[Dovecot] Dovecot, Postfix and SMTP AUTH....
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...

[Dovecot] LSUB vs LIST (hacked Apple Mail problem)
The LSUB command does not act like LIST when provided with an empty mask argument. LIST responds with the hierarchy delimiter: * LIST (\Noselect) . OK List completed. whereas LSUB doesn't return anything useful: OK Lsub completed. RFC 3501 doesn't specify what LSUB should do in this case, but Courier IMAP has LSUB act like LIST. The attached patch modifies imap/cmd-list.c to make Dovecot do the same. Why do I care about LSUB? I'm using a hack for Apple Mail that replaces its LIST command with LSUB (something like what's described here: http://www.macosxhints.com/article.php? story=20040407062603804), to prevent it from syncing public folders from the Exchange server at the office. The hack replaces _all_ LISTs with LSUBs, including the LIST Mail.app sends to discover the hierarchy delimiter. Since dovecot doesn't give it any information in response to LSUB , Mail.app defaults to using / as a delimiter, which means that trying to access a subfolder only results in an Invalid mailbox name error. While this isn't really a bug in Dovecot, it's not inconceivable that other people than me could be affected by this problem (macosxhints.com has a substantial readership). It's also tricky to diagnose, especially since the Invalid mailbox name message doesn't include the invalid mailbox name, so any bug reports you get are likely to eventually be filed under crazy [Mac] users. In fact, while Googling to figure out why Dovecot wasn't working for me, I came across at least one poster to this mailing list who had discovered that Mail.app was using / as a delimiter. I can't be sure, but I'm guessing that his problem was related to mine. Since the patch is tiny and doesn't hurt performance or make Dovecot do anything that contradicts the IMAP RFC, I hope you'll consider adding it to the official distribution. lsub-delimiter.patch Description: Binary data Eyvind Bernhardsen
[Dovecot] dovecot 1.0, namespace mbox
-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 ??

[Dovecot] bug? ldap auth CRAM-MD5
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_key_file: /etc/ssl/ssl.key
