by Joy 25 Mar '16

25 Mar '16

Hi guys, We have implement imap idle in web mail built by us to have push mail feature. IMAP idle working perfectly with browser notification and we are happy with it but having one issue with users who close the browser directly and never logout in that case there are number of idle connection which are not in use and users are unable to login once IP wise connection limit is reached. Dovecot is not closing connection which are not in use, is there any setting available which can help me to resolve this issue.

Trouble handling encrypted passwords
by Dan Wilson 25 Mar '16

25 Mar '16

I am running into trouble when I try to use encrypted passwords. I set my dovecot 2.2.10-5 installation back to plain text passwords and was then able to login and retrieve emails. When I set the default_pass_scheme to MD5-CRYPT in my sql config file, and store an MD5-CRYPT password in the sql database, I invariably get password mismatch errors on login: Mar 24 19:40:30 server1 dovecot: auth: Debug: client in: AUTH#0113#011PLAIN#011service=imap#011secured#011session=25HcztQuwQBHCDBi#011lip=xx.x.xx.xxx#011rip=71.8.48.98#011lport=993#011rport=60609#011resp=<hidden> Mar 24 19:40:34 server1 dovecot: auth-worker(9443): Debug: sql(test1(a)xxxxxx.com,xx.x.xx.xx): query: SELECT email as user, password FROM virtual_users WHERE email='test1(a)xxxxxx.com'; Mar 24 19:40:34 server1 dovecot: auth-worker(9443): sql(test1(a)xxxxxx,xx.x.xx.xx): Password mismatch Mar 24 19:40:36 server1 dovecot: auth: Debug: client passdb out: FAIL#0113#011user=test1(a)xxxxxx.com The password in the database was created using doveadm pw command and is stored as: {MD5-CRYPT}$1$5QAeG70c$dP8y7XJVd.VxZBF/DvcAa0 I tried removing the {MD5-CRYPT} from the password string, but that didn't help. I have to be doing something stupid because this should just work! Any ideas from anyone? Thanks much, Dan

Replication issues master <-> master nfs backend
by William L. Thomson Jr. 24 Mar '16

24 Mar '16

I keep having some replication issues and not sure what can be done to resolve or correct. It does not seem to happen all the time, though for the last ~30 or so minutes and many messages seems to be happening consistent for me. I have 2 mail servers, basically clones, and thus master master replication. Most of the time things work fine. But many times an email or several will arrive on one, and never replicate to the other. I am not as concerned on the never replicating, as I am that the user never gets notified. Mail arrives on say server 1, users are checking mail on server 2, and they never see the email on server 2. This is not always the case, but its happening enough daily. I then log into one and run sync manually. Which usually syncs the mail on both servers, and then it arrives in the inbox. Here is an example, mail is on mail2, but not mail1. I am checking email on mail1 so I am not seeing the 1 email. Mail1 /home/wlt-ml/.maildir/new: total 0 Mail2 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673024.7643.mail2 Then I manually log into mail2 and run this command, though usually I can run it from either side, and just change the name to the other server. doveadm sync -u "*" remote:mail1 And then I end up with the missing email on mail1, and it arrives in my email client shortly there after Mail1 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673051.M838843P26735.mail1,S=8502,W=8678:2,T I have no idea why it does this. It seems to happen when when a full sync has taken place per doveadm replicator status wlt-ml. There does not seem to be any settings to force a full vs fast sync more often. No clue if this is even a full vs fast issue or other. I think it tends to happen more when people stay connected to the imap server. I had a theory that closing the email client and opening it again will get dovecot to sync. I believe this is still the case, but not able to confirm 100%. Also users are reporting closing Thunderbird. I can see them logging out and back in in the logs, but email does not replicate or show till I run doveadm sync manually. Tempted to have cron invoke that on the regular, but seems very hackish and likely will have its own issues doing that. Since its not the right way or how things were designed. Not sure if this is a bug or what. Hopefully miss-configuration on my end. Open to any feedback, advice, etc. I can provide replicator configuration but its pretty straight forward and mostly copy/paste from the replication page. Replication works, just seems it is not triggered to replicate at times or something. dovecot --version 2.2.22 (fe789d2) -- William L.

Allowing for multiple recipient_delimiter characters?
by Aaron Lindsay 23 Mar '16

23 Mar '16

Postfix allows the recipient_delimiter configuration parameter to contain multiple characters, splitting on the first such character it encounters. For example, if using 'recipient_delimiter=+-' both aaron+foo(a)example.com and aaron-bar(a)example.com would be delivered to aaron(a)example.com. Is anyone opposed to changing dovecot's handling of recipient_delimiter so that it's the same as that of postfix? If not, I am willing to rebase/merge/address review comments on Lennart Weller's patch[1] to get this functionality upstream. While I think aligning with postfix' behaviour would be convenient for those of us who run a server using both dovecot and postfix, would this break any other common use cases I'm not aware of? Thanks! -Aaron [1] - http://dovecot.org/pipermail/dovecot/2015-February/099660.html (I've talked with Lennart off-list, and he's OK with me working to get his patch merged, as long as I attribute his work to him, but doesn't have the time to work on it himself right now)

protocols.d/ dir empty?

22 Mar '16

(I hope I'm doing this right) Hey there. I have a problem with the dovecot protocols. When I do /telnet 127.0.0.1 143/ it gives me a connection refused error. I looked in the wiki and then after trying /doveconf protocols listen /I realized that I don't have any protocols.//I went in //usr/share/dovecot/protocols.d/ and it's empty. How can I fix that?

multiple imapc settings in different namespaces
by abi＠oleane.net 22 Mar '16

22 Mar '16

hello all i assume this question must have already been asked, but i'm looking for a way to circumvent which might work specifically on my system. the version can be any available version between 2.2.9 and 2.2.22 (i'm testing with both of the above and no other ) i'm using imapc in 2 different namespaces. in both cases, the imapc_host is local, and a custom passdb program is expected to handle proxying to different servers. one of the case should proxy to a different legacy platform, and the other is used for shared mailboxes. is there any way at all to be able to tell which is which in passdb ? i don't care about the password, i can use a login prefix or suffix, different ports, different master passwords, ssl, maybe a different protocol name or auth method... somehow i've seen in the source code there is a namespace "owner" but did not manage to change this parameter. i guess it is used internally. anything else ? thanks a lot for any help you can provide best regards @abi

sieve - editheader - edit in place
by Hajo Locke 22 Mar '16

22 Mar '16

Hello, i do some tests with sieve editheader extensions. deleteheader and addheader are working, but i noticed that new headerlines are always prepended to current header. So new lines can be found always on top. I am looking for a possibility to edit a headerline in place, without moving the new line to top of stack(replaceheader?). It is not looking good if a Subject-Line suddenly moves to top of header. Is there a possibility for me? Thanks, Hajo

doveadm sync/backup doesn't sync the metadata?
by Heiko Schlittermann 21 Mar '16

21 Mar '16

Hello, in a current migration project we want to migrate from Cyrus to Dovecot. The Cyrus server stores expiry information as ANNOTATIONS. On the Dovecot side I've set up the metadata/annotations plugin and it is working. But 'dovecot backup …' doesn't seem to sync these metadata? Did I miss something here? Shouldn't the metadata be part of the backup? (I'm using the latest 2.2.22 for sync purposes, as the stock dovecot just crashed when used as 'doveadm backup …') Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.

Understand the UID value in mailbox debug
by Tobi 21 Mar '16

21 Mar '16

Hi list we have a client who complains that mails from a certain sender are always put into his spamfolder. Our strong guess is that this is an issue with the webmail (Roundcube), but I need some help in understanding the output from dovecot's mailbox-debug. In order to narrow down the source of the problem we activated the mailbox-debug from Dovecot. Now we can see that the mail is moved into the spamfolder. But the strange thing is that a UID is logged which does not exist on the mailserver The following log is the "move" of the mail into the spamfolder Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW copy from INBOX: box=INBOX.Spam, uid=58, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW delete: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imapREMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW expunge: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 I do not understand whose UID this is, as it does not exist on the server. Does dovecot create temporary UID or something like that? Or is it more a process ID? Thanks and regards tobi

Re: Setting up public mailboxes - user not found
by Marti Markov 20 Mar '16

20 Mar '16

Hey, I actually went with the method suggested by Steffen Kaiser of creating a separate userdb because I use LDAP and I have an OU which contains all the public mailboxes and was just easier. I setup the userdb like so: userdb { args = /etc/dovecot/dovecot-ldap-shared_mailboxes.conf.ext driver = ldap override_fields = mail=maildir:/home/vmail/Public/.%n } Now when I send an email to office3(a)xxx.com I don’t get any errors and it delivers the message to the office3(a)xxx.com: root@mail:~# ls /home/vmail/Public/.office3/new/ 1458427035.M781836P21781.mail.xxx.com,S=2571,W=2630 1458427705.M750112P23338.mail.xxx.com,S=2501,W=2559 But from any mail client I try I don’t seem to be able to list anything in the Public directory. Am I missing something in the configuration?

http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz.sig + Added doveadm HTTP API: See http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP + virtual plugin: Mailbox filtering can now be done based on the mailbox metadata. See http://wiki2.dovecot.org/Plugins/Virtual + stats: Added doveadm stats reset to reset global stats. + stats: Added authentication statistics if auth_stats=yes. + dsync, imapc, pop3c & pop3-migration: Many optimizations, improvements and error handling fixes. + doveadm: Most commands now stop soon after SIGINT/SIGTERM. - auth: Auth caching was done too aggressively when %variables were used in default_fields, override_fields or LDAP pass/user_attrs. userdb result_* were also ignored when user was found from cache. - imap: Fixed various assert-crashes caused v2.2.20+. Some of them caught actual hangs or otherwise unwanted behavior towards IMAP clients. - Expunges were forgotten in some situations, for example when pipelining multiple IMAP MOVE commands. - quota: Per-namespaces quota were broken for dict and count backends in v2.2.20+ - fts-solr: Search queries were using OR instead of AND as the separator for multi-token search queries in v2.2.20+. - Single instance storage support wasn't really working in v2.2.16+ - dbox: POP3 message ordering wasn't working correctly. - virtual plugin: Fixed crashes related to backend mailbox deletions.

TLS handshake issue
by John Oliver 18 Mar '16

18 Mar '16

dovecot-2.0.9 on CentOS 6.7 The system in question is not connected to the Internet, so I can't copy-and-paste. I have to type anything required :-( Brand-new out-of-the-box install with a really minimal dovecot.conf including: service imap-login { inet_listener imaps { address = 192.168.1.10 port = 143 ssl = yes } } ssl_cert=</etc/pki/tls/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL ssl_key =</etc/pki/tls/private/dovecot.pem That's very, very similar to an existing dovecot server on an old VM I need to replace. Certs are self-signed, I know that's a horrible thing to do, but right now we don't have any choice. I'm connecting with Apple Mail 8.2 running on OS X 10.10.5, another thing we have no choice about :-/ The Apple Mail just sits there stupidly. It's "Connection Doctor" just helpfully reports that it can't establish a connection. I can use 'openssl s_client -showcerts -connect mail:143' and see what I expect to see. The dovecot log with lots of verbosity enabled tells me: imap-login: Info: Disconnected (no auth attempts): rip=192.168.1.200, lip=192.168.1.10, TLS handshaking: Disconnected auth: Debug: auth client connected (pid=21006) imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2002, ret=1: SSLv2/v3 read client hello A [192.168.1.200] And that's it... those lines get repeated every minute that Mail is running. I'm not seeing anything in any logs that even hints at what it's unhappy about, or any way to increase verbosity any more. Any hints appreciated! -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

Released Pigeonhole v0.4.13 for Dovecot v2.2.22.
by Stephan Bosch 18 Mar '16

18 Mar '16

Hello Dovecot users, Here is the final v0.4.13 release of Pigeonhole for Dovecot v2.2.22. Nothing changed since the RC. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.13.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Trouble getting vnd.dovecot.filter and filter visible/usable...
by Tolbert, Joshua P 17 Mar '16

17 Mar '16

Hello, I’m trying to make vnd.dovecot.filter available both globally and for users through sieve, but I haven’t had much luck getting things to work right. Sieve scripts won’t validate and vnd.dovecot.filter never shows up in the managesieve capability list. I’ve spent lots of time looking for where problems could be, but I’m out of ideas…So I’m asking you guys. In the protocol lmtp section, I’m defining mail_plugins = $mail_plugins sieve, however I’ve tried it without $mail_plugins too…No luck that way either. Any help/advice would be much appreciated. Thanks! Cheers, Josh

Looking for way to monitor dsync, confirm it is or isn't running
by Rich Wales 17 Mar '16

17 Mar '16

I am syncing two Dovecot sites using the dsync function. I would like to be able to run some sort of periodic health check to confirm that dsync is (or is not) running properly between the two sites, and alert me if dsync is failing or lagging excessively. Does anyone know of a tool to do this? (If possible, something I can set up to run periodically in Nagios?) Thanks for any suggestions. Rich Wales richw(a)richw.org

Xi has a new home
by Stephan Bosch 17 Mar '16

17 Mar '16

Hi, The automatic package builder Xi has moved to system within the Dovecot infrastructure. This also means that the repositories are available at a new host name: xi.dovecot.fi. The old host name still works and is a CNAME pointing to the new venue. I expect the old domain to be active for years to come. So, there is no need to update your /etc/apt/sources.list right away. Still, it is a good idea to do so. I've updated the wiki accordingly. Regards, Stephan.

Re: spamc during dovecot-smtp delivery?

[cc'ing the list for posterity] also sprach Tolbert, Joshua P <jtolbert(a)illinois.edu> [2016-03-16 21:46 +0100]: > I’ve been working on a Postfix/Dovecot/sieve mail server migration > (from Sendmail/Dovecot/procmail) and ran in to a similar problem > to one you talked about a while ago on the dovecot mailing lists. > Did you ever find a good solution for running spamc as the > destination user in sieve? If you did, mind sharing? Thanks! I've never had a problem again since upgrading to Debian jessie, but I also think that the problem's solution was installing a NSS cache, because the deadlocks seemed to take place between Spamassassin and libnss-pgsql2. Transport from Postfix to Dovecot is lmtp:unix:private/dovecot-lmtp (no idea how to do that with Sendmail or why you'd want to use Sendmail) and then Dovecot's sieve is configured to run a filter using /etc/dovecot/sieve.before.d: require [ "vnd.dovecot.filter"]; filter "spamc" [ "--no-safe-fallback" ]; which is enabled in conf.d/90-sieve.conf with sieve_before = /etc/dovecot/sieve.before.d sieve_global_extensions = +vnd.dovecot.filter sieve_plugins = sieve_extprograms and in conf.d/90-sieve-extprograms.conf sieve_filter_bin_dir = /etc/dovecot/sieve-filter and then I made a simple symlink from /etc/dovecot/sieve-filter → /usr/bin/spamc Spamassassin starts with --create-prefs --helper-home-dir --allow-tell and the final step is to integrate the mail user database (vmm in my case) with libnss to provide spamassassin with a way to identify home directories. I use libnss-pgsql2. The /etc/nss-pgsql.conf file I use is available here: http://bugs.debian.org/818465 A successful delivery then looks like this: postfix/smtpd[29778]: connect from mail1.smtp.mailserver4.de[62.216.179.241] postfix/smtpd[29778]: 6D2F74024E: client=mail1.smtp.mailserver4.de[62.216.179.241] postfix/cleanup[32593]: 6D2F74024E: message-id=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx> postfix/smtpd[29778]: disconnect from mail1.smtp.mailserver4.de[62.216.179.241] dovecot: lmtp(3570): Connect from local spamd[2140]: spamd: connection from localhost [::1]:57032 to port 783, fd 6 spamd[2140]: spamd: setuid to xxxxxxx%yyyyyyyyyy.zz succeeded spamd[2140]: spamd: processing message <xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx> for xxxxxxx%yyyyyyyy.zz:70032 spamd[2140]: spamd: clean message (-1.9/5.0) for xxxxxxx%yyyyyyyy.zz:70032 in 3.0 seconds, 10222 bytes. spamd[2140]: spamd: result: . -1 - BAYES_00,DKIM_SIGNED,DKIM_VALID,HEADER_FROM_DIFFERENT_DOMAINS,HTML_MESSAGE,RCVD_IN_DNSWL_NONE scantime=3.0,size=10222,user=xxxxxxx%yyyyyyyy.zz,uid=70032,required_score=5.0,rhost=localhost,raddr=::1,rport=57032,mid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>,bayes=0.000000,autolearn=ham autolearn_force=no dovecot: lmtp(3570, xxxxxxx(a)yyyyyyyy.zz) copy from (file): box=INBOX, uid=30613, msgid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>, size=10945 dovecot: lmtp(3570, xxxxxxx(a)yyyyyyyy.zz) QLZ6IoJ/6lbyDQAARsnb6w: sieve: msgid=<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@xxxxxxxxxxxxxxxxxxxxx>: stored mail into mailbox 'INBOX' postfix/lmtp[3569]: 6D2F74024E: to=<xxxxxxx(a)yyyyyyyy.zz>, orig_to=<aaaaaa(a)bbbbbbb.zz>, relay=ambassador.madduck.net[private/dovecot-lmtp], delay=5, delays=2/0.02/0.01/3, dsn=2.0.0, status=sent (250 2.0.0 <xxxxxxx(a)yyyyyyyy.zz> QLZ6IoJ/6lbyDQAARsnb6w Saved) dovecot: lmtp(3570): Disconnect from local: Successful quit Hope this helps… -- @martinkrafft | http://madduck.net/ | http://two.sentenc.es/ "the public is wonderfully tolerant. it forgives everything except genius." -- oscar wilde spamtraps: madduck.bogus(a)madduck.net

Hi all, I got a question if its possible to subscribe a mailbox from another user, who contains non mutf7 valid chars in his mailbox path.

Plugin "last-login" - Log SMTP-AUTH information
by Benjamin Hück 16 Mar '16

16 Mar '16

Hello all, we are using the Plugin "last-login" [1] to update user's last-login timestamp or the timestamp of the last incoming message in a MySQL backend. Would it be possible to expand the plugin to also log the timestamp of the last smtp-auth attempt/successful process? Currently in our settings, a smtp-auth request (port 587) is forwarded by postfix to a dovecot backend server for authentication. I couldn`t find out the developer of the plugin otherwise I had contact them immediatly.

New dovecot user needs installation help
by Jason Pruim 16 Mar '16

16 Mar '16

Hey Everyone, So I just setup my first dovecot install with postfix running for the mail server… I can telnet into my dovecot install and login just fine with my user locally… But when I try to add the account from my phone, computer, or telnetting from my local computer, it just hangs and eventually kicks back a generic error saying it can’t be added… Where can I start looking? I’m hosted with amazon web services and I’m waiting on them to approve my request to white list my IP on my instance, but that should only restrict my ability to send email out on port 25… I should still be able to operate locally… According to the firewall on amazon port 143 and 993 are both allowed from any IP address into the server (All outbound traffic is currently open until I get it working) I’m thinking it’s something easy, and I can handle pointers! I don’t necessarily need my hand held the entire way… At least not yet… Here is the output of my dovecot -n: [ec2-user@ip-172-31-22-222 log]$ dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 3.14.48-33.39.amzn1.x86_64 x86_64 mail_location = mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } [ec2-user@ip-172-31-22-222 log]$ Let me know if there is anything else you need, or where to go from here!

Reappearing emails - IMAP trace
by Ron Cleven 16 Mar '16

16 Mar '16

A few days back, I sent an overview of this problem, but received no responses. Since then, I have run dozens of traces to isolate the problem, difficult because there are timing issues involved. I have finally nailed it down. If this is not the proper place to report such bugs or if someone knows that this bug has been fixed, please let me know. As I noted in my earlier post, we have been running Dovecot 2.2.10 with a pair of CentOS 7 boxes with replications for the past year. We have been quite happy with the performance and reliability. Recently we received a report that emails could reappear in the INBOX after being deleted. After running a pile of traces, I determined that the problem was strangely related to replications. For the purposes of this discussion, I will refer to the two symmetric replicating servers as A and B. Further, let us assume that during "normal" operation, all the emails are delivered to A via SMTP and are replicated to B. Under those assumptions, if the IMAP user connects to A (where the messages were originally delivered), there is no problem, at least no problem I was able to find. The problem I am describing only arises if the IMAP user connects to B. Connecting to B has never presented any other problems that I am aware of. The test for which I have provided the trace starts with a test mailbox containing only 3 unread messages in the INBOX. Moving 1 of the unread messages to Trash is all that is needed to reproduce the problem. Remember this is ONLY a problem if the IMAP sessions do not connect to the server to which the messages were originally delivered. Also, I found that there is a timing window. The critical IMAP commands are: UID STORE xxx +FLAGS.SILENT (\Seen) UID MOVE xxx Trash If you introduce a large enough delay (I arbitrarily chose 5 seconds) between those two commands, there is no problem. Presumably this has to do with the two boxes syncing up some critical data structure. It takes a short time for the message that was moved to Trash to reappear in the INBOX. The trace initially shows the number of messages going from 3 to 2 when the message is moved to Trash, but a second or so later, the message count goes back up to 3. Interestingly, the reappearing message shows back up as Unseen in the INBOX but a duplicate copy of it stays in Trash as Seen. Dragging unread messages to Trash may not be polite, but it is technically acceptable. Regarding the trace below , CR's show up as \r, LF's show up as \n, and each line starts with S or C depending upon whether it is from the Server or Client.

syncing mailboxes with dsync after switchover
by Sergey Schwartz 16 Mar '16

16 Mar '16

Gents, I'm relocating mailboxes to a new server. Before switching over to a new server I ran syncing a few times without any issues first I sync files with rsync from the old server to have a local copy, then I sync mailboxes with dsync /usr/bin/doveadm -Dv sync -u $MBOX -R "sdbox:/srv/vmail/temp/srv/srv.bgoperator.ru/${MBOX}:DIRNAME=DbOx-mAiLs" After switching over smtp transport and running dsync as above a few mailboxes were deleted dsync(xxx): Warning: Deleting mailbox 'INBOX': UID=1 already exists locally for a different mail: GUIDs don't match (c005a206e1c6e756f02700003a8929e2 vs 0ba1c03796f5dc524c6d0000b4ca29ec) dsync(xxxx): Warning: Deleting mailbox 'INBOX': UID=8855 GUID=80d5841f0fe2e35677630000b4ca29ec is missing locally dsync(xxxxx): Warning: Deleting mailbox 'INBOX': UID=7508 already exists locally for a different mail: GUIDs don't match (1e03d72074d8e756403700003a8929e2 vs 1dc47a3ac5c4e7562a290000b4ca29ec) dsync(xxxxxx): Warning: Deleting mailbox 'INBOX': UID=8238 GUID=2a6a803bd33fe156f85e0000b4ca29ec is missing locally and a few other mailboxes seemed to fail to sync dsync(xxxxxxx): Warning: Mailbox changes caused a desync.

VS: New dovecot user needs installation help
by Aki Tuomi 15 Mar '16

15 Mar '16

Can yoi run doveadm log errors too? ---Aki TuomiDovecot oy -------- Alkuperäinen viesti --------Lähettäjä: Jason Pruim <pruimj(a)gmail.com> Päivämäärä: 15.3.2016 4.50 (GMT+02:00) Saaja: dovecot(a)dovecot.org Aihe: New dovecot user needs installation help Hey Everyone, So I just setup my first dovecot install with postfix running for the mail server… I can telnet into my dovecot install and login just fine with my user locally… But when I try to add the account from my phone, computer, or telnetting from my local computer, it just hangs and eventually kicks back a generic error saying it can’t be added… Where can I start looking? I’m hosted with amazon web services and I’m waiting on them to approve my request to white list my IP on my instance, but that should only restrict my ability to send email out on port 25… I should still be able to operate locally… According to the firewall on amazon port 143 and 993 are both allowed from any IP address into the server (All outbound traffic is currently open until I get it working) I’m thinking it’s something easy, and I can handle pointers! I don’t necessarily need my hand held the entire way… At least not yet… Here is the output of my dovecot -n: [ec2-user@ip-172-31-22-222 log]$ dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 3.14.48-33.39.amzn1.x86_64 x86_64 mail_location = mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } [ec2-user@ip-172-31-22-222 log]$ Let me know if there is anything else you need, or where to go from here!

dovecot wiki...
by Andrew McGlashan 15 Mar '16

15 Mar '16

Hi, Just want to know if this is a problem at my end (in my browser), or if it is something else. When I copy text from the wiki, the page changes to an edit one; that is very, very annoying. How can I stop this if it is normal dovecot wiki behaviour and what do you think I might look at in my browser if it isn't? I'm never likely to want to edit the wiki any time soon. Thanks AndrewM

Logging the TLS cipher suite

Hi, could it be possible to log the TLS cipher suite as Postfix does? This is a typical TLS Dovecot log line: imap-login: Login: user=<user(a)acme.com>, method=DIGEST-MD5, rip=1.2.3.4, lip=4.3.2.1, mpid=19671, TLS, session=<Jsvr46wt2c1ScQfY> This is the Postfix equivalent postfix/smtp[59723]: Anonymous TLS connection established to mail.acmne.com[1.2.3.4]:25: TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits) -- Ciao, luigi / +--[Luigi Rosa]-- \ We're not surrounded, we're in a target-rich environment!

Timout for LDAP connection
by Gordon Grubert 11 Mar '16

11 Mar '16

Hi, we are using a round robin dns record for connections to our ldap system. This works fine for almost all cases. In particular, for dovecot does this mean, when an ldap server is stopped, dovecot instantly reconnects to another ldap server. But when the network connection to the active ldap server is broken, dovecot sticks to the failed ldap server. Is there any possibility to define a connection timeout? This is our current configuration for the ldap connection: # 2.2.devel (2d8f665): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (0de2a19) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.3 uris = ldaps://LDAP-SERVER dn = BINDDN dnpass = BINDPASS auth_bind = yes ldap_version = 3 base = BASEDN scope = subtree user_attrs= ATTRIBUTES user_filter = USERFILTER pass_filter = PASSFILTER iterate_filter = ITERATEFILTER Best regards, Gordon -- Technischer Leiter & stellv.

Troubleshooting mailbox problems
by Nick Bright 11 Mar '16

11 Mar '16

Greetings, I'm running Dovecot 2.0.9 on my CentOS 6 server, for several thousand mailboxes. Recently, I've had several reports of "my mailbox is suddenly empty, where'd my mail go?" I've enabled debug logging, but I'd like to make sure I have the best level of debug to see things like "delete message" commands? I've configured in logging: auth_debug = yes auth_debug_passwords = no mail_debug = yes plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_group_events = yes mail_log_fields = uid box msgid size } Does this look like a good start? I really think it's a client side problem, but sometimes end users always want to blame the server; and proof must be shown e.g. "Look, here's the log, you're sending delete commands." At which point, we can proceed with dealing with their software problem.

Setting up public mailboxes - user not found
by Marti Markov 10 Mar '16

10 Mar '16

Hi all, This is the first time I use the dovecot mail list so I’m sorry if I forget something. My problem is that for some reason I can get public mailboxes to work. I have setup the directory Public, the folders and the cur,tmp and new folder in them: Public | |- .office3 | |- cur |- tmp |- new |- dovecot-acl Here is my dovecot conf: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14.32-xxxx-grs-ipv6-64 x86_64 auth_default_realm = xxx.com auth_mechanisms = plain login mail_gid = vmail mail_home = /home/vmail/%d/%n mail_location = maildir:~/Maildir mail_plugins = acl mail_uid = vmail 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 namespace { list = yes location = maildir:/home/vmail/xxx.com/Public:INDEXPVT=~/Maildir/Public prefix = Public/ separator = / subscriptions = yes type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile sieve = ~/.dovecot.sieve sieve_before = /etc/dovecot/sieve/dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)xxx.com protocols = " imap lmtp sieve" service auth { unix_listener auth-client { group = Debian-exim mode = 0660 user = Debian-exim } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener lmtp { mode = 0666 } } ssl = required ssl_cert = </etc/dovecot/xxx.com.pem ssl_key = </etc/dovecot/private/xxx.private.pem ssl_key_password = yyyyyyy userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_plugins = acl sieve } protocol imap { mail_plugins = acl imap_acl } The error I’m getting is that LMTP can’t deliver to office3(a)xxx.com because the user could not be found.

I’m not sure but should Dovecot skip this and check the Public folder first before checking LDAP? Another part of my setup is Exim4. Here is the transport part: dovecot_lmtp: driver = lmtp socket = /var/run/dovecot/lmtp return_path_add #maximum number of deliveries per batch, default 1 batch_max = 200 And here is the auth part: dovecot_login: driver = dovecot public_name = LOGIN server_socket = /var/run/dovecot/auth-client # setting server_set_id might break several headers in mails sent by authenticated smtp. So be careful. server_set_id = $auth1 .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}} .endif dovecot_plain: driver = dovecot public_name = PLAIN server_socket = /var/run/dovecot/auth-client server_set_id = $auth1 .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}} .endif So any tips on how to fix this would be great.

zlib plugin doesn't add "Z" flag to Maildir filename
by Tom Sommer 10 Mar '16

10 Mar '16

I enabled zlib compression, so new mails are saved compressed. Now I want to convert the old mails to gzip with the find and gzip command, but now I don't know which files are already gzip compressed by dovecot. Shouldn't zlib_save itself add Z to the Maildir flags? As suggested in the compress guide on http://wiki2.dovecot.org/Plugins/Zlib ? -- Tom

v2.2.22 release candidate released
by Timo Sirainen 10 Mar '16

10 Mar '16

http://dovecot.org/releases/2.2/rc/dovecot-2.2.22.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.22.rc1.tar.gz.sig There are some larger changes here, especially to doveadm to make it support HTTP API. There's still time to do smaller tweaks to the API, so let us know if you have some improvement ideas. Note that the API was designed to look mostly like JMAP, which we're planning to implement also for v2.3. The plan is to fork v2.3 development tree soon. + Added doveadm HTTP API: See http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP + virtual plugin: Mailbox filtering can now be done based on the mailbox metadata. See http://wiki2.dovecot.org/Plugins/Virtual + stats: Added doveadm stats reset to reset global stats. + stats: Added authentication statistics if auth_stats=yes. + dsync, imapc, pop3c & pop3-migration: Many optimizations, improvements and error handling fixes. + doveadm: Most commands now stop soon after SIGINT/SIGTERM. - auth: Auth caching was done too aggressively when %variables were used in default_fields, override_fields or LDAP pass/user_attrs. userdb result_* were also ignored when user was found from cache. - imap: Fixed various assert-crashes caused v2.2.20+. Some of them caught actual hangs or otherwise unwanted behavior towards IMAP clients. - Expunges were forgotten in some situations, for example when pipelining multiple IMAP MOVE commands. - quota: Per-namespaces quota were broken for dict and count backends in v2.2.20+ - fts-solr: Search queries were using OR instead of AND as the separator for multi-token search queries in v2.2.20+.

Using dsync to synchronize laptop against remote server
by Dato Simó 10 Mar '16

10 Mar '16

Hello! I’m thinking of changing the way I sync mail to my laptop, and I have a couple questions about my intended setup. In brief, my plan is: instead of running offlineimap against various IMAP accounts (my personal one included), I will run fetchmail on my private server, and classify mail with Sieve there. Then I’ll run a local Dovecot on my laptop, and do a master/master replication from my personal server/account with dsync. I have two quick questions about this (I have never used dsync before): 1. Reading the manual page, it seems that I probably want stateful synchronization (-s flag). Not having used it before, I’m curious about what lag I can expect. Does it compare to an IMAP IDLE/IMAP NOTIFY connection? Or is it asynchronous / with a timer? 2. I assume modifying my local Maildirs with e.g. Mutt is... a big no-no? Instead, should I always force Mutt to go through the local IMAP server? Many thanks in advance, -d

Re: Dovecot stops responding when I update SSL certificate
by HotSlots Webmaster 10 Mar '16

10 Mar '16

Time to put an end to this saga... I had an issue that Dovecot refused to serve an updated SSL certificate - one that Postfix had no issue with. Though I quadruple-checked that the cert file and private key file were correct, in the end I simply directed both cert and key files to the file I was using for Postfix (which had both the cert and private key). That worked. Darned if I know what it didn't like about the other files, but I'm back in business with the new cert. Thanks for the responsiveness from Aki. Steve L

Replication not working
by Simon Pierre Desrosiers 10 Mar '16

10 Mar '16

Hello, I am trying to setup replication between two Mac OS X El Capitan Server. I have added the field as I could understand from the replication page of dovecot and from a few poste in the mailing list. The mac uses the system user _dovecot as main system account. I have setup ssh keys between the two systems for the two _dovecot servers. SSh works fine from the terminal. But yet, I get these messages in the log file : Mar 09 20:18:44 auth: Error: od[getpwnam_ext](submit): No record for user Mar 09 20:18:44 doveadm: Error: Host key verification failed. Mar 09 20:18:44 dsync-local(submit): Error: read(_dovecot(a)laposte.mycompagny.com) failed: EOF Mar 09 20:18:44 dsync-local(submit): Error: Remote command returned error 255 Mar 09 20:23:44 auth: Error: od[getpwnam_ext](submit): No record for user Mar 09 20:23:44 doveadm: Error: Host key verification failed.

I have a few things about which I am not sure. We configure port 12345, but nothing listen on that port. The doveadm_password, what is it exactly ? Should I use a distinct account than _dovecot for synchronisation (all the fields that need to be added for replication) ? Here is my configuration, any help would be appreciated : # 2.2.5: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 15.3.0 x86_64 hfs auth_mechanisms = cram-md5 digest-md5 gssapi

Released Pigeonhole v0.4.13.rc1 for Dovecot v2.2.22.rc1.
by Stephan Bosch 10 Mar '16

10 Mar '16

Hello Dovecot users, Pigeonhole v0.4.12 still compiles against Dovecot v2.2.22.rc1, but only with warnings. That is the primary reason for this new release. However, there are also a few significant changes as listed below. When no significant problems are reported, a definitive release will follow closely after Dovecot v2.2.22 is released. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

segfault in imap and doveadm
by Joe Beaubien 07 Mar '16

07 Mar '16

Hi everyone, Dovecot keeps on segfaulting on me and I am unsure why. This setup has been running for 5 years and has given me very little trouble. I am running Dovecot 2.1.7, setup with mdbox. The imap process keeps on segfaulting for the same account (makes me think maybe an email or folder of that account is problematic). My big issue is that force-resync also causes doveadm to segfault. Here is the mail.err file I am getting: Mar 7 12:34:36 mba kernel: [ 1955.486324] imap[5663]: segfault at 0 ip 00007ff1c1bd0b5e sp 00007fffd8599a40 error 4 in libdovecot-storage.so.0.0.0[7ff1c1b51000+fb000] Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Sara/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:37 mba dovecot: imap(document): Error: mdbox map /mba_data/emails/document/storage/dovecot.map.index corrupted: map_uid=284393 refcount too low Mar 7 12:34:37 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Templates/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:39 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Sent/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:42 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/_EE - a verifier/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:43 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:48 mba kernel: [ 1967.972883] imap[5688]: segfault at 0 ip 00007f058ebc9b5e sp 00007fff9baa7c00 error 4 in libdovecot-storage.so.0.0.0[7f058eb4a000+fb000] Mar 7 12:34:49 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:43:44 mba dovecot: imap(document): Error: indexer disconnected unexpectedly Mar 7 12:43:44 mba dovecot: indexer: Error: Indexer worker disconnected, discarding 119 requests for document Mar 7 12:48:31 mba kernel: [ 2790.363755] doveadm[6586]: segfault at 0 ip 00007f1b2023fb5e sp 00007fff4e8ce200 error 4 in libdovecot-storage.so.0.0.0[7f1b201c0000+fb000] Mar 7 12:49:10 mba kernel: [ 2829.203900] doveadm[6604]: segfault at 0 ip 00007fa0d16e4b5e sp 00007fff1b89f480 error 4 in libdovecot-storage.so.0.0.0[7fa0d1665000+fb000] First line is imap segfaulting.

questions regarding zlib plugin
by Götz Reinicke - IT Koordinator 07 Mar '16

Hi, faced with a current space problem on our dovecot 2.2.18 server, I thought about using the zlib plugin. My questions: - is it really as simple as adding the options to the conf files as described in the docs :) ? http://wiki2.dovecot.org/Plugins/Zlib - As this just compresses new messages; dose anybody has a sort of simple cron or whatever script or best practice how to compress existing maildir mails? The doc is a bit complicated to me at that point... Thanks a lot and regards . Götz

It's possible it's generating ephemeral DH keys. In a previous post to this list, I note that the run time to generate these keys can vary wildly, and gets worse with longer keys. Sometimes you get lucky, and you'll generate then quickly, sometimes it takes a long while (minutes). http://dovecot.org/pipermail/dovecot/2015-November/102447.html Try running openssl dhparam -noout 2048 to see how it varies for you. If what I suspect is true, you can try using shorter keys. A followup post suggest a way you can precompute the key Joseph Tam <jtam.home(a)gmail.com>

Thank you for your suggestion! As much as I hate Outlook (Look Out!), there are loads of people using really old versions; 2003 is no longer supported, but loads of people use 2007. Thunderbird can be expected to be far more up to date. Implementing features to work with older clients will always be a problem. Just a simple example, almost unrelated here, but this is either wrong by TB or wrong by Outlook (versions 2007, 2010 and 2013 that I know of). When the IMAP server sends a message, OL will pop up a window that requires the user to acknowledge the message via a popup. TB just pops up the message in the normal 'new mail' notify if that is configured and it might be lost if notify isn't set to show. Either way, the implementation is different b/w the two client products. Is OL right or is TB right... IMAP doco says that the message should be made to be acknowledged by the client; OL's version can't easily be ignored or missed, but TB's can easily be missed. But TB's implementation is more user friendly if the server wants to keep sending messages from time to time. I considered using this for MOTD type stuff and maybe random inspirational or motivational messages; even to remind or inform users to do certain things [one example in the dovecot wiki is to advise that the vacation message is still active]. A TB notification is next to harmless, but an OL one needs to be acknowledged every time, which would be very painful. Anyway, the point is that if a feature is added for OCSP stabling support, you couldn't really expect older versions of Look Out to comply with it (even though M$ could patch it easily, they care less about older versions than getting people to subscribe to Office 365 these days).

Implementation of TLS OCSP Stapling
by dovecot＠flut.demon.nl 06 Mar '16

06 Mar '16

Hi all, About a year ago, Torsten already asked for OCSP stapling (http://dovecot.org/pipermail/dovecot/2015-April/100632.html) Unfortunately, there was no answer to his question. Now RFC 7633 ("TLS Feature Extension", https://tools.ietf.org/html/rfc7633, a.k.a. "Must Staple") has landed, revocation is getting serious! I personally would like to embed all my TLS certificates with the must-staple extension. The great project Let's Encrypt already supports it: https://github.com/letsencrypt/boulder/pull/1224 I'm aware most MTAs don't really care about the certificate, but big players as Google take TLS encryption very seriously: https://googleblog.blogspot.nl/2016/02/building-safer-web-for-everyone.html So I would like to know if Dovecot is planning to feature OCSP stapling. That way I know for sure my "must staple" certificates can be used by Dovecot. And in my opinion, every TLS offering daemon should be up to par to the capabilities of TLS.. Not lag behind :) What's your opinion on this matter? Thanks in advance for any anwser! Greets, Osiris

dovecot local indexes and multiple servers
by alex 05 Mar '16

05 Mar '16

Hi, I've been testing mdbox with local indexes on our nfs based directors + multiple imap/lda/pop3 server setup. The performance is noticeably better than maildir with indexes on nfs, so I'd like to make this work. About the possible direction to other servers the wiki says that it will create a new index 'on the fly'. That is true, but after the index is recreated, Thunderbird (imap) re-downloads all the messages and sees all those messages as unread again! This is probably quite logical as the message status is only kept in the indexes, but this is not very customer friendly. Is there a way to avoid this problem? I'd rather not manually sync those local indexes between our servers. In fact, I was planning on deleting (old) indexes when a user moved to another server or even if they haven't checked their mail for XX days. with up to 10Gb mailboxes the indexes themselves can get up to 20-40Mb for a mailbox. that amounts to quite a lot of storage for 200k+ users. Thanks, Alex.

It's time to renew the SSL certificate, so I did (same CA). The new certificate works fine in Apache and Postfix. But when I update Dovecot to use the same certificate, and restart the server, Dovecot stops responding to connects. I have triple-checked that the ssl_cert and ssl_key files are correct - all I did was change the names in the conf file. There's nothing in the log. I have tried various SSL tests but either they don't work (unspecific error) or they tell me nothing is wrong (and show the correct certificate.)

Dovecot stops responding when I update SSL certificate
by HotSlots Webmaster 05 Mar '16

05 Mar '16

Dovecot 2.2.18 CentOS 6.7 (x86_64) Plesk 12.5.30 I have had Dovecot working fine with SSL for nearly two years now. It's time to renew the SSL certificate, so I did (same CA). The new certificate works fine in Apache and Postfix. But when I update Dovecot to use the same certificate, and restart the server, Dovecot stops responding to connects. I have triple-checked that the ssl_cert and ssl_key files are correct - all I did was change the names in the conf file. There's nothing in the log. I have tried various SSL tests but either they don't work (unspecific error) or they tell me nothing is wrong (and show the correct certificate.) I am running out of time to find a solution to this - what else can I look for? The one difference for the certificates is that I opted for one with a SHA256 root rather than SHA1 root. I have separately used a tool to verify that the certificate and private key match.

Dear All, I'd like dovecot-lda (deliver) to post a message to a public mailbox. It doesn't seem to work when I just use the -m parameter with the IMAP-Mailbox path, e.g. Public/info . What parameters are required? Do I have to change the headers with formail in any way? TIA! - Chris

Found bug in quota-status + patch
by Thierry Coppey 03 Mar '16

03 Mar '16

Hello, I've found a bug in the quota-status util (Dovecot 2.2.21, and probably below): it always return OK (sufficient quota) because it fails to load the user properly. More specifically, the branch " if (quser == NULL) return 1; " in src/plugins/quota/quota-status.c:59 is always taken. (at least with postgresql backend, test your config with the (adapted) command below: printf "recipient=mailbox(a)example.com\nsize=10000000000\n\n" | nc inet:mailstore.example.com 12340 it should reject, unless you have no quota, or more than 10G). Therefore it is pointless to configure the quota-status service as described in http://wiki2.dovecot.org/Quota because of that bug: the mail would be always accepted from the client and rejected at the end of the (Postfix) processing by lda. It is possible to reject directly at SMTP level when the mailbox is full using Postfix and main.cf: smtpd_recipient_restrictions = ... reject_unauth_destination, ... check_policy_service inet:mailstore.example.com:12340 smtpd_end_of_data_restrictions = check_policy_service inet:mailstore.example.com:12340 However there remain a *small inconsistency* as lda will count the size of message including headers whereas smtpd_end_of_data_restrictions seems not to count them towards the message size (or additional headers might be added by other preprocessing e.g. antispam etc...) I propose the patch below to fix quota-status. Could an expert double-check that it doesn't have memory leaks? (it shouldn't but I'm not yet comfortable enough with Dovecot memory management). Best regards, Thierry C.

Dual certificate
by Jean-Baptiste Vignaud 03 Mar '16

03 Mar '16

Hello all; Is anyone knows if it's possible to have a dual certificate setup on dovecot like in postfix or apache ? i tried to add several crts in local name section : local_name imap.server.tdl { ssl_cert = <server_rsa_crt.pem ssl_key = <server_rsa_key.pem ssl_cert = <server_ecdsa_crt.pem ssl_key = <server_ecdsa_key.pem } but it seems that dovecot takes the last one (ecdsa) and that rsa cert is not used. to check if booth are working, i check with openssl: openssl s_client openssl s_client -connect imap.server.tdl:143 -starttls imap -servername imap.server.tdl -cipher ECDHE-RSA-AES128-GCM-SHA256 for rsa and openssl s_client openssl s_client -connect imap.server.tdl:143 -starttls imap -servername imap.server.tdl -cipher ECDHE-ECDSA-AES128-GCM-SHA256 for ecdsa In apache we have to duplicate the cert / key lines one for rsa, one for edcda. In postfix, we have some specific ecdsa conf keys. So is there a way to do the same in dovecot ?

user configuration question
by Eric Abrahamsen 02 Mar '16

02 Mar '16

I've been using mbsync to sync this email account to a local Dovecot installation. I used to use Gmail, through Google Apps, and a while ago switched the account to self-hosting. I didn't want to upload years' worth of old email to my old server, so I've had two accounts in my MUA: one talking to the local Dovecot account for the old emails, and a second talking directly to the server for the new emails. I'd like to sync the new account to Dovecot as well, and I'm having trouble wrapping my brain around how to configure the two side-by-side accounts in Dovecot (I know there are other solutions to this, but I'm also just trying to figure out how this works). What I don't grok is the exact effect of the different username fields in the passdb file, and how they combine with username_format. Right now my dovecot.conf has this: passdb { driver = passwd-file args = username_format=%u /etc/dovecot/passwd } userdb { driver = static args = uid=eric gid=users home=/home/eric/.mail/%d/%n username_format=%u default_fields = mail=maildir:/home/eric/.mail/%d/%n/mail } And /etc/dovecot/passwd: eric@ericabrahamsen.net:{PLAIN}password:eric@ericabrahamsen.net Say I want to keep my existing mail where it is, and have all the new mail go into ~/.mail/ericabrahamsen.net/eric-new/mail. Ie, when mbsync connects to the local Dovecot, it does so with the username eric-new(a)ericabrahamsen.net. Now, in Dovecot's conf, do I change the email address in the first field of /etc/dovecot/passwd, or the third field, or both? And, if it isn't too much trouble, what is the difference between the two? Thanks! Eric

Dsync induces redundant mail after rapid append/expunge repeatedly
by 潘信傑 02 Mar '16

02 Mar '16

I meet the problem about dsync with expunge. The problems is expunged mail would reappear after dsyncing and it is easily to reproduce. Environment Settings: - Two servers(serverA, serverB) both enabled plugin "*replication"* - And more detail get by "dovecot -n" show below Reproduce flow: - Run two processes pA and pB both would run in while loop - pA(All behavior is on Draft mailbox and all on serverA): - Clean "Draft" mailbox of userA - Run the following imap command of userA - imap save (save new mail to Draft) - imap delete (delete old mail on Draft) - imap expunge * - Check if draft only have one email (it would be failed in about 50 loops)* - pB(Send mail to serverB): - Send new mail to userA (which would be save in INBOX) It would be easier reproduce by increasing server loading. I have found something - T he expunge changes from server A in dsync connection don't send immediately, these expunge changes appear after 1~2 dsync connection over. - The replicated mail is generated from serverB and sync back to serverA so expunged mail reappeared. dovecot -n (ServerA) #

Setup changes 1.x to 2.x -- custom POP3 account handling required.
by Andrew McGlashan 02 Mar '16

02 Mar '16

Hi, Previously I did /special/ processing for some email accounts; if a particular file existed in the user's home directory, then I caused the account to use /var/mail/$USER file for POP -- otherwise it used IMAP. Now, because I adjusted the setup for POP only, IMAP still worked perfectly well. Some users have both POP and IMAP access for various reasons. The special POP processing was done using a shell script [1] in place of: /usr/lib/dovecot/pop3 - which in turn called the normal binary once setting up the environment. Now, I have been forced to upgrade my Debian from squeeze-lts to wheezy and the dovecot setup is quite different. How can I implement my /wrapper/ script for POP handling now? Here is my current setup with dovecot -n ... # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 7.9 mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" service imap-login { inet_listener imap { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } } ssl = required ssl_cert = </etc/exim4/exim.crt ssl_key = </etc/exim4/exim.key userdb { driver = passwd } [1] This is the content of the original wrapper script: #!/bin/sh if [ -f $HOME/.use-mbox-for-pop3s ]; then export MAIL=mbox:$HOME/mail:INBOX=/var/mail/$USER export USER_INBOX=/var/mail/$USER if [ -f $USER_INBOX ] then export USER_INBOX_GROUP=$(stat -c %G $USER_INBOX) if [ $USER_INBOX_GROUP != $USER ] then ( date ls -l $USER_INBOX chown Debian-exim:$USER $USER_INBOX ls -l $USER_INBOX ) >> /var/log/usr-lib-dovecot--pop3-affinity.log fi fi else if [ -d $HOME/Maildir ]; then export MAIL=Maildir:$HOME/Maildir else export MAIL=mbox:$HOME/mail:INBOX=/var/mail/$USER fi fi # Finally execute the imap/pop3.

dsync issues due to Prefix difference?
by Mark Little 02 Mar '16

02 Mar '16

Hi everyone, I'm hoping I am just missing something obvious - but I cannot seem to get a one-way migration dsync working between two Dovecot servers because the Prefix configuration is different. I am doing a migration from our old Dovecot servers to some new cPanel based ones. Source: 2.2.15 Dest: 2.2.21 Here is the debug output for the sync: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_sieve_plugin.so doveadm(testuser(a)example.ca): Debug: Effective uid=1322, gid=1322, home=/khstor3/khmail-mailboxes/l/li/example.ca/testuser doveadm(testuser(a)example.ca): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir doveadm(testuser(a)example.ca): Debug: maildir++: root=/khstor3/khmail-mailboxes/l/li/example.ca/testuser/Maildir, index=, indexpvt=, control=, inbox=/khstor3/khmail-mailboxes/l/li/example.ca/testuser/Maildir, alt= doveadm(testuser(a)example.ca): Debug: Namespace : Using permissions from /khstor3/khmail-mailboxes/l/li/example.ca/testuser/Maildir: mode=0777 gid=default stdin: is not a tty dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: INBOX guid=f055ac07d79cad508a7a000075e38adc uid_validity=1353555159 uid_next=2085 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Junk guid=703a8b1d51ceab56f91e0000667eee40 uid_validity=1391566942 uid_next=1 subs=yes last_change=0 last_subs=1454100049 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Trash guid=9bee9f0f2aacb65039260000b171e44d uid_validity=1353555163 uid_next=25 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Drafts guid=4d03661058a0f1524f240000e9d81ad0 uid_validity=1391566936 uid_next=1 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Local mailbox tree: Sent guid=99ee9f0f2aacb65039260000b171e44d uid_validity=1353555161 uid_next=4 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Remote mailbox tree: INBOX guid=6460141741cfab5643470000afb0d608 uid_validity=1454100291 uid_next=2064 subs=no last_change=0 last_subs=0 dsync-local(testuser(a)example.ca): Debug: brain M: Remote mailbox tree: INBOX.Trash guid=6360141741cfab5643470000afb0d608 uid_validity=1454100290 uid_next=12 subs=yes last_change=0 last_subs=1454100289 dsync-local(testuser(a)example.ca): Debug: brain M: Remote mailbox tree: INBOX.Sent guid=6260141741cfab5643470000afb0d608 uid_validity=1454100289 uid_next=2 subs=yes last_change=0 last_subs=1454100289 dsync-remote(testuser(a)example.ca): Error: Couldn't find namespace for mailbox Junk I believe the problem is because on the source we have no prefix set, but on the destination it has INBOX as the prefix.

Alternative storage backend for Dovecot
by Oleksandr Natalenko 01 Mar '16

01 Mar '16

Hi. We have corporate Dovecot setup with GlusterFS as file storage. We store maildirs on GlueterFS share, mounting it via NFS. Mounting share via native GlusterFS FUSE client introduces visible performance overhead. Also, NFS mount does not provide us with HA. That's why I have an idea to use GlusterFS C API to access maildirs share. I'd like to preserve maildir structure, but get access to it not via FS mount point but with GlusterFS C API calls. I've discovered that Dovecot source tree has src/lib-fs infrastructure with fs-posix implemented on top of it. Is that the right place to start from? GlusterFS C API calls are POSIX-like, so they could be easily used as substitutions for VFS ops. Could such a backend be implemented as separate plugin? Are there any examples of alternative storage backend to look at? Thanks. Regards, Oleksandr.

Inconsistent mdbox index while running doveadm altmove
by Ricardo Machini Barbosa 01 Mar '16

01 Mar '16

Hello, I was performing doveadm altmove for one account while this mailbox was being accessed. Dovecot version: 2.2.21 Mailbox format: mdbox Command: doveadm altmove -u user1(a)domain.com.br before 360d This command took about 5 minutes to finish and during the execution I found some log messages: Feb 25 19:57:51 dovecot: imap(user1(a)domain.com.br): Error: mdbox map /var/mail/user1/mdbox/storage/dovecot.map.index corrupted: Unexpectedly lost INBOX uid=77 map_uid=76 Feb 25 19:57:51 dovecot: imap(user1(a)domain.com.br): Internal error occurred. Refer to server log for more information.

I had to execute doveadm force-resync -u user1(a)domain.com.br INBOX to recovery this mailbox, but losing all e-mail's flags. I should do some kind of lock before running the command altmove ? Regards, Ricardo

severe fork() problems with new dovecot server
by J. Niklas 01 Mar '16

01 Mar '16

Hi all, I am getting to you because I am pretty desperate by now. Please read this and share your ideas. I set up a new Mail server with roughly 750 active accounts on it, based on the usual dovecot+postfix+amavis+sql based vmail setup. This is not the first time I did something like this, but admittedly my largest setup so far. I took my time to setup everything pretty straight and stable and migrated all accounts in time with almost no glitches using imapc and pop3c. Things started out smoothly - until the first business morning when the log suddenly began to pop messages like these: dovecot: master: Error: service(imap): fork() failed: Resource temporarily unavailable dovecot: master: Error: service(pop3): fork() failed: Resource temporarily unavailable The error is not confined to a certain service. There are no other messages in dmesg or syslog which could help in closing in on the root cause. The server always runs at load around 0.4 to 0.5 and has plenty of RAM and Disk, too. Of course I checked resource limits and cranked up everything I could possibly think of to numbers that should easily suffice: /etc/security/limits.conf: daemon soft nproc 2048 daemon hard nproc 3128 dovecot soft nproc 2048 dovecot hard nproc 3128 vmail soft nproc 2048 vmail hard nproc 3128 vmail soft nofile 32768 vmail hard nofile 49152 /etc/systemd/system/dovecot.service.d/ulimits.conf: [Service] LimitNOFILE=65534 However, all my attempts on resolving the problem were futile so far. To work around the problem I implemented a log watcher which constantly looks for the fork failure and dumps some debug info before restarting dovecot to make the problem "go away" - until dovecot hits whatever barrier there is again. Here are today's numbers I gathered from this: > forkdump_03-01_09-42: pop=3, imap=446, all=503, postfix:22, sys: 716 > forkdump_03-01_10-09: pop=9, imap=444, all=510, postfix:28, sys: 741 > forkdump_03-01_10-42: pop=5, imap=450, all=507, postfix:25, sys: 748 > forkdump_03-01_11-18: pop=5, imap=451, all=512, postfix:29, sys: 757 > forkdump_03-01_11-48: pop=3, imap=474, all=511, postfix:37, sys: 765 > forkdump_03-01_12-23: pop=7, imap=444, all=511, postfix:22, sys: 752 > forkdump_03-01_12-53: pop=3, imap=444, all=503, postfix:24, sys: 747 > forkdump_03-01_13-21: pop=3, imap=458, all=504, postfix:31, sys: 766 > forkdump_03-01_13-41: pop=4, imap=451, all=505, postfix:23, sys: 755 > forkdump_03-01_14-35: pop=5, imap=436, all=502, postfix:31, sys: 768 > forkdump_03-01_14-59: pop=3, imap=445, all=501, postfix:27, sys: 764 > forkdump_03-01_15-28: pop=6, imap=452, all=507, postfix:25, sys: 769 There you see the number of pop3 and imap childs in the process list as well as the total number of all dovecot processes and all postfix processes, summarized directly after the fork problem appears in the log. The last column is the sum of all processes in the system. Here is a run where the numbers are measured as the server approaches the last entry in the list above. > 15:26:15: pop=3, imap=432, all=485, VSZ: 14353k, postfix:30, sys: 749 > 15:26:30: pop=4, imap=435, all=490, VSZ: 14497k, postfix:30, sys: 754 > 15:26:45: pop=3, imap=439, all=492, VSZ: 14560k, postfix:28, sys: 754 > 15:27:00: pop=3, imap=444, all=497, VSZ: 14711k, postfix:28, sys: 760 > 15:27:15: pop=4, imap=442, all=496, VSZ: 14673k, postfix:25, sys: 756 > 15:27:30: pop=4, imap=444, all=497, VSZ: 14721k, postfix:25, sys: 757 > 15:27:46: pop=3, imap=446, all=498, VSZ: 14756k, postfix:25, sys: 758 > 15:28:01: pop=3, imap=446, all=497, VSZ: 14718k, postfix:24, sys: 756 > 15:28:16: pop=3, imap=455, all=507, VSZ: 15018k, postfix:25, sys: 767 > 15:28:18: pop=3, imap=455, all=507, VSZ: 15018k, postfix:25, sys: 767 > 15:28:20: pop=3, imap=452, all=504, VSZ: 14931k, postfix:25, sys: 764 ---- service(pop3): fork() failed: Resource temporarily unavailable ---- > 15:28:22: pop=4, imap=452, all=505, VSZ: 14954k, postfix:25, sys: 770 > 15:28:24: pop=4, imap=452, all=505, VSZ: 14954k, postfix:25, sys: 770 > 15:28:26: pop=4, imap=451, all=504, VSZ: 14925k, postfix:25, sys: 769 > 15:28:28: pop=5, imap=451, all=506, VSZ: 14980k, postfix:25, sys: 771 ---- dovecot restart complete ---- > 15:28:30: pop=3, imap=11, all=22, VSZ: 485k, postfix:25, sys: 282 > 15:29:00: pop=4, imap=65, all=83, VSZ: 2293k, postfix:26, sys: 344 > 15:29:31: pop=3, imap=91, all=111, VSZ: 3129k, postfix:27, sys: 373 It always seems to happen shortly after the number of dovecot processes goes beyond 500.

Returning custom autoexpunge for user's INBOX

I want to be able to have custom autoexpunge settings for different users. I have it working for various folders (draft, junk, trash), but I can't seem to get it working for the user's primary inbox. In my user_query (I'm using mysql), I'm returning entries like this in the userdb_import field: namespace/inbox/mailbox/autoexpunge=5d namespace/inbox/mailbox/Drafts/autoexpunge=5d namespace/inbox/mailbox/Junk/autoexpunge=5d namespace/inbox/mailbox/Trash/autoexpunge=5d And everything works fine for Drafts, Junk, and Trash, but not for the main inbox. The logs show: Debug: Unknown userdb setting: plugin/namespace/inbox/mailbox/autoexpunge=5d I've also tried variations, trying to get the namespace correct for the main inbox, but they all get the same "Unknown userdb setting" error: namespace/inbox/mailbox/autoexpunge=5d namespace/inbox/mailbox/inbox/autoexpunge=5d namespace/inbox/mailbox/Inbox/autoexpunge=5d namespace/inbox/mailbox/INBOX/autoexpunge=5d I suspect I'm just giving the wrong namespace for the primary inbox. What's the right way to do this? Tom

Hey guys, there seem to be a problem with wget and/or the unicode webserver. During the make process there are several files wich are download from the unicode server. I can access them manually but both curl and wget failing to get it. Are they any other mirrors or anyone else expiring this bug? Greetings

Unfortunately i have to continue this issue. During my last updates this problem is occured again. This are my versions: # 2.2.21 (): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.11 (6ddf62b87f60+) # OS: Linux 3.13.0-77-generic x86_64 Ubuntu 14.04.4 LTS I tried to configure the linebreaks in my plugin section of /etc/dovecot/dovecot.conf by: sieve_extprograms_input_eol = lf But it seems to have no effect. Is this configured the right way or i have to use 0.4.12? Currently it looks like this: plugin { sieve = ~/sieve/.dovecot.sieve sieve_before = ~/sieve_before/.dovecot_before.sieve sieve_after = ~/sieve_after/.dovecot_after.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute +editheader sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ sieve_dir = ~/sieve sieve_global_dir = /etc/dovecot/sieve/ sieve_extprograms_input_eol = lf } > > Regards, > > Stephan. > > Thanks, Hajo

Queries are not being sent to solr when search on server issued via imap client.
by ralph.jones＠modolingo.de 29 Feb '16

29 Feb '16

I traced the network communication with the solr server with tcpdump: sudo tcpdump -i any -A -vvv port 8080 I logged into the imap server via telnet (actually openssl) and issued the command ". search body <string>". About 20 results were returned within about half a second. Nothing was seen in tcpdump. When I issue "doveadm search box <string>", I can see the search string in the output of tcpdump and also in the solr logs. Solr seems to have been initialized correctly, in that when I issue a query via curl, I receive the correct results. I am using: dovecot 2.2.13 (debian jessie) libsolr-java 3.6.2+dfsg-5 relevant config: mail_plugins = fts fts_solr acl virtual plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ debug ... }

Dovecot sieve - How to check which username a mail is being delivered to?
by Yannik Sembritzki 27 Feb '16

27 Feb '16

Hi everyone, I am looking for a way to check which mailbox an email is being delivered to in a global sieve filter. After not being able to find some kind of variable that is populated by dovecot automatically, I tried to use the `Delivered-To` header. I tried a check like this: header :is "delivered-to" "<user(a)domain.org>" Unfortunately, this does not only match the first occurence of the header (which can be assumed is added by dovecot), but any occurence of this header in the email, which could be added due to previous deliveries and forwards, or just cause of malice. Is there any way to achieve this? Best regards, Yannik

Assertion crash: (idx * array->element_size < array->buffer->used)
by Joseph Tam 27 Feb '16

27 Feb '16

Log message: Traceback is hex gibberish: if symbolic traceback is needed, I'll recompile with "cc -g" and retest. Panic: file ../../../src/lib/array.h: line 219 (array_idx_i): assertion failed : (idx * array->element_size < array->buffer->used) (Similar to http://dovecot.org/pipermail/dovecot/2015-February/099771.html) IMAP command that provoked the crash: x1 FETCH 3 (BODY) Dovecot version: 2.2.19, Solaris10 (I don't think doveconf -n is relevant, but willing to provide if needed). It seems like a mailbox index issue. Removing, then recreating the indices gets rid of the crash. I saved these indices if it will help. Joseph Tam <jtam.home(a)gmail.com>

Different Quotas For Public Namespace
by Chris 26 Feb '16

Dear All, are different quotas for public namespace folders possible? They're in the same namespace. If I got it right, the wiki says there's one quota per namespace only? - Chris

Block public namespace mail when quota exceeded
by Chris 26 Feb '16

26 Feb '16

Dear All, is it possible to temporarily reject mails, when quota of public namespace subfolder is exceeded? I'd check folder size with a cronjob. Dovecot is using a system user, so I guess blocking post and insert in ACL isn't a solution? I don't want to set the folder to read-only, that users can still delete mails. Thank you in advance. - Chris
