[Dovecot] how to deliver when username and email differ
by Cory Coager 20 Oct '07

20 Oct '07

I have an Active Directory virtual setup and am using LDA to deliver to local recipients. Today I found a big problem with my configuration and not sure if this is fixable. Some of the users have multiple email addresses and the %n variable for user doesn't match their actual username. So if I have realname "Joe Bob" with a username of "joe" and an email of "jbob(a)somewhere.com", deliver will try to deliver to "jbob" and this is wrong. Here is the relevant part of my ldap config: user_attrs = mail,postOfficeBox=home user_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) pass_attrs = mail,postOfficeBox=home pass_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) Somehow I need to change the username from the LDAP lookup but it seems that the mail attribute does this already. If I switch the mail attribute with sAMAccountName the domain becomes NULL. Anyone know if this is fixable?

[Dovecot] Dovecot v1.0.3 -> Sieve "redirect" command returning Sendmail exit status 75
by Elisamuel Resto 20 Oct '07

20 Oct '07

Hello! My local setup here is Exim 4.68, DSPAM 3.8.0 and Dovecot 1.0.5. Entirely on MySQL tables for virtual hosts and authentication. Dovecot does the authentication for Exim. What I am having problems with, is a simple sieve script to redirect a message that matches the "X-DSPAM-Result" header as "Spam" to another email address. When this rule matches, deliver returns in the log (which is attached) that "Sendmail process terminated abnormally, exit status: 75" What would cause this, and how can I resolve it? Thanks. -- Elisamuel Resto <samuel(a)dragonboricua.net> ID: 0x18615F19 / FP: B66D 1C2A E8EE B922 1D9C D98F D2D5 FB61 1861 5F19

[Dovecot] Problem with bodystructure/partial fetch using 1.1*
by mikkel＠euro123.dk 20 Oct '07

20 Oct '07

Hi there I'm using dovecot-1.1b2/b3 with deliver. All information is stored in an SQL database and no errors related to this issue are written to the logs (actually I get no errors at all). I've run into at problem; FETCH BODYSTRUCTURE is broken after upgrading to dovecot 1.1b2 (same issue with 1.1b3). BODUSTRUCTURE only returns information from the first section (with incorrect content-type/disposition) and discards everything else. This problem is somehow related to deliver; IMAP returns the correct BODYSTRUCTURE for e-mails received before the upgrade, but an incorrect for ones received after the upgrade. This tells me that IMAP is working properly but somehow the MIME sections are being corrupted doing mail delivery (if I fetch the complete body nothing seems to be wrong). Also if I fetch a section something is not right - instead of just the section I get part of the Content-type header as well (but only half the header). Obviously this makes various webmail clients go somewhat crazy while Outlook/Thunderbirds dont mind (since they fetch the complete body and do the MIME parsing themselves). These are my compile options (GCC 3.4.3 on Solaris 10): CPPFLAGS=-I/opt/pkgsrc/pkg/include/mysql LDFLAGS=-L/opt/pkgsrc/pkg/lib/mysql ./configure --prefix=/opt/freeware/dovecot-1.1b2 --with-pop3d --with-deliver --with-mysql --with-prefetch-userdb --with-sql --with-gnu-ld --with-ssl=no --enable-header-install make; make install Everything else works flawlessly. Have anyone else experienced at problem like this?

[Dovecot] In 1.1.beta3, COPY cmd results in msg with Content-length: 0 and no text
by Eric Weaver 20 Oct '07

I run Thunderbird with message filters that sort mail into other folders, and this has killed me for the day. COPY commands (and I have verified this with a manual test) result in the message headers coming out correct but the body totally missing. Is this a known issue being addressed? Thanks Eric Weaver

Checking the link status of the NIC it showed that indeed duplexing was giving wrong results.

[Dovecot] Operations error with AD connections
by Maarten Vanraes 19 Oct '07

19 Oct '07

Hello, dovecot version: 1.0.beta3-3ubuntu5.5 OS: 2.6.15-26-server i686 GNU/Linux Ubuntu dapper filesys: ext3 authentication is with ldap (Active Directory) the problem is that after a while with a number of pop3 connections (8 people who have checking every 5 minutes), the ldap_search gives 'Operation Error' . we have tried to use the global catalog, but that doesn't solve the problem. the binding is the problem, we must use binding, cause we don't get a userPassword field. Right now, we have switched to courierLDAP and it works for now, we'll have to see if it persists (we have set an LDAP timeout variable, but don't know if it's related.) The thing is that we have lots of places where can setup something like this with AD, and that for now, we'll probably use courier. dovecot-ldap.conf: hosts = 172.17.80.1:3268 dn = CN=SPIC,OU=Beheerders,OU=Zonnegroep,DC=zonnewende,DC=local dnpass = xxxxxxxxx auth_bind = yes ldap_version = 3 base = dc=zonnewende, dc=local user_filter = (mail=%u) pass_attrs = uid=user,userPassword=password pass_filter = (mail=%u) user_global_uid = 5000 user_global_gid = 5000 any ideas on how to solve it?

[Dovecot] performance?/connectivity? issues after server upgrade
by Udo Rader 18 Oct '07

18 Oct '07

Hi, we are facing some weird performance issues after we upgraded on of our mail servers to a new Opteron 64bit machine. The problem we are facing is that mail retrieval from external clients is incredibly slow. Fetching a mail with say a size of 3MB takes 7 minutes vs. sending exactly the same mail back to our postmaster account is only a question of seconds. I've verified this with various customers and thus I am completely lost here. The only service affected with this massive slowdown seems to be dovecot but unfortunately I cannot think of a way to debug the issue ... System load is absolutely minimal. % dovecot -n # 1.0.5: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imaps imap pop3 listen: 81.16.98.99 ssl_listen(default): 81.16.98.99 ssl_listen(imap): 81.16.98.99 ssl_listen(pop3): ssl_cert_file: /usr/bestsolution/ssl/certs/mail.bestsolution.at.pem ssl_key_file: /usr/bestsolution/ssl/private/mail.bestsolution.at.pem ssl_parameters_regenerate: 24 disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 9 mail_extra_groups: mail default_mail_env: mbox:~/mail/:INBOX=/var/mail/%u mail_location: mbox:~/mail/:INBOX=/var/mail/%u mmap_disable: yes lock_method: dotlock maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u auth default: mechanisms: digest-md5 cram-md5 login passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix Any ideas welcome :-) -- Udo Rader bestsolution.at EDV Systemhaus GmbH http://www.bestsolution.at

[Dovecot] Released v1.1.beta3
by Timo Sirainen 18 Oct '07

18 Oct '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta3.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta3.tar.gz.sig Please try and report any bugs. Beta2 still had a few bad bugs, but I'm hoping this release is near a usable state. I've been a bit busy with school lately so I haven't had time/energy to answer mails in here. The main reason has been this lab course (biochemistry) which ends on friday, so I'll try to start answering mails sometimes next week. Changes since beta2: - SORT fixes. Still buggy? - If Date: header doesn't exist or is broken, fallback to INTERNALDATE (as required by newer sort drafts, which I hadn't noticed before, v1.0.6 will have this too) - Log fatals/panics as such, instead of converting them to errors. - Don't bother logging "returned error 89" if the child process logged a fatal before that. - dovecot.index.cache file may have been updated wrong when saving messages causing all kinds of problems if it was - Some crashfixes

Hello all Tomorrow is the day , I'm gonna migrate all our mailboxes and imap folders from our old mailhub to the new one. In the same time I will migrate from UW to Dovecot , I've read all the stuff about it on the Dovecot web site. I have one question , do I have to care about the .imap cache directory created by Dovecot in any way or will it be "all automatic" when starting Dovecot ? Many thanks -- Cordialement Frank Bonnet

[Dovecot] iPhone 1.1.1 problems.
by Mike Meyer 18 Oct '07

18 Oct '07

I'm having problems with the iPhone client in the 1.1.1 version of the iPhone software. Things with other clients work fine, and the iPhone worked fine before it was upgraded to 1.1.1. Other phones on 1.1.1 failed. I'm still working on testing against the client with the iPhone 1.0.2 software on it. The problem is that the client simply doesn't connect to dovecot. I can see the packets passing back and forth in a number of ways, but haven't been able to see the contents. I tried turning on raw logging, but don't get log files for accesses from the iPhone. What I get are lines like so: Oct 13 00:08:34 bhuda dovecot: imap-login: Disconnected: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1, TLS Turning off SSL both ways, and the message changes to: Oct 13 18:21:38 bhuda dovecot: imap-login: Aborted login: rip=xxx.xxx.xxx.xx2, lip=xxx.xxx.xxx.xx1 Tweaking the logging in the firewall reveals something interesting: apparently the phone makes the connection to 993, then dovecot drops the connection, but the phone keeps sending to it (and yes, I've tried setting the firewall to allow arbitrary traffic between the phone and the server). So, first question: is anyone who has clients using iPhone software version 1.1.1 working willing to share config information? Second question: suggestions for things to try to solve the problem? (Other than talk to apple as that process is underway)? For instance, a recipe to sniff the text of the interchange? Final question: Any other information I can provide that might help debug this?

[Dovecot] namespace prefix issue with avelsieve and dovecot v1.1beta2
by Martin Konopka 16 Oct '07

Hi, I have installed dovecot v1.1.beta2 with the sieve plugin v.1.1.2. I have configured the following namespace: namespace: type: private separator: . prefix: INBOX. location: inbox: yes hidden: no list: yes When I create a rule which should move messages into the subfolder "Junk", Dovecot's deliver seems to ignore the namespace and creates a new folder .INBOX.Junk . I think I read somewhere that in Dovecot v1.1+ deliver supports namespaces? Or have I misconfigured something? Thank you!

[Dovecot] Error: net_connect(/var/run/dovecot/auth-master) failed: Resource temporarily unavailable

[Dovecot] Logging client commands (patch)
by Zach Bagnall 12 Oct '07

12 Oct '07

This might be useful to someone so I'll throw it out there. Patch against 1.0.5 adds support for two new configuration params: pop3_debug_client_commands = TOP, RETR, DELE imap_debug_client_commands = FETCH, DELETE Obviously add in whichever ones you're interested in, or none, or comment them out completely. It'll log the appropriate events: Oct 12 18:30:18 kea dovecot: IMAP(zach): Client command: FETCH The parameters are included for POP3 events. Wasn't sure quite how to do the same for IMAP and for my purposes it's not too important so imap command parameters aren't logged. Running smoothly here with a few dozen IMAP and POP3 users. Not suggesting this gets added to the codebase - I just needed it to help debug some other IMAP software and thought it might be useful. Zach.

[Dovecot] UIDL format for old UW pop3
by Oliver Hookins 11 Oct '07

11 Oct '07

Hi, we're trying to migrate from UW imap 2001a-10, which doesn't seem to use the UIDL format documented in the wiki. It seems to use a 16 character long MD5 hash of something. I've tried configuring Dovecot to do the same but the value comes out differently. The main thing that I can see is getting in the way is that the UIDL format is not documented sufficiently. There is no description of using numbers to restrict the length of the output, and no documentation of special features like X or M. Can someone shed some light on these? -- Regards, Oliver

Dear All, For the Dovecot.conf : protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir } For /var/spool/mail : -rw------- 1 root root 7168 Sep 24 23:02 aquota.group -rw------- 1 root root 8192 Sep 24 18:05 aquota.user -rw------- 1 edward mail 301709 Sep 24 23:27 edward But the Quota display is un-limited status... So, what mistake about the config ? Mine is FC6 System ! Thanks ! Edward.

[Dovecot] GSSAPI Cross-Realm Patch
by Zachary Kotlarek 11 Oct '07

11 Oct '07

I've written a GSSAPI cross-realm auth patch for people not lucky enough to have the __gss_userok function, though it should apply pretty cleanly with that patch in place as well. The patch is available at: http://zinux.cynicbytrade.com/svn/servers/dovecot/cross-realm.diff.bz2 It works for me on MIT-kerb, and I tested compilation against heimdal, but I don't have a cross-realm setup to test functionality under heimdal (though I also have no reason to think it wouldn't work). Since neither MIT nor heimdal provide a gss_userok() function, I used the krb5_userok() function. So if you're using a mechanism other than krb5 this won't work. But it's the same thing that OpenSSH and the apps distributed with heimdal do, so it seemed relatively safe. I also choose to append the krb5_userok() check rather than replace the gss_compare_name() check -- that way same-realm auth works for non-krb5 mechanisms, and my new code doesn't get called unless the same-realm check fails. If you don't care about other mechanisms it would be faster to bypass the gss_compare_name() check entirely. If this is something you'd like to mainline I'd be happy to standardize the coding style -- just point me to a style definition document. And if it doesn't hit the mainline I expect to maintain it for the foreseeable future, with updates at the same URL. Zach
