[Dovecot] v2.2.alpha1 released
by Timo Sirainen 08 Nov '12

08 Nov '12

http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz.sig I wanted to start stabilizing v2.2 release some months ago already, but I somehow got stuck adding more and more features. Now it looks like all of the necessary API changes are done, so everything I'm planning on near future can still be added to v2.2 without major changes. The redesigned dsync hasn't had much testing yet, so avoid running it with important mails. Would be nice if people started testing and reporting any bugs. I was going to create some kind of a test suite for testing all the possible syncing combinations and also doing some random stress testing, but I haven't had time for that yet. The new dsync supports doing very fast syncs by saving the resulting state and giving it as command line parameter to the next sync. So for example doveadm sync -s "" > new-state saves the state and doveadm sync -s `cat new-state` continues from the saved state. The replicator code doesn't yet support this. * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

Re: [Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 08 Nov '12

08 Nov '12

Hi, Yes w/o prefix work as expected, try to add a prefix like courier does (eg. Inbox.) It will not work as expected. Due I'm upgrading an old installed server, I've to keep everything as much transparent I can... it includes IMAP folder and subscription. Looking at that I've encountered that issue, and analyzed for fix it (thank you open source), not everyone will want to use/use k9.. but you can be 100% sure the stock client is there. Due that Google act like BlackBerry, Microsoft,etc.. (hovewer they will not fix it soon, or really respect the rfc), it's much simple add Namespace on prelogin banner then wait or have to tell someone to install another client for that mailbox. I didn't know the history, but looking at change log seems that idle as been put back to prelogin client for some kind of compatibility with their service. Anyway, the most important reason that got me to subscribe the mailing list for write those emails, is share with the community that problem and provide a solution.. for someone in the future that have the same problem and will search on internet for a solution (like I've does.. before analyze it on my own). If the workaround will be added to the wiki or will be put in the source.. the important thing is that there is a solution simple and fast (two.. the source modify, and the configuration file) and someone can find it.. (Sarcastic) And if the mayans were right we can't wait for google to fix it :p Best Regards Sent from Galaxy Nexus Robert Schetterer <rs(a)sys4.de> ha scritto: >Am 07.11.2012 08:13, schrieb Massimiliano Cianelli: >> Hello, >> >> My phone: >> Android ics 4.1.2 on galaxy nexus. >> And yes, stock mean the default client that come with the os in IMAP mode. >> >> I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. >> >> Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client. >> >> About the issue on Google code, there is thr issue on google code... but Google is a lot slow in fixing those things. >> http://code.google.com/p/android/issues/detail?id=1811 >> >> In a few hour I'll update the issue noticing where is hidden the problem. >> >> Regards >> Sent from Galaxy Nexus > >Hi , i shortly tested this with android sdk jelly bean 4.1.1 and "my >setup" dovecot 2.1.10 with included orginal android mail app in imap mode, >,leaving IMAP prefix blank, everything works as expected, no double >shown inbox, namespace problems etc >so you might have to fit your namespace setup. >Also you might follow allready given advice from here. > >Anyway , i understand you using "stock client" >but you have to understand that the producers of mail clients >optimize their stuff fitting best in their own server structure >making money with it, therefor their motivation coding better imap code >is not very high, same case is for outlook and microsoft >however, i would say, fixing bugs is on the google site here, looks like >there is patch >at >http://code.google.com/p/android/issues/detail?id=1811 >and the issue seems long known > >i dont see any hard relation to dovecot in this case >meanwhile using k9mail seems the best way to workaround >there are lots of other bugs around android versions >over the years i dont expect google to fix them > > >> >> Robert Schetterer <rs(a)sys4.de> ha scritto: >> >>> Am 06.11.2012 07:08, schrieb Ben Morrow: >>>> At 6AM +0100 on 6/11/12 you (Massimiliano Cianelli) wrote: >>>>> Hi, >>>>> >>>>> My setup: >>>>> Dovecot 2 latest, installed to replace courrier IMAP, and off course >>>>> configured with the dot separator and all folder under INBOX.*. >>>>> >>>>> The problem: >>>>> My phone was driving me mad during the test, due that it will only >>>>> recognize Inbox. >>>>> >>>>> How found the solution: >>>>> I've started sniffing IMAP traffic on my server and ended up with one >>>>> difference: >>>>> On courier it ask for namespace, on dovecot it won't. >>>>> >>>>> I gives a better look, and noticed that courier show namespace >>>>> capability on prelogin banner, adding it too solved the problem. >>>>> >>>>> Reason: >>>>> Android ICS stock client seems do not honor the capability gived after >>>>> the login. >>>> >>>> See http://wiki2.dovecot.org/Upgrading/2.0?highlight=%28capability%29 ; >>>> you need to set imap_capability and/or get your client fixed. >>>> >>>> Ben >>>> >>> >>> Hi, first ,what is the exact meaning of >>> >>> "Android ICS stock client" >>> >>> do you mean default included email client in standard android in imap >>> mode, when yes, which version of Android , i like to test my own >>> however is there changelog/code etc at google for this behave? >>> >>> conf example >>> >>> # Override the IMAP CAPABILITY response.

So, as described at http://wiki2.dovecot.org/SharedMailboxes/Shared I have configured a namespace like this: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } In one user (user1) I have configured ACLs so another one (user2) has access to a folder. Now, I want to susbscribe user2 to this folder. The problem I have is that whenever I try to list folders for this user (running thunderbird client) I get a panic and an error in the dovecot server (I have attached the complete log). The error says: Nov 6 11:58:56 myotis30 dovecot: auth: Error: userdb(user1): client doesn't have lookup permissions for this user: userdb uid (113246) doesn't match peer uid (14585) (change userdb socket permissions) Nov 6 11:58:56 myotis30 dovecot: auth: Debug: master out: FAIL#0112 Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: user user1: Auth USER lookup failed Nov 6 11:58:56 myotis30 dovecot: imap(user2): Debug: auth input: Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: Couldn't create namespace 'shared/' for user user1: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota It seems that imap process running for user2 is trying to a user lookup that fails. So I have manually tried it root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user2 userdb: user2 home : <homeDirectory> uid : 14585 gid : 404 root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user1 doveadm(user2): Error: user user1: Auth USER lookup failed doveadm(user2): Error: userdb lookup failed for user1 I have checked the socket permissions, but they are 0666 (if I'm looking the right socket): root@myotis30:/etc/dovecot/conf.d# ls -l /var/run/dovecot/auth-userdb srwxrwxrwx 1 dovecot root 0 nov 6 11:43 /var/run/dovecot/auth-userdb In fact, I have tried to put all sockets with permissions 0666 and 0777, but the error persists.

[Dovecot] LDAP congestion
by Bernhard Schmidt 07 Nov '12

07 Nov '12

Hello, I've been asked to have a look at a misbehaving mail server of some colleagues today where almost all logins where failing or excessively delayed, while the LDAP database itself was pretty fast. They run Dovecot 1.2.11 (yes, I know, stoneage) against an LDAP server run by a 3rd party, auth_bind=yes (required). The problem is that this third party LDAP server delays bindResponse 3 seconds when the password is wrong. A user wanted to login every 2-3 seconds this morning with the wrong password, which effectively killed the system because the LDAP connection was mostly stalled waiting for the auth timeout. >From a previous discussion with Timo I know that bindRequests cannot be parallelized in LDAP, so the problem does not come completely unexpected. Other than removing the failure delay in the LDAP server, is there anything one can do? If there is any change in newer Dovecot versions about that please tell me so I can encourage them to upgrade, but I haven't seen anything in the changelog. Any way to get several LDAP workers/connections for passdb in parallel? Thanks, Bernhard

[Dovecot] "starting" dovecot
by Dave Abrahams 07 Nov '12

My system never issues the "dovecot start" command. I do, however, run /usr/local/libexec/dovecot/imap on port 9xxx. I talk to the server through port 9xxx and through the preauth tunnel. Is this arrangement OK? Are there some things that will only work if "dovecot" is invoked?
