[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

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. Forcing it into the correct mode did not change anything, but finally replacing the card with a new one solved the riddle! Thanks for your help! Udo Rader

[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? PS: can you CC me? -- Maarten Vanraes BA NV: IT & Security

[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

[Dovecot] Migration to Dovecot
by Frank Bonnet 18 Oct '07

18 Oct '07

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
