Dumb question: dovecot include file
by Jerry 29 Mar '16

29 Mar '16

Dovecot has an include file option. What I am not sure of is why those files use both a *.conf and *.conf.ext extension. I assume both types are included by using the !include <FILE>.conf or !include <FILE>.conf.ext syntax. -- Jerry

mailbox prefix

29 Mar '16

dovecot version 2.2.13 hello, I try to make a new server just for me after having old one working for ages with Dovecot, Fetchmail, Squirrelmail, Procmail making new one with above plus Postfix using Maildir structure. I am having a bit of trouble understanding exactly what the namespace and prefix are. Is the "private/" prefix an internal thing with Dovecot ? Or is it supposed to be a real directory ? I'm not quite sure how to properly address the INBOX in Procmail, Squirrelmail, Postfix config. for example am I supposed to say inbox is ".private/.INBOX" cheers zemlik

Migrating to dovecot from gmail apps
by Phil Lello 28 Mar '16

28 Mar '16

Hi, I'm considering migrating away from gmail for my (one-man) company, and I'm trying to decide if dovecot is the right option (I'm committed to self-hosting). I'm a developer, so happy to do my own tooling if needed. *Is there currently a good webmail interface to dovecot, or work-in progress?* If not, would a web interface be out-of-scope for dovecot? I want to use SAML for authentication, so a solution that relies on POP/IMAP doesn't meet my needs - unless I add Kerberos into the mix, which is an additional learning curve, and possibly not widely supported. *Is there currently a good web admin interface to dovecot, or work-in-progress?* If not, would a web interface be out-of-scope? Since I prefer using password-protected SSH keys for shell access, and don't want to tie myself to a laptop (and would hate to use vim on a 3G/4G tablet), I'd like to be able to add/remove aliases and play with SIEVE and ACLs through any available browser. *How's the work on sharing messages between folders progressing?* Finally, and I hope you don't mind me asking, are you aware of a good JAVA based alternative to dovecot? I quite like the idea of using lucene indexing on mailboxes, so reducing the number of dependencies has a certain appeal. Best wishes, Phil Lello

Enabling tcpwrappers
by kepa 28 Mar '16

28 Mar '16

Hi all, I would like use Dovecot with tcpwrappers enabled to control remote access using hosts.deny and hosts.allow. A google search gave this response from the listserve, but it is several years ago: http://www.dovecot.org/list/dovecot/2013-April/089455.html Are these instructions for configuring the conf files still valid? Mainly: /etc/dovecot/dovecot.conf login_access_sockets = tcpwrap conf.d/10-master.conf: service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } Also: Which version of Dovecot at least is needed to enable tcpwrappers? Does the tcpwrap option need to be enabled during configure and build or is it already (and enabled in any distro binary repositories)? And is it dovecot, imap, or imaps in the hosts.allow/deny file as the service name? Thanks! Kepa

I am not the only one. You can google around and find many run into this situation and no one could help. Most just delete the dovecot and postfix and start over again. However, I cannot afford that because it took me at least 3 months to setup dovecot correctly with postfix to use virtual users. I don't have the time to spend another 3 months to set it up. The problem lies with auth and I think this is the only issue and it has to be that something is missing either in the configs or a file was deleted or link to it was broken.

Re: IMAP Idle

Hmm. I can't think of why dovecot wouldn't time out. I think maybe the problem is with your webmail system -- it's not detecting when a client connection goes away and releasing all the resources associated with that user. This is not a typical problem though -- most webmail software do not keep persistent IMAP connections open during a session unless they use some IMAP proxy. Are your IMAP connections connected to the webmail server or an IMAP proxy, and is that connection active (despite webmail user disappearing)? Joseph Tam <jtam.home(a)gmail.com>

Need help solving issue
by MARIA jamieson 26 Mar '16

26 Mar '16

Hi, I am using Dovecot 2.2.18 and have migrated from a 1.x versions. After this migration I had several errors and obsolete errors in logs. I fixed them and after all that I finally was able to run postfix and dovecot again. The problem I have facing right now is that in the mail logs and in the dovecot logs. I am getting auth errors. In mail log the postfix is spitting out: " fatal: no SASL authentication mechanisms" Dovecot is spitting this out "imap-login : Auth process broken (disconnected before auth was ready, waited 0 secs): ,user<>, the shows client ip, my server ip and then the 0 seconds connection etc. Error: auth: environment corrupt; missing value for DOVECOT_" That is what it spits out. I asked for help and many threads.I am using freebsd 10.2. I do use mysql for database. I need someone to explain what the error means and how I can fix it? Thank you for your time!

Re: Reappearing emails - IMAP trace
by Ron Cleven 26 Mar '16

26 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. > What mailbox format do you use? Are you able to reproduce this by running doveadm sync commands manually instead of letting replication do it? For example: > > - doveadm sync -s "" -d -u user@domain > state > - Run the UID STORE & UID MOVE > - doveadm sync -s "`cat state`" -d -u user@domain > > There have been some fixes, especially recentlyhttps://github.com/dovecot/core/commit/950a6e61d6c2dac961ce031bdd8b… sounds a bit similar although I don't really see how it would apply here. Would be a good idea to try anyway with v2.2.22.rc1 (which seems to be stable enough that I'll make v2.2.22 release soon). > > Anyway, I attempted a few times to reproduce it with your test but wasn't able to. I was out when you were kind enough to reply. To answer your question, we are using Maildir format. The trace I provided was based upon IMAP interactions with Roundcube (though the problem was reproducable with several mail clients). I left in a few more steps to make the trace look less contrived. However, I reduced it further to just a couple of connection sessions. What I found in that exercise that was not apparent to me in my prior posting was that the "STATUS INBOX" command that ultimately reveals the problem (it shows the message reappearing) only becomes "wrong" when it is done in a subsequent session. That is, even if I inject an artificially large delay after the "UID STORE" / "UID MOVE" commands before the "STATUS INBOX" command in the same session, that result is never "wrong". But, as soon as I open a subsequent IMAP session, the "STATUS INBOX" command then shows the problematic results. I have never dug into the Dovecot code base, but I assume this relates to how the session data is cached and how the replications update it. None of this is relevant if the problem has already been fixed, so I will endeavor to set up a couple of test boxes with the current version to verify. The link you provided does look quite hopeful. Thanks so much.

I had much the same situation where a user signed up with a roaming wireless carrier that assigned a new IP to the client whenever it got passed from one access point to another. Good fun when this person took a bus ride through the city, leaving orphaned connections in its wake. The IDLE disconnection timeout is hardwired in the Dovecot code http://wiki.dovecot.org/Timeouts It's set to the RFC minimum of 30min. You'll have to recompile Dovecot to lower this to a non-RFC compliant value. I'm not sure how this this will affect clients, but 30min seems to be overly generous. Joseph Tam <jtam.home(a)gmail.com>

NetApp NFS vs. ZFS and NFS for Maildir
by Alessio Cecchi 26 Mar '16

26 Mar '16

Hi, I'm evaluating to switch from NetApp to a ZFS appliance (like Qsan). Our setup is Dovecot, Maildir for email storage and NFS to share mailboxes (more than 30k users) across POP/IMAP and MX servers. NetApp NFS works fine also under high load but have some limitation for inode numbers per Volume and is expensive (but recently their prices have dropped). ZFS, I read, suggest to create many small Raid Group to increase IOPS, but this configuration (N Raid instead of one RAID-DP like NetApp) is more complex to manage, or not? Someone has experiences with ZFS and NFS(v3) in high load environments? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Hello, Since replication does not seem to work on Mac OSX, I will run doveadm sync by hand every few minutes. In order to improve efficiency, I would like to use state. I have tried a few ways, but I always get the following error doveadm(user): Error: Saved sync state is invalid, falling back to full sync: Invalid base64 data KBtMOd0181bQ/wAAoQsxE90181YBAAAAAQAAAAAAAAAAAAAAAAAAABtI+mg= Here is the code I use to sync : for user in $userlist ; do doveadm sync -u $user -s "/Users/_dovecot/.bin/syncStates/syncstate$user" tcp:xxx.xxx.xxx.xxx > "/Users/_dovecot/.bin/syncStates/syncstate$user" done Any idea on how I can correct the encoding error ?

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

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.

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?
by Kieran 22 Mar '16

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/ * * * ***********************************************************************
