAccount)) user_attrs = homeDirectory=home I modified user_filter like uid=%Ln or uid=%8u success for doveadm user h0094slk (because nothing to split) userdb: h0094slk home : /home/p0094/h0094slk but no success for doveadm user h0094slk(a)mailstore4.hu-berlin.de userdb lookup: user h0094slk(a)mailstore4.hu-berlin.de doesn't exist It looks for me like user_filter do not use variables at this point?

"Hogging" CPU and memory is putting it strongly, as it is basically suspended while blocked on waiting for a connection, and if left for a long time in an idle state, might be swapped out to disk and not consuming (real) memory, or consuming real memory that isn't in use otherwise. As I stated before, the resource usage is small compared with all the other stuff going on, so if you don't have a busy mail server, I don't think you should sweat the difference. The benefits of LMTP should increase with load, as having LMTP resident will save you the overhead of repeatedly loading/unloading LDA, and I'm sure the CPU and memory usage of servicing that overhead will be non-trivial. If you have oodles of memory, then it's no problem keeping a LMTP resident. If you don't have enough memory and are VM disk thrashing, you'll have other problems and LDA/LMTP is the least of your worries. > And when it's running as root there is always the danger > of privilege escalation. LDA only runs when it's needed and since it > uses only user rights it shoudbe more harmless. I didn't contest the privilege separation aspect, as it a necessary design trade-off that one daemon doing things for all user will need overriding access. However, if this is a concern, you can virtualize all your users. LMTP can theoretically be subverted, but at least won't be as root. (I'm assuming LMTP stays as root, and not spawning off user processes to do the real work.) Joseph Tam <jtam.home(a)gmail.com>

Well, the background process is hogging CPU and RAM while it basically does nothing. And when it's running as root there is always the danger of privilege escalation.

[Dovecot] LDA vs. LMTP
by Martin Burgraf 30 Jul '13

30 Jul '13

Hi there, I'm using Dovecot together with Postfix; as I understand it, there are two ways to transfer the mail from Postfix to Dovecot. 1.) by using LDA with mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" 2.) by using LMTP with mailbox_transport = lmtp:unix:private/dovecot-lmtp (currently using number 1) I'm interessted in the differences and the advantages/disadvantages of each of those solutions. According to http://wiki2.dovecot.org/LDA the recommended way is to use LMTP, since it's supposed to have a better performance. On the other hand, http://wiki2.dovecot.org/LMTP says, that LMTP is a backgound process, while LDA is only called when needed. I've also read, that LDA only uses the users privileges, which both means, that LDA should be better. I've also noticed, that LMTP adds an additional Recieved:-Header to the mail. Are there any other differences? Thank you M.

[Dovecot] Maildir permissions and Solr re-indexing
by Michael Welsh Duggan 29 Jul '13

29 Jul '13

I am running a very small dovecot installation with only one user (me). I use the Solr indexer for indexing. Due to complicated reasons, I was forced to remove all the indexes and need to re-index everything. All the files in my Maildir are owned by md5i:mail (I am md5i), and have 660 permissions. All directories have the same user:group permissions, and 770 with the setguid bit set. (That last may not be necessary, but I was trying several things to get my use case to work.) Unfortunately, I can't seem to get re-indexing to work. When I do "doveadm fts rescan -A" as root, I get the following error for each of my subgroups: doveadm(md5i): Error: fchown(/home/md5i/Maildir/.mail.test/dovecot.index.log.newlock, group=8(mail)) failed: Operation not permitted (egid=1000(md5i), group based on /home/md5i/Maildir/.mail.test - see http://wiki2.dovecot.org/Errors/ChgrpNoPerm) After this, each directory has a dovecot.index.log with md5i:md5i 600 permissions. I've read the mentioned page, and played around with the ideas on it, but haven't gotten things to work. Anyone have any clue to ship my way? -- Michael Welsh Duggan (md5i(a)md5i.com)

[Dovecot] Upgrading to dovecot2 broke IDLE on one mailer, but not another
by John Stracke 29 Jul '13

29 Jul '13

Last weekend I upgraded my server (complete reinstall, actually), from Debian sarge to wheezy, which brought me from dovecot 1.x (I think) to 2.1.7. It's all working now, *except* that the MUA I use on Android, Kaiten (a fork of K-9), apparently no longer gets IDLE notifications. Before the upgrade, when mail arrived, Kaiten would pop up an Android notification immediately; now, it never does (or it might, hours later, with all the messages it notices at that time--presumably this happens when its background service gets killed off and restarted). The weird thing is that IDLE still works flawlessly with Thunderbird, which suggests this is a protocol interaction between Dovecot 2 and Kaiten. (I plan to check with the Kaiten folks next.) Has anybody here seen this? Is there something I can turn on in Dovecot to help debug it? I did check my old Dovecot settings, and they didn't specify anything non-default about IDLE. Thanks in advance!

[Dovecot] how to setup different quota for multiple namespaces
by Andreas Oster 29 Jul '13

29 Jul '13

Hello all, I am using dovecot for some time now but always had very basic configurations. I recently have configured a new, additional namespace in order to move archived mails (Thunderbird Archives) to another storage system. namespace { type = private separator = . prefix = Archives. location = maildir:/var/vmail/archive/%Ln/Maildir subscriptions = yes list = children inbox = no } This works well but unfortunately I cannot find a solution to either ignore this new namespace from quota computation or add a separate quota value for it. I have integrated user authentication with LDAP and fetch some user attributes from LDAP entries: user_attrs = =home=/var/vmail/%Ln/Maildir,=mail=maildir:/var/vmail/%Ln/Maildir/,otherPager=quota_rule=*:storage=%$ I configured the quota plugin in the following way: plugin { quota = maildir:User quota:ns= quota2 = maildir:Archive quota:ns=Archives. quota_rule = *:storage=1G quota_rule2 = ns=Archives.:ignore } unfortunately this does not give the desired result. Folders under the Archives namespace use the same quota as INBOX. Does anyone have an idea how to fix this ? Thank you for your kind help Andreas

[Dovecot] Case-insensitive "detail" mailboxes?
by /dev/rob0 27 Jul '13

27 Jul '13

We're using sieve with LMTP. We want to have lda_mailbox_autocreate and lmtp_save_to_detail_mailbox. Is there a way to make the "detail" case-insensitive? If so I have not found it yet. I suppose we could lowercase the input string for the SQL userdb query, but that's not what is wanted. The idea being that if a user makes a mailbox called "Test" is that user+test(a)example.com and user+TEST(a)example.com should both go to that "Test" mailbox. If it was lowercased, a mailbox called "Test" would be ignored and "test" used. With autocreate, this could be a problem if mail is delivered to autocreated case-sensitive mailboxes that the user won't see. Hmmm, maybe a global sieve script? -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

[Dovecot] dbus support in dovecot?
by Gene Heskett 27 Jul '13

27 Jul '13

Greetings; I am trying to transition from ubu10.04.4 LTS to ubu12.04.2 LTS, but in the changeover I want to setup dovecot as a local only imap server so that I can read & respond to email from any of the other 4 or so machines on my local net. To that end, and given that I have a well working setup right now, using fetchmail driving mailfilter as a pre-check, procmail as the MTA delivering to /var/spool/mail/me, with clamav and spamd in the mix to intercept and send to /dev/null the worst of the spam, or to a quarantine file if clamav triggers. The current transfer mechanism is driven by a script that uses inotifywait to detect newly delivered mail in that directory, and which then sends kmail a dbus message to go get the mail. Since I want to insert dovecot into this chain, does dovecot have a dbus port, and if so, what is the format of the command it expects? Thanks all.

[Dovecot] Namespace, Sieve and upgrading to dovecot 2.0 -- no folder "INBOX/"
by Ben 27 Jul '13

27 Jul '13

I just upgraded from debian squeeze->wheezy. This meant upgrading from dovecot 1.2 to 2.1.7 and upgrading to Pigdeonhole sieve. I have dovecot configured to use sieve and virtual users (I'll post config below) Now any message that come in get filtered by sieve, but any messages that don't hit any filters gives the error (in the sieve log): msgid=<XXXX(a)XXX.com>: failed to store into mailbox 'INBOX/': Invalid mailbox name As far as I can tell, Pidgeonhole has hard-coded to the behavior of 'keep' (that is unfiltered emails) to be: fileinto "INBOX/" However, in my setup "INBOX/" is not a valid folder. "INBOX" is. Is there a way to get pidgeonhole sieve to treat 'keep' as fileinto "INBOX"? Or do I need to reconfigure my dovecot namespaces? I tried playing with them, but everything works right now (sharing, etc) and when I changed my prefix on the inbox, etc, it did weird things (INBOX.INBOX.FOLDER) instead of (INBOX.Folder). Suggestions? Here is, I believe the relevant config info: dovecot.conf: namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/Mail/Users/%%n/:INDEX=/Mail/Users/%u/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } Thanks, Ben

[Dovecot] dovecot-lda not logging if dovecot runs under daemontools
by Roberto Puzzanghera 26 Jul '13

26 Jul '13

Hello all, I have dovecot running under daemontools and I can't see dovecot-lda in action when I read the logs. I've set the logs to /dev/stderr because daemontools redirects /dev/stderr to /var/log/dovecot/current. The dovecot server works fine and I know that dovecot-lda is actually doing the delivery, because the sieve facility is working as well. I can get lda log working -but only on syslog- if I override the log_path in this way: protocol lda { mail_plugins = $mail_plugins sieve log_path = } I'm calling dovecot-lda in the usual qmail way. This is my .qmail-default: |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $EXT@$USER As running dovecot under daemontools seems to be a common practice among qmail users, could any of you give me an hint on how dovecot should be configured to achieve the purpose?

[Dovecot] Managing IMAP IDLE/Push with Sieve – possible?
by FF 25 Jul '13

25 Jul '13

Hello, I've been using Dovecot with Sieve for a long time already, and I'm very happy with it. Push is working fine too. I was wondering, however, whether it would be possible to define a Sieve rule (perhaps using some plug-in), such that an IMAP push message gets sent out only for specific senders etc.? Have you come across anything like that? Thanks a lot, F.F.

I have been trying off and on for the better part of a year to get a dovecot server migrated from one machine to another. It is currently working on CENTOS and we are trying to get it on Redhat. Currently I have everything migrated and working in IMAP, but we have one client device that requires POP3 (doesn't support IMAP). To this end, we have set up everything to work in POP3 as far as I can tell. In the dovecot.conf file, we show: protocols = imap imaps pop3 pop3s protocol pop3 { pop3_uidl_format = %08Xu%08Xv } The services running include: dovecot-auth imap-login imap-login imap-login pop3-login pop3-login pop3-login Everything else looks good including the logs which seem to show proper connectivity - messages are being received, accounts are connecting and disconnecting, etc. but the pop connections are not (apparently) passing messages found in that box. They are still just sitting there, not being read, picked up, or otherwise delivered by dovecot. Any ideas on what else I can check or change to get this to pick up? Thanks, Tom Higgins

[Dovecot] zlib error when running doveadm
by Michael Long 22 Jul '13

22 Jul '13

I manually fixed it by copying src/plugins/zlib/lib20_zlib_plugin.la to /usr/local/lib/dovecot/doveadm I do not understand why 'make install' won't do that? A bug perhaps?

I took a look in the directory /usr/local/lib/dovecot/doveadm/ and it appears the upgrade rebuilt all libraries EXCEPT zlib.

[Dovecot] OT: SAN vs Flash only SAN-less VM architecture for data storage
by Charles Marcus 21 Jul '13

21 Jul '13

Hello all, I am investigating options for leveraging our companies two locations, to provide fault tolerance/redundancy for our VM infrastructure. I was looking at SAN storage options, but ran across an interesting article, and would like opinions. It sounds great, a real win-win as to cost *and* performance... We have redundant/identical hosts at each location that can fulfill the requirements discussed... http://www.storage-switzerland.com/Articles/Entries/2012/9/20_The_Benefits_… or http://tinyurl.com/khwuspo Stan, I'm especially interested in your take, considering your experience with high end SANs and VM storage environments... Thanks, -- Best regards, Charles

The pointer on the v1 wiki pointed to a non-existent page http://wiki2.dovecot.org/ is for version >= 2.0 many configs are completly different in v2 http://wiki.dovecot.org/ This documentation is for Dovecot v1.x, see wiki2 for v2.0 documentation
