I've haven't use gcc on AIX for years :-) So in my opinion a common problem with xlc (or better xlc and AIX) is the shared object handling. Libtool seems to fix most of the problems.

[Dovecot] Dovecot, Postfix and SMTP AUTH.... one more time...
by Bartosz Toczek 26 Apr '07

26 Apr '07

Hello. I've notice a problem with SMTP AUTH in postfix with dovecot. My configuration is based on Postgresql. I've created a function in postgresql which returns password and username and attached it to password_query. Query looks like this password_query = SELECT username_out as username, password_out as password FROM get_password(lower('%n'),lower('%d')); Problem is when get_password returns something like this... vmail=# SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: duration: 2.342 ms statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); username | password_out ----------+-------------- | (1 row) It returns 1 empty row.... When this is attached to postfix with smtp auth with such configuration # SMTP AUTH broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth my serwer starts to be open relay... I now that it returns empty string for username and password... so where is the password checked... if I dont send password as a parameter to my function. Definition of the function looks like this: CREATE FUNCTION get_password("login" character varying, "domain" character varying, OUT username_out character varying, OUT password_out character varying) RETURNS record Can you help with that... BT

[Dovecot] dovecot 1.0, namespace & mbox
by Stefan Klatt 25 Apr '07

25 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, i try to use a new namespace with mbox parallel to my working maildir configuration. With this i have a few interesting effects: - - dovecot doesn't use the CONTROL statement and generate a .subscriptions file at the namespace directory. The INDEX statement is used. - - dovecot can work with subdirectories even mbox is used - - I can't work with namespaces under Thunderbird till i have a mbox file manually there. an subscription or construction of a new mbox file isn't possible :-( but this seems like one of the (handling?) bugs of Thunderbird - - Why can't i delete a Folder at an namespace? Dovecot complains "Can't rename mailbox to another storage type". Probably this is only a config issue. - - if i use as the first character for the prefix an # like #Archiv dovecot dosen't recognize the complete prefix statement at this namespace. The output of "dovecot -n" is the same except the prefix statement. I thought # is a legal character? A folder can start with it. Any ideas ?? Here is the output of dovecot -n : [root@cac etc]# dovecot -n # /etc/dovecot.conf ssl_cert_file: /etc/pki/tls/certs/cac.is-a-geek.com.cert ssl_key_file: /etc/pki/tls/private/cac.is-a-geek.com.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_extra_groups: email dotlock_use_excl: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins: zlib mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle namespace: type: private separator: / location: maildir:/srv/imapd/user/%u/maildir inbox: yes namespace: type: public separator: / prefix: Public/ location: maildir:/srv/imapd/shared/public/maildir:CONTROL=/srv/imapd/user/%u/shared-settings/public/control:INDEX=/srv/imapd/user/%u/shared-settings/public/index namespace: type: public separator: / prefix: Archiv/ location: mbox:/srv/imapd/shared/archiv/maildir:CONTROL=/srv/imapd/user/%u/shared-settings/archiv/control:INDEX=/srv/imapd/user/%u/shared-settings/archiv/index auth default: passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: static args: uid=600 gid=600 - -- CaC, Computer and Communication Inhaber Stefan Klatt Triftstrasse 9 60528 Frankfurt Germany Tel.: +49-(0)172-6807809 Tel.: +49-(0)69-67808-900 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGL47E+AkeCg4UPr4RApGVAJ9mvhvZAFEcamaSJcL7DTOTLjp4GgCfYkrz tsCThhIsYjCVH1pkPJIq2Go= =hCRf -----END PGP SIGNATURE-----

[Dovecot] bug? ldap auth CRAM-MD5
by André Höpner 25 Apr '07

25 Apr '07

Hello list, our users are authenticated against ldap-server. anything works fine... dovecot: imap-login: Login: user=<xxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured but now we want to use secure passwords and not only plain over ssl. so we configured dovecot to use cram-md5 and configured the ldap-server with CRAM-MD5 passwords. as client we used thunderbird 2.0 and a webfrontend called roundcube. that does not work, because the server gives... dovecot: auth(default): ldap(xxx,127.0.0.1): Password mismatch then we tried to use DIGEST-MD5. we changed the ldap password to the created one with dovecotpw. but this doesnt work too. thunderbird requests CRAM-MD5 and not DIGEST-MD5. so the log says: dovecot: auth(default): password(xxx,127.0.0.1): Requested CRAM-MD5 scheme, but we have only DIGEST-MD5 imap-login: Aborted login: user=<xxx>, method=CRAM-MD5 after that we changed the password back to CRAM-MD5, but we mad the failure not to delete the DIGEST-MD5 value. so the users had 2 passwords set... {CRAM-MD5}e02d374fde0dc75a17a557039a3a5338c7743304777dccd376f332bee68d2cf6 {DIGEST-MD5}358aefa044c08e6c19711c8117714fb0 password is "test" in both cases. on the next try we start thunderbird it works. i dont know why and the log of dovecot says... auth(default): ldap(xxx,127.0.0.1): Multiple password values not supported imap-login: Login: user=<xxx>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured user was logged in using CRAM-MD5. it's not nice but it works. anyone have an idea why? because of apache-module to auth against ldap and apache doesnt support nor CRAM-MD5 or DIGEST-MD5 we have set the password third time using MD5. So every user has three same passwords with different encryptions. Not nice - but it works. But what can we do to change this. I dont like to set passwords three times. our configuration: # /etc/dovecot/dovecot.conf ssl_cert_file: /etc/ssl/ssl.pem ssl_key_file: /etc/ssl/ssl.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: mbox:/var/mail/dovecot/%n:INDEX=/var/mail/dovecot/indexes/%n mail_plugins: quota imap_quota auth default: mechanisms: plain login cram-md5 digest-md5 verbose: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf plugin: quota: maildir:storage=1024 ------------- # /etc/dovecot/dovecot-ldap.conf hosts = 127.0.0.1:389 dn = cn=dovecot,dc=xxx,dc=com dnpass = dovecot sasl_bind = no sasl_mech = DIGEST-MD5 tls = no auth_bind = no ldap_version = 3 base = ou=People,dc=xxx,dc=com scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = DIGEST-MD5 ------------- best regards Andre

[Dovecot] upgrading RHEL4 to RHEL5 - dovecot 0.99 to 1.0rc15
by Götz Reinicke 25 Apr '07

25 Apr '07

Hi, now that a lot off software is updated e.g. RedHat EL and dovecot got finaly final :-) we plan to upgrade our mailserver from RHEL4 dovecot 0.99 to RHEL5 with dovecot 1.0rc15 - the rpms provided by Red Hat. I've read the upgrading Dovecot manual from here http://wiki.dovecot.org/UpgradingDovecot, but yust to get things right I'd like to ask some questions: Simply spoken, we use the basic default dovecot-config, mbox format and imaps/pop3s. So will there be any big trouble to just use the most default settings of the 1.0 config file? Or which options are compleatly different? Dose there exist a migration how to beside the dovecot upgrade from the wiki? Thanks for hints and tips!

[Dovecot] disabling pop/imap per mail address?
by Armijn Hemel 25 Apr '07

25 Apr '07

hello, first of all I want to say thanks to Timo for Dovecot 1.0. We've been running it in production at the company where I work and we're very pleased with it. Good job! One thing that we were wondering about today is if we can disable a certain protocol depending on the mailbox. So for example: user A can access via pop3s and imap, user B can only access via pop3, user C can use only imaps, and so on. thanks! armijn PS: am I assuming correctly that IMAP namespaces will make it possible to have shared IMAP folders with Dovecot? I'm still a bit of an IMAP dummy -- --------------------------------------------------------------------------- armijn(a)uulug.nl | http://www.uulug.nl/ | UULug: Utrecht Linux Users Group ---------------------------------------------------------------------------

[Dovecot] Experience with Dovecot + Sieve + Webmail?
by Steffen Kaiser 24 Apr '07

24 Apr '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, there were some posts into this lists regarding Webmail interfaces and Sieve. What are the experiences with them? I need a webmail frontend that is capable of IMAP, supporting dovecot's namespaces, verifying PGP and managing Sieve in conjunction with Dovecot. I found two mature products, I also saw posts about, so I'm going to ask. Some posts on this list suggest that some are using SquirrelMail/avelsieve and some Horde (IMP/Ingo). What are the experiences with them? Are they stable and are there configuration glitches (there is a thread about a bug in avelsieve, for instance). How do they interact with Dovecot in order to find the user's homedirectory to get/put the Sieve script? Maybe it's offtopic for the Wiki, but would you mind share your configuration on the Dovecot Wiki?

[Dovecot] message-of-the-day feature?
by Steven F Siirila 24 Apr '07

24 Apr '07

For lack of a better name, we are interested in a feature where one could get a notice out to all Dovecot users as quickly as possible, possibly without going through an MTA even. Given a message and a list of userids we could certainly do a mailing on the MDA server itself going through both Postfix and Dovecot LDA. However, we were wondering what other options we might have in Dovecot. For example, would it be possible to place the message into some file which Dovecot periodically checks for, and if the file exists, either present it to the user as a new message, or automatically deliver it at that time via Dovecot LDA? -- Steven F.
