[Dovecot] Dovecot shared library to replace libc-client
by Asheesh Laroia 03 Jul '12

03 Jul '12

Hi all Dovecotters, Lots of programs (e.g, PHP) link to a library called c-client, which is a derivative of the original IMAP implementation, UW IMAP. (For those new to UW IMAP, read here: http://www.washington.edu/imap/ ) UW IMAP is not in as much of active development as it used to be, so I am curious: I see there is a dovecot shared library. I haven't looked into the details, but here are things I'm interested in: 1. Replacing libc-client's use as a client library In Debian, for example, you can search for packages that depend on this library as a client. It looks like this: $ ~ apt-cache rdepends libc-client2007e libc-client2007e Reverse Depends: uw-mailutils uw-imapd libc-client2007e-dev ipopd prayer php5-imap mailsync libmail-cclient-perl asterisk aolserver4-nsimap uw-mailutils libc-client2007e-dev prayer php5-imap mailsync libmail-cclient-perl asterisk-voicemail-imapstorage Let's say, hypothetically, we wanted to switch php5-imap to using Dovecot where it currently uses libc-client. I envision creating libdovecot-c-client-alike that is a set of headers and a library that is API-compatible with (at least a subset of) c-client. You can call that a "compatibility shim." Then e.g. php5-imap could be given the path to those headers and the corresponding libdovecot-c-client-alike library, and when it thinks it is linking to c-client, it could instead link to the libdovecot-c-client-alike. This might be convenient if you want to limit how much of a public API is presented by the current "dovecot.so" that gets installed in e.g. /usr/lib/dovecot/. The compatiblity shim could have a small API, and if you don't want provide ABI guarantees within dovecot.so, the shim could dlopen() dovecot.so rather than link to it. 2. Use of Dovecot shared library within alpine, embedding the imapd Right now, the mail client "alpine" embeds a copy of the UW IMAP source. It uses this when accessing local mail spools, for example. If Dovecot's IMAPd were available as a shared library, perhaps with a c-client-like API, (although not necessarily -- it would be feasible to upgrade alpine to a different API), then alpine could use Dovecot's mail drivers directly. So, those two are the dream. Timo and others, what are your thoughts? Thanks for reading this far! -- Asheesh. P.S. The radical request #2 would be an excellent, decisive way to end a sad thread in the Debian bug tracker about Alpine + Maildir: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405762 .

[Dovecot] Authentication failed (migrate from 2.0.13 to 2.0.17)

[Dovecot] v2.1.8 released
by Timo Sirainen 03 Jul '12

03 Jul '12

http://dovecot.org/releases/2.1/dovecot-2.1.8.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.8.tar.gz.sig Most importantly fixes a pretty bad behavior of sending mailbox names as UTF-8 instead of mUTF-7 as required by IMAP RFC. I'm surprised nobody hadn't noticed this in v2.1.x tree before yesterday. I guess some clients might have translated the name to UTF-8 anyway and not noticed it, while others would have silently ignored the problem of not seeing STATUS updates. + pop3c: Added pop3c_master_user setting. - imap: Mailbox names were accidentally sent as UTF-8 instead of mUTF-7 in previous v2.1.x releases for STATUS, MYRIGHTS and GETQUOTAROOT commands. - lmtp proxy: Don't timeout connections too early when mail has a lot of RCPT TOs. - director: Don't crash if the director is working alone. - shared mailboxes: Avoid doing "@domain" userdb lookups. - doveadm: Fixed crash with proxying some commands. - fts-squat: Fixed handling multiple SEARCH parameters. - imapc: Fixed a crash when message had more than 8 keywords. - imapc: Don't crash on APPEND/COPY if server doesn't support UIDPLUS.

[Dovecot] Additional passdb result status
by Jürgen Pabel 03 Jul '12

03 Jul '12

Dear Dovecot-Team, I am implementing a plugin (for the pop3/imap process) that requires some data to provided from the authentication phase (a derivative of the password). For that, I have now implemented a passdb plugin that generates this data and I would like to "pass" this data down to the mail process (pop3/imap) via extra_fields in the reply of the authentication. The general idea is that my custom passdb plugin calculates the data, sets the extra_field and returns some error (authentication was not successful) so that the "real" passdb backend can be invoked to "really" validate the authentication data. However, in auth_request_handle_passdb_callback() the extra_fields are reseted unless the return code is PASSDB_RESULT_USER_DISABLED. But if that return code is used then any following passdb's aren't invoked any more - which makes sense with respect to user authenticiation. I would therefore like to propose that some IGNORE/CONTINUE-status to be introduced in auth/passdb.h, that would be handled in that extra_fields and possible other values are not reseted in order to allow such propagation of data from authentication process down to the mail process (which could be extracted from the reply string by parsing it). As a further implementation alternative (to the parsing of the reply string), I also propose that some new "environment" item be introduced (in auth_request) in order to allow such data passing in a generic manner. I hope you consider my proposal to be reasonable. If desired, I could implement this myself and provide a patch for merging (based on 2.0.x). If my proposal is generally unfavored, it would be great if any alternative approaches for my situation were suggested. Thanks. Regards, Jürgen PS: please reply to my e-mail (or CC me), as I have not subscribed to the dovecot list

Hello everybody, I am running debian wheezy for development and test, and I recently upgrade to dovecot 2.1.7 I am using LDAP lookups, and virtual users with the same UID/GID. Everything was working fine before, but now, I have this error when I try to send an email to a local account: -------------------------------------------------------- Jun 26 15:46:52 lapetus dovecot: lmtp(24518): Error: user user.test(a)indienet.com: Auth USER lookup failed Jun 26 15:46:52 lapetus dovecot: auth: Error: userdb(user.test(a)indienet.com,127.0.0.1): client doesn't have lookup permissions for this user: userdb reply doesn't contain uid (change userdb socket -------------------------------------------------------- However, even if I set the permissions to 0666, I still have the same error. Can you point me in the right direction to fix this, please? Kind regards, André Rodier

[Dovecot] Setting up mixed mbox and maildir
by Jonathan Ryshpan 03 Jul '12

03 Jul '12

I'm trying to set up a dovecot server for which mail arrives in an mbox, and mail is stored in a maildir. The wiki (see http://wiki.dovecot.org/Namespaces) refers to this as "Mixed mbox and Maildir". It advises handling this situation by creating two namespaces: one for the mbox and the other for the maildir. Each of these namespaces starts with namespace private { On the other hand the sample configuration in the documentation puts inbox in a namespace starting with: namespace inbox { # Namespace type: private, shared or public #type = private It appears that there has been a change in the configuration syntax after the wiki was written, and that the word following namespace no longer gives a property of the namespace, but rather its name. Is this correct? In any case, how should the configuration be modified to handle mixed mailboxes? Thanks - jon

[Dovecot] Proxy config help please

Hello, I am new to dovecot and I am initially trying to setup a basic imap proxy with password forwarding, I can start the dovecot service, connect and give it my password, and that is where I hang. My config is: root@imap-test:/etc/dovecot# doveconf -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-24-generic x86_64 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes debug_log_path = syslog first_valid_uid = 100 imap_capability = CAPABILITY IMAP4rev1 ACL BINARY CATENATE CHILDREN CONDSTORE ENABLE ESEARCH ESORT I18NLEVEL=1 ID IDLE LIST-EXTENDED LIST-STATUS LITERAL+ LOGIN-REFERRALS MULTIAPPEND NAMESPACE QRESYNC QUOTA RIGHTS=ektx SASL-IR SEARCHRES SORT THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN XLIST last_valid_uid = 200 mail_debug = yes mail_gid = 107 mail_uid = 107 passdb { args = proxy=proxy_always nopassword=y host=172.16.0.13 port=143 proxy_timeout=5 starttls=y ssl=any-cert driver = static } protocols = imap service imap-login { inet_listener imap { address = * port = 143 } } ssl = required ssl_cert = </etc/courier/imapd.pem ssl_key = </etc/courier/imapd.pem verbose_ssl = yes The system at 172.16.0.13 is a zimbra proxy. I can see in the logs that it initially complains about my ssl cert, and if I remove ssl=any-cert it fails because my cert is self signed, so I know it is talking to the proxy and doing starttls which is a requirement of zimbra. Unfortunately I have not found a way to see the full exchange between dovecot and my zimbra proxy other than tcp dump, which just shows a small packet exchange. Please let me know if I can provide any other information and thanks in advance for any help. -Zac

[Dovecot] Dovecot 2.1 stable packages for Debian?
by Krzysztof Trybowski 02 Jul '12

02 Jul '12

Hello all, it is strange, but Dovecot 2.x still didn't make it into Debian (not even backports). It exists in testing, but that's still a long wait. OTOH there are official packages built every day (referenced from the download page). This puzzles me: why isn't there a build created from each stable, released version of Dovecot, so that users of Debian Stable could benefit from the new version, and run it on production environment? Could you (I mean — the Dovecot team) provide such packages? This wouldn't require any major amount of work, since you already have daily builds produced. You would just have to run that building system once per each released version and keep it available for download. The reason for this is relatively simple: I'm about to implement a new mail server, and I'd like to keep to Debian Stable while using Dovecot 2.x. This will make future updates much easier, as I won't have to face 1.2 -> 2.0 migration on a production system. Regards, KT
